Mast Cells in Renal Cancer: Clinical Morphological Correlations and Prognosis.

Morphofunctional activity of mast cells in renal cancer is studied on specimens from the center of the tumor, peritumorous zone (with an obligatory fragment of the pseudocapsule), and from renal tissues maximally distant from the tumor. The counts and areas of tumor cells were maximum in the peritumorous zone in comparison with intact kidney tissue and central zone of the tumor. Analysis of correlations revealed a direct correlation between the tumor cell count in the peritumorous zone and some clinical morphological parameters of the tumor (anaplasia degree, size, presence of invasion and metastases, and angiogenesis).

A preclinical study of the immunocorrection action of the sum of active substances isolated from ethereal-oil plants Coluria geoides (Pall.) Ledeb. (Rosaceae family) with respect to experimental immunodeficiency showed that preparations relieve symptoms of immunodeficiency caused by the administration of cyclophosphan: suppressed synthesis of anti-erythrocyte antibodies (agglutinine) and proliferative processes in the spleen.
