Abstract:
The changes in some haematological parameters in alloxan-induced diabetic rats treated with Terminalia catappa leaves extract and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) was studied. 54 male albino wister rats were selected into nine (9) groups of six (6) rats each. Diabetes was induced intraperitoneally to the test groups with 150mg/kg BW of alloxan monohydrate and the experiment lasted for 14 days.
Group 1 was control which received 1mg/kg of deionized water, group 2 was extract treated control group and was given 130mg/kg per body weight (BW) of Terminalia catappa leaves extract, group 3 was diabetic control group and received 1mg/kg BW of deionized water, group 4 being diabetic treated with extract was given 130mg/kg BW of T. catappa leaves extract, group 5 was diabetic treated with aspirin received 30mg/kg BW of aspirin, group 6 was diabetic treated with meloxicam received 2mg/kg BW of meloxicam, group 7 which was diabetic treated with combination of the extract and aspirin received 130mg/kg BW extract and 30mg/kg BW of aspirin, group 8 which were diabetic treated with extract and meloxicam were administered with 130mg/kg BW of extract and 2mg/kg BW of meloxicam, group 9 being diabetic treated with insulin was given 0.75µ/kg BW of exogenous insulin. Blood samples were obtained by cardiac puncture and analyzed using Automated Analyzer (Model BC-5300).
The results showed that diabetes-induced increase in WBC count was reduced by the extract and aspirin but no significant change was seen in the meloxicam treated groups. There was reduction also, in neutrophil, eosinophil and basophil in extract, NSAID and insulin treated groups when compared with diabetic control. Again, the platelet count was increased in extract and aspirin without any significant change in meloxicam treated groups compared to diabetic and control groups. This shows that the extract could ameliorate inflammation in diabetes and its effect is similar to that of aspirin.
