This experiment has been made to evaluate the distribution of OEP-HA titer, protease-HA titer and elastase-HA titer of antibody which are the common antigen of Pseudomonas aeruginosa in the serum of healthy mother-newborn infant-pairs, term pregnancy women and under 7 month old infants. By analysing the normal limt of these antibodies, it is expected that the result can be clinically applicable to the diagnosis, management and prevention of Pseudomonas aeruginosa infection, which shows rapid increase nowadays, 1. The Anti OEP-HA titer showed under 1:8, a very low titer, in 73% of cord sera group, but over 1:32 in 68% of mother sera group. 2. In healthy mother-newborn infant-pairs group, the anti OEP-HA titer of mothers showed 1:56, 48, much higher than that of newborn infant, 1:16.42. from which it can be concluded that their titer has no relation between the two. 3. The anti OEP-HA titers of healthy mother and term pregnancy women showed 1:56.5 and 1:53, 4, respectively, which are very similar to each ether, but in infant group, the titer showed 1:33, 51 higher than that of cord sera, 1:16.42 4. The anti protease-HA titer showed under 1:8 in 64-77.5% of total cases, which is lower than that of anti OEP-HA titer. 5. The anti elastase-HA titer showed under 1:8 in 93.75% of cord sera group and in 70.27-76.37% of infant, term perenancy women and mother group, but in infant group, the anti elastase-HA titer showed 1:16.56 higher than that of cord sera group 1:8.5.

Effects of Astragali radix extract (AG) on the humoral immunotoxic responses of zinc chloride (Zn) were studied in ICR mice. Mice were divided into 4 groups (10 mice/group), and Zn was given to the mice, 1 hr after i.p. injection with 0.5 g/kg of AG, by i.p. injection daily for 10 days at a dose of 25 mg/kg. Mice were immunized and challenged with sheep red blood cells (SRBC). Zn treatment increased the relative weight of spleen compared with those in controls, but decreased the hemagglutination (HA) titer 2-mercaptoethanol-resistant HA (MER-HA) titer and splenic plaque forming cells (PFC). AG treatment significantly increased the relative weight of spleen, HA titer and PFC compared with those in controls. Combination of Zn and AG significantly increased the relative weight of spleen compared with those in controls, but decreased the HA titer, MER-HA titer and PFC. The relative weight of spleen was significantly increased in the Zn and AG combination group than those in Zn alone treatment group. But the HA titer, MER-HA titer and PFC were slightly increased in the group of combination. These results suggest that AG might slightly restore humoral immune responses lowered by an excess of zinc.

Effects of swainsonine (SW;8${\alpha}$, ${\beta}$-indolizidine-${\alpha}$, $2{\alpha}$8-triol from Locoweed) on the humoral immune responses of lipopolysaccharide (LPS) wer studied in ICR mice. Mice were divided into 4 groups (10 mice/group), and LPS was given to each mouse 1 hr after i.p. injection with 3.7 mg/kg of swainsonine, by i.p. injection twice a week for 14 days at a dose of 2 mg/kg. Humoral immune responses were evaluated by hemagglutination (HA) titer and splenic plaque forming cells (PFC). The results of this study were summarized as follows: Mice administrated each of LPS and SW showed significant enhancement of the weight ratios of spleen to body, HA titer, 2-mercaptoethanol-resistant HA(MER-HA) titer and PFC compared with those in controls. However, the LPS plus SW treatment decreased HA titer, MER-HA titer and PFC corresponding to humoral immunity, as compared with those in the mice treated with LPS alone. These findings indicated that LPS significantly enhanced humoral immune responses, but their enhancement effects were lowered somewhat by SW.

To investigate the effects of carboxyethylgermanium sesquioxide (Ge-132) on the cyclophosphamide (CY)-induced immunotoxicity, hemagglutinin titer (HA-titer), splenic IgM plaque forming cells (PFC) and contact-delayed type hypersensitivity (CDTH) were assessed in mice. Ge-132 was orally administered alone (single dose of 300, 600, 900 mg/kg b.w.) or with CY (10 or 50 mg/kg, i.p.) to mice on the 2nd day before, simultaneously with, the 2nd day after immunization. Within Ge-132 alone-treated groups, HA-titer and PFC to SRBC were significantly and dose-dependently enhanced when compared with control group. HA-titer and PFC numbers suppressed by the treatment of CY alone were significantly restored by the concomitant treatment of CY and Ge-132. Also, Ge-132 significantly decreased DNFB-induced CDTH and inhibited the CY-enhanced CDTH. These results indicate that Ge-132 may be able to increase humoral immunity and inhibit the immunotoxicity by CY.

The immunopotenciating effects of ethanol extract, butanol fraction and petroleum ether extract of Korean Ginseng on the immunotoxicity of mitomycin C were investigated in mice. A single administration of mitomycin C induced an apparent but relatively transient reduction of spleen weight, hemagglutination titer, Arthus reaction, RFC and natural killer cell activity. Ethanol extract of Ginseng significantly restored spleen weight, HA titer, RFC and natural killer cell activity. Butanol fraction of Ginseng significantly restored HA titer, RFC and natural killer cell activity. Petroleum ether extract of Ginseng very significantly restored spleen weight, Arthus reaction, DTH, RFC and natural killer cell activity.

Encephalomyocarditis(EMC) virus was isolated from the mummified and stillborn pigs at a swine farm in Chonnam Province, experienced with EMC infection over the period Oct.~Dec. of 1989. In addition some cultural, serological properties of the isolates and experimental infections in the piglets were studied. The results obtained were as follows; 1. Two EMC virus strains with HA titers and CPE similar to EMC-ATCC were established in a baby hamster kidney (BHK)-21 cell line by inoculating homogenates of brain and heart of the 19 mummified or stillborn pigs and designated $K_3$ and $K_{11}$. 2. At the second BHK-21 cell line passage of the initial isolates CPE appeared after incubation for 16~18 hours, while at the fourth and fifth passage the highest titer of HA was recorded, titer of HA using rat and guinea pig erythrocytes. 3. One pig inoculated with the isolate $K_3$ showed dyspnea as clinical signs and died at the 10 days after inoculation at necropsy white necrotic foci were observed from the dead animal heart. 4. Although all the rest surviving pigs showed increases in antibody titer and body temperature of $40^{\circ}C$ above for the initial 2~4 days followed by the return to normal, there were no gross lesions when the animals were sacrificed at the 2 weeks after inoculation.

Experiments were performed on rats to investigate the effect of doses of capsaicin on the immune response. Olive oil and the 0.3 mg, 1.0 mg and 3.0 mg/kg administration of capsaicin in olive oil were injected intraperitoneally every day for 4 weeks. Rats were sensitized and challenged with sheep red blood cells (S-RBC). Immune responses were evaluated by organ weight, HA and HY titer, Arthus reaction, delayed type hypersensitivity (DTH) and Rosette froming cell. Following results have observed. 1) The weight of spleen and thymus were increased by doses of compared with control group, but the body weight of rats was decreased. 2) HA titer, Arthus reaction and DTH were significntly decreased by doses of capsaicin as compared with control group. 3) Rosette forming cell in spleen cells was decreased according to the increase of capsaicin doses. These results suggested that high dose of capsaicin decrease humoral and cellular immune response in rats.

Effects of zinc chloride (Zn) on the immune responses of lipopolysaccharide (LPS) were studied by using ICR mice. Mice were divided into 4 groups (10 mice/group), and Zn was given to the mice with i.p. injection at 0.3 mg/kg 5 times a week for 14 days, and 1 hr after Zn administration, LPS was given with i.p. injection at 5 mg/kg twice a week. Mice were immunized and challenged with sheep red blood cells (SRBC). Immunobiological responses were evaluated by humoral, cellular and nonspecific immunity. LPS treatment significantly increased the relative weights of spleen and thymus, hemagglutination titer (HA) and proliferation of splenocytes compared with those in controls, but significantly decreased the body weight gain. Zn treatment significantly increased proliferation of splenocytes and circulating leukocytes compared with those in controls. Combination of Zn and LPS significantly decreased the body weight gain and proliferation of splenocytes compared with those in controls. Combination of Zn and LPS significantly decreased HA and proliferation of splenocytes than in LPS alone. These findings indicate that zinc lowered the humoral immune responses of LPS.

The humoral immune response of Eicosapentanoic acid(EPA) was investigated in mice. ICR male mice were divided into 8 groups and received intraperitoneal injection of EPA(5 mg, 10 mg, 20 mg/kg) for 4 weeks. Cyclophosphamide(5 mg/kg) was administered i.p. 2 days prior to secondary immunization. Humoral immune response was evaluated by antibody titer, hypersensitivity to SRBC (Arthus), plaque forming cell(PFC) and organ weight. The ontanined results were as followings: The increased rate of body weight, the ratio of liver weight, spleen weight to body weight were decreased by all EPA administration groups as compared to normal group. HA titer, HY titer and Arthus reaction were enhanced according to the increase of EPA doses as compared to normal group. PFC was significantly enhanced by EPA 10 mg administration group. These results suggest that EPA enhances humoral immune response to SRBC in mice, indicating that EPA may block a immunoglobulin synthesis inhibition of arachidonic acid.
