Alloimmunization to red blood cell (RBC) antigens may cause a delayed hemolytic transfusion reactions (DHTR) and a delayed serologic transfusion reactions (DSTR). In the present study, the frequency of alloimmunization and its clinical significance were evaluated. Also, transfusions were correlated with antibody formation. Alloimmunization rate was 0.63%. Alloimmunization rate in multiple transfused patients was 24.5%. The most common clinically significant alloantibodies of alloimmunized patients were found to be Rh antibodies (52.6%). Nine patients out of 38 (23.7%) became undetectable after the first detection. To be positive at antibody screening test after RBC transfusion was mean transfused numbers: 3.7 units, mean transfused periods: 56 days, mean transfused frequencies: 1.7 times. The results from antibody specificity and RBC transfusions were comparatively analyzed and it shows that Rh system antibodies were longer than other antibodies (P<0.05). In case of disease group, malignant diseases was longer than other diseases (P<0.05). In order to prevent the formation of RBC alloimmunization, irregular antibody screening tests were performed at propriety intervals in multiple transfused patients.

Commercial deerhorns were extracted in boiling water, the deerhorn extracts were per os introduced into rabbits, and then the effects of the extracts on the antibody productions aginst Escherichia coli antigens were investigated for 4 weeks. The experimental rabbits were divided into 4 groups ; control, only deerhorn, only antigen, and antigen plus deerhorn treated groups. The effects of the treatments were measured by counting the number of blood cells, weighing, and immunoelectrophoresis. The rabbits' body weights gained up to 185% in the deerhorn group, and the other groups gained nearly 120%. The numbers of red blood cells in the antigen plus deerhorn group increased somewhat. However, the numbers of leucocytes gradually increased after one week in the antigen group, and at 4 weeks increased up to 290%. In the antigen plus deerhorn group the numbers of leucocytes increased suddenly up to 189% at one week, but after one week the numbers recovered to normal state. Strangely in the deerhorn group the numbers decreased up to 40%. The amounts of serum globulin increased in the control after one week, but maintained about 130%. In the deerhorn group the amounts increased like the control, but after 4 weeks increased up to 175%. In the antigen group the amounts were not changed until 2 weeks, but after 3 weeks abruptly increased over 175%. In the deerhorn plus antigen group the amounts increased gradually up to 262% until 3 weeks, after 3 and 4 weeks the amounts did not increase. The amounts of serum .gamma.-globulin decreased in the control group, and in the deerhorn group and antigen group the amounts did not change until 2 weeks, but after 3 weeks abruptly increased over 175%. In the deerhorn plus antigen group the amounts increased gradually up to 262% until 3 weeks, after 3 and 4 weeks the amounts did not increase. The amounts of serum ${\gamma}-globulin$ decreased in the control group, and in the deerhorn group and antigen group the amounts did not change until 3 weeks, but after 4 week the amounts slightly increased up to 110%. However, the amounts in the deerhorn plus antigen group did not change until 2 weeks, but after 2 weeks abruptly increased up to 174%. The recognized immunoglobulins were IgG and IgM, and the enhanced immunoglobulin was IgG.

The trial was carried out on twenty-one Friesian cows at the end of eight months gestation, nine multiparous and twelve primiparous; allocated into three groups (1 control, 2 and 3 experimental). The same diet was administred to all three groups before partum (12.8 kg DM/head/day) and after partum (18.8 kg DM/head/day). The cows in groups 2 and 3 received two different daily quantities of amino-acid chelated chromium (0.6 and 1.2 mg Cr/kg DM) from 4 weeks prior to presumed parturition to 6 weeks after. The milk yield control was carried out at 15, 30, 42 and 60 days. All animals were immunised two weeks prior to the presumed parturition and two weeks after with the following antigens: ovalbumin and brucellergene. Blood samples were collected weekly to monitor humoral and cell-mediated immune responses. When analysing the results of antibody immunity (ovalbumin) in the sixth blood collection both treated groups significantly increased compared to group 1 (0.5230 and 0.4536 vs. 0.1812 OD; p<0.05). The results of the cell-mediated immune response (brucellergene) had significant differences (p<0.10) in correspondence to the third (between group 2 and control) and the fifth (between groups 3 and 2) blood collection. Significant differences in fat corrected milk were observed at 42 days between group 3 and the other two groups (31.01 vs. 26.99 and 28.66 kg/d, p<0.05) and at 60 days between group 3 and control (30.88 vs. 26.69 kg/d, p<0.05). Before partum and at partum a positive immune response was obtained with a lower dose of chromium. After partum a positive immune response, anti-OVA indicator, was obtained with the higher dose of chromium while, $\gamma$-IFN indicator, with the lower dose. A significant increase of the milk yield resulted at both 42 and 60 days with the highest level of chromium.

To elucidate structure of group "a" epitope, mouse antibodies that express idiotype monoclonal antibody and anti-idiotype monoclonal antibody against the group specific "a" determinant were purified by hydroxyapatite column. To obtain hepatitis B surface antigens (HBsAg). HBsAg positive blood was sequencially purified by ammonium sulfate precipitation, hydroxyapatite, sepharose 4B column chromatography and ultracentrifugation. The major protein (p25) and glycoprotein (gp30) of HBsAg were isolated by concanavalin-A-sepharose 4B. The ability of p25-gp30 among the HBsAg to inhibit the idiotype-anti-idiotype reaction was dependent on conformation, since reduced and alkylated p25-gp30 virtualy lost their inhibitory capacity when compared to native HBsAg. The data suggest that hepatitis B antigen is a conformational antigen critically dependent upon the disulfide bonds of p25-gp30.

적혈구 동종면역은 수혈자와 공여자간의 적혈구 항원의 차이이다. 수혈을 위해서는 혈구형과 혈청형이 일치하지 않으면 적혈구 항체 선별 검사가 필요하며 불일치의 원인을 해명하는 것이 필수적이다. 적혈구 항체 선별검사는 임상적으로 유의한 항체를 검출하고, 신속 정확하며, 신뢰할 수 있는 방법으로 수혈에 앞서 우선적으로 하는 것을 권장한다. 본 연구자들은 다빈도로 검출된 E, D, M, E+c, C+e 항체에 대한 선별검사를 보고하였다. 따라서 이러한 결과로 항-D, 항-E의 항체가 신생아 용혈성 질환, 지연형 용혈성 수혈부작용 반응의 위험요인으로 인식하고자 한다. 또한 혈액안전관리를 적용하기 위해 적합한 항체선별검사가 요구되고, 수혈 위험요인의 선별에 있어 더 나은 효율성을 제공할 것이며 향후에 각 국가에 따라 실질적인 검출빈도를 찾는 연구가 필요할 것으로 사료된다.

Sprague-Dawley (SD) rats were orally administered with NG-nitro-L-arginine methyl ester (L-NAME), which inhibits or blocks the production of nitric oxide from L-arginine in vascular endothelial cells and vessel tissue. We examined the effects of nitric oxide on some physiological changes such as blood pressure and heart rate, and confirms the apoptosis induced by the suppressed nitric oxide activity in the kidney. This study was performed to investigate correlation between the activities of nitric oxide and apoptosis by immunohistochemical changes of apoptotic control proteins with regulated chronic inhibition of nitric oxide. In the kidney from L-NAME-treated group, immunohistochemical reaction to the antigens of apoptosis inhibiting proteins such as bcl-2 and bcl-xL, exhibited a time-dependent reduction. The expression of apoptosis-inhibiting proteins such as bax and p53 increased expression in proportion to the duration of treatment. The most sensitive apoptosis regulating proteins to L-NAME were p53 in stimulation and bcl-2 in inhibition, respectively.

Blood group determination in dogs is an important factor in transfusion medicine to minimize immediate or delayed adverse reactions after red blood cells transfusion in small animal clinics. Dog erythrocyte antigen (DEA) 1 is the most important blood type due to its high degree of antigenicity causing acute transfusion adverse reactions. The aim of this study was to investigate the prevalence of DEA 1 in various dog breeds in Korea. As a result of testing 592 blood samples from more than 35 dog breeds, DEA 1 blood typing for each breed showed that 57.8% of Malteses, 63.3% of Poodles, 76.2% of Mastiff-like dogs, 72.5% of Pomeranians, 47.7% of Shih Tzus, 70.3% of mixed breeds, 60.0% of Yorkshire Terriers, and 71.4% of Beagles were DEA 1-positive. Miniature Schnauzers and Jindo breeds had a significantly high prevalence (100%) of DEA 1-positive dogs compared to that in other small breed dogs. This is the first report of immunochromatography-detected DEA 1 prevalence in various domestic dog breeds. Although additional studies need clarifying the potential blood transfusion risks in domestic breed dogs with DEA 1, the results of this study may be useful when selecting a blood donor.

Plasma protein which has been known as one of nonspecific immunostimulators was added to feedstuff to examine its effect on the enhancement of cellular immune response in porcine immune system. A total of 40 piglets, 20 male and 20 female each, were fed for 30 days with or without plasma protein. The peripheral blood were collected and analyzed for the investigation of leukocyte subpopulations and their activities by using a panel of monoclonal antibodies specific to porcine leukocyte differentiation antigens and flow cytometry. The results obtained as follows. 1. Total weight gain, daily feed intake and feed conversion rate for 10 days were significantly improved to 56%, 20% and 22% in the piglets fed plasma protein, respectively. 2. A significant increase in N (null or non T/non B) cells was also noticed. Leukocyte proportion from piglets fed plasma protein was 20.2-24.7%, otherwise that from piglets fed without plasma protein was 12.3-13.4%, respectively. 3. A significant increase in the proportion of B cells and cells expressing poCD1 was not found in piglets fed plasma protein. 4. Reaction with monoclonal antibodies specific to adhesion molecules, poCD11a, poCD11b, poCD44 and poCD45A and poCD45B, has shown that leukocyte subpopulation from piglets fed plasma protein did not significantly higher than that from piglets fed without plasma protein. 5. Total proportion of granulocytes and monocytes was about 50% in both group and the proportion after treated with Hypaque/Ficoll was 2.7% and 5.8% in each group, respectively.
