상완골 원위부 과간 골절은 소아에서는 매우 드물게 발생되는 골절로 대부분 주관절의 굴곡상태로 주관절 후방부에 직접적인 충격에 의해 발생하는 것으로 보고되고 있다. 전위가 없거나 경미한 경우 도수적 정복술 혹은 도수적 정복술 후 경피적 핀고정술을 시행하며, 전위가 심한 골절이거나 도수적 정복술이 불가능한 경우 관혈적 정복술 후 핀고정술을 시행하는 것으로 알려져 있다. 저자들은 전위된 상완골 원위부 과간 골절 환아 2예에서 각각 도수적 정복술과 관혈적 정복술 후 K 강선 고정술을 시행하여 만족한 결과를 얻었기에 보고하는 바이다. Intercondylar fractures of the distal humerus are very rare in children. The pattern of the fracture would suggest that the mechanism of injury involves a fall directly on the flexed elbow. Most agree that the undisplaced fracture can be managed conservatively. With increasing displacement and comminution, the opinions tend to differ. We suggest that closed reduction with percutaneous K wire pinning and open reduction with percutaneous K wire pinning offer a satisfactory methods by which to treat displaced intercondylar fracture in children.

Purpose : The purpose of this study was to evaluate the effect of nutritional support with enteral liquid supplement in cancer patients receving chemotherapy for possible benefit in nutritional, immunologic and golbal function of patients. Patients and Methods : From October 1995 to February 1997, 30 advanced cancer patients receving chemotherapy were divided two roups. The Nycare group, in addition to normal diet, Nucare^R enteral supplement was given for 1week right after chemotherapy for the duration of 2 chemotherapy cycles. Control group received only normal diet without parenteral fluid supplement for 2 chemotherapy cycles. Results : Median ages were 53 end 56 years for Nucare group and Contrl group respectively. Performance scores was less than 2 by ECOG scale. All patients were stage Ⅲ or Ⅳ. The physical parameters, such as weight, arm muscle circumference(AMC) and triceps skin fold(TSF) were decreased in both groups after 2 cycles of anticancer therapy. but it was less severe in Nucare group(p<0.05). Serum transferrin was maintained in mild deficit state in Nucare group, whereas it aggravated form mild to moderate deficit in Control group(p<0.05). Serum albumin level increased in Nucare group without statistical significance. but it decreased from normal to mild deficit in Control group. Serum total protein did not change significantly in Nucare group. but in Control group, serum total protein was decreased from 7.24±0.9 to 6.52±0.5(P<0.05). Total lymphocyte count did not change significantly in both groups. Conclusion : This study shows that the nutritional support with Nucare^R was effective in the prevention of nutritional deficit status in patients receving a nticancer chemotherapy.

This investigation was performed to estimate the proteins, chiefly collagen, obtained from 2 year old bovine gingival tissues. Proteins in samples were extracted by salt or pepsin digestion. Extracted collagens were treated with 0.1% SDS and 0.1% β-mercaptoethanol in 0.01M phosphate buffer, pH 7.0, and fractionated by SDS-agarose gel column chromatography and/or SDS-polyacrylamide gel electrophoresis. The hydroxyproline content of salt-soluble and pepsin-soluble collagen was also determined. The results were as follows : 1. The content of hydroxyproline in gingival tissues was 54㎍/mg dry weight. The content of hydroxyproline in salt-soluble collagen was high than that in pepsin-soluble. 2. From both of salt-soluble and pepsin-soluble collagen, the bands of α_1-, α_2-chain, and the unknown band corresponding to molecular weight 68,000 were separated by SDS-polyacrylamide gel electrophoresis. The another band of β-chain was also separated from the salt-soluble collagen. 3. The recollected fractions under the peaks of SDS-agarose gel column chromatography were separated by SDS-polyacrylamide gel electrophoresis into the bands of α_1-and α_2-chain around the area corresponding to the molecular weight of collagen.

La, Mg 이온교환 ZSM-5 촉매의 제조와 촉매 산강도에 따른 MTO 반응 활성의 검토

김한일,황종현,정태환,정석진 경희대학교 산학협력기술연구원 1997 산학협력기술연구논문집 Vol.3 No.-

The MTO(methanol to olefin) process that aims at the production of olefins from methanol has attracted research interest because of its possiblity as another source of raw material in petrochemical industries. However its reaction path is not only ceased at the point of olefin production but also much amount of by products such as paraffins and aromatics that accelerate carbon deposit are produced. Thus the catalyst deactivation is rapidly progressed. In order to maximize the selectivity from methanol to olefin, alkylation and aromatization should be excluded from reaction path through catalyst and process variables. In this viewpoint, as a solution of the former problem, various metals were substituted on HZSM-5 which is used in commercial MTO process. With NH_3 TPD and activity test, the correlation between reaction products and possibility in control of Bro¨nsted acid site which is reported as the reaction active site was investigated. In this study, ethylene and propylene are the target products because of their wide applicating field.

Separation, pressure and velocity distributions were studied fully developed two dimensinonal, incompressible flow over a flat airfoil in subsonic wind tunnel. Velocity and turbulence were measured with a two channel constant temperature hot wire anemometer and pressure with a pitot tube and pressure tranducer system. The experimental results were obtained as follow: (1) Turbulent intensity of shear layer just outside the separation point is considered to affect the size of separation bubble. (2) Static pressure coefficient is separated into three regions according to its value change. (3) Separation point is varied with the change of attack angle. (4) Velocity distributions and boundary layers normal to airfoil surface are changed as variation of attack angle of airfoil.

(1) Authors studied seasonal fluctuation of psychiatric admission preliminarily, based on data of admission to Pusan area for a 4 year period of 1960-1963, and obtained following impressions. (2) The rate of admission in Pusan area and its seasonal fluctuation appear quite similar to those reported by investigators for European, American and Japanese cities. Thus the admission increases in spring and reaches the maximum in May and then gradually decreases toward the end of year. (3) The data obtained by statistical analysis of the seasonal fluctuation in Pusan area were compared with those of foreign ones in order to observe how to be related to the latitude of the locality. It is the general tendency that the lower latitude showed increase of admission in earlier months of the year than the higher latitude did. (4) It is a impression that the admission of affective psychoses are more sensitive to the climatic factors than the schizophrenics. (5) It is conjured by the authors that the socio-cultural and economic factors should be considered to give an account of the seasonal fluctuation of psychiatric admission.

상완 신경총 마비는 쇄골 골절 후에 매우 드물게 발생하며, 대부분 많은 가골 형성을 동반한 쇄골의 중간1/3 부위 골절 불유합에서 발생한다. 골절의 치유 과정에서 과형성된 가골이 상완 신경총을 압박할 수 있으며, 감압술고 불유합에 대한 수술적 치료를 필요로 한다. 이에 저자들은 쇄골 골절 후 불유합과 과도한 가골 형성에 의해 발생된 지연성 상완 신경총 마비 환자를 치험 하였기에 보고하는 바이다. The brachial plexus palsies secondary to nonunion of the clavicle fracture are extremely rare. The nonunions are hypertrophic and usually in the middle third of the clavicle. Hypertrophic callus produced healing process will cause a compression of the neurovascular bundle. This lesion requires operative treatment for decompression of the brachial plexus and internal fixation of nonunion. We present a case of delayed brachial plexus palsy due to nonunion and excessive callus formation of a clavicular fracture.
