The cytosol TP activity, PD-ECGF/TP – protein expression and microvessel density in tumor (T) and normal endometrium (E). Results are expressed as mean ± SD (standard deviation), p < 0.001. A.) TP activity – The cytosol TP activity measured in micromoles of T × mg protein-1 × h-1 as described in Materials and Methods. Tumor samples were from 43 endometrial cancer patients and normal endometrium from 16 women treated surgically due to nononcological reasons. B.) TP/PDECGF – PD-ECGF/TP – protein expression; The extent of immunohistochemical expressions was classified into 0, 1, 2, 3 grades as described in Materials and Methods. C.) MD – Microvessel density. Microvessel counting, performed according to the Weidner's method  measured as described in Materials and Methods.
