ABSTRACT
The acetone (AEAC) and aqueous extracts (AQEAC) of Adina cordifolia, belonging to the family Rubiaceae, were studied for hepatoprotective activity against Wister rats with liver damage induced by ethanol. It was found that AEAC and AQEAC, at a dose of 500 mg/kg body weight exhibited hepatoprotective effect by lowering the Serum Glutamate Pyruvate Transaminase (SGPT), Serum Glutamate Oxaloacetate Transaminase (SGOT), alkaline phosphate and total bilirubin to a significant extent and also significantly increased the levels of total protein. The hepatoprotec-tive activity was also supported by histopathological studies of liver tissue. Since results of biochemical studies of blood samples of ethanol treated rats showed significant increase in the levels of serum enzyme activities, reflecting the liver injury caused by ethanol and blood samples from the animals treated with AEAC and AQEAC showed significant decrease in the levels of serum markers, indicating the protection of hepatic cells against ethanol induced hepatocellular injury. The effects of AEAC and AQEAC were comparable with standard drug silymarin.
ABSTRACT
The aim of present study was to investigate the attenuating effects of Adenanthera pavonina L., Leguminosae-Mimosaceae seeds aqueous extract (APSAE), in streptozotocin (STZ)-induced diabetic neuropathy in rats. APSAE (50, 100 and 200 mg/kg per day) was given to diabetic rats for twelve weeks. Cold and hot water tail immersion tests, photoactometer and Rota-rod tests were performed to assess degree of colder, thermal, spontaneous motor activity and motor co-ordination changes respectively at different time intervals i.e., week 0, 4, 8 and 12. Tissue superoxide anion and total calcium levels were determined after twelve weeks to assess biochemical alterations. Histopathological evaluations of sciatic nerve were also performed to assess nerve damage. APSAE treatment increased tail flick latency significantly in diabetic rats. APSAE also reduced superoxide anion and total calcium levels. These results suggested that APSAE has attenuated development of diabetic neuropathy in streptozotocin-induced diabetic rats when compared with pregabalin (10 mg/kg, p.o.) and could be beneficial in preventing the progression of diabetic nephropathy.
