Depiartment of General Surgery, Cdlege of Medicine, Chung-AstB University With advancement of endoscopical instruments and technique, gallstone diseases can be managed with laparoscopic cholacystectomy which had rapidly and radically changed the surgicl treatment of gallstone diseases. The ideas of laparoacopic surgery was introduced 11y Germany gynecologist Serum, in 1967 and was first performed by French surgeon Mouret, Dtbois in 1987. Although many reports of early laparoscopic cholec,stectomy were excellent, many surgeons want to know the surgical results of laparoscopie cholcystectomy are enough good to perform comparing with the conventional cholecystectomy, especially in early complications and late complications. To know about above problems, we had clinical analysis of 300 patients with laparoscopic cholecystectomy who were admitted to the Departme$gt;tt of Surgery, Yong San Hospital, Chung Ang University from September 1990 to December 1991. The authors intentionally divided the observation periods into 3 groups. The first group including from 1st case to 100 cases, the second group f#om IOlth to 200th cases, the third group from 201th cases to 300th cases and observed periodical change of early and late complications fo laparoscopic cholecystectomy with accumulations kf surgical experience and improvement of surgical techniques. It's results were as follows. 1) The most prevalent age group was 4th decades arid the male to female ratio was 1 : 1.5 and had no periodical change. 2) Coexistent diseases were obesity of 30 cases(35%), hypertension of 20 cases(24%), pulmonary tuberculosis of 16 cases(19% ) in order. 3) The number of previous abdominal operations were appendectomy of 29 cases(38%), TAH of 18 cases(24%), C-section of 14 cases(l8%) in order. 4) The average operation time was 42.5 minutes and decreased compared with the past period. 5) The average postoperative hospitalization was 6 days. 6) The most predominant type in pathalogical clasfication was chronic cholecystitis(79%) and next common type was cholesterolosis(12%) 7) The most common postoperative complications mere bleeding of 3 cases(1%). bile leakage of 3 cases(1%) in order and had no periodical change. 8) The number of p41c),ts that needed Parentral'narcotics were as follows: Postoperative day: 163 casest54%)$gt; Pf.1D I: 154 cas(5L.3%), Pt7D 2: 96 cases(32.0%) and had no periodical change. 9) The frequency of parenteral narcotics were as follow: Postoperative day: 1.8, POD 1: 1.6, POD 2: 1.4 and had no periodical change. 10) According to oral cholecystogram, opacification correlated with operation time of laparoscopic cholecystectomy.

The purpose of this article is analyzing the economic impacts of abnormal climate on fall chinese cabbage farmers and consumers in Korea, with employing the equilibrium displacement model. Our results show that there were little difference in gross farm income, even though there were significant yield reductions due to abnormal climate changes. However periodic occurrences of abnormal climates caused serious damage to consumption levels which had declined by 10.6~17.1 percent with higher prices by 15.3~24.6 percent than normal climate years since 1990.

외상성 뇌실질 손상의 MRI

김성택,오창진,홍승관,문명선 대한신경외과학회 1991 Journal of Korean neurosurgical society Vol.20 No.8

The authors retrospectively analyzed the MRI findings of the 8 head-injured patients who had showed persistent unconsciousness and severe neurologic deficite after trauma. T2-weighted MR images disclosed high signal intensity lesions of various size and shape at lobar white matter and corpus callosum, subcortical gray matter, brain stem, and cerebral cortex, and assisted greatly in understanding the neurologic deficits of the corresponding patients. The lesions were mostly multiple and involved multiple structures CT's revealed in those patients only small hemorrhages, suspicious low densities, such nonspecific findings as slit ventricles and diffuse brain atrophy, or no abnormality at all. Post-traumatic parenchymatous lesions detected by MR images were either missed or quite underestimated on CT's. MRI was very superior to CT in the detection and anatomic localization of nonhemorrhagic intraaxial cerebral injuries, especially in the cases of small cortical contusions. CT is indicated in order to fastly detect intracranial hematomas which may need emergent surgical evacuation. If CT findings does not explain the neurologic degicits of the patients, especially in the late stage. MRI is indicated, MRI is expected to play a major role in the diagnosis of shear injuries involving white matter and brainstem where CT has been of little contribution or misleading.

This study was conducted to measure the enzyme activities and the amount of general components in Korean traditional soybean sauce which is commonly used to cook and meet the flavors of several Korean soups and dishes. Korean Meju, made of steamed soybeans removed of their fat components and wheat roasted and crushed, was used for the control groups in the experiment. The actual amount of general compounds and the enzyme activities were anlyzed using the designated amount of steamed Meju which was used as the experimental groups : The steamed soybeans were mixed with steamed wheat, barley, and crushed wheat, and the mixture was steamed for production of Meju which was used to make soybean sauce. The total amount of nitrogen and amino nitrogen were shown to be increased during fermentation of soybean sauce. The nitrogen and amino nitrogen were examined to be at the highest levels of amount ranged from 1.21 to 1.48% for nitrogen, and 520 to 650 mg for amino nitrogen in Meju, respectively. The amount of nitrogen was high in the order of the control group, wheat, barley, and crushed wheat. The amount of reduced sugars was measured : The levels of the reduced sugars were observed to be high 10 to 30 days aftermath, ranged from 8.90 to 10.6%, whereas the amount of the components was greatly reduced to 2.5% 120 days after production of soybean sauce. Ethanol was measured to be less than 0.68% 10 days after productoon of soybean sauce. However, the highest amount of ethanol was observed within the range from 1.44 to 2.72 %, of which the result was measured 90 days after production of soybean sauce. The amounts of both reduced sugars and ethanol were high in the control group, whereas the amount of the components was low in barleys. The darkness of colors was examined to be increased in soybean sauce. The optical density(O. D>) was 5.50 at 500 nm for the control group, and 1.75 to 2.68 for the experimental group. The optical density of the control group was showed lower than that of the experimental group. The intensity of color darkness was in the order of the control, barley, crushed wheat, and wheat. The percent ratio of the components was ranged from 18 to 19.5% for salinity, 14.37 to 19.7% for hardness in Meju. The pH ranged was befwean 4.73 and 5.72. The activity of protease was reached to the highest level at 60 days after production of soybean sauce, the activity of amylase, after liquefying and sacharifying of starch, was examined to be the highest 30 days aftermath.

가열 속도 및 반응 온도 그리고 혼합 비율에 따른 목재와 폴리프로펠렌 혼합물의 열분해 특성에 관한 연구를 TG와 GC-MS를 이용하여 수행하였다. 반응 온도 및 가열 속도가 증가할수록 액상 생성물은 감소하였으며 기상 생성물은 증가하였다. 폴리프로필렌과 목재의 혼합 열분해에 대한 액상 생성물의 수율이 최대가 되는 반응 온도는 500~600℃이었으며 반응온도 및 가열속도가 증가할수록 목재로부터의 이산화탄소 및 일산화탄소의 생성 수율은 감소하였다. The pyrolysis characteristics of wood and polypropylene(PP) mixtures have been studied by thermogravimetry(TG) and gas chromato-graph-mass spectrometry (GC-MS) with various heating rates, reaction temperatures and mixing ratios. As the reaction temperatures and heating rates increase, the yield of liquid products decreases, whereas that of gaseous products increases. The co-pyrolysis reaction temperature of wood and polypropylene mixtures for the maximum yield of liquids was 500∼600 ℃. The yields of carbon dioxide and carbon monoxide decrease as the reaction temperatures and heating rates increase.

The hemodynamic alterations were measured similtaneously by both invasive and non-invasive method in Korean mongrel dogs following the induction of acute myocardial ischemia by ligation of left coronary artery. By non-invasive method, the systolic time intervals were determined by similtaneous recordings of electrocardiogram, phonocardiogram and carotid arterial pulse tracing. By invasive method , direct measurements were made on heart rate, blood pressure, central venous pressure, pulmonary capollary wedge pressure and cardiac output. The results obtained by invasive and non-invasive STI method were as follows. 1. Among the hemodynamic changes measured by the invasive method, a marked elevation in PCWP(p<0.01) was observed at 30 minutes after the ligation of the coronary artery however no significant change was noted with other parameters. 2. There were no significant changes among STI parameters occuring acute myocardial ischemia and their parttens were similar to invasive measuring. 3. Comparing the data of invasive method with those of noninvasive STI method, the linear relationships were found. The correlation coefficient of CPP to dBP was 0.96, that of TI to PCWP, 0.91, and that of EVR to dT/sT,0.78. Analysis of data on the hemodynamic changes obtained by invasive and non-invasive STI methods confirmed the possibility that the non-invasive method may replace the invasive one for monitoring the hemodynamic changes in clinical management of acute myocardial ischemia.

Genetic Analysis of Cytotype Determinants in Q Strains of Korean Drosophila Melanogaster

Kim, Won Taik,Ki, Yong Sung,Sung, Kee Chang 한국유전학회 1990 Genes & Genomics Vol.12 No.4

In order to investigate the chromosomal effects for cytotype determination, two Q one M’, and Canton S(control) Strains were selected from Korean natural population and laboratory of Drosophila melanogaster. From the matings of the above straind with 'SKK' strain (i.g., Basc; In (2LR) SM1, Cy/In(2LR) bw^(VI) : In(3LR) TM3, Ser/Sb), twelve chromosome lines per strain were established under M or native cytotypes. Thereafter, the cytotypic change was checked with generations and the relative magnitude of chromosomal effects on the changes were examined. The results are as follows: Until the 12 generations, any cytotypic change was never detected in the lines derived from Canton S. In the lines from M’ strain, no changes to P cytotype were detected, except one case of a combination of X and 3rd chromosomes. But among the lines originated from Q strains, the cytotypes were found to be primarily determined by the genotype after only one or two generations, and to be subordinately affected by a maternal cytoplasm in some lines. In one Q strain, major cytotype determinations were detected in the lines including a wild X chromosome, and also detected in a combination of 2nd and 3rd chromosomes excluding a wild X chromosome. This figure are not consistent with the another Q strain, in which apparent change of to P cytotype was detected in only one combination of 2nd and 3rd chromosomes. Thus, this finding indicates that the cytotype determination in Q strains is dependent on chromosomal interaction and/or a particular chromosomal factor. The further molecular analysis will be provide a evidence on whether the above chromosomal effects in cytotype determination of Q strain are due to mainly by an interaction of P factors and/or KP elements in genome, by an absolute quantity of KP elements, or by a joint effect with another defective P elements between chromosomes.

The purpose of this study was to investigate the relationship between the increased serum calcium changes induced by short-term intravenous calcium infusion and the resultant subsequent changes on total and ionized calcium concentration [Ca_TOT] and [Ca^2+]level, and on bile acid changes in the T-tube bile. Ten patients underwent cholecystectomy, common duct exploration, and T-tube insertion. Serum and biliary calcium concentration were measured over an 7-hour period, before, during, and after a 4-hour intravenous infusion of 10% calcium gluconate. During the infusion, serum total calcium[Ca_TOT] increased from 2.17±0.27 mmol/L to 2.30±0.22 mmol/L and serum free ionized calcium[Ca^2+] increased from the preinfusion state, 1.29±0.10 mmol/L to 1.34±0.15 mmol/L. After the infusion, 60 minite later, biliary total calcium [Ca_TOT] increased from 1.54±0.23 to 1.95±0.37 mmol/L and biliary ionized calcium [Ca^2+] increased from 1.08±0.18 to 1.20±0.09 mmol/L. When the data pooled, increased serum total calcium[Ca_TOT] showed significant correlation with serum ionized calcium[Ca^2+] And also serum ionized calcium[Ca^2+] correlated with biliary total calcium[Ca_TOT] And as to bile acid, increased biliary ionized calcium[Ca^2+] related to decreased bile acid. These results support the hypothesis that calcium is freely permeable at biliary excretory system, and that serum ionized calcium level is one of the determinant elements of biliary calcium level.
