[Autoradiographic study of liver regeneration after treatment with carbon tetrachloride and heterologous antihepatic serum].

The authors carried out an autoradiographic study on the regeneratory processes in liver of 130 rats, which were treated with carbon tetrachloride and heterologous antiliver serum at various dilutions. The obtained results showed that this serum stimulated the synthesis of DNA in the parenchymal mesenchymal cells of liver, damaged diffusely. The effect of stimulation on DNA-synthesis in the animals of the experimental group, treated with 0,5 ml of heterolougous antiliver serum in dilution of 1:10 with saline, was mostly manifested. According to the authors the stimulation of DNA-synthesis was accomplished most probably by means of the mechanisms of the so called "immune enhancement".

[Origin of rectosigmoid cancer from precancerous processes].

Three hundred sixty two patients with rectosigmoid cancer are examined by rectoromanoscopy and biopsy in order to establish those of them with manifestations of a proceeding precancer process. Cancer, originated on the base of single polypus was established in 50,94 per cent and 7,54 per cent in relation with preceeding generalized polyposis, in 30,19 per cent malignant villose tumor is concerned, in 4,71 per cent -- cancer, originated on the base of preceeding ulcerohemorrhagic proctocolitis and in only 1,91 per cent -- malignant chronic fibrosclerosed hemorrohoids. Precancer process is established in 29,29 per cent in all of the examined 362 patients with rectosigmoid cancer and in 70,71 per cent of the cases no manifestations of preceeding precancer disease was established, i.e. the malignancy ratio with established precancerosis towards malignancy without established precancerosis is approximately 1 : 2,5. That fact requires acute attention in all cases with established precancerosis of the terminal segment of large intestine, treatment without delay and dispensary control.
