    Various culture systems are now available to study erythropoiesis in vitro. These include suspension and cloning culture techniques. Suspension culture techniques are frequently used for studying biochemical changes in erythroid cells, while cloning culture techniques are suited for investigating the nature of erythroid stem cells. Some aspects of human erythropoiesis will be clarified by employing new methods such as the Marbrook diffusion chamber technique.

    In the central nervous system, motor and sensory system are a convinient context in which to observe some physiological response. Additionally the rela-tionship between behavior and neurophysiological findings are easy to identify. The purpose of this paper is to clarify the mechanism of recovery of motor function after making small lesions which are small in comparison with those studied earlier. Furthermore an attempt was made to elucidate the relation-ship between motor control and sensory evoked responses. Measurements of behavioral motor function, evoked movements by brain stimulation and sensory evoked responses were taken from monkeys with array of 36 electrodes chroni-cally implanted in sensory motor cortex, before and after small electric lesion. The study was performed in two groups, the group of sensorimotor cortical damage and that of the small damage in the internal capsule. The change of three parameters showed the correlation with each other during recovery in the group 1. In the group 2, on the other hand, three parameters were not always similar in the recovery process. In the recovery of motor function, participation of the function of the area adjacent to the injured site could represent one of the important factors. Observation on sensory evoked re-sponse provided a better indicator of the recovery of motor function in the group 1 than in the group 2.

    Antibiotic susceptibilities of various bacteria on various media under aerobic and anaerobic conditions were examined. From these results, antibiotic susceptibilities and the resistance mechanisms of anaerobic bacteria can be discussed with the same standard as aerobic bacteria and also difference of antibiotic activities of various drugs under aerobic and anaerobic conditions was made clear.

    Using expired CO analysis by 20-second breath holding method, various population groups were investigated to evaluate their body burden of carbon monoxide. For urban children mean expired CO level was 2.2 ppm in autumn and 3.8 ppm in winter, and for rural children 2.8 and 6.6 ppm in the same sea-sons. For urban adult people, 10.1 ppm for male and 8.5 ppm for female, and for male smoker, ranged from 16.9 to 29.3 ppm in ascending order according to daily smoking habit. For rural inhabtants, very high CO level was found in both sexes, 16.4 and 19.0 ppm. This is due to traditional heating facilities in rural area. For urban public bus drivers and street policemen, the higher CO level was estimated, which was attributed to occupational and pollution sources.

    Pregnancy and delivery is one of the main causes in the female body weight alteration, especially with obesity. This alteration in body weight has a significant effect not only for a femine beauty standpoint, but also for more important reproductive functions in postpartum. For the actual condition of the maternal body weight alteration and its clinical significance, we made the various analysis on the mast recent data available at our OB & GYN Dep. of Keio Univ. Hospital, and obtained the following results.
    1. The average maternal weight gains by pregnancy is 11.71kg. Immediately after delivery, the maternal weight gains are on average 5.9kg compared with pre-gestational period 2. Maternal weight gains over 12kg (which are disadvantageous at delivery) have no significance in fetal growth.
    3. 25% of puerpera maintains weight heavier than that of pre-gestational period for four months in postpartum. The group with obesity in postpartum shows the higher rate of anovulatory state compared with the group who recovers the normal body weight in postpartum.
    4. Maternal weight alterations is mostly correlated with the cholesterol level change among serum lipids levels.
