  • 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.

  • These expriments were carried out to investigate existence of H-Y antibody in the rat serum immunized against H-Y antigen from rat spleen cells and effect of H-Y antiserum on development of mouse male embryos. The results obtained were summerized as follows : 1. When mouse embryos were cultured for 48∼72 hrs in the Ham's F10 containing 16% of FBS(fetal bovine serum) or RNS(rat normal serum), percentages of embryos developed from 2, 4, 8 and 16-cell embryo to morulae were 20, 27, 94 and 100%, respectively, in FBS and 8, 7, 94 and 100%, respectively, in RNS. Eight to 16-cell embryos showed no difference in development rate between FBS adn RNS. 2. When 8∼16-cell mouse embryos were cultured for 24∼48 hrs in the Ham's F10 containing FBS, RNS+GPC(guinea pig complement) and RAS(rat antiserum)+GPC, proportions of embryos developed to the expanded blastocyst stage were 100, 82.4 and 52.1∼53.6%(ave.52.9), respectively, so that it was suggested that rat antiserum suppressed development of male embryos. 3. When 8∼16-cell mouse embryos were cultured for 24∼48 hrs in the Ham's F10 containing FBS, RNS, RNS+GPC and RAS+GPC, proportions of embryos developed to the expanded blastocyst stage were 94.5, 90.9, 82.3 and 47%, respectively, and the embryos developed in the medium containing RAS+GPC seemed to be female. These results indicated that the antisera prepared through immunized against H-Y antigen from rat spleen cell, possessed H-Y antibody which supressed development of male embryos.

  • Background: Classical swine fever (CSF) is a severe infectious disease of pigs that causes significant economic losses to the swine industry. Objectives: This study developed a solid-phase blocking enzyme-linked immunosorbent assay (spbELISA) method for the specific detection of antibodies against the CSF virus (CSFV) in porcine serum samples. Methods: A spbELISA method was developed based on the recombinant E2 expressed in Escherichia coli. The specificity of this established spbELISA method was evaluated using reference serum samples positive for antibodies against other common infectious diseases. The stability and sensitivity were evaluated using an accelerated thermostability test. Results: The spbELISA successfully detected the antibody levels in swine vaccinated with the C-strain of CSFV. In addition, the detection ability of spbELISA for CSFV antibodies was compared with that of other commercial ELISA kits and validated using an indirect immunofluorescence assay. The results suggested that the spbELISA provides an alternative, stable, and rapid serological detection method suitable for the large-scale screening of CSFV serum antibodies. Conclusions: The spbELISA has practical applications in assessing the vaccination status of large pig herds.

  • Background: Mycobacterium avium subspecies paratuberculosis (MAP) causes a chronic and progressive granulomatous enteritis and economic losses in dairy cattle in subclinical stages. Subclinical infection in cattle can be detected using serum MAP antibody enzyme-linked immunosorbent assay (ELISA) and fecal polymerase chain reaction (PCR) tests. Objectives: To investigate the differences in blood parameters, according to the detection of MAP using serum antibody ELISA and fecal PCR tests. Methods: We divided 33 subclinically infected adult cattle into three groups: seronegative and fecal-positive (SNFP, n = 5), seropositive and fecal-negative (SPFN, n = 10), and seropositive and fecal-positive (SPFP, n = 18). Hematological and serum biochemical analyses were performed. Results: Although the cows were clinically healthy without any manifestations, the SNFP and SPFP groups had higher platelet counts, mean platelet volumes, plateletcrit, lactate dehydrogenase levels, lactate levels, and calcium levels but lower mean corpuscular volume concentration than the SPFN group (p < 0.017). The red blood cell count, hematocrit, monocyte count, glucose level, and calprotectin level were different according to the detection method (p < 0.05). The SNFP and SPFP groups had higher red blood cell counts, hematocrit and calprotectin levels, but lower monocyte counts and glucose levels than the SPFN group, although there were no significant differences (p > 0.017). Conclusions: The cows with fecal-positive MAP status had different blood parameters from those with fecal-negative MAP status, although they were subclinically infected. These findings provide new insights into understanding the mechanism of MAP infection in subclinically infected cattle.

  • Antibody responses in serum and cerebrospinal fluid (CSF) samples from patients with active and chronic paragonimiasis and in sera from patients on whom follow-up studies were done after praziquantel treatment were analyzed using antigens of Paragonimus westermani prepared from eggs, metacercariae, juveniles of 4-and 7-week old, adult worms and recombinant protein of 28 kDa cruzipain-like cysteine protease (rPw28CCP). The patient sera/CSFs of active and chronic paragonimiasis revealed strong antibody reactions against the crude extracts of 4-and 7-week old juveniles as well as against those from egg and adult. rPw28CCP also showed specific reaction to the sera with active paragonimiasis. After the treatment, levels of specific antibodies in the sera gradually decreased to negative range in most patients. In some cases with persisting high antibody levels, however, the reactions at 27 kDa egg Protein were sustained throughout the observation period of 34 months. The reactions at 35 and 32 kDa in adult extract and rPw28CCP disappeared rapidly after the treatment. Persistent antibody reactions even after successful treatment are provoked by continuous antigenic challenge from eggs which were not resolved by treatment.

  • Eleutherococcus senticosus is a typical oriental folk medicinal herb. It has been used clinically as a anti-rheumatic disease, anti-stress, ischemic heart disease and gastric ulcer. In the present study, we examined the adjuvant activity of the crude polysaccharides fraction from Eleutherococcus senticosus, EN-3, on the induction of humoral and cellular immune responses against bovine serum albumin (BSA) or ovalbumin (OVA). The thioglycollate-induced macrophages and silica-induced dendritic-like cells cultured with BSA and EN-3 synergistically increased the production of TNF-$\alpha$ and IL-12. When mice were subcutaneously immunized with BSA + EN-3, the antibody titer against BSA was showed significantly higher than those immunized with BSA alone. In addition, when mice were immunized with OVA + FIA + EN-3, the antibody titer was showed similar patterns with the FCA. The assay for determining subisotype of antibody revealed that EN-3 augmented OVA-specific antibody titer of IgG1 and IgG2b. The culture supernatant obtained from splenocytes of mice treated with OVA + FIA + EN-3 also showed a higher level of both OVA-specific Th1-type (IL-2, IFN-${\gamma}$ and GM-CSF) and Th2-type cytokine (IL-4, IL-6 and IL-10). In vitro analysis of T cell proliferation to OVA on 8 weeks, the splenocytes of mice treated with OVA + EN-3 showed a significantly higher proliferating activity than those treated with OVA alone. These results suggest that EN-3 may possess adjuvant activities to potentially to enhance humoral as well as cellular immune response.

  • Background: Although a skin test is the primary option for detecting allergen-specific IgE in clinics, the serum IgE immunoassay is also important because it allows for the diagnosis of allergy without any accompanying adverse effect on the patient. However, the low detection limit of IgE levels by immunoassay may restrict the use of the method in some occasions, and improving its sensitivity would thus have a significant implication in allergy-immunology clinics. Methods: In this study, we attempted to detect specific serum IgE by using immuno-polymerase chain reaction (IPCR) which combines the antigen-antibody specificity of enzyme-linked immunosorbent assays (ELISAs) with the amplification power of PCR. Results: Our results demonstrated that Blo t5-specific serum IgE can be detected by IPCR with a 100-fold higher sensitivity than ELISA, and cross-reactivity of serum IgE to other mite allergens is able to be analyzed by using only $0.3{\mu}l$ of serum sample. Use of real-time IPCR seemed to permit more convenient determination of specific serum IgE as well. Conclusion: We believe that IPCR can serve as a valuable tool in determining specific serum IgE, especially when the amount of serum sample is limited.

  • 뇌 유구낭미충증의 진단에는 혈청뿐만 아니라 뇌척수액내 특이 IgG항체가도 측정하여 혈청학적 진단의 민감도를 약 10% 높일 수 있다. 이 경우 뇌척수액내 특이 IgG항체가 그 환자의 혈청에서 혈관-뇌 장벽을 넘어 이전된 것인지 또는 두개강내 병변에 형성된 육아종에서 생성한 것인지를 결정하는 일은 뇌척수액내 특이 IgG항체가 측정의 의미를 부여하는 데에 중요하다. 이 연구는 그 기원을 찾기 위하여 실시하였다. 확진된 뇌 유구낭미충증 환자 82례와 기타 신경계질환 환자 및 건강대조인 45례에서 오은 혈청과 뇌척수액에서 각각 총단백질, 알부민 및 IgG 농도를 측정하였다. 그리고 Tourtellotte and Ma (1978)의 공식에 의하여 뇌척수액내 IgG농도를 여출(濾出, transudation; 혈관-뇌장벽이 정상인 상태에서 생리적으로 뇌척수액으로 이전된 것), 삼출(渗出, exudation; 혈관-뇌장벽이 파괴된 상태에서 병적으로 이전된 것) 및 두개강내 생사 등 세가지 기원으로 분리하였다. 고리고 혈청 및 뇌척수액내 특이 IgG항체가를 효소 면역측정법으로 측정하였다. 뇌척수액내 특이 Ig9G항체가와 각기원별 IgG량과의 관계를 통계학적으로 검정하였다. 그 결과를 요약하며 다음과 같다. 1. 뇌 유구낭미충증 환자 뇌척수액에는 총단백질, 알부민 및 IgG평균치가 상승되어 있었다. 각 단백질 농도는 혈청내 특이 IgG항체가와는 관계없이 뇌척수액내 IgG항체가 양성자에서 높았다. 2. 뇌 유구낭미충증 환자의 뇌척수액내 IgG량(14.0mg/dl)은 여출(4.52mg/dl), 삼출(2.94mg/dl) 및 두개강내 생산(6.88mg/dl)으로 구성되었다. 뇌척수액왜 특이 IgG항체가는 여출 및 삼출에 의한 IgG양과는 통계학적 유의성이 없는 관계이었으나 두개강내 생산량과는 유의한 관계가 있었다. 3. 제 4뇌실에 병 변이 화인된 뇌유구낭미충증 환자의 측뇌실에서 얻은 뇌척수액에는 총단백 질, 알부민 및 IgG량이 정상범위이었고 특이 IgG항체는 음성이 었다. 같은 환자의 요추천자로 얻은 뇌척수액에서는 각 단백질이 상승되어 있었고 특이 IgG항체가는 양성이었다. 4. 뇌 유구낭미충증 환자의 뇌척수액내 EgG량중 삼출에 의한 양이 증가된 예에서는 대부분 두개강내 IgG생산이 동반되고 있었다. 따라서 삼출에 의한 뇌척수액내 IgG 출현은 뇌유구낭미충증의 진행중 어느 시기에 특히 심한 것으로 추정된다. 이상의 결과에서 유구낭미충증 환자의 뇌척수액내 특이 IgG항체는 두개 강네 병변에서 생산된 것임을 알 수 있었다. 따라서 뇌척수액을 이용한 특이 IgG항체 측정은 진단에 도움이 된다고 생각된다.
