The expressions of retinoic acid receptors in intestinal mucosa were positive correlated with VA states,and which was likely to involve into the regulation of VA on mucosal immunity.

肠粘膜视黄酸受体的表达不仅与VA营养状态呈正相关变化,而且可能还参与介导VA对粘膜抗感染免疫的调节作用。

Methods: Retinoic acid(RA)was used to made mouse systemic osteopenia model.

方法:应用药物维A酸制作小鼠骨质快速丧失模型。

In our previous study, a series of new gene fragments was obtained by using PCR-based subtractive hybridization technique to screen cell differentiation and apoptosis-related genes from retinoic acid-treated promyelocytic cell line HL-60 cells.

利用“基于PCR的减法杂交技术”研究了维甲酸诱导早幼粒白血病细胞分化和凋亡时所表达的特异基因，得到了一系列新基因克隆片段。

The effect of the combined use of retinoic acid and sodium selenite was closed to the sum of that of retinoic acid and sodium selenite used separately.

视黄酸和亚硒酸钠同时处理的联合组作用强度接近于两者单独使用时作用强度的加和。

Third, Retinoic acid was modified by use of sugar, and hydroquinone as bridge. A mild selective method for deacetylation has been developed.

第三、以异维A酸为母体,对苯二酚为桥联,采用相转移催化法合成了糖苷。
