The 150 kDa protein of cyst fluid (CF) of Taenia solium metacestodes was purified by ammonium sulfate fractionation and Superose 6 HR gel filtration chromatography. The purified protein consisted of three subunits (15, 10 and 7 kDa proteins), which were analyzed with the use of a 7.5-15% gradient sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Immunofluorescence study was carried out by using immunize specific polyclonal antibody. Positive reactions were noticed at bladder walls, calcareous corpuscles, granules of cyst fluid and some host tissue surrounding the bladder wall of the metacestodes. These results suggest that the 150 kDa protein was secreted into host tissues, inducing immune responses in the host, and it may play important roles in the cellular physiology of the parasites.

PURPOSE: It is reported that 65% of diabetic male patients over 60 of their age are impotent. However, there is no report concerning the effect of serum glucose control on erectile dysfunction in diabetic patient. This study was performed to evaluate the effects of serum glucose control on erectile dysfunction. MATERIALS AMD METHODS: The development of Diabetes mellitus was defined that the serum glucose level was above 200mg/dL in random test at 25 weeks. We designed the experimental specimen into 3 groups; group I: diabetic OLETF (Otsuka Long Evans Tokushima Fatty) rats without blood sugar control (n=10), group II: diabetic OLETF rats with blood sugar control with 4U insulin subcutaneous injection daily from 26 to 46 weeks (n=10), group III: diabetic OLETF rats with blood sugar control with 10U insulin subcutaneous injection daily from 26 to 46 weeks (n=10). We estimated the collagen content of penile tunica albuginea with the scanning electron microscopy and observed the endothelial layers of corpus cavernosum with the transmission electron microscopy in each group. RESULTS: The serum glucose level was 249 +/- 4.1mg/dL, 234 +/- 2.7mg/dL, 215 +/- 3.0mg/dL respectively in group I, II, III, and decreased in order of group II, III. The differences among groups were statistically significant (p<0.05). The thickness of collagen bundles of penile tunica albuginea was 0.98 +/- 0.1 micrometer, 0.94 +/- 0.3 micrometer, 0.92 +/- 0.1 micrometer respectively in group I, II, III, and decreased in order of group II, III. The differences among groups were statistically significant (p<0.05). The endothelial layers of corpus cavernosum were decreased in II, III. CONCLUSIONS: The serum glucose control in diabetic rats decreases the collagen con tents in penile tunica albuginea and the endothelial layers of corpus cavernosum.

OBJECTIVE: The aims of this study were to analyze the natural history of patients with pseudomyxoma peritonei originated from mucinous ovarian tumor, evaluate clinical and pathologic variables, and review our experience with available therapeutic modalities. METHODS: Six patients were treated for pseudomyxoma peritonei originating from mucinous ovarian tumor at Severance Hospital between 1990 and 1998. The data were collected retrospectively and all charts were reviewed RESULTS: The mean age at diagnosis was 51 years, and most common symptoms were abdominal distension. Pseudomyxoma peritonei was found in association with five mucinous ovarian tumors of borderline malignancy, and one ovarian mucinous adenoma. All patients underwent surgical staging and cytoreduction, three patients received postoperative adjuvant chemotherapy and, of these, two developed recurrence. With respect to survival, all patients were alive, four were alive and free of disease, two were alive with disease at the end point of study. CONCLUSION: Pseudomyxoma peritonei is commonly associated with borderline mucinous ovarian tumors, and is a frequently relapsing and protracted disease. But aggressive and repeated debulking surgery is recommended for long survival.

The purposes of this study were to investigate importance level and performance frequency of the dietitians' duties and task elements, to examine the actual condition of education and need for education, to analyze the interrelation between their tasks and education, and to provide the direction of education for the contracted Business & Industry (B & I) foodservice dietitians. The task elements of receiving, ordering, HACCP management and directing serving process were done almost every day. In terms of the importance of tasks, food sanitation management, personnel sanitation management, receiving and ordering were high. Meanwhile, the computerization of their works was being carried out on the whole, showing a higher frequency in all the details of procurement management and accounting management, as well as task elements such as menu planning, leftover and food waste management, HACCP management and human resource management. In the past three years, HACCP management, cost management, planning work schedule and allotting a task, general business and sale bond management were increased most and rapidly. For the actual condition of education, dietitians got more education for the duty of sanitation, safe and facility/utility management than any other duty, while they did less education of procurement management and office management than others. Meanwhile, the education for sanitation, safe and facility/utility management and accounting management were very much required. For the relationships of frequency of duty and the necessity of education, seven task elements including food sanitation management were correlated positively. Eighteen tasks besides menu planning had a significant positive correlation between the importance of duties and the necessity of education.

8.Enzymatic N-glycan analysis of 31 kDa molecule in plerocercoid of Spirometra mansoni (sparganum) and its antigenicity after chemical oxidation.

A highly specific antigenic protein of 31 kDa from plerocercoid of Spirometra mansoni (sparganum) was obtained by gelatin affinity and Mono Q anion-exchange column chromatography. The purified 31 kDa protein was subjected to N-glycan enzymatic digestion for structural analysis. The relative electrophoretic mobility was analyzed by SDS-PAGE, before and after digestion. On SDS-PAGE after enzymatic digestion, the 31 kDa protein showed a molecular shift of approximately 2 kDa, which indicated the possession of complex N-linked oligosaccharides (N-glycosidase F sensitive) but not of high-mannose oligosaccharides (endo-beta-N-acetylglucosaminidase H, non-sensitive). Chemically periodated 31 kDa protein showed statistically non-significant changes with human sparganosis sera by enzyme linked immunosorbent assay (ELISA). Therefore, the dominant epitopes of the 31 kDa molecule in human sparganosis were found to be mainly polypeptide, while N-glycans of the antigenic molecule in sparganum was minimal in anti-carbohydrate antibody production.
