The testicular tissue, sperm cells, seminal plasma, and the male accessory sexual glands possess enough antigenic potency to induce autoantibody formation which can render the male organism temporarily or permanently sterile. There have been relatively few immunologic studies on male accessory sexual glands. The interest of the investigators has centered mainly on the possible existence of separate characteristic antigens, in the glandular tissue and in the secretions. The induction of antibodies in the heterologous sensitization procedure, and also the potential damage developed by the accessory glands themselves, were major areas of study. The cross reactions between extracts of prostate, seminal vesicles and seminal plasma were demonstrated. And it has been reported that antibodies against testicular antigens react with epididymal sperm but not with accessory glands, whereas anti-seminal plasma antibodies react with accessory glands and seminal sperm but only weakly with testicular antigens. The purpose of this study was to observe the immunopathologic effect of rabbit anti-rat seminal vesicular serum on seminal vesicular tissue of rats and the cross reaction against testes and epididymides The results were as follow; 1. The tubules of the seminal vesicle were atrophied and accompanied by destruction with degenerative changes of the epithelium and lymphocyte infiltration. 2. There were no definite histopathologic changes on testes and epididymides. 3. Rat seminal vesicular tissue showed at least four antigenic components on immunoelectrophoresis 4. The cross reactions between seminal vesicular antigen and the anti-epididymal or anti-testicular antibody were not demonstrated on immunodiffusion test.

Mugwort and ragweed pollens have been considered as important respiratory allergens in Korea. These two pollens are abundant in the air of Seoul from August through October. Many ragweed-sensitive patients have shown concurrent sensitivities to mugwort pollen. However the antigenic relationship between these two pollens has not been clarified. To observe the cross-reactivity between them, we developed polyclonal anti-mugwort and anti-ragweed antibodies by immunization on New Zealand white rabbits, and performed crossed immunoelectrophoresis(CIE) with two pollen extracts. Five precipitation lines were formed by mugwort and anti-mugwort antibody. One precipitation line was formed by ragweed and anti-ragweed antibody. There was no reaction from mugwort and anti-ragweed antibody, and from ragweed and anti-mugwort antibody. These results indicate that there is no cross-antigenicity between mugwort and ragweed pollens.

The sero-prevalence of antibodies against blue tongue virus (BTV) in 408 local breeds of sheep in Rajasthan state in India was investigated using standard agar gel immunodiffusion (AGID) test. Maximum seropositivities of 11.3% (13/115), 10.7% (13/121), 7.1% (11/155) and 5.9% (1/17) were recorded in the Chokla, Magra, Nali and Pugal breeds, respectively. Out of 107 goat serum samples, 6 (5.6%) were AGID positive. The performance of the standard AGID, counter current immuno-electrophoresis (CCIE) and the competitive enzyme-linked immunosorbent assay (cELISA) for the detection of serum antibody against BTV in indigenous breeds of sheep were compared. Out of 178 sheep serum samples tested, 17 (9.5%), 22 (12.3%) and 54 (30.3%) were positive for group-specific bluetongue antibodies by AGID, CCIE and cELISA, respectively. There was appreciable difference in the seroprevalence detected by AGID, CCIE and cELISA in clinically healthy and diseased sheep with regard to relative sensitivities and specificities of the tests with cELISA being highly sensitive and specific followed by CCIE and AGID test. It was concluded that these indigenous breeds of sheep may be a potential reservoir of BTV infection and cELISA should be routinely used for the detection of antibodies against BTV in these local breeds of sheep.

This study was performed in order to identify changes of the plasma membrane proteins in rat submandibular gland tumors induced by 7,12-dimethylbenz[a]anthracene [DMBA] and X-irradiation. Two kinds of tumor associated membrane proteins (protein A and B) were isolated with 3 M KCl extraction from rat submandibular gland tumors induced by DMBA and X-irradiation. To identify their antigenicities, immunoelectrophoresis and double immunodiffusion was carried out with various proteins extracted from liver, heart, skin and pancreas of adult rats and from embryonic liver, heart and skin. The rabbit antisera against the protein A did not cross-react with any of the proteins extracted from the above mentioned tissues, suggesting that protein A might be tumor specific antigen. However, the rabbit antisera against protein B was precipitated with proteins extracted from the liver of adult and embryonic rats. Polyacrylamide gel electrophoresis of these two proteins (A and B) showed that protein A was a dimer with molecular weights of 69,000 and 35,000 dalton, whereas protein B was a monomer with molecular weight of 50,000 dalton.

Glanzmann's thrombasthenia is a rare autosomal recessive hemorrhagic disorder characterized by prolonged bleeding time, ad deficient or absent clot retraction in the presence of normal platelet count. The major underlying abnormality in this disease is grossly defective first-phase aggregation of platelet, which are unresponsive to ADP or other platelet agonists such as epinephrine, collagen, thrombin in any concentration. This disability is caused by a decrease or absence of the platelet membrans glycoprotein IIb-IIIa complex, a member of the integrin family of adhesive receptors involved in cell-cell and cell-matrix fibronectin, and vitronectin On the development of surface labeling technique, a variety of biochemical techniques such as radioimmunoassay, crossed immunoelectrophoresis and SDS-PAGE have been used to study the structure and the function of platelet membrane glycoproteins, and to detect the platelet functional defect. But all of these techniques demand a relatively large amount of homogeneous paletelet population that requires manipulation through isolation and washing procedures before analysis. In order to eliminaste such an intricate procedure, we have applied method for analyzing platelet surface components in whole blood using monoclonal antibody and flow cytometry to recognize the absence of severe reduction of platelet membrane glycoprotien llb-llla complex. Platelet analysis by flow cytometry is a successful alternative rapid diagnostic technique for Glanzmann's thrombasthenia patients as well as well as for carriers of this disease. Fow cytometry technique provides a sensitive tool for investigating platelet functional defects caused by altered expression or deficiency of platelet surface proteins.

BACKGROUND: To interpret the serotyping data from group A streptococcal infections and their complications, serotyping data from healthy children are essential. In this study, we determined the serotypes of the strains isolated from the elementary school children located in Seoul and Chinju. METHOD: Eighty-two strains of group A streptococci isolated from Seoul and 76 strains from Chinju were serotyped with T typing, serum opacity reaction (SOR), opacity factor (OF) and M typing. T typing was undertaken by slide agglutination after trypsinization of bacteria, SOR and OF typing by microwell technique and M typing by Ouchterlony double immunodiffusion after Lancefield's extraction method. RESULTS: In Seoul T 12 (52.4%), T 3 (9.8%), T 5 (8.5%) and T 27 (8.5%) were frequently encountered. In Chinju T 12 (44.7%), T 28 (13.2%) and T 6 (7.9%) were commonly identified. While M 12 (48.8%) and M 5 (14.6%) were most common in Seoul, M 12 (26.3%), M 22 (14.5%) and M 28 (10.5%) were widely distributed in Chinju. SOR positivity was 15.9% in Seoul and 54.0% in Chinju respectively. CONCLUSIONS: The distributions of serotypes of group A streptococci between the two areas were more or less different. Serotyping of strains from healthy children may be considered as the basic data to understand the epidemiology of bona fide group A streptococcal infections and disease association of virulent strains.

We examined the incidence of anti-Ro antibodies with sera from 60 Korean patients with systemic lupus erythematosus(SLE) by double immunodiffusion. Among these 60 sera tested, 31(51.7%) showed evident immunoprecipitations against Ro antigen on the Ouchterlony plates. Several recent studies indieate that the anti-Ro antibody occurs much less frequently in Occidental lupus patients(around 30%) than in Japanese lupus patients (50%). These data may be suggestive that the racial or ethnic baekground might be an important factor determining the serological, and perhaps the clinical features of SLE.

PURPOSE: The serum immunosuppressive acidic protein (IAP) has been reported to be a useful tumor marker for renal cell carcinoma. In a previous study, the serum levels of IAP were shown to be related to the TNM stages and the nuclear grades in patients with renal cell carcinoma. The effectiveness of the IAP as a follow-up marker for renal cell carcinoma was evaluated. MATERIALS AND METHODS: In 135 patients who underwent a radical or partial nephrectomy for renal cell carcinoma, the serum concentrations of the IAP were measured by radial immunodiffusion preoperatively and postoperatively every 3 months. The changes in the serum IAP levels in the follow-up were recorded, and the change in the recurrence group was compared with that of the non-recurrence group. RESULTS: The mean age of 135 patients (male 87, female 48) was 52.2 12.3 (18-86) years. At follow-up, metastatic recurrences were observed in 8 patients an average of 18.4 months after surgery. The metastatic lesions were found in the bone in 3 patients, the liver in 2, the lung in 2 and the spleen in 1. In patients with an increased serum IAP preoperatively, the IAP levels were significantly lower 7-9 months postoperatively (p<0.05) (from 752.4 296.8microgram/ml to 465.9 88.9microgram/ml). With the metastatic recurrence, the serum IAP level was continuously higher. CONCLUSIONS: The serum IAP might be a valuable tool in following up a renal cell carcinoma for a postoperative recurrence.
