The effects of plasma low high-density lipoprotein cholesterol on platelet cytosolic free calcium and release reaction / 中国实用内科杂志

ABSTRACT

Objective To discuss pathogenic effects of low high-density lipoprotein cholesterol(HDL-C)on atherosclerosis and thromboembolism,the influences of HDL-C on platelet cytosolic free calcium concentration([Ca2+]i),platelet release reaction products beta-thromboglobulin(?-TG)and platelet factor 4(PF4)were observed in dyslipoproteinemia patients with low HDL-C.Methods i,?-TG and PF4 were measured by fluorescent probe Fura 2-AM and ELISA skills respectively,in 42 patients with low HDLC(LHDL-C)and 25 healthy controls(CONT).Results Compared with those in CONT group,the platelet[Ca2+]i,?-TG and PF4 were all higher in LHDL-C group(all P
