  • Experiments were performed on mice to investigate the influences of doxycycine and ethanol on the immune responses. Doxycycline was injected intraperitoneally and ethanol was administered in the drinking water. Mice were sensitized and challenged with sheep red blood cells. Immune responses were evaluated by humoral immunity, cellular immunity, peripheral circulating white blood cell and phagocyte activity. Pathotoxicological influences were measured by serum protein and albumin. The weight of spleen, thymus and liver were measured. Doxycline and ethanol combined administration decreased the weight of thymus and spleen. Humoral and cellular immune response were reduced by doxycycline administration. Especially ethanol combined administration significantly reduced humoral and cellular immune response. Phagocyte activity was increased by ethanol combined administration and peripheral circulating white blood cell was significantly increased by ethanol adminstration. Ethanol combined administration decreased serum A/G ratio.

  • The clinical need for agents to modify immune response in the treatment of viral infection has lead to an increased interest in cellular and biochemical mechanisms regulating the immune response and to the development of a variety of biological and chemical substance with immunomodulatory activity. Inosiplex has shown antiviral activity in tissue culture, animal models and huamn studies through augmentation of immune response. However, the effect of inosiplex on immune response in animal has not been extensively analyzed, and the effect of inosiplex on immune response has been paradoxical depending on the time of administration of inosiplex in relation to that of antigen. Therefore, this study was undertaken to assess the effect of inosiplex on the immune response to sheep red blood cells(SRBC) in normal and viral infected mice. Inosiplex increased cellular immune response and plaque forming lymphocyte response to SRBC, decreased the recovery of S. typhimurium from infected mice spleen, and restored the depressed cellular immune response by measle and newcastle disease virus infections. All of the above results were observed only when inosiplex was given after immunization but did not when given before immunization. These results indicate that inosiplex stimulate the efferent are of immune response and may even block the afferent are, and suggest that inosiplex is a very promising drug in therapy of many viral infections.

  • The purpose of this experiment was to investigate both the immunomodulatory effect of evening primrose(EP) oil and the effects of EP oil on immunoregulation by cyclophosphamide in mice. EP oil at doses of 0.1, 0.2 and 0.4 ml/kg were orally administered to ICR male mice once daily for 28 consecutive days. Cyclophosphamide was injected intraperitoneally to ICR mice with a single dose of 5 mg/kg at 2 days before secondary immunization. Mice were sensitized and challenged with sheep red blood cells(S-RBC). Immnune responses were evaluated by humoral and cellular immune responses and non-specific immune response. The results of this study were summarized as follows; (1) The humoral immune responses such as hemagglutination titer(HA), hemolysin titer(HY), Arthus reaction and plaque forming cell(PFC) were significantly enhanced in the low dose EP oil administered groups(0.1 and 0.2 ml/kg). However, in the high dose EP oil administered group(0.4 ml/kg) the responses were significantly lowered. (2) In the case of cellular immune responses, delayed type hypersensitivity reaction(DTH) was significantly decreased in EP oil whereas rosette forming cell(RFC) was remarkably enhanced. (3) Activities of natural killer cells and phagocyte were generally enhanced in EP oil. In addition, serum albumin and globulin were also increased.

  • The bursa of Fabricius (BF) is a central humoral immune organ unique to birds. Four bursal peptides (BP-I, BP-II, BP-III, and BP-IV) have been isolated and identified from the BF. In this study, the immunoadjuvant activities of BPs I to IV were examined in mice immunized with H9N2 avian influenza virus (AIV) vaccine. The results suggested that BP-I effectively enhanced cell-mediated immune responses, increased the secretion of Th1 (interferon gamma)- and Th2 (interleukin-4)-type cytokines, and induced an improved cytotoxic T-lymphocyte (CTL) response to the H9N2 virus. BP-II mainly elevated specific antibody production, especially neutralizing antibodies, and increased Th1- and Th2-type cytokine secretion. BP-III had no significant effect on antibody production or cell-mediated immune responses compared to those in the control group. A strong immune response at both the humoral and cellular levels was induced by BP-IV. Furthermore, a virus challenge experiment followed by H&E staining revealed that BP-I and BP-II promoted removal of the virus and conferred protection in mouse lungs. BP-IV significantly reduced viral titers and histopathological changes and contributed to protection against H9N2 AIV challenge in mouse lungs. This study further elucidated the immunoadjuvant activities of BPs I to IV, providing a novel insight into immunoadjuvants for use in vaccine design.

  • Plasmid DNA vaccines encoding the hepatitis B virus (HBV) surface and hepatitis C virus (HCV) envelope antigens, respectively, were constructed, and attempt were made to find the possibility of a divalent vaccine against HBV and HCV. The expression of each plasmid in Cos-1 cells was confirmed using immunocytochemistry. To measure the induced immune response by these plasmids in vivo, female BALB/c mice were immunized intramuscularly with $100\;{\mu}g$ of either both or just one of the plasmids. Anti-HBV and HCV-specific antibodies and related cytokines were evaluated to investigate the generation of both humoral and cellular immune responses. As a result, specific anti-HBV and anti-HCV serum antibodies from mice immunized with these plasmids were observed using immunoblot. The levels of IL-2 and RANTES showing a $Th_{1}$ immune response were significantly increased, but there was no change in the level of IL-4 ($Th_{1}$ immune response) in any of the immunized groups. Compared with each plasmid DNA vaccine, the combined vaccine elicited similar immune responses in both humoral and cell-mediated immunities. These results suggest that the combined DNA vaccine can induce not only comparable immunity experimentally without antigenic interference, but also humoral and $Th_{1}$ dominant cellular immune responses. Therefore, they could serve as candidates for a simultaneous bivalent vaccine against HBV and HCV infections.
