Abstract
The number of patients with hypertension, obesity, diabetes, and hyperlipidemia is increasing. This tendency is observed in pregnant women, in whom many obstetrical and perinatal complications occur. The prevention of these abnormalities is important in reducing perinatal mortality and the risk of coronary disease. We established a pregnant rat model with diabetes and signs and symptoms mimicking preeclampsia. On day 6 of pregnancy, streptozotocin (STZ) or citrate buffer was injected into the tail vein. After STZ administration, plasma glucose was increased within 48 hours and sustained at a high level until day 20 of pregnancy, and plasma insulin was decreased. Fetuses from STZ-treated mothers were growth-restricted, and plasma glucose was 6-fold higher in fetuses of STZ-treated versus control rats. The systolic blood pressure, urinary protein, and hematocrit were increased significantly in STZ-treated rats. Total cholesterol and triglycerides were also elevated in STZ-treated rats, but plasma leptin levels were decreased. The STZ-induced diabetic pregnant rat model exhibited preeclampsia, hemoconcentration, hyperlipidemia, hypoleptinemia, and intrauterine growth restriction. This model closely mimics the features of human pregnancy complicated by diabetes and is useful for the basic study of the pathophysiology of pregnancy with diabetes. Copyright (C) 2000 by W.B.
