The truncated E1192-283 and E2384-649 genes of hepatitis C virus (HCV) linked to the gene for glutathione 5-transferase (GST) were constructed and their expressions were analyzed. The GST-E1192-283 fusion gene overexpressed the fusion protein in E. coli as a soluble form, while the GST-E1192-383 plasmid did not express expected fusion protein. The purified GST-E1192-283 fusion protein was efficiently cleaved by thrombin. More than 90% pure, HCV E1192-283 protein was obtained by GST-agarose chromatography. The truncated GST-E2384-649 fusion gene expressed the fusion protein mainly as an insoluble form, whereas the GST-E2384-740 did not express the fusion protein. The truncated GST-E1 182-283 and GST-E2384-649 fusion proteins reacted specifically with an HCV patient serum. In addition, mice immunized with either the purified E1192-283 or GST-E2384-649 proteins generated specific antibodies to each antigen. The results suggested that hydrophobic carboxyl portions of the E1 and E2 proteins might affect expression levels as well as the solubility of each fusion protein in bacteria. Also, the truncated E1 protein with Tyr-192 to Ser-283 contained antigenic epitope(s) which could be specifically recognized by an HCV patient serum.

BACKGROUND: This study was performed to develop a dietary self-efficacy questionnaire and to determine how dietary self-efficacy is related to selected biochemical markers and health-related quality of life in hemodialysis patients. METHODS: Participants included 172 patients who had been participating in a dialysis program for at least 6 months at two teaching hospitals. A questionnaire was used to assess socio-demographic factors, dialysis-related factors, dietary self-efficacy, and kidney disease quality of life (KDQOL). Serum levels of potassium and phosphorus and interdialytic weight gain were also measured. RESULTS: The internal reliability of dietary self-efficacy was 0.944 (Cronbach's alpha). Principal component analysis resulted in two factors, situational self-efficacy of compliance with dietary guidelines and self-efficacy of food choice. The correlation analysis showed a significant association between situational self-efficacy of compliance with dietary guidelines and serum potassium and KIDQOL. The average scores of situational self-efficacy of compliance with dietary guidelines and self-efficacy of food choice in the participants were 3.52+/-0.72 and 3.61+/-0.71 respectively. Multiple linear regression analysis showed that the situational self-efficacy of compliance with dietary guidelines was significantly associated with serum potassium level and KDQOL and self-efficacy of food choice was significantly associated with KDQOL. CONCLUSIONS: Based on our results, the developed dietary self-efficacy questionnaire may be a suitable survey tool for hemodialysis patients, which can play a role in predicting clinical indicators of patient and health-related quality of life. We recommend further research into clarifying whether the positive effects of increased dietary self-efficacy is maintained in long-term dialysis patients.

The intravenous administration of midazolam is widely used as sedative premedication for upper gastrointestinal endoscopy. We performed a study to evaluate the effectiveness and safety of midazoiam as premedication for upper gastrointestinal endoscopy. Between June 1995 and October 1995, 112 patients of diagnostic esophago-gastroduodenoseopy were enrolled in the study. The patients were recieved a bolus midazolam 0.~03mg/kg or placebo, followed by typical anesthesia. The blood pressure, pulse and oximeter values were monitored. The systolic blood pressure and heart rate were increased during endoscopy in compared with before premedication, and normalized immediately. There was no significant change of arterial oxygen saturation. Midazolam induced amnesia completely in 49.2% and partially in 27.2%, and all patients were recovered completely in 1 hour. The tolerance score is higher in the midazolam group as compared with the placebo group(p<0.05), and midazolam group would accept the same sedation for repeated endoscopies(p<0.01). We conclude that midazolam has beneficial effects as premedication for upper gastrointastinal endoscopy without significant altteration in cardiopulmonary parameters. This suggest that midazolam may be used more frequently as premedication, especially in the cases of repeated endoscopy.

BACKGROUND: The main function of melanocyte is known to protect the skin from hazardous sunlight. But, some investigators have claimed lately that melanocytes are also related to the immunologic role in the epidermis because these cells produce IL-1 activity and IL-1beta convertase activity, in vitro. OBJECTIVE: Our purposes were to investigate the effects of rIFN-gammaon the proliferation of melanocytes, melanin content, and the expression of HLA-DR antigen on melanocytes after a rIFN-gammaexposure. MEHTODS: The number of melanocytes, the melanin content, and the expression of HLA-DR antigen were evaluated on cultured human melanocytes according to a time sequence and various concentrations of rIFN-gamma. RESULTS: Antiproliferative activity on melanocytes was dependent on the exposure time and the concentration of rIFN-gamma. According to the exposure time and the concentration of rIFN-gamma, melanogenic acivity was inhibitd or stimulated. Normal melanocytes didn't express HLA-DR antigen, but when normal melanocytes were exposed to rIFN-gamma, the expression of HLA-DR antigen increased in a time-and concentration-dependent fashion. After the removal of rIFN - gammafrom the culture media, the expression of HLA-DR antigen on melanocytes also disappeared. CONCLUSION: In our study, melanocytes seem to be related to the immunologic role in the epidermis because these cells expressed HLA-DR antigen after rIFN-gammaexposure and we think that study could help to investigate between melanocytes and immunologic mechanisms in various inflammatory skin diseases.

Nevus lipomatosus cutaneus superficialis is a very rare skin disease which appears at birth or within the firat two decades of life. This uncommon condition is due to collections of ectopic fat cells within the upper and mid-dermis. There are two clinical forms. The first form is a lesion of zonal distribution, present from birth or childhood, usually on the buttocks or the lower back. The second form, a dome or sessile, papule, begins in adult life and is less restricted in distribution, and occurs also on the limbs Coalescence of soft, yellowish papules tends to form cerebriform plaques. The authors experienced two cases of typical nevus lipomatosus cutaneus superficialis. The first case was a 23-year male who had asymptomatic, soft, skin colored, and pea sized confluent nodules on the right lower back area since at birth. The second case was a 35-year female who had asymptomatic, multiple, soft, skin colored from rice to walnut sized confluent nodules on the coccygeal area which developed at the age of 27. Diagnosis was confirmed by clinical and histopathological findings.

Epidermolytic hyperkeratosis is a rare disease which is extremely variable in its severity. In some patients it may be so severe and generalized during the neonatal period as to be lifethreatening, in others, it is relatively inconspicuous. A bullous eruption is the characteristic finding of the epidermolytic hyperkeratosis The bullous episodes soon become less frequent and more localized and may eventually cesse, but continue into adult life after the age of 20 years in at least 20% of cases. A case of epidermolytic hyperkeratosis is represented. The patient was a 25-year-old male who had ichthyosiform erythroderma and the frequent episades of bullous eruption. The bullous eruption had been subsided under the treatment with oral penicillin administration. The histopathological features of the bullous lesion on his abdomen revealed the features of epidermolytic hyperkeratosis.
