PHARMACOLOGICAL EVALUATION OF COMMERCIALLY AVAILABLE POLYHERBAL FORMULATIONS FOR HEPATOPROTECTIVE AND ANTIOXIDANT ACTIVITIES

Polyherbal formulations, are frequently used to treat liver dysfunction, preserve the liver, and regenerate the liver. This research was carried out to determine whether or not polyherbal formulations could protect the livers of mice exposed to carbon tetrachloride -induced hepatotoxicity. 13 groups (n = 6) were generated at random from 78 male albino rats: Group I (serving as the normal control), Group II (containing only carbon tetrachloride), Group III (combining silymarin at a dosage of 100 mg kg-1 with carbon tetrachloride), and Groups IV–XIII (combining carbon tetrachloride with different brands of commercially available formulations). Serum levels of hepatic enzymes were analyzed to determine hepatic biochemistry and the extent of liver damage. Antioxidant activity analysis and histopathological analysis of the formulations were also conducted. The commercial formulations significantly (P < 0.01) lowered high liver biochemical markers, as validated by histological findings. Likewise, these formulations also displayed a strong antioxidant potential.

Evaluating the hepatotoxic versus the nephrotoxic role of iron oxide nanoparticles: One step forward into the dose-dependent oxidative effects

The present study has been designed to detect the dose-dependent effect of iron oxide nanoparticles (IONPs) on the liver and kidney of rats by evaluating three different doses 30, 300, 1000 mg/kg/day IONPs for 28 days. Forty rats were divided into four groups; I (control), II (low dose), III (medium dose) and IV (high dose).There also was a statistically-significant elevation in the serum levels of hepatic enzymes; AST and ALT in medium & high dose. The elevation of serum ALP, on the other hand, was significant in all IONPs doses.There was significant elevation in the levels of urea creatinine, and MDA in the medium and high doses of IONPs. The activity of superoxide dismutase (SOD) and glutathione peroxidase (GPx) showed significant decrease in the high dose only compared to the control group.The serum iron levels increased in a dose-dependent manner in the IONPs-treated groups with highly significant increase in the moderate and high dose groups.On comparing the effect of different doses of IONPs between the liver and kidney, the high dose revealed statistically significant difference (p < 0.05) in the area percent of collagen deposition (54.4 ± 3.9 versus 6.1 ± 2.6) and alpha smooth muscle actin (α-SMA) reaction (7.7 ± 1.5 versus 17.8 ± 4.3) in the liver relative to the kidney. The medium and high doses revealed statistically significant difference in optical density of Periodic acid Schiff (PAS) reaction (45 ± 3.4 versus 50.3 ± 1.8 in the medium dose, and 38.9 ± 6 versus 63 ± 3 in the high dose) and area percent of inducible nitric oxide synthase (iNOS) reaction (12.98 ± 2.7 versus 3.5 ± 0.5 in the medium dose, and 27.91 ± 1.5 versus 7.7 ± 0.6 in the high dose) in the liver relative to the kidney.

Bempedoic Acid for Primary Prevention of Cardiovascular Events in Statin-Intolerant Patients

The effects of bempedoic acid on cardiovascular outcomes in statin-intolerant patients without a prior cardiovascular event (primary prevention) have not been fully described. To determine the effects of bempedoic acid on cardiovascular outcomes in primary prevention patients. This masked, randomized clinical trial enrolled 13 970 statin-intolerant patients (enrollment December 2016 to August 2019 at 1250 centers in 32 countries), including 4206 primary prevention patients. Participants were randomized to oral bempedoic acid, 180 mg daily (n = 2100), or matching placebo (n = 2106). The primary efficacy measure was the time from randomization to the first occurrence of any component of a composite of cardiovascular death, nonfatal myocardial infarction (MI), nonfatal stroke, or coronary revascularization. Mean participant age was 68 years, 59% were female, and 66% had diabetes. From a mean baseline of 142.2 mg/dL, compared with placebo, bempedoic acid reduced low-density lipoprotein cholesterol levels by 30.2 mg/dL (21.3%) and high-sensitivity C-reactive protein levels by 0.56 mg/L (21.5%), from a median baseline of 2.4 mg/L. Follow-up for a median of 39.9 months was associated with a significant risk reduction for the primary end point (111 events [5.3%] vs 161 events [7.6%]; adjusted hazard ratio [HR], 0.70 [95% CI, 0.55-0.89]; P = .002) and key secondary end points, including the composite of cardiovascular death, MI, or stroke (83 events [4.0%] vs 134 events [6.4%]; HR, 0.64 [95% CI, 0.48-0.84]; P < .001); MI (29 events [1.4%] vs 47 events [2.2%]; HR, 0.61 [95% CI, 0.39-0.98]); cardiovascular death (37 events [1.8%] vs 65 events [3.1%]; HR, 0.61 [95% CI, 0.41-0.92]); and all-cause mortality (75 events [3.6%] vs 109 events [5.2%]; HR, 0.73 [95% CI, 0.54-0.98]). There was no significant effect on stroke or coronary revascularization. Adverse effects with bempedoic acid included a higher incidence of gout (2.6% vs 2.0%), cholelithiasis (2.5% vs 1.1%), and increases in serum creatinine, uric acid, and hepatic enzyme levels. In a subgroup of high-risk primary prevention patients, bempedoic acid treatment was associated with reduced major cardiovascular events. ClinicalTrials.gov Identifier: NCT02993406.

The hepatoprotective effects of Herbt Tea Essences on phenanthrene-induced liver damage in mice

Phenanthrene (Phe), one of the most frequently occurring pollutants in nature, can cause substantial damage to the human liver. Herbt Tea Essences (HTE), a kind of black tea extract with strong anti-inflammatory activity, can protect humans against disease. Currently, whether HTE can protect the liver from Phe-induced hepatotoxicity remains unclear. Herein, we explore the protective effects of HTE against Phe-induced hepatotoxicity. Our results showed that Phe exposure could significantly induce liver damage and increase serum hepatic enzyme levels in mice. HTE could prevent liver damage and recover the expression levels of inflammatory factors. Furthermore, we found that HTE suppressed the excessive activation of the nuclear transcription factor kappa-B and transforming growth factor-β/SMAD signaling pathways to alleviate Phe-induced liver inflammation and fibrosis. Overall, our data showed that HTE treatment could be a new preventive means for Phe-induced liver disease.

Hepatotoxic Effect of Methotrexate on Serum Hepatic Enzymes with Amendment by Sulforaphane in Albino Rats

Objective: To evaluate the variations in serum levels of hepatic enzymes in methotrexate damaged hepatic tissue with improvement by sulforaphane. Design of research study: Experimental research study. Duration of research study: this research study was piloted in BMSI, JPMC &amp; total period was one week &amp; three days. Materials and Methods: For research work 40 adult albino rats of 0.2-0.3kg were selected. Time period for final study was 1 week and 3 days because animals started dying after 10 days due to hepatotoxic effect of methotrexate. Animals were separated into 4 groups, A1 was control, B1 animals were Injected Methotrexate intraperitoneally. C1 animals were Injected Methotrexate intraperitoneally along with sulforaphane by N/G. D1 animals was given sulforaphane by N/G. At the end of study, animals were sacrificed &amp; blood was taken by direct cardiac puncture and send for lab investigation. Results: B1 animals presented with significant increase in serum levels of hepatic enzymes while C1 animals had slightly raised serum levels of hepatic enzymes. Practical Implication: These findings contribute further support to the hypothesis that variations in serum levels of hepatic enzymes in methotrexate damaged hepatic tissue are improved by sulforaphane administration. Conclusion: Research accomplishes that sulforaphane altered the unfavorable effects of methotrexate. Group B1 had substantial raise in serum levels of hepatic enzymes whereas Group C1 serum had substantial decrease in serum levels of hepatic enzymes So our recommendation is that sulforaphane should be use with methotrexate to reduce its side effects. Keywords: Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), reactive oxygen species (ROS), methotrexate(MTX), glutathione (GSH), NADPH (nicotinamideadenine dinucleotide phosphate).

The palliative effect of mulberry leaf and olive leaf ethanolic extracts on hepatic CYP2E1 and caspase-3 immunoexpression and oxidative damage induced by paracetamol in male rats

This study investigated the possible protective role of mulberry leaf (MLE) and olive leaf (OLE) ethanolic extracts against paracetamol (PTL)–induced liver injury in rats compared to silymarin as a reference drug. Initially, MLE and OLE were characterized using gas chromatography–mass spectrometry (GC/MS). Then, forty male Sprague Dawley rats were divided into five groups: the negative control group orally received distilled water for 35 days, the PTL-treated group (PTG) received 500 mg PTL/kg b. wt. for 7 days, the MLE-treated group (MLTG) received 400 mg MLE/kg b. wt., the OLE-treated group (OLTG) received 400 mg OLE/kg b. wt., and the silymarin-treated group (STG) received 100 mg silymarin/kg b. wt. The last three groups received the treatment for 28 days, then PTL for 7 days. The GC–MS characterization revealed that MLE comprised 19 constituents dominated by ethyl linoleate, phytol, hexadecanoic acid, ethyl ester, and squalene. Moreover, OLE comprised 30 components, and the major components were 11-eicosenoic acid, oleic acid, phytol, and à-tetralone. MLE and OLE significantly corrected the PTL-induced normocytic normochromic anemia, leukocytosis, hypercholesterolemia, and hypoproteinemia. Moreover, the MLE and OLE pretreatment considerably suppressed the PTL-induced increment in serum levels of hepatic enzymes, including alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase. Furthermore, the PTL-induced depletion in antioxidant enzymes, including glutathione peroxidase, superoxide dismutase, and catalase, and the rise in hepatic malondialdehyde content were significantly reversed by the MLE and OLE pretreatment. Besides, MLE and OLE pretreatment significantly protected the hepatic tissue against PTL-induced DNA damage, pathological perturbations, and increased caspase 3 and CYP2E1 immunoexpression. Of note, OLTG showed better enhancement of most indices rather than MLTG. Conclusively, these findings imply that OLE, with its antioxidant and antiapoptotic capabilities, is superior to MLE in protecting against PTL-induced liver injury.

Synergistic effect of arginine and Lactobacillus plantarum against potassium dichromate induced-acute liver and kidney injury in rats: Role of iNOS and TLR4/NF-κB signaling pathways.

Our study was conducted to evaluate the synergistic effect of arginine (ARG) and Lactobacillus plantarum against potassium dichromate (K2Cr2O7) induced-acute hepatic and kidney injury. Fifty male Wistar rats were divided into five groups. The control group received distilled water. The potassium dichromate group (PDC) received a single dose of PDC (20 mg/kg; SC). The arginine group (ARG) and Lactobacillus plantarum group received either daily doses of ARG (100 mg/kg, PO) or L. plantarum (109 CFU/ml, PO) for 14 days. The combination group (ARG+L. plantarum) received daily doses of ARG (100 mg/kg) with L. plantarum (109 CFU/ml), orally for 14 days, before induction of acute liver and kidney injury. Forty eight hours after the last dose of PDC, serum biochemical indices, oxidative stress biomarkers, pro-inflammatory cytokines, histopathological and immunohistochemical analysis were evaluated. Combining ARG with L. plantarum restored the levels of serum hepatic & kidney enzymes, hepatic & renal oxidative stress biomarkers, and TLR 4/ NF-κB signaling pathway. Furthermore, they succeeded in decreasing the expression of iNOS and ameliorate the hepatic and renal markers of apoptosis: Caspase-3, Bax, and Bcl2. This study depicts that combining ARG with L. plantarum exerted a new bacteriotherapy against hepatic and renal injury caused by PDC.

Folic acid protects against tuberculosis-drug-induced liver injury in rats and its potential mechanism by metabolomics

Observational study indicated that folic acid (FA) supplementation may protect against tuberculosis-drug-induced liver injury (TBLI). The aim is to investigate the effect and mechanism of FA on TBLI in rats. Liver injury was induced by a daily gavage of isoniazid (INH) and rifampicin (RIF) in the model and FA groups. Rats in the FA group were also treated with 2.5 mg/kg body weight FA. Rats in the control group were not treated. Eight rats were used in each group. The severity of liver injury was measured by the serum levels of hepatic enzymes and histological score. The metabolites in serum and liver tissues were analyzed by HPLC-Q-TOF-MS/MS. FA treatment significantly reduced alanine aminotransferase and liver necrosis. Seventy-nine differential metabolites in the serum and liver tissues were identified among the three groups. N-acylethanolamines, INH and RIF metabolites, phosphatidylcholines, lysophosphatidylcholines, monoglycerides, diglycerides and bile acids were regulated by FA treatment, involving key metabolic pathways, such as N-acylethanolamine metabolism, INH and RIF metabolism, liver regeneration, inflammation alleviation and bile acid metabolism. RT-PCR and western blotting results confirmed the altered N-acylethanolamine metabolism and improved drug metabolism by FA. In conclusion, FA was protective against TBLI, which may be related to the regulation of N-acylethanolamine metabolism and drug detoxification by FA.

Dietary Parsley Seed Mitigates Methomyl-Induced Impaired Growth Performance, Hemato-Immune Suppression, Oxidative Stress, Hepato-Renal Damage, and Pseudomonas aeruginosa Susceptibility in Oreochromis niloticus.

The present experiment investigated the potential protective role of parsley (Petroselinum crispum) seed meal (PSM) in alleviating methomyl (MET)-adverse impacts on growth, whole-body composition, hematological indicators, hepatorenal function, immune response, oxidative status, and disease resistance to Pseudomonas aeruginosa. For this purpose, 225 healthy Nile tilapia (Oreochromis niloticus) were allotted into five groups (45 fish/group in triplicate). One group was reared in clean water and fed a non-supplemented basal diet, while the other groups were exposed to 20.39 μg L−1 MET and fed a non-fortified basal diet or basal diets supplemented with 0.5, 1.0, or 2.0% of PSM for 60 days. The obtained data revealed significantly lower weight gain, feed intake, and specific growth rate, but higher feed conversion ratio and decreases in crude protein, lipid, and ash contents in the MET-exposed fish. Anemia, leukopenia, lymphocytopenia, and esonipenia were also obvious. Furthermore, MET-exposed fish had significantly higher serum levels of hepatic enzymes and renal damage products. Nevertheless, there was a significant depletion of enzymatic and non-enzymatic antioxidants and increased malondialdehyde, myeloperoxidase, and tumor necrosis factor-α levels in MET-exposed fish. The MET exposure significantly depressed lysozyme activity, nitric oxide, complement3, acetylcholinesterase activity, total proteins, globulin, and albumin levels in O. niloticus serum. Furthermore, pathological alterations in the liver and kidney were noted. The relative percentage of survival rate in MET-exposed fish was dramatically reduced on day 14 post-challenge with P. aeruginosa. The inclusion of PSM, on the other hand, greatly alleviated most of the MET-related negative effects. Taken together, the dietary intervention with PSM has a promising role in alleviating MET-deleterious impacts, rendering parsley seeds a viable aqua feed additive for O. niloticus.

Broyler Rasyonuna İlave Edilen Resveratrol ve Kurkumin Ekstraktlarının Serumda Biyokimyasal Parametreler ve Karaciğer Enzimleri Üzerine Etkileri

The aim of this study was to investigate the effects of resveratrol extract (RE) and curcumin extract (CE) added to diet on the serum biochemical parameters and hepatic enzyme levels as Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), and Gamma Glutamyl Transferase (GGT) of broiler. A total number of 200, 0-day-old male broiler chicks (Ross 308) were used in the study. The animals were divided into 5 groups; the control group was fed only basal diet but groups RE-1, RE-2, CE-1 and CE-2 had 250 mg/kg RE, 500 mg/kg RE, 250 mg/kg CE and 500 mg/kg CE, respectively, added to their diets. At the end of the study, 10 randomly selected animals from each group were slaughtered and blood was taken from the vena jugularis and used in the analysis. In the examinations, it was determined that the serum creatinine level in the group RE-1 and the Lactate Dehydrogenase (LDH) level increased significantly in the group CE-2 group. In addition, it was determined that the albumin/globulin ratio in the RE-2 group, and the magnesium (Mg) level increased significantly in the RE-1 and RE-2 groups. It was found to be statistically similar in all groups that serum glucose, cholesterol, triglyceride, urea, blood urea nitrogen (BUN), creatine kinase (CK), ALT, AST, ALP, GGT, amylase, total protein, albumin, globulin, calcium (Ca) and phosphorus (P) levels. As a result, it was observed that the additives applied did not have an effect on serum hepatic enzymes and partially affected other routine biochemical parameters.

Comparative Study on Serum Hepatic Enzymes between Normal Healthy Adults and Obese People of Rajshahi City

Background &amp; objective: Obesity is rapidly emerging as one of the major causes of non-alcoholic fatty liver disease (NAFLD), the early sign of which is elevated liver enzymes. But very few studies have yet been done in our country to find the association between overweight and obesity and levels of serum hepatic enzymes. The present study was undertaken to determine the association between overweight/obesity determined by body mass index (BMI) and serum hepatic enzymes.&#x0D; Methods: This cross-sectional analytical study was conducted in the Department of Physiology, Rajshahi Medical College, Rajshahi over a period of one year between July 2018 to June 2019 in collaboration with the Department of Biochemistry of the same Medical College. Based on certain predefined enrolment criteria, 33 overweight or obese (BMI ≥23 kg/m2) individuals (case) and 33 sex-matched apparently healthy adults (BMI &lt;23 kg/m2) (control) were included from the Rajshahi City. All the study subjects were then tested for serum hepatic enzymes (ALT, AST, ALP and GGT). The investigation findings obtained were compared between case and control groups.&#x0D; Result: The mean ages of the cases and controls were almost similar (31.1 and 29.4 years respectively, p = 0.576).All the serum hepatic enzymes but GGT were found to be significantly raised in the case group than those in the control group. The BMI was found to bear significantly linear relationship with serum ALT, AST and ALP (r = 0.709, p &lt; 0.001, r = 0.718, p &lt; 0.001 and r = 0.545, p &lt; 0.001 respectively) indicating that more than 70% of the variations in ALT and AST and 55% of the variations in ALP might be due to variation in BMI. When waist circumference was correlated with hepatic enzymes, it was found to correlate better than the BMI did with 70.3% of the variations in ALT, 77.2% of variations in AST and 57.4% variation in ALP being explained by waist circumference. However, WHR did not correlate well with hepatic enzymes. AST alone bears a weekly significant correlation with WHR, with only 28% of the variations in AST could be explained by WHR.&#x0D; Conclusion: The study concluded that all the serum hepatic enzymes but GGT are significantly raised in the overweight and obese individuals than those in individuals with normal BMI. The BMI bears significantly linear relationships with serum ALT, AST and ALP. A substantial proportion of the variations in ALT and AST could be explained by BMI. Waist circumference correlates even better than the BMI does. However, WHR is not a good predictor of serum hepatic enzymes.&#x0D; Ibrahim Card Med J 2021; 11 (1): 62-70

Hepatic Lipidosis in Association with Enterobacter Infection in New Zealand White Rabbit - A Case Report

In the present case study, a spontaneous hepatic lipidosis was observed in the 5-year old female laboratory New Zealand White rabbit. A history of asymptomatic animal having signs of anorexia, unresponsive and died within a short span. Further study of clinical pathological findings, showed increased levels of serum hepatic enzymes with no alteration of BUN and creatinine profile values. Systemic necropsy showed pale yellow discolouration of liver, lung oedema and pale discolouration of other vital organs. Histological analysis was done for vital organs. Microscopic examination revealed moderate infiltration of fatty changes with degeneration in liver, kidney and heart. Lung exhibited oedema with pneumonic changes. A growth of mixed enterobacteria was found in heart blood and lung samples culture. Based on gross morphological changes and histopathological findings the present case was diagnosed as hepatic lipidosis.

Corchorus olitorius L. Leaf Extract Protects Rats from Acrylamide-Induced Hepatic Injury

Acrylamide is a water-soluble compound that forms during the high-temperature cooking of starchy foods and has carcinogenic, neurotoxic, and genotoxic properties. Also, short-term exposure to acrylamide has been shown to cause significant hepatic injury in laboratory animals, along with disruption of antioxidant defense mechanisms due to excessive ROS production. Therefore, dietary antioxidants are believed to be useful in combating the negative effects of acrylamide. Corchorus olitoris L., also known as molokhia in Arabic, is a leafy vegetable which is shown to possess potent antioxidant and organoprotective properties. In this study, rats were administered with an aqueous extract of molokhia leaves to see if it could protect them against acrylamide-induced hepatic damage. Hepatic injury markers included serum total protein, total bilirubin, ALT, AST, and ALP, while oxidative stress markers included MDA, GSH, CAT, and SOD after dosing with three levels of extract (100, 250, and 500 mg/kg) for 21 days. Results indicated that the extracts substantially reduced elevated levels of bilirubin, ALT, AST, ALP, and MDA to normal levels at all doses. The extracts also brought serum protein, GSH, CAT, and SOD levels back to normal. Although the restoration of serum hepatic enzyme levels was dose dependent, no specific dose dependent relationship was found for serum proteins, MDA, GSH, CAT, or SOD activities. The study's findings show that molokhia leaves extract protects against acrylamide-induced hepatic damage by virtue of its good radical scavenging and anti-lipiperoxidative properties conferred by phenolics, flavonoids, and alkaloids.

Cosmetological competence of nail patches in combating onychomycosis-An approach to improve the quality of life

Onychomycosis (Tinea unguium) is said to be the most common cosmetological nail fungal infection. Dermatophyte is a type of fungus that causes this condition. Discoloration and thickening of the nail are found to be the common symptoms of all nail diseases. In this scenario, Onychomycosis is considered as one of the cosmetic problems that leads to cellulitis in adults and diabetic patients. Anatomical structure of the nail and disease manifestations made nail disorders as a difficult endeavor. Onychomycosis is chronic and difficult to eradicate. Many oral antifungal agents are available for the treatment of nail infections. The oral and parenteral administration of antifungal agents can elevate the serum hepatic enzyme levels and causes typical hepatocellular injury within a few weeks of therapy. The goal of this review is to study the role of transungal delivery systems (nail patches) as a promising tool for onychomycosis to encounter the clinical conditions of the patient. Longer therapies and technical treatment methods may frustrate the patients. This novel antifungal therapy helps to avoid the surgical removal of nail for onychomycosis patients. Eradication of issues with Onychomycosis can be achieved by an excellent delivery system with deeper drug release and drug retention in the nail cuticle. Patients who are suffered from onychomycosis are facing embarrassment and disfigurement in the society. So, this newer treatment solution can improve the quality of life of patients.1-3

Effects of Ribes khorasanicum hydro-ethanolic extract on streptozotocin-induced diabetic complications in rats.

The anti-diabetic effects of Ribes khorasanicum as a traditional remedy were investigated in diabetic rats. Thirty-five male rats were divided into five groups: control, diabetic, diabetic treated with metformin (300 mg kg-1; D+Met), diabetic treated with 250 and 500 mg kg-1 of Ribes khorasanicum hydro-ethanolic extract (D+Rib250 and D+Rib500). After six weeks of treatment, sera of overnight fasted animals were collected and used for measurement of glucose, insulin, lipid profile, urea, creatinine, and hepatic enzymes levels. Moreover, liver and kidney of rats were removed and used for measurement of oxidative stress including malondialdehyde (MDA), thiol content, and the activity of catalase (CAT) and superoxide dismutase (SOD). Streptozotocin (STZ)-induced diabetes increased the levels of serum glucose, triglycerides (TG), total cholesterol (TC), and LDL-C, urea, creatinine, hepatic enzymes, and kidney and liver oxidative stress markers, while decreased insulin and HDL-C when compared to control group. In all treated groups serum levels of glucose, TC, LDL-C, TG, and urea were decreased, while liver SOD activity was increased compared to the diabetic group. The D+Rib500 group had lower Serum glutamic pyruvic transaminase (SGPT), creatinine, and kidney MDA levels, but higher insulin, HDL-C levels, liver CAT activity, and kidney thiol content, and CAT activity compared to diabetic group. In D+Met group, serum levels of serum glutamic-oxaloacetic transaminase (SGOT), creatinine, and MDA of liver and kidney were decreased, while liver SOD activity was increased compared to the diabetic group. Based on our findings, treatment with Ribes khorasanicum improved diabetic complications, while the effect of a higher dose of the extract was comparable to metformin’s.

The single or combined Silybum marianum and co-enzyme Q10 role in alleviating fluoride-induced impaired growth, immune suppression, oxidative stress, histological alterations, and reduced resistance to Aeromonas sobria in African catfish (Clarias gariepinus)

High fluoride (FL) concentration in many areas of the world is of great concern. It poses a threat to aquatic life. Therefore, the current study was operated to scrutinize the efficiency of Silybum marianum (SM) and/or coenzyme Q10 (CQ10) dietary supplementation to rescue FL negative effects on the growth, hematological indicators, liver and kidney function, serum protein profile, innate immune parameters, oxidative status, vital organ architecture, and disease resistance to Aeromonas sobria. Two hundred and forty healthy Clarias gariepinus fish were alienated into eight groups in triplicate. The control group was fed a non-supplemented basal diet. The SM, CQ10, and SM + CQ10 groups were fed a basal diet fortified with 10 g SM/kg diet, 40 mg CQ10/kg diet, or SM + CQ10, respectively. The FL group was exposed to 73.45 mg FL/L water. The FL + SM, FL + CQ10, and FL + SM + CQ10 were exposed to FL concomitantly with SM, CQ10, and SM + CQ10, respectively. The experiment continued for 60 successive days. The results showed lower weight gain and specific growth rate but higher hepatosomtic index in the FL-exposed fish. An obvious leukopenic and anemic condition was detected. Also, a significant increase in the serum levels of hepatic enzymes and kidney damage products was apparent in FL-exposed fish. Nevertheless, exhaustion of the non-enzymatic and enzymatic antioxidants but elevated lipid peroxidation product (MDA) was noted. The FL exposure exhausted lysozyme activity, complement 3, nitric oxide, total proteins, albumin, and γ globulin contents in the serum of C. gariepinus. Moreover, diverse pathological alterations were detected in the liver, kidney, and spleen. After 14 days of A. sobria challenge, the relative survival rate percentage was significantly reduced in FL-exposed fish. On the contrary, the SM and/or CQ10 addition significantly reduced most FL-associated negative impacts. Conclusively, SM and/or CQ10 dietary supplements could be beneficial for alleviating FL deleterious impacts, thus affording advantageous aqua feed additive for C. gariepinus.

Immunomodulatory effects of thalidomide in an experimental brain death liver donor model

Brain death is characterized by a generalized inflammatory response that results in multiorgan damage. This process is mainly mediated through cytokines, which amplify graft immunogenicity. We investigated the immunological response in a brain death liver donor model and analysed the effects of thalidomide, a drug with powerful immunomodulatory properties. Brain death was induced in male Lewis rats. We studied three groups: Control (sham-operated rats in which trepanation was performed without inserting the balloon catheter), BD (rats subjected to brain death by increasing intracranial pressure) and BD + Thalid (BD rats receiving thalidomide after brain death). After 6 h, serum levels of AST, ALT, LDH, and ALP as well as systemic and hepatic levels of TNF-α, IL1-β, IL-6, and IL-10 were analysed. We also determined the mRNA expression of MHC Class I and Class II, NF-κB, and macrophage infiltration. NF-κB was also examined by electrophoretic mobility shift assay. Thalidomide treatment significantly reduced serum levels of hepatic enzymes and TNF-α, IL-1-β, and IL-6. These cytokines were evaluated at either the mRNA expression or protein level in liver tissue. In addition, thalidomide administration resulted in a significant reduction in macrophages, MHC Class I and Class II, and NF-κB activation. This study reveals that thalidomide significantly inhibited the immunologic response and graft immunogenicity, possibly through suppression of NF-κB activation.

Hepatic dysfunction in asphyxiated neonates: a prospective case: control study

Background: Birth asphyxia can lead to hypoxic damage to liver at cellular level which leads to release of liver enzymes in blood as well as altered liver function. This study aimed to study the alteration of hepatic function in birth asphyxia and correlate it with different stages of hypoxic ischemic encephalopathy (HIE).Method: A case control study was conducted at SMIMER Surat which involved 115 cases and 115 controls. Cases were full term neonates admitted in the NICU with an APGAR score of 6 or less at 1 minute of birth while controls were those neonates with an APGAR score of 7 or more. Blood samples were taken at 72 hours of life and liver function tests of the 2 groups were compared.Results: The difference in aspartate transferase (AST), alanine transferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP) levels of the cases and controls were statistically significant (p&lt;0.05). However, difference in total protein and total bilirubin in between the 2 groups was statistically insignificant. The study also found that the difference in AST, ALT and LDH was statistically significant between HIE stage 1 and stage 2 (p&lt;0.5), between HIE stage 1 and stage 3 (p&lt;0.5) but insignificant between HIE stage 2 and stage 3 (p&gt;0.5).Conclusions: The present study showed that the serum levels of hepatic enzymes were higher in full term neonates with perinatal asphyxia than full term neonates without perinatal asphyxia at the age of 72 hours. The enzyme levels showed an increasing trend with increasing severity of HIE.

IL-6 and IL-10 Levels, Rather Than Viral Load and Neutralizing Antibody Titers, Determine the Fate of Patients With Severe Fever With Thrombocytopenia Syndrome Virus Infection in South Korea.

Severe fever with thrombocytopenia syndrome (SFTS) is a new tick-borne viral disease, and most SFTS virus (SFTSV) infections occur via bites from the tick Haemaphysalis longicornis; however, SFTSV transmission can also occur through close contact with an infected patient. SFTS is characterized by acute high fever, thrombocytopenia, leukopenia, elevated serum hepatic enzyme levels, gastrointestinal symptoms, and multiorgan failure and has a 16.2 to 30% mortality rate. In this study, we found that age, dyspnea rates, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase, multiorgan dysfunction score (MODS), viral load, IL-6 levels, and IL-10 levels were higher in patients with fatal disease than in patients with nonfatal disease during the initial clinical course of SFTS. In addition, we found that IL-6 and IL-10 levels, rather than viral load and neutralizing antibody titers, in patients with an SFTSV infection strongly correlated with outcomes (for severe disease with an ultimate outcome of recovery or death).

CXCL8 expression and methylation are correlated with anthropometric and metabolic parameters in childhood obesity

Childhood obesity is a global and increasing health issue. Inflammation and dysregulated adipose tissue secretion are common findings in obesity and have been related to poor metabolic function. Given that DNA methylation impacts gene expression and is responsive to environmental changes, we aimed, in addition to characterize the patients in anthropometric and biochemical terms, to determine the expression of cytokines and adipokines, assess the methylation on regulatory regions of the genes that code for these molecules, and investigate the association of the expression and gene methylation with anthropometric and biochemical parameters in childhood obesity. Obese children present dyslipidemia, dysregulated serum levels of adipokines and their ratios, altered leukocytic expression of cytokines, and higher methylation at the CXCL8 promoter as compared to the control group. However, no significant results were observed in the fasting plasma glucose levels or the methylation of TGFB1, LEP, and the enhancer region of ADIPOQ. We also found negative correlations of CXCL8 expression with anthropometric and biochemical parameters, and positive correlation of CXCL8 promoter methylation and the serum levels of hepatic enzymes. Our results indicate that changes in metabolic parameters observed in childhood obesity are associated with the expression of adipokines and cytokines, and the methylation status at the CXCL8 promoter. CXCL8 may be a key factor for these alterations, as it correlates with many of the parameters assessed in the present study.
