The ultraviolet spectrophotometric method for determination of vitamin A in breast milk was simplified. The milk sample was extracted directly with ammonia water, ethyl alcohol and ether, the saponification procedure be- ing omitted. The optimal height of the aluminum oxide adsorption column and the optimal rate of flow for elution were developed. The observation was made whether the elution for vitamen A was complete by identifying the fluorescence of vitamin A directly under ultraviolet light in the eluat-es collected instead of SbCl3-Vitamin A blue color reaction. The simultaneous estimation of Vitamin A in breast milk and in the standard solution of Vitamin A with this method showed E300nm/E325nm less than 73%, agreeable with the British Pharmacopoeia. The recovery was 100.8%. This procedure has advantages of high sensitivity, simplicity, time saving and economy.

Objective To observe the difference in therapeutic efficacy between acupuncture with distant acupoints selection and proximal acupoints selection in treating acute headache.Method Sixty patients with acute headache were randomized into group A and group B, 30 cases in each group. Group A was intervened by acupuncture with distant acupoints selection, while group B was by acupoints with topical acupoints selection. The Visual Analogue Scale (VAS) and Present Pain Intensity (PPI) from McGill Pain Questionnaire (MPQ) were observed before and after intervention, and the clinical efficacies were compared between the two groups. Result After treatment, the VAS and PPI scores were significantly different from that before treatment in both groups (P<0.01). The changes of VAS and PPI scores in group A after intervention were significantly different from that in group B (P<0.01). The total effective rate was 90.0% in group A versus 73.3% in group B, and the difference was statistically significant (P<0.01). Conclusion Acupuncture with distant acupoints selection can produce a better therapeutic efficacy than acupuncture with topical acupoints selection.

Objective To determine the prevalence of vulvovaginal candidiasis(VVC) in pregnant women,to test its antifungal susceptibility to miconazole,clotrimazole,fluconazole, itrocona- zole,and nystatin and to treat VVC with miconazole in pregnancy. Methods Vaginal swabs were collected from unselected pregnant women in prenatal clinic. The antifungal susceptibility of 131 strains of Candidas to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin were detected by Neo-Sensitabs susceptibility testing. 66 cases of VVC were treated with 6 day-course of miconazole(400 mg/d). Results The prevalence of VVC in pregnant women was 12.7%(127/1000). 37.4%(374/1000) had previous VVC. 0.6%(6/1000)of women were recurrent VVC(RVVC),which occupied 4.7%(6/127) of VVC. C. albicans was the most frequently(87.1%) isolated pathogen followed by C. glabrata (9.9%) ,C. tropicalis(1.5%),and C. krsei(1.5%). The resistant rate of C. albicans to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin was 10.5%、2.6%、 6.1%、 7.9%,and 0. All 13 strains of C. glabrata was susceptible to miconazole,nystatin and susceptible or susceptible-dependent-upon-dose (SDD) to clotrimazole,fluconazole,and itroconazole. The mycological cure rate of miconazole on day 7～14 and day 28～42 was 84.8%(56/66 cases) and 80.3% (53/66 cases). Conclusions VVC is very common in pregnancy. C. albicans is the predominant Candida species in VVC and has some resistance to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin. Miconazole therapy is effective on VVC treatment in pregnant women. Non-effective treatment might be associated with Candidas resistance.

Twenty-four novel benzothiazole derivatives containing arylpiperazine were designed and synthesized by bioisosterism principle. Anti-proliferative effect of these synthesized compounds against four cancer cell and two normal cell lines were evaluated in vitro by the standard MTT assay. Pharmacological test showed that most of the compounds exhibited potent antitumor activity. Some of the compounds (II2, II3, II6, II7) showed strong anti-proliferation activities against HepG2 and HeLa229 cell lines with the IC 50 values of 1.6-4.5 micromol x L(-1) and 2.5-5.3 micromol x L(-1), respectively, and compounds having cyan in p-substituted benzene ring (I4, I8, I12, II4, II8 and II12) were found to have better antitumor activities against AsPC-1 cell lines with the IC50 values of 5.2-11.3 micromol x L(-1). The structure-activity relationship of benzothiazole derivatives containing arylpiperazine was also discussed preliminarily.
