A considerable body of evidence has been accumulated suggesting that invasive squamous cell carcinoma develops from cervical intraepithelial neoplasia(CIN). Most women with invasive cancer of the cervix are from lower socioeconomic groups, have begun heterosexual activity early in life, marry early, are multiparous, and have many sexual partners. Although the epidemiology of the cervical cancer is known well, the pathogenesis of the cervical cancer from CIN is subtle yet. Apoptosis, including the programmed cell death, is important event in normal cell turnover and maintenance of adult tissues. Apoptosis exerts a homeostatic function in relation to tissues dynamics, as the steady state of continuously renewing tissues achieved by a balance between cell replication and cell death. The specific labelling of nick ends of fragmented DNA was used to see the apoptotic cells from normal epithelium of the cervix to invasive cervical cancer. The apoptotic cells were found normally in the parabasal layer of the epithelium. As the grade of CIN increase, the apoptotic cell were found in superficial of the cervix and number of the apoptotic cell were increased. In the cervical cancer, the apoptotic cell were found in the cancerous tissues more than in the normal epithelium. This results suggest that the cell proliferation is more important than the inhibition of the apoptosis in the carcinogenesis of the cervical cancer.

OBJECTIVE : To analyze the methylenetetrahydrofolate reductase (MTHFR) mutation in recurrent spontaneous abortion associated with hyperhomocysteinemia. MATERIAL AND METHOD: The blood Sample of habitual aborter with high fasting homocysteine level was tested by PCR-RFLP method. RESULTS: The patient was found to be a homozygosity for MTHFR gene mutation that was confirmed by the finding which is consistent with the mutation at the nucleotide 677 C to T, Corresponding to Ala to Val. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. Therefore, the MTHFR mutation should be examined in the workup of recurrent spontaneous abortion showing hyperhomocysteinemia.

In Sprague Dawley (SD) rats, antibodies against strains of Orinentia tsutsugamushi, Kato, Karp and Gilliam, were produced in order to investigate their longevity and cross-reactivities to their corresponding homologous and heterologous antigens. By immunofluorescence assay (IFA) of IgG and IgM, it was shown that the immunity to the homologous strains persisted at a higher level (longevity of at least 34 weeks with higher IFA titers). On the other hand, the immunity to the heterologous strains persisted at a lower level (longevity of 10 to 34 weeks with lower IFA titers). Since infection with one strain of O. tsutsugamushi does not preclude reinfection with other strains, understanding of the antigenic diversity of O. tsutsugamushi and duration of the immunity to both homologous and heterologous strain is very important in diagnosis of scrub typhus.

BACKGROUND: Anesthesiologists should understand the physiology of intraocular pressure and the implications of anesthetic drugs and maneuvers on intraocular pressure(IOP). Although most anesthetics reduce IOP, succinylcholine causes a transient but significant increase in IOP. And thiopental by itself does not prevent to increase blood pressure, IOP. This study was designed to evaluate the preventive effect of propofol on IOP changes during tracheal intubation. METHODS: IOP was measured with a hand-held applanation tonometer in the eye. Baseline(control) IOP was measured before the induction of anesthesia(stage 1) and serial measurements of IOP were made after administration of the induction agent before intubation(stage 2), immediately after intubation(stage 3) and 10 minutes after intubation(stage 4). Heart rate and systolic blood pressure were recorded simultaneously. According to induction agent and neuromuscular blocker, the 60 patients were divided into control group(C; thiopental, succinylcholine), pretreatment group(T) using defasciculation dose of vecuronium bromide, propofol group(P; propofol, succinylcholine) and vecuronium group(V; propofol, vecuronium bromide). RESULTS: Administration of either propofol or thiopenal resulted in a significant reduction in IOP(P<0.01). At stage 2, IOP of gpoup P and V were significantly lower than that of group C(P<0.05). At stage 3, IOP increased significantly compared to the values of stage 1 in all group(P<0.01). At stage 4, IOP decreased significantly compared to the values of stage 1 in all group(P<0.01), but there was no significant difference between groups in IOP at stage 4. CONCLUSIONS: Propofol may be a useful induction agent of general anesthesia for opthalmic surgery, but cannot prevent to increase IOP during endotracheal intubation.

PURPOSE: Intravesical instillation of bacillus Calmette-Guerin(BCG) is an established and effective therapy for the superficial bladder carcinoma. The viability of BCG is crucial for the induction of a local immune response as well as effective therapy of recurrent superfical bladder carcinoma. Lubricants are used to facilitate catheterization during intravesical instillation of BCG. Moreover bacteriostatic components contained in them have potential to reduce the viability of the BCG. To verify this assumption, inhibitory effect of four commercially available lubricants on the BCG growth was analyzed. MATERIALS AND METHOD: Four different lubricants and their components were co-incubated with Connaught strain BCG and the resultant growth of BCG was assessed. RESULTS: Significant impairment of BCG viability with lubricants was noted. Chlorhexidine digluconate which is the component of lubricant was considered as responsible for this inhibition. CONCLUSIONS: During intravesical BCG, lubricants might reduce the number of viable BCG in clinical use. For this reason, during intravesical immunotherapy with BCG small amounts of lubricants should be used for urethral catheterization and use of lubricant which does not contain bacteriostatic agent should be considered.

As flow cytometric analysis using paraffin-embedded tissue was developed by Hedley et al in 1983, retrospective study with large amount of archival material was possible. Many literatures reported that the result of paraffin embedded tissue was compatible with that of fresh tissue. We compared the DNA histograms of 26 cases of colorectal adenocarcinoma in which the analysis was done in both fresh and paraffin-embedded tissues. Aneuploidy in fresh and paraffin-embed-ded tissues was 73.0% and 50.0%, respectively. The concordance rate of fresh and paraffin-em-bedded tissues was 76.8% and six interpreters were agreed in 73.0% of the cases. Because flow cytometric DNA analysis using fresh tissues can detect more aneuploid population than in paraffin-embedded tissue, the former is strongly recommeded in DNA ploidy study. Also careful observation using standard criteria may improve the interpretation of DNA histogram.

PURPOSE: The objective of this study was to define the predictors of health related quality of life(HRQoL) of women caregivers of the demented elderly patients. METHODS: The subjects of this study were 140 pairs of patients with dementia and their caregivers. The characteristics of dementia patients and caregivers, Barthel index and SF-36 were measured in this study. T-test, ANOVA, Pearson correlation coefficient, and stepwise multiple regression were used for data analysis. RESULTS: The health related quality of life(HRQoL) score of women caregivers was 288.35+/-66.10 for norm based scoring. HRQoL of women caregivers was correlated with patients' ADL, severity of dementia, caregivers' age, burden, and family support. The major factors that affected the physical components of women caregivers of patients with dementia was the age of the caregiver, burden, and ADL which explained 36.0% of HRQoL. The main predictors of women caregivers' emotional state was the caregiver's burden. CONCLUSION: Patients' support systems must be implemented to improve the physical HRQoL of caregivers. A caregivers' burden relief program needs to be prepared to increase their emotional HRQoL and further studies and efforts will be needed to evaluate those effects.

PURPOSE: The healthy worker effect is an important issue in occupational epidemiology. This study was conducted to propose a new method to test the relation between exposure and mortality in the presence of the healthy worker effect. METHODS: In this study, the healthy worker hire effect was assumed to operate as a confounding variable of health status at the beginning of employment and healthy worker survival effect as a confounding and intermediate variable of employment status. In addition, the proposed method reflects the length bias sampling caused by changing of an employment status. Simulation studies were also carried out to compare the proposed method with Cox's time dependent covariates models . RESULTS: The theoretical development of the healthy worker survival effect is based on the result that an observation with change of an employment status requires that the survival time without intermediate event exceeds the waiting time for the intermediate event. According to our simulation studies, both the proposed method and Cox's time dependent covariates model which includes the change of employment status as time dependent covariates seem to be satisfactory at 5% significance level. However, Cox's time dependent covariates models without or with the change of employment status as time fixed covariate are unsatisfactory. The proposed test is superior in power to tests based on Cox's model. CONCLUSIONS: The healthy worker effect may not be controlled by classical Cox's proportional hazards models. The proposed method performed well in the presence of healthy worker effect in terms of level and power
