Background: Diazinon is a globally used pesticide. Morus nigra (Black Mulberry) possesses flavonoids and phenols, which act as antioxidants. The objective of this study was to determine the possible protective effects of Morus nigra leaf extract on Diazinon-induced hepatotoxicity in rats. Material and Method: It was an experimental study conducted in the Department of Anatomy, Postgraduate Medical Institute, Lahore. A total of 36 healthy male Wistar albino rats were divided into three groups with 12 rats in each group. Group I was the control group. Group II was treated with 60 mg/kg body weight (bw) Diazinon daily for 4 weeks through orogastric intubation. Group III was treated with Diazinon 60 mg/kg bw daily along with 350 mg/kg bw of Morus nigra extract daily for 4 weeks through orogastric intubation. Blood samples were collected through cardiac puncture, for estimation of alanine transaminase (ALT) and aspartate transaminase (AST) levels. Liver dissection was done, slides of the hepatic tissue were prepared and studied under light microscope. The histology of hepatocytes, portal lobule, portal vein and sinuosoids was observed. SPSS 20 was used for data analysis. One-way ANOVA followed by Tukey’s test was applied to establish difference among groups with P-value ≤0.05 considered as statistically significant. Results: Histology of Liver tissue in group I showed normal morphology while group II revealed hypertrophy and vacuolization of hepatocytes, congested central vein and sinusoids and presence of necrotic foci. These toxic effects were reversed by the co-administration of Diazinon with Morus nigra in group III which showed normal histology of the hepatic tissue. Similarly, Diazinon administration resulted in significant elevation of ALT and AST levels (P-value<0.05), while, Morus nigra resulted in a considerable decline in the levels of these enzymes (P-value <0.05). Conclusion: Morus nigra extract has hepatoprotective effects against liver toxicity induced by Diazinon.
ABSTRACT Aim and Objective: Acetaminophen, commonly known as Paracetamol is a widely used pain killer. However, its overdose leads to kidney damage. Aloe vera gel has abundant antioxidants. The study was designed to establish the protective effect of Aloe vera gel extract on the nephrotoxicity induced by acetaminophen. Material and Method: Three groups were made each having six rats. The rats belonging to group A (control) were provided standard diet and injected with 5 ml normal saline on the 8th day. Group B rats were fed with normal pellet diet and on the 8th day injected with 1000 mg/kg b.w acetaminophen, dissolved in 5 ml of normal saline. The rats of group C were fed with standard pellet diet along with 400 mg/kg b.w Aloe vera gel extract. On the 8th day, they were injected with acetaminophen, 1000 mg/kg b.w dissolved in 5 ml normal saline. The kidneys of all rats were removed and studied under light microscope. The biochemical markers including blood urea nitrogen (BUN), serum creatinine and uric acid levels were measured. Glomerular morphometry was done to evaluate the renal morphology. Results: Aloe vera gel extract produced a significant improvement in the glomerular diameter (p value< 0.01). Biochemical markers including blood urea nitrogen and creatinine were improved and uric acid levels were significantly reduced (p value<0.01). Conclusion: Aloe vera gel extract can serve as an easily available and a safe prospect for the treating nephrotoxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
