许多妇女在行经前有肿胀的感觉,但常无体重增加。这种机理可能是不同部份之间液体的重新分配。心钠素(atrial natriuretic peptide)是1981年发现的。是在心房壁过度伸展时由其肌细胞分泌。在肾脏通过直接的促尿钠和利尿作用引起体液的负平衡。作者对月经周期中心钠素水平是否改变进行了研究。受试者为月经周期规律的14例健康妇女,未服口服避孕药或其它药物。血压≤130/90mmHg。证实有排卵者10例。无排卵的4例不参加试验。平均年龄33.9岁(24～47)。在月经周期第1～6天
Many women have a feeling of swelling before passing through, but often do not gain weight. This mechanism may be the liquid redistribution between different parts. Atrial natriuretic peptide was discovered in 1981. Is over-stretched in the atrial wall by its muscle cells. Negative balance of body fluids in the kidneys through direct natriuresis and diuretic effects. The author of the menstrual cycle atrial natriuretic peptide levels were studied. Subjects for the menstrual cycle of 14 healthy women, did not take oral contraceptives or other drugs. Blood pressure ≤130 / 90mmHg. Confirmed ovulation in 10 cases. 4 cases without anovulation did not participate in the experiment. The average age was 33.9 years (24 ~ 47). In the menstrual cycle of 1 to 6 days
