[Ontogeny of behavioral patterns in relation to the concurrent development of central nervous system function, focusing on REM sleep, NREM sleep and waking states in the human fetus].
Behavior is considered a one to one match between the manifestation of a particular individual motor activity (movement) and its correlated brain function. Each motor activity can be seen to run on its own developmental course with advance in gestation, while various movements also develop in concurrence with one another during intrauterine life, gradually integrating into complex and accommodated movements. I emphasized the present study, under real-time ultrasound observation, for investigating whether or not three states: REM (rapid eye movement) sleep, NREM (non-rapid eye movement) sleep and the waking state actually exist in utero, and if so, when the development of these states begins. 1. ⋯ To evaluate whether the waking state is present, 10 fetuses at 36 weeks or more of gestation were examined for a concurrence between miosis/mydriasis and the REM/NREM periods. Using pupil diameter as a parameter, miosis and mydriasis were distinguished from each other, statistically, by means of "least median of squares regression". Accordingly, the NREM period was occupied only by miosis (41.0% of total observation period), while the REM period was divided into two conditions: 52.6% with miosis and 6.4% with mydriasis.(ABSTRACT TRUNCATED AT 400 WORDS)

Comparative Study[Umbilical blood-gas status at cesarean section for breech presentation: a comparison with vertex presentation].
Umbilical blood-gas status at elective cesarean section with oxygen inhalation for breech presentation (25 cases) was compared with that for vertex presentation (25 cases), so as to confirm the security of full-term breech fetuses delivered by cesarean section under spinal anesthesia. Umbilical arterial oxygen levels were significantly lower in the breech group (Mean PO2:18.9 mmHg; SO2:37.3%; Oxygen content:7.6 ml/dl). The number of hypoxemic fetuses was significantly higher in the breech group (the breech: 7; the vertex; 0). ⋯ The incidence of depression at 1 minute after delivery in the breech infants (24%) was significantly higher than that in the vertex infants (0%). It became obvious in the breech that as the interval between the uterine incision and delivery increased, umbilical arterial blood tended to acidosis and the 1 minute Apgar score decreased. Cesarean section for breech presentation requires sufficient and optimal incisions of the abdominal wall and uterus as well as a skillful manual delivery technique, because the fetus or neonate should be protected against asphyxia resulting from umbilical compression and prolonged delivery interval.

[New method for preventing spinal headache (prophylactic blood patch method)].
After spinal anesthesia, early ambulation frequently caused spinal headache. If the patient was discharged on the day of the operation, spinal headache occurred very frequently. With epidural anesthesia, if the dura was erroneously punctured with the needle, headache often occurred. ⋯ Epidural puncture was performed one spinal segment cephalad (A Method) or one spinal segment cauded (B Method) from the site of spinal puncture. The prophylactic Blood Patch Method was very effective in preventing spinal headache after the dural puncture. Especially B Method, in which blood was injected near the dural pore, was much more effective than A Method.

[Antiemetic efficacy of high-dose metoclopramide, diphenhydramine, methylprednisolone and diazepam on chemotherapy-induced emesis in gynecological malignancy].
The antiemetic efficacy of high-dose metoclopramide (MCP), diphenhydramine (DPH), methylprednisolone (MPL), and diazepam (DZP) was investigated in 40 gynecologic cancer patients for a total of 98 chemotherapy courses, treated with cisplatin (50 mg/m2). With MPL (500 mg i.v. x 2) plus DZP (5 mg i.m. x 2), no vomiting occurred in 0% and mild emesis (vomiting 1-2 times) occurred in 20% of 25 courses. ⋯ These results indicate that high-dose MCP plus DPH are effective in preventing cisplatin-induced vomiting. Furthermore, the antiemetic efficacy of MCP plus DPH (0-2 vomiting episodes: 45%) was significantly enhanced (p less than 0.05) by the combined use of MPL plus DZP (0-2 vomiting episodes: 76%).

[The prevention of CDDP-induced emesis with a combination regimen including metoclopramide, dexamethasone, droperidol and diphenhydramine].
The dose limiting factors of cisplatinum are nephrotoxicity and emesis. Nephrotoxicity has been reduced by hydration but nausea and vomiting caused by cisplatinum have led to refusal of potentially curative therapy by a number of patients. The prevention of nausea and vomiting by a combination of antiemetic drugs administered to ovarian patients receiving chemotherapy inducing (cisplatinum 50mg/m2, adriamycin 300 mg/m2, cyclophosphamide 300 mg/m2 and 5FU 350 mg/m2) was studied. the combination antiemetic drugs were metoclopramide (1mg/kg), dexamethasone (10mg/m2), droperidol (1mg/m2) and diphenhydramine (20mg/body). ⋯ Diphenhydramine was administered intramuscularly 30 minutes before and 5 hours after chemotherapy. No vomiting was noted in 82.6% (19/23) of cases, and no patient vomited more than four times. This combination regimen provided very good protection against cisplatinum induced emesis.
