N/A Objectives: To evaluate the clinical utility of recently developed biochemical markers of bone turnover to monitor the response of osteoporotic patients to antiresorptive therapy, we compared the results of two advanced assays for markars of bone resorption and two of bone formation. Subjects and Methods: The rate of bone turnover in 37 women (mean±SD age, 58.2±4.5yr) with low boe mass and all postmenopausal women (mean±SD yr PMP, 8.3±5.2) was compared to that in 16 Premenopausal women(mean+SD age, 40.2±5.3yr) randomly selected from out-patient in our hospital and all have a normal spine bone mineral density(BMD). Perodically during the 12-month study,the level of several markers of bone turnover wen, measured. Serum osteocalcin, bone specific alkaline phosphatase mesured by RIA were used to assess bone formation. To assess bone resorption, we measured urinary excretion of Dedxypyridinoline, type l collagen cross-linked N- telopeptide, Result: All bone formation markers and all bone resorption marker were significantly increased in PMP Osteoporotic women. Under treatment with alendronate, resorption markers decreased earlier than marker of bone formation, Conclusion: This study, using biochemical markers of bone turnover, demonstrates that bone turnover is increased in PMP osteoporotic women. Alendronate treatment decreased bone turnover to the normal premenopausal range, with a steady state level reached after 1 month of therapy with 10mg for resorption markers and after 3-6 months of therapy for markers of bone formation.

"Our purpose was to investigate the effects of hormone replacement therapy on the reactivity of monocyte in whole blood, mesured by tissue factor activity. Thirty-eight women were randomized into oral combind homone replacement therapy and underwent blood sampling before and 3 and 12 months of treament,The tissue factor activity in monocytes was measured both in unstimulated whole blood and after a weak lipopolisaccaide stimulation. After 12months of hormone replacement therapy there were significant reduction of tissue factor activity in both unstimulated and lipopolisaccaride stimulated monocyte (p<0.001). Twelve months of hormone replacement therapy reduces cellular activation of blood monocytes; these changes may account for some of the beneficial effects in reducing the risk of cardiovascular disease.

Objective: To evaluate the effect of serum obtained before and after treatment for endometriosis on in vitro fertilization and development of two cell mouse embryo. Design: Pretreatment and posttreatment comparoson of fertilization of mouse oocyte and embryo development in serum supplement from patients with endometriosis; result were compared using Stuent T-test analysis. Method: Infertility Clinic, Department of Obstetrics and Gynecology, Collage of Medicine, Won kwang university, Korea. Patients was chosed eleven consecutive women with endometriosis. Interventions was all patient underwent laparoscopic or conservative surgery. This was followed by a 6-month course of burserelin acetate $900{\mu}g/d$. Main outcome was measured total number of fertilization and embryo that was fertilization after 24 hours and reached blastocyst stage after 72 hours of incubation were compared before and after treatment. Result: Before treatment, 47% of the oocyte were fertilized and 31% of the embryo reached blastocyst stage. After treatment, Significantly more fertilized and Significantly more embryo developed to blastocyst on the stage I and II of endometriosis. Conclusion: The fertilization and embryo toxicity of serum samples from patients with endometriosis is lost after treatment.

The cell cycle is composed of a series of steps which can be negatively or positively regulated by various factors. p53 gene aberrations are common in human malignancies, and recent studies suggest that in cervical carcinoma p53 function is inactivated either by complex formation with human papilloma virus (HPV) E6 product or by gene mutation. To study the expression of p53 gene in the cervical cancer and cervical intraepithebal neoplasia, immunohistochemistry for the p53 protein was done in the 47 cases of squamous cell carcinoma, 6 cases of adenocarcinoma and 32 cases of cervical intraepithelial neoplasia. 1. The p53 protein was detected in the 31% of cervical intraepithelial neoplasia (10/32 cases). 2. The p53 protein was detected in the 55% of invasive cervical cancer (29/53 cases). 3. By the histologic type of cervical cancer, the p53 protein was detected in the 57% of squamous cell carcinoma (27/47 cases) and 33% of(2/6 cases) adenocarcinoma. The p53 protein wes more frequently detected in the squamous cell carcinoma than in the adenocarcinoma. 4. By the staging in cervical cancer, the p53 protein was detected in the 31% of stage 0, 50% of Stage Ia, 50% of stage I b, 75% of IIa and 50% of stage IIb.

안티몬이 첨가된 산화주석 얇은막 전극의 반도체적 성질을 조사하고 이산화황의 산화반응에 대한 이 전극의 전기화학적 촉매작용을 여러가지 조건하에서 조사하였다. $SO_2$(또는 아황산염)를 포함하는 전해질 용액의 pH가 증가함에 따라 점차로 낮은 전위에서 산화가 일어났으며 이 전극은 염기성 용액에서 $SO_3^=$의 산화에 대하여 뚜렷한 전기촉매 작용을 나타내었으며 이 전기촉매 작용은 백금이나 팔라듐 전극의 촉매작용과는 다른 특성을 보여주었다. 백금이나 팔라듐이 이 전극에 첨가된 경우에는 이들 금속이 전극표면에 노출된 양에 비례하는 효과만이 나타났다. The semiconducting property of Sb-doped tin oxide thin film electrode was investigated and the electrocatalytic effect of this electrode for $SO_2$ (or sulfite, bisulfite ions) oxidation reaction was studied under various conditions. The anodic oxidation of $SO_2$ at tin oxide thin film electrode commenced at lower potential with increasing pH, and good electrocatalytic effect was shown of $SO_3^=$ oxidation in basic solution. In the acidic solutions the electrocatalytic effect of platinum-or palladium-incorporated tin oxide electrode was found to be due to the sites of Pt or Pd exposed on the electrode surface. The electrocatalytic effect of tin oxide electrode was distinctive from that of Pt-or Pd-containing electrodes.

Thrombocytopenia with decreased megakaryocytes is a rare disorder characterized by thrombocytopenia due to a total absence or a marked reduction in the number of bone marrow megkaryocytes. We experienced a case of thrombocytopenia with decreased megakaryocytes in a 15-year-old girl, who was admitted with chief complaints of epistaxis and purpura on the lower extremities. There was a marked decrease of megakaryocytes in the marrow, and only minimal changes in other hematopoietic cell lines were seen. Follow-up studies, including bone marrow aspiration and biopsy which were performed eight months later, revealed typical features of aplastic anemia.

BACKGROUND:: Gliotoxin, a fungal metabolite, has been known to show strong immunosuppressive properties, although its mechanisms are not completely understood. In this report, the authors investigated the mechanism whereby gliotoxin has anti-inflammatory properties in vitro and in trinitrobenzene sulfonic acid-induced colitis. MATERIALS AND METHODS:: Body weight, histological scores, and myeloperoxidase activity were evaluated in trinitrobenzene sulfonic acid colitis. Nuclear factor-&kgr;B (NF-&kgr;B) p65, tumor necrosis factor-α, interleukin (IL)-1&bgr;, IL-12, and intercellular adhesion molecule-1 were detected by immunohistochemical staining. IL-8 secretion was measured by an enzyme-linked immunosorbent assay. Heme oxygenase-1 (HO-1) expression and I-&kgr;B degradation were analyzed by Western blot. RESULTS:: Pretreatment of human epithelial HT-29 cells with gliotoxin significantly blocked the I-&kgr;B degradation and NF-&kgr;B p65 nuclear translocation induced by tumor necrosis factor-α or IL-1&bgr;; these were parallel with the inhibition of IL-8 secretion and intercellular adhesion molecule-1 expression in the same cells. Interestingly, gliotoxin induced HO-1 in HT-29 cells and, in turn, inhibition of HO-1 activity by a zinc protoporphyrin IX reversed the effects of gliotoxin in terms of I-&kgr;B degradation, intercellular adhesion molecule-1 expression, and IL-8 production. In trinitrobenzene sulfonic acid colitis, gliotoxin administration significantly improved the clinical and histopathological symptoms. Notably, gliotoxin also induced HO-1 in the colonic mucosa and zinc protoporphyrin IX reversed the protective effects of gliotoxin in trinitrobenzene sulfonic acid colitis. CONCLUSIONS:: These results demonstrate for the first time that the anti-inflammatory actions mediated by gliotoxin include HO-1 induction and the subsequent blockade of NF-&kgr;B-dependent signaling pathways in vitro and in vivo. The current results also demonstrate that gliotoxin may be an effective agent for the treatment of diseases characterized by mucosal inflammation.
