The effect of trasylol (Trascolan "Polfa") and p-aminomethylbenzoic acid (Pamba "Germed") on the experimental metastases of transplantable melanotic melanoma in golden hamster (Mesocricetus auratus, Waterhouse).

The influence of two proteinase inhibitors -- Trasylol (Trascolan "Polfa") and PAMBA ("Germed") -- on experimental metastases of melanotic melanoma has been studied in golden hamsters. Animals were injected intravenously with tumour cells (5x10(5) or 10(6) in 0.2 ml of saline). They obtained protease inhibitor intraperitoneally one hour prior, or one hour after melanoma cells injection. One group of hamsters were also inoculated with tumour cells preincubated 10 min. in saline containing Trasylol or PAMBA. A diminished number of experimental metastases to the lungs in each group has been observed.
