nzyme cytochemical method and real time image processor-analyzer were utilized to investigate the alternations of SDH and ACPase in hipocampal CA3 neurons of aged Wistar ratsand at the same time the anti-aging effects of Ginsenoside on the neurons were observed.27femal Wistar rats were divided into three groups at random, group 1(young,3 months),group 2(27 months) and group 3(21 months).All of the group 3 were administrated withGinsenoside from 21st to 27th month.The results showed that the activity of SDH was...

nzyme cytochemical method and real time image processor-analyzer were utilized to investigate the alternations of SDH and ACPase in hipocampal CA3 neurons of aged Wistar ratsand at the same time the anti-aging effects of Ginsenoside on the neurons were observed.27femal Wistar rats were divided into three groups at random, group 1(young,3 months),group 2(27 months) and group 3(21 months).All of the group 3 were administrated withGinsenoside from 21st to 27th month.The results showed that the activity of SDH was decreased,while that of ACPase increased in CA3 neurons of aged rats.This experiment indicated that Ginsenoside could increase the activity of SDH and decrease the activity of ACPase,which provided certain evidence of cytochemical changes of the enzyme caused by theanti-aging effects of Ginsenoside.

本实验应用酶细胞化学方法观察了老龄大鼠海马CA3区神经元的琥珀酸脱氢酶(SDH),酸性磷酸酶(ACPase)的衰老变化,同时对比观察了人参茎叶皂甙的抗衰老作用。实验数据由彩色显微图像分析系统进行定量分析。实验结果提示老龄时海马CA3区神经元SDH酶活性减弱,ACPase活性增强。而人参茎叶皂甙具有促进神经元SDH酶活性,降低ACPase活性的作用。本结果为老龄时学习记忆能力下降及人参茎叶皂甙延缓衰老提供了一定的酶细胞化学变化的依据。

Using in vitro flower experimental system of Taihangia rupestris Yü et Li in which development or abortion of stamens could be controlled by temperature, the cytological and cytochemical changes in both development and abortion processes of the stamens were comparatively studied.Cytological changes of the stamen abortion initiated at the microsporocyte stage before which normal cytological process were seen from stamen primordium to primary microsporocyte stage. However, despite of the normal cytological...

Using in vitro flower experimental system of Taihangia rupestris Yü et Li in which development or abortion of stamens could be controlled by temperature, the cytological and cytochemical changes in both development and abortion processes of the stamens were comparatively studied.Cytological changes of the stamen abortion initiated at the microsporocyte stage before which normal cytological process were seen from stamen primordium to primary microsporocyte stage. However, despite of the normal cytological process, polysaccharide accumulation was never observed in the cells of anther and filament where as in the normally developing stamens polysaccharide accumulation must largely occurred in those cells mentioned above.The author considered that such cytochemical changes prior to the morphological deviances might be of great significance to approach the cause of temperature induced male sterility.

应用受温度控制的太行花 ( Taihangia rupestris Yü et Li)雄蕊发育或败育的试管花实验系统 ,比较研究了雄蕊发育和败育过程的细胞学和细胞化学变化。结果表明 ,雄性败育过程具有以下的细胞学和细胞化学特点 :雄蕊败育的细胞学变化发生在小孢子母细胞时期。在此时期以前从雄蕊原基到初生小孢子母细胞时期 ,其细胞学过程是正常的 ;在这正常的细胞学过程时期 ,细胞中没有任何多糖的累积 ,而在正常发育的雄蕊中这种累积本应在花丝和花药中大量发生。作者认为 ,这种先于形态学变化的细胞化学变化对于寻找由温度引起的雄性不育的原因可能是十分重要的

The VE, FE and plasme mebrane of Clupea pallasi eggs was examined with electron microscope and cytochemical techniques. The cortical alveolar exudate is involved in the transformation of the VE into the FE during the process of fertilization. The VE is composed of five layers. The outmost (first) layer of the VE is less dense and homogeneous in general, but there is a dense substance on the outside of the surface of the VE, which is called the border in this paper. The border is more glycoploternrich and some...

The VE, FE and plasme mebrane of Clupea pallasi eggs was examined with electron microscope and cytochemical techniques. The cortical alveolar exudate is involved in the transformation of the VE into the FE during the process of fertilization. The VE is composed of five layers. The outmost (first) layer of the VE is less dense and homogeneous in general, but there is a dense substance on the outside of the surface of the VE, which is called the border in this paper. The border is more glycoploternrich and some small radial canals with opening proes (average diameter 0.8 ̄1.6μ) cross through this layer. It is thicker (average 17μ) than the other layers (layers Ⅱ-Ⅴ: 0.48μ、11.3μ、0.23 ̄0.3μ、6.6μ). The second and fourth layers of the VE are thin layers composed of granule with mark by RR. The third and fifth layers composed of thin lamella with mark by RR also. There are differences between the VE and FE in the thickness and ultracytochemical. The border on the surface of the outmost layer of the FE is not stained by RR and PTA by 40min after fertilization. There are three types of cortical alveolar in the egg cortex, and some small alveolars contain granules stain with PTA between them. The granules secreate on the surface of the egg plasm membrane before fertilization. Cortical alveolar exudate forms a new layer on the outside of the surface of the FE. The surface substances of the plasma membrane of unfertilized and fertilized Clupea Pallasi eggs always change. There is membrane like structure stain with Rich RR on the outside of the surface of the plasma membrane which is touched by cortical alveolar. VE: Vitelline envelope FE: Fertilization envelope. PTA: Phosphotungstic acid. RR: Ruthenium red.

本文使用透射电镜,细胞化学和扫描电镜等方法,在亚微水平上对黄海太平洋鲱鱼(ClupeapalasiCvv,&Vol.)卵黄膜和受精膜的结构以及皮层小泡在卵黄膜转化为受精膜过程中的作用,受精卵新质膜的形成及其细胞化学变化等进行了研究。观察到,太平洋鲱鱼卵黄膜由5层组成,皮层小泡参与了受精膜的形成,在卵黄膜转化为受精膜的过程中,5层都发生不同程度的形态和糖蛋白及PAS阳性物质的变化。另外发现太平洋鲱有3种皮层小泡存在。在皮层反应中,第一种皮层小泡在受精后3min内迅速破裂,未受精卵尚含有PTA染色的小颗粒从小泡中泌出,其界膜形成了质膜的一部份。受精后,此质膜与皮层小泡形成的质膜相同排列构成卵子新的质膜。另外,还发现第一小泡顶部,与卵子质膜相接触的卵子表面有富含糖蛋白的泡状结构。卵子质膜表面糖蛋白及PAS阳性物质,随时间推延而不断发生变化
