气象因素对脑血管病的发病有一定的影响,是急性脑血管病的一个重要危险因素,但其机理目前尚不清楚。为此,我们用模拟气象条件观察了各种气象因素对血管活性物质ET、TXB_2、6-Keto-PGF_（1α）的影响,现报道如下。 材料和方法 一、气象条件的设置:在模拟气象箱内进行高温为35±1℃,低温为4±1℃,高压为1035mb,高湿度为100％,低湿度为30％。根据气象条件设置的不同分为以下七组:对照组、高温组、低温组、高湿度组、低湿度组、高气压组、复合气象组(高压+低湿),所用动物为新西兰大白兔,每组5只动物。每组除设置的气象条件外,其余气
Meteorological factors have a certain impact on the incidence of cerebrovascular disease, is an important risk factor for acute cerebrovascular disease, but the mechanism is not yet clear. To this end, we observed the meteorological conditions of various meteorological factors on the vasoactive substances ET, TXB_2, 6-Keto-PGF_ (1α), are reported below. MATERIALS AND METHODS I. Setting of meteorological conditions: The high temperature in the simulated meteorological box is 35 ± 1 ℃, the low temperature is 4 ± 1 ℃, the high pressure is 1035mb, the high humidity is 100% and the low humidity is 30%. According to different weather conditions, the animals were divided into the following seven groups: control group, high temperature group, low temperature group, high humidity group, low humidity group, high pressure group and compound meteorological group (high pressure + low humidity) Group of 5 animals. In addition to each set of weather conditions, the remaining gas
