Interest in medicinal plant research and usage has risen due to many reported side effects of synthetic drugs and their relatively higher cost. Ocimum americanum (family Lamiaceae) is a commonly used spice in Ghana with the aqueous extracts of leaves, flowers and stem been rich in saponins, alkaloids, flavonoids, and tannins. The aim of the study was to evaluate the nephroprotective potential of the aqueous extracts of O. americanum parts on gentamicin- and cisplatin-induced toxicity in rats. In a ten-day experiment, nephrotoxicity was induced with gentamicin (GM; 100 mg/kg b.wt. for 8 days) and cisplatin (Cisp; 6 mg/kg b.wt. for 1 day) after pre-treatment with 250 mg/kg b.wt. of the leaves, stem, and flower extracts of O. americanum and standard drug, silymarin (100 mg/kg b.wt.) for 10 days. The nephroprotective activity was evaluated by assaying the activity of serum kidney function parameter, kidney oxidative stress parameters, kidney inflammatory cytokines (NF-κB and IL-1) and histopathology. The activities of kidney function parameters of animals were significantly increased following Cisp and GM treatment with resultant alteration is kidney microarchitecture, over-expressions of NF-κB and IL1 and kidney oxidative stress markers. Extract pre-treatment restored kidney function to near-normal, downregulating the expressions of IL-1 and NF-κB and improved levels of reduced GSH contents, GPx and SOD activities. However, leaves extract showed the best protection against GM while all extracts showed improved protection (> 50%) against Cisp. Extract of Ocimum americanum exhibit nephroprotective activity and could be developed as a potent kidney protector.

Liver diseases have continued to be a major health problem in the world’s population with drug-induced liver damage as one of the causes. Tecoma stans (L.) Juss. ex Kunth is an ornamental plant and almost all parts of this plant are of medicinal importance. It exhibits strong antioxidant, anti-inflammatory, antispasmodic, and wound healing activities. This study was conducted to assess the hepatoprotective effects of hydroethanolic extract of Tecoma stans (TSE) against acetaminophenand CCl4- induced liver damage in rats. CCl4 (1 ml/kg body weight dissolved in olive oil) and acetaminophen (500 mg/kg b.wt) was used to induce hepatotoxicity in the animals. Animals were treated with TSE (dose: 100 mg/kg and 250 mg/kg b.wt) and standard drug, silymarin (100 mg/kg), for 7 days. Biochemical parameters such as ALT, AST, ALP, bilirubin (total and indirect), serum proteins (total protein, album and globulin), total cholesterol and triglycerides, creatinine and urea were evaluated. Also, liver histology and oxidative stress assessment were conducted. Significant increases in the major indicators of liver toxicity were observed in the paracetamol and CCl4 only group when compared to the normal. Levels of these biochemical parameters were reduced after the administration TSE (250 mg/kg) and the silymarin (100 mg/kg). The biochemical assessment was supported by histological observations. TSE has shown to possess significant hepatoprotective and antioxidant properties in the current study.
