摘要：Objective: The present study investigates the effect of intraperitoneally (IP)-administrated obestatin and short-term treadmill exercise on serum malondialdehyde (MDA) and lipid profile in rat model. Materials and Methods: Forty-five rats weighing 100 ± 5g were selected and divided into five experimental groups; Group-1/control was normally kept and did not receive obestatin-included solution or exercise. Group-2 (placebo) was treated with basal solution (50 ml distilled water). Group-3 was referred to as obestatin-group which was subjected to injection during the experiment with obestatin solution (10 μg obestatin/ rat). Group-4 was known as treadmill-group which was subjected to exercise protocol (15 days treadmill training), and group-5, known as obestatin and treadmill group (OT), was subjected to injection with obestatin and exercise protocol. The exercise-groups were trained for 3-weeks. Results: the treadmill-group was decreased total cholesterol (TC) concentration (67.67 mg/dl), in comparison with control and obestatin-group (79.00 and 78.33 mg/dl, respectively). Similarly with TC level, the triglyceride and HDL cholesterol (HDL-C) was decreased in treadmill-group (‌triglyceride: 70.66 mg/dl in compared with 87.67 mg/dl in control, and HDL-C: 46.10 mg/dl in compared with 57.33 mg/dl in control; P<0.05). Also, level of MDA was decreased in treadmill- and treadmill-obestatin groups. Conclusion: short-term treadmill exercise significantly reduced plasma lipid profile and MDA levels in rat model. Nevertheless, administration of obestatin had no significant effect on lipid profile and MDA. Furthermore, obestatin-administration in combination with treadmill-exercise did not have synergic effect on plasma lipids, MDA level and total protein in rats.
