Abstract
The diuretic activity of methanol extract of Oxystelma esculentum aerial parts (MEOE) was studied in male Wister albino rats at 5h and 24h interval. The animals were divided into 5 groups: control, urea, furosemide and 200mg/kg and 400mg/kg MEOE. The extract was administered intraperitoneally (i.p) pretreated and all animals were saline MEOE. The urine volume (in mL) and electrolytes excretion (Na + , K + , Ca 2+ and Cl - ) at 5h and 24h duration were measured. The urine output increased significantly in urea, furosemide and both MEOE groups ( p <0.001). MEOE increased the urine volume and electrolytes balance in a dose dependent manner. The results indicate that MEOE is an effective hypernatramic, hyperkalaemic, hypercalcemic and hyperchloremic diuretic, which supports the traditional claim about the Oxystelma esculentum being used as a diuretic.

Abstract
This study was designed to evaluate the hepatoprotective and antioxidant activity of methanol extract of Lippia nodiflora (MELN) in acute experimental liver injury induced by paracetamol (750mg/kg, b.w). MELN at the doses of 200 and 400mg/kg, p.o was administered for 7 days and biochemical parameters such as serum glutamate oxaloacetate transaminase (SGOT), glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), bilirubin and total proteins with enzymatic and non-enzymatic antioxidant level were recorded. MELN at both doses prevented the increase in liver weight when compared to hepatotoxin treated control. The higher dose (400 mg/kg) of Lippia nodiflora extract was found to be more effective than the lower dose (200 mg/kg) in paracetamol induced liver damage. MELN produced significant ( p <0.001) hepatoprotective effect by decreasing the activity of serum enzymes such as SGOT, SGPT, ALP, bilirubin and lipid peroxidation while it significantly (p<0.001) increased the levels of total proteins, glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) in a dose dependent manner. The activity of MELN was compared with standard drug silymarin (25mg/kg), which is a well-known natural anti-hepatotoxic drug and the potency of MELN is more or less the same at that of silymarin. It is concluded that the methanol extract of whole plant possesses good hepatoprotective activity probably by its antioxidative potential on hepatocytes.
