The effects of acute carbon monoxide poisoning on the hepatic blood flow were studied in mongrel dogs. In this study dogs were divided into two groups, namely control and experimental, and the hepatic blood flow measured by the determination of the fractional clearance of the intravenously administered colloid 198Au. In the experimental group carbon monoxide poisoning was induced by the rebreathing of about 2% CO gas mixture for 15 minutes, and the hepatic blood flow was measured before and 30 minutes after the completion of the rebreathing of the gas mixture. The hepatic blood flow in the experimental group showed a insignificant relative increase compared to that in the control group. The alteration of the mean value of the hepatic blood flow following carbon monoxide poisoning appeared proportionate to that of the cardiac index, and inversely proportionate to those of the femoral artery mean pressure and the total peripheral resistance. However, the individual value of hepatic blood flow revealed no correlation with any of these hemodynamic measurements.

The aim of this study was to assess the degree of association between individual stress and the amount of smoking among male senior students of a medical college. The questionnaire survey was conducted twice for collecting the data on stress level in terms of BEPSl score, smoking amounts, alcohol intake, and residence type in 1992 and 1993. Among the 223 responders, 39.9% were smokers. In the smokers, the association between stress level and smoking amount was significant after controlling for alcohol intake and residence type (P < 0.l). Especially in the group of living without family, the association was more significant (p=0.06). Therefore, it is recommendable that the stress management program is called upon for the student smokers to reduce smoking amount.

The management of pineal region tumor remains controversial. This paper reports a case of pineocytoma which was attempted to improve treatment planning by the use of clinical features, computerized tomography, and markers for germ-cell tumor. A presumptive diagnosis could be made and this tumor less likely to respond to radiotherapy was subjected to primary surgery.

A 44-year-old female with cervical cord compression signs had myelographic and computerized tomographic evidence of extradural spinal cord compression without any tuberculous bony lesion or cold abscess. At surgery, cervical spinal cord was compressed by extraosseous extradural granulomatous tissue which was histologically proved a very rare localized extradural tuberculous granuloma.

The authors report a case of massive spontaneous intracerebral hematoma in a infant, caused by bleeding from cryptic vascular malformation associated with vitamin K dependant factor deficiency. The bleeding was initiated by vitamin K dependant factor deficiency, then 3 weeks later hematoma was expanded by rebleeding from malformed vessel after PT and PTT had been returned to normal values. The well circumscribed organized old hematoma with fresh expanded bleeding component within a huge rusty colored cystic fluid cavity was recognized in operative field and pathological ground.
