Physiological studies on the effect of a bradykinin potentiating factor (BPF) isolated from scorpion venom on the burnt skin of alloxan-induced diabetic Guinea pigs.

It is well known that, Wound healing in the diabetes is enormous, growing problem and having cost Medicaid. Therefore, this study produces an exciting prospect, to improve diabetic burn healing, and evaluates the ability of a bradykinin potentiating factor (BPF) isolated from scorpion venom (Buthus occitanus) in treatment of burns in diabetic male Guinea pigs. Male Guinea pigs of approximate (550 g body weight each) were divided into five groups. In the normal group; Guinea pigs were interaperitoneally (i.p) injected with 100 µL saline solution. The second, served as control group which were injected with 100 µL saline solution then standard burns were obtained on the dorsal skin. The 3^rd, 4^th and 5^th groups were i.p. injected with (750 mg /kg, body weight) with a single dose of Alloxan, then standard burns were obtained, after that the 4^th group was treated by BPF in 100 µL saline solutions (1μg/gm. b. w.) topically and the 5^th group treated with BPF (1μg/gm. b. w.) topically and interperitonialy (1μg/gm. b. w. twice a week). Every group contains 20 animals and sacrificed at 15 and 30 days post-treatment by BPF (10 animals per each). The results are recorded after monitoring the CBC including (RBCs, WBCs, platelets, Hb content and HCT percentage), lipid profile including (total cholesterol (TC), triglyceride (TGs), high density lipoprotein (HDL), low density lipoprotein (LDL) and very low density lipoprotein (VLDL)) and the skin antioxidant status (catalase activity (CAT) and superoxide dismutase (SOD) and serum nitric oxide (NO) beside malondialdehyde (MDA) concentration were also monitored during the study compared to normal animals. Also serum glucose level was monitored. The recorded results declared that, the treatment with BPF has shown an ameliorative effect on burn healing in diabetic animals. These observations and investigations were the pacemaker for the hypothesized ameliorating activity of BPF in the present study.
