Mitochondrial gene fragments of COⅠ and Cyt b of 24 species in the subfamily Pierinae and Coliadinae were amplified and sequenced. Combing these with the homologous sequences of 2 species from GenBank and using 2 species of the Satyridae as the outgroups, the molecular phylogenetic trees of these groups were reconstructed with neighbor-joining and bayesian inference methods.

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

褐色脂肪组织是小哺乳动物非颤抖性产热的主要器官，该组织具有一个独特的非偶联呼吸机制，它是由细胞线粒体内膜上的解偶联蛋白所决定的。

In order to analyse the relationship between several Trichinella isolates from different areas in China,we amplified the COI gene from these isolates and obtained their sequences.

为了了解我国几个不同地区旋毛虫之间的种属关系，我们对这些地区的旋毛虫进行了线粒体细胞色素氧化酶亚单位I基因的扩增，并得到了正确的COI基因。

The cytochemical localization of POD showed that the peroxidase was found in cells ofboth cultivars after inoculation. The activity of POD in resistant cultivar was higher than that innot only the uninoculated controls but also the inoculated susceptible ones and localized morewidely, such as localized in mesophyll cell wall, intercellular spaces, membranes of chloroplastand mitochondrion and vacuolar membrane. Whereas the POD in susceptible cultivar waslocalized mainly in cell walls but little in plasma membrane with a lower range and intensitythan that in resistant cultivar.

对过氧化物酶的细胞定位研究发现，无论抗病杨树还是感病杨树，接种后均发现细胞中有过氧化物酶反应产物，通过分析发现，毛白杨过氧化物酶的活性不仅明显高于未接种的对照，也明显高于接种处理后的北京杨，并且定位更广泛，在细胞壁、细胞间隙、叶绿体膜、线粒体膜及液泡膜上均有大量定位，而北京杨酶反应产物主要分布于细胞壁上，在细胞膜、核膜局部有少量定位，定位范围及强度均小于毛白杨。

The findings of the newly identified goose paramyxovirus strain GPMV/HBexperimental infection were as follows: The challenge caused high morbidity and highmortality.The clinical signs included severe depression, decreased appetite or anorexia,white,yellow and green diarrhea, with neural symptoms;pathological changes showed thathaemorrhage and ulceration of intestine mucosa, necrosis of spleen and pancreas,andedema of liver and kidney, uratic deposition in kidney.Eosinophilic inclusion bodies werefound in the cytoplasm of pancreas and a large quantities of fiber protein were found inintestine. Lots of hemosidefin was found in some area of liver and kidney. A number ofT、B lymphocytes reduced sharply in spleen,lymph nodes in dead geese. Transmissionalelectron microscope showed that some cells had the morphological characteristics ofmitochondria swelling, morphological changes were condensation of nuclear chromatininto dense masses,followed by its marginating against the nuclear envelope, andespecially concentration of cytoplasm association with lots of lipid droplet.

人工感染雏鹅实验中，雏鹅临床表现为高发病率和高死亡率，食欲和饮水减少，拉白色、黄绿色稀粪，伴有神经症状；常规组织学观察，脾脏和胰腺肿大，有白色坏死斑点，肠道出血和坏死，肝脏肿大变性，肾脏肿大变性有尿酸盐沉着等；用特殊染色和组织化学方法首次对人工感染鹅副粘病毒的雏鹅的重要脏器进行研究，结果表明：胰腺中发现病毒包涵体，肠道中大量纤维素以及胶原纤维增生，肾脏、肺脏大量含铁血黄素沉着，免疫器官如脾脏和淋巴结中T、B淋巴细胞大量减少；电镜下多种细胞呈现线粒体水肿，多种实质细胞的染色质固缩，染色质边集，特别是细胞内容物如脂肪滴增多的病理变化特征。

Confocal microscope detection experiments showed that, in morulae and blastocysts, with theincreasing concentration of BPA, embryo of cytochrome C release rate increased. This showedthat the cytochrome C involved in BPA-induced the embryos apoptosis process. This processis regulated by the mitochondrial pathway.

激光共聚焦显微镜检测细胞色素C结果显示：在桑椹胚期和囊胚期，随着BPA处理浓度的升高，释放细胞色素C的胚胎比率逐渐增加，说明细胞色素C参与了BPA诱导胚胎细胞凋亡的过程，这一过程是通过线粒体通路来调节的。
