Objective To study the influences of dichloromethane extraction from crude and processed Cornus Officinalis on bone marrow cells of aging mice induced by D-galactose. Methods DNA damage of bone marrow cells of aging mice induced by D-galactose was detected by the comet assay, the expression of p53 mRNA was detected by RT-PCR. Results The tail formation rate of model group was significantly higher than the rate of control group (P

PURPOSE: This study was done to identify the effect of nursing organizational culture on empowerment as perceived by new clinical nurses. METHODS: For the objective a sample of 175 new nurses from secondary/tertiary hospitals having not less than 250 beds located in B city was selected to complete a questionnaire. The collected data were analyzed using descriptive statistics, t-test, One-way ANOVA, Scheffe's test, Pearson correlation coefficients and simultaneous multiple regression with the SPSS 14.0 software program. RESULTS: As for nursing organizational culture as perceived by the respondent, relation-oriented culture had the highest average score (3.60+/-.63) out of a possible 5 points followed by hierarch-oriented culture, innovation-oriented culture and task-oriented culture with 3.45+/-.30, 3.19+/-.53 and 3.05+/-.46, respectively. The respondents' level of perceived empowerment was 3.06+/-.41. The factors influencing empowerment according to nursing organizational culture were innovation-oriented and relation-oriented culture in that order. These 2 variables were statistically significant predictors and explained 48.6% of the variance in empowerment. CONCLUSIONS: The results of this study indicate that emphasis should be given to nursing organizational culture strengthened by innovationoriented and relation-oriented culture, rather than task-oriented and hierarch-oriented culture, in order to foster harmonious empowerment among nurses at all levels.

Aim To study the chemical constituents of Cypripedium tibeticum. Methods Compounds were isolated by repeated silica gel chromatography and purified on Sephadex LH-20 and structures were determined by spectral analysis. Results Cypritibetquinones A and B were isolated from the ethyl acetate residue and their structures were determined as 7-hydroxy-2-methoxy-1, 4-phenanthraquinone ( 1 ) and 7-hydroxy-2,10-dimethoxy-1,4-phenanthraquinone ( 2 ), respectively, by extensive spectral analyses. Conclusion Cypritibetquinones A and B are two new phenanthraquinones.

Interleukin-6(IL-6) is a multifunctional cytokine, and deregulated IL-6 gene expression has been implicated as being involved in the pathogenesis of a number of diseaaes. So we measured the serum level of IL-6 to find a relationahip between uterine cervical cancer and serum IL-6 level. The serum levels of IL-6 were meesured m 54 patients adrnitted to the Severance hospital, from August, 1992 to February, 1993, of whom 27 patients were diagnosed as invasive cancer of cervix, 17 as CIN, and also utilizing 10 patiente diagnosed as uterine myoma as a control group for matched age and parity. The average serum level of IL-6 in invasive cancer, CIN, and uterine myoma were respectively 30.33pg/ml, 37.27pg/ml, and 12.45pg Jml. In 22% af cervical cancer patients (6 of 27), and 27% of CIN patients (4 of 17) studied blood levels of II-6 were detected whereas only 10% of uterine myoma (1 of 10) shorved the same result. However, the difference does not seem to be statistically significant, There was no statistically significant difference among any of the groups, and age and stage did not show any significant cmrelation, and the results need furt,ber investigations.
