First, we made a model of exhaustive exercise in rats, and used sucessfully the model in this study. We studied the effects of exhaustive exercise on adhesive behaviour of leukocytes in mesenteric venules by using an intravital microscope video system Its results indicated that the adhesiveness of circulating leukocytes to mesenteric venules enhanced after exhaustive exercise in rats.

首先，本文以游泳方法建立了大鼠模拟运动力竭模型，并成功地将此模型运用到本研究中；设计制作了肠系膜固定有机玻璃板，组成了一套活体显微观察实验系统；研究了大鼠运动力竭前后肠系膜微循环中白细胞粘附行为，结果表明：大鼠运动力竭后肠系膜微循环血流流态发生了明显的改变，大鼠运动力竭后肠系膜微循环中白细胞粘附性增强、白细胞滚动速率降低、在体白细胞变形性减小，将影响微循环正常的灌注，是导致微循环障碍发生发展的一个重要原因，进而最终表现为机体运动能力和运动质量下降。

Megaspore development and abortion of"Pingyi Tiancha"Compar-ing with regular developing megaspore of normal M.baccata,the megasporemother cellof"Pingyi Tiancha"could form mono-nucleus embryo sacby perhaps irregular meiosis,then most of sexual MES depauperatedand degenerated,finally aborted,or only a few further developed.Of asexualembryo sac,one or more large cells at the chalazal end of nucellus developed in-to one to more asexual embryo sac initials.After the competition between sexu-al embryo sacand asexual embryosac,most ovules only had one asexual embryo sac matured.

平邑甜茶大孢子的发育和败育与正常发育的山定子大孢子对比，平邑甜茶大孢子母细胞经减数分裂能形成单核胚囊，之后多数有性胚囊萎缩、退化而败育，只有极少数进一步发育；而无性胚囊则从胚珠合点端1个或多个较大的珠心细脆形成并首先发育为一个或多个无性胚囊原始体；经过有性胚囊和无性胚囊以及无性胚囊和无性胚囊之间的竞争，多数胚珠只有一个无性胚囊成熟。

Other three alien translocation lines referring to chromosome Lr.14 of L.racemosus were also induced via irradiated pollens.After irradiated by gamma raysof 1KR does,the pollens of T.aestivum-L.racemosus Lr.14 disomic addition lineswere used to pollinate wheat varieties"Yangmai No.5"and"Mianyang No.11".M1plants have pairing between wheat chromosomes and Lr.14 ofL.racemosus at PMCMI stage were self-pollinated,and the M2 seeds used to be Giemsa C-banded andfluorescence in situ hybridized.As the result,three alien translocation lines wereobtained and T12 was observed to have distal translocation chromosomes betweenLr.14S and a wheat chromosome segment(TW-Lr.14S·Lr.14L).T13 wasidentified to contain mostly-alien-translocation chromosome(TLr.14L·Lr.14S-W).T14 was proved to contain a translocation between Lr.14L and 6BS,with approximatebreakpoint at 6BS2.2 region, FL0.22 in the short arm of chromosome T6BL.6BS-Lr.14L.

Methods: Fifty-four female SD rats (8-month-old) were randomly divided into three groups, 18 rats in each group, They included a sham-operated group, an ovariectomized group and a tonifying kidney recipes therapy group, After 3 months, the animal models of osteoporosis were established, pour titanium smooth columnar implants were placed in the proximal metaphyses of left tibiae of the rats.

选用纯种8月龄雌性SD大鼠54只，随机分为3组：假手术组，卵巢切除组，卵巢切除加中药治疗组，每组18只。切除卵巢切除组及中药组大鼠双侧卵巢，假手术组大鼠仅切除双侧卵巢附近的脂肪组织。术后3个月，在三组大鼠胫骨近中干骺端分别植入纯钛光滑柱状种植体。

Intra-portal alopecia was observed in all rats which received 30 Gy and some rats which received 20 Gy. The abnormal neurological signs were not found in all the rats, but the tend of body weight increase was less pronounced in 1-3 months in the irradiated rats than those unirradiated.

所有存活大鼠无异常神经系统体征，30Gy剂量组全部和20Gy部分大鼠照射后射野内有脱毛，而且照射组大鼠在受照后1至3个月期间，体重的上升趋势低于未照射组大鼠，但无统计学差别。

ResultsThere was no expression of Caspase-3 in group A. The expression of Caspase-3 in group C was decreased compared with that in group B（P＜0.01. In groups B and C, expansion and vacuolization of mitochondria, swollen neurons and apoptotic bodies appeared, which suggested that WBH could induce neuron injury, and the neuron injury in group C was more severe than that in group B.

结果A组大鼠海马区神经元无Caspase-3表达，B、C两组大鼠海马区神经元有Caspase-3表达，B组较C组Caspase-3表达平均灰度值减小。B、C两组大鼠海马神经元超微结构发生改变、细胞器水肿，部分线粒体空化，内质网稀疏，突触前膜、后膜结构不完整，可见自噬体结构；B组大鼠的神经元超微结构损害较C组轻。

In order to assess the size selectivity for fishes of beam trawl fishing in offshore of the East China Sea,experiments of codends with different mesh configuration,including diamond mesh, square mesh and turned through 90° diamond mesh(T90) in 4 sea trials have been carried out and catch data were collected by comparative fishing method.

选择性分析结果显示，对于短吻舌鳎，横向使用的菱形网目网囊L50(50%选择体长)最大，而SR最小，菱形网目网囊L50最小，而SR最大；对于棘头梅童鱼和小黄鱼，菱形网目网囊的L50最小，SR最大，横向使用的菱形网目网囊L50最大，而方形网目网囊SR最小；除不同结构的网目扩张程度不同以外，鱼体体型结构的特殊性以及网囊结构也可能是导致选择性差异的主要原因。
