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.

This study was performed to observe the therapeutic effects of interferon-gamma(IFN-gamma) and gamma-globulin(gamma-globulin) in experimental Pneumocystis carinii pneumonia of immune suppressed mice. After 9 weeks, trimethoprim-sulfamethoxazole(TMP-SMZ; 10-50 mg/mouse/day), mouse IFN-gamma(5 x 10(4) units/mouse/day) and mouse gamma-globulin(20 mg/mouse/day) were administered to the mice for 3 weeks by the experimental group. The therapeutic efficacy was evaluated by body weights, histopathologic and electron microscopic findings of the lungs, and number of P. carinii cysts by Gomori's methenamine silver stain. Body weights of the mice were significantly increased in the group of combination therapy of TMP-SMZ with IFN-gamma or gamma-globulin, and in the group of TMP-SMZ treatment (p < 0.05), however, little effect was found in the group of gamma-globulin alone. Histopathologic findings of P. carinii pneumonia were much improved in the group of combination therapy of TMP-SMZ with IFN-gamma. Treatment with either TMP-SMZ or IFN-gamma significantly reduced the number of cysts in the P. carinii pneumonia, but gamma-globulin alone was ineffective. In electron microscopic findings of P. carinii pneumonia, the number of trophozoites and cysts were reduced by treatment with either TMP-SMZ or IFN-gamma, and most of the cysts were empty or containing one or two intracystic bodies. The present results suggested, that combination therapy of TMP-SMZ with IFN-gamma had synergistic effects in treatment of P. carinii pneumonia in experimental mice.

Apgar score is most widely used evaluating indicator of newborn health, but it is very subjective. Umbilical cord blood gas analysis is more objective and effective than Apgar score in evaluation of newborn status. Cord blood gas was changed slightly by processing of time after fetal birth. This study was undertaken to observe objectiveness and effectiveness of umbilical arterial blood gas analysis and effects of time interval of cord clamping to newborn health with 122 pregnant women and their babies. We observed following results: 1. There were poor correlation between Apgar score and umbilical cord arterial blood analysis in evaluating of newborn health (P>0.05). 2. There was no clinical significance of Apgar score or umbilical arterial blood gas analysis as single indicator in evaluating of newborn health (P>0.05). 3. Gas analysis and pH of umbilical arterial blood was more helpful in evaluating of newborn health than Apgar score. 4. There were no significant effects of time interval of umbilical cord clamping to newborn health. 5. If there were no indications of early umbilical cord clamping, cord blood sampling at immediately after birth without cord clamping was more effective to evaluate newborn status.

We report a case of epidermolysis bullosa acquisita in a 53 year-old woman who had. extreme skin fragility, trauma induced blisters and erosions usually localized to extensor site of the skin surface, and healing with scars and milia for several years. Histologic findings of perilesional skin showed normal epidermis, subepid malblister and spirsely infiltration of inflammatory cells. Direct immuncofluorescence showed depositiori of IgCi and C3 in a linear pattern along the epidermal basement, membrane in the per ilesional skin. In indirect immuriofluorescence, using 1.0M sodium chloride separated nor mal human skin as the sntbstrate, antitodies(IgG at a titer of 1:40) were bound to dermal site of the separation, indicating that the patient serum yields the reaction in or below the lamiria densa. Electronmicroscopic findings showed the roof of the blister was located. below the basal lamiria.

Meigs' syndrome consists of an ovarian fibroma, or fibroma-like benign tumor, associated with fluid in both abdomen and chest. Characteristically, the ascites and hydrothorax disappeared and do not recurred following removal of the ovarian tumor. The authors presented a case of Meigs' syndrome that was cured by surgical removal of ovarian tumor and resulted in normal pregnancy outcome in 27-year-old pregnant woman with a brief review of literatures.

From September 1983 to June 1988, the authors could experience 104 cases of meniscal injury from 99 patients by arthroscopic examination. The results of this study may be summarized as follows : 1. There were noticed 35 cases of medial meniscus tear, 35 cases of lateral discoid meniscus tear, 12 cases of intact lat discoid meniscus, 1 case of medial discoid meniscus and 3 cases of lateral meniscal cyst. 2. Most common type of meniscal tear was bucket handle type (35 cases, 34.6%). 3. Most common site of rupture was posterior horn of medial meniscus. 4. Post operative results appeared related with the type of meniscus rupture and combined pathology of knee jont. Bucket handle type rupture was of good prognosis and meniscus lesions with chondromalacia was of poor prognosis.

9.A Case of Suburethral Leiomyoma of the Vagina.
Korean Journal of Obstetrics and Gynecology 2004;47(9):1805-1808
Vaginal leiomyoma is rare. They usually arise from the anterior vaginal wall and may be confused with a variety of vaginal tumors. Correct preoperative diagnosis is difficult. We experienced leiomyoma of suburethral area. We report this case with a brief review of literature.
