Effects of ethanolic extract of Ocimum gratissimum leaves (O. gratissimum)
on the kidneys in Streptozotocin-induced diabetic rats were studied.
Thirty-six adult rats were assigned into six groups (A, B, C, D, E and F) of
six rats each. Diabetes was induced with a single intraperitoneal injection
of Streptozotocin. Group A (non diabetic control) and F (diabetic control)
received normal saline orally, group B received a Metformin at 25 mg/kg
while groups C, D and E had O. gratissimum at 400, 600 and 800 mg/kg.
Body weight and fasting blood glucose levels were monitored weekly; blood
levels of Creatinine (Cr) and Urea (U) were measured on day twenty eight.
Animals were sacrificed and kidney sections processed for histological
study. Statistical analysis was carried out using a one way ANOVA followed
by a post-hoc test. Results showed significant reduction in body weight and
blood glucose levels in the groups that received either metformin or O.
gratissimum as well as dose dependent increase in blood urea and
creatinine levels, histopathology revealed varying degrees of renal injury.
The study concluded that O. gratissimum worsens diabetes induced
renal injury.
