  • 수산물 폐기물을 이용하기 위하여 대롱 새우껍질에서 추출하여 만든 키토산을 마우스에 이식한 sarcoma 180을 이용하여 in vivo와 in vitro에서 항암 효과 및 면역기능에 미치는 영향에 대하여 실험하였다. 키토산의 sarcoma-180에 대한 고형암 성장 저지율을 40mg/kg투여시 63.84%의 저지율을 나타내었다. 수명 연장효과는 대조군에 비하여 키토산을 40mg/kg 투여하였을 때 26.84%로 그다지 높지 않았다. In vivo에서의 항암효과를 근거로 하여 in vitro에서는 sarco-ma-180에 대한 직접적인 세포의 독성 작용은 거의 없었다. 키토산은 30mg/kg과 40mg/kg을 투여시 혈중 백혈구수와 총복강세포수가 대조군에 비하여 다소 증가 하였고 장기인 간, 비장 및 흉선의 무게도 투여한 용량에 따라 증가하는 용량 의존성 반응을 보였다. 항체 유도염증 반응인 항체매개형 과민반응과 지연형 과민반응은 족척의 두께가 키토산에 의해 거의 정상 수준까지 회복되었다. Macrophage의 식작용에 미치는 영향은 phagocytic index 와 corrected phagocytic index에서 거의 차이가 없었고, 용혈성 반응 세포수(plaque forming cell, PFC)는 대조군에 비하여 PFC/$10^{7}$ spleen의 경우 18.88%와 31.83%로 다소 증가하였다.

  • Epoxidised soya bean oil (ESBO, 1000, 2000 or 4000 mg/kg) was orally administered to BALB/c mice daily for 28 consecutive days, and the control mice were exposed to vehicle (corn oil). Mice were immunized and challenged with sheep red blood cells (SRBC) or bovine serum albumin (BSA). In groups exposed to ESBO, the body weight gains and the relative lymphoid organ weights were not significantly changed as compared with control group. Secondary IgG antibody response to BSA was not significantly changed by ESBO, but plaque-forming cell (PFC) response to SRBC was significantly suppressed in mice treated with 4000 mg ESBO/kg/day. The mitogenic response of splenic B cells induced by LPS was not effected by ESBO in any of the groups. These results indicate that ESBO did not induce significant humoral immune response at a dose less than 2000 mg/kg/day in mice.

  • DW-116, [1-(5-fluoro-2-pyridyl)-6-fluoro-7-(4-methyl-1-piperazinyl)-1,4-dihydro-4-oxoquino-line-3-carboxylic acid hydrochloride}, is a new quinolone antibiotic with a broad antibacterial spectrum against G(+) and G(-) bacteria. DW-116 was evaluated for the immunomodulating activities, which is one of the efforts to investigate the mechanism of action related to the good in vivo antibacterial efficacy. The results of in vitro studies revealed there was no statistically significant increase in B and T lymphocyte proliferation. But the results of in vivo studies showed that the number of plaque forming cells (PFC), the amount of polyclonal antibodies and delayed-type hypersensitivity (DTH) were significantly increased after the repeat administration with 12 and 60 mg/kg of DW-116. Taken together, these results proposed that immunostimulting effect of DW-116 could be one of the action mechanisms for demonstrating in vivo antibacterial activities under these experimental conditions.

  • The effects of nalbuphine.HCI on the spontaneous locomotor activity and primary humoral immune response were investigated in ICR mice. Nalbuphine was intraperitoneally administered with the dose of 130, 260, 360 mg/kg in mice. The locomotor activity such as distance traveled was observed for 90min at 10min intervals. Nalbuphine showed the biphasic dose-response relationship on the spontaneous locomotor activity. IgM plaque forming cells(PFC) in splenocytes and IgM level in antiserum were significantly decreased depending on the dose of nalbuphine when nalbuphine was administered after the immunization, but slightly increased only at the low dose in the case of nabuphine administration after the immunization(SRBC).

  • Arabinoxylane과 PSP는 농도 의존적으로 비장세포의 증식과 IFN-${\gamma}$ 생산을 유도하였으며 특히, PSP는 IL-2, IL-4, IL-10의 생산도 유도하였다. 그리고, 항체생산 세포수를 나타내는 PFC은 11∼14%, 활성화된 T세포수를 나타내는 RFC은 9∼30% 증가하였다. Arabinoxylane은 T세포의 증식을 유도하지 못하였지만, PSP는 높은 농도에서 T세포의 증식반응을 유도하였다 Arabinofylane과 PSP는 비장세포에서 분리한 B세포의 증식을 유도하였고, 대식세포의 탐식능은약 20∼22%정도 증가하였다. 그리고, 농도 의존적으로 대식세포의 일산화질소 생산을 유도하였으며, TNF-$\alpha$와 IL-6의 생산을 현저하게 유도하였다. 특히, PSP는IL-1$\beta$의 생산도 유도하였다. 또한, 대식세포 표면의 주조직적합 복합체II(MHC Class II)의 발현을 유도하였다. 이상의 결과로 arabinoxylane과 PSP는 면역반응에 관여하는 T세포, B세포 그리고 대식 세포의 다양한 활성을 유도하는 효과가 있는 것으로 생각되어 면역기능을 강화하는 소재와, 노약자나 회복기 환자 등을 위한 특수 식이용 소재로서 사용이 가능한 것으로 생각된다.

  • Effects of plantago-mucilage A (P-MA) on the immune responses were studied in ICR mice. Mice were divided into 4 groups (10 mice/group), and P-MA at doses of 7, 21 and 63 mg/kg were orally administered to mice once a day for 21 consecutive days. Mice were immunized and challenged with sheep red blood cells (SRBC). P-MA at 63 mg/kg/day significantly increased the body weight gain and the relative weights of spleen and thymus, as compared with those in controls. However, there were no significant effects on liver weight due to P-MA treatment. Plaque forming cells (PFC) and hemagglutination (HA) titers to SRBC were significantly enhanced in mice dosed at 21 and 63 mg/kg/day P-MA, as compared with those in controls. Delayed-type hypersensitivity (DTH) reaction to SRBC, phagocyte activity and circulating leukocyte were also significantly increased in mice dosed at 63 mg/kg/day P-MA. These results demonstrate that P-MA markedly enhances both humoral immune and allergic reaction to SRBC at concentrations which don't act on the relative weight of liver.

  • The present study was undertaken to investigate the effect of biphenyl dimethyl idcarboxylate (PMC) on the humoral immunosuppression by ketoconazole (KCZ) in ICR mice. PMC at a dose of 6 mg/kg was administered orally to mice daily for 14 consecutive days. KCZ was suspended in RPMI 1640 medium and orally administered at 160 mg/kg/day 2 hrs after the administration of PMC. Mice were immunized an challenged with challenged red blood cells (SRBC). The results of the present study are summarized as follows; a gain of body weight and relative weights of spleen and liver were significantly increased by combination of PMC and KCZ, as compared with those in mice treated with KCZ alone. Splenic plaque forming cells (PFC) and hemagglutination (HA) titers to SRBC were greatly enhanced by the combination of PMC and KCZ, compared with treatment of KCZ alone. The elevation of serum glutamicpyruvic transminase (S-GPT) and total protein levels caused by KCZ were reduced to normal level by the combination of PMC and KCZ. In addition, lower serum albumin and A/G ratio were also increased to normal level. These findings indicate that PMC has a protective effect against KCZ-induced humoral immunosuppression.

  • These experiments were conducted to investigate the effects of Cervi cornu extract on lymphocyte blastogenesis in spleen, thymus, lymph node, born marrow cells of Balb/c mouse, haemagglutination reaction against sheep red blood cell (SRBC), plaque forming cell (PFC) assay against SRBC and IL-2 production. Lymphocyte blastogenesis was determined by $[^3H]-thymidine$ incorporation. According to the lymphcoyte blastogenesis test on the immune cell. Ceriv cornu extrat was showed a potent mitogenic activity on the spleen and lymph node cells, but had mild mitogenic activity on the thymus and born marrow cells. Mitogenic active component of Crevi cornu extract was identified to be materials where molecular weights are higher than 5,000 by membrane filteration method. Cervi cornu extrat was shown to increase mitogenic effect on the lipopolysaccharide (LPS)-stimulated spleen cells significantly, but decrease mitogenic effect on the Con A stimulated spleen cell at the concentration 0.3%, 1% and 3%. Ceriv cornu extract didn't show to be haemagglutination reaction and showed to inhibit the Con A-induced haemagglutination reaction against SREC. Result of SRBC-PEC test. Ceriv cornu extract significantly increase the number of PEC at the concentration of 0.1% and 1%. When IL-2 or IL-4 production was determined by proliferation of CTLL-2 cells. Ceriv cornu extract was not shown to stimulate the production of IL-2. From the above results, it is shown that Ceriv cornu extract increased antibody production by B cells, but nor IL-2 production by helper T cells.

  • The studies were conducted to investigate the combined effects of Tonics and Mitomycin C(MMC). The effects of Tonics and MMC on the proliferation of Molt-4 cells, human leukemic cell line, and activation of human lymphocytes were estimated by MTT colorimetric assays. Selected medicines among 9 kinds of Tonics by results of MTT assays were treated with MMC in mice. The Tonics itself enhanced the proliferation of Molt-4, but the anti-proliferative effect of MMC was not intercalated by the combined treatment of Tonic and MMC. Inhibitory action of MMC was augmented by Sa Kun Ja Tang(SKT). This result was due to the inhibition of DNA synthesis. Among 9 kinds of Tonics, Sip Jean Dae Bo Tang(SDT), Saeng Maek San(SMS) and Kwi Bi Tang(KBT) did not inhibit the action of MMC, but activated lymphocytes. When the mice were treated by MMC, the number of leukocytes was decreased significantly at the 1st day, but recovered at the 7th day. In the groups of MMC treated with SDT or KBT, the number of leukocytes was increased significantly than the group of MMC treated only at the 3rd day. Combined treatment of the Tonics(SDT, SMS) and MMC retained the body weight of mice at the level of normal mice. SDT, SMS and KBT did not change the number of plaque forming cells(PFC), but MMC treated group decreased the number of PFC. The combined treatment of MMC and SDT increased the number of PFC significantly than the MMC treated group. SDT, SMS and KBT did not influence the proliferation of T cells, but MMC treated group decreased the proliferation of T cells. The combined treatment of MMC and those tonics increased the T cell proliferation significantly than the MMC treated group. In conclusion, the results presented in this paper suggest that SDT, SMS and KBT can recover the side effects of MMC, such as weight loss, leukopenia and immunosuppresion, without any intercalating the anti-proliferative action of MMC in vivo.
