Effects of Diabetogenic Agent Streptozotocin on Hematological Parameters of Wistar Albino Rats “An Experimental Study”

ABSTRACT

Background:Diabetes mellitus has remained the major concern for medical sciences researches duetoits deleterious effects on general, physical and mental health of patients. To understand the pathophysiology and to explore better treatment options for such kind of metabolic disorders it is necessary to generate the experimental animal models. To create diabetic animal models, streptozotocin has shown predominance in selectivity as a diabetogenic agent. While studying effects of any intervention in the diabetic animal models, being a cytotoxic drug streptozotocin may affect the study results by inhibiting highly replicating cells especially hematopoietic cells.Original ResearchArticle Aims:The aim of study was to analyze the effects of streptozotocin on various cellular components of blood such as RBCs, WBCs (Lymphocytes, Neutrophils, Eosinophils), Hb%, HCT and Platelets, at baseline,5thday and 15thday without any intervention.Study Design:Animal based Experimentalstudy.Place and duration of StudyThe study was conducted at animal house of faculty of Pharmacy Ziauddin University Karachi, while laboratory work was performed at MDRL-1 Ziauddin University.Methodology:In Group A normal saline and in group B and C 60mg / kg streptozotocin diluted in normal saline was administered intraperitoneally. After the confirmation of induction of Diabetes in rats, on fifth day blood samples were drawn from Group A and B and were analyzed. While blood samples from group C weredrawn on fifteenth day.Results:Analysis of various hematological parameters on 5thday revealed that there was a decrease in the levels of Hb, HCT, RBCs and WBCs with an increase in platelet count in group B in comparison to group A (control). On the other hand, in Group C (15th day), blood cell counts (Hb, HCT, RBCs, WBCs, Lymphocytes, Neutrophils and platelets) seemed to recover from streptozotocin induced decline that was observed in group B, however did not reach the baselines as in group A(control).Conclusion:It is concluded that change in hematological parameters of rats after administration of streptozotocin is reversible. The blood parameters may recover near to base line values without any intervention within two weeks
