Human chorionic gonadotropin(hCG) and intravenous immunoglobulin(IVIG) treatment were attempted as a novel therapeutic approach for unexplained recurrent spontaneous abortion(RSA). Forty-four and 3 women with a history of RSA were treated with hCG and IVIG, respectively, during pregnancy. Of these patients, serum blocking factor assay was performed before and after each treatment, in 15 patients; 12 cases with hCG and 3 cases with IVIG. The results were as follows: 1. Of 44 women who receive hCG during pregnancy, 24 delivered healthy infants at term, 10 patients suffered repeat abortion, and 10 women are still pregnant under 28 weeks. Over all success rate of hCG treatment was 70.6% (24/34). Although there is no statistical significance, absolute serm blocking level was decreased after treatment(N=12). 2. Of 3 women who receive IVIG during pregnancy, all 3 women are still pregnant under 28 weeks. Serum blocking level was increased after treatment, however, this increment was not statistically significant. Although no conclusion could be extracted from the patients who received IVIG, the therapeutic effect of hCG is comparable to that of the other therapeutic regimens, such as allogeneic leukocytes. It was postulated that actual etiology of unknown RSA would be classified as hormonal origin although combined etiologies are common in Korean women.

C-type lectins are crucial for pathogen recognition, innate immunity, and cell-cell interactions. In this study, a C-type lectin gene was cloned from the rock bream. The full-length RbCTL cDNA was 729 bp with a 429 bp ORF encoding a 164-residue protein. The deduced amino acid sequence of RbCTL had all of the conserved features crucial for its fundamental structure, including the four cysteine residues involved in sulfide bridge formation and potential $Ca^2+$/carbohydrate-binding sites. RbCTL contains a signal peptide one single carbohydrate recognition domain. It showed 29.4% similarity to the C-type lectin of rainbow trout. RbCTL mRNA was predominately expressed in gill and head-kidney tissue and expressed less in peripheral blood leukocytes, trunk-kidney, spleen, liver, intestine and muscle. Expression of RbCTL was differentially upregulated in rock bream stimulated with LPS, Con A/PMA and poly I:C.

Histiocytosis X is the abnormal proliferation of histiocytes and usually a massive aggregation of eosinophilic leukocytes. The clinical features and prognosises of subclasses of histiocytosis X depend on the severity and extent of the organ involvement. The subclasses include Letterer-Siwe disease(Acute disseminated histiocytosis X), eosinophilic granuloma, Hand-Schuller-Christian disease. Letterer-Siwe disease(acute, subacute form) refers to the form of disease that is most often fatal because of the widespread skeletal, extraskeletal lesion ; this usually affects infants and children less than 3 years of age. Eosinophilic granuloma(histiocytosis X, localized) refers to a chronic form of disease with skeletal lesion ; It usually affects children and young adult. Hand-Schuller-Christian disease(chronic form) refers to a chronic form of disease with skeletal, extraskeletal lesions. It usually affects children over the age of 3 years. In our hospital, 8 year old female patient visited complaining of hard swelling of mandibule body, left side and 6 year old female patient visited complaining of painful swelling of mandibular angle, right side. We diagnosed eosinophilic granuloma and curetted the lesiones and refered to Dept. pediatrics for chemotherapy. We present 2 cases to you with literatures.

CMTM/CKLFSF is a novel family of proteins linking chemokines and TM4SF. In humans, these proteins are encoded by nine genes, CKLF and CMTM1-8/CKLFSF1-8. Here we report the characteristics and expression profile of CMTM3/CKLFSF3. Human CMTM3/CKLFSF3 has a high sequence identity among various species and similar characteristics as its mouse and rat homologues. Established by results both of RT-PCR and Quantitative Real-time PCR, the gene is highly transcribed in testis, leukocytes and spleen. For further verification, we generated a polyclonal antibody against human CMTM3/CKLFSF3 and found that the protein is highly expressed in the testis and some cells of PBMCs. Therefore, CMTM3/CKLFSF3 is an evolutionarily conserved gene that may have important roles in the male reproductive system and immune system. Further studies are necessary to validate its functions in the two systems.

A new lectin, named TRA, was purified from Trichosanthes kirilowii root by acid-treated Sepharose 6B, Mono-Q, and TSK-gel 3000SW column sequential chromatography. The lectin appeared homogeneous by native gel electrophoresis at pH 4.3 and gave two protein bands of Mr=31 and 28 kDa by SDS-PAGE. The N-terminal amino acid sequences of the polypeptides of TRA have not been reported in amino acid sequences of the lectins. TRA lectin formed a precipitate with asialofetuin, neuraminidase-treated fetuin. A sugar inhibition assay indicated that N-acetyl-D-galactosamine, among the monosaccharides tested, was the most potent inhibitor of TRA-induced hemagglutination. Asialofetuin showed a 260-times stronger inhibitory activity than N-acetyl-D-galactosamine. TRA lectin also showed agglutination with normal leukocytes and lymphoma cells, but not with premature hemopoietic cells. These results suggest that TRA is a novel plant lectin.

The integral relationship between the occurrence of lymphocyte nuclear pockets (LNPs) and BLV-infection was examined in Holstein-Friesian dairy cattle in Korea. Transmission electron microscope (TEM) was used to detect LNP in peripheral blood lymphocytes. Morphologically, the membranes of LNP were composed of two layers of double nuclear membrane. The full thickness of LNP membranes including inner and outer nuclear membrane was 60 to 70 nm. LNP prevalence was different according to the bovine leukemia virus (BLV) infection status; in BLV-seropositive cattle, LNP prevalence was 48.4% and in BLV-seronegative cattle prevalence was 5.9%. Moreover, even in seropositive animals, leukemic group was the highest at 70% positive among the groups, followed by suspect group (42.4%) and aleukemic group (23.1%). Consequently, the numbers of LNP were increased in proportion to increase of the numbers of leukocytes among BLV-seropositive cattle. The numbers of LNP per lymphocyte were increased in BLVseropositive cattle compared with seronegative cattle. The mean numbers of LNP per 100-lymphocytes were 0.35, 0.77, 1.64 and 4.7 in BLV-seronegative, BLV-seropositive aleukemic, suspect and leukemic groups, respectively. Thus, it is reasonable that LNP test can be used as the one of the diagnostic criteria of BLV infection.

Objectives: To experimentally assess the anti-depressant effects of Gammakdaejo-tang Complex Extracts (GMDJ-Tang) in rats. Methods: Twenty Wistar Hannover (160~170 g) stressed rats were treated with different concentrations of GMDJ-Tang extracts i.e., 0, 62.5 mg/kg, 125 mg/kg, and 250 mg/kg. Chronic mild stress was induced by food deprivation, empty bottles, forced swimming, flickered light, tilt cages, shaking cages, high density breeding, water deprivation, and by soaking the litter cover according to fixed schedule. Blood and brain tissue samples were collected for biochemical analysis. Tests included serotonin and ELISA assays. Results: GMDJ-tang increased the weight of treated rats as well as levels of serotonin, BDNF and TrkB; however, the differences were not significant. In contrast, the extracts significantly decreased blood glucose in stressed rats. GMDJ-tang extracts did not significantly impact Serum AST, ALT, leukocytes, erythrocytes and thrombocytes when comparing treatment groups to control rats. Likewise, hemoglobin, hematocrit and PLT increased in treatment groups following treatment with GMDJ-tang, but this change was without significance. Conclusions: These results suggest that GMDJ-tang can alleviate chronic mild stress in rats, possibly through anti-depressant activity.

The genetic basis of hypertension is complex, and has been considered to be associated with the dopamine D2 receptor gene (DD2R). Because association studies using the candidate gene approach may provide important clues regarding the pathogenesis of hypertension and establish basis for further study, we performed the association study on the relationship between genetic polymorphisms in the DD2R gene and hypertension in Koreans. Eighty nine patients with hypertension and 86 age-matched subjects with normal blood pressure were enrolled. Genomic DNA was extracted from peripheral blood leukocytes. PCR-RFLP analysis was performed to detect the three polymorphic Taq I sites in the DD2R gene. There were no significant differences in genotype, allele and haplotype distributions of any polymorphisms in the DD2R gene between two groups, respectively (P>0.05), although significant linkage disequilibriums among these polymorphic sites were detected by pair-wise analysis (P<0.05). Therefore, our negative result suggest that the three Taq I RFLPs in the DD2R gene were not significantly associated with hypertension in Koreans.

We described a rapid, sensitive and reproducible real-time PCR assay for detection and quantitation of canine parvovirus type 2 in the feces of dogs with parvovirus infection. The method was demonstrated to be highly specific and sensitive, allowing a precise canine parvovirus type-2 quantitation over range of eight orders of magnitude from $10^2\;to\;10^9$ copies of standard DNA. Then, fecal samples from parvovirus infected dogs were analyzed by conventional PCR and real-time PCR. Real-time PCR is more sensitive than conventional PCR, allowing to detect low viral titers of CPV-2 in infected dogs. By real-time PCR, a wide range of parvovirus particles was found in the samples from $1.45\times10^6\;to\;9.45\times10^8$ copies/0.01g of feces. However, when dogs are in infection of parvovirus, it is difficult to prove that the numbers of peripheral blood leukocytes are correlated with those of fecal shedding virus.

Enterotoxemia caused by Clostridium perfringens(Cl. perfringens)has occurred sporadically with devastating effect in Korean cattle. The disease is confirmed by detecting bacterial toxin the interstinal contents. however diagnosis has been challenging since the toxin is short lived and it must be demonstrated within one hour following death. The purpose of this paper is to provide additional clinicall and pathological information derived from observation of cattle administered with Cl. perfringens type A and/or its toxins isolated from natural case. Clinically cattle died suddenly in lateral recumbency with dyspnea tachycardia and muscle tremor without increased rectal temperature. hematology showed leukopenia with absolute decrease of all leukocytes. Blood glucose AST and ALT were increased. Grossly lungs were hyperemic haemorrhagic and edematous. Small intestine especially ileum was hyperemic and hemorrhagic with diffuse areas of necrosis. This study demonstrated that death without increased rectal temperature combined with leukopenia increased serum glucose pulmonary haemorrhage and edema plus necrotizing ileitis are important features associated with enterotoxemia due to Cl. perfringens type.
