Strongyloides stercoralis is a nematodes and is prevalent in the tropical regions. In Korea, 6 cases have been reported in which the parasites were identified in feces. We report a case of hyperinfection syndrome with Strongyloides stercoralis confirmed in the tissue sections. A 52-year-old woman was admitted to the hospital because of generalized edema and weakness. She received steroid therapy for 30 years because of rheumatoid arthritis. One year ago, generalized edema and dyspnea were developed and she was diagnosed as minimal change nephrotic syndrome for which she received cyclosporin. On admission, she complained of generalized weakness and edema, multiple arthralgia and abdominal discomfort with nausea. The white-cell count was 14,600 without eosinophilia. A stool specimen was negative for occult blood, ova or parasites. Right lower quadrant abdominal pain and tenderness were developed, and the exploratory laparotomy was done under the impression of the acute appendicitis. An appendectomy with a biopsy of mesenteric lymph nodes was performed. From the 5th day after operation, the patient began to complain of the abdominal pain and constipation. Under the impression of adhesion bad formation, the laparotomy was done and disclosed that the proximal ileum was markedly dilated. On jejunotomy, a great amount of formed stool and barium was noticed in the proximal portion of small bowel. The jejunal tissue was biopsied. Grossly, the appendix was unremarkable. Microscopically, the inflammatory reaction was nearly absent, but in serosa, minute granulomas were found which contain a part of the parasite. Same feature was noted in the mesenteric lymph node. The biopsied jejunum contains numerous adult female, filariform and rhabdidiform larvae and eggs in the mucosa, submucosa and muscle wall. Their morphology was compatible with Strongyloides stercoralis. The patient died 5 days later in the state of multiple organ failure.

PURPOSE: This study aimed to investigate the job stress level of call center workers and figure out its relation with cognitive emotion regulation strategies as a cognitive coping strategy. METHODS: Data collection was conducted on 985 call center workers, working for K companies in Korea. ANOVA, t-test, Scheffe's test and multiple regression have been conducted for the data analysis using SAS 9.0 software. RESULTS: The total job stress score of subjects ranges Q25~49 (the lower 50%) whereas the score of job demand and job control ranges Q50~74 (the upper 50%), and its sectional job stress level is high. Since job stress is the major factor affecting cognitive emotion regulation strategies, it is shown that when the job stress score gets higher, the score of positive cognitive emotion regulation strategies gets decreased but the score of negative cognitive emotion regulation strategies, increased. CONCLUSION: Based on the results of this study, it is necessary to develop and apply an effective stress easing method for call center workers which reduces negative cognitive emotion regulation strategies and increases positive ones.

A considerable body of evidence has been accumulated suggesting that invasive squamous cell carcinoma develops from cervical intraepithelial neoplasia(CIN). Most women with invasive cancer of the cervix are from lower socioeconomic groups, have begun heterosexual activity early in life, marry early, are multiparous, and have many sexual partners. Although the epidemiology of the cervical cancer is known well, the pathogenesis of the cervical cancer from CIN is subtle yet. Apoptosis, including the programmed cell death, is important event in normal cell turnover and maintenance of adult tissues. Apoptosis exerts a homeostatic function in relation to tissues dynamics, as the steady state of continuously renewing tissues achieved by a balance between cell replication and cell death. The specific labelling of nick ends of fragmented DNA was used to see the apoptotic cells from normal epithelium of the cervix to invasive cervical cancer. The apoptotic cells were found normally in the parabasal layer of the epithelium. As the grade of CIN increase, the apoptotic cell were found in superficial of the cervix and number of the apoptotic cell were increased. In the cervical cancer, the apoptotic cell were found in the cancerous tissues more than in the normal epithelium. This results suggest that the cell proliferation is more important than the inhibition of the apoptosis in the carcinogenesis of the cervical cancer.

BACKGROUND: In our previous report, we observed the increaseed epidermal glucose concentrations and decreased hexokinase actiuities of diabetic patients which were ciimpared to those of normal individuals. And we considered that, there were some derrangement of lipid metabolism and glycolysis of diabetic epidermis. OBJECTIVES: This study wns planed to prove the above possible changes of lipid metabolism and glycolysis of diabetic epidermis. METHODS: The epidermal enzymatic activties of glucose-6-phophate dehydrogenase(G6PDH), phosphofructokinase(PFK), 1-glycerophosphate dehydrogenase(GOPDH) and b-hydroxybutyryl CoA dehydrogenase(HBDH) were assayed in the skin samples obtained friom diabetic patients and normal individuals by the fluorometric: method. RESULTS: Teh epidermal PFK activities of diabetic patients were decreased(3.49+1.35(mmole/hr/kg dry weight)) compared to that of normal individuals(5.00+0.56(mmcle/hr/kg dry weight))(p<0.05). The epidermal HBDH activities of diabetic patients were decreised(0.28+0.10(mole/hr/kg dry weight)) compared to that of normal individuals(0.49+0.20(mole/hr/kg dry weight)(p<0.01). The mean epidermal G6PDH activity of diabetic patients was decreasec. compased to that of normal individuals, but there was no statisical significance. The mean epidermal 3OPDH activittes of diabetic patients and normal individual; showed no significant difference. CONCLUSION: We consider that the decreased epidermal HBDH actiities of diabetic patients can decrease keton body formatiori, and the abnormal glycolysis can exist in the diabetic epidermis because the decreased enzymatic activities of diabetic epidermal PFK may decrease the velocity of glycolysis.

This study is to verify the protective ability against experimental Naegleria meningoencephalitis by immunization with Naegleria fowleri in mice. Naegleria fowleri, strain 0359, and Naegleria gruberi, strain EGB, were used in this study, and cultured in CGVS medium axenically. Inbred BALB/c mice, weighing about 20 g, were immunized by three intraperitoneal injection of 1 x 10(6) N. fowleri trophozoites at the interval of one week. This N. fowleri trophozoites antigen was fixed with 5 percent formaldehyde. N. fowleri trophozoites from culture were homogenized with sonicator at 4C as monitored by phase contrast microscopy, and their membrane and cell content preparations were made for the immunization of mice. Their inoculation dose in volume was equivalent to the 1 x 10(6) trophozoites in each injection for immunization. And N. gruberi trophozoites, which was fixed with 5 percent formaldehyde, were also used for immunization. Mice were inoculated intranasally with 5 x 10(4) N. fowleri trophozoites in a 5 microliter suspension under anesthesia by as intraperitoneal injection of about l mg secobarbiturate. Nervousness, rotation or sluggish behaviour were observed in the mice which were infected with N. fowleri. Necrotic lesion was demonstrated in the anterior portion of brain, especially in the olfactory lobe. The inflammatory cell infiltration with numerous N. fowleri trophozoites was noticed. This pathological changes were more extensive in the control than in the experimental groups. Mice were dead due to experimental primary amoebic meningoencephalitis that developed between 8 days and 23 days after inoculation. Mortality rate of the mice was low in the immunized experimental group. Mean survival time, which is the survival duration of mice from the infection to death, was prolonged significantly in the immunized mice except in the mice immunized with N. fowleri membrane. Even in the mice immunized with N. gruberi, survival time was delayed. In summary, the effectiveness of immunization is demonstrated in terms of protective immunity against Naegleria meningoencephalitis in mice.
