[Isolation of canine rotavirus and study of its immunobiological properties].

Canine rotavirus was isolated in MA104 roller culture of rhesus macaque cells. Two passages in gnotobiotic puppies and two in colostrum-free puppies resulted in isolation of strain P of canine rotavirus. After 20 passages in MA104 culture the virus was adapted to MDCK culture.

[Treatment of heart failure by draining blood from the coronary sinus].

A method of coronary sinus drainage is suggested for the treatment of acute heart failure. This ensures an increase in the arteriovenous gradient of pressure in the coronary system by decreasing the pressure in the coronary sinus which leads to an increase in the orthograde myocardial circulation and systemic pressure as well as to improved cardio-mechanics.
