Thromboplastic and fibrinolytic activities in various organs of congenitally athymic nude mice

Thromboplastic and fibrinolytic activities in various organs of congenitally athymic nude mice were estimated. These activities varied from one organ to another and the organs were divided into six groups of possible combinations of these activities. The lung revealed high thromboplastic and high fibrinolytic activities, while the liver showed low thromboplastic and low fibrinolytic activities. The pattern of distribution of these activities in various organs of nude mice was almost similar to that of rats and mice with normal thymus. No plasmin activity was found in all organs.
