In order to investigate the effect of Row ginseng (Ra. G.; from $K{\acute{u}}msan$ province, Korea), White ginseng (W.G.; from $K{\acute{u}}msan$ province, Korea), and Red ginseng (Re. G.; form $K{\acute{u}}msan$ province, Korea) on immune response, the author used ICR mice having a body weight of about 20g as experimental animals dividing them into four groups-Saline, Ra. G, W.G., Re. G group. Delayed type hypersensitivity(DTH) and rosette forming cells(RFC) for cell-mediated immune response, hemagglutinin(HA) titers, hemolysin (HL) titers for humoral immune response were measured at 24 hours after challenge, The results were summarized as follows: 1) DTH was increased in all of the treated group as compared with the Saline group, with statistical significance(W.G.> Re. G. > Ra. G.). 2) RFC was increased in all of the treated group as compared with the Saline group, with statistical significance(W.G. > Re. G. > Ra. G.). 3) HA titer was increased in all of the treated group as compared with the Saline group, with statistical significance (Re. G.> W. G.> Ra. G.). 4) HL titer was increased in all of the treated group as compared with the Saline group, with statistical significance (Re. G. > W. G.> Ra. G.). Through the experimental study in ICR mice, these findings suggest that Raw ginseng, White ginseng and Red ginseng enhance both cell-mediated and humoral immune response with statistical significance.

As many crude drugs are used in the oriental medical field problems on the side effects of these drugs come to the front. To conduct delayed-type hypersensitivity we selected 29 kinds of drugs used frequently for therapeutic agents in oriental medical hospitals (Table I). The cell-mediated immune response was evaluated by measuring the foot pad swelling reaction and humoral immune response by measuring the antibody formation to these crude drugs. Mice were given these drugs intraperioneally for sensitization and challenged with same drug as used for sensitization respectively by intral dermal injection on the left and righ hind foot pad 4 days after senstization and then the foot pads were measured with the dial micrometer. The results were as follow; 1) Gentianae Scabrae Radix, Arecae Semen, Corydalis Tuber, and Paeoniae Radix were significant as delayed-type hypersensitivity inducers. 2) None of the crude drugs tested had effect on the induction of humoral immune response.

Experiments were performed on mice to investigate the effect of panax ginseng extracts on the immunotoxicity of ethanol. Immune response were evaluated by antibody production, Arthus reaction, delayed type hypersensitivity (DTH), Rosette froming cell (RFC) and macrophage activity in mice, sensitized and challenged with sheep red blood cells. The weight of liver, spleen and thymus were measured. Following results obtained in this experiment. The exposure of ethanol decreased humoral and cellular immune response, the body weight and macrophage activity. Ginseng extracts such as ethanol extract, petroleum ether extract and n-butanol fraction were significantly increased the body weight. The administration of ginseng ethanol extract and ginseng petroleum ether extract were restored or increased humoral and cellular immune response. Macrophage activity was decreased by ethanol, but restored by the ginseng extracts.

Bacterial DNA containing immunostimulatory CpG motifs can stimulate antigen-presenting cells to express co-stimulatory molecules and to produce various cytokines in vivo and in vitro. In this study, we fragmented macromolecular E.coli genomic DNA with DNase I, and analyzed the ability of the resulting DNA fragments to induce the NF-${\kappa}B$ activation and humoral immune response. Furthermore, using computational analysis and luciferase assay for synthetic ODNs based on the sequence of the immunostimulatory DNA fragments (DF-ODNs), an active component of DF-ODNs sequences was investigated. Experimental results demonstrated that DF-ODN is optimal for the NF-${\kappa}B$-responsive promoter activation in the mouse macrophage cell line and the humoral immune response in vivo. In agreement with the activity of the DF-ODNs processed by DNase I, a synthetic ODN based on the DF-ODN sequences is potent at inducing IL-12 mRNA expression in primary dendritic cells. These results suggest that the discovery and characterization of a highly active natural CpG-ODN may be achieved by the analyses of bacterial DNA fragments generated by a nuclease activity.

In order to investigate the of effects of nalbuphine on immune system in mice, we examined the various immunological parameters. After single oral administration of nalbuphine (130, 260, 390 mg/kg, i.p.) to female ICR mite, the weights of bodies and organs (thymus, spleen, liver, kidney), and hematological parameters were examined on day 2, 4, 6, and 8. The increased rate of body weight, relative weight of organ, and hematological parameters in nalbuphine -treated groups, were not significantly changed when compared with control group. However, number of WBC was decreased by the treatment of nalbuphine. To assess the effects of nalbuphine on humoral immune responses, splenic IgM plaque forming cell (PFC) and serum IgM were assayed. When nalbuphine wat administered after immunization with SRBC, but not before immunization, splenic IgM PFC and ,serum IgM level against SRBC were significantly lowered in a dole -dependent manner. These results indicate that the suppressive effects of nalbuphine on primary humoral immune response may be dependent on the timing of its administration relative to the initial antigenic sensitization.

In order to investigate the effects of Insamyangwee Tang on cell-mediated and humoral immune response, solid extract of Insamyangwee Tang (sample A), mixture of individual solid extract of Insamyangwee Tang (sample B) were administered orally for 14 days. The auther used ICR mice having a body weight of about 20-22g as experimental animals dividing them into three groups-Saline, Sample A and Sample B group. All of the mice were sensitized i.v. with $10^8$ sheep red blood cells(SRBC) and challenged i.d. with $10^8$ SRBC 4 days later. Such immune responses as delayed-type hypersensitivity(DTH), rosette forming cells(RFC), hemagglutinin titers(HA titers) and hemolysin titers(HL titers) were measured at 24 hours after challenge. The results were as follow: 1. DTH in Sample A & Sample B group was increased, as compared with Saline group, with satistical significance. 2. RFC in Sample A & Sample B group were increased, as compared with Saline group, with statistical significance. 3. HA titers in Sample A & Sample B group were not increased, as compared with Saline group, with statistical significance. 4. HL titers were increased just only in Sample A group with statistical significance. The inference from the above results is that Sample A group is better than Sample B group, and Insamyangwee Tang enhance the cell-mediated and humoral immune response.

In this paper, we propose and analyze three viral infection models with humoral immunity including an eclipse stage of infected cells. The incidence rate of infection is represented by bilinear incidence and saturated incidence in the first and second models, respectively, while it is given by a more general function in the third one. The neutralization rate of viruses is giv0en by bilinear form in the first two models, while it is given by a general function in the third one. For each model, we have derived two threshold parameters, the basic infection reproduction number which determines whether or not a chronic-infection can be established without humoral immunity and the humoral immune response activation number which determines whether or not a chronic-infection can be established with humoral immunity. By constructing suitable Lyapunov functions we have proven the global asymptotic stability of all equilibria of the models. For the third model, we have established a set of conditions on the threshold parameters and on the general functions which are sufficient for the global stability of the equilibria of the model. We have performed some numerical simulations for the third model with specific forms of the incidence and neutralization rates and have shown that the numerical results are consistent with the theoretical results.

In order to investigate the effects of chitosan on the normal and cyclophosphamide (CY)-suppressed primary humoral immune response in mice, chitosan was orally administered alone (single dose of 62.5, 250 mg/kg) or with CY (20 mg/kg, i.p.) to female ICR mice on the 2nd day before or after immunization with SRBC-antigen. When chitosan alone was administered before antigenic challenge, splenic IgM plaque forming cells (PFC) and splenic cellularity were slightly increased and serum IgM was not changed when compared with control group. However, chitosan significantly enhanced PFC, serum IgM and splenic cellularity when administered after antigenic challenge. The PFC numbers, serum IgM and splenic cellularity were significantly decreased by the treatment of CY, whereas those values were slightly increased by the concomitant treament of CY and chitosan when compared with CY alone-administration. These results indicate that chitosan is able to increase normal humoral immunity (HI) and to slightly inhibit the suppressive effects of CY on HI.

The immunosuppressive activity of the Methanol extract of bark of Madhuca longifolia (Koenig) consisting of a mixture of saponins, flavonoids, tannins, steroids, phenol and glycosides was studied on the immune responses in mice. Methanol extract of Madhuca longifolia (MLL) was administered orally at doses of 50, 100 and 150 mg/kg/day to healthy mice divided into four groups consisting of six animals each. The assessment of immunomodulatory activity was carried out by testing the humoral (antibody titre) and cellular (foot pad swelling) immune responses to the antigenic challenge by sheep RBCs. Furthermore, the effect on hematological parameters as well as relative organ weight was determined. On oral administration MML showed a significant decrease delayed type hypersensitivity (DTH) response whereas the humoral response to sheep RBCs was unaffected. Thus MLL significantly suppressed the cellular immunity by decreasing the footpad thickness response to sheep RBCs in sensitized mice. With a dose of 100 and 150 mg/kg/day the DTH response was $7.66{\pm}2.75$ and $6.41{\pm}1.21$ respectively in comparison to corresponding value of $14.50{\pm}2.38$ for untreated control group. These differences in DTH response were statistically significant (P < 0.05). The study demonstrates that MLL shows preferential suppression of the components of cell-mediated immunity and shows no effect on the humoral immunity.
