Effects of hydroxy safflower yellow-A on tumor capillary angiogenesis in transplanted human gastric adenocarcinoma BGC-823 tumors in nude mice.

Objective: To study the effects of hydroxy safflower yellow A (HSYA) on tumor capillary angiogenesis in transplanted human gastric adenocarcinoma BGC-823 tumors in nude mice.

Methods: BGC-823 cells were injected subcutaneously into the right anterior armpit of nude mice to establish an animal model of transplanted tumors. After 24 h, 18 nude mice injected with tumor cells were randomized into model, control, and HSYA 0.

[Theoretical study on thirteen or fourteen incompatible medicaments and opposite drug properties of Tujia ethnic medical science].

[Effects of HSYA on expression of bFGF protein and MMP-9 in BGC-823 transplantation tumor of nude mice].

Objective: To investigate the effects of hydroxy safflor yellow A (HSYA) on the expression of bFGF protein and MMP-9 mRNA or protein of transplantation tumor of gastric adenocarcinoma cell line BGC-823 in nude mice.

Method: The BGC-823 cells were subcutaneously injected into the right anterior armpit of BALB/C nu/nu nude mice, and the animal model of transplantation tumor was established. The experimental groups were treated with HSYA at concentration of 0.
