保安湖鳜鱼脑垂体周年变化的组织学观察

对性成熟雌性鳜鱼的脑垂体进行了组织学研究。鳜鱼脑垂体由神经垂体和腺垂体两大部分组成。腺垂体分为前叶，间叶和过渡叶。间叶中含有嗜酸性细胞，嗜碱性细胞和嫌色细胞。其中嗜碱性细胞的形态和数量在年周期中有明显变化，并与生殖活动密切相关。     

中华绒螯蟹性腺发育的形态学、组织学和组织化学变化

以组织学、组织化学方法研究了中华绒螯蟹后期的性别分化过程。结果表明，中华绒螯蟹雌雄个体在此过程中形态学变化差异显著，雌蟹最宽腹节由第一节逐渐向第五节转变，雄蟹则始终为第三节；雄蟹最长腹节长与背甲长的比率随背甲的增大而减小，而雌蟹则相反，其形态上的差异可作为区分幼蟹性别的直观依据。卵巢从发生到成熟，其颜色由透明、白色、浅咖啡色、豆沙色至深豆沙色转变；精巢的发生则早于卵巢，当卵巢仅为原始生殖细胞团时，精巢已初步具有完整的形态，并且精子出现的时间早于成熟期初级卵母细胞。组织化学研究表明，在精子发生和成熟期卵母细胞形成过程中，都存在多糖类物质积累的过程，同时卵母细胞还进行蛋白质的积累，并且蛋白质的积累早于多糖类物质的积累。     

白城地区盐碱生态环境3种植物的结构

采用光学显微镜技术对白城地区盐碱生态环境生长的豆科3种植物进行结构研究，首次在苦参叶的下表皮及叶柄的表皮上发现了盐腺。紫穗槐以聚盐和泌盐两种方式抗盐。兴安胡枝子在叶柄的皮层中以及韧皮部和木质部间以及髓细胞中都有少数含晶细胞分布。兴安胡枝子的抗盐方式属于聚盐型。

Ultrasound findings in horses with severe eyelid swelling, and recognition of acute dacryoadenitis: 10 cases (2004-2010)

Objective To report the sonographic findings, treatment, and outcome of horses with severe eyelid swelling, to describe the sonographic appearance of enlarged lacrimal glands, and to describe the clinical features of acute dacryoadenitis. Materials and methods Medical records of all horses with severe eyelid swelling that underwent an ultrasound evaluation of the globe and periorbital structures from 2004–2010 were examined. Cases were limited to those in which the eyelid swelling was so severe that the globe could not be visualized. Results Ten horses met the criteria for inclusion in the study. All cases were unilateral and acute. Marked enlargement of the lacrimal gland was found in five cases, and supported the diagnosis of acute dacryoadenitis. Eyelid abscessation was found in three horses, accompanied by mild to moderate lacrimal gland enlargement in two of the three. Enlarged lacrimal glands were slightly heterogeneous in appearance and could be differentiated from an abscess by imaging the protrusion of the gland from beneath the supraorbital rim. Only two cases of severe eyelid swelling were soley traumatic. Conclusions Severe eyelid swelling was often associated with dacryoadenitis and/or eyelid abscessation. The detection of marked lacrimal gland enlargement in horses with an acute onset of severe painful eyelid swelling is consistent with a diagnosis of acute dacryoadenitis. Ultrasonographic evaluation of eyelid swelling of any degree is warranted to determine if enlargement of the lacrimal gland, etiology notwithstanding, is an underlying or contributing cause.     

大鼠乳腺局部免疫的调节机制--泌乳期与静止期乳腺肥大细胞分布的比较

应用改良甲苯胺蓝染色法(MTB)观察了大鼠泌乳期和静止期乳腺肥大细胞的分布、形态、数量变化规律．并用阿尔新蓝一番红鉴别染色法(AB-S)进行了细胞化学分型研究。结果：AB-S染色显示，大鼠乳腺只存在黏膜型肥大细胞；无论是泌乳期还是静止期。乳腺肥大细胞大多分布于腺泡间和小叶问结缔组织中。细胞的形态各异，但细胞数量在静止期和泌乳期有显著差异。泌乳期的乳腺肥大细胞数量明显减少(P＜0．01)。乳腺肥大细胞的动态变化，可能与乳腺泌乳期腺泡上皮的生长和静止期腺泡问结缔组织细胞增生等结构变化有关。     

鸡肾上腺传出神经元的定位＊WGA－HRP法研究

将ＷＧＡ－ＨＲＰ注入７５～９０日龄鸡肾上腺内，追踪支配鸡肾上腺传出神经元的胞体。结果显示，鸡肾上腺接受交感性节前和节后神经元的支配，以节后神经元支配占主导；迷走神经的传出神经元也支配鸡肾上腺，但处于次要地位     

Development of transferred xenogeneic vole embryos in mouse uteri

An experimental model to study interspecific pregnancy using voles, Microtus arvalis, and green fluorescent protein gene‐induced transgenic mice is presented. Xenogeneic blastocysts from the vole were transferred into the uteri of pseudopregnant mice along with allogeneic blastocysts from green fluorescent protein gene‐induced transgenic mice. The uteri containing xeno‐allo combined transfers were examined from day 6 to 13 of gestation. Although the vole embryos implanted, the uteri containing vole embryos were smaller compared with those having allogeneic mouse embryos. On day 8, the uteri containing vole embryos hemorrhaged internally and no vole embryo was found in the pregnant uterus after day 11. Allogeneic mouse embryos developed normally despite the presence and abortion of the vole embryos. In uteri implanted with vole embryos, decidua were formed and numerous blood vessels were distributed around the embryo. Maternal blood cells infiltrated into the celomic cavity of the vole embryo through the discontinuous region of trophoblast. Periodic acid‐Schiff‐positive granulated metrial gland cells were remarkably increased in the decidual sites. These findings suggest that a disorder of embryo–maternal interaction might induce the appearance of numerous granulated metrial gland cells and rejection of the embryos.     

秋季中华蜜蜂（Apis cerana cerana）工蜂有分泌活性的舌腺和无分泌活性的舌腺的超微结构比较

对秋季中华蜜蜂工蜂有分泌活性舌腺（９日龄）和无分泌活性的舌腺（采集蜂）的超微结构进行了观察和比较，发现二者的舌腺细胞的超微结构存在着差异。９日龄工蜂舌腺处在分泌活性状态。细胞核发达，多突起；粗面内质网发达，成平行状排列；胞内管、胞外管中都充满电子致密度均匀的物质，即王浆物质；有大量的分泌块；线粒体内嵴排列紧密，呈板层状。而采集蜂舌腺处在无分泌活性状态。核周边异染色质增多；粗面内质网不太发达，多呈泡状；胞内管中物质为一些不均匀的电子致密度大的粗颗粒物质；胞外管中只有少量水样物质；线粒体内嵴间隙相对变大，多发现内嵴间隙呈管泡状。
