Purpose: Cervical cancer can be prevented by regular cervical screening. Embarrassment has been reported as one important barrier to cervical screening uptake. The absence of appropriate instrumentation, however, has limited our understanding of the links between embarrassment and health care outcomes. The purpose of this study was to evaluate psychometric attributes of the uterine cervical cancer screening embarrassment questionnaire. Methods: A convenience sample for field study was recruited from four gynecological clinics in Gyeongju, Korea. Within a cross-sectional descriptive design, 339 women who had cervical screening completed self-administered measures of embarrassment including a visual analogue, general medical embarrassment, dispositional embarrassment, and Pap smear related negative emotion. Results: Rasch analysis of items demonstrated the evidence of one-dimensional construct and good 7-point rating scales functioning. Factor analysis revealed that uterine cervical cancer screening embarrassment was comprised of two domains-bodily manifestations and perceiving an undesirable social face. Construct validity was demonstrated by a high subscale-to-subscale correlation. Convergent and discriminant validity was evidenced by significant correlations with a 100 mm VAS scale, general medical embarrassment, and Pap smear related negative emotion. Known-group validity was established by comparing women with high versus low trait embarrassment. Both two sub-scales and overall scale demonstrated good internal reliability. Conclusion: The Uterine uterine cervical cancer screening questionnaire is a reliable and valid instrument suited to assessing the manifestations of embarrassment during screening. The use of instrument can be extended to understand the client's embarrassment undergoing health examinations which require the exposure of their private parts.

Human blood clotting (coagulation) factor 9 cDNA which codes for 461 amino acid has been cloned by screening human fetal liver cDNA library using PCR. This 1.4 kb cDNA spanning from the ATG initiation codon to the TAA termination codon was cloned into bacterial .expression vector pGEX-2T, generating pGEX-F9 plasmid. The plasmid pGEX-F9 expresses about 73 kDa GST (Glutathione S-transferase)-Factor 9 fusion protein when introduced into E. coli. Western blot analysis using polyclonal antibody raised against human factor 9 confirmed this fusion protein contains factor 9 protein. The level of GST-factor 9 expression was about 20% of total protein and the purification of fusion protein was efficiently achieved by using GST agarose bead based on one step purification protocol.

As an initial effort to elucidate RNA: protein binding in a way to regulate translation initiation and phosphorylation, a cDNA encoding a double-stranded RNA binding factor (RBFII)was isolated from Hela ZAPII cDNA library by affinity screening using [$\alpha$$^{-32}$P] UMP-labeled HIV Rev-responsive element(RRE) RNA. The nucleotide sequence of RBF (or TRBP) cDNA except the 5’end. At the 5’end, This common ORF was fused in-frame to N-terminal residues of Lac-Z through a unique 138 nt sequence encoding 46residues in the case of RBFII and a 63 nt sequence encoding 21 residuces in the case of RBFI. The context of ATG appearing first in the sequences suggests that both these cDNA inserts are incomplete at the 5’end.

The importance of repeat screening for stomach cancer is well known to decrease deaths from stomach cancer. This study was aimed at assessing practice behaviors and to identify related factors in the aspects of demographic factors, health status and cancer risk recognition, attitude to cancer screening, health behaviors, and inhibiting or facilitating factors to stomach cancer screening in an urban area. Data was collected through self-administered questionnaires from 403 people aged 40 to 69 years from April 23th to May 15th, 2002. Practice behaviors were classified as : "ever" or "never", and "repeat" or "not repeat" grouped based on a recent 5 year screening history. The results were as follows: 1. Among the 403 subjects: "the ever group" was 23.8% and "the repeat group" was 4.0%, The rates of screening were 20.5% for men, 27.8% for those women, and 27.3% for aged 40-49, 24.5% for those aged 50-59, 19.0% for those aged 60-69. The rates of repeat screening were 4.0% for men, 4.1% for women, and 2.9% for those aged 40-49, 6.3% for aged 50-59, 2.5% for those aged 60-69. 2. The main factors associated with adherence to gastric cancer screening were education(post high school vs below : OR=2.44), previous cancer screening(yes vs no : OR=2.61), belief in personal health(no vs yes : OR=2.72), health status(unhealthy vs healthy : OR=3.40), possibility of cancer compared to others(low vs not low : OR=2.56), and regular exercise(yes vs no : OR=2.94). The main factor associated with adherence to gastric cancer repeat screening was other cancer screening(yes vs no : OR=6.33). Consequently, there is a need to change the recognition of the importance and necessity of stomach cancer screening in healthy conditions through health education, and to perform multiple screening tests each visit.

With ultraviolet and visible light exposure, some pharmaceutical substances applied systemically or topically may cause phototoxic skin irritation. The major factor in phototoxicity is the generation of reactive oxygen species (ROS) such as singlet oxygen and superoxide anion that cause oxidative damage to DNA, lipids and proteins. Thus, measuring the generation of ROS can predict the phototoxic potential of a given substance indirectly. For this reason, a standard ROS assay (ROS assay) was developed and validated and provides an alternative method for phototoxicity evaluation. However, negative substances are over-predicted by the assay. Except for ultraviolet A (UVA), other UV ranges are not a major factor in causing phototoxicity and may lead to incorrect labeling of some non-phototoxic substances as being phototoxic in the ROS assay when using a solar simulator. A UVA stimulator is also widely used to evaluate phototoxicity in various test substances. Consequently, we identified the applicability of a UVA simulator to the ROS assay for photoreactivity. In this study, we tested 60 pharmaceutical substances including 50 phototoxins and 10 non-phototoxins to predict their phototoxic potential via the ROS assay with a UVA simulator. Following the ROS protocol, all test substances were dissolved in dimethyl sulfoxide or sodium phosphate buffer. The final concentration of the test solutions in the reaction mixture was 20 to $200{\mu}M$. The exposure was with $2.0{\sim}2.2mW/cm^2$ irradiance and optimization for a relevant dose of UVA was performed. The generation of ROS was compared before and after UVA exposure and was measured by a microplate spectrophotometer. Sensitivity and specificity values were 85.7% and 100.0% respectively, and the accuracy was 88.1%. From this analysis, the ROS assay with a UVA simulator is suitable for testing the photoreactivity and estimating the phototoxic potential of various test pharmaceutical substances.

Purpose: The aim of this study was to identify risk factors for breast cancer and early screening behavior in women in the community. Method: The participants were 125 women residing in W city. Data was collected using an instrument developed by the researchers. Analysis was done using descriptive statistics, and the $x^2$ test. Result: For risk based on the Gail Model, age (above 50 years) had a distribution of 24.8%, first degree family history, 4.9%, age at first full term pregnancy, 13.8%, and benign breast cancer history, 4.9%. For risk based on other common risk factors, menopause had a distribution of 20.7%, did not breast feed, 15.4%, history of HRT, 7.3%, meat preference, 35.0%, and history of smoking or drinking, 2.4% and 43.5%, respectively. There was a significant difference in BSE and mammography screening behavior ($x^2=22.5$, p<.00), but no difference in distribution of risk factors and screening behavior. Conclusion: For effective prevention of breast cancer, it is necessary to develop an instrument for risk assessment and, through assessment, select women at high risk. It is also necessary to provide education and appropriate recommendations on screening behavior.

Doxorubicin, one of the clinically most useful anticancer agents, is used alone or in combination with other drugs against a wide variety of tumors, recently. But cancer cells developed resistance to this agent in many ways. This resistance is an important limiting factor of doxorubicin for anticancer drug. We newly established doxorubicin-resistant HCT15/CL02 subline from parental HCT15 human adenocarcinoma colon cancer cells. HCT15/CL02 revealed resistance to doxorubicin about 85-fold of its parental cells, and it also revealed cross-resistance to actinomycin D, etoposide and vinblastine but not to displatin and tamoxifen. And verapamil, a reversal agent of multidrug-resistance (MDR) by P-glycoprotein, elevated the cytotoxicity of doxorubicin against both HCT15 and GCT15/CL02 cells. But the relative resistant rate was not reduced. Verapamil had no effects on the tosicity of cisplatin to the both cell lines. These results indicate that HCT15/CL02 cells have some functionally complex mechanisms for MDR.

The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics.
