摘要: Stereoscopic observation via an implanted sight glass in mice bearing transplanted methylcholanthrene-induced A-cells showed tumorivascular hemorrhage at 1–2 h after tumor necrosis factor (TNF) administration, congestion 4–6 h, and hemorrhage, congestion, blood circulation blockage 24 h. Histological examination TNF administration to similar methylcholanethrene-induced A-cell transplants thrombus formation the vasculature 4 thereafter. Suppression of this with heparin had no apparent influence on necrotic response, growth inhibition or complete cure rate following tumors. The results suggest that direct toxicity is a overall antitumor mechanism TNF.
