SUMMARY:Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris (T. terrestris) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n=6). Animals in experimental groups were received high fructose diet (70 %) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey's post-hoc multiple comparison test and P<0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P<0.05) and serum lipid profiles (P<0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P<0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.
This study aimed to investigate the effect of pentoxifylline on complications of prolonged usage of morphine upon the testis and sperm parameters of rats. In this study, forty male Wistar rats were divided into five groups (n = 8) and treated for 56 days to only saline, only morphine, only pentoxifylline, pentoxifylline + morphine and naltrexone + morphine. The diameters of seminiferous tubules, the maturity of germ line epithelium and sperm parameters were evaluated. The expression of inflammatory-related factors in testis tissues were also investigated at gene and protein levels. The data were calculated by one-way ANOVA test followed by Tukey's post hoc test using SPSS software for windows (version 20). Seminiferous tubule diameter, the maturity of spermatogonia and sperm parameters were significantly decreased in morphine group in comparison with control, pentoxifylline and pentoxifylline + morphine groups (p < .001). The expression of anti-inflammatory markers, at both gene and protein levels, was significantly increased in testis of morphine-treated rats in comparison with other groups (p < .001). Chronic morphine administration induces destructive effects on male reproductive system by regulating inflammatory responses. Pentoxifylline recovers the destructive effects of morphine on male reproductive system by inhibiting TLR (Toll-like receptor) activity, as an anti-inflammatory response.
Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.
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.
