  • We have examined whether Soamsan 1 (SA 1) augment the inhibitory effect of oral administration of Soamsan (SA) on lung metastasis of mouse 816 melanoma cells. The inhibitory effect was slightly enhanced by increase in administration dosage of SA 1. SA 1 as well as SA inhibited effectively the lung metastasis regardless of the pretreatment with anti-mouseNK monoclonal antibody. However, in the case of 2-chloroadenosine-pretreated mice, the inhibitory effects of SA and SA 1 were decreased by 18 and 23%, respectively. In vitro stimulation of the mouse splenocytes with mitogens showed that SA or SA 1 significantly augmented the proliferation of mouse splenocytes. Especially, the activity was more prominent in the presence of a B cell mitogen. LPS than a T cell mitogen, Con A. These results suggest that oral administration of SA 1 or SA inhibited lung metastasis of B16 melanoma cells, possibly through a mechanism mediated by the activation of macrophages and B lymphocytes in the host immune system. However, SA 1 did not showed more significant augment of the activation of immune system than SA.

  • The purpose of this research was the comparative study of 3 kinds of black soybean on murine immune cells. The 3 kinds of black soybean are Glycine max Merr. with inner color-yellow (GY), Glycine max Merr. with inner color-greenish (GG) and Rhynchosia volubilis Lour. (RV). All of the black soybean increased the viability of murine thymocytes in vitro. The combined treatment of GY or GG and mitogen did not affect the viability of splenic T- and B-lymphocytes compared with mitogen-treated group, but the combined treatment of RV and mitogen increased their action compared with mitogen-treated group. Also, the 3 kinds of black soybean were given p.o. once a day for 7 days, respectively. RV increased the population of thymic-$CD8^+$, splenic-$CD8^+$ and $B220^+$ cells in vivo. Furthermore, GY and GG did not affect the phagocytic activity and the production of nitric oxide in peritoneal macrophages in vitro, but RV enhanced their action. These results suggest that immunopotentiative action of Rhynchosia volubilis Lour. is more potent than their of Glycine max Merr.

  • Two experiments involving 92 crossbred, 21 day old weaned pigs were used to evaluate the effect of glutamine supplement in a dietary or culture medium on lymphocyte proliferation. In Exp. 1, 88 pigs were fed diets supplemented with 0, 0.5, 1.0, or 1.5% glutamine for 28 days. Lymphocytes were prepared from peripheral blood mononuclear cells (PBMC), ileal Peyer's patches (PP), the mesenteric lymph node (MLN), and the spleen in each dietary supplement group on days 7, 14, or 28 postweaning. Lymphocytes were cultured at $37^{\circ}C$ for 72 h in a RPMI-1640 medium with or without mitogen-stimulated, and pulsed with 3Hthymidine for an additional 18 h. The stimulation index of PBMC proliferation in 1.0% dietary glutamine supplement group and both of the MLN and splenocytes proliferation in 1.5% dietary glutamine supplement group was significantly (p<0.05) increased at 14 days postweaning. In Exp. 2, four weaned pigs were fed a basal diet for 14 days. The 3H-thymidine incorporation of PBMC, PP, and MLN cells, incubated with 0.125 to 0.25 mM glutamine in culture medium were markedly enhanced with Con A-stimulated, however, the splenocyte proliferation was not affected in the addition of glutamine medium. These observations suggest that dietary glutamine supplement might enhance the lymphocyte proliferation of weaned pigs.

  • In fish both humoral and cell mediated immune responses have been reported whereas antibodies recognizing specific cellular populations have not yet been developed except for ones recognizing surface Ig molecules on B lymphocytes. Our aim was to develop and characterize monoclonal antibodies (Mabs) specific for the immune-related cells. Mabs were produced by fusion of myeloma cells (SP2/0) with Balb/c mouse spleen cells previously sensitized against Israeli carp (I. carp) kidney mononuclear cells. We obtained 44 Mabs positively reacting with I. carp kidney mononuclear cells and partially characterized 7 Mabs in the morphological and mitogen-based proliferative aspects. Fluorescence-activated cell sorter (FACS) analysis against I. carp kidney cells by using 7 different Mabs showed 80.3% for ICK 17-4, 65.1% for ICK 2-3, 64.1% for ICK 25-1, 67.5% for lCK 22-1, 70.8% for ICK 16-2, 76.8% for ICK 13-2, 79.7% for ICK II-I. Panning method was used for the isolation of Mabs specific mononuclear carp spleen cells followed by Wright's stain. The stained cell populations were identified as monocytes (ICK 17-4, ICK 2-3, ICK 25-1, ICK 22-1 and ICK 16-2), lymphocytes (ICK 11-1), and a mixed cell population of monocytes and lymphocytes (ICK 13-2). In cell proliferation assay, monocytes purified by ICK 17-4, 2-3 and 22-1 efficiently responded to Con A and PHA, while ones separated by ICK 25-1 did not react with any mitogens. Lymphocytes isolated by ICK 11-1, though it is not known whether they are T or B cells, were more responsive to Con A than PHA or LPS, suggesting that fish immune cells are somewhat different from mammalian cells in responding to mammalian T or B cell mitogens.

  • The effects of five lupane-triterpenoids from leaves of two Acanthopanax spp., chiisanogenin, chisanoside and $22{\alpha}-hydroxychiisanogenin$, acakoreoside A and acantrifoside A on the mitogen-induced proliferation were investigated in vitro. T cell proliferation (TCP) to concanavalin A (Con A) and the B cell proliferation (BCP) to lipopolysaccharide (LPS) were increased by chiisanogenin. TCP to Con A was significantly increased by chiisanoside and acankoreoside A, but not affected by chiisanogenin, $22{\alpha}-hydroxychiisanogenin$ and acantrifoside A, BCP to LPS was significantly increased by acankoreoside A and acantrifoside A, and slightly increased by chiisanoside, chiisanogenin and $22{\alpha}-hydroxychiisanogenin$.

  • Quaternary ammonium compounds(QACs)가 뱀장어의 면역반응에 미치는 영향을 측정하기 위해서 뱀장어의 혈액으로부터 림프구를 분리하여 증식능을 측정하였으며 또한 신장으로부터 탐식세포를 분리하여 탐식능, pinocytosis 및 superoxide anion활성능 등을 측정하였다. 림프구의 증식능은 mytogen(T-cell mitogen: ConA and PHA, B-cell mitogen: LPS) 및 QACs처리농도에 따라 별다른 차이를 보이지 않았다. 한편 신장 유래의 대식세포의 세균살해능은 QACs첨가농도에 따라 유의성 있게 증가되었다. 이러한 결과는 QACs이 작동대식세포로의 분화 및 활성을 촉진시켜서 탐식능, pinocytes 및 superoxide생성 등의 분비를 증가시킨 것으로 사료된다. 이상의 결과로 미루어 QACs가 어체의 면역반응에 관여하는 작용기전은 면역작동세포의 수를 증가시키기보다는 세포의 기능활성을 증강시킴을 알 수 있다.

  • Immunosuppressive potential of 65 kDa buffalo placental protein (bPP65) on B-cell proliferation in vitro and antibody response in vivo was evaluated. B-cell proliferation was estimated by measuring incorporation of tritiated thymidine in buffalo lymphocytes while primary antibody responses against phytohaemagglutinin (PHA) or keyhole limpet haemocyanin (KLH) were evaluated in mice. bPP65 suppressed proliferation of lipopolysaccharide (a B-cell specific mitogen)-stimulated buffalo lymphocytes in vitro indicating suppression of B-cells. This suppression was dose dependent over the protein concentration range $25-100 {\mu}g/ml$. Primary antibody responses in mice against PHA and KLH in presence of bPP65 were lower as compared to in its absence but these were not statistically significant. Amino acid composition data of bPP65 and BSA suggested that bPP65 is different from BSA.

  • This experiment was carried out to evaluate the immunological effects of Hwanhonsan extract. Hwanhonsan administration into mice enhanced Arthus reaction and DTH to sheep erythrocytes, and NK cells activities. Hwanhonsan extract augmented the DNA synthesis of mitogen-activated lymphocytes. Hwanhonsan also stimulated leucocyte migration ability, MIF and IL-2 production of T lymphocytes, but not IL-6 production of B cells. These results suggested that effect of Hwanhonsan might be chiefly due to nonspecific enhancement of NK cell activities and cell mediated immune responses.

  • The present study has been carried out to investigate the optimal condition on the blastogenesis of guinea pig lymphocytes. A microculture system in conjunction with a semiautomatic multiple sample harvester(SAMSH) was used to study the in vito optimal condition of guinea pig lymphocytes. Data were presented to show many variables that are Involved in studying the responses of guinea pig lymphocyte in a microculture system to the stimulation of Concanavalin A(Con A) and lipopolysaccharide (LPS). Analysis indicated that the conditions for optimal Con A as measured by incorporation of $^3H$-TdR include : (1) use of RPMI-1640 as culture medium, (2) use of $6{\mu}g$ of Con A, per culture, (3) use of $1{\times}10^6$ cells per culture. Conditions for optimal stimulation with LPS mitogen were similar to those used for Con A.
