Correlation between VEGF expression and angiogenesis in breast carcinoma.

Objective: To analyze the role of vascular endothelial growth factor (VEGF) secreted by tumor cells in angiogenesis of breast carcinoma using image morphometry.

Study Design: Thirty-four cases of node-negative breast carcinoma were used in the study. There were 6 grade 1, 20 grade 2 and 8 grade 3 tumors.

Effective human defense against E. histolytica: high amoebicidal activity of lymphocytes and monocytes in amoebic liver abscess patients until 3 months follow-up.

Adherence of pathogenic Entamoeba histolytica trophozoites mediated by Gal/GalNAc lectin is a prerequisite for killing naïve T cells and monocytes but the activated T cells and monocyte derived macrophages (MDMs) not only resist the attack but can kill the parasite. In the present study, we have analysed the adherence and cytotoxicity of the immunecompetent cells from patients of amoebic liver abscess at the time of their diagnosis and after 3 months to elucidate the development of cell mediated cytotoxicity, a major mechanism of resistance to amoebic infection. The results show that CD3+ cells from amoebic liver abscess cases, when stimulated, in vitro, bound E.
