RESUMEN
Objective: Doxorubicin (DOX) is a frontline antineoplastic drug that kills cancer cells through genotoxic mechanism; however, it induces organ toxicities. This study assayed whether morin hydrate (MOH) could abrogate DOX hepatorenal toxicity in rats. Materials and Methods: There were 4 groups of rats: Control, MOH, DOX and MOH + DOX. Rats were administered MOH (orally, 100 mg/kg bw) for 7 consecutive days, while DOX was injected (40 mg/kg, ip) on the 5th day only. Hepatorenal function markers, and glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT) activities were estimated in both organs. Hepatorenal glutathione (GSH), malondialdehyde (MDA), and nitric oxide (NO) levels were estimated with histopathology. Results: DOX significantly (p<0.05) reduced antioxidant enzyme activities and GSH level, while NO and MDA levels increased (p<0.05) compared to the control. DOX prominently altered hepatorenal indices and induced histopathological alterations. MOH abrogated the DOX hepatorenal toxicity and alleviated the histological lesions in the liver and kidney. Conclusion: MOH restored the indices via antioxidant mechanism and downregulation of NO overproduction in rats.
RESUMEN
This study demonstrated the therapeutic potentials of Cucumeropsis mannii seed oil (CMSO) capable of alleviating BPA-induced dyslipidemia and adipokine dysfunction. In this study, we evaluated the effects of CMSO on adipokine dysfunctions and dyslipidemia in bisphenol-A (BPA)-induced male Wistar rats. Six-week-old 36 albino rats of 100-200 g weight were assigned randomly to six groups, which received varied doses of BPA and/or CMSO. The administration of BPA and CMSO was done at the same time for 42 days by oral intubation. The adipokine levels and lipid profile were measured in adipose tissue and plasma using standard methods. BPA induced significant (p < .05) increases in triglycerides, cholesterol, leptin, LDL-C, and atherogenic and coronary risk indices in adipose tissue and plasma, as well as a decrease in adiponectin and HDL-C levels in Group II animals. BPA administration significantly (p < .05) elevated Leptin levels and reduced adiponectin levels. BPA plus CMSO reduced triglycerides, cholesterol, leptin, LDL-C, and atherogenic and coronary risk indices while increasing adiponectin levels and HDL-C in adipose tissue and plasma (p < .05). The results showed that BPA exposure increased adipose tissue as well as serum levels of the atherogenic index, triglycerides, cholesterol, coronary risk index, LDL-C, leptin, and body weight with decreased adiponectin levels and HDL-C. Treatment with CMSO reduced the toxicities caused by BPA in rats by modulating the body weight, adiponectin/leptin levels, and lipid profiles in serum and adipose tissue. This study has shown that CMSO ameliorates BPA-induced dyslipidemia and adipokine dysfunctions. We suggest for further clinical trial to establish the clinical applications.
RESUMEN
ABSTRACT Objectives: This work investigated the effect of acetogenin-rich fraction of Annona muricata leaves (AFAL) on antioxidant status and some markers of benign prostatic hyperplasia (BPH) in rats. Methods: BPH was experimentally induced in the rats by subcutaneous injection of testosterone propionate (TP, 3â mg/kg) for 28 consecutive days. The rats were administered orally different doses of AFAL (100 and 200â mg/kg) for 7 days. Prostate-specific antigen (PSA), prostate weight, relative prostate weight, prostate protein content and oxidative stress indices of the rats were evaluated. Results: It was observed that 200â mg/kg AFAL significantly reduced the PSA level, mean prostate weights and mean relative prostate weights of the test rats compared to the TP group, and the values were not significantly different from the normal control and group treated with a standard drug. The plant extract also significantly enhanced the antioxidant capacity of the test rats which were evidently compromised in the group that received the exogenous hormone alone. Histopathology of the prostate showed a marked recovery for the test rats after treatment with AFAL. Conclusion: Oral administration of acetogenin-rich fraction of Annona muricata leaves ameliorated TP-induced BPH in rats and significantly enhanced the antioxidant capacity of the rats.
