鲤属鱼类mtDNA控制区（D-环区）序列的变异性分析

采用PCR-测序技术对我国鲤属7个种、亚种和2个品种共62个个体（其中鲤的样品包括采自长江、黄河、松花江三个水系的共4个种群），进行了mtDNA控制区（D-环区）始自3^端共459bp碱基的序列测定，发现其D-环区3^端至中央保守区之间不似其他鱼类和哺乳类是一个单一的高变区，而是在其内部还插有一段长约110bp的保守区，这很可能是鲤属鱼类mtDNA D-环区自身的一个特点。

Response of fishes to the underwater D.C. field

Response to external electric field (D. C.) of three different varieties of fish namely Puntius ticto, Heteropneustis fossilis and Tilapia mossambica having different anatomical and behavioural characteristics were studied. Clearly distinguished reactions occurred one after another m all the varieties of fish with the increase in field intensity with minor specific variations. These reactions can be broadly classified into initial start (first reaction), forced swimming (galvanotaxis), slackening of body muscle (galvanonarcosis) and state of muscular rigidity (tetanus). The orientation of the organism (projection of nervous element) to the surrounding field has been found to have important bearing on the behaviour reactions. Clearly differentiated anodic taxis and true narcosis set in when fish body axis was parallel to the lines of current conduction. But with greater angle between the body axis and the current lines, fish did not show well marked reactions. Fish body, when perpendicular to current lines responded for anodic curvature and off balance swimming followed by tetanus.

猴艾滋病D型逆转录病毒筛选抗艾滋病药物实验模型的建立及应用

以药物对合胞体形成的抑制和对细胞的毒性作为检测指标，应用猴艾滋病D型逆转录病毒（SRV）／Raji细胞系统建立了体外筛选抗艾滋病药物的实验模型。AZT和天花粉蛋白可显著地抑制SRV诱导的合胞体形成，它们的选择指数（SI）分别为数13500和8812。用该模型筛选了46种来源于天然资源的化合物，结果表明有11种天然化合物有明显的抗病毒活性。

SEROLOGICAL SURVEY OF A CAPTIVE MACAQUE COLONY IN CHINA FOR ANTIBODIES TO SIMIAN TYPE-D RETROVIRUSES

Sera from 510 macaques consisting of Macaca mulatta, Macaca assamensis, Macaca fascicularis, Macaca nemestrina, and Macaca arctoides were investigated for antibodies to simian AIDS type D retrovirus (SRV) by ELISA and Western blot with viral antigens purified from supernatants of SRV-1 infected cell cultures. Of these monkeys, 104 were seropositive by ELISA; only 23 were confirmed by Western blot. The true positive reaction to SRV was found in 15 of 463 (3.2%) M. mulatta and eight of eleven (72.7%) M. assamensis.

Sphenalactones A-D, a new class of highly oxygenated trinortriterpenoids from Schisandra sphenanthera

Four novel highly oxygenated trinortriterpenoids, sphenalactones A-D (1-4), were isolated from the leaves and stems of Schisandra sphenanthera and their structures were elucidated by extensive analysis of 1D and 2D NMR data. Compounds 1-4 featured a C-27

Induced breeding of Indian carps using Des Gly^10 [D-Ala^6] LHRH ethylamide

Details are given of a study conducted in order to determine the efficacy of Des Gly^10 [D-Ala^6] LHRH ethylamide in the induction of spawning in Cirrhinus mrigala and Labeo fimbriatus . Findings shows this LHRH analogue to be a promising substitute for the pituitary gland extract which is currently used. Further studies are required to standardize the dose and method of administration in the various cultivable species in India.
