1.Immunoblot findings of calcareous corpuscles binding proteins in cyst fluid of Taenia solium metacestodes.
The Korean Journal of Parasitology 2004;42(3):141-143
After collecting calcareous corpuscles from plerocercoid of Spirometra mansoni (sparganum), we evaluated the antigenic values of calcareous corpuscles binding proteins obtained from the cyst fluid of Taenia solium metacestodes. Immunoblot analysis revealed that cysticercosis patient sera strongly recognized 10 and 95 kDa calcareous corpuscles binding proteins. This result demonstrated that calcareous corpuscles are bound with major secretory antigenic proteins, which is possibly involved in the secretory pathways of the 10 and 95 kDa proteins presenting in the cyst fluid of T. solium metacestodes.

2.Modification of carbohydrate compositions of 31/36 kDa proteins of plerocercoids (sparganum) of Spirometra mansoni grown in different intermediate hosts.
The Korean Journal of Parasitology 2004;42(2):77-79
We purified specific 31/36 kDa antigenic molecules from sparganum in different intermediate hosts (snakes and mice) and analyzed their monosaccharide compositions. Compositional analysis showed that glucose and mannose concentrations were 2-3 fold higher in the 31/36 kDa molecule purified from snakes than those from mice. This result implies that antigenic glycoproteins of sparganum from snakes might be modified in mammalian sparganosis with respect to their carbohydrate composition.

3.A Comparison of Intravaginal Misoprostol and Dinoprostone for Cervical Ripening and Labor Induction in Term Pregnancy with Unfavorable Cervix.
Korean Journal of Obstetrics and Gynecology 2000;43(2):243-247
OBJECTIVE: To compare the efficacy and safety of intravaginal administerd misoprostol and PGE2 (dinoprostone) with oxytocin for inducing labor in women with an unfavorable cervix. METHODS: One hundred thirteen patients with indicated for labor induction and unfavorable cervix were randomly assigned and received either misoprostol 50microgram intravaginal with oxytocin intravenous injection or prostaglandin E2(dinoprostone) 3mg intravaginal with oxytocin intravenous injection. RESULTS: Thirty-nine subjects were assigned to misoprostol with oxytocin group and 74 to the PGE2 with oxytocin group. The median interval from induction to vaginal delivery was significantly shorter in the misoprostol with oxytocin group(1274+/-496 versus 1512+/-501 minutes)(p<0.001). No significant difference between two groups were mode of delivery, neonatal and maternal outcomes. CONCLUSION: Intravaginal misoprostol and PGE2 vaginal insert appear to be safe agents for cervical ripening and labor induction. Misoprostol is more effective than PGE2 vaginal insert with oxytocin injection.

4.Prognostic Implications of DNA Ploidy and S-phase Fraction Comparing with Other Prognostic Factors in Advanced Coloretal Adenocarcinomas .
Korean Journal of Pathology 1995;29(2):170-180
Dukes' stage of colorectal carcinoma has proven to be the most reliable and conventional prognostic indicator, followed by histological grade, lymph node metastases, tumor size, vascular and neural invasion. Flow cytometric analysis of DNA ploidy and S-phase fraciion (SPF) was examined to elucidate the correlations between sex, age, preoperative serum carcinoembryonic antigen (CEA) value, Dukes' stage, tumor site, size, gross features, histologic grade, and survival rate in 117 paraffin-embedded tissues of 68 cases of colorectal adenocarcinoma in Dukes' stage and 39 cases of colorectal adenoma and 10 cases of normal colonic mucosa. DNA aneuploidy was detected in 30 cases(44%) in adenocarcinomas and 6 cases (15%) in adenomas. Although the DNA ploidy and SPF did not show any correlation with sex, age, preoperative serum CEA level, Dukes' stage, tumor size, site and gross features, the incidence of DNA aneuploidy in the moderately differentiated adenocarcinomas was significantly higher than that of the well differentiated adenocarcinomas (p=0.0127) An apparent correlation was found between survival rate and DNA ploidy, Dukes' stage, histologic grade and preoperative serum CEA value. Dukes' stage was the most reliable prognostic indicator (p=0.0106), followed by histologic grade (p=0.0230), DNA aneuploidy (p=0.0251) and preoperative serum CEA level. (p=0.0369) In the patients with Dukes' stage C, DNA aneuploidy was more important than histologic grade as a prognostic indicator (p=0.0202). Although high SPF, greater than 21% in adenocarcinoma, was associated with the lower 5-year survival rate (12.0%), it was not statistically significant. These results suggest that DNA aneuploidy is regarded as biologic aggressiveness and considered as independent and/or dependent prognostic indicator along with Dukes' stage. However, prognostic utility of the SPF was not significant.

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.

Inflammatory linear verrucous epidermal nevus(ILVEN) is a rare variant of epidermal nevus characterized by an early age of onset, an unilateral pruritic inflammatory psoriasiform lesion, and relative refractoriness to treatment. It has been reported that ILVEN mainly occur in the lower extremities but develop in the upper extremities, neck and trunk. Herein, we present a case of ILVEN occurring in the left temporal scalp of a 32-year-old woman which, in our review of literature, has not been reported as a development site.

BACKGROUND: T cell mediated immune destruction is an important mechanism of liver injury in patients with chronic hepatitis C. Serum levels of soluble interleukin-2 receptor(sIL-2R) seem to serve as a marker for the T cell activation and progressive liver injury, This study examined serum levels of sIft-2R and hepatitis C virus (HCV) RNA in patients with chronic HCV infection to determine the correlation with the severity of chronic hepatocellular damage. METHODS: Serum levels of sIft-2R in 73 patients with HCV infection (chronic hepatitis 52, liver cirrhosis 9, hepatocellular carcinoma 12) and 40 healthy controls were measured by sandwich enzyme immunoassay (CELLFREE, T Cell Sciences, USA). HCV RNA was quantified by QUANTIPLEX(TM) HCV RNA 2.0 assay (Chiron, USA) with duplication. This assay is a sandwich nucleic acid hybridization procedure using branched DNA amplification for the quantitation of HCV RNA. RESULTS: The sIL-2R levels of 52 patients with chronic hepatitis (591.4+/-238.7U/mL), 9 with liver cirrhosis(949.4+/-721.9 U/mL), and 12 with hepatocellular carcinoma (1,167.4+/- 554.4 U/mL) were significantly higher than those of healthy controls(370.8+/-71.8 U/mL) (p<0.001). A progressive and significant increase occurred in sIL-2R levels with chronic hepatitis C, liver cirrhosis and hepatocellular carcinoma (HCC) in order (p(0.001). The HCV RNA was detected in all patients and the means of HCV viral load were 3.3 MEq/mL in chronic hepatitis, 2.8 MEq/mL in cirrhosis, and 3.7 MEq/mL in HCC. There was no significant correlation between HCV RNA and the severity of liver injury in chronic HCV infection. There were no correlations among sIL-2R, HCV RNA and serum ALT. CONCLUSIONS: These results suggest that chronic hepatocellular injury by HCV progress mainly by T cell mediated immune response, not by direct cytopathic injury. Also, sIL-2R can be useful as a marker in monitoring the patients with HCV infection at high risk of getting HCC.
