Using Vibrio fluvialis Ⅱ as host bacteria, 19 bacteriophages have been isolated from the 76 samples which were collected from Haliotis discus hannai ～growing seawater in Dalian marine culture company Dalian, liaoning province from May in 1996 to August I 1997. Ultrastructure of 19 bacteriophages were observed with electron to Bradley the results showed that of these bacteriophages belonged to Bradley A type, they have hexagonal heads of bacteriophages were identified with VP1,VP2,VP4,VP8 as representatives respectively. The phages remain stable at pH6. 0～10. 0, moreover VP2,VP4 and VP8 are rather stable at basic pHs. Although the characterization of heat inactivation course of VP4 is different from others, four phages are sensitive to heat and inactivated at 80℃ in 5 minutes. One step growth experiment showed that the eclipse period of VP1,VP2,VP4,VP8 are sensitive to heat and the eclipse period of VP1, VP2, VP4, VP8 are 42, 30, 46, 28 minutes. In this experiment we have isolated at least four different types phages, it suggest that in fact there is a population of phages in the seawater environment. The result of this study provided a way to find the potential value of phages as an indicator of pathogenic microorganisms Vibrio fluvilis Ⅱ in marine environment.

Based on their multiple years of personal experiences in hospital administration,authors of this article point out that medical service,humanistic service,and emotional service should be the core aspects in the current hospital competition.Medical professionalism embodied in the three levels of consciousness,behaviors,and regulations should be the main subject in the research on the role of medical ethics in hospital administration and medical treatment behaviors.It is an urgent ethical requirement and the chief task for hospital administrators to achieve humanistic medical service through humanistic administration of hospitals.

Objective To investigate the influence of indomethacin to the unite treatment effect on chronic phase myeloid leukemia (CML-CP) with interferon alpha-2b (IFNα-2b) and low dose cytarabine (LD-Ara-C).Methods 22 CML-CP patients were randomly divided into two groups.Control groups (10 cases) injected with IFNα-2b (3 million units),injection frequency was q.o.d,the duration of treatment was about 3-18 months,cytarabine (Ara-C) by slowly intravenous driped (30 mg/d).In this treatment schedule,every course of treatment sustained 10 days,and with a 2 weeks interval.During this process,patients in treatment group were treated with hydroxyl urea only when their WBC in peripheral blood exceed 20×109/L,otherwise,discontinue it.Treatment group (12 cases),on the first day of treatment with IFNα-2b and Ara-C,added indomethacin (25 mg) through oral administration,the frequency was t.i.d.During treatment in the two group,the end point of observation was completely hematology ease,at the same time,these indicators in the two groups needed to be compared,the time when WBC begin to fall,the time when WBC fall to normal range,the time when immature cells returned to normal,the time which complete hematological remission and the highest temperature of patients after IFNα-2b was subcutaneous injected.Results The time when WBC begin to fall in treatment group was (4.2±2.7) d,and the time was (5.0±2.5) d in control group (t =0.714,P ＞ 0.05).In treatment group,the time when WBC fall to normal range was(10.0±4.5) d,and the time was (12.0±4.5) d in control group (t =1.036,P ＞ 0.05).The time when immature cells returned to normal in treatment group was (14.2±4.8) d,and the time was (19.0±3.6) d in control group (t =2.609,P ＜ 0.02).The time which complete hematological remission was achieved in control group was (45.8±5.6) d,but it was (53.9±10.5) d in control group (t =2.314,· P ＜ 0.05).Meanwhile,the fever degree after IFNα-2b was subcutaneous injected obviously achieved improvement in treatment group (x2 =12.041,P ＜ 0.005).Conclusion The advantage of indomethacin to the unite treatment with IFNα-2b and LD-Ara-C on CML mainly lays in which cound alleviated the adverse reaction such as flu-like of IFN,and more,there are synergy effect in antagonist CML.

Objective To study on the factors of sheep plasma method detect heparin potency and improved methods.Methods Acorrding to sheep plasma method, to study the bubbles, solids, pH and NaCl concentration on the heparin potency determination.Results The bubbles impact on the heparin potency determination was less.Solids were the main factors on heparin potency determination, containing solids protein hydrolysates heparin potency determination was (2.87 ± 0.01 ) U/mL, after removing solids potency was 24.60 U/mL, raised about 8.5 times.In the removed solids sample, when pH 7.5 to 9.5 had little effect on heparin potency determination, and pH 6.5 and 7.0 had smaller effect on the heparin potency determination.The presence of solids in the sample, as the sample pH rised, heparin potency determination also rised, at potency of sample at pH 9.0 was 3.4 times than that at pH 6.5.Enzymatic hydrolyzate mainly contain: 47.86% protein, 39.16% NaCl, 4.12% fat, wherein the protein was 91.34% of small peptides.NaCl concentration had no effect on the heparin potency determination.The improved method of recovery assay value was 98.92%~101.53%.Conclusion The method is reliable, the heparin output value calculated by measuring value in accordance with the process of practical production output.This method can be used for the determination the production process of each link in heparin potency of heparin.

Objective To observe the estrogenic activity of octylphenol(OP) in vitro and to conduct a preliminary study of its mechanism. Methods The estrogenic activity of OP was detected by cell proliferation test of MCF 7 cells in vitro and the mechanism was preliminarily studied by growth curve analysis, cell cycle analysis, tamoxifen(Tam) antagonistic test and apoptosis detection. Results OP was found to have estrogenic activity to stimulate the proliferation of MCF 7 cells. Cell cycle analysis revealed that the cell proliferation indexes of OP and 17? estradiol(E 2) were higher than those of alcohol. The estrogenic activities of OP and E 2 to stimulate the proliferation of MCR 7 could be antagonized by Tam. Both OP and E 2 could inhibit the cell apoptosis of MCF 7 cells. Conclusion OP possesses estrogenic activity to stimulate the proliferation of MCF 7 cells. The mechanism may be due to binding to the estrogen receptor, which may have effect on cell proliferation and apoptosis.
