[Use of a biological model of isolated overload of the skeletal muscle for determination of the effect of anabolic steroids].

The authors tested a new biological model for the quantitative determination of the anabolic effect of steranobols of prolonged action. The principle of the method consists in creation of an isolated overload of the skeletal muscles of the shin (m. soleus and. m. plantaris) following section of the tendons of their synergist--m. gastrocnemius in rats, with the subsequent recording their weight gain caused by the administration of anabolic steroid. The method is simple, sensitive and permits to use the animals of different weight and sex without subjecting them to castration.
