猴艾滋病D���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���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.

Phomoeuphorbins A-D, azaphilones from the fungus Phomopsis euphorbiae

Four azaphilones, named phomoeuphorbins A-D (1-4) were isolated from cultures of Phomopsis euphorbiae, an endophytic fungus isolated from Trewia nudiflora. Structures of 1-4 were established on the basis of spectroscopic analyses, including application of

Periglaucines A-D, anti-HBV and -HIV-1 alkaloids from Pericampylus glaucus

Four new hasubanane-type alkaloids, periglaucines A-D (1-4), and three known alkaloids, norruffscine (5), (-)-8-oxotetrahydropalmatine (6), and (-)-8-oxocanadine (7), were isolated from the aerial parts of Pericampylus glaucus. Their structures were eluci

Bell-shaped D-serine actions on hippocampal long-term depression and spatial memory retrieval

D-Serine, the endogenous coagonist of N-methyl-D-aspartate receptors (NMDARs), is considered to be an important gliotransmitter, and is essential for the induction of long-term potentiation. However, less is known about the role of D-serine in another for

三黄果蝇(Drosophila trilutea)近黄果蝇(D. paralutea)的有丝分裂中期染色体

用产于日本的D. paralutea和产于昆明的D. trilutea三龄幼虫的脑神经节作染色体制片,进行C-带染色观察。其正常染色体与亚组种D. takahashil的染色体十分相似,染色体数均为2n=8。发现在所有的分裂细胞中几乎都包含1对微小染色体。图4参1
