1.T cell phenotype and intracellular IFN-gamma production in peritoneal exudate cells and gut intraepithelial lymphocytes during acute Toxoplasma gondii infection in mice.
The Korean Journal of Parasitology 2002;40(3):119-129
Although there are many reports on the splenic (systemic) T cell response after Toxoplasma gondii infection, little information is available regarding the local T cell responses of peritoneal exudate cells (PEC) and gut intraepithelial lymphocytes (IEL) following peroral infection with bradyzoites. Mice were infected with 40 cysts of the 76K strain of T. gondii, and then sacrificed at days 0, 1, 4, 7 and 10 postinfection (PI). The cellular composition and T cell responses of PEC and IEL were analyzed. The total number of PEC and IEL per mouse increased after infection, but the ratio of increase was higher in IEL. Lymphocytes were the major component of both PEC and IEL. The relative percentages of PEC macrophages and neutrophils/eosinophils increased significantly at day 1 and 4 PI, whereas those of IEL did not change significantly. The percentage of PEC NK1.1 and gamma delta T cells peaked at day 4 PI (p < 0.0001), and CD4 and CD8 alpha T cells increased continuously after infection. The percentages of IEL CD8 alpha and gamma delta T cells decreased slightly at first, and then increased. CD4 and NK1.1 T cells of IEL did not change significantly after infection. IFN-gamma-producing PEC NK1.1 T cells increased significantly from day 1 PI, but the other T cell subsets produced IFN-gamma abundantly thereafter. The proportion of IEL IFN-gamma-producing CD8 alpha and gamma delta T cells increased significantly after infection, while IEL NK1.1 T cells had similar IFN-gamma production patterns. Taken together, CD4 T cells were the major phenotype and the important IFN-gamma-producing T cell subsets in PEC after oral infection with T. gondii, whereas CD8 alpha T cells had these roles in IEL. These results suggest that PEC and IEL comprise different cell differentials and T cell responses, and according to infection route these factors may contribute to the different cellular immune responses.

The eye is a common target organ of the allergy, and allergic conjunctivitis is the most common of eye diseases. Clinical manifestations of allergic conjunctivitis are acute bilateral red, itchy, and watery eyes. The presence of conjuncitival eosinophilia may be consided to be a diagnostic indicator of allergic conjunctivitis. ECP is a quantifiable toxic product secreted by activated cosinc phils. VCAM-1 promotes adhesion of leukocytes to endothelium in vitro and may promote imflammation in vivo. The objective of this study is to measure eosinophil count, ECP and sVCAM-1 levels of tears and sera in patients with acute allergic conjunctivitis and normal subjects and to assess the correlation of these mediators with the severity of the disease and the clinical usefulness. Seventeen subjects were selected on the basis of clinical manifestations, history, skin prick test, total IgE. A microcapillary tube was used to collect the tears from the inner canthus, conjunctival epithelia were obtained for eosinophil count by scraping the upper tarsal conjunctiva. The level of ECP was measured by CAP system (Kabi-Pharmacia, Sweden), sVCAM-1 was measured by ELISA (R&D, USA). Serum IgE and eosinophil count were in creased in 10 patients, allergic skin prick test were positive in 11 subjects (D.p: 9, D.f: 8), eosinophilia in conjunctival epithelium were present in 11 subjects (4 patients: > 3/HPF, 7 patients: 1-3/HPF). ECP in tears were increased in patients significantly (12.0+8.0 vs 3.9+3.8 ng/ml, p=0.01), but not in serum (52.5+43.1 vs 28.3+25.9 ng/ml). There is no significant correlation between eosinophil count and ECP in serum and tears (p>0.05, r-=0.19). Serum sVCA-M-1 level is significant different between patients and controls (1916.5+756.0 vs 1147.2+146.1 micro gram/ml, p=0.01), sVCAM-1 is significantly correlated to eosinophil count (p=0.01, r=0.56) and ECP (p<0.05, r=0.65). In conclusion, eosinophil and ECP in tears may be very important role in allergic conjunctivitis and are useful indicators of the disease. The elevation of sVCAM-1 in serum may be interpreted simply as marker of the presence of non-specific inflammation.

The most commonly used graft source for anterior cruciate ligament reconstruction is the autogenous bone- patellar tendon-bone graft unit. Despite a good success record, intraoperative technical errors and postoperative complications have been known. Author analyzed intraoperative technical errors and postoperative complications, in 44 patients who were treated at the department of orthopaedic surgery, chosun university hospital from Jan. 1994 to Jun. 1996. The most common intraoperative technical errors was screw graft divergency in 5 cases. Other intraoperative technical errors were too anteriorly location of femoral tunnel in 1 case, too anteriorly location of tibial k femora) tunne.l both in 1 case, graft tunnel mismatching in 1 case, graft pullout in 1 case and partial destruction of posterior cortex of femoral tunnel in 1 case, fracture of the bone plug in 1 case. The most common postoperative complication was patellar tendinitis in 20 cases (45.5%). Other postoperative complications were anterior knee pain in 14 case. (31.8%), patellar crepitation in 12 cases (27.3%), quadriceps atrophy in 9 cases (20.5%), arthrofibrosis in 3 cases and graft failure in 2 cases. Author concluded the causes of intraoperative complications were technical errors, and anteriorly location of graft tunnel is most influenced factor to final fuctional results. To eliminate the postoperative complications, intraoperative technical errors should be avoided and also accelerated rehabilitation should be done.

Strongylodiasis is universal in distribution but is most abundant in countries with a tropical climate. Although infestation by Strongyloides stercoralis is usually limited to the intestines, dessemination of this helminth in debilitated host can be lead to death with various clinical disorders. characterized by profound malabsorption, diarrhea, electrolyte imbalance, gram negative or opportunistic fungal sepsis, coma and death. Cell-mediated immunity contributing significantly to the control of helminthic infections, may be suppressed by carcinoma, immunosuppressive chemotherapy and use of corticosteroids. Diagnosis of Strongyloidiasis is achieved by an examination of samples of feces, duodenal aspirates and sputum of patients for Strongyloides stercoralis. Treatment of strongyloidiasis is twofold : correction of the immunosuppressive state by withdrawal of immunosuppressive drug, if possible, and vigorous treatment with thiabendazole. Testing for strongyloidiasis is especially recommanded before treating a patients should be monitored for infection by Strongyloides stercoralis and other opportunistic infection. We are reporting a case patient with Strongyloides stercoralis hyperinfection and pulmonary tuberculosis who had been. used corticosteroid for persisting polyarthritis.

Erythropoietic protoporphyria, sometimes also called erythrohepitic protoporphyria or simple protoporphyria, is a heritable detect of heme synthesis in which the last enzyme of the heme synthetic pathway, ferrochelatase(or heme synthetase), is functioning subopt,imally. A 23-year-old male has experi nced erythema and edema on the fae and hands during or immediately after sun exposure, since 3 years of age. The skin lesions have been accompanied by severe itching, a buring sensation and pain. Severe episodes were followed hy head iche and vomiting. We have seen a case of erythropoietic protoporphyria presenting clinically and histo athologically, wit.h a skin lesion on the sun exposured area, and free erthrocyte protoporphyrin serologically.

Synovial sarcoma is a distinct and generally recognized soft tissue tumor that it’s origin still raises controversy. The synovial origin of synovial sarcoma has not been determined despite the accepted terminology implying synovium as stem cell. Three cases of primary synovial sarcoma (2 fibrous monophasic, 1 biphasic type) were studied with a panel of antibodies against different types of cytokeratin and other markers (EMA, CEA, vimentin, S-100 protein, lysozyme, 1-antichymotrypsin). Spindle shaped-cell in monophasic synovial sarcoma showed reactivity for CK7 and pancytokeratin. Epithelial cells lining of glands in biphasic synovial sarcoma reactive for CK7, pancytokeratin, EMA, and focally CEA but spindle cells only positive for vimentin. By electron microscopy, fibrous monophasic synovial sarcoma showed pseudogland formation with intercellular junctions of paired subplasmalemmal destiny and discontinuous basal lamina. These results indicate that synovial sarcoma showes epithelial differentiation. We believe that synovial sarcoma arises in pluripotential connective tissue cells that is able to be differentiated into both mesenchymal and epithelial components. So, synovial sarcoma have been considered carcinosarcoma of soft tissues depending on the type of differentiation.

The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed by Stoll's egg-counting technique, and praziquantel was administered to positive cases. The egg-positive rates for Clonorchis sinensis and Metagonimus species were 9.3% and 5.5%, respectively, and the double infection rate was 3.5%. The numbers of eggs per gram (EPG) of feces of C. sinensis and Metagonimus sp. were 918 +/-1.463 and 711+/-947, respectively. The egg-positive rates for C. sinensis and Metagonimus sp. in the riverside area were 14.2% and 8.4%, respectively, which were significantly higher than those of the inland area (3.2% and 1.7%, respectively). The egg-positive rates of C. sinensis and Metagonimus sp. in males (16.7% and 10.0%) were significantly higher than those of females (3.5% and 1.8%). However, there were no significant differences of EPG values between localities and sexes. The prevalence of clonorchiasis and metagonimiasis in this survey was significantly lower than that in the previous reports. However, there is still a high prevalence of infection with C. sinensis and Metagonimus sp. in this region, especially in the riverside area.

In Korea, all domestic made test systems for detecting antibodies in HIV-1 contain the antigens from human immunodeficiency type 1 (HIV-1) subtype B. However, because HIV-1 subtype O is significantly different in amino acid sequences from all other subtypes of HIV-1, there has been a need for developing a test for detecting antibodies in subtype O. For this purpose, the entire nucleotide sequence corresponding to the extracellular domain of the transmembrane glycoprotein of HIV-1 subtype O was synthesized with consideration of Escherichia coli cordon usage. Various regions of the extracellular domain were cloned into E. coli expression vectors and tested for levels of protein production. The nucleotide sequence, named ECTM, that can encode a 129 amino acid-long peptide, was found to be expressed at a high level in E. coli. The protein of approximately 17 kDa specifically reacted with sera from individuals infected with HIV-1 subtype O. The ECTM protein was purified to near homogeneity by the CM-T gel chromatography, using concentrated, denatured inclusion bodies. In Western blot analysis, the purified viral antigen reacted with sera from individuals infected with subtype O more efficiently than subtype B. The enzyme linked immunoabsorbent assay (ELISA) system was developed using the subtype O viral protein and compared with the commercially available kit lacking the antigens from subtype O. The ELISA kit containing the subtype O antigen ECTM alone efficiently reacted with sera from individuals infected with subtype O. The subtype O antigen-containing kit produced a positive absorbence even when sera were diluted 512-fold, suggesting a high sensitivity. The commercially available kit also reacted with subtype O sera, but produced a negative result at a dilution of 8-fold. Our results suggest that the currently available kit may not be able to efficiently detect subtype O sera and that the viral protein developed in this study may be added to the current system to maximize the detection of sera from individuals infected with subtype O.

The Journal of Advanced Prosthodontics 2014;6(5):325-332
PURPOSE: The aim of this review was to analyze the evaluation criteria on mandibular implant overdentures through a systematic review and suggest standardized evaluation criteria. MATERIALS AND METHODS: A systematic literature search was conducted by PubMed search strategy and hand-searching of relevant journals from included studies considering inclusion and exclusion criteria. Randomized clinical trials (RCT) and clinical trial studies comparing attachment systems on mandibular implant overdentures until December, 2011 were selected. Twenty nine studies were finally selected and the data about evaluation methods were collected. RESULTS: Evaluation criteria could be classified into 4 groups (implant survival, peri-implant tissue evaluation, prosthetic evaluation, and patient satisfaction). Among 29 studies, 21 studies presented implant survival rate, while any studies reporting implant failure did not present cumulative implant survival rate. Seventeen studies evaluating peri-implant tissue status presented following items as evaluation criteria; marginal bone level (14), plaque Index (13), probing depth (8), bleeding index (8), attachment gingiva level (8), gingival index (6), amount of keratinized gingiva (1). Eighteen studies evaluating prosthetic maintenance and complication also presented following items as evaluation criteria; loose matrix (17), female detachment (15), denture fracture (15), denture relining (14), abutment fracture (14), abutment screw loosening (11), and occlusal adjustment (9). Atypical questionnaire (9), Visual analog scales (VAS) (4), and Oral Health Impact Profile (OHIP) (1) were used as the format of criteria to evaluate patients satisfaction in 14 studies. CONCLUSION: For evaluation of implant overdenture, it is necessary to include cumulative survival rate for implant evaluation. It is suggested that peri-implant tissue evaluation criteria include marginal bone level, plaque index, bleeding index, probing depth, and attached gingiva level. It is also suggested that prosthetic evaluation criteria include loose matrix, female detachment, denture fracture, denture relining, abutment fracture, abutment screw loosening, and occlusal adjustment. Finally standardized criteria like OHIP-EDENT or VAS are required for patient satisfaction.
