heat-labile

AIM: To explore the immunoregulatory functions of Escherichia coli heat labile enterotoxin B subunit ( LTB) and its possible mechanism.

目的：探讨大肠杆菌热不稳定肠毒素B亚单位（LTB）的免疫调节功能及其可能的机制。

Of the 31 serotypes ( Var.) and a strain of Salmonella(ⅲ) b ( 48: a: Z55) with heat-labile K antigen were discovered in China for the first time.

有6个型（变种）为国内首次检出，并发现一株带有不耐热表面K抗原的沙门氏菌Ⅲ~b（48∶a∶Z~（55））。

A heat labile, dialysable unknown factor in plasma was found to be capable of catalyzing the oxidation of DMAP to a red quinoid product. The oxidized DMAP may interfere with the determination of MetHb, when the DMAP concentration is high.

实验发现，血浆中有一热不稳定，可经透析除掉的小分子物质能催化DMAP氧化成红色的醌，干扰MetHb测定。

Coli heat-labile enterotoxin B subunit ( LTB), and analyse the biologic and immunologic characteristics of the fusion protein.

coli不耐热肠毒素B亚单位（LTB）的重组融合蛋白，并对其基本的生物学及免疫学特性进行研究。
