[Characteristics of the growth rate of the transplantable sarcoma 45].

The growth dynamics of the experimental tumour was analyzed in 180 mongrel rats with sarcoma-45 inoculated intramuscularly and subcutaneously. One of the approaches to the calculation of doubling time is estimated. It is suggested that the changes of the C-45 tumour size may be described according to the function V = A exp(T/B)--C.
