The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.

结合触角电位、毛细管气相色谱、扫描电镜、透视电镜等技术对小线角木蠹蛾雌蛾腹尖末端不同组织部位提取物的测定分析以及腺体位置和形态结构的观察发现：小线角木蠹蛾性信息素分泌腺位于腹部末端8～9节之间，是一个由节间膜特化而成的上皮结构，为一可外翻的腹褶，腺体表面分布着饱满的锥形体，羽化后2天未交尾的雌蛾腺体细胞呈单层排列，腹面中央由密集的柱形上皮细胞组成，细胞排列向两侧延伸至背部，其形状由柱形逐渐变为扁平形，细胞核为椭圆形，细胞与细胞间有明显的胞连接，细胞基底膜基褶较多，质膜上分布着微绒毛，并与内表皮连接，内表皮上有多层几丁质，外角质层染色较深，细胞质中含有空泡、线粒体、脂质粒、粗面内质网和光面内质网。

Theurinary IL-6 level positively correlated with density of glomerular matrix membrane, global sclerosis, fiber or fibrocellular crescents and interstitial fibrosis (p. 05). According to the degree of density of glomerular matrix membrane and interstitial fibrosis, urinary Col-IV level had better correlation than urinary TGF-betal and IL-6 levels.In IgAN, Col-IV showed increased expression in diseased renal tissue whereas the site of expression of TGF-betal was mainly localized within the cytoplasm of tubular epithelial cells. Interstial expressionwas also present but glomerular TGF-betal expression was found only in patients with heavy mesangial proliferation. There was a significant correlation between glomerular positivity for Col-IV and severity of histological damage. There was also a significant correlation between positivity for TGF-betal and Col-IV in the tubular epithelial and interstitial lesions. In contrast, there was no ralationship between glomerular positivity for TGF-betal and severity of histological damage.The urinary TGF-betal level paralleled tubular TGF-betal expression.

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

The results showed that:(1) In COPD group the alveolar walls were broken. The average area of alveolars was 2.46 times as big as the control group, and the average diameter was 1.42 times as compared with the control group. As the diameter of bronchioles was less than 100μm and 100～200μm respectively, the average area of smooth muscle in bronchioles increased to 3.06-fold and 2.13-fold respectively. By electron microscopic, the proportion of Clara cells of respiratory bronchioles in COPD group decreased, the Clara cells were denaturalized, the proportion of Clara cells containing low density secretory granules increased. The airway resistance was 1.84 times while the dynamic compliance was only 70.45% comparing with the control group.

结果表明：(1)光镜下，COPD组大鼠与正常对照组比较，肺泡壁破坏、肺泡腔扩大，平均肺泡面积和平均肺泡直径分别为正常对照组的2.46倍和1.42倍，在直径＜100μm及直径100～200μm的小支气管，COPD组大鼠支气管平滑肌面积分别为正常对照组的3.06倍和2.13倍；电镜下可见，在呼吸性细支气管，Clara细胞占上皮细胞的比例下降，细胞变性，含低电子密度颗粒的Clara细胞比例增加；呼吸功能测定可见COPD组大鼠呼气相气道阻力是正常对照组的1.84倍、动态呼吸系统总顺应性为正常对照组的70.45％。

The proliferative capacity of LEC from human had directly relevance to the age of donor(r=-0.996).Conclusions The formation of lens-like spherules is characteristics of LEC lines in the cultured cells.Under identical conditions,the proliferative rate of LEC from bovine and rabbit is fast than that of LEC from human,but dedifferentiation of LEC from bovine and rabbit is easier than that of LEC from human;LEC from the three species exhibit similar limited growth potential.The proliferative rate of LEC from human has a inversely proportion with age.
