An improved semiquantitative immunoassay method allows human luteinizing hormone (hLH) in urine to be detected from 2.5 to 640 mIU/ml has developed. With this method, the hLH surges in every 3 h urine samples while awake were measured in 8 normal and 12 infertile women. The result was that the urinary hLH surge in infertility was insufficient regardless of the high urinary E2 value. This result may play, at least in part, an etiologic role in infertility.

Primary pulmonary hypertension (PPH) is an uncommon but serious disease. Most patients with PPH are young women and the disease is more serious and eventful in pregnant women. We have experienced a patient with PPH in pregnancy, who was delivered successfully but died suddenly on the 7th day after the delivery. We report the obstetric course and the clinical management for the delivery of the patient with PPH.

The incidence of the hepatic damage during treatment with danazol (D), indicated by increased serum GOT, GPT and LDH levels, has been shown to be high especially in Japan. Thus, the preventive effect of the traditional herbal medicine, shosaiko-to (SS) was investigated in the administration of D and SS for 16 weeks (D + SS group, N = 9) and the pre-administration of SS for about 4 weeks followed by D and SS for 16 weeks (SS----D + SS group, N = 15). The incidence of serum GOT, GPT and LDH levels of more than normal range during the administration of danazol in the D + SS group was similar to that in the previous study of the administration of D alone. But it was significantly lower in the SS----D + SS group than the D + SS group. The mean levels of serum GOT and GPT were much lower in the SS----D + SS group than the D + SS group throughout the administration of danazol and the difference was significant at 8, 10 and 12 weeks in serum GOT levels and at 4 weeks in serum GPT levels. These results indicate that the pre-administration of SS has great efficacy in the prevention of danazol-induced hepatic damage.
