The results of study show:1. White pulp and red pulp in parenchyma of spleen of embryo can be obviously discerned after 18 days. Periarterial lymphoid sheath and ellipsoid periarterial lymphoid sheath also can be obviously discerned in spleen of 4 days chicken. T, B lymphocytes in appendix basement of embryo emerge after 20 days. It is the initial shape of cecal tonsil. Crypt structure of conjunction of esophago and stomachus glandularis form obviously at 4 days. It is the initial shape of esophago tonsil. The germinal center firstly emerges in these three organs at 14 days. With the increase of day age, the characteristic structure peripheral immune organs gradually develop mature. Spleen achieve mature at 21 days and cecal tonsil at 35 days.2. IgM~+ and IgA~+ cells in spleen of embryo emerge at 15 days. IgG~+ cell, CD3~+ and CD8~+T lymphocytes of embryo emerge at 20 days. CD3~+, CD8~+ and IgM~+ cells in cecal tonsil of embryo emerge at 20 days. However CD4~+, IgG~+ and IgA~+ cells all emerge in 1 day age chicken out of crust. CD3~+, CD4~+, CD8~+, IgM~+ and IgG~+ cells in esophago tonsil of embryo all emerge at 20 days. However IgA~+ cells emerge in 1 day age chicken out of crust.3. The amount of T, B lymphocytes in peripheral immune organs increase follow with the increase of day age, and hold an upgrade tendency. The amount of T, B lymphocytes in spleen achieved stabilization at 21 days, and in tonsil of esophago and appendix at 35 days.

研究结果表明：1、在组织结构方面，脾脏实质内的白髓与红髓在胚胎18日龄后明显可辨，4日龄雏鸡脾脏中形成明显可辨的动脉周围淋巴鞘和椭球周围淋巴鞘；盲肠基部T、B淋巴细胞在胚胎20日龄时开始出现，即初步形成盲肠扁桃体；食管与腺胃结合处在4日龄时形成明显的隐窝结构，即食管扁桃体初步形成；14日龄时，三种器官中首次出现生发中心；随着日龄的增长，外周免疫器官特征结构不断发育成熟，脾脏在21日龄时达到成熟水平，盲肠扁桃体和食管扁桃体在35日龄时达到成熟水平。2、在T、B淋巴细胞出现时间方面，脾脏中IgM~+和IgA~+细胞在胚胎15日龄时开始出现，IgG~+细胞、CD3~+和CD8~+T淋巴细胞在胚胎18日龄时出现，CD4~+细胞在胚胎20日龄时出现；盲肠扁桃体中CD3~+、CD8~+和IgM~+细胞在胚胎20日龄时开始出现，而CD4~+、IgG~+和IgA~+细胞均在雏鸡出壳后1日龄时出现；食管扁桃体中CD3~+、CD4~+、CD8~+、IgM~+和IgG~+细胞均在胚胎20日龄时开始出现，而IgA~+细胞则在雏鸡出壳后1日龄时出现。3、在T、B淋巴细胞数量变化方面，外周免疫器官中T、B淋巴细胞的数量随日龄增长，整体均呈上升趋势。

objective to study the changes of t-pa and t-pa inhibitorduring the acute stage of cor pulmonale.methods to measure the plasmatic activity of t-pa and pai by chrom-substrate in60cases of cor pulmonale,compared with the corresponding index of55cases in the control group.results pai was significantly higher in acute stage than in remission stage of corpulmonale,and t-pa was lower in remission stage than in acute stage.the difference was significant（p.01）.conclusion the unbalance between t-pa and pai can promote the formation of micro-thrombus and further exacerbate high pulmonary pressure.

目的 探讨血浆组织型纤溶酶原激活物及t-pa抑制物在肺心病急性加重期的变化。方法用发色底物法测定60例肺心病急性加重期的血浆t-pa及pai的活性，并与对照组55例肺心病缓解期的相应指标作比较。结果肺心病急性加重期患者pai显著高于肺心病缓解期，而t-pa低于肺心病缓解期，其差异具有非常显著性（p.01）。结论 t-pa及pai关系失衡，有助于动脉内微血栓形成，促进或加重肺动脉高压的形成。

Results In 9 cases of endometrial biopsy of materials by uterine curettage, the cells of endometrial stromal sarcomas of 6 cases were well differentiated and like stromal cells of endometrial hyperplasia; the cells of endometrial stromal sarcomas of 3 cases were poor differentiated, the cells of 2 were like that of malignant lymphoma, and another like that of pleomorphous sarcoma. In 9 cases were found the distribution of vessels cluster like endometrial corkscrew small artery. The tumor cells were grew along lymphatic or protruded in lymphatic, and there were small islands or small pieces of tumor cells in the interspace of muscles in 2 cases. The contrastive observation of the specimens of resected uterines of 9 cases confirmed the valve of above features to the confessed diagnosis of endometrial stromal sarcomas in the materials of endometrial biopsy or uterine curettage.

The pleural superficial, subpleural and parenchymal vacular networks were denser, and the range of the microvessels in diameter were larger, and the proceeding distance of the subpleural arteriole and its branches were longer in the adult yak lung than those in the adult cattle lung. However, the anastomosing between the pleural superficial and the subpleural vascular networks were more often found in the adult cattle lung than that in the adult yak.

All afferent and efferent vessels were measured and recorded. Results Anterior scrotal artery coming from superficial external pudendal arteries is divided into medial and lateral branches at lateral penile base and spread out on lateral and anterior surface of scrotum. Diameter of internal branches are(0.54±0.34)mm and (0.69±0.09)mm. Lateral scrotal artery(100%present rate, 0.62±0.19mm in diameter)originating from obturator artery distributes to lateral side of scrotum.Posterior scrotal artery is separated into lateral branches and septal scrotal artery at posterior scrotal ploe. The former(0.8±0.1mm in diameter)spreads to lateral and posterior region of scrotum.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
