Grade II chronic intermittent hypoxic hypoxia under normal barometric pressure, which was reproduced in pregnant rats 2.0-2.5 weeks before expected delivery and in the offsprings in the first 2 days of neonatality caused a decrease in serum albumin functional activity associated with bilirubin transport, as evidenced in vitro, as well as accumulation of serum albumin-bound nonesterified higher fatty acids and acetaldehyde along with uncompensated acidosis, an increase in brain levels of bilirubin in adult and newborn rats, and enhancement of its hemoxygenase activity. Administration of alpha-tocopherol acetate, nicotinamide, sodium oxybutyrate, and trisamine to animals exposed to hypoxia normalized the above biochemical parameters, except for hemoxygenase activity and promoted a greater binding of endogenous bilirubin to albumin in adult and newborn rats in vivo.
常压低氧下的II级慢性间歇性缺氧,在预计分娩前2.0 - 2.5周的孕鼠以及新生期头2天的仔鼠中重现,导致与胆红素转运相关的血清白蛋白功能活性降低(体外实验证明),以及血清白蛋白结合的非酯化高级脂肪酸和乙醛积累,同时伴有未代偿性酸中毒、成年和新生大鼠脑内胆红素水平升高及其血红素加氧酶活性增强。对暴露于缺氧环境的动物给予醋酸α-生育酚、烟酰胺、羟丁酸钠和三甲胺,可使上述生化参数(血红素加氧酶活性除外)恢复正常,并促进成年和新生大鼠体内内源性胆红素与白蛋白的更大结合。
