The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north

Studies of the crystal structure of endostatin have shown a compact globular fold, with one face particularly rich in arginine residues acting as a heparin - binding epitope, this site was recently shown to be involved in the inhibition of induced angiogenesis. experimental studies show that recombinant endostatin specifically inhibits the proliferation of endothelial cells in a dosedependent fashion. recombinant endostatin from bacteria is largely insoluble, but still efficient in arresting tu mor growth after injection into mice. intermittent therapy with recombinant bacterially produced endostatin reduces several experimental tumors, including lewis lung carcinoma, to a dormant state. no sign of drug induced resistance has been reported and, in the original study, the treatment dormancy appeared to persist even when therapy was discontinued. sowe regard endostatin as a promising anti - tumor drug

The characteristics of this method are : a, directly counting cell number without the influence of the metabolic state of the cells ; b, discrimination of target cells from effector cells in cell - mediated cytotoxicity assay ; c, less treatment step, and free - radioactivity ; d, high sensitivity and reliability. 2, using the above assay, immunofluorescent labeled technique, and flow cytometry, the pbmc proliferation, apoptosis, necrosis, cell cycle, activation, cytokines and membrane marker were detected. the results showed that the number of pbmc reduced, but the activity of pbmc increased dose - dependently ; the reduction of cell number resulted from necrosis and apoptosis ; the supernatant of k562 cell lines were not able to block the cell cycle, but to promote it ; the ratio of t cell subset and the expression of thl and th2 cytokines increased
