Abstract:
Objective:To quantitatively measure the blood flow of bone and muscle tissue by the radioactive microsphere techniques.Methods:The erythrocytes of hoptoad labelled with the 99m Tc were used as the radioactive microsperes.Each injection consisted of 10 6 microspheres.The blood flow of bone and muscle tissue of 10 rabbits were examined via injection of hoptoad erythrocytes labelled with the isotope; the blood flow of tissues were calculated according to the artery withdraw rate and radioactive counting of samples and reference blood.Results:The blood flow of femurs [(8.94?0.45) ml/(min?100 g)] was the highest among all the long bones,the blood flow of humeral metaphysis [(7.73?0.68) ml/(min?100 g)] was significantly higher than that of diaphysis and epiphysis ( P
