Objective The purpose of this study was to edit and psychometrically equate a set of Mandarin bisyllabic word lists. Methods 964 bisyllabjc words were recorded by male talker of standard Mandarin,352 words were selected to compose 10 lists. Percentage of correct word recognition was measured for each word at four intensity levels using 20 normal hearing subjects. The order of the presentation of the lists was randomized for each subject. U-sing Statistica7.0 Performance-Intensity function for each word was plotted,slopes and thresholds of them were calculated. 242 words were chosen after that, The thresholds and slopes of these words were in Guassian distribution. These words were ligitally adjusted and included in six Mandarin bisyllabic word lists of 40 words each. Two of them were for practice, four of them for test. 36 subjects with normal hearing served in our equivalent test. The orders of the presentation of the lists were randomized far each subject and results were expressed as thresholds. Results Two-factor ANO-VA was used to compare the thresholds of the 4 lists, F=1.978,P = 0.209. Conclusion These lists were considered to be primarily equivalent with each other.

Objective: To evaluate the pharmacodynamic of clematis. Methods: 1) The relaxation of isolated ileum muscle of guinea pig by clematic was tested. The antagonism of clematis on histamine or Ach induced ileum muscle contraction was tested also. 2) By using the model of turning of trunk, the pain releasing effect of clematis was evaluated. 3) The experiments about anti-inflammation action of clematis were carried out in two models. Results: Clematis relaxed the ileum muscle. It also antagonized the contraction of the muscle caused by histamine and Ach. A single intrapeditional administration of clematis to Kun-Ming mice significantly prolonged the latency and reduced the writhe number at the turning of trunk model; clematis dose-dependently inhibited the mouse ear swelling caused by xylol. It also had anti-inflammation effect at the other model. The results demonstrated that clematis could release the pain, suppress the inflammation and smooth muscle contraction.

BACKGROUND:As the pharmacological effect of eugenol constantly being discovered, its application in medical and food industry becomes wider. However, its toxicity studies have not established a complete database, especialy in the improvement of safety assessment of developmental toxicity and teratogenicity. OBJECTIVE:To establish a model of embryonic stem cel test to evaluate the embryotoxicity of eugenol. METHODS:Mouse fibroblasts (3T3) and mouse embryonic stem cels (E14TG2a) were culturedin vitro, and MTT test was performed to detect the cytotoxicity of 3T3 cels and E14TG2a cels with positive control 5-fluorouracil, negative control penicilin G and tested compound eugenol. The concentration of the tested compounds that inhibiting 50% viability of embryonic stem cels (IC50 E14TG2a) and 3T3 fibroblasts (IC50 3T3) was calculated. The hanging-suspension-adherent culture systems were used to induce embryonic stem cels into cardiomyocytes, and the concentration of tested compounds that caused 50% inhibition of differentiation of E14TG2a cels into cardiomyocytes (ID50 E14TG2a) was calculated. The embryotoxic potential of eugenol was classified by prediction model of the embryonic stem cel test. RESULTS AND CONCLUSION:The proliferations of E14TG2a and 3T3 cels were inhibited by eugenol, of which the IC50 3T3 and IC50 E14TG2a values were (3.613±0.192) and (1.799±0.131) mg/L. The differentiation of E14TG2a was also inhibited by eugenol, of which the ID50 E14TG2a was (3.501±0.158) mg/L. Eugenol was evaluated as a chemical compound with strong embryotoxicity by the model of embryonic stem cel test.
