Background: The objective was to study the effect of Scutellaria baicalensis Georgi ethanol extracts (SBGE) on immune and anti-oxidant function in U14 tumor-bearing mice. Materials and Methods: U14 tumor-bearing mice were randomly divided into eight groups: a control group, a cyclophosphamide (CTX) group, three dose groups of SBGEI (high, medium, low), and three dose groups of SBGEII (high, medium, low). After two weeks, the thymus and spleen weight indices of mice bearing U14 cervical cancer were calculated. Enzyme linked immunosorbent assays (ELISA) was used to determine the levels of serum IL-2, TNF-${\alpha}$, IL-8, and PCNA. MDA activity and SOD activity in plasma were measured with detection kits. Results: In the SBGE groups, thymus weight and spleen weight indices of U14 tumor-bearing mice were significantly higher than in the control group or CTX group (p<0.05). Compared to control group, the levels of serum IL-2 and TNF-${\alpha}$ in U14 tumor-bearing mice increased significantly, whereas the contents of serum IL-8 and PCNA decreased (p<0.05). The activity of SOD increased with the growing dose of SBGE, while the activity of MDA decreased significantly in the highe-rdose groups of SBGE. Conclusions: These findings suggested that SBGE, especially at high dose, 1000 mg/kg, showed significant immune and anti-oxidant effects infU14 tumor-bearing mice, which might be the mechanisms of SBGE inhibition of tumor growth.

Background: Cervical cancer is listed as one of high-incidence endemic diseases in Xinjiang. Our study aimed to evaluate the expression of TLR9 in uterine cervical tissues of Uyghur women and examine associations with clinicopathological variables. We further characterized the direct effects of TLR9 upon the selective silencing of human papillomavirus (HPV) E6 and E7 oncoprotein expression in HPV 16-positive human cervical carcinoma cells treated with siRNA in vitro. Materials and Methods: Immunohistochemistry was applied to evaluate TLR9 expression in 97 formalin-fixed paraffin-embedded cervical samples from Uyghur women; 32 diagnosed with cervical squamous cell carcinomas (CSCC), 14 with low-grade cervical intraepithelial neoplasias (CINI), 10 medium-grade (CINII), 24 high-grade (CINIII), and 17 chronic cervicitis. $BLOCK-iT^{TM}$ U6 RNAi Entry Vector $pENTR^{TM}$/U6-E6 and E7 was constructed and transfected the entry clone directly into the mammalian cell line 293FT. Then the HPV 16-positive SiHa human cervical carcinoma cell line was infected with RNAi recombinant lentivirus. RT-PCR and Western blotting were used to determine the expression of TLR9 in both SiHa and HPV 16 E6 and E7 silenced SiHa cells. Results: Immunohistochemical staining showed that TLR9 expression was undetectable (88.2%) or weak (11.8%) in chronic cervicitis tissues. However, variable staining was observed in the basal layer of all normal endocervical glands. TLR9 expression, which was mainly observed as cytoplasmic staining, gradually increased in accordance with the histopathological grade in the following order: chronic cervicitis (2/17, 11.8%)

Background: The Pap smear has an important value in the early diagnosis of cervical cancer, a serious problem in womens health. This study aimed to determine the status of Turkish women regarding participation in Pap smear testing and affecting factors. Materials and Methods: This descriptive study was conducted on married women between 18-61 years of age selected from those who applied to the Obstetrics and Gynaecology Polyclinic of Atat$\ddot{u}$rk University in Erzurum between June-August 2010 for any reason. Data were collected using a questionnaire determining socio-demographic features and analyzed by descriptive statistics (mean, Sd, range, frequency, percentage) and Chi-square test. A level of p<0.05 was considered statistically significant. Results: Sixty six of the 301 women (21.9%) indicated that they heard a Pap smear test and 16.6% of women had experienced a test. The number of women participating increased with age, duration of marriage, number of births, knowledge about the Pap smear and perception of risk for cervical cancer. Conclusions: The importance of the Pap smear test needs to be explained to Turkish women by health staff, to increase awareness and participation in regular screening.

Twenty-five patients with perforation of esophagus were managed at Pusan National University Hospital, from 1981 to 1993. The hospital course of 14 of these patients was evaluated with a special emphasis on the cause and location of perforation, clinical presentation, time elapsed from perforation to treatment, method of treatment, and outcome. Patients with anastomotic leak and cancer were excluded.The perforation was iatrogenic in 7 patients, spontaneous in 5, ingestion of foreign body in 1, and traumatic in 1. There were 7 cervical perforations, 2 upper thoracic perforations, and 5 lower thoracic perforations. Chest pain, fever, and dyspnea were frequent symptoms. Esophagography was most diagnostic [11 patients] but thoracentesis was of little diagnostic aid.Antibiotics were administered intravenously to all patients:hyperalimentation was accomplished intravenously in 11, and nasogastric suction was used in all cases. No patient required any surgical procedure, minor or major.

A new biosurfactant producer was isolated from palm-oil-contaminated soil and later identified through morphology and DNA sequencing as the yeast-like fungus Exophiala dermatitidis. Biosurfactant production was catalyzed by vegetable oil, supplemented with a basal medium. The culture conditions that provided the biosurfactant with the highest surface activity were found to be 5% palm oil with 0.08% $NH_4NO_3$, at a pH of 5.3, with shaking at 200 rpm, and a temperature of $30^{\circ}C$ for a 14-day period of incubation. The biosurfactant was purified, in accordance with surfactant properties, by solvent fractionation using silica gel column chromatography. The chemical structure of the strongest surface-active compound was elucidated through the use of NMR and mass spectroscopy, and noted to be monoolein, which then went on to demonstrate antiproliferative activity against cervical cancer (HeLa) and leukemia (U937) cell lines in a dose-dependent manner. Interestingly, no cytotoxicity was observed with normal cells even when high concentrations were used. Cell and DNA morphological changes, in both cancer cell lines, were observed to be cell shrinkage, membrane blebbling, and DNA fragmentation.

연구목적: 3년마다 정기적인 자궁경부암 조기검진을 받도록 권고하고 있는 수검권고안은 검진행동 유발요인으로써 자궁경부암 검진참여의 가능성을 증진시키는 주요 영향요인으로 작용하고 있다. 본 연구는 보건의료 접근성과 보건의료인의 특성이 자궁경부암 조기검진 수검권고에 미치는 영향을 살펴보고자 시도되었다. 연구방법: 본 연구에서 재분석된 한인여성 건강조사자료는 미국 캘리포니아주 알라메다와 산타클라라 카운티에 거주하는 한인여성 865명을 대상으로 2002년에 전화설문조사로 수행되었다. 수검권고안에 영향을 미치는 주요 예측인자를 살펴보기 위해 로지스틱 회귀분석을 수행하였다. 연구결과: 조사대상자 중 37.9%만이 지난 3년간 자궁경부암 조기검진 참여에 관한 수검권고를 받은 것으로 나타났다. 수검권고의 주요 예측인자는 건강보험 가입여부, 지난 1년간의 의사방문횟수, 정기적으로 방문하는 보건의료인의 특성인 것으로 나타났다. 또한 보건의료 접근성에서는 공공의료보험 또는 사보험 여부와 관계없이 건강보험에 가입한 여성들이 수검권고를 더 많이 받은 것으로 나타났다. 특히 보건의료인의 특성 중 인종과의 관련성을 살펴보면, 한인이 아닌 타 인종의 여성 의사로부터 가장 많이 검진참여에 관한 수검권고를 받았고(OR=6.21, 95% CI=2.63, 14.66), 다음으로 한인 남성 의사(OR=2.19, 95% CI=1.30, 3.68), 비한인 남성 의사로부터 수검권고를많이 받았다(OR=2.07, 95% CI=1.15, 3.71). 결론: 캘리포니아주의 2개 카운티에서 거주하는 한인여성을 대상으로 보건의료 접근성과 보건의료인의 특성이 자궁경부암 조기검진 수검권고에 미치는 영향을 분석한 결과, 한인여성들의 건강보험 가입여부 및 의사방문 수준, 보건의료인의 인종이 수검권고와 관련이 있는 것으로 나타났다. 이는 한인여성들의 자궁경부암 조기검진 수검률 향상 및 자궁경부암 이환률과 사망률을 감소시키기 위한 수행전략 개발에 중요한 기초자료로 활용될 수 있다.
