1. The results of histochemical investigation of the action of some anti- 

 tumour drugs on transplanted rat and mouse tumours will be reported. 



2. The changes of the tumour cells and connective tissue stroma found 

 by means of more than 10 various histochemical methods will be demon- 

 strated. 



3. The application of the histochemical methods, e.g. démonstration 

 of nucleic acids, neutral fat, glykogene, metachromasia, some enzymes 

 (phosphatase, esterase, oxydative enzymes etc.) showed their great value 

 for expérimental studies in the new branch of oncology-cancer chemo- 



therapy.
