A 70-year-old woman with Parkinson disease was admitted to the emergency department with altered consciousness, fever and convulsive movements without experiencing withdrawal from antiparkinsonian medication. Six hours after the emergency department visit, the patient had a hyperpyrexia (>40℃) and a systolic blood pressure of 40 mmHg. There was no evidence of bacterial infection based on extensive workups. The patient was discharged without aggravation of Parkinson disease symptoms after treatment that included administration of dantrolene sodium, enforcement of continuous renal replacement therapy and cooling blankets. Malignant syndrome should be suspected if high fever occurs in Parkinson disease patients without evidence of a definitive infection.

We have experienced an unusual case of hemorrhagic renal cyst in the rt. kidney at 58 years old woman. The Rt. kidney was enlarged, and showed a few subcapsular ischemic areas The color of kidney was dark brown. As the cyst at lower pole of rt. kidney was dissected, hemorrhagic fluid visualized in the cystic cavity. The final pathologic finding was renal cyst associated with malignant change and renal cell carcinoma at another renal parenchyma. Herein, hemorrhagic renal cyst, a rare clinical entity, was reported with review of literatures.

The problem of carbon monoxide intoxication has been increasing since 1950s and it is still regarded as one of the most serious public health problem in Korea. If the patients survives the acute episode, elimination of carbon monoxide occurs in the rate of a halt-time of 3 to 4 hours. Nevertheless, there may remain after effect. Therefore, the present study was desinged to elucidate the change of myocardial tissue caused by acute carbon monoxide poisoning were evaluated by electrton microscopic observation of the severity of the mitochondrial swelling and cytochrome oxidase activity, which was demonstrated by histochemical staining with diaminobenzidine(DAB). Male Sprague-Dawley rats were exposed to the carbon monoxide of 1500 ppm for 150 minutes. They were divided into two groups ; one group were treated with hyperbaric oxygenation 15 minutes after carbon monoxide exposure, the other were not treated. Rats were sacrified 6 hours, 12 hours, 1 day, 3 days, 7days, 14 days, and 21 days after carbon monoxide exposure. The specimens were collected from the apex of the heart. In the group without hyperbaric oxygenation, mitochondrial swelling subsided 21 days after carbon monoxide exposure accompained by restoration of cytochrome oxidase activity. On the other hand, with hyperbaric oxygenation, healing process was shortened. Cytochrome oxidase activity was restored 7 days after carbon monoxide exposure.

Chitin and chitosan, polysaccharides made up of polymeric N-acetly glucosamine and D-glucosamine, are widely found in nature, forming the skeletons of crustaceans and insects, as well as the components of bacteria cell walls. Chitin and chitosan have been known to have many useful biological properties such as biocompatibility, biodegradability, antimicrobial activity, and wound healing. There properties have been known to be different depending on the degree of deacetylation of chitin, but it has not yet been fully evaluated. The purpose of this study was to evaluate the wound healing effect by the degree of deacetylation. Full-thickness skin incision was made on the backs of Sprague-Dawley rats. Three concentrations of powder, comprising 90% chitin, 50% chitin and 10% chitin, were separately embedded in the wounds of 3 rat groups. The wound-breaking strength and the collagen-hydroxyproline content of the skin at the wound sites were measured and histological examination was performed at postoperative 3, 7, and 10 days. The 50% chitin group had the highest tensile strenght of all groups. But the 50% chitin and 90% chitin groups had the lowest collagen hydroxyproline levels among all groups. The wounds treated with 50% chitin powder were completely reepithelialized and granulation tissue in the wound was observed 7 days after initial wounding. The arrangement of collagen fibers in the skin was ordered and similar to normal skin The 50% chitin powder is considered to be the most efficient wound healing accelerator among different concentrations of chitin powder.

PURPOSE: To assess the factors facilitating the prediction of the frequency of ethanol injections in successful renal cyst ablation. MATERIALS AND METHODS: We retrospectively reviewed the computed tomography and ultrasonography scans of 37 renal cysts. Two radiologists evaluated the characteristics of the presenting renal cysts, including size, calcification, septation, and lobulated configuration. Patients were divided into an “above-four” group and “below-three” group, according to the number of ethanol injections. RESULTS: Among the 37 renal cysts, six belonged to the “above-four” group and 31 to the “below-three” group. The mean volume of “above-four” group was 409.48 cc and that of the other group was 301.64 cc. Seven renal cysts included three belonging to the “above-four” group, which showed calcification. Twelve renal cysts presented a multilocular appearance with thin septa, and included a cyst classified under the “above-four” group. Three renal cysts had lobulated configuration, with one of them belonging to the “above-four” group. CONCLUSION No significant correlation was found among the different factors in the prediction of the frequency of renal cyst ablation. However, calcification was the most useful parameter for prediction of the number of renal cyst ablations needed.

The tibiofemoral angle is widely used for the diagnosis and treatment of knee problems, especially in degenerative joint disease of the knee. Among the various methods of measurement of tibiofemoral angle, Bauers method is being used most frequently. But measurement by Bauers method has seemed to show wide individual differences. Therefore we designed a ruler which can be used very easily for the measurement of the tibiofemoral angle with little differences between persons who measure the angle. To testify the advantages of our method, we selected 4 orthopedic surgeons and let them measure the tibiofemoral angles of 60 knees of 30 patients by Bauers method and by our method using the ruler. And 20 orthopedic surgeons measured tibiofemoval angles of 2 left knees by Bauers method and by our method using the ruler. The values of the tibiofemoral angle by two methods were compared and analyzed statistically. There was no significant differences between mean values. But, the tibiofemoral angles by our new method showed little differences among measurers. (P < 0.05)

BACKGROUND: V. vulnificus infection is found between May and October when the man who has hepatic disorder or immunity disorder eats raw shellfish and it causes the systemic symptoms such as sudden fever, chilling, shock and stupor and local skin lesions like blob and necrosis. This disease has 46~61% of fatality rate in spite of intensive treatment. This study conducts the examination of history, epidemic study, ingesting raw fish and bacteriologic investigation in the patients with similar clinical symptoms to the above and examines the diagnostic correlations. METHOD: It is conducted with 31 cases who admitted at emergency medical center of Chosun University Hospital from May of 1995 to September of 1998 and are suspected to have V. vulnificus infection. It analyze bacteriologic examination, the survey of residence, eating raw shellfish, hepatic disorder, alcohol drinking habits and skin lesion. RESULTS: 1)the rate of male and female is 15.5:1 and in the age, 18 cases are in fifties, seven ale in fifties and six are over sixties. 2) Clinically, V. vulnificus is detected in 20 of 31 cases which is suspected to have V. vulnificus i18c1ion and it is not detected in 5 cases. Other bacteria are detected in 6 cases and they include staphylococcus aureus, pseudomonas species, beta hemotytic streptococcus and E-coil. 3) In local distribution, Kohung has 10 cases, Shinan and Mokpo have six, Haenam and Kangjin have aye, Yongkwang and Muan have five, Naju and Yongam have five and Kwangju has one. 4) Eating fishes and raw shellfishes is found in 31 cases. In the kind of shellfishes, eating raw clam is 10 cases, raw thin-shelled surf calm is 8 cases, raw oyster is 5 cases and sliced raw fish is 4 cases and pickled sea floods ate 4 cases. 5) The cases with hepatic disorder are 23 and 15 Gases with heavy alcohol dunking Carrier are included. The cases with Diabetic Mellitus are four and those with pulmonary tuberculosis are two. Two cases have not basal diseases. 6) On the opinion of skin lesion, 20 cases show vesicular necrosis, 7 cases have dendriform erythema, 3 cases have papule and one case doesn't show clear skin lesion. CONCLUSION: When V. vulnificus infection is detected, it is fatal and those who have hepatic disorder or heavy alcohol drinking habit must avoid eating fishes and shellfishes raw in summer. It is important to have emergency treatment for the patient whose V. vulnificus infection is suspected. It is considered that the administration of initial antibiotics is effective by generalizing the clinical symptom, epidemic opinion and patient history even before the results of bacteriologic confirmed.
