Each embryo were inoculated by a dose of 1×104 pure sporozoites was injected with testing Bt crystal proteins before 24 hours. The varying oocyst inhibition rates of embryos brought about by Bt crystal proteins that were given at various doses were used as a criterion for determining the activity of Bt crystal proteins.

The researchs on isozymes indicated that some varieties of isozyme loci present during the embryo development. There are 7 esterase loci and 5 acid phosphatase loci during the periods between nucellar filament and early globular embryo; both of Est and Acp appeared the most diversity in the stage of 8-nucleate embryo sac.

用聚丙烯酰胺凝胶电泳的方法研究鹤顶兰从指状突起出现到早期球形胚形成的全过程中酯酶、酸性磷酸酶的变化发现：这一过程中酯酶表达有7个同工酶位点，酸性磷酸酶有5个同工酶位点，两者均在八核胚囊时期变化最显著。

From its the depart in splanchnic organization arrives bacterium of 2 individual plant, pass bacteriological method appraisal, one individual plant is deputy pig bloodsucking bacili, another individual plant is a pig streptococcic; will send check sample book have an inoculation to marc-145 cell, can observe cellular pathological changes, the pcr of virus fluid classics of results detects, for positive of blue ear ill viru

从其内脏组织中分离到2株细菌，通过细菌学方法鉴定，一株为副猪嗜血杆菌，另一株为猪链球菌；将送检样本接种到marc-145细胞，能观察到细胞病变，收获的病毒液经pcr检测，为蓝耳病病毒阳性；将送检的样本接种spf鸡胚，收获的鸡胚尿囊液有血凝性，血凝试验和血凝抑制试验鉴定为猪副黏病毒。

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。

The result showed that the isolation of embryosac was carried out with fresh ovules,which were macerated in two designed mixture solution.

实验了7种多种酶组合的混合酶液，其中以配方3和配方4效果较好，3-4小时内，可以从新鲜的泡桐胚珠中将胚囊酶离出来。

The histological observation showed that the larvae of S .japonicum in superinfected snails were sluggish in development, irregular, shrunken, deformed, relatively small in number as compared with the control. The sporocysts contained few germ balls or immature cercariae and most of the digestive glands of superinfected snails were atrophiej.
