The 5 cases of human fetal liver aged from 11 to 23 weeks of gestation were investigated for the ultrastructure of sinusoidal wall by electron microscopy. The endothelial cells deficient in basement membrane formed almost all the part of sinusoidal wall. The cells were continued with neighboring cells by intercellular junction, and overlapped them and exhibited to maintain unfenestrated capillary wall, which was different from those with fenestra in adults. The cells were found to have coated pits on luminal side and several various vesicles in the cytoplasms. The cells were related with transcellular migration of reticulocytes and acidophilic erythroblastes, which penetrated into the endothelial cytoplasm to form transient migrating pore closing after the migration into sinusoidal lumen. The perivascular cells were present at perivascular space and surrounding the sinusoid discontinuously. The Kupffer cells were easily identified with filipodia and lamellipodia and with phagosome of nuclei enucleated from acidophilic erythroblasts.

Effects of various factors related to the process of social action of hospital services on the selecting a hospital were investigated by using of questionnaires answered by 1,319 patients in a certain University Hospital, in Chungchongnam-Do, from November, 1986 to November, 1987. The results summarized were as follows ; 1. Each of the examined factors, that is, sincerity of an attendant physician in medical treatment and explaining the condition of a disease, confidence to doctor and nurse, doctor's and nurse's response to calling by patient, kindness of the hospital staffs and food handlers, sanitariness of hospital, cleanness of clothes and bed sheets, hospital foods, and rest surroundings, are not solely decisive to attitude of hospital utilization, but the factors effects compositely on hospital utilization. 2. Hospital services of the social action process are more effective to hospital utilization in cases of the hospitalization caused by the traffic facility than for the medical skill and facilities.

The influences of adrenal corticosteroid on the development and regression of neurons of dentate and hippocampus were studied by adrenalectomy and steroid overload in neonatal rats. The results obtained were as follows. 1. The cell death occurred naturally in numerous dentate granule cells and hippocampal pyramidal cells. 2. The number of dentate granule cells undergoing cell death decreased by injection of adrenal corticosteroid, but increased in adrenalectomized rat brains. The changes occurred prominently at postnatal day 6. 3. The number of hippocampal pyramidal cells undergoing cell death decreased in CA3 region by injection of adrenal corticosteroid, but was not changed in adrenalectomized rat brains. However, other regions exhibited no change by adrenal corticosteroid and adrenalectomy. 4. The cell death of pyramidal cells of CA3 region occurred in close relationship with the cell death of dentate granule cells, which was different from other CA regions. In summary, the cell death of dentate and hippocampal neurons occurred naturally but seemed to be influenced by other factors as well as adrenal corticosteroid.

BACKGROUND: bcl-2 is a newly characterized proto-oncogen that has been shown to suppress programmed cell death(apoptosis), which is involved in tumorigenesis, and its expression has been demonstrated within tumor cells in a variety of neoplasms. OBJECTIVE: We examined whether there are differences in bcl-2 expression in basal cell carcinoma and several epidermal keratinocytic tumors. In addition, we evaluated bcl-2 expression according to histological types of basal cell carcinoma as well as the interaction of expression of bcl-2 and MIB-1 protein in BCC subtypes. METHODS: Routine paraffin sections of formalin-fixed sixty tissues(20 BCC, 10 Bowen disease, 10 keratoacanthoma, and 20 SCC) were labelled with anti-bcl-2 monoclonal antibody and MIB-1 using a labelled streptavidin-biotin complex. RESULTS: 1. Twenty cases of basal cell carcinoma were examined and all expressed cytoplasmic bcl-2. Three out of 20 cases of squamous cell carcinoma were focally positive. None of the 10 Bowen disease cases and the 10 keratoacanthoma cases expressed bcl-2. 2. In BCC, bcl-2 immunoreactivity was great in the superficical subtypes which had an indolent growth variant, moderate in the circumscribed types, and weak in the infiltrative types which had aggressive growth variants. 3. Evaluation of the distribution of bcl-2 immunoreactive categories and MIB-1 grades revealed a negative correlation tendency, but no statistical significance. CONCLUSION: Our results suggest the presence of a protection mechanism from apoptosis mediated by bcl-2 protein involved in the neoplastic growth mechanism of BCC. In addition, the observed findings in the expression pattern of bcl-2 and MIB-1 in the BCC subtypes may be due to interaction between bcl-2 and other apoptotic-related oncogens.

BACKGROUND: The prevention of preterm deliveries still remains a major problem in ob-stetrics. The cause of preterm labor is poorly understood. Our purpose was to determine the risk factors for preterm labor associated with specific clinical and environmental factors. METHODS: Using a case-control design, 54 women with preterm labor and 134 controls with term labor, who were admitted to the department of Obstetrics and Gynecology, Dan- kook University Hospital from January, 1996 to August, 1996. The study groups were inte- rviewed and their medical records were reviewed. RESULTS: 1. There were no significant differences of maternal age, maternal weight at 20 weeks of gestation and maternal weight gain at the time of delivery. 2. There were no significant differences between housewives and working women. But the physical workload of the preterm labor group was significantly higher than the control group ( 16.0% vs. 4.0% ). 3. There were no significant differences in the smoking habit of mother or her husba- nd. The passive smoking of the preterm labor group was significantly higher than the con- trol group ( 43.8% vs. 26.8% ). 4. In vaginal bleeding at pregnancy, the preterm labor group was significantly higher than the control group ( 15.7% vs. 2.3% ). Especially, the third trimester vaginal bleeding of the preterm labor group was significantly higher than the control group. 5. There were no significant differences in the number of previous fullterm deliveries, previous abortions, and living children between two groups. The experience of the previous preterm deliveries of the preterm group was significantly higher than the control group ( 11. 5% vs. 0.8% ). 6. There were no significant differences of medications, consumption of alcohol, coffee, tea, green-tea, cola and nutritional beverages, the experiences of coitus, defecation numbers and accidents during pregnancy between two groups. 7. There were no significant differences in the plasma concentrations of hemoglobin, hematocrit, white blood cells, and in the blood pressure, and the body temperature between two groups. CONCLUSION: The risk factors of preterm labor were severe physical workload, vaginal bleeding at pregnancy, especially, the third trimester vaginal bleeding, and the experience of previous preterm deliveries.

Only several stages of conventional operation have been able to treat the open fracture of the limb with extensive bone and soft tissue loss. So we, authors, reviewed 25 cases of vascularized osteocutaneous fibulat transfer which were performed to the extensive bone defect of the limb and associated soft tissue injury(from May 13, 1982 to September 30, 1988). In 25 cases, one case was a chronic osteomyelitis combined pseudocarcinomatous epithelial hyperplasia of surrounding soft tissue, the other(24 cases) were the open comminuted fractures with the extensive bone and soft tissue loss of the limbs. The average size of the skin flap was 12.33 × 5.83cm, the average length of vascularized fibula was 16.5cm in length. The complications were fractures of grafted fibula, partial necrosis of both ends of the skin flap and uncontrolled infection of proximal end of grafted fibula. During postoperative period, the patency of the anastomoses were monitored by observing the color of the skin of buoy skin flap. The average amounts hypertrophied fibula at 12 months after operation were 20.6cm. And the following remarkable result were obtained. 1. With the uncontrolled bone infection, the vascularized osteocutaneous fibular transfer was able to be performed. 2. During the follow up period, the grafted fibula had been hypertrophied. 3. In roentgenogram, as compared with conventional bone graft, grafted bone was not resorbed and early united. 4. In adult, free fibula can be obtained and grafted as 23cm as long and the skin flap with fibula can be obtained and grafted as 21 × 7cm as large in or experience. 5. In the vascularized osteocutaneous fibula transfer, the patency of anastomoses was monitored indirectly by confirming skin flap. 6. The fractured fibula was united early by cast immobilization, and it was hypertrophied at the fracture site. 7. The vascularized osteocutaneous fibula transfer is also useful in application of the other long bones.
