Abstract:
Objective To explore the expression of cardiotrophin-1(CT-1) in myocardium and peripheral blood plasma of neonatal rat with asphyxia and the regulative effect of neuregulin-1(NRG-1).Methods Ninety seven-day-old neonatal rats were randomly divided into 3 groups:asphyxia group (n=40),normal control group (n=10)and NRG-1 pretreatment group (n=40).The model of neonatal rat with asphyxia was prepared by the way of ligation of carotid combined with low supply of oxygen.NRG-1(1 mg/kg) was given to NRG-1 pretreatment group by intraperitoneal injection 30 min before asphyxia.The separated plasma of peripheral blood and myocardium antetheca of aortic ventricle of heart were taken at the time point of 6,12,24 and 48 h.The expression of CT-1 in peripheral blood plasma was detected by enzyme linked immunoadsorbent assay,and that of myocardium was determined by Western blot.Results The expressions of CT-1 protein in peripheral blood plasma of asphyxia group were significantly higher than those of normal control group at each time point,and reached the peak at 24 h(Pa
