For tumors which have been well sampled and exhibit (1) a microcystic pattern and regions with lobulated cellular masses with intervening, sometimes hyalinized fibrous stroma,(2) an absence of morphologic features enabling any other specific diagnosis in the sex cord-stromal category,(3) an absence of epithelial elements, and (4) an absence of teratomatous or other germ cell elements, we propose the designation microcystic stromal tumor.
我们很好地抽样调查了4例肿瘤,显示:(1)微囊样式和有时插入玻璃样变的纤维间质中的分叶状细胞团区,(2)能造成在性索间质这个大类中其他具体诊断的形态特征缺失,(3)上皮成分缺失,(4)畸胎或其他胚芽细胞成分缺失,我们提议定其名为微囊性间质瘤。

With the Sand culture method, influences of different magnesium levels (0%、50%、100%、150%、200% and 300%) was explored to the wheat seedlings of different stages. Many targets such as plant height, root length, biomass, content of chlorophyll, activity of root, RGY, RGR and ratio of root to crown of the wheat were mensurated at the time of 7d, 15d and 30d of two leaves stage of wheat seedlings after their endosperms were removed at different magnesium levels.The results showed that different magnesium levels had unlike influences over the wheat seedlings.
