serum factor가 $CD8^+$ T cell의 lymphokine 생산양상에 미치는 영향을 알아보기 위하여 13-20주령의 BAL B/C 마우스로 부터 $CD8^+$ T cell를 분리한 후 serum-containing medium과 serum-free medium을 사용하여 배양하였다. serum-free medium에서 배양한 $CD8^+$ T cell이 분비하는 lymphokine의 양은 serum-containg medium에서의 결과와는 달리 IL-2의 생산양은 낮았으나 IFNr의 생산양은 상당히 높았다. 이와같은 결과로 미루어 serum-derived factor가 $CD8^+$ T cell의 lymphokine 생산에 영향을 미친다고 생각된다.

The in-vitro immunomodulatory function of murine natural-killer (NK) cells induced by red-ginseng acidic polysaccharide (RGAP) in ovariectomized (OVX) rats was examined in this study. The IL-2-induced NK cell activity was significantly decreased in the OVX rats compared to the sham groups, but the normally induced NK cell activity was not. RGAP, however, increased the NK cell activity in both groups, and this effect involved iNOS expression. The inhibition of iNOS activity did not increase the NK cell cytotoxicity by RGAP in the OVX rats. The data that were obtained also demonstrated that the expression of iNOS was increased in the spleen of the OVX rats. These results indicate that RGAP increases the tumoricidal activity of the NK cell in the OVX rats, which is a primed or activated state of innate immune cells resulting from the changes in cytokine production induced by estrogen-deficient stress. Therefore, RGAP has a synergistic effect on the NK cell activities, which are regulated by the iNOS signals in OVX rats. This suggests that RGAP is useful for potential therapeutic strategies as a nutrient in regulating the NK cells in OVX rats.

Langerhans' cell histiocytosis is a rare disease showing proliferation of histiocytes in multiple organ system. Bone lesions are the most common radiolologic manifestation of Langerhans' cell hysticytosis. Extraskeletal sites of Langerhans' cell hystiocytosis involvement include the skin, lymph nodes, thymus, lungs, central nervous system, liver, pancrease, spleen, and bowel. The authors have experienced a case of Langerhans' cell histiocytosis which involved the skull. A 3-year-old female presented with soft tissue mass on right periorbital area. Plain skull X-ray showed punched out bone lesion. Computed tomography showed non-enhancing osteolytic lesion on right frontal skull. Histologic findings of an excised mass revealed pathologic features of Langerhans' cell histiocytosis.

Effects of kochujang (Korean red pepper soybean paste) extracts on tumor formation, natural killer (NK) cell activity in spleen and glutathione S-transferase (GST) activity in liver were investigated in the sarcoma-180 cell transplanted mice. Inhibitory effects of these samples on lung metastasis of colon 26-M3.1 cells were also evaluated in the Balb/c mice. The injection of methanol extracts from traditional kochujang I (TK I, 0-day fermented), II (TKII, 6-month fermented), commercial kochujang (CK, 1-month fermented) and red pepper powder (RPP) significantly reduced tumor formation in Balb/c mice (p<0.05), TKII decreased tumor growth by 46% compared with control, resulting in the smallest tumor weight. The transplantation of sarcoma-180 cells increased the spleen/body weight ratio of Balb/c mice, while TKI and TKll significantly decreased this index (p<0.05). The effect of TKll and CK, fermented kochujang, on the NK cell activity of splenocytes was higher than that of sarcoma-180 cells transplanted control group. TK II recovered the activity of hepatic GST that was decreased by the transplantation of sarcoma- 180 cells in to the mice. All kochujang-treated mice had significantly fewer lung metastatic colonies than control mice. TKII was the most effective in inhibiting lung metastasis of colon 26-M3.1 cells. These results indicated that optimally ripened (6-month) TK had more suppressive effects on tumor formation and lung metastasis than RPP and kochujang without fermentation and commercially prepared kochujang in mice.

Recently, there is a worldwide concern that a great number of man-made chemicals have a hormone-like action both in humans and in animals. DECD is developing screening programs using validated test systems to determine whether certain substances may have an effect in humans. In the present study. the establishment oj repeated-dose toxicity test method was tried. Flutamide. an anti-androgenic agent. was administered by gavage to Sprague-Dawley rats for 28 days at dose levels of 0. 0.5. 3 and 18 mg/kg body weight (10-15 rats/sex/group) to examine the effects on general findings. especially reproductive and endocrine parameters. Clinical signs. body weights, food consumption, and sexual cycle were checked and measured. For the gross and microscopic examinations. 10 rats/sex/group were sacrificed at the end of dosing period and the remaining animals of control and high dose groups (5 each) were sacrificed after 14 days recovery. Examinations for hematology and clinical chemistry were carried out at necropsy. There were no treatment-related changes in clinical signs. body weights, food consumption. gross necropsy. hematology and clinical chemistry at all doses of both sexes. The period and regularity of sexual cycle were not adversely affected at all doses by the test agent. At 18 mg/kg. both decreased weights of prostate, seminal vesicle and epididymis in males and increased weights of spleen and thymus in females were observed. In addition, decreased number of spermatids and sperms. increased serum testosterone concentration and increased incidence (100%) of interstitial cell hyperplasia were seen in males. At 18 mg/kg of the recovery group. decreased prostate weight. reduced sperm count and increased incidence (20%) of interstitial cell hyperplasia in males and increased thymus weight in females were observed. At 3 mg/kg. reduced sperm count was found. There were no adverse effects on parameters examined at 0.5 mg/kg of both sexes. The results suggested that the potential target organs of flutamide may be accessory sexual glands including testes for males and spleen and thymus for females. Taken together. this test method was found to be a useful screening test system for endocrine disrupting chemicals.

Abel et al. in Germany discovered a new dioxin-responsive gene, which has later been identified as rpt-1 (regulatory protein T-lymphocyte 1). While it is speculated that rpt-1 may play a role in signal transduction and carcinogenesis, its roles and functions remain unknown. The present study attempted to analyze functions of rpt-1 in human epithelial cells following the xenobiotic exposures. While German counterpart analyzed expressionn of rpt-1 in spleen and thymus cells from mouse and rat and characterizes molecular properties of the gene, our work mainly focused on analyzing function of rpt-1 in human skin cells. Expression of rpt-1 in human cells were analyzed by western and northern blot RT-PCR analysis. Expression of rpt-1 as well as Staf-50 in human cells with or without exposure to environmental pollutants were also analyzed by northern blot analysis, since Staf-50 is homologous with rpt-1 and found in human cells. To help study roles of rpt-1 in human cell system, retroviral vector system carrying rpt-1 gene under the CMV promoter were constructed and transfected. Cells overexpressing the gene after the transfection showed an increase of cell density and soft agar colony formations, as compared to the control cells, suggesting that rpt-1 may play a certain role in the transformation processes of human cells. While the expression of rpt-1 in spleen and thymus is known to be strong in the laboratory animals, both the basal and TCDD-induced expression of rpt-1 in the current cellular system remained insignificant. It is speculated that the expression pattern of rpt-1 may be tissue- and species-specific. The present study demonstrated a strong expression of rpt-1 protein in the brain of SD rat model. Since there is no previous report on the expression of rpt-1 in the brain tissue, the result may play a significant role in understanding dioxin-induced neurotoxicities in the future. The present study provides an opportunity to understand a role of rpt-1 in human cell system and suggest a possible lead and basis for the future study of dioxin-induced neurotoxicities.
