[Steroid hormone receptors in malignant mammary gland tumors in dogs].

The content of estrogen (ER) and progesteron receptors (PR) were studied as related to histological type, the degree of malignancy and growth rate of spontaneous canine mammary carcinomas. No correlation was found between the ER and PR amount, histological type and degree of malignancy. Inverse correlation was detected between ER and PR and the growth rate.

[Antineoplastic and toxic effects of blastolysin in the treatment of spontaneous mammary cancer in dogs].

The anticancer activity and toxicity of blastolysin were studied in 13 dogs with mammary cancer using two different schedules. The agent was given 5 times in a dose of 2.5-10 mg/kg with a 72 h interval (the first schedule) and 10 times in a dose of 0.
