查询词典 D

If a child in the spring to provide food less calcium, and vitamin D were more children blood to the bone calcium deposition, caused by the concentration of calcium in the blood decreased, resulting in children tetany, which is usually referred to "ventilation" or "cramp", which also can be found in taking more vitamin D and calcium intake fewer children.

如果在春天给孩子提供含钙的食品较少，而维生素D较多时，孩子血中的钙会向骨骼沉积，而引起血液中钙的浓度下降，从而导致孩子手足搐搦，也就是通常所说的"抽风"或"抽筋"，这种情况也可见于服用较多的维生素D而钙摄入较少的孩子。

Objective To investigate the curative effect of left ventricular hypertrophy with uretic indapamide, Methods 96 patients wiht LVH were divided into two groups, 50 patients in A group were treated with indapamide 2,5～5mg/d, and 46 patients in B group with nifedipine 20～60mg/d for 12 months, Results Blood pressure、interventricular septum thickness、left ventricular posterior wall thickness、left ventricular mass index and left ventricular ejection fraction in all cases were improved after treatment, A group was better than B in LVEF, Conclusion Both indapamide and nifedipine can regress LVH, and improve left heart function

目的 观察新型噻嗪类利尿剂吲达帕胺逆转左心室肥厚的效果。方法 96例高血压LVH患者，分别给予吲达帕胺(A组，50例)2，5～5mg/d和硝苯地平控释片(B 组，46例)20～60mg/d持续12个月治疗，观察治疗前后血压及左室结构变化。结果两组治疗前后血压、室间隔厚度、左心室后壁厚度、心室重量指数和左心室射血分数均有改善(P＜0，05～0，01)，A组在改善LVEF方面优于B组(P＜0，05)。结论吲达帕胺具有与硝苯地平类似的逆转LVH作用，有明显改善左心功能作用。

Methods The otoconia of 18 guinea pigs were damaged by a high G force (10 Gy 5 min), and their utricle macula were observed by scanning electron microscopy at 1 h, 2 d and 8 d after the damage respectively. The elements of different kinds of otoconia were measured qualitatively and quantitatively by electron probe Xray microanalysis.

给予过载刺激(10 Gy 5 min)造成18只豚鼠耳石的损伤破坏，用扫描电镜（scanning electron microscopy，SEM）分别观察过载刺激后1 h、2 d、8 d时其椭圆囊囊斑，用X射线显微能谱分析技术(electron probe Xray microanalysis，EPMA)测量不同形态类别的耳石元素构成。
