The retrospective study was taken to study the serum transaminase level and it's correlation with several symptoms in human rotavirus gastroenteritis. 494 children, who admitted to the Department of Pediatrics in Dae Dong Hospital from January 1991 to December 1991 with chief complaints of waterdy diarrhea were included in studies. The 1st stool specimen on admission was tested for rotavirus Ag by ELLSA method. and than serum transaminase were checked. The results are as follows: 1) The peak incidence being between 6 months to 2 years in both group, but higher incidence was noted in Non-HRV group. Males are more common than females by ratio of about 2:1. 2) The major symptoms in order of frequency was diarrhea>dehydration>vomiting>coughing>fever in HRV group, diarrhea>dehydration=vomiting>fever>coughing in Non-HRV group. The incidence of dehydration and coughing in HRV group were higher than in Non-HRV group. 3) AST & ALT elevation above the normal value were 83.2% (213/256), 52.0% (133/256) in HRV group and 45.3% (116/238), 22.3% (57/238) in Non-HRV group. AST & ALT were significantly increased in HRV group than Non-HRV group (AST: p<0.05, ALT: p<0.05). 4) Mean concentration of AST & ALT were 46. 82, 38.06 in HRV group and 29.06, 21.23 in Non-HRV group. Mcan concentration of AST & ALT were significantly increased in HRV group than Non-HRV group (AST: p <0.05, ALT: p<0.05). 5) Mild dehydration is relatively more common in both group. The frequency were 56.6% (145/256) in HRV group, 47.5% (113/238) in Non-HRV group. The degree of dehydration was not correlated with serum transaminase level at each group(HRV group: p>0.05, Non-HRV group: p>0.05). 6) Duration of diarrhea for 4-5 days & 1-3 days were relatively more common in HRV group than Non-HRV group. The frequency were 36.3% (93/256) in HRV group and 34.9% (83/268) in Non-HRV group. The degree of diarrhea were not correlated with serum transaminase level at each group (HRV group: p>0.05, Non-HRV group: p>0.05). 7) No fever or duration of fever for 1-2 days were relatively more common in both group. The frequency were 39.9% (102/256), 37.5% (96/256) in HRV group and 38.2% (91/238), 42.5% (101/238) in Non-HRV group. The degree of fever was not correlated with serum transaminase level in HRV group, but correlated with Non-HRV group (HRV group: p>0.05, Non-HRV group: p<0.05).

Severe irradiation on head may result functional alterations of central nervous system. In this study, the irradiation effect on the cerebellar cortex following heavy X-irradiation on head was studied ultrastructurally. Radiation was produced with the linear accelerator ML-4MV[Mitshubishi Co.], and rats weighing about 200gm each were exposed their heads within the radiation areas of 30cm x 30cm, under the radiation distance of 80cm, and with the radiation depth of 1.2 cm. Radiation doses were 3,000rads or 6,000rads, respectively. Animals were sacrificed on 6 hours, 2 days or 6 days following the radiation. Under anesthesia, animals were perfused with 1% glutaraldehyde-1% paraformaldehyde solution. Two hours after the perfusion, brain were taken out and refixed over night in the perfusion fixative. Small blocks of cerebellar hemispheric cortices were refixed 2 hours in 2% osmium tetroxide solution. Fixed tissues were dehydrated in alcohol, embedded in araldite mixture, and cut with ultratome. Ultrathin sections were contrasted with uranyl acetate and lead citrate solutions, and observed with electron microscope. The results obstained were as follow : 1. On 6th hour following X-irradiations, many cerebellar cortical neurons showed increased electron densities, more complicated nuclear infoldings, depletion of synaptic vesicles, expansion of astroglial territories, etc. 2. On 2nd day following X-irradiations, many organelle-rich cells such as Purkinje cells and Golgi cells were darkly degenerated. Numerous myelin figures formed by the cisternal fusions of Golgi apparatus or granular endoplasmic reticula were observed. Cytoplasmic processes of activated astroglial cells were expanded around capillaries and between granule cells. 3. On 6th day following X-irradiations, morphology of neuropil and neurones in the cerebellar cortex was generally restored, except the expanded territories of astroglial cells. From the above results, it was concluded that the release ofneurotransmitters and transcapillary leakage of blood substance were occurred on 6 hours after heavy X-irradiations. And severe alterations were produced on 2 day after X-irradiation, but the condition was generally restored on 6th day following X-irradiation.

PURPOSE: Among the various surgical methods used for the effective treatment of cystic lesion in the jaws historically, decompression procedure has some of superior prognosis compare to direct enucleation. In order to propose the efficacy of decompression we performed this retrospective study to compare decompression procedure with one-stage enucleation in clinical results and prognosis. PATIENTS AND METHODS: We reviewed 175 patients who had been histopathologically diagnosed cystic lesions from 1996 to 2000 in our department. Patients who had been received decompression alone or secondary enucleation after decompression were 31 cases, and enucleation alone were 144 cases. The age and sex of the patients, the area, size, and histological type of the lesions, and detailed operation and complications including recurrence were investigated. The minimal follow-up period was 2 years. RESULTS: In 31cases of decompression, male patients were 22cases(71%) similar to male predilection(62.3%) in total 175 cases. Cystic lesions were developed evenly in all age groups totally. Decompression was mainly performed in teenagers but enucleation was used in elder decades. In decompression cases the lesions were located in mandibular posterior, maxillary posterior, mandibular anterior, and maxillary anterior in order, which had some differences in total and enucleation cases. In enucleation cases, less than 3cm in size was 77.1% but larger than 3cm was 93.5% in decompression cases. Histopathologically, dentigerous cysts(54.8%), unicystic ameloblastomas(16.1%), and odontogenic keratocysts(12.9%) were seen in decompression cases and no recurrence or metaplasia and infection was observed. On the other hand, permanent tooth loss, numbness, recurrence, and so on were accompanied after enucleation. CONCLUSION: Although decompression procedure has disadvantages such as many of visiting times and slow recovery of the surgical defect, decompression is the best choice of treatment for large cystic lesions of the jaws, because it prevents functional and cosmetic defect, allows bone regeneration, and makes easy secondary enucleation.

This experiment was performed to study the morphological responses of the thymic cortex of the mice after administration of BCG. Healthy adult mice weighing 25gm each were divided into normal and experimental groups. BCG[0.03X108-0.32X108 CFU] were injected subcutaneously to the animals every other day, and animals were sacrificed at 4 days, 1 week, 2 weeks and 8 weeks following the first injection. Thymus were removed immediately after sacrifice and transferred to cold phosphate buffered 2.5% glutaraldehyde-1.5% paraformaldehyde solution[pH 7.3], and cut into small pieces. Tissue samples were fixed for 2-3 hours in the same fixative, postfixed with phosphate buffered 1% osmium tetroxide solution[pH 7.3], dehydrated in a graded series of alcohol, and embedded in araldite mixture. Ultrathin sections stained with uranyl acetate and lead citrate were observed with a JEM 100CX-II electron microscope. The observed results were as follow : 1. In the early BCG treated groups, a few eosinophile leucocytes were observed, but more eosinophils were observed in later groups. Some elongated and bar-shaped lysosomes with eletron lucent gap were often obserced in the macrophages. 2. Cortical population of thymocytes in the thymus were reduced, whereas territoris of the epithelial reticular cells were expanded especially in 2 weeks and 8 weeks groups. Some portion of the thymic cortex exhibited large intercellular spaces, and a few nuclear bodies filled with materials of medium density were observed in the epithelial reticular cells. 3. In the 8 weeks groups, macrophages, plasma cells and eosinopile leucocytes and developing eosinophile leucocytes were often observed in the thymic cortex. Distended cisternae of granular endoplasmic reticula and newly forming prosecretory granulses in the Golgi complex were ovserved in som plasma cells. From the above results, it was suggested that repeated treatment with BCG could induce disturb the maturation and differentiation of the T lymphocytes. In turn, BCG, if repeatedly injected, may disturb the immunological medchanism.

OBJECT: The nonstress test(NST) and complete biophysical profile(BPP) were compared with the rapid biophysical profile(BPP) in order to evaluate the efficacy of the rapid BPP, namely, the combination of amniotic fluid index(AFI) and sound-provoked fetal movement(SPFM) detected by ultrasound, in predicting intrapartum fetal distress in high-risk pregnancies. STUDY DESIGN: From JAN 9th 2000, through JAN 5th 2001, the prospective study of diagnostic tests was conducted on a total of 91 high-risk singleton pregnancies, undergoing antepartum assessment both the standard NST and the new rapid BPP(including other indices of complete BPP). The diagnostic indices of the NST, rapid BPP and complete BPP were calculated in term of predicting intrapartum fetal distress. RESULT: The sensitivity, specificity, negative predictive value, and positive predictive value of NST were 50.00, 94.81, 96.05, and 42.86% respectively, and those of rapid BPP were 75.00, 98.53, 98.53, and 75.00%, and those of complete BPP were 83.33, 98.72, 98.72, and 83.33%, as well. In addition, the efficiency of NST, rapid BPP, and complete BPP were 91.57%, 97.22% and 97.62% respectively. CONCLUSIONS: The rapid BPP is an effective and reliable predictor of intrapartum fetal distress with high-risk pregnancies. Moreover, it may be inexpensive and less time-consuming method.
