Results 1 there were no significant differences of amplitude of accommodation and accommodative lag between the myopia group and emmetropia group. The differences of amplitude of accommodation between the myopia group and hyperopia group were significant (t=2.21, P=0.03.05; t=2.83, P=0.006.05). 2 The difference of accommodative lag between the dominant eye (0.73±0.31) D and non-dominant eyes (0.81±0.38) D in myopia group was signiflcant.3 The accommodative lag of dominant eyes was (0.68±0.36) D and it of non-dominant eyes was (0.75±0.34) D, the difference was significant (t=2.06, P=0.042.05, n=95).There was no significant difference between the amplitude of accommodation of dominant eye (12.9±3.09) D and non-dominant eyes (12.6±3.09) D.

Isolation, purification and characteristics of D-hydantoinase were carried out. The experiment results showed that the optimal pH and temperature of pure D-hydantoinase were pH 8. 5 and 35℃, respectively. D-hydantoinase activity could be increased significantly by Mn〓 and Fe〓. Substrate specificity of D-hydantoinase on various hydantoin derivatives showed the optimal substrate of D-hydantoinase was 5-phenylhydantoin, but hydantoin, 5-methylthioehylhydantoin, 5-hydroxyphenylhydantoin, 5-methylhydantoin, 5-benzylhydantoin could also be hydrolyzed by D-hydantoinase.

After amputation, the expression of desmin appears first in the distal end epidermis and the peritoneum 4 d PA. The expression in the peritoneum lasts to the 14 d PA when expression of desmin appears in the musculature, while that in the distal end epidermis only lasts to the 8 d PA when the connective tissue below begins to express desmin. Moreover, from the 4 d PA, musculature and epidermis of the tube foot begin to express desmin and the expressions last to the 20 d PA. From 8-14 d PA, musculature of the ambulacral plate expresses myogenin and the peritoneum also expresses myogenin from 14-20 d PA. All these results indicate that precursor cells for muscle regeneration in adult starfish A.rollestoni are mainly from the distal end epidermis and the parietal peritoneum.

For assisting identification of crude drug Herba Dendrobii. Methods Morphological and histological studies were carried out on 11 medicinal plant roots in Dendrobium Sw. by microstructural observation. The 11 species were divided into three groups according to their stem morphology: a pair fleshy-stem group, including D. chrysanthum, D. crepidatum, D. primulinum, D. hercoglossum, and D. crystallium; b thick-and rigid-stem group, including D. fimbriatum and D. aurantiacum var. denneanum; c node-or inter- node- bulgy-stem group, including D. findlayanum, D. gratiosissimum, D. pendulum, and D. wardianum.

Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4
