In 1970′s a prevailing hypothesis postulated herpes simplex virus in cervical cancer aetiology,but Hausen has made seminal observations that identify novel human papilloma viruses as key contributors to cervical cancer and hybridization technique of nucleic acid has proven it.After the discovery of human immunodeficiency virus(HIV) by Sinossi and Montagnier,they held the evolutional history of HIV.The article objectively evaluates the role in the discovery of HIV,played by Gallo.

Objective To investigate the influence of glycine supplement on partial biochemical indicator in exhaustive exer‐cise mice .Methods Divided Kunming′s male‐mice into 3 group(10/group):exhaustive swimming group(E) ,exhaustive swimming group with glycine supplement(G) and silent control group (S) .Mice in the G group was treated with 4‐weeked intragastric admin‐istration of glycine ,while mice in other 2 groups received physiological saline .After 4 weeks ,mice in E and G group did the exhaus‐tive swimming exercise .After sampling ,the activity of complement hemolytic activity was measured ,and the serum levels of some biochemical indexes were determined .Results Time of exhaustive swimming in G group was significantly longer than E group(P<0 .01) .After exhaustive swimming ,the ALT ,AST ,ALP ,LDH ,CK ,N ,Fe3+ and CHA in E group were significantly changed com‐pared with S group(P<0 .01);while those indicators in G group were significantly improved than E group (P<0 .01) ,the ALP and LDH level can regain to the level of S group (P>0 .05) .Conclusion Exhaustive swimming mice can have part indicator abnormali‐ty ,but Glycine supplement can effectively improve that condition and enhance the exercise ability to some extent .
