This study included fifty two premature babies in whom EEG was performed at National Medical Center, from Jan. 1990 to Jun. 1991. clinical and EEG records of all subjects were analyzed and the following results were obtained. 1) The day of first EEG performed were;11 cases within 10 days, 20 cases from 11 days to days, 13 cases from 21 days to 30 days and 8 cases beyond 31 days. 2) The results of first EEG were; within normal limit in 34 cases, mild abnormality in 3 cases, moderate abnormality in 11 cases and marked abnormality in 4 cases. 3) The abnormal EEG ratio according to the sex was higher in female than in male (43.5% vs 27.6%). 4) The abnormal EEG ratio according to the gestational age was higher in shorter gestational age group than in longer gestational age group (40.9% under 32 weeks of G.A. vs 30.0% beyond 33 weeks of G.A.). 5) The abnormal EEG ratio according to the birth weight was not significant. 6) The abnormal EEG ratio according to the ventilator use was higher in used group than in not used group (38.5% vs 30.8%). 7) Combined diseases in 18 cases of abnormal EEG group were jaundice (14 cases), hyaline membrane disease (7 cases), asphyxia (4 cases), anemia (4 cases), hydrocephalus, sepsis, PDA, hypocalcemia, UTI and IVH. 8) The mean apgar score in abnormal EEG group was lower than normal EEG group both in one minute and five minute. 9) Two cases among 18 cases of abnormal EEG group showed abnormal brain sonographic findings, but one case among 34 cases of normal EEG group showed abnormal brain sonographic finding. 10) Ten cases were followed up with serial EEG, six cases of which were treated with anticonvulsant. We observed normalization of the EEG in 5 cases of anticonvulsant treated group.

A clinical study was made on 85 cases of prematurity under 37 weeks of gestational age who had history of blood transfusion during their admission at the National Medical Center from January 1989 to June 1992. The results were as follows: 1) Among 339 prematurity patients, 85 patients(25.1%) received blood transfusion once at least. 2) Male to female ratio was 1.13:1 and mean gestational age was 32.5 2.7weeks (range:25~36 weeks). 3) Most of blood transfusion(66/85 cases) were performed within first week of life. 4) 67 patients(78.8%) received blood transfusion 3 times or less. 5) Combined diseases were hyaline membrane disease(69.4%), jaundice(51.8%), sepsis(30.6%), PDA (14.1%), DIC (8.2%), pulmonary hemorrhage(7.1%), intraventricular hemorrhage (7.1%), pneumonia(7.1%) and hepatitis(4.7%). 6) Clinical manifestations at the time of blood transfusion were pallor (47.1%), decreased activity (44.7%), bradycardia (23.5%),apnea (21.2%), tachypnea (20.0%), lethargy (4.7%), poor weight gain (3.5%) and tachycardia (3.5%). 7) The values of hematocrit were significantly increased after transfusion(42.4 +/-7.2 vs 34.6 +/- 6.8vol%). 8) The episodes of bradycardia were significantly decreased after blood transfusion(0.09 +/- 0.39 vs 0.23+/- 0.78)while the episodes of apnea were not (0.15 +/-0.71 vs 0.27+/- 0.84).

Santonin-kainic acid complex was evaluated as a chemotherapeutic of the mass treatment of the Ascaris lumbricoides infection in Korea. The results could be summarized as follows: The negative conversion rate was 82.9% in average in 4 treated groups. Some variations of negative conversion rate among the treated groups were noticed. The egg reduciton rate was 97.7% in average and the results were rather uniform among the three evaluated groups. By the analysis of egg reduction, it seems that the lightly infected cases whose E.P.G. were under 5,000 were resistant to treatment with the less reduced egg output. After the treatment with this complex, the number of egg discharged cases were reduced to 1.84% and the average number of discharge eggs per incompletely treated or untreated cases were reduced to 12.5% compared with the level of before-treatment egg output. The successive observations of the pattern of worm expulsion after drug intake was made. The worms were mostly expelled in the stool within 3 days, and 58.9% of total expelled worms were collected within 24-hour stool. The minimum length of the immature worms expelled was 7.6cm. Among the 659 Ascaris collected in the first-day stool from 91 rural people, 8.5% were in the range of 7.6-12.2 cm-long, immature worms. The sex ratio, male: female= 0.69: 1.

BACKGROUND: It is now thought that the earliest manifestation of idiopathic pulmonary fibrosis is alveolitis, that is, an accumulation of inflammatory and immune effector cells within alveolar walls and spaces. Inflammatory cells including alveolar macrophages and resident normal pulmonary tissue cells participate through the release of many variable mediators such as inflammatory growth factors and cytokines, which contribute to tissue damage and finally cause chronic pulmonary inflammation and fibrosis. This study was performed to investigate the source and distribution pattern of transforming growth factor-beta1(TGF-beta1), platelet derived growth factor(PDGF), basic fibroblast growth factor(bFGF), interleukin 1(IL-1), interleukin 6(IL-6), tumor necrosis factor-alpha(TNF-alpha) and the role of these mediators on bleomycin(BLM)-induced pulmonary injury and fibrosis in rats. METHOD: Wistar rats were divided into three groups(control group, BML treated group, BML and vitamine E treated group). Animals were sacrifices periodically at 1, 2, 3, 4, 5, 7, 14, 21, 28 days after saline or BLM administration. The effects were compared to the results of bronchoalveolar lavage fluid analysis, light microscopic findings, immunohistochemical stains for six defferent mediators(TGF-beta1, PDGF, bFGF, IL-1, IL-6 and TNF-alpha) and mRNA in situ hybridization for TGF-beta1. RESULTS: IL-1 and IL-6 are maximally expressed at postbleomycin 1~7th day which are mainly produced by neutrophils and bronchiolar epithelium. It is thought that they induce recruitment of inflammatory cells at the injury site. The expression of IL-1 and IL-6 at the bronchiolar epithelium within 7th day is an indirect evidence of contribution of bronchiolar epithelial cells to promote and maintain the inflammatory and immune responses adjacent to the airways. TNF-alpha is mainly produced by neutrophils and bronchiolar epithelial cells during 1~5th day, alveolar macrophages during 7~28th day. At the earlier period, TNF-alpha causes recruitment of inflammatory cells at the injury site and later stimulates pulmonary fibrosis. The main secreting cells of TGF-beta1 are alveolar macrophages and bronchiolar epithelium and the target is pulmonary fibroblasts and extracellular matrix. TGF-beta1 and PDGF stimulate proliferation of pulmonary fibroblasts and TGF-beta1 and bFGF incite the fibroblasts to produce extracellular matrix. The vitamine E and BLM treated group shows few positive cells(p<0.05). CONCLUSION: After endothelial and epithelial injury, the neutrophils and bronchiolar epithelium secrete IL-1, IL-6, TNF-alpha which induce infiltration of many neutrophils. It is thought that variable enzymes and O2 radicals released by these neutrophils cause destruction of normal lung architecture and progression of pulmonary fibrosis. At the 7~28th day, TGF-beta1, PDGF, bFGF, TNF-alpha secreted by alveolar macrophages sting pulmonary fibroblasts into proliferating with increased production of extracellular matrix and finally, they make progression of pulmonary fibrosis. TNF-alpha compares quite important with TGF-beta1 to cause pulmonary fibrosis. Vitamine E seems to decrease the extent of BLM induced pulmonary fibrosis.

Appreciation of the normal variation of anterior and posterior diameter of the lumbar spinal canal under computerized axial tomogram may throw very important value on the diagnosis and treatment in lumbar spinal problems. The authers have measured the diameter of the lumbar spinal canal using EMI scanner CT 5005. The data was first based on the study of two cadaver lumbar spine and then the study of 268 normal Korean adults male 185, and female 83. The results were summerized as follows. 1. The diameter of the osseous segment was more narrow than articular segment in normal lumbar spinal canal, 2. The shape of lumbar spinal canal was oval in upper lumbar. but became triangular going down to the lower lumbar. There was no difference of diameter in sex. 4. The average diameter of anterior and posterior spinal canal was; L1 16.53± 0.18, L2 16.23± 0.215, L3 15.42± 0.26, L4 15.57± 0.43 and l% 17.7± 1.63mm respectively. 5. The average diameter of transverse spinal canal was; L1 23.31± 0.18, L2 23.76± 0.28, L3 24.78± 0.345, L4 26.07± 0.605 and L5 29.31± 1.19mm respectively. 6. It was more accurate to check out the pathology of the lumbar spinal canal using coinputerized axial tomogram than other method previously used.
