Paracetamol (acetaminophen) is a widely used non-opioid analgesic and antipyretic drug that is safe at therapeutic doses but toxic to the liver and kidneys in overdose. Although the risk of paracetamol-induced liver injury is much higher than in the kidneys, incidents of kidney damage by paracetamol should not be ignored, given the enormous cost of treating kidney diseases, particularly in resource-challenged developing nations. In an onerous quest for a cheaper and readily available antidote, this study examined the effect of Solanum anomalum fruit extract on paracetamol-induced kidney injuries and haemato-biochemical indices in rats. Twenty-five mature albino rats of both sexes were used, divided into five groups of five rats per group. Group 1 (normal control) rats were given distilled water (10ml/kg) for 8 days, group 2 (negative control) given distilled water (10 ml/kg) for 8 days, group 3 (positive control) given 100 mg/kg Silymarin for 8 days, group 4 given 452 mg/kg of S. anomalum fruit extract for 8 days, and group 5 given 678 mg/kg of S. anomalum fruit extract for 8 days. Thereafter, 2.0 g/kg of paracetamol was administered to groups 2-5 orally on the 8th day. Rats in group 2 showed significant increases in urea, creatinine, sodium ion, total WBCs, decrease in PCV, Hb concentration and RBCs. Administration of Solanum anomalum fruit extract significantly reversed most of these biomarkers. Histopathology of the kidneys also points to the mitigating effect of Solanum anomalum fruit against paracetamol-induced nephrotoxicity.
Peptic ulcer disease is a gastrointestinal disorder of high mortality and morbidity. Therapy of this disease condition with conventional drugs presents therapeutic challenge due to incidents of unwanted side effects, and the high cost of these medications. The use of products from natural sources will provide useful alternatives due to their minimal side effects, being inexpensive, and readily available, especially in resource-challenged nations of the continent of Africa and other developing economies. Oils derived from plants are increasingly being used in management of several disease conditions. This study aims at evaluating the antiulcer activity of extra virgin avocado oil in rodents using ethanol-induced, and indomethacin-induced ulcer models. Test group was given extra virgin avocado oil (1ml per 250g weight) for 7 days before induction of ulcer. Positive controls received omeprazole 30 mg/kg, while negative control animals were given distilled water (10ml/kg) for 7 days respectively, before induction of ulcer. The stomachs were excised and their histopathological examinations carried out. Avocado oil significantly reduced the ulcer index in both models when compared to the negative control group, and histopathological findings corroborate that the oil ameliorates ulcerations in both models. The present study has demonstrated that extra virgin avocado oil possesses significant antiulcer activity.
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.
