Miscellaneous fish from the catches of shrimp trawlers constitute a major portion of the marine fish catch in India, its quantity in annual landing being of the order of 50,000 tons. At present it is often not brought to the shore since it fetches only very low price. It consists of several species and is a cheap source of animal protein. Attempts are made in India in various centres (Anon. 1972-73) to utilise them effectively by formulating various speciality products acceptable to consumers.

以化合物对HIV1诱导C8166细胞形成合胞体的抑制实验和化合物对HIV1感染细胞的保护实验作为初筛方法,筛选了来源于7科17种植物的47个样品,其中8个样品经测定是核糖体失活蛋白(RIPs),其余为粗提蛋白。进而测定了初筛有抗HIV活性的化合物对共培养、急性和慢性感染的HIV1p24抗原表达水平的影响,用间接荧光染色检测这些化合物对HIV抗原阳性细胞率的影响,以确证其抗HIV活性。天花粉蛋白(TCS)、南方栝楼蛋白峰Ⅴ、南方栝楼蛋白峰Ⅵ均显著地抑制合胞体的形成;巴Ⅱ、丝瓜子蛋白、油瓜根蛋白、木盍藤子蛋白有一定的抑制作用。老鼠拖瓜蛋白、大叶木鳖子根蛋白、西双版纳根Ⅱ等粗提蛋白有显著的抑制作用。RIPs不能保护HIV1感染细胞的死亡。TCS显著地抑制了HIV1急性感染中p24抗原的表达,减少了HIV抗原阳性细胞数,但它们均不影响共培养细胞融合、HIV1慢性感染中p24抗原表达水平。结果表明,除TCS等已知RIPs外,还有一些新的RIPs具有不同程度的抗HIV活性。

The prototype combination wire rope (Cift-CWR 1) developed for deep sea trawling was further studied for improvement, optimisation of efficiency and standardization. A series of improved prototype combination wire ropes (Cift-CWR 2 to 6) were twisted and evaluated their mechanical properties and reported in this paper with recommendations for a standard 17mm dia combination wire rope of 6S (7C+8+1 Scr) + 6 Crs(6+1+1 Crc) construction.

This workshop followed on from two previous workshops held in Colombo, Sri Lanka, 2012 and Kochi, India in 2013. The 14 microsattellite markers had previously been developed for Indian Mackerel (Rastrelliger kanagurta) were used on 31 tissue collections from all eight countries were genotyped in India.

放射免疫和生物测定法表明3只大熊猫在发情高峰期均出现雌二醇和促黄体素高峰; LH峰值出现在E_(2)峰值以后。根据雌兽在发情期血清和尿液中这二种激素的变化可为选择人工授精最佳时间提供可靠的理论依据。图2表2参15

以Sumner法和界面铺张-硝酸银技术观察, 表明尼罗罗非鱼的2n=44, 核型可分为3组,各具4对亚中着丝粒染色体、17对亚端着丝粒染色体和1对端着丝粒的特大染色体。结构异染色质主要分布于着丝粒附近, 其中Nos.6、8、15亚中着丝粒染色体短臂全部深染。带有银染核仁组织者(Ag-NORs)染色体的数目为2—6条, NORs均位于6、8、15亚中着丝粒染色体短臂。银染色可清楚显示联会复合体(SC)结构和减数分裂行为。SC组型与有丝分裂染色体的组型有较好的一致性 。图版2图2表2参13

小麦SC以多点式起始方式于偶线期开始形成; 随SC的发育, 新的SC形成和巳 有SC片断的延伸并存; 在同一核内不同二价体之间, 染色体配对和SC形成并不 同步; SC成熟于粗线期, 而以破碎方式解体, 消失于双线期。在偶线期近观察 到由同祖配对形成的多价体, 但在随后阶段中这些多价体消失。对Ph基因的可能 作用机制作了分析和讨论。图版2参18
