Results:Main imaging features of APK were as follows:On abdominal plain films showed the lobalate renal enlargement in 46 cases,calcification of polycystic wall in 14 cases,renal calcium milk in 5 cases,60 cases were showed separation,deform and longthend of renal pelvis on intravenous urography and retrograde urography,5 cases were showed renal enlargement on retroperitoneal pneumography,on CT scans in 25 cases showed mulltiply cysts with thin wall,unecho liquid shadows were showed on B-mode ultrasound.

结果：成人多囊肾的主要影像学征象：腹部平片(46例)显示肾影呈分叶状增大；囊壁钙化(14例)；多囊肾合并肾钙乳(5例)；肾盂造影(60例)，表现为肾盂、肾盏相互分离、变形、拉长；腹膜后充气造影(5例)：表现为肾影增大肾影与邻近器官之间的关系，其界限清晰可辨；CT扫描(25例)：表现为肾内多数大小不等的薄壁圆形低密度区；B型超声(47例)表现为肾内多个类圆形无回声的液性暗区。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。

The osteoid osteoma was found to have a circular or oval radiolucency which was less than 2 cm in diameter with different degrees of bone sclerosis around the nidus. Of the 9 cases, 5 showed an irregular area with less density on plain X-ray film. CT scanning showed nidus in all cases. MRI showed nidus in 1 case. Radioactive scanning showed radioactive concentration in 4 cases.

骨样骨瘤的影像学表现为一圆形或卵圆形的透亮区，直径cm，其周围有不同程度的骨质硬化。9例X线平片仅5例发现不规则密度减低区，9例CT均清楚显示病灶瘤巢； 1例MRI也观察到类似瘤巢的改变。4例同位素检查均表现为病变区核素浓聚现象。

Results the imaging manifestations of osteoid osteoma revealed a circular or oval radiolucency with different bone sclerosis around the nidus.the diameter ranged from 0.3cm to 1.6cm,with the average of 0.9cm.among 18 cases,only 14 cases showed nidus on plain film, all 15 cases with ct scanning showed nidus.the detection rate of nidus was 78％(14/18) for x-ray plain film and 100％(15/15) for ct, respectively.

结果 18例病灶均表现为一圆形或卵圆形的透亮区，直径0.3～1.6cm，平均0.9cm，其周围有不同程度的骨质硬化。18例x线平片仅14例显示瘤巢，15例行ct检查者均清楚显示瘤巢，x线和ct对瘤巢显示率分别为78％(14∕18)和100％(15∕15)。

All lesions were 7-12 mm in greatest diameter. Seven cases showed a round radiolucency or a thin clear sclerotic rim in middle or up-outer of femoral neck on X-ray film.

结果：8例股骨颈疝窝均为单侧单发病灶，X线平片仅显示7例，CT均表现为股骨颈前方皮质下类圆形骨质缺损，内为较均匀液体密度，边缘清楚伴有硬化缘，最大径线为7-12 mm.7例在X线平片上表现为股骨颈中轴线或其外上方的类圆形透亮区或硬化环。

Using GSA-〓 lectin histochemistry, the first appearance of microglia occurred at E13, usually stained as scattered amoeboid cells. From then on, the number of microglia increased steadily, reached a peak at postnatal day 7 (P7), and then reduced gradually to adult level. Generally the morphological form of microglia undergoes transformation from early rounded or ameboid to adult resting ramified as they differentiate during development.

使用凝集素GSA-〓亲和组织化学染色，本实验最早观察到小胶质细胞在胚胎13天（E13），为散在分布的圆形或阿米巴样细胞，随后细胞数量逐渐增多；总体而言小胶质细胞的形态遵循着由圆形或阿米巴样逐渐转向纤细分枝状的演变规律，不同阶段细胞形态各有其特点，在不同区域也存在差异；小胶质细胞的数量在生后第七天（P7）达到高峰，其后开始逐步降低直至成年。
