Role of ethanolic extract of Morus alba leaves on some biochemical and hematological alterations in irradiated male rats

Abstract

Purpose: The present study aimed to evaluate the protective role of “Morus alba Linn (Family: Moraceae) commonly known as mulberry” leaves extract against hazardous effects of gamma rays in male rats.

Materials and methods: Thirty six male albino rats were divided into six groups (six rats/group); (1) control group received 1 ml distilled water, (2) low dose of extract (100 mg/kg) group treated daily with low oral dose of ethanolic extract of mulberry leaves (100 mg/kg body weight (b.wt.)) for 21 consecutive days, (3) high dose of extract (200 mg/kg) group treated daily with high oral dose of ethanolic extract of mulberry leaves (200 mg/kg b.wt.) for the same period, (4) irradiated group rats were subjected to whole body gamma irradiation at a shot dose of 7 Gy, (5) low dose of extract + irradiated group treated daily with low oral dose of ethanolic extract of mulberry leaves (100 mg/kg b.wt.) for 21 consecutive days then rats were exposed to gamma irradiation at a single dose of 7 Gy, (6) high dose of extract + irradiation group treated daily with high oral dose of ethanolic extract of mulberry leaves (200 mg/kg b.wt.) for 21 consecutive days then rats were exposed to gamma irradiation at a single dose of 7 Gy. Rats were sacrificed 1, 7, 15 days post gamma irradiation in all groups. Blood samples were taken at three intervals time in the six groups.

Results: The results showed that whole body irradiation of rats induced significant decrease (p < 0.05) in red blood cells (RBCs), hemoglobin (Hb), hematocrit percentage (HCT%), platelet, white blood cells (WBCs), lymphocytes, neutrophils, serum glucose-6-phosphate dehydrogenase (G-6-PD) and insulin. The data also showed significant increase (p < 0.05) in serum total lipids, phospholipids, cholesterol, triglycerides, lactate dehydrogenase (LDH), creatine kinase (CK), and plasma glucose. Administration of mulberry leaves extract, either low or high concentrations to rats prior to irradiation caused significant improvement in the studied parameters.

Conclusions: Mulberry leaves extract prior to exposure to gamma irradiation has radio protector against hazardous effect of irradiation in male rats.
