Hysterosalpingograms of 375 patients with infertility were reviewed with reference to radiological features of each pathology and a comparative study of hysterosalpingography and laparoscopy in 36 patients was presented. The results were as follows; 1. In 375 cases infertility, 191 cases (50.9%) were primary infertility and 181 cases(49.1%) were secondary infertility. 2. The peak age distribution was 26 to 30 year old group in 211 cases (56.3%),and the peak duration of infertility was less than 3 years in 256 cases (68.3%). 3. Abnormal uterine findings were 115 cases (30.7%) and there were 73 cases of filling defects, 13 cases of irregularity , 12 cases of uterineflexion, 11 cases of congenital anomaly, and 9 cases of hypoplasia among them. 4. Abnormal tubal findings were 196 cases (52.3%) and there were 103 cases of simple obstruction, 69 cases of hydrosalpinx, and 50 cases of peritubal adhesion among them. 5. Intravasation of contrast media was noted in 42 cases (11.2%). 6. In 36 cases of laparoscopy, 23 cases (63.7%) was agreed to hysterosalpingography. 7. Aothough laparoscopy was better than hysterosalpinography in external anatomy of salpinx and relationship to overay, hysterosalpingography should be important for fundamental study of infertile women because of lower failure rate, lower risk of complications,therapeutic effect, and lower cost.

Purpose: This study aimed to analyze the immunologic profile of children with postinfectious bronchiolitis obliterans (PIBO) in order to approach pathophysiology affected by host factors. Methods: A total of 10 children with PIBO were prospectively enrolled. We obtained information on demographics from their caregiver and electric medical records. Peripheral blood samples were collected before cyclic systemic methylprednisolone therapy and complete blood count, immunoglobulin level and lymphocyte subset were analyzed. Results: The white blood cell count and immunoglobulin level were within the normal range in children with PIBO. The CD4+/CD8+ ratio was not significantly different from those of the healthy control group. A decreased proportion of both central memory T cells (median [interquartile range]; 13.5% [8.3%–16.3%] vs. 18.5% [15.9%–24.1%], P = 0.01) and effector memory T cells (10.3% [5.0%–18.4%] vs. 20.9% [16.6%–26.3%], P = 0.03) in CD4+T cells was observed in the PIBO group compared with those in the control group. In CD8+T cells, the proportion of effector memory T cells (7.8% [4.2%–13.8%] vs. 24.3% [15.3%–27.9%], P = 0.02) and CD45RA+effector memory T cells (16.2% [11.0%–36.6%] vs. 24.2% [17.1%–39.7%], P = 0.04) was decreased in the patient group compared with the control group. Conclusion It is suggested that T lymphocyte subset abnormalities may be associated with a decrease in the ability to differentiate the T cells immediately upon reinfection and induce an effective response to infection. These results may partially explain the pathophysiological individual vulnerabilities to PIBO after lower respiratory tract infections in children.

PURPOSE: Replication-competent adenoviruses (Ads) are promising new modalities for the treatment of cancer. Selective replication of a viral agent in tumor may lead to improved efficacy over non-replicating Ads due to viral multiplication, lysis of the infected cancer cell and spread to surrounding cells. In our previous studies it was shown that the E1B 55 kD-deleted Ad (YKL-1) exhibits tumor specific replication and cell lysis, but with reduced cytolytic effects compared to the wild type adenovirus (Int J Cancer 2000;88: 454-463). Thus, improving the potency of oncolytic Ads remains an important goal for cancer gene therapy. To increase the oncolytic ability of YKL-1, an adenovirus death protein (ADP) gene was reintroduced under the control of a CMV or MLP promoter at the E3 region of the YKL-1, generating an YKL-cADP and YKL-mADP, respectively. MATERIALS AND METHODS: The in vitro cytolytic effect of ADP expressing Ads was evaluated by MTT assay, and the induction of apoptosis by ADP expressing Ads was examined by TUNEL analysis. Finally, the antitumor effect of ADP expressing Ads was demonstrated in C33A xenograft tumor model. RESULTS: The YKL-cADP exerted a markedly enhanced cytolytic effect against H460 and SK-Hep1 cancer cell lines. The TUNEL assay indicated that the ADP-mediated cytotoxicity was largely driven by apoptosis. Finally, the YKL-cADP showed a superior antitumor effect than the YKL-1 or YKL-mADP in C33A xenografts. CONCLUSION: These lines of evidence demonstrate that the YKL-cADP induces efficient cell lysis, which is critical for the addition of therapeutic value to replicating Ads in cancer gene therapy.

BACKGROUND: The New Bethesda System terminology has opened a series of problems about the atypical squamous cells of undetermined significance and low grade squamous intraepithelial lesion categories, particularly on their follow up. METHODS: We observe 12300 Pap smear examination, from jan 1995 to Dec 1999, in the Health promotion Center in a university hospital. Subjects were defined a the Health Promotion Center in a university hospital by electrical record and chart review. RESULTS: We find 48 cases of ASCUS and 33 cases of LSIL. When it is followed up by Pap smear, 34 cases of ASCUS are confirmed normal 19 cases(55.9%), benign cellular change 6 cases(17.6%), ASCUS 5 cases(14.7%), HSIL 4 cases(11.8%) and 27 cases of LSIL are confirmed normal 11 cases(40.7%), benign cellular change 3 cases(11.1%), ASCUS 3 cases(11.1%), LSIL 8 cases(29.6%), HSIL 2 cases(7.4%). 14 cases of ASCUS and 23 cases of LSIL are diagnosed by biopsy. Hostologic results of 14 cases of ASCUS are confirmed cervicitis 10 cases(71.4%), Moderate dysplasia 2 cases(14.3%), carcinoma in sute 2 cases(14.3%) and histologic results of 23 cases of LSIL are confirmed cervicitis 15 cases(65.2%), mild dysplasia 3 cases(13%), moderated dysplasia 3 cases(13%), sever dysplasia 1 cases(4.3%), carcinoma in situ 1 case(4.3%). Pap smear only was used for follow-up at family medicine clinic and 14 cases(29.2%), 4 cases(12.1%) are follow-up loss. CONCLUSION: After it is diagnosed ASCUS or LSIL Lesion of Pap smear in healthy care visitors, Follw-up loss is high in only follow-up Pap smear examination and follow-up results are presented more we severe lesions. To reduce follow-up loss, aggressive diagnosis and managements may be needed more than Pap smear follow-up examination.

Prolactin-secreting adenomas are the most common pituitary tumors resulting in hyperprolactinemia which is one of the most important causes of female infertility with amenorrhea or galactorrhea. Although it is reported that spontaneous pregnancy occured in these patients using bromocriptine treatment or ovulation induction, it is very rare to find a pituitary tumor during a pregnancy by having neurological symptoms of headache, diplopia or visual disturbance. We experienced a case of normal delivery after symptom improvement and maintenance of pregnancy by administration of bromocriptine in a 27 year-old primigravida with diplopia and visual disturbance due to prolactin-secreting pituitary macroadenoma, which is diagnosed by brain MRI scan and serum prolactin level. A brief review of related literature was done.

A prerequisite for the development of a cancer cell selective targeting adenovirus is the generation of adenoviral vectors that lack native receptor binding ability and additionally contain domains redirecting the vector to cancer cell specific receptors. Towards this goal, we have generated an E1B 55kDa-deleted oncolytic and coxoackie and adenovirus receptor (CAR)-binding ablated adenovirus, YKL-K420A. This newly engineered adenovirus resulted in a dramatic reduction of transduction efficiency compared to the control adenovirus, YKL-1, in all of the cell lines tested. The malaria circumsporozoite (CS) protein interacts with glycosaminoglycans (GAG) present on the liver cell surface, and plays a prominent role in sporozoite attachment and invasion into hepatocytes. To redirect the CAR binding ablated adenovirus YKL-K420A to hepatocytes, CS protein epitope (EWSPCSVTCGNGIQVRIK) was incorporated onto the C-terminus of the YKL-K420A fiber protein, generating an YKL-K420A-hepa. The In vitro efficacy and specificity of YKL-K420A-hepa was then evaluated by comparing the cytopathic effect in hepatoma and other cancer cells from different origins. In hepatoma cells, YKL-K420A-hepa exerted upto 20-fold higher cytolytic ability compared to the control adenovirus, YKL-1, in hepatoma cell lines. Treatment with YKL-K420A-hepa also significantly suppressed tumor growth in a hepatoma xenograft tumor model when compared to YKL-1. Taken together, these studies demonstrate that the strategy to alter adenovirus tropism may greatly improve adenoviral utilities in gene therapy applications.

OBJECTIVE: To evaluate the predictive factors associated with the success of medical abortion by misoprostol monotherapy within 24 hours in the first trimester of pregnancy. METHODS: The records of 228 women with miscarriage up to 11 weeks of gestational age who underwent medical abortion by intravaginal misoprostol monotherapy were reviewed. Success of abortion was defined as complete expulsion of the conceptus without the need for surgical intervention. Outcomes of interest were success of abortion within 24 hours following administration of misoprostol. RESULTS: Among 222 women who continued the process of medical abortion for 24 hours, 209 (94.1%) had a successfully completed abortion. Multivariate logistic regression showed that serum β-human chorionic gonadotropin (β-hCG) above 40,000 mIU/mL is significantly associated with failed medical abortion within 24 hours (odds ratio [OR], 7.13; 95% confidence interval [CI], 1.60–37.32; P=0.011). The area under the receiver operating characteristic curve of β-hCG level associated with successful abortion within 24 hours was 0.705 (95% CI, 0.63–0.77; P=0.007). Previous vaginal delivery seems to be significantly associated with successful abortion within 24 hours on univariate analysis (P=0.037), but the association was lost in multivariate analysis. CONCLUSION: Misoprostol monotherapy has a high success rate for first trimester abortion. Women with serum β-hCG less than 40,000 mIU/mL are likely to achieve a successful abortion within 24 hours after intravaginal administration of misoprostol.
