[Studies on the viability of trophoblast after termination of various kinds of pregnancies (author's transl)].
Although normal value of hCG (LH level) does not necessarily indicate eradication of viable trophoblast, its confirmation has been demonstrated as a clinically useful guide for the probable prevention of choriocarcinoma after hydatidiform mole by Takeuchi et al. Choriocarcinoma preceded by other pregnancies than hydatidiform mole which has the highest risk for choriocarcinoma has drawn more attention than before in connection with the decrease of postmolar choriocarcinoma. So that I have studied the regression rate of urinary gonadotropin (hCG) after the termination of various kinds of pregnancies. ⋯ At one month after the termination of pregnancy, 80.1%, 11%, 0.3%, 8% and 4.1%, and at two month 55.8%, 1.6%, 0.5%, 4% and 0.5% for hydatidiform mole, induced abortion of less than 12 week of gestation, spontaneous abortion of less than 12 week of gestation, spontaneous abortion of between 13 and 20 week of gestation respectively still showed abnormal hCG value. One percent of induced abortion at 5 month, 4% of spontaneous abortion at 3 month, 0.3% of term delivery at 4 month still maintained abnormal titer. No malignant sequelae in patients under the investigation have ever been observed in the follow up period between 3 and 8 years.

[Clinical analysis of the pain pathways of labor (author's transl)].
Segmental epidural blocks by double catheters which were inserted in the thoracolumbar (Th12-L1) and lower lumbar region (L4-L5) were performed in eleven primiparas to investigate the correct pain pathways of labor and the sensory innervation of uterus. It is generally believed in Japan that the sensory nerves of the cervix of uterus enter the cord through the sacral segments (s2,3,4) and the uterine body through the thoracic segments (Th11, Th12). 5 ml dose of 0.5% bupivacaine (Marcaine) was used to the upper catheter (Th12-L1) during the first stage of labor. Segmental spread of analgesia was on average Th9.4-L1,6 and the duration was 1 hr 57 min +/- 34 min. ⋯ Th11. Th12. L1 segments and no relation to sacral nerves.
