Activation of T cells for an immune response requires the participation of antigen presenting cells (APC) that express class II major histocompatibility complex gene products on their surface. Until recently, the macrophages have been considered to be the prime candidates for this role, but it is now recognized that other cells, including dendritic cells, B cells, activated T cells and endothelial cells, can present antigen effectively. Particularly, among them, dendritic cells (DC) are considered to be very efficient APC for various T -cell dependent immune responses in comparison with other types of APC. Nonlymphoid dendritic cells including Langerhans cells and interstitial dendritic cells strongly express the MHC class II products and have characteristic dendritic morphology. As far as we know, there is no study on the ontogeny of MHC class II -immunoreactive dendritic cells in the rat tongue. The aim of the present study is to investigate the ontogeny and morphological characterization of dendritic cells in the tongue of growing and developing rats. The distribution and morphology of the dendritic cells in the rat tongue were studied from the fetal 15 -day until 180 days after birth by means of immunocytochemical methods using anti -rat MHC class II monoclonal antibodies. The results were as follows: 1. MHC class II -immunoreactive dendritic cells were first found in the muscle layer of 17 -day fetus, and in the epithelium and lamina propria of the tongue at birth. 2. The number of MHC class II -immunoreactive dendritic cells was gradually increased with age, particularly, in the epithelium at 14th day, in the lamina propria at 14th day, and in the muscle layer at 21st day after birth. 3. Numbers of MHC class II -immunoreactive dendritic cells were higher in the dorsal part than in ventral part of the tongue at all developmental stages. Especially, dendritic cells were twice higher numbers in the epithelium, a little higher numbers in the lamina propria and almost same numbers in the muscle layer. 4. With age, shapes of MHC class II -immunoreactive dendritic cells were changed from round to dendritic and aggregated together. In conclusion, the above results suggest that the increases of the number and the changes of the morphology in MHC class II -immunoreactive dendritic cells, with age may influence on effects of cell -mediated immune responses.

Myoclonic-astatic epilepsy is an epileptic syndrome characterized bv the presence of myoclonic and astatic seizures. It is a rare generalized epilepsy of childhood and represents 1 to 2% of epilepsis in children up to the age of 9 years. In addition to myoclonic and astatic seizures, generalized tonic-clonic seizure, tonic seizure and absence status (non-convulsive status) can be combined. Non-convulsive status can produce apathetic and stuporous appearance. We represent 4-year-old boy who showed nonconvulsive status of myoclonic-astatic epilepsy with typical clinical and eleckoencephalographic characteristics.

This is the clinical studies of 171cases of acute poisoning in pediatric age which were visited at the emergency room of Han-gang Sacred Heart Hospital during the past 2 years and 5 months (Apr., 1974~Aug., 1976). The results were summerized as followings; 1. The incidence of acute poisoning among the emergency pediatric patients were 2.3%(171/7,310). 2. The sex ratio of male to female was 1.5:1. 3. The peak age group was 2 to 5 years of age (41.5%). 4. The peak incidence in a year was shown in August (17.5%) with prominence in summer season (47.3%). 5. The accidental poisoning was occured the most frequently from 4: 00 P.M. to 8:00P.M. during the day. 6. The motive of poisoning was mainly accidental causes (85.9%). 7. The most frequent causative substances were insecticides (29.8%) and then rodenticides (14%), D.D.S. (8.8%), reserpine (4.1%) were the next causes. 8. RH-787 poisoning were occured in 4 cases with the complication of diabetes mellitus 2 cases. 9. In poisonous plants, there were azalea (Rhododendron) poisoning (4 cases) and Gingko biloba Linne fruit poisoning (1 case).

PURPOSE: The incidence of adenocarcinoma of the uterine cervix is low. Traditionally, Low Dose R ate (LDR) brachytherapy has been used as a standard modality in the treatment for patients with carcinoma of the uterine cervix. The PURPOSE of this report is to evaluate the effects of the High dose rate (HL)R) brachytherapy in the patients with adenocarcinoma of the uterine cervix compared with the LDR. MATERIALS AND METHODS: From January 1971 to December 1992, 106 patients of adenocarcinoma of uterine cervix were treated with radiation therapy in the Department of Radiation Oncology, Yonsei University with curative intent. LDR brachytherapy was carried out on 35 patients and 7 1 patients w -re treated with HDR brachytherapy. In LDR Group, 8 patients were in stage I, 18 in stage II and 9 in st;ge III. External radiation therapy was delivered with 10 MV X-ray, daily 2 Gy fractionation, total dose 40-46 Gy (median 43 Gy), And LDR Radium intracavitary irradiation was performed with Henschke applicator, 22-59 Gy to point A (median 43 Gy). In HDR Group, there were 16 patients in stage I, 38 in stag <, II and 17 in stage III. The total dose of external radiation was 40-61 Gy(median 45 Gy), daily 1.8-2.0 3y. HDR Co-60 intracavitary irradiation was performed with RALS (Remote Afterloading System), 30-57 Gy (median 39 Gy) to point A, 3 times a week, 3 Gy per fraction. RESULTS: The 5-year overall survival rate in LDR Group was 72.9%, 6 1.9%, 45.0% in stage I, II, III, respectively and corresponding figures for HDR were 87.1%, 58.3%, 41.2%, respectively (p>0.05). There was no statistical difference in terms of the 5-year overall survival rate between HDR Group and LDR Group in a denocarcinoma of the uterine cervix. There was 1 1% of late complication rates in LDR Group and 27% in HDR Group. There were no prognostic factors compared HDR with LDR group. The incidence of the late complication rate in HDR Group stage II, III was higher than that in LDR Group ( 16.7% vs. 31.6% in stage II, 11. 1% vs. 35.3% in stage III, p>0.05). Although the incidence of radiation induced late complication rate was higher in HDR Group stage II and III patients than that in the LDR Group, statistical significance was not detected and within acceptable level. CONCLUSION: There was no difference in terms of 5-year survival rate and failure pattern in the patients with adenocarcinoma of the uterine cervix treated with HDR and LDR brachytherapy. Even late complication rates were higher in the HDR group it was an acceptable range. This retrospective study suggests that HDR brachytherapy seems to replace the LDR brachytherapy in the adenocarcinoma of the uterine cervix. However, further studies will be required to refine the dose rate effects.
