ABSTRACT
The aim of present study is to evaluate the antidiabetic and hepatoprotective effect of Guaiacum officinale in streptozotocin induced male albino rats. The methanolic bark extract of Guaiacum officinale was administered at a dose of 500 mg/kg and Glibenclamide was used as a standard drug at a dose of 0.5mg/kg for 28 days. The animals were divided in to four groups. Control group n=12, received distilled water. Positive control group (STZ group) n=12 received streptozotocin at 30 mg/kg dose through I/P route. Standard group (STZ+ GLB group): n=12 received Glibenclamide. Treated group (STZ+ extracted group): n=12 received bark extract of Guaiacum officinale. Blood glucose level was significantly reduced after oral adminstration of bark extract in streptozotocin induced diabetic rats. The SGOT level significantly reduced in Guaiacum officinale treated group as compare to control, pronounced reduction of ALT level as compared to GLB and the ALP levels was highly significantly reduced in Guaiacum officinale treated group while GLB is unable to improve ALP levels in GLB treated diabetic albino rats. The level of direct bilirubin in Guaiacum officinale treated group was found to be insignificant as compared to control and STZ treated group while the level of indirect bilirubin was significantly reduced in STZ treated group as compare to control. Histopathological studies showed that Guaiacum officianle have hepatoprotective effect in experimental induced male albino rats.
