Editan (Lasianthera africana) leaf-inclusive diets modulate some neuronal enzyme activities and antioxidant status of cyclophosphamide-treated Wistar rats.

The effect of Editan (Lasianthera africana) leaf inclusive diet (ELD) on neuronal cholinesterases (ChE), ecto-5'-nucleotidase, and endogenous antioxidant indices [superoxide dismutase (SOD), catalase (CAT), glutathione (GSH)] in cyclophosphamide (CYP)-administered albino rats were investigated. Thirty male albino Wistar rats were dissevered appropriately (n = 6). Group I-normal control rats (NC), II-untreated CYP-administered rats, III-CYP-administered rats pre-treated with donepezil (DON), group IV-CYP-administered rats fed ELD, and V-normal rats fed with ELD for 21 days. Results obtained revealed that CYP-administered rats significantly (p < .05) had elevated activities of ChE, ecto-5'-nucleotidase and thiobarbituric acid reactive species (TBARS), and concomitantly decreased in the antioxidant indices. However, pre-treatment with either DON or ELD reversed these effects, thereby eliciting a therapeutic effect which could be linked to the rich polyphenol and alkaloid constituents in the studied leaf, and could be responsible for the potential ethnopharmacological actions of the ELD in the management neurodegeneration. PRACTICAL APPLICATIONS: Currently, the use of plant-food to control diseased conditions due to their phytochemicals has been explored, most especially, the indigenous edible vegetables from the Southwestern part of Nigeria. "Editan" leafy vegetable scientifically known as Lasianthera africana is commonly used in soups preparation and in folklore for the management of some human ailments. Editan leaf is a rich source of alkaloid and phenolic compounds, which could be used to treat and or manage neurological diseases. This study, therefore, unravels the fact that the studied leafy vegetable possesses therapeutic potentials toward the management of neurological disorders.

Nutritional content of selected species of tropical eggplant fruit (Solanum spp) diet Attenuates hepatic inflammation in high-fat fed male Wistar rats induced with streptozotocin.

Tropical Solanum species contains a high level of phenolic acids and flavonoids, which were found to inhibit some key enzymes associated with the incidence of type 2 diabetes in in vitro and in vivo models based on earlier studies. This study was further designed to compare the nutritional properties, glycemic index, and hypolipidemic and the antioxidant effects of three species of tropical eggplant fruit (Solanum kumba, Solanum aethiopicum, and Solanum gilo) diet on streptozotocin (STZ)-induced nephrotoxicity in male Wistar rats. The animal model was subjected to high-fat diet prior to interperitional administration of streptozotocin (35 mg/kg wt); thereafter, the rats were given supplemented eggplant fruit diet, which lasted for 14 days. Determination of lipid content [triglycerides (TG), low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and total cholesterol (TC)], was assessed, while the liver biomarker enzymes alanine aminotransferase (ALT) alkaline phosphatase (ALP) and aspartate aminotransferase (AST), also endogenous enzymes such as superoxide dismutase (SOD) and catalase (CAT), were determined. Histopathological assessment of inflammation was carried out on kidney while the blood urea nitrogen (BUN), uric acid, and creatinine level on the kidney function were determined. The results showed that the groups with supplemented eggplant diet had significant (p < 0.05) reduction in lipid profile, decreased leakages of the liver, and kidney function enzymes while there was restoration of depleted endogenous antioxidant enzymes. The inflammatory cells and fat deposit from the histopathological view were reduced. However, S. kumba had the best nutritional output.
