ABSTRACT
Objective To observe the effects of soy isoflavones (SI) on NO content and NOS activity in myocardial tissues of diabetic rats. Methods Forty-eight SD rats were randomly divided into six groups normal control group (NC), diabetic control group (DC), SI groups in low, moderate and high doses respectively (L-SI, M-SI, H-SI) and nilestriol group (NI). Except the NC group, the rats were given streptozotocin (STZ) 55mg?kg-1 intraperitneally (ip). From the 7th week, SI in the dosage of 30, 60, 120 mg?kg-1?d-1 was respectively given to L-SI, M-SI, H-SI groups by gastric gavage, nilestriol 0.2 mg?kg-1?per week was given to NI group,and 0.5%CMC-Na10 ml?kg-1?d-1 was given to NC and DC groups. After treatment, fasting blood sugar level, body weight, serum lactate dehydrogenase (LDH)and creatine kinase (CK) contents, and NOS activities and NO content in myocardial homogenate were measured. Results 1) LDH and CK contents in serum were significantly higher in DC group than those in NC group. Compared with DC group, LDH and CK were significantly decreased in M-SI and H-SI groups (P
