Results: It was observed that projections from IN to hypothalamus passed through the superior cerebellar peduncle, crossed in its decussation and then many of them entered posterior hypothalamic area by iontophoresis of Dextran-Texas Red to cerebellar IN. Using the methods of iontophoresis of Fluoro-Ruby and double labelling staining, it was also observed that the neurons projecting to PH in cerebellar IN were glutamatergic neurons.

结果：小脑间位核电泳Dextran-TR后示踪可见间位核神经元发出离核纤维，行走于同侧小脑上脚中，在小脑上脚交叉处交叉到对侧，然后继续走行于小脑上脚中，到下丘脑后较多纤维终止于下丘脑后区；在下丘脑后区电泳Fluoro-Ruby后可逆行追踪到小脑间位核神经元，荧光双标法显示投射到下丘脑后区的小脑间位核神经元中有谷氨酸能神经元。

On the basis of this system andpreviously morphological, physiological and biochemical studies on cucumber in vitrogynogenesis. Materials from both typical gynogenesis using M99 as induction medium andnon gynogenesis using W5 as induction medium were collected. The activities anddistribution of peroxidase and its isoenzymes, content of soluble protein and distribution of allprotein during early stage of cucumber in vitro gynogenesis and non gynogenesis wereinvestigated by biochemistry and histochemistry technology.

本试验在前期有关离体黄瓜雌核发育形态学和生理生化研究的基础上，以诱导离体雌核发育的 M99 培养基上和非雌核发育的 W5 培养基上培养的黄瓜未受精子房为试材，采用生物化学技术和组织化学技术，深入研究了离体雌核发育早期外植体内的标志酶——过氧化物酶及其同工酶的活性及分布的变化、可溶性蛋白质的含量和总蛋白质分布的变化及核酸和多糖分布的变化，为揭示离体雌核发育早期的细胞分化机制提供科学依据。

Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.

核DNA含量与进化地位的关系运用SPSS统计软件，在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示，两亚纲核DNA含量的平均值有明显差异，异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg)，该结果表明，核DNA含量在较高的分类等级，即亚纲上表现出随着进化地位的升高显著增大的趋势。

METHODS:Two hundred and seventy-one eyes of 219 patients with hard nucleus cataract, grading level IV or V, were operated with anteroposterior interceptive chop method for splitting the nucleus, and then with phacoemulsification. RESULTS:The hard nucleus of the 271 eyes were successfully routed. The average phaco time was 57.4 s.

对219例(271眼)级以上硬核白内障采取前后夹击劈核法，经充分水分离和水分层，吸除硬核前的皮质及软核后，乳化头退至前囊口上缘，劈核器轻压核下方，停止灌注让核上缘随前房变浅脱出囊袋口，乳化头顺势抵住核上缘，灌注加深前房后，乳化头滑入核后面，劈核器置核前面，前后夹击将核劈碎乳化吸出。

The cytoarchitectonic organization ofprojections to the insular cortex and the amygdala from the parvicellular ventroposterior nucleus of the thalamus andtheparabrachial nucleus in the rat was investigated by means of horseradish peroxidase -tracing technigue; The relationship of origins of afferents to the insular cortex and the amygdala from the PBN was studied by using the retrograde transport of two fluorescent tracers; Thesynaptic connections of axonal terminals with the neuronsof the PBN were observed by means of electron microscopy.

GI主要位于岛皮质的尾侧部，DI和AI主要位于首侧部；VPpc是位于丘脑腹后核和内侧丘系之间的带状区，所含细胞较小(平均14u)，其内侧部称为腹后内侧核小细胞部，其外侧部称为腹后外侧核小细胞部；PBN位于小脑上脚周围，由三部分组成：外侧亚核、内侧亚核和Kollikor-Fuse核，其中，PBl被分为7个区、PBm被分为3-4个区；杏仁核主要由三个细胞群组成：皮质内侧核群、基底外侧核群和中央核，中央核又有内侧部、外侧部和外囊部之分。

Methods The wheat germ agglutinin-horseradish peroxidase, a kind of anterograde tracer or retrograde tracer was injected unilaterally into the gigantocellular reticular nucleus. Under light microscope the fibrous connections were observed between Gi and the follow nuclei: dorsal nucleus of vagus nerve, inferior salivatory nucleus, superior salivatory nucleus, facial nucleus, ambiguous nucleus, motor trigeminal nucleus.

将顺、逆行神经示踪剂WGA-HRP注入一侧巨细胞网状核，光学显微镜下观察该核团与一般内脏运动核（迷走神经背核、上泌涎核、下泌涎核）和特殊内脏运动核（面神经核、疑核、三叉神经运动核）的纤维联系。

The present study was undertaken to explore the ultrastructural characteristics of synapses, especially the 5 HT ergic and retinal afferent synaptic connections in the hypothalamic suprachiasmatic nucleus of Tupaia belangeri chinensis, the unique native of South Chinas diurnal "primitive stock" which is more close to the Primates.
