Ciprofloxacin Affect Sperm Quality and Induced Testicular and Hepatic Injury in Male Mice

Ciprofloxacin (CPFx) is one of a second-generation fluoroquinolones antibiotic and is prescribed a lot for curing bacterial infection. The aim of this study was to investigate of impact CPFx on sperm characteristics, liver DNA and histological structure of liver and testes. Twenty-four male mice aged 7-10 weeks were divided into three groups of eight. The first group (control) was given distilled water. The second and third groups received CPFx with doses 500 and 750 mg/kg respectively. All treatments were administrated orally for 14 days. Three untreated females were put with one treated male for mating. At the end of dosing period, mice were killed, testes and liver were removed and weighed. Sperm parameters, testosterone level and liver DNA were measured. Histopathology of liver and testes was carried out. The results showed that CPFx significantly affected liver DNA, sperm motility and morphology as well as it caused histopathological alterations of hepatic and testicular tissues. Moreover, it led to a significant elevation in the percentage of dead fetuses and also deformity fetuses. The results indicate that CPFX has detrimental effects on sperm quality, liver DNA and histological structure of testes and liver; therefore, it should be used with great caution

Hepatocyte-specific METTL3 ablation by Alb-iCre mice (GPT), but not by Alb-Cre mice (JAX), resulted in acute liver failure (ALF) and postnatal lethality.

In 2019, to examine the functions of METTL3 in liver and underlying mechanisms, we generated mice with hepatocyte-specific METTL3 homozygous knockout (METTL3Δhep) by simultaneously crossing METTL3fl/fl mice with Alb-iCre mice (GPT) or Alb-Cre mice (JAX), respectively. In this study, we explored the potential reasons why hepatocyte-specific METTL3 homozygous disruption by Alb-iCre mice (GPT), but not by Alb-Cre mice (JAX), resulted in acute liver failure (ALF) and then postnatal lethality. Mice with hepatocyte-specific METTL3 knockout were generated by simultaneously crossing METTL3fl/fl mice with Alb-iCre mice (GPT; Strain No. T003814) purchased from the GemPharmatech Co., Ltd., (Nanjing, China) or with Alb-Cre mice (JAX; Strain No. 003574) obtained from The Jackson Laboratory, followed by combined-phenotype analysis. The publicly available RNA-sequencing data deposited in the NCBI Gene Expression Omnibus (GEO) database under the accession No.: GSE198512 (postnatal lethality), GSE197800 (postnatal survival) and GSE176113 (postnatal survival) were mined to explore the potential reasons why hepatocyte-specific METTL3 homozygous deletion by Alb-iCre mice (GPT), but not by Alb-Cre mice (JAX), leads to ALF and then postnatal lethality. Firstly, we observed that hepatocyte-specific METTL3 homozygous deficiency by Alb-iCre mice (GPT) or by Alb-Cre mice (JAX) caused liver injury, abnormal lipid accumulation and apoptosis. Secondly, we are surprised to find that hepatocyte-specific METTL3 homozygous deletion by Alb-iCre mice (GPT), but not by Alb-Cre mice (JAX), led to ALF and then postnatal lethality. Our findings clearly demonstrated that METTL3Δhep mice (GPT), which are about to die, exhibited the severe destruction of liver histological structure, suggesting that METTL3Δhep mice (GPT) nearly lose normal liver function, which subsequently contributes to ALF, followed by postnatal lethality. Finally, we unexpectedly found that as the compensatory growth responses of hepatocytes to liver injury induced by METTL3Δhep (GPT), the proliferation of METTL3Δhep hepatocytes (GPT), unlike METTL3Δhep hepatocytes (JAX), was not evidenced by the significant increase of Ki67-positive hepatocytes, not accompanied by upregulation of cell-cycle-related genes. Moreover, GO analysis revealed that upregulated genes in METTL3Δhep livers (GPT), unlike METTL3Δhep livers (JAX), are not functionally enriched in terms associated with cell cycle, cell division, mitosis, microtubule cytoskeleton organization, spindle organization, chromatin segregation and organization, and nuclear division, consistent with the loss of compensatory proliferation of METTL3Δhep hepatocytes (GPT) observed in vivo. Thus, obviously, the loss of the compensatory growth capacity of METTL3Δhep hepatocytes (GPT) in response to liver injury might contribute to, at least partially, ALF and subsequently postnatal lethality of METTL3Δhep mice (GPT). These findings from this study and other labs provide strong evidence that these phenotypes (i.e., ALF and postnatal lethality) of METTL3Δhep mice (GPT) might be not the real functions of METTL3, and closely related with Alb-iCre mice (GPT), suggesting that we should remind researchers to use Alb-iCre mice (GPT) with caution to knockout gene in hepatocytes in vivo.

Protective Effect of Parsley Oil on the Histological Structure of Liver in Adult Mice Induced by Cadmium Chloride

Toxicity evaluation of Dolichandrone serrulata flower extract on vital and reproductive organs in adult male rats.

Although Dolichandrone serrulata flower (DSF) aqueous extract has been shown to possess pharmacological properties, its systemic toxicity has still to be evaluated. The present study aimed to investigate the sub-chronic toxicity effect of DSF extract on biochemical parameters and histological structures of liver, kidney, testis, and epididymis plus vas deferens. Adult male rats were administered DSF at 100, 300, and 600 mg/kgBW via oral gavage for 48 consecutive days while control rats received distilled water. At the end of the experiment, blood, liver, kidney, testis, and epididymis plus vas deferens samples were collected to determine any changes to serum biochemical components including ALT, ALP, and creatinine levels and histological structures. The results revealed no significant difference in body weight and food or water consumption between control and the DSF-treated groups. It was found that DSF significantly increases the weight of epididymis plus vas deferens, while the kidney and liver showed a decrease in the high dose group (P value < 0.05). Histological changes in these vital and reproductive tissues including fibrosis were not observed after administration but ALT, ALP, and creatinine levels were significantly altered in the treated groups (P value < 0.05). These altered levels, however, were still within normal ranges. In conclusion, these findings demonstrated that D. serrulata flower extract had no sub-chronic toxicity on vital and reproductive structures but slightly altered some liver and kidney functions.

Oral administration of Arctium tomentosum Mill. CO2-extract alleviates the diet induced metabolic disorder in mice

Nowadays, the metabolic disorder exists along with other pathological conditions, such as hyperglycemia, hypertriglyceridemia, hypercholesterolemia and gain of the excess abdominal fat. It has negative impact on human health, but especially the liver health. The present work was designed to study the liver supporting effect of ATE on mice with high-fructose and high-sucrose diet induced metabolic disorder. The study was conducted on mice, divided into following groups: NC; untreated MD; group with MD treated by ATE at the doses 50, 200 and 400 mg/kg respectively. As a result, the liver supporting effect of ATE at the doses of 200 and 400 mg/kg was shown in the values of body weight, relative weight of the liver, kidneys and epidydimal fat. The same was observed in plasma biochemistry, in which groups treated with ATE showed normal levels of triglycerides, total and low-density cholesterol, ALT, AST. The treatment by 400 mg/kg ATE significantly inhibited the lipid accumulation and hepatocytes degeneration in the liver histological structure. In conclusion these findings provide the potential therapeutic usefulness into the effects of ATE in the treatment of metabolic disorder. Furthermore, it suggests that ATE has hepatoprotective effect which is conducted via its antioxidant properties.

Ameliorative potential role of Rosmarinus officinalis extract on toxicity induced by etoposide in male albino rats.

The present work was showed to assess the effect of administration of rosemary extract on etoposide-induced toxicity, injury and proliferation in male rats were investigated. Forty male albino rats were arranged into four equal groups. 1st group, control; 2nd group, etoposide; 3rd group, co-treated rosemary & etoposide; 4th group, rosemary alone. In comparison to the control group, etoposide administration resulted in a significant increase in serum ALT, AST, ALP, total bilirubin, total protein, and gamma GT. In contrast; a significant decrease in albumin level in etoposide group as compared to G1. G3 revealed a significant decrease in AST, ALT, ALP, total protein and total bilirubin levels and a significant rise in albumin level when compared with G2. Serum levels of urea, creatinine, potassium ions, and chloride ions significantly increased; while sodium ions were significantly decreased in G2 when compared with G1. Also, there was an increase of MDA level for etoposide treated group with corresponding control rats. However, there was a remarkable significant decrease in SOD, GPX and CAT levels in G2 as compared to G1. There was a significant increase in serum hydrogen peroxide (H2O2) and Nitric oxide (NO) levels in group treated with etoposide when compared to control group. It was noticeable that administrated by rosemary alone either with etoposide had not any effect on the levels of H2O2 and Nitric oxide. Serum level of T3 and T4 was significantly increased in etoposide-administered rats in comparison with G1. The administration of rosemary, either alone or with etoposide, increased the serum levels of T3 and T4 significantly when compared to control rats. The gene expression analysis showed significant downregulation of hepatic SOD and GPx in (G2) when compared with (G1). The treatment with rosemary extract produced significant upregulation of the antioxidant enzymes mRNA SOD and GPx. MDA gene was increased in (G2) when contrasted with (G1). Treatment of the etoposide- induced rats with rosemary extract delivered significant decrease in MDA gene expression when compared with etoposide group. Rats treated with etoposide showed significant decline in hepatic Nrf2 protein expression, when compared with G1. While, supplementation of Etoposide- administered rats with the rosemary produced a significant elevation in hepatic Nrf2 protein levels. Additionally, the liver histological structure displayed noticeable degeneration and cellular infiltration in liver cells. It is possible to infer that rosemary has a potential role and that it should be researched as a natural component for etoposide-induced toxicity protection.

Effects of fucoidan on growth performance, immunity, antioxidant ability, digestive enzyme activity, and hepatic morphology in juvenile common carp (Cyprinus carpio)

Fucoidan with its excellent biological activities such as growth promotion, antioxidant and strong immunity, is widely used in animal production. The present study was conducted to investigate the influences of feeding fucoidan on growth performance, biochemical indices, immunity, the antibacterial ability of plasma, the digestive enzyme activity of the intestine, antioxidant capacity, and the histological structure of liver in juvenile common carp. Five experimental diets added with 0 (Diet 1), 500 (Diet 2), 1,000 (Diet 3), 1,500 (Diet 4), and 2,000 (Diet 5) mg/kg fucoidan were fed to triplicate groups of 30 fish (35.83 ± 0.24 g) respectively for 8 weeks. The results showed that fish fed diets with a fucoidan supplementation of 1,666.67–1,757 mg/kg might have the best growth performance (p&amp;lt; 0.05). The levels of plasma total protein (TP) and albumin (ALB) in Diet 3, Diet 4, and Diet 5 were higher than those in Diet 1 and Diet 2 (p&amp;lt; 0.05). Moreover, the contents of plasma C3, LYZ, and IgM; the antibacterial ability of serum; and the activity of SOD, CAT, POD, and GPX in the liver, and ACP, AKP, LPS, AMS, and TRY in the intestine significantly improved; the contents of LPO and MDA in the liver were notably decreased in diets with fucoidan supplement (p&amp;lt; 0.05). Furthermore, the activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and the contents of total bilirubin (TB) and glucose (Glu) in Diet 5 were the highest among the groups. Meanwhile, proinflammatory factors (plasma IL-6 and IL-1β) had a higher expression, but anti-inflammatory factors (plasma IL-1) had a lower expression in Diet 5 (p &amp;gt; 0.05). It indicated that a higher dose (2,000 mg/kg) of fucoidan may induce inflammation and metabolic disorders. Interestingly, histological results of liver also indicated that dietary fucoidan intake in certain amounts (500–1,500 mg/kg) could ameliorate hepatic morphology, but the high dosage (2,000 mg/kg) probably damaged the liver. To the best of our knowledge, this is the first study on the application of fucoidan as a functional additive to juvenile common carp. The results of the present study can be used to guide the application of fucoidan in healthy aquaculture and can further reveal the effect and mechanism of fucoidan on the nutritional physiology of aquatic animals.

Capitata has a treated effect of the damage caused by diabetes.

Impact of Spirulina Supplementation on Some Immune and Biochemical Parameters of Nile Tilapia Under Cold Stress

Climatic change is a grave and growing threat to natural systems and aquatic species. Cold stress has caused a great worldwide economic loss in aquacultures worldwide. This study aimed to evaluate the effect of dietary Spirulina (Arthrospira platensis) on immunobiochemical parameters, antioxidants, some metabolic gene expressions, and histological structure of liver and kidney of Nile tilapia (Oreochromis niloticus) under cold stress. One hundred and sixty Nile tilapia were divided into eight groups (10 fish per aquarium) in two replicates. The first four groups were maintained at 26 °C whereas, the rest were subjected to 17 °C cold stress. They were fed three spirulina-contained diets (0.75, 1.5, and 3%) and a control diet for three weeks. Blood and tissue samples were collected from all groups after exposure to cold stress. The results of the cold-stressed group that fed control diet showed a significant decreases in the serum level of cortisol, catalase, superoxide dismutase, phagocytic activity, tumor necrotic factor α, Interleukin 1β, Interleukin 6, and Interleukin 17. Also, it explored a significant increased serum level of heat shock protein 70, glucose, Interleukin 10, and malondialdehyde, beside up-regulation of Phosphoenolpyruvate carboxykinase 1, and mitochondrial transcription factor A genes. In addition to, alteration of liver and kidney biomarkers with severe histopathological perturbations of liver and kidney were detected. Dietary Spirulina supplementation at 0.75% during cold stress ameliorate the immune and antioxidant status, biochemical parameters and protecting the integrated tissue architecture from oxidative damage of Nile tilapia.

Down-regulation of complement genes in lipopolysaccharide-challenged zebrafish (Danio rerio) larvae exposed to Indonesian propolis.

Although propolis has been reported for having anti-inflammatory activities, its effects on complement system has not been much studied. This research was conducted to find out the effects of Indonesian propolis on the expression levels of C3, C1r/s, Bf, MBL, and C6 in zebrafish larvae which were induced by lipopolysaccharide (LPS). Counting of macrophages migrating to yolk sac and liver histology were carried out. Larvae were divided into four groups: CON (cultured in E3 medium only), LPS (cultured in a medium containing 0.5 μg/L LPS), LPSIBU (cultured in a medium containing LPS, and then treated with 100 μg/L ibuprofen for 24 hours), and LPSPRO (cultured in a medium containing LPS, and then immersed in 14,000 μg/L propolis for 24 hours) groups. The results showed that complement gene expression in larvae from the LPSIBU and LPSPRO groups were generally lower than in larvae from the LPS group. The number of macrophage migrations to the yolk in the LPSPRO group was also lower than in the LPS group. Histological structure of liver in all groups were considered normal. This study shows that Indonesian propolis has the potential to be used as an alternative to the substitution of NSAIDs.

Quercetin potentiates the hepatoprotective effect of sildenafil and/or pentoxifylline against intrahepatic cholestasis: Role of Nrf2/ARE, TLR4/NF-κB, and NLRP3/IL-1β signaling pathways

AimIntrahepatic cholestasis is a common pathological condition of several types of liver disorders. In this study, we aimed to investigate the regulatory effects of quercetin (QU) on selected phosphodiesterase inhibitors against alpha-naphthyl isothiocyanate (ANIT)-induced acute intrahepatic cholestasis. MethodsCholestasis was induced in Wistar albino rats by ANIT as a single dose (60 mg/kg; P·O.). QU (50 mg/kg, daily, P·O.), sildenafil (Sild; 10 mg/kg, twice daily, P·O.), and pentoxifylline (PTX; 50 mg/kg, daily, P.O.) were evaluated either alone or in combinations for 10 days for their antioxidant, anti-inflammatory, and anti-pyroptotic effects. ResultsANIT produced a prominent intrahepatic cholestasis as evidenced by a significant alteration in liver functions, histological structure, inflammatory response, and oxidative stress biomarkers. Furthermore, up-regulation of NF-κB-p65, TLR4, NLRP3, cleaved caspase-1, IKK-β, and IL-1β concurrently with down-regulation of Nrf-2, HO-1, and PPAR-γ expressions were observed after ANIT. QU, Sild, or PTX treatment significantly alleviated the disturbance induced by ANIT. These findings were further supported by the improvement in histopathological features. Additionally, co-administration of QU with Sild or PTX significantly improved liver defects due to ANIT as compared to the individual drugs. SignificanceCombined QU with Sild or PTX exhibited promising hepatoprotective effects and anti-cholestatic properties through modulation of Nrf2/ARE, TLR4/NF- κB, and NLRP3/IL-1β signaling pathways.

Dysfunctions of liver and behavioural disorders of females rats suffering from malnutrition: Physiological and histological information as a model of animal anorexia nervosa disease

Anorexia nervosa disease is an eating deficiency that occurs around 1 per 100 individuals. The present study was conducted to assess the effects of malnutrition (animal anorexia nervosa models) via removing certain elements from food on liver functions and behaviours of female rats. Eighteen Females of rats were divided into three groups: Control, in which food intake quantity was 25 g /day, moderately food-restricted Group, in which food intake quantity was 15 g /day, and severe food-restricted Group, in which food intake quantity was 5 g /day, for 90 days. Physiological parameters, liver histopathological analysis, and the behaviour measurement by multiple T maze tests were examined. All food-restricted groups observed a significant increase (p&lt;0.05) in aminotransferase, Malondialdehyde and lactate dehydrogenase levels. Antioxidant activity, acid phosphatase, hepatic protein, glycogen and serotonin levels were significantly (p&lt;0.05) decreased in all food-restricted groups. The hyperactivity behaviour appeared as a feature of restricted rats. Histopathological examinations indicated a marked alteration in the hepatocyte with features of autophagy in the restricted Group. Food-restriction (animal anorexia nervosa model) in rats caused disorders in hepatic aminotransferase and serotonin levels and antioxidant activity in addition to hyperactivity behaviours with changes in the liver histological structure in the restricted Group. The study focused on the effect deficiency in essential nutrients needed by the body may have side effects on liver functions and behavioural activity of the animals linked with food searching was measured by multiple T maze tests.

Neuro-hepatopathological changes in juvenile Oreochromis niloticus exposed to sublethal concentrations of commercial herbicides

The current study estimates the impact of different common herbicides on antioxidant defenses and histological structure of liver and spinal cord of juvenile tilapia. Eighty-four fish were divided into seven groups: group 1 fish acted as controls and the remaining fish were exposed to sublethal concentrations of acetochlor, bispyribac-sodium, bentazon, bensulfuron-methyl, halosulfuron-methyl, or quinclorac at sublethal concentrations 2.625, 0.800, 36.00, 2.50, 1.275, and 11.250 mg/l, respectively, for 96 h. Antioxidant parameters changed in response to some test herbicides and the greatest effects were caused by exposure to acetochlor and quinelorac for all antioxidant measurements. Prominent histological changes in liver tissue included loss of liver architecture and the appearance of fatty liver cells, necrotic areas, foci of leukocytic infiltration and many apoptotic cells. The most obvious changes in the spinal cord in all treated fish were degradation of myelinated white matter fibers with the emergence of empty spaces, large aggregation of pyknotic neuroglial nuclei, and damaged areas in the dorsal horn of gray matter. Collectively, the harmful effect of tested herbicides on antioxidant capacity and significant alterations in histological structures of liver and spinal cord of Oreochromis niloticus.

Changes in Histological Structure, Interleukin 12, Smooth Muscle Actin and Nitric Oxide Synthase 1. and 3. Expression in the Liver of Running and Non-Running Wistar Rats Supplemented with Bee Pollen or Whey Protein.

Introduction: Bee pollen is a natural substance obtained from flowers by bees. It is a rich source of protein, vitamins and minerals. It can be used as a dietary supplement. Bee pollen has been investigated for the treatment of some diseases with promising potential. It can be helpful in supportive therapy for dyslipidemia, metabolic syndrome, diabetes type 2, as well the prevention and control of coronary heart disease and myocardial infarction. Whey protein is a rich source of amino acids. It is a basic dietary supplement for many athletes, both professional and amateur. It stimulates muscle growth and provides nutrition for cachectic patients. Aim of the study: The objective of the study was to assess the impact of dietary supplementation of bee pollen or whey protein on the Wistar rat liver histological structure and expression of interleukin 12, smooth muscle actin and nitric oxide synthases among running and non-running rats. Material and methods: Thirty male Wistar rats were divided into six equal groups, three running and three non-running. Among both there was one control, one supplemented with bee pollen and one receiving whey proteins. After 8 weeks, all animals were decapitated and their livers were collected. Five micrometer thick slides were prepared and used for classical histological staining and immuno-histochemistry. ImageJ image analysis software was used to measure optical density and immunohistochemistry profile coverage. Results: Among all groups, morphology of liver was similar. In the running control group, expression of interleukin-12 (IL-12) was decreased as well as expression of endothelial nitric oxide synthase (eNOS) in a group of bee pollen supplemented rats. No significant changes in α- smooth muscle actin (α-SMA) expression was observed. Conclusions: Bee pollen is proving to be a questionable choice for athletes as an alternative to whey protein. Bee pollen supplementation affects hepatocyte cellular activity and has hepatoprotective effects. Whey protein performs worse in this regard. Lower antioxidant properties were found in groups supplemented with bee pollen than with whey protein.

The optimal dietary taurine supplementation in zero fish meal diet of juvenile snakehead fish (Channa striata)

The most common alternative protein sources are plant-based proteins such as soybean meal but one of the limitations is taurine deficiency that can be especially detrimental for carnivorous fish. This study was to determine the important roles of dietary taurine on the growth performance, feed utilization and body composition of juvenile snakehead fish with an initial weight of 4.66–4.71 g/fish. Five test diets were investigated, using various taurine supplementation levels and both isonitrogenous and isoenergetic formulas: 1)control (fish meal inclusion); 2)zero fish meal diet (ZF) without taurine supplementation (T0); 3) ZF with taurine supplementation at 0.5% (T0.5); 4) ZF with taurine supplementation at 1.0% (T1.0); 5) ZF with taurine supplementation at 1.5% (T1.5). Fish were fed with five different dietary taurine levels for 60 days. Weight gain (WG), average daily gain (ADG) and specific growth rate (SGR) were higher in the control group of fish, followed by the T0.5 and T1.0 group but the lowest level was observed in fish fed the T0 and T1.5 (p < 0.05). The statistical results of Survival rate (SR), feed conversion ratio (FCR) and protein efficiency ratio (PER) were not significantly different (p > 0.05) among all experimental groups, whereas fish fed diet T0.5 and T1.0 had good trend in FCR and PER value similar to the control group. Dietary taurine might not affect on whole-body composition in juvenile snakehead fish (p > 0.0). Taurine accumulation in fish whole body and the liver both showed the increasing trends varying supplementation levels in each experimental diet. In the current study, taurine supplementation had no observable effects on the histological structures of liver and distal intestines of snakehead fish. This phenomenon indicated that the taurine supplementation at 0.5% in the plant protein-based diet (ZF) cloud be improved the growth performance and feed utilization of juvenile snakehead fish. Leading to, this is a positive sign of a possibility to reduce feed cost by completely taking fish meal out of a future commercial aquafeed for better aquaculture business sustainability.

Evaluation of long-term consumption of soft drinks on liver function in laboratory female rats

Consumption of soft drinks (SDs) has increased in recent years. Soft drinks contain a collection of chemical compounds can produce multiple side effects. This work aimed to inspect the impacts of long-term consumption of SDs on liver function, antioxidant and oxidative biomarker, body weight, lipid profile and liver histological structure in female albino rats. Twenty-four female albino White rats (Rattus norvigicus) were randomly assigned to six groups of four animals: two control groups (groups 1-2) were fed regular pellet; Coca-Cola group (groups 3-4) were fed with standard pellet diet and given Coca Cola (2 ml) once a day; and Seven up groups (groups 5-6) were fed with standard pellet diet and given Seven up (2 ml) once a day. The treatment continued for two weeks and four months. All treatments were administered by oral gavage. Cardiac puncture technique was used for taken blood samples after 2 weeks and 3 months for measurement of liver function tests, malondialdehyde (MDA), glutathione (GSH) and lipid profile, in addition to the histological study for the liver tissue. ALAT, ASAT and ALP activity considerably elevated (p≤0.05) in animal dosed with Coca Cola and Seven up daily for 4 months. GSH significantly decrease (p≤0.05) in animal dosed with Coca Cola for 4 months. MDA was significantly increase (p≤0.05) in animal dosed with Coca Cola and Seven up for 4 months. Body weight gains significantly elevated in the treated groups for 4 months compared with the control and the other groups. Total cholesterol, TG, VLDL-C and LDL-C was increased significantly in the groups dosed with Coca Cola and Seven up for 2 weeks and 4 months compared with other groups. While the HDL-C showed a significant reduction in the groups dosed with Coca Cola and Seven up for 2 weeks and 4 months. Histopathological study revealed changes in the liver of groups treated with Cola and Seven up for 4 months represented by the appearance of a dilated and congested portal vein and ballooning degeneration of hepatocytes. In conclusions, chronic consumption of soft drinks has harmful effects on liver function and a reason for exposure to fatty liver disease.

Histopathological Study of Streptozotocin Induced Liver Regeneration of Wistar Mice after Administration of Pumpkin Leaf Ethanol Extract

This study aims to prove that the ethanol extract of pumpkin leaf can improve the liver histological structure of Wistar rats streptozotocin and find out the effective dose in regenerating the liver cells of Wistar rats. Wistar rats were divided into six groups so that each group has five replications. The control group was not given the extract, and the treatment group was administered the extract with three doses of 125 mg/kg BW, 150 mg/kg BW, and 175 mg/kg BW which were carried out for three weeks. Rats were then sacrificed and the liver organs were taken for the histopathology preparations with Hematoxylin-Eosin staining (HE). The results showed fatty degeneration and necrosis of the livers. The results of the Mann-Withney test analysis showed that there was a significant difference in liver histopathology scoring from each treatment group. Ethanol extract of pumpkin leaves at a dose of 150 mg/kg BW gave an effect on the regeneration of liver cells of Wistar rats with a damage score of 1.4 and had no effective dose

Raphani Semen (Raphanus sativus L.) Ameliorates Alcoholic Fatty Liver Disease by Regulating De Novo Lipogenesis.

In this study, we investigated the pharmacological effect of a water extract of Raphani Semen (RSWE) on alcoholic fatty liver disease (AFLD) using ethanol-induced AFLD mice (the NIAAA model) and palmitic acid (PA)-induced steatosis HepG2 cells. An RSWE supplement improved serum and hepatic triglyceride (TG) levels of AFLD mice, as well as their liver histological structure. To explore the molecular action of RSWE in the improvement of AFLD, we investigated the effect of RSWE on four major pathways for lipid homeostasis in the liver: free fatty acid transport, lipogenesis, lipolysis, and β-oxidation. Importantly, RSWE decreased the mRNA expression of de novo lipogenesis-related genes, such as Srebf1, Cebpa, Pparg, and Lpin1, as well as the protein levels of these factors, in the liver of AFLD mice. That these actions of RSWE affect lipogenesis was confirmed using PA-induced steatosis HepG2 cells. Overall, our findings suggest that RSWE has the potential for improvement of AFLD by inhibiting de novo lipogenesis.
