This study was conducted to investigate the effects of aerobic capacity on blood lactate changes after supramaximal progressive loaded exercise. The subjects were divided into Handball players(HB, n=6)group and Control(CT, n=6)group. All subjects exercised according to the protocol by bicycle erogometer. Blood lactate concentration was also measured during the test time. The RER values of CT group were relatively higher than that of HB group. In particular, the RER values of HR group at exercise 8 & 12min were significantly lower than that of CT group(P<0.05). The blood lactate concentration of HB group was significantly lower than that of CT group at 12min during the exercise(P<0.05). During the recovery times the blood lactate concentration of HB group were significantly lower than that of CT group. In addition, blood lactate clearance of HB group was also higher than that of CT group during the recovery time. From these results, it was suggested that lactate clearance during the supramaximal exercise may be affected by the level of endurance exercise performance.

Background: Recombinant IFN-beta products have been approved for the treatment of several diseases. Recently, Inbionet, Co. has successfully developed rhIFN-beta product, Genebeta. This study was performed in a purpose of confirming the biological activity of Genebeta by comparison with another recombinant IFN-beta, Beneserin which was already approved. Methods: In vitro antiporliferative activity, regulation of MHC class I expression, antiviral activity, regulation of natural killer cell cytotoxicity were studied for functional comparison of these two rhIFN-beta products. Results: Proliferation assay data showed that two recombinant IFN-beta inhibited T cell and Daudi cell proliferation to a similar extent. When antiviral activity was compared, there was no significant difference between them. The treatment of these two rhIFN-beta also resulted in a similar level of upregulation of class I expression on the surface of A549 cells. Cytotoxicity experiment against tumor cells revealed that both of rhIFN-beta could enhance NK cell cytotoxicity to comparable level. Conclusion: All comparison data indicated that rhIFN-beta products, Genebeta and Beneserin have comparable potentials as a biological response modifier.

이헌영,임의혁,김성걸,김진희,육은주,성자원,김병호,정형용,강대영,김영건 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

To investigate the effects of short-term administration of DDB(Biphenyl Dimethyl Dicarboxylate) for decreasing elevated serum aminotransferase levels in chronic liver diseases, authors applied 3 capsules of DDB per day at each meal time for 35 patients and compared with 35 patients treated with other conservative management. The following results were obtained. 1. Serum alanine aminotransferase (ALT) levels significantly decreased from 247.1± 180.0 IU/L of pretreatment level to 96.6±126.0 IU/L, 61.1±62.7 IU/L and 38.0±26.8 IU/L after 1, 3 and 6 months of treatment(p<0.05) and effective rates were observed in 60.0%, 71.4% and 88.6% of patients after 1, 3 and 6 months of treatment. 2. Serum aspartate aminotransferase (AST) levels decreased also significantly from 167.8±96.9 IU/L of pretreatment levels to 124.4±155.0 IU/L, 77.9±49.6 IU/L, 60.6± 46.9 IU/L after 1, 3 and 6 months of treatment(p<0.05), but decreasing pattern of serum AST was less significant than that of serum ALT. 3. No significant difference were observed in the serum ALT and AST changes according to the cause and duration of hepatitis. 4. No significant adverse effects were observed in whole patients treated with DDB. It is suggested that small dose administration of DDB is effective for decreasing serum aminotrans ferase levels in chronic liver disease in which other conservative management was not effective.

We report here on an unusual case of mucinous cystic tumor that was associated with endometriosis in the cecum. A 45-year-old woman was admitted to the hospital due to her 5 day history of right lower quadrant abdominal pain with a mild fever. A laparotomy was performed under the clinical impression of the tubo-ovarian abscess. A relatively well defined a multi-locular cystic mass (8.0×8.0×7.0 cm) filled with white-to-yellow thick mucoid material was found in the wall of the cecum. The right ovary and fallopian tube showed marked fibrous adhesion to the external surface of the cecal mass. A right hemicolectomy and salpingo-oophorectomy were performed. Histologically, the tumor was similar to those of ovarian borderline mucinous tumor, the intestinal type, and the mucinous epithelium of the tumor was merged with the endometriotic epithelium and stroma. On immunostaining, the CK20 positive mucinous epithelium was well demarcated from the CK7 endometriotic epithelium. This is the first case of low-grade mucinous cystic tumor intimately associated with intestinal endometriosis in the cecum.
