Effect of Milk Protein Hydrolysate on Some Hematological Parameters of Type II Diabetic Rats

Milk protein-derived bioactive peptides could be used in human nutrition in both newborns and adults, since they are claimed to be health-improving components that can be used to reduce the risk of disease or to enhance certain physiological functions. This study investigated the effect of oral intake of milk protein concentrate (MPC) and milk protein concentrate hydrolysate (MPCH) on body weight, organ relative weight, and hematological parameters in alloxan-induced diabetes rats. The animals were divided into six major groups after stabilization of diabetes for one week. Diabetic and non-diabetic rats groups were received intra-gastric dose of MPC or MPCH (150mg/kg B.W) for six weeks. Feed treatment by MPC and MPCH significantly (P<0.05) increased the final body weight of normal rats and improved the body weight of diabetic rats and significantly protective (P<0.05) the liver, kidney, heart and lung of normal rats and reduced the fallers of these organs in diabetic rats. The diabetes groups treated by MPCH showed improvement in RBC, Hb, Ht and PLT values. Meanwhile WBC not affected. The oral intake of MPCH protected the normal range of Lymphocytes and S. Nutrophils in healthy and diabetic rats. The oral intake of MPCH caused significant (P<0.05) decrease of Monocytes in diabetic and non-diabetic rats, while the oral intake of MPC had no affected on Monocytes of diabetic and non-diabetic rats. MPC and MPCH reduced the harmful effect of T2D on body weight, organs weights of rats, and improvement most hematological parameters of normal and diabetes rats
