Assessment of Antioxidant and Hepatoprotective Effects of Kappaphycus alvarezii (Doty) Doty ex Silva Against Carbon Tetrachloride-Induced Liver Injury in Rats

Kappaphycus alvarezii (Doty) Doty ex Silva, commonly known as red algae, holds economic significance as a primary source of κ-carrageenan, which exhibits promising medicinal and therapeutic properties. This study aims to assess the antioxidant potential as well as hepatoprotective activity of the ethanolic extract of K. alvarezii (EEKA). The assays utilised to determine the antioxidant properties of EEKA were total phenolic content (TPC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging. In addition, the ability of EEKA to ameliorate experimentally induced liver injury in Sprague-Dawley rats caused by carbon tetrachloride (CCl4) was evaluated. The biochemical assays involved measuring liver marker enzymes (AST and ALT) in serum as well as determining the levels of reduced glutathione (GSH), lipid peroxidation (LPO) via malondialdehyde, catalase (CAT), and glutathione S-transferase (GST) in liver homogenates. The TPC and DPPH radical scavenging activity of EEKA demonstrated relatively low antioxidant properties compared to standard references. However, CCl4-induced groups exhibited significantly increased levels of AST and ALT, along with depletion of antioxidant status (GSH, CAT, and GST) indicated by LPO. Pretreatment with EEKA resulted in slightly decreased liver marker enzyme activity and LPO, coupled with an increase in antioxidant status. These findings suggest that EEKA contains active principles capable of counteracting the hepatotoxic effects induced by CCl4.

Antidiabetic effects of aqueous leaf extract of Vernonia amygdalina on serum liver markers in streptozotocin-induced diabetic albino Rats: a new data to support its Anti-diabetic effect

BackgroundNumerous plants have been explored for their potential antidiabetic properties, and Vernonia amygdalina (VA) stands among them. This study aims to investigate the antidiabetic activities of VA and validate its efficacy.MethodsAn aqueous extract of Vernonia amygdalina leaves was obtained through maceration. The antidiabetic effects of this plant extract were evaluated in vivo using diabetic model rats. Albino Wistar rats were induced into a diabetic state through intraperitoneal injection of streptozocin and subsequently treated with an optimal dose of 250 mg/kg aqueous extract of VA over a 21-day period. Parameters such as body weight, blood glucose levels, and serum marker enzymes were measured.ResultsThe results demonstrated a significant reduction (p < 0.05) in the glucose levels of streptozocin-induced diabetic rats following treatment with VA extract, highlighting its potential as an antidiabetic agent that performed comparably to the reference drug, glimepiride. Additionally, a significant increase (p < 0.05) in the body weight of the treated diabetic rats was observed. Aqueous extracts also significantly (p < 0.05) altered the serum concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in a manner similar to the glimepiride-treated group.ConclusionThis study affirms the anti-diabetic effects of the aqueous extract of Vernonia amygdalina in streptozotocin-induced diabetic rats and suggests that the extract holds promise as an important phytomedicine for the development of more effective treatments for diabetes.

Testosterone with Silymarin Improves Diabetes-obesity Comorbidity Complications by Modulating Inflammatory Responses and CYP7A1/ACC Gene Expressions in Rats.

The co-morbidity of DMOB has become increasingly problematic among the world's population because of a high-calorie diet and sedentary lifestyle. DMOB is associated with lower testosterone (TN) levels, the male sex hormone. The phytochemical compound silymarin (SN) exerts antidiabetic activity by modifying β-cells and anti-obesity activity by inhibiting adipogenesis by methylxanthine. The goal of this study was to find out how well testosterone (TN) with silymarin (SN) protects against oxidative stress and inflammation in the liver of the experimental rats with type 2 diabetes (T2D) and obesity (DMOB). The present study evaluates the efficacy of TN and SN combination (TNSN) on the levels of the potential parameters, such as body mass, serum marker enzymes, fasting glucose levels, HbA1c levels, lipid profile, enzymatic and non-enzymatic antioxidants, proinflammatory cytokines, gene expression pathways, and histopathology in a DMOB comorbidity rat model. Male Sprague-Dawley (SD) rats were fed a high-fat diet (HFD) for 20 weeks with an administration of a single dose of streptozotocin (STZ) i.p. injection (30 mg/kg) on the 9th week of the study. The procedure was to develop the DMOB co-morbidity model in the experimental animals. Co-treatment of TN and SN administration were followed throughout the experiment. Rats were sacrificed after overnight fasting to collect serum and liver tissue samples. Samples were analyzed using a clinical chemistry automated analyzer, spectrophotometry, and quantitative real-time PCR (qPCR) methods and protocols. Analyses of body mass changes, serum marker enzymes, fasting glucose levels, HbA1c levels, lipid profiles, enzymatic and non-enzymatic antioxidants, TNF-α, IL-6, adiponectin, CYP7A1, ACC expression pathways, and histopathology showed significant abnormal levels (P ≤ 0.05) in the pathological group. These were efficiently treated to normal by the administration of TNSN. These results concluded that TNSN exerted protective efficacy against the liver abnormalities in the co-morbidity of the DMOB rat model.

Hepatoprotective and Antioxidant Activity of Stem and Leaves Parts of Cissus woodrowii (Stapf ex Cooke) Santapau

The contemporary investigation aimed to assess the hepatoprotective potential of Cissus woodrowii (Stapf ex Cooke) Santapau against carbon tetrachloride-induced hepatotoxicity. Through evaluating antioxidant levels in liver tissues and blood marker enzymes, it was observed that administration of the plant extract at doses of 200 and 400 mg/kg significantly mitigated liver damage caused by carbon tetrachloride. The study found that carbon tetrachloride-induced reductions in total protein, catalase, glutathione (GSH), and superoxide dismutase (SOD) levels, while increasing levels of alkaline phosphatase, alanine aminotransferase, total bilirubin, lipid peroxidation, and aspartate aminotransferase. However, rats treated with varying doses of the plant extract exhibited restoration towards normal levels of serum marker enzymes and antioxidants, contrasting with those solely exposed to carbon tetrachloride. These findings collectively suggest that C. woodrowii (Stapf ex Cooke) Santapau possesses antioxidant properties and exerts a hepato-protective effect against CCl4-induced liver impairment in rats.

Thymoquinone protects thioacetamide-induced chronic liver injury by inhibiting TGF-β1/Smad3 axis in rats.

Chronic liver injury due to various etiological factors results in excess secretion and accumulation of extracellular matrix proteins, leading to scarring of liver tissue and ultimately to hepatic fibrosis. If left untreated, fibrosis might progress to cirrhosis and even hepatocellular carcinoma. Thymoquinone (TQ), an active compound of Nigella sativa, has been reported to exhibit antioxidant, anti-inflammatory and anticancer activities. Therefore, the effect of TQ against thioacetamide (TAA)-induced liver fibrosis was assessed in rats. Fibrosis was induced with intraperitoneal administration of TAA (250 mg/kg b.w.) twice a week for 5 weeks. TQ (20 mg/kg b.w.) and silymarin (50 mg/kg b.w.) were orally administered daily for 5 weeks separately in TAA administered groups. Liver dysfunction was reported by elevated liver enzymes, increased oxidative stress, inflammation and fibrosis upon TAA administration. Our study demonstrated that TQ inhibited the elevation of liver marker enzymes in serum. TQ administration significantly increased antioxidant markers, such as superoxide dismutase, catalase, glutathione, glutathione peroxidase and glutathione reductase in the liver tissue of rats. Further, TQ significantly attenuated liver fibrosis, as illustrated by the downregulation of TAA-induced interleukin-β, tumour necrosis factor-α, inducible nitric oxide synthase and fibrosis markers like transforming growth factor-β (TGF-β), α-smooth muscle actin, collagen-1, Smad3 and 7. Therefore, these findings suggest that TQ has a promising hepatoprotective property, as indicated by its potential to effectively suppress TAA-induced liver fibrosis in rats by inhibiting oxidative stress and inflammation via TGF-β/Smad signaling.

Antioxidant and Protective Effect of Ocimum basilicum Seeds Extract on Renal Toxicity Induced by Carbon Tetrachloride in Rats.

Basil (Ocimum basilicum L.) is distributed worldwide and used in the food, pharmaceutical, and cosmetic industries. Most applications are for the herb basil, recently the basil seeds have also been used commercially; however, little is known about the nutritional and functional properties of the seeds. The present study aimed to investigate a possible protective effect of the methanol extract of O. basilicum seeds (MEOB), based on its phytochemical content, against kidney toxicity induced by CCl4 in adult rats. A single dose of CCl4 was used to induce oxidative stress in rats, which was demonstrated by a significant rise of serum enzyme markers. MEOB was administrated for 15 consecutive days (200 mg/kg body weight) to Wistar rats before CCl4 treatment and the effects on serum urea, creatinine, and uric acid, as well as the kidney superoxide dismutase, catalase, glutathione peroxidase, and glutathione activity and thiobarbituric acid reactive substances and protein carbonyl (PCO) levels were evaluated. In addition, histopathological examinations of kidneys were performed. In the positive control group, CCl4 induced an increase in serum biochemical parameters and triggered oxidative stress in the kidney. MEOB (200 mg/kg BW) resulted in significant reduction of CCl4-elevated levels of kidney markers, urea and creatinine, and a significant increase of uric acid compared with the CCl4-only group. In addition, MEOB pretreatment resulted in a significant reduction in lipid peroxidation and PCO levels in renal tissue compared with CCl4-exposed group. MEOB definitely could prevent the development of pathological changes in the kidneys. Overall, we conclude that MEOB is effective in protecting renal function from CCl4 toxicity.

Sinensetin mitigates polystyrene nanoplastics induced hepatotoxicity in albino rats: A biochemical and histopathological study

Polystyrene nanoplastics (PS-NPs) are environmental pollutants that induce oxidative stress (OS) in multiple organs particularly, liver. Sinensetin (SNS) is a naturally present flavones that shows diverse pharmaceutical properties i.e., anti-oxidant, anti-inflammatory and anti-apoptotic. Therefore, the present study was designed to evaluate the therapeutic role of SNS against PS-NPs induced hepatotoxicity. 48 rats were distributed into 4 groups i.e., control, PS-NPs (50 µgkg−1) treated, PS-NPs + SNS (50 µgkg−1 + 20 mgkg−1) co-treated and only SNS (20 mgkg−1) treated group. PS-NPs intoxication reduced the activities of catalase (CAT), glutathione-S-transferase (GST), superoxide dismutase (SOD), glutathione peroxidases (GPx) glutathione reductase (GSR) and glutathione (GSH) level, whereas increased the levels of ROS and MDA. Additionally, PS-NPs increased the levels of liver serum marker enzymes i.e., alanine transaminase (ALT), alkaline phosphatase (ALP) and aspartate aminotransferase (AST). Moreover, the level of inflammatory makers such as nuclear factor-kappa B (NF-κB), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1 beta (IL-1β) and cyclooxygenase-2 (COX-2) activity were increased following the PS-NPS exposure. The intoxication of PS-NPs elevated Caspase-3, Bax and Caspase-9 levels, while reducing the Bcl-2 level. Furthermore, the exposure of PS-NPs induced significant histopathological damages in hepatic tissue of rats. However, the supplementation of SNS considerably improved the PS-NPs induced damages as well as histological changes due to its hepatoprotective, anti-inflammatory, anti-apoptotic and anti-oxidant nature.

Lactobacillus plantarum Enhanced the Cardioprotective Efficacy of Arctiin in Isoproterenol Cardiac Injury in BALB/c Mice

Background Isoproterenol is a drug used for the treatment of bradycardia that has many side effects due to its non-selective β-adrenoceptor agonist properties. Aim In this study, we evaluated an in vivo experimental model for isoproterenol (ISO) cardiac injury using BALB/c mice and protective treatment with a combined optimized dose of Arctiin (AR) and Lactobacillus plantarum (LP) (ARLP; 30 mg/kg b.w. AR and viable 106 CFU/mL LP p.o.) together. Introduction Isoproterenol causes cardiac injury in many instances. Arctiin is a naturally occurring lignin glycoside present in many herbal medicinal plants that has many beneficial effects for humans. Lactobacillus plantarum is yet another beneficial probiotic that benefits largely to humans. Materials and Methods Male BALB/c mice in appropriate groups (6 animals each) were treated with ARLP for 7 days with ISO administration (100 mg/kg i.p.) on days 5 and 6. On the 8th day, animals were sacrificed. Serum and heart samples were collected for further processing. CK-MB, cardiac troponin, AST, ALT, LDH, GST, GPx, CAT, SOD, GSH, GSSG, MDA, nuclear factor kappa B (NFκB), TNF-α, and IL-6 by ELISA and gene expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) were estimated in samples. Results Mice administered with ISO showed a prominent rise in the serum marker enzyme activities and tissue oxidative stress markers (MDA and GSSG). Furthermore, marked reductions in body weight and enzymatic and non-enzymatic antioxidant levels were noticed in ISO toxicity. Alterations in proinflammatory cytokines (TNF-α and IL-6) and Nrf2 levels by RT-PCR were analyzed. Histopathology of the heart also indicated cardiac injury in ISO-intoxicated mice. ARLP pretreatment prevented all these cardiac injuries and exerted significant ( p ≤ 0.05) prophylactic protection toward cardiac tissue. Further, we analyzed the possible interactions between AR and LP in vitro, to understand the influence of ARonLP, which showed no significant suppressive/antibacterial activity on LP. Conclusion In conclusion, ARLP exerts a strong cardioprotective and anti-inflammatory activity in cardiovascular injury.

An analysis of Heptoprotective effects of plant extract on albino rats by Deep Learning analysis using ResNet and VGG16 algorithms

The hepatoprotective and anti-inflammatory effects of Terminalia catappa L. and Pergularia daemia hydroalcoholic extracts in albino rats with CCl4-induced liver damage (HAETC and HAEPD, respectively). The extracts significantly reduced the harm induced by CCl4 when given orally at a dosage of 200mg/kg. They also showed strong hepatoprotective and antioxidant properties. Wistar albino rats in good health were divided into seven groups, each with six animals. Group I acted as the control and received no treatment, whereas Group II was given 30% CCl4 (1ml/kg, intraperitoneally) to cause hepatotoxicity. After administering Silymarin (25 mg/kg, orally) as per protocol, Group III underwent CCl4 therapy. The CCl4-induced rats showed significant reductions in antioxidant enzymes like SOD, catalase, glutathione peroxidase (GPX), and glutathione-S-transferase (GST), as well as increases in serum marker enzymes like SGOT, SGPT, alkaline phosphatase (ALK), ACP, LDH, and lipid peroxidation (LPO) activity. However, rats given HAEPD and HAETC showed significant improvements, returning these parameters to levels that are almost normal (P 0.001).The hepatoprotective and antioxidant benefits of Terminalia catappa L. (HAETC) and Pergularia daemia (HAEPD) against CCl4-induced hepatotoxicity in rats were further validated by histopathological analysis of liver tissues. It encourages the use of pre-trained CNN architectures, such as VGG16 and ResNet (Residual Network), in the proposed method, which uses convolutional neural networks (CNNs) for histopathological image analysis to assess the hepatoprotective properties of Pergularia daemia and Terminalia catappa L. leaf extracts against CCl4-induced hepatotoxicity. These well-known CNN models may be modified for precise and effective histopathological image interpretation, assisting in the evaluation of the impact of plant extracts on liver health.

Introduction: The aim of the study was to evaluate the hepatoprotective effect of aqueous extract of Garcinia kola) seeds on carbon tetrachloride (CCl4) induced liver damage in adult Wistar rats. Thirty adult Wistar rats weighing between 65-145g were randomly divided into six groups of 5 rats each. Group A (control) rats were orally administered with 5ml/kg body weight of distilled water daily for 2 weeks, group B rats were administered distilled water orally daily for 2 weeks (volume per body weight) and carbon tetrachloride (CCl4) 0.4 m1/kg intraperitonially as a single application on day 14 of the experiment. Group C rats were administered 100 mg of silymarin / kg body weight once daily for 2 weeks followed by a single dose of CCl4 (0.4 m1) on day 14 of the experiment. Group D rats were administered 400 mg aqueous extract bitter kola (Garcinia kola) / kg body weight orally once daily for 2 weeks. Group E and F rats were administered 400 mg and 200 mg aqueous extract bitter kola (Garcinia kola) seed) orally once daily for 2 weeks followed by a single dose of CCl4 (0.4 m1) on day 14 respectively. At the end of the experiment. Garcinia kola seed aqueous extract caused significant decrease in the aspartate aminotransferase (AST) levels in the serum of the extract treated groups. Histopathological examinations revealed distortion of histoarchitecture such as, sinusoidal congestion, necrosis, steatosis and fibrosis was observed in group B. The administration of aqueous extract of Garcinia kola seed remarkably inhibited histoarchitectural distortion induced by CCl4 administration. Effects of the extract at dose of 200mg/kg was comparable to the reference drug. Garcinia kola aqueous seed extract showed a remarkable hepatoprotective and antioxidant activity against CCl4 induced hepatotoxicity as observed from the serum marker enzymes and antioxidant levels in liver tissues. CCl4 induced a significant rise in AST, ALT, and ALP with an increase of superoxide dismutase (SOD), catalase (CAT) and reduction lipid peroxidation (MDA). Treatment of the rats with the extract significantly (p&lt;0.05) altered serum marker enzymes and antioxidant levels to near normal compared with CCl4- treated rats (group B). The activity of the extract at dose of 400mg/kg (group F) was comparable to the standard drug confirmed by histopathological examinations of liver sections. Conclusion: Garcinia kola aqueous extract has hepatoprotective and antioxidant properties against CCl4-induced hepatotoxicity in Wistar rats.

Equivalent evaluation and biological ingredients of Syringa pinnatifolia against acute myocardial ischemia in mice

Ethnopharmacological relevanceThe peeled roots, stems, and twigs of Syringa pinnatifolia Hemsl., known as Shan-Chen-Xiang (SCX) in Chinese, has the traditional effects such as anti-Khii, clearing heat and relieving pain. It has been clinically applied for the treatment of heart failure and mental abnormalities, and gradually replaced agarwood in Mongolian medicine. Aim of studyThe present study aims to evaluate whether the key subfraction C (C), a half composition in mass of total ethanol extract (T) of SCX, exerts an equivalent effect against acute myocardial ischemia (AMI) compared to fraction I (I), and what was the potential pharmacologically active constituents of SCX. Materials and methodsCardiac function, serum marker enzymes, and myocardial tissue pathology of infarcted mice with ligation of the anterior descending (LAD) branch of the left coronary artery were used to evaluate the anti-AMI effect of C and its equivalent potency to that of I. LCMS-IT-TOF was used to identify the main constituents in C and C−. The new and known compounds were isolated from C by a combination of mass spectrometry and bioactivity-guided fractionation methods, and structures were elucidated by extensive spectroscopic and chemical methods, including calculated 13C NMR data, calculated electronic circular dichroism, and single-crystal X-ray crystallography. The protective effect of isolates against oxidative injury induced by H2O2 in H9c2 cells was evaluated according to a previously reported protocol. ResultsThe results of cardiac function, serum marker enzymes and myocardial tissue pathology observations (fosinopril as a positive drug) suggested that C (40 mg/kg, orally administered once a day for 7 days) possessed the anti-AMI effect and was equivalent to that of I, while C− did not show the positive effect. Then, 32 lignans were isolated from C, including the majors (8R,8′R,9S)-4,4′-dihydroxy-3,3′,9-trimethoxy-9,9′-epoxylignan (24) and (8R,8′R,9R)-4,4′-dihydroxy-3,3′,9-trimethoxy-9,9′-epoxylignan (25), which were confirmed by HPLC and LC-MS characterization. Among them, 15 ones were previously undescribed, including a pair of enantiomers (6a/6b), and 11 ones (1, 2, 6a/6b, 8, 10, 12, 16, 17, 24, and 25) exhibited protective effect against oxidative injury to H9c2 cells at different concentrations (ranged from 0.156 to 80 μM). ConclusionC (40 mg/kg) exerts cardioprotective effect in mice, which was equivalent to that of I and T. Lignans, including both representative compounds (24, 25) and other undescribed molecules with low content, significantly contribute to the anti-AMI effect of SCX. However, the anti-AMI property assessment of SCX should not exclude the contribution from the representative sesquiterpenoid ZER. Hence, the exploration of the final potential substances in SCX requires further investigation.

Evaluation of Antidiabetic Effect of Crude Aqueous Extract of Nut, Leaf and Stem Parts of Vigna subterranae on Streptozotocin-Induced Diabetic Rats

Diabetes is a metabolic disorder characterized by abnormally high blood glucose level. One of the plants frequently used to manage diabetes is Vigna subterrenea, also known as the Bambaranut. The aim of this study is to verify the usefulness of this plant to mitigate the effects of diabetes. Thirty (30) Wistar rats weighing 170-200 g were used for this evaluation, the rats were randomly divided into six groups namely; group A: normal control, group B: diabetic control, group C: metformin (500 mg), group D: leaf extract (1000 mg), group E: stem extract (1000 mg), and group F: nut extract (1000 mg). Alkaloids, flavonoids, saponins, balsam carbohydrate, phenol, steroids, and cardiac glycosides were all identified during the phytochemical screening of aqueous extracts. Intraperitoneal injections were used to cause diabetes using streptozotocin across groups and treatment commenced after 48 hours of induction upon confirmation of diabetes mellitus. The sacrifices of animals occurred after a 28-day session of treatment. For hematological and biochemical examination, blood, liver, kidney, and pancreas were obtained. Significantly lowering of fasting blood sugar in the extract treatment groups resulted in improved biochemical markers (P≤0.05). Serum enzyme markers showed a significant drop (P≤0.05) while High Density Lipoprotein (HDL) level increased considerably when compared with diabetic control. Also, when compared to the diabetic control group, the markers of kidney function all noticeably dropped, while electrolyte levels rose. Additionally, there was a significant positive impact on hematological parameters. In accordance with the results of this investigation, V subterrenea is a potent hypoglycemia and hypolipidemic agent on streptozotocin-induced diabetic rats.

Attenuation of Doxorubicin Induced Cardiotoxicity in Wistar Rats by Extracts of Fruits of &lt;i&gt;Ziziphus jujuba&lt;/i&gt; Lam

The objective of the study was to evaluate the cardioprotective activity of fruits of Ziziphus jujuba Lam. in doxorubicin induced cardiotoxicity in Wistar rats. The ethanolic and aqueous extract of fruits of Z. jujuba has been prepared. Male Wistar rats were divided into seven groups. Vehicle control was Group 1. Doxorubicin 5 mg/kg i.p. was administered to Group 2 animals on the 7th and 14th day. Animals in groups 3 and 4 were dosed with ethanolic extracts of 200 and 400 mg/kg p.o. while groups 5 and 6 received aqueous extracts of 200 and 400mg/kg i.p. Animals from group 7 were given nebivolol 5 mg/kg p.o. All the animals were treated for 28 days. Doxorubicin (2.5 mg/kg) was injected intraperitoneally to group 2 to group 7 on day 7th and day 14th. Body weight, ECG, blood pressure, CK-MB, Cardiac troponin-I and LDH were the study parameters. The histology of the heart was performed at the end of the study. Doxorubicin showed cardiotoxicity manifested by changes in serum marker enzymes, ECG and hemodynamic parameters which were further confirmed by histology of the heart. These changes induced by doxorubicin were attenuated by treatment with extracts of the fruit of Ziziphus jujuba Lam. It is concluded that aqueous extract of the fruit of Ziziphus jujuba Lam. (400 mg/kg p.o.) treatment for 28 days protects the heart of rats in doxorubicin induced cardiotoxicity.

Molecular mechanism for the involvement of CYP2E1/NF-κB axis in bedaquiline-induced hepatotoxicity

Bedaquiline (BDQ) is a new class of anti-tubercular (anti-TB) drugs and is currently reserved for multiple drug resistance (MDR-TB). However, after receiving fast-track approval, its clinical studies demonstrate that its treatment is associated with hepatotoxicity and labeled as ‘boxed warning’ by the USFDA. No data is available on BDQ to understand the mechanism for drug-induced liver injury (DILI), a severe concern for therapeutic failure/unbearable tolerated toxicities leading to drug resistance. Therefore, we performed mechanistic studies to decipher the potential of BDQ at three dose levels (80 to 320 mg/kg) upon the repeated dose administration orally using a widely used mice model for TB. Results of BDQ treatment at the highest dose level showed that substantial increase of hepatic marker enzymes (SGPT and SGOT) in serum, oxidative stress marker levels (MDA and GSH) in hepatic tissue, and pro-inflammatory cytokine levels (TNF-α, IL-6, and IL-1β) in serum compared to control animals. Induction of liver injury situation was further evaluated by Western blotting for various protein expressions linked to oxidative stress (SOD, Nrf2, and Keap1), inflammation (NF-ĸB and IKKβ), apoptosis (BAX, Bcl-2, and Caspase-3) and drug metabolism enzymes (CYP3A4 and CYP2E1). The elevated plasma level of BDQ and its metabolite (N-desmethyl BDQ) were observed, corresponding to BDQ doses. Histopathological examination and SEM analysis of the liver tissue corroborate the above-mentioned findings. Overall results suggest that BDQ treatment-associated generation of its cytotoxic metabolite could act on CYP2E1/NF-kB pathway to aggravate the condition of oxidative stress, inflammation, and apoptosis in the liver and precipitating hepatotoxicity.

Influence of anti-hyperlipidemic activity by co-administration of polyamines and rutin with simvastatin

Introduction: Natural polyphenols, rutin, endogenous polycations, and polyamines (spermine and spermidine) are reported to have beneficial effects on hyperlipidemia, obesity, and cardiovascular disease (CVD). The present study attempts to evaluate the combined effects of polyamines or rutin and simvastatin on hyperlipidemic rats. Methods: Wistar rats were maintained on a high-fat diet (HFD) for 60 days. The HFD rats were administered from the 31st day onward with polyamines (PAs), rutin, and simvastatin for the next 30 days. The body weight, serum lipid profile, biomarkers, liver cholesterol, triglycerides, hydroxymethylglutaryl-CoA (HMG-CoA) reductase activity, antioxidants, and marker enzymes in HFD rats were estimated along with the liver histoarchitecture of the rats. Results: The experimental findings demonstrated abnormal alterations in body weight, serum lipid profile, hepatic lipid, and HMG-CoA reductase activity, hepatic antioxidants, serum marker enzymes, blood glucose, total protein, and histoarchitecture of the liver in HFD rats. The aforementioned treatment elicited a significant reduction in the biochemical parameters, biomarkers, and the evaluated enzymes in the present study. Furthermore, an improvement in the histoarchitecture of the liver was observed. Conclusion: The experimental results point out the positive role of antioxidant polyamines along with rutin on different parameters in HFD rats. Thus the combinatorial effect of polyamines and rutin with simvastatin (5 mg/kg) was found to be greater than simvastatin (10 mg/kg) alone. The enhancement in the anti-hyperlipidemic effect of simvastatin may be due to the intrinsic antioxidant property of polyamines and rutin.

Assessment Of Antiarthritic Potential Of Carica Papaya L. Leaves Extract And Fractions: Histopathological Analysis

Carica papaya L has been traditionally claimed for curing inflammation hence the present work exemplifies the anti-arthritic potential of crude leaves extract and its fractions in arthritic models. Screening on this plant has established presence of kaempferol which might possess antiarthritic properties. Kaempferol was quantitatively estimated by high performance thin layer chromatographic method in chloroform fraction and was found to be 0.08% w/w. Arthritis was induced by intraplantar administration considering formaldehyde (2%v/v), turpentine oil emulsion (10%v/v) and complete Freund’s adjuvant (1%v/v) in left hind paw of rats. Paw oedema, body weight, haematological parameters, level of serum enzyme markers, biochemical parameters, interleukin-6 and histopathological analysis were observed in all groups. Present experimental work justifies that in chronic arthritis, iinvolvement of interleukin-6 is associated with non-articular manifestations considering joint inflammation including anaemia. The plant extract and chloroform fraction possess dose dependent antiarthritic effect in acute and complete Freund’s adjuvant induced arthritic model by ameliorating the level of serum enzyme biomarkers, haematological and biochemical parameters, body weight abnormalities, interleukin-6. The experimental explanation established that extract and its fraction of Carica papaya L. revealed anti-arthritic potential.

Evaluation of hypolipidemic activity of homeopathic drug Allium sativum 6C potency on different grades of dyslipidemia in Wistar albino rat models

BackgroundUnhealthy dietary patterns and lifestyle modification could exacerbate heart-related diseases, and the risk factors for cardivascular disease mortality includes dyslipidemia, hypertension, and diabetes mellitus. However, controlling cholesterol, triglycerides, and low-density lipoprotein could minimize the occurrence of risk factors. Although homeopathic preparation of Allium sativum is effective in treating various ailments, it's therapeutic usage by the homeopathic practitioners must be validated scientifically to ascertain its action. ObjectivesThe present study is designed to evaluate the hypolipidemic and anti-inflammatory activities of the homeopathic drug A. sativum 6C in mitigating dyslipidemic changes in different types of dyslipidemic rat models. MethodsAssessment of serum biochemical parameters, evaluation of liver cytokines, and immunoblot analysis of inflammatory proteins were performed in this study. ResultsAdministration of a homeopathic preparation of A. sativum 6C to different types of dyslipidemic rat model showed a significant improvement in the serum lipid profile, reduction in the activity of serum marker enzymes (AST, ALT, LDH, and ALP), and decrement in the levels of liver inflammatory cytokines (TNFα, IL-6, and IL-1β). Further, the expression of inflammatory proteins (CRP, P-Selectin, E- Selectin) down regulated in the liver of dyslipidemic animals upon administration of A. sativum 6C. However, among the various dyslipidemic models, the efficacy of A. sativum is more profound in the HCD and HFD-fed animals. Analyzing the GC–MS data of A. sativum 6C revealed that it contains some active ingredients (Undecane; 1-methylene 1H-Indene, and Oxazolam) that might be responsible for the anti-inflammatory properties of A. sativum 6C. ConclusionHomeopathic preparation of A. sativum 6C modulates the levels of serum biochemical parameters and inflammatory events in HCD-T and T2DM-T animals than in the STZ-T animals, mitigating metabolic dysfunction. Therefore, this study brings limelight to support the potency of the homeopathic drug A. sativum for therapeutic purposes in correcting metabolic dysfunction associated with the current lifestyle.

ASERUM BIOCHEMICAL PROFILES AND IMMUNO-STIMULATORY POTENTIALS OF Clarias gariepinus JUVENILES FED FISH MEAL CONTAINING DIFFERENT INCLUSION LEVELS OF Sesame indicum SEED MEAL

Sesame indicum L. is a class of the Pedaliaceae family of plants that contains good eatable oil, protein, mineral (calcium), and antioxidants and has been recommended as good food for ages. Beni seeds possess a nutritional content that is favour of digestibility, growth, and feed utilization among domesticated animals. The serum biochemical profiles and immunostimulatorypotentials of Clarias gariepinus juveniles fed Sesame indicum seed meal-based diets were carried out. Serum marker enzymes (ALT, AST, ALT, GGT, and LDH), serum chemistry; {glucose (GLU), total protein (TPN), bilirubin (BIL), cholesterol (CHL), albumin (ALB), creatinine (CTN), and immuno-stimulatory potentials; haemoglobin (Hb), packed cell volume (PCV), white blood cells (WBC), lymphocytes (LYM), neutrophils (NEU), monocytes (MON), eosinophil (EOS), and basophils (BAS) in C. gariepinus fed Sesame indicum seed meal-based diets were serum biochemical indices analyzed. High levels of serum marker enzymes {ALT (18.12-22.43U/L), AST (20.13-20.57U/L), ALT (18.62-22.65U/L), GGT (1.72-2.40U/L), LDH (104.35-110.01U/L)}, serum chemistry {Glucose (72.42- 75.34mg/dL), protein (7.01-7.04g/dL), bilirubin (0.44-1.52mg/dL), cholesterol (77.22-82.02mg/dL), albumin (2.46-3.65g/dL),creatinine (0.16-0.23mg/dL), and immuno-stimulatory potential (not greater than the permissible level) were observed in C. gariepinus fed S. indicum seed meal-based diets compared to those fed the control diet (DT1) only. Based on these results, the inclusion of S. indicum in the diets of C. gariepinus could therefore be saved and look promising in terms of health benefits.
