许多研究者曾视察高温条件下工作的女工卵巢月经机能的变化,因此提出阐明高温对性系统作用机制的重要性。作者以体重140±5g的成熟雌性大白鼠作试验,动物于12个月中(休息日除外)每日接受40℃高温作用2小时。按一般采用的阴道涂片法研究其动情周期。结果证明,在高温的作用下,自实验的第5个月开始,动情周期的平均持续时间增加,统计学上有显著性。至第12个月,其动情周期平均持续时间为7.60±0.80天,而对照组为4.62±0.55天。自第7个月开始与对照组比较,动情期和动情前期的样品数显著减少,而动情间期的样品数显著增加。至第12个月动情期样品数为14.9±2.5%(对照组24.2±1.86%),动情前期为10.1±2.1%(对照组17.04±1.64%),动情间期为72.6±3.1%(对照组
Many researchers have examined the changes in the ovarian menstrual function of female workers working under high temperature conditions and therefore proposed the importance of clarifying the mechanism of action of high temperature on the sexual system. The authors tested in a mature female rat weighing 140 ± 5 g and the animals received daily high temperature of 40 ° C for 2 hours over a 12-month period (except for rest days). According to the general vaginal smear method to study the estrous cycle. The results show that, under the action of high temperature, the mean duration of the estrous cycle increases from the fifth month of the experiment and is statistically significant. By the 12th month, the mean duration of estrous cycle was 7.60 ± 0.80 days compared with 4.62 ± 0.55 days in the control group. Since the 7th month compared with the control group, the number of estrus and pre-estrus samples significantly decreased, while the number of estrus samples significantly increased. The number of estrus samples in the 12th month was 14.9 ± 2.5% (control group, 24.2 ± 1.86%), esophageal motility was 10.1 ± 2.1% (control group, 17.04 ± 1.64%), estrus period was 72.6 ± 3.1% (control group
