This experiment was carried out to establish the grade of adhesion formation and changes of blood following artificial injuries such as abrasion, incision and electrocautery on colon and uterine horns in rats. 36 rats (abrasion-, incision-, electrocautery-treated groups) had laparotomy and abdominal injuries, twelve rats( control group) had only laparotomy, Ten days fellowing abdominal injuries, the score of adhesion formation and changes of blood were noted 1. Electrocautery-treated group was significant evident in adhesion formation in colon(p<0.01) and electrocautery and incision-treated groups were more evident than abrasion and control group in uterine horns(p<0.01) 2. Changes of erythrocytes number and PCV were tended to decrease during 5 days after operation, but recover normal level 10 days after operation. 3. Changes of leucocytes number were showed to significantly increase in electrocautery and incision-treated groups 5 days after operation. 4. The electrocautery-treated group was showed to significantly decrease in plasma protein and increase in plasma fibrinogen concentration.

To investigate the pathogenicity and virological properties of TJ-89-2 strain of canine parvovirus(CPV -2) that was isolated from the diseased puppies in Korea, seven puppies-were inoculated intraorally with the isolate at the HA titer of 8,192. All of the puppies showed the signs of anorexia, vomiting, diarrhea and died at the 5th to 10th days post inoculation (pi). All of the fecal samples from the puppies revealed significantly high HA titers afterward the 5th days pi. Body temperature and the number of total leucocytes were slightly increased at the early stage of infection, but extremly decreased at the stage of collapse. HI titers of the sera began to increase at the 3rd to 4th days pi, reaching 512 to 1,024 at the 4th to 5th days pi.

Polysaccharide fractions were prepared from Forsythia Corea by several different extraction schedules. The fractions obtained were designated as ForCo A, ForCo B and ForCo C respectively. ForCo C was further purified through Sephadex G 200 column chromatography and obtianed two subfractions (Coreana A, Coreana B). ForCo showed marked antitumor activity against sarooma 180 and its activity was dose-dependent. Coreana A, purified from ForCo C, showed somewhat higher antitumor activity. ForCo C increased the number of circulating leucocytes and peritoneal exudate cells, but didn't show any significant effects on the phagocytic activity and total serum protein level. Chemical analysis showed that ForCo C was composed of glucose, galactose, xylose and arabinose. A close relationship between antitumor activities and polysaccharide contents waw observed. These results indicate strongly that antitumor active principle of Forsythia Corea is polysaccharide.

Streptomycin 은 아직까지 가장 동물체에 안전한 항생물질로 알려져 왔으나, BROWNLEE와 BUSHBY (1948)에 의하면 백혈구가 Streptomycin 처리에 의해 죽는다고 하였다. 본인등은 Streptomycin을 처리한 흰쥐의 백혈구수의 변화와 백혈구 지체의 운동능에 미치는 영향을 조사하였다. 치사를 이르키게하는 최저를 이내인 10mg, 5mg, 2mg. 1mg. 0,5mg을 각각 흰쥐에 주사한 후 일정한 시간내의 백혈구수의 변화를 보면 처리후 1시간에서부터 6시간 사이에 백혈구수가 급격히 감소하며 정상지인 12,000에서 최하 3,000수까지 내려간다. 감소하는 정도는 처리량의 다소에 관계없이 대개동일하게 일어나는 것이다. 감소하는 원인을 추구하고저 쥐의 미부로부터 탐혈하여 이에 Streptomycin을 직접 접촉시켜 백혈구의 운동능을 조사하였다. Streptomycin의 량에 tt례하여 백혈구의 운동속도는 저하한다. 일정량을 초과할 때는 백혈구는 단시간내에 죽는다. 처리량의 다소를 불문하고 일정한 정도로 수의 감소가 일어나는 것과는 달리 백혈구의 운동능은 량에 따라 많은 변화를 가져온다. 이것으로 보아 백혈구수의 감소와 운동능의 저하와는 특별한 관계가 없는 것으로 보며 백혈구수 감소의 원인에 대해서는 추후 실험에서 밝혀야 할 것이다.

Sex determination in genomic DNA from human blood leucocytes was performed by amplification of human Y chromosome-specific DNA sequences using PCR technique. A clear DNA fragment(154 nucleotides long) was appeared only in the male genomic DNA, but no specific band was observed in the case of female genomic DNA and negative control. To know the sensitivity of this method, the amplification reaction was performed in genomic DNA diluted to 2pg equivalent to the amonut present in the single human cell, and clear band also observed. The PCR amplification was so succesfully performed in the single leucocyte separated from human blood using micromanipulator that this techniqe is assumed to be applied to single blstomere before embryo transfer.

These studies performed to establish the diagnostic methods for the luminal adhesions to abdominal wall with radiography, ultrasonography and electromyography, and to evalute sodium carboxymethylcellulose(SCMC) for prevention of the abdominal adhesions in goats. The adhesion sites were not detected by rediography and ultrasonography at non-pneumoperitoneum, but detected after pneumoperitoneum in goats with experimentally induced ruminal abhesions to abdominal wall. Electromyography revealed only the presence of intraabdominal adhesions. In fibriongen values and total leucocytes, there were no alterations between SCMC treated and non-treated group. The average gross scores of adhesions in SCMC treated and non-treated were 0.3 and 2.7, respectively. It was concluded that radigraphy, electromyography and ultrasonography could be available for the diagnosis of the ruminal adhesions to abdominal wall and the use of SCMC was useful to prevent the intraabdominal adhesions in ruminants.

This study was undertaken to assess the effect of ginseng administration on T lymphocyte induced local xenogenic graft-versus-host(GVM) reactions which were induced with thymocyte, spleen cell and lymph node cell of ICR mice. Mice received daily 10mg of 70% alcohol ginseng extract oral1y for 100days and control mice remained untreated for the same period of time. The cells from donor mice were injected intradermally into the closely shaven abdominal skin of Sprague-Dawley rats for GVH tests. The thymocyte from control(ginseng-untreated) mice showed a negative local GVH reaction, whereas thymocyte from experimental(ginseng-treated) mice showed a positive reaction with the rate of 17.4%. When spleen cells were injected, the incidence of positive local GVH reaction was 66.7% among ginseng-treated mice, as opposed to incidence of 45.5% of positive local GVH reaction among control mice. The incidence of positive local GVH reaction of the lymph node cells when injected into a recipient was 71.4% among ginseng-treated mice as compared with that of 18.9% among control mice. The relationship between spleen cell inoculum and intensity of the local GVH reaction was assessed in ginseng-untreated mice. The intensity of GVH reaction clearly appears to be dose related. In ginseng-treated mice, a minimum of $1{\times}10^7$ spleen cell was required for production of positive local GVH reaction with almost linear relationship up to an inoculum of $5{\times}10^8$ cells. In control mice, however, a minimum of $1{\times}10^8$ spleen cells was required for positive GVH reaction. These results strongly suggest that the ginseng administration augments significantly the local xenogenic GVH reaction which was used to assess T lymphocyte function and immunocompetence of mice and in addition to this, these results appear to support previous suggestions that the local GVH reaction consitutes a qualitative test of the functional activity of T lymphocytes. These results may be the first to induce local GVH reaction, employing rats as recipient and mice as donor. This study was also desingned to investigate some of the effects of ginseng extract on lymphocyte-macrophage interactions. This was accomplished by in vitro quantification of 1) migratory inhibitory factor(MIF) synthetic capacity of splenic lymphocytes in mice previously primed with ginseng 2) MIF responsiveness of mouse peritoneal macrophages or chicken peripheral leucocytes under the presence of ginseng extract 3) migration ability of chicken peripheral leucocytes by direct stimulation of ginseng extract or ginseng saponin and 4) immunosuppressive effects of immunosuppressants such as cyclophosphamide, cyclosporin A or dexamethasone. Mice divided equally into the ginseng and the saline groups, which received intraperitoneally daily 0.2ml of ginseng absolute alcohol-extract(5mg/ml) and same amount of saline for 15 days, respectively. The cellular immune responsiveness of these mice was assayed 15 days after ginseng pretreatment. Splenic lymphocytes of mice treated with ginseng, when stimulated with sensitized specific-antigen such as sheep red blood cells or toxoplasmin, or with polyclonal activator concanavalin A, produced significantly more MIF than those of control saline group. MIF responsiveness of normal mouse macrophages was significantly augmented when assayed under the presence of ginseng extract (1mg/ml). The migratory ability of normal chicken leucocytes in the absence of MIF was significantly decreased by the stimulation of ginseng extract alone. MIF response was significantly decreased by immunosuppressants and this impaired response was not restored by ginseng pretreatment. This study was additionally performed to evaluate the effect of ginseng on the expulsion of adult Trichinella spiralis in mice. ICR mice were infected experimentally by esophageal incubation of 300 T. spiralis infective muscle larvae prepared by acid-pepsin digestion of infected mice. and received oral administration of 70% alcohol ginseng extract(10mg/mouse/day) for the indicated days plus 4 days before infection. At various times after infection, the number of adult T. spiralis worms in small intestines was determined. Interestingly, ginseng-treatment was accompanied by accelerated expulson of T. spiralis. These results led to the conclusion that Panax ginseng caused some enhancing effect on GVH reaction, macrophage migration inhibition reaction and expulsion of T. spiralis. In addition these results suggested that the mechanisms responsible for this enhancement of ginseng may be chiefly or partially due to nonspecific stimulation of cell-mediated immune response.

The effects of dietary $\beta$-glucan administration on non-specific immune parameters in common carp, Cyprinus carpio, (1.0 g and 68.7 g of body weight) and flounder, Paralichthys olivcaces (12.1 g and 54.0 g of body weight) were evaluated. All fishes were fed an experimental diet supplemented with $\beta$-glucan at $0.1\%$ per kg diet for 5 weeks. A week intermission with basal diet occurred between first 2 weeks and second 2 weeks of $\beta$-glucan administration, The changes in the numbers of peripheral neutrophils and macrophages were counted under light microscopy and serum lysozyme activity was also analysed at a week of interval during the experiment. Phagocytic activities of leucocytes from the swimm bladder of carp and the peritonium of flounder were measured 5 weeks after feeding. The oral adminisration of $\beta$-glucan induced significant reduction in mortality after an artificial challenge with $1\times10^6$ cells of Aeromonas hydrophila in larger carp and $1\times10^5$ cells of Edwardsiella tarda in larger flounder but did not in other groups. The numbers of peripheral macrophages and neutrophils, phagocytic acitivies of leucocytes, and the activity of serum lysozyme were greatly increased in the fish fed a $\beta$-glucan supplemented diet. These suggest that $\beta$-glucan administration by oral route can enhance leucocyte phagocytic activity, serum lysozymal activity, and survival rate against artificial infections depending on the infected fish size and challenged bacterial concentration.

Purpose: In order to study the therapeutic effect of TBR(Smilacis glabrae Rhizoma) aqua-acupuncture on the $HgCI_2$(mercury bichloride) intoxicated kidneys of rats. Methods: 10% TBR extract solution was aqua-punctured into the bilateral loci of Shin-su(BL23), every other day for 18 days, and the amount of leucocytes, erythrocytes, thrombocytes, hematocrit, hemoglobin, serum BUN and creatinine levels were measured and renal mercury level and histopathological findings were studied as well. The experimental groups were into nonmaI group, control group, sample I group, sample II group and sample III group. Results: 1. There were not any significant changes of leucocytes, erythrocytes and serum creatinine level in the TBR aqua-acupuncture group, saline aqua-acupuncture group and TBR aqua-acupuncture group respectively as compared with control group. 2. It showed a significant increase of hematocrit and hemoglobin level in the TBR aqua-acupuncture group on the 8th experimental day as compared with the control group. 3. It showed a significant increase of platelet in the TBR aqua-acupuncture group on the 8th experimental day, whereas significant decreases on the 18th experimental day as compared with the control group. 4. It showed a significant decrease of serum BUN level in the TBR aqua-acupuncture group on the 8th and 18th experimental day as compared with the control group. 5. It showed a significant decrease of renal mercury level in the TBR aqua-acupuncture group on compared with the control group. 6. In the histopathological findings, TBR aqua-acupuncture group showed slight atrophy of the renal tubules, mitosis and regeneration of tubular lining cells with visible nuclei, whereas the control group showed acute tubular necrosis, especially severe necrosis of tubular epithelial cells. Conclusions: Smilacis glabrae Rhizoma aqua-acupuncture on injured kidneys Induced by HgCl2 Intoxication in Rats increases hematocrit, hemoglobin and platelet level, and decreases BUN, renal mercury level. This suggests that Smilacis glabrae Rhizoma aqua-acupuncture helps to recover kidney from HgCl2 intoxication.
