This study was aimed to investigate the inhibitory effect of combined transfection of p53 and angiostatin (AS) genes on K562 cells and to explore its mechanism.

Objective To investigate the interference and the mechanisms of Bcl-2 and HER-2 genes antisense oligodeoxynucleotides combined transfection in the human tongue carcinoma Tca8113 cell lines.

PART ONEOBJECTIVE: To investigate the proliferating inhibition and the mechanisms of c-erbB-2 and c-raf-1 genes antisense oligodeoxynucleotides combined transfection in the human ovarian carcinoma SKOV3 cell lines.

Objective:To investigate the influences of the sperm of male rats impact,when octyl phenol,nonylphenol joint exposured.

Now there are lots of reports about reproduction system function damage induced by formaldehyde or benzene, but few about reproduction toxicity of joint exposure to the two substances.

A contrast test on sizing-dyeing machine shows that a better effect is acquired,and the influence of "wet inside and dry outside" on warp sizing is analyzed.

This paper narrate briefly the present situation of the joint machine of printing and dyeing and the faults of YCT series electrical machinery in synchro-drag.

Compared with YCT series electrical machinery, it illustrates the feasibility of using YYTRW series electrical machinery in the joint machine of printing and dyeing instead of YCT series electrical machinery.
