While augmentation of 5-fluorouracil (5FU) cytotoxicity by folinic acid (FA) has clearly been demonstrated in vitro, its value in human is controversial. Unfortunately, essentially all tumors studied in vivo have been murine and none were transitional cell carcinoma (TCC); no in vivo studies of FA+5FU against TCC xenografts have been performed. The present study was initiated to test the effects of FA on 5FU induced cytotoxicity in two human bladder cancer xenografts, DU4184 and DU4284, and to further test the sequence dependence of FA+5FU synergism. To perform the in vivo chemosensitivity assay, we used modified nude mouse subrenal capsule assay. Before treatment, the mice were randomly allocated into four groups. Group A was given normal saline only as a control, group B was given 5FU (100 mg/kg i.p.) only, and group C was given FA (100 mg/kg i.p.) and 5FU simultaneously and group D was given FA and one hour later 5FU. Before treatment and after treatment tumor volumes were measured and tumor growth ratio (TGR) of each group was calculated. TGRs of group A, B, C, and D were 6.1+/-0.6, 3.8+/-0.3, 3.8+/-0.4, and 3.0+/-0.2, respectively.No difference in cytotoxicity was seen if 5FU was given simultaneously with FA (group C). However, pretreatment with FA one hour prior to 5FU resulted in statistically significant potentiation of 5FU efficacy (group D) (p<0.05). Using this preferred dose schedule, DU4184 vs. DU4284 (+/- FA) was evaluated. Comparative sensitivity of the two lines revealed that DU4284 is relatively resistant to 5FU. FA significantly enhanced the cytotoxicity of 5FU on both DU4184 and DU4284 xenografts (p<0.05, and p<0.01, respectively) and had a substantially greater impact in the intrinsically more 5FU-resistant tumor (DU4284). It is concluded that FA is an effective chemosensitizer of 5FU in vivo against human TCC. Nevertheless, dose schedule is critical; pre-loading of the tumor with FA prior to 5FU is essential. However, as yet undefined intrinsic biochemical differences between tumors [such as thymidine salvage pathways (not generally assessable by standard in vitro assays)] may modulate the extent of such efficacy. Further preclinical study with an expanded TCC xenograft battery is necessary and should be linked with a study of biochemical correlates to identify phenotypic differences in FA chemosensitivity of those benefiting from this regimen.

OBJECTIVES: This study aimed to evaluate the primary care quality of a public health center in a rural area using the Korean Primary Care Assessment Tool (KPCAT). It also examined some methodological issues in applying the KPCAT and interpreting its results. METHODS: Seventy-nine patients who had visited their doctor more than four times responded to the KPCAT questionnaire. Descriptive statistics and a radar chart were used in analyzing data. Sign test was used to test the KPCAT score difference by don't know option scoring methods. RESULTS: Median and interquartile range of the public health center's KPCAT scores were forty-five and sixteen points, respectively. Only the median of the first contact domain reached the expected value of seventy-five points. The proportions of those who scored under the expected value were under fifty percent in two of four comprehensiveness items, all of three coordinating function items, two of five personalized items and all of four family/community orientation items. There were some methodological issues including, how to score don't know option and make sure response scale consistency. CONCLUSIONS: There was much room to improve the primary care quality of the rural public health center. Especially, improvement is needed in the domain of coordinating function and family/community orientation. We also hope that methodological improvement of the KPCAT contributes to more valid and reliable primary care assessment.

Serum HBsAg, AntiHBs, HBeAg, AntiHBe, and AntiHBc were detected by radioimmunoassay in 39 patients with acute viral hepatitis, 79 patients with chronic hepatitis, 30 patients with liver cirrhosis, 16 patients with primary hepatocellular carcinoma, 14 patients of HBsAg carriers and 129 cases of controls: 78 cases of normal level of SGOT, SGPT, and 51 cases of elevated level of SGOT, SGPT. Following results were obtained: 1. HBsAg was detected in 66.7% of acute viral hepatitis, 63.3% of chronic hepatitis, 36.7% of liver cirrhosis, 81.3% of primary hepatocellular carcinoma and 27.1% of controls. 2. AntiHBs was positive in 0% of acute viral hepatitis, 21.5% of chronic hepatitis, 36.7% of liver cirrhosis, 31.3% of primary hepatocellular carcinoma, 0% of carrier and 44.2% of controls. 3. HBeAg was detected in 45.6% of chronic hepatitis, 23.3% of liver cirrhosis and 31.3% of primary hepatocellular carcinoma. 4. Among chronic liver diseases, antiHBe was positive in 56.3% of primary hepatocellular carcinoma, 23.3% of liver cirrhosis and 20.3% of chronic hepatitis. 5. AntiHBc was detected in most of all examinees and the significance of presence of AntiHBc does not seem to represent liver disease itself but the evidence of infection of HBV. 6. Among 14 HBV carriers, 6 cases presented with abnormal SGOT, SGPT. 7. All HBV markers were negative in 5.1% of acute viral hepatitis, 5.1% of chronic hepatitis and 14.7% of controls: 17.6% of subjects with abnormal SGOT, SGPT and 12.8% of subjects with normal SGOT, SGPT. 8. Beside of HBV, other causes, such as non A, non B virus, Delta-agent, other viruses or related factors should be excluded among the patients with evidence of HBV infection associated with elevation of SGOT & SGPT.

OBJECTIVES: Chromosomal anomalies are common disease entity among genetic diseases. But there are scanty reports about the status of chromosomal abnormalities in Korean. In addition, the comprehensive multi-center study of chromosomal abnormalities in Korean has never been performed. METHODS: We have collected 1,793 cases (394 abortuses; 198 chorionic villi; 1,060 amniotic fluid cells; 141 fetal blood), which showed abnormal karyotype results from twenty three cytogenetic centers in Korea from the year of 1977 to 1999. RESULTS: In abortuses, numerical chromosomal abnormalities was 85%, and structural abnormalities was 13% and the most frequent anomaly was trisomy 16. In chorionic villi, numerical anomaly was 60.0% and structural anomaly was 31.3% and the most frequent karyotype was Down syndrome. In amniotic fluid cells, structural anomaly exceeded the number of numerical anomaly and the most frequent anomaly was Down syndrome. In fetal blood, numerical anomaly was 63.8% and the most frequent karyotype was trisomy 18 (23.4%) CONCLUSIONS: This may be the first comprehensive and multi-center study in Korea. The proportion of the abnormal karyotypes in each specimens was different from each other. Based on this study, the more comprehensive study should be performed to all the Korean population.

Occupational dermatosis is one of the most prevalent occupational disorders. However, the extent of the occupational dermatoses including incidences and prevalencies of each disease entity, and etiologic materials are not yet well stated in Korea. Authors reviewed the literatures on the statistic data and reports on the occupational dermatoses, and surveyed on the occupational dermatoses in two factories, and surveyed the physicians responsible to the occupational dermatoses with formed questionnaire. The results are as follows; 1. Among medical journals published since 1964, there were 31 articles on the occupational dermatoses. Of 31 articles, 18 were case reports and all others were review articles. Of 18 case reports, 9 were epidemiologic survey. The Workers' Periodic Health Examinations revealed that prevalence of the occupational dermatoses was highest(4.36 per 10,000 workers) in 1974, but number of the cases reported were decreased sharply since 1978 with some tendency to increase since 1987. There were 2,240 reported cases of occupational dermatoses between 1966 and 1992, which is 1.90% of all the reported occupational diseases. Skin infection and injuries due to chemicals were most frequent and there were 6 cases of skin cancer. 2. In an epidemiological survey on the dermatoses among 995 workers in a metal product manufacturing factory and 225 workers with acne, 130 workers with scar, 123 workers with deformity of toe nails. Scars, photosensitivity dermatitis, deformity of finger and toe nails, and acne were more prevalent in the metal product manufacturing factory(p<0.05). In the metal product manufacturing factory, workers treating organic solvents and oils had more dermatoses than those without treating the materials(p<0.05). On the skin patch performed on 16 workers in the metal product manufacturing factory, there were 8 cases of irritation dermatitis and 5 cases of contact dermatitis. Prevalence of contact dermatitis in the metal product manufacturing factory was 1.3%. 3. On the questionnaire survey, 34 dermatologists, 29 doctors of preventive medicine, and 22 family physician replied. The proportion of occupational etiology among all dermatoses assumed by the physicians were below 9%, and the most important occupational dermatosis in Korea was contact dermatitis. Main etiologic materials related to the occupational dermatosis were organic solvent, acid and alkali, and metals. The reason for the scarcity of report of occupational dermatoses were difficulty in diagnosis and physician's ignorance of the occupational etiology. They replied that to prevent the occupational dermatosis in the workplace, the use of protective devices was most important, and development of diagnostic criteria on the occupational dermatoses is urgent. Above results shows us that there is many workers with occupational dermatoses, but they are mostly unreported. Measures to prevent and manage the occupational dermatoses are not satisfactory at present. Hence, authors suggest measures for the precises diagnosis, report and prevention of the occupational dermatoses. a. Dernatikigustm orevebtuve physician, and industrial hygienist should work as a team to examine the high risk group and establish the preventive measures. b. Disease entities, diagnostic criteria of occupational dermatoses should be listed, criteria for the compensation and job fitting at recruitment should be established, and manual for the proper treatment and effective prevention of each occupational dermatosis should be developed. c. Patch test antigens against each occupational category should be developed and it should be available to any physicians responsible. d. To facilitate the diagnosis of occupational dermatoses by the doctors responsible for the Workers' Periodic Health Examination, development of standardized questionnaire, education on the techniques of the patch test, and cooperation with the dermatologist in diagnosis of occupational dermatoses is essential.
