Usual interstitial pneumonia(UIP) is relatively rare disease of lung parenchyme under the age of 50. Lung cancer is reported to occur as a complication of UIP, but has not been reported in young age patient with UIP in Korea. A 35-year-old man was admitted to the hospital because of dyspnea, cough and mild fever. He had been suffered from dyspnea during 3 years. The dyspnea worsened recent 1 month ago. He had been treated with pneumonia at another hospital during 4 months before this admission. Chest radiographs and High resolution CT showed subpleural and basal dominant reticular opacities in both lung with no change until now. He was smoker and his occupation was car engine-man dealing with benzene. UIP is suspected by history and radiologic findings. Operation for open lung biopsy was performed to obtain lung specimen via video-assisted thoracoscopic surgery. Patient's pathologic examination showed UIP combined with adenocarcinoma in RLL superior segment and posterobasal segment and RLL lobectomy was done. After operation, the patient has been in cancer free condition so far. We report a case of UIP combined with lung cancer in young man with brief review of the literature.

We have visited the asylums in Chollapukdo for two months since March of 1985. We conducted a comparative study between the patients who has been previously hospitalized and who has not been hospitalized for psychiatric problems. We individually interviewed 489 patients using the interview schedule. The results are shown as follows: 1. The group who were young, single and highly educated have been more hospitalized than the groups who were old, married and little educated. However, no significant difference was made by sex and districts. 2. The group who lived alone or were deserted from the family has been rarely hospitalized. 3. The group, who has been entered the asylum by the family or who explained the reason as treatment, has been more hospitalized previously than the group entered by the others or who said that they came due to alcohol. 4. While the group who has been hospitalized showed tendency to accept having their psychiatric disorders, but the group who has not been hospitalized showed tendency to deny having their disorders. 5. The group who named their disorders psychoses or schizophrenia has been more hospitalized than the group who named them alcoholics. 6. The group hospitalized previously has been also treated in other ways besides psychiatric treatment, and chronic patients with the duration of more than three years has been relatively hospitalized previously. 7. While the group who has been previously hospitalized was relatively indicated for hospitalization, but the other group was not relatively indicated.

Construction equipment are of an variety in its type, size, and capability. Because of its prices being high, an appreciable effect on cost reduction is expected depending on the way of acquisition. It is therefore necessary to investigate all the modes of equipment acquisition before making a commitment. The different modes of acquisition and how they compare with each other economically constitute the object of this study.

In rare occasions in which aneurysmal neck clipping is nearly impossible, coating is employed. During the period from 1985 to 1992, 312 patients with aneurysm underwent surgery ; aneurysmal neck clipping were performed in 284 cases while coating only in 28. The reasons that coating was required were ; wide and broad neck in 13, perforators arising from the neck in 4, neck tearing during dissection in 3, very friable neck in 2, severe adhesion with surrounding structures in 3, and small aneurysm without enough room for clipping in 3. In twenty-three cases, cotton wisp and bioglue were used as coating materials. In another five cases, the aneurysmal wall was reinforced using Surgicel or Gelfoam. Patients were followed for 24 months on average of all the patients. Four had last contact Six died(4 due to rebleeding and 2 due to pneumonia). Fourteen were good and 4 were moderately disabled. There were no rebleeding incidences during first three months' follow-up after coating. We thus concluded that coating an aneurysm offers some protection from rebleeding, particularly when the rebleeding risk period is over.

We examined 1,856 patients who visited Won Kwang Neuropsychiatric hospital since July 11 of 1984(since the hospital opened) until June 11 of 1986. We researched diagnostic and other distributions of inpatients and outpatients. The study revealed as follows : 1. Of total patients males visited this hospital more than females as 52.7%. Most of them(67.1 %) resided in Iri, Iksan and Kimje. In the point of insurance, insured patients and uninsured patients except medicaids were 73 %. Males(60%) were more insured medically than females (55.4%). While insured patients relatively resided in urban area, but uninsured patients except medicaids did in rural area. 2. Of outpatients neurotic disorder was the most as 35.1%, secondly schizophrenic disorder and thirdly affective disorder, but of inpatients schizophrenic disorder was the most as 41.4%, secondly neurotic disorder thirdly affective disorder. 3. Alcohol abuse (98.2 %), paranoid disorder, convulsive disorder and child mental disorder were mostly found in males, but neurotic disorder (59 .6 %), affective disorder and other psychotic disorder were mostly found in females. 4. In unmarried ones schizophrenic disorder ( 43 .6 %), neurotic disorder, other psychotic disorder were common, but in married ones neurotic disorder (55.1 %), schizophrenic disorder, affective disorder were common. 5. On the distribution of age schizophrenic disorder was found the most in the twenties (28.4 %), next in the thirties and in the forties, but neurotic disorder was found the most in the thirties, next in the twenties and in the forties. 6. On the distribution of age at onset schizophrenic disorder develops mostly during the twenties (45.5 %), secondly during the teens and thirdly during the thirties, but neurotic disorder develops mostly during the thirties and the twenties (53.1 %). 7. On the duration of hospitalization 34.4% of the patients was hospitalized during less than 15 days, 22.0% during 60-90 days and 80.4% during less than 3 months. 8. In the result of treatment 41.2% of the patients was improved and 31.7% a little improved. In total 72.9% of the patients got helped therapeutically.

Transthyretin의 Glutathione 자동산화 촉진작용

박종근,정신,김재휴,김수한,강삼석,이제혁,안봉환 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.8

When reduced glutathione(GSH) was incubated at neutral pH and at 37°, its concentration decreased slowly with formation of oxidized glutathione(GSSG). Autooxidation of GSH was accelerated by Cu^(2+) and Hg^(2+), but not by other common mono-, di-, and tri-valent cations. Transthyretin was found to stimulate autooxidation of GSH in the presence or absence of Cu^(2+) and Hg^(2+). EDTA inhibited perfectly the autooxidation of GSH regardless of the presence of transthyretin. The stimulating activity of transthyretin was maximal at pH 7.0, declining progressively with increase or decrease of pH from 7.0. Sulfhydryl-blocking agents such as p-hydroxymercuribenzoic acid and Nethylmaleimide markedly inhibited the stimulating activity of transthyretin. Transthyretin stimulated autooxidation of other sulfhydryl compounds such as clithiothreitol and cysteine. However, it did not show a significant effect on autooxidation of sulfhydryl group of egg albumin and eye lens proteins. And transthyretin did not cause any oxidative change to thyroxine(T₄), 3, 5, 3Ltri iodo thyronine(T₃) and 3, 3: 5~triiodothpnine(rT₃) bound to it in the presence of GSH and Cu^(2+). The above results suggest that transthyretin may play a role in regulation of oxidized status of sulfhydryl groups in blood plasma and cerebrospinal fluid

Garlic (Allium sativum L.) is a widely distributed plant used in all parts of the world not only as a spice but also as a popular remedy for several thousand years Recent studies have shown that garlic components may regulate the many metabolism in liver. Therefore, the present work was undertaken to study the effect of garlicjuice, allicin fraction and heat-treated allicin fraction on the hepatic glutathione s-transferase and glutathione peroxidase which protect against toxic compound and lipid peroxide in liver. The results obtained were summarized as follows. By the treatment of garlic juice, glutathione s-transferase and glutathione peroxidase activity was increased in hepatic cytosolic fraction compare with control group. The enzyme activtiy is more increased by treatment with boiled garlic juice compared with fresh garlic juice in rats. The effect of allicin fraction and heat-treated allicin fraction on the hepatic glutathione s-transferase was observed that these components inhibited the enzyme activity in vitro, whereas the enzyme activity was strongly inhibited heat-treated allicin fraction than allicin fraction. These observation led us to conclude that the garlic components which are a stable substance in heat may regulate the hepatic glutathione s-transferase and glutathione peroxidase activity.

As turbulent flow include a complex physical process in the convective boundary layer(CBL), it is difficult to explain the physical phenomena exactly. Therefore, it is possible to explain the model in a simple and limited way. For the explanation of the CBL turbulence, enormous amounts of data are required concerning in CBL turbulence. A method to study the structure and characteristics of CBL is numerical simulation of important parts of the flow field i.e. through large eddy simulation(LES). In this study, turbulence in the CBL uniformly heated from below and topped by a layer of uniformly stratified fluid is investigated for flows by numerical simulation(LES). LES uses a finite-difference method to integrate the three-dimensional grid-volume-averaged Navier-Stokes equation for a Boussinesq fluid. In LES, the contribution of the large-carrying structures to momentum, heat and energy transfer are computed exactly, and only the effect of the smallest scales of turbulence is modeled. The purpose of this study is to analyze the velocity and temperature distributions in CBL turbulence in order to study the dispersion of atmospheric pollutant by LES.

The purpose of this study is to obtain basic infotmation on the wettability of pure-Al/Al₂O₃, Al-alloy/Cu, Al-alloy/Ni and Al-12%Si/Al₂O₃systems, by using the Sessile drop method. The wettability of Al alloy-melt on Al₂O₃increases with increasing temperature from 750℃ to 850℃ for Al-12%Si-y% (Cu, Zn and Mg) (y:0∼2)/Al₂O₃system, the contact angle decreases with increasing Cu, Zn and Mg content. The wettability of Al alloy on Cu and Ni-palte is better than that on Al₂O₃-plate : this is attributed to the interfacial reaction between the Al aiioy and the metal substrate.
