THE COMPARISON OF BONE FORMATION, MINERALIZATION AND CRYSTAL STRUCTURE BETWEEN THE INDUCED BONE AND SELF FEMORA IN RATS / 西安交通大学学报(医学版)

By using undecalcified bone sections, accompanied by tetracycline double labeling and analysis of infrared spectrogram, the bone formation, mineralization and crystal feature of induced ectopic bone and self femora in rats were compared. The results showed that from the 21th day to the 26th day as well as from the 26th day to the 30th day of the experiment, the rate of induced bone formation, mineralization was more active than that of the self femora: on the 30th day, in the induced bone, the count of bone cell was much more, the volume of bone cell was much larger too; but the crystal structure of induced bone was indentical with that of self femora. The molecular formula was Ca_5[(OH)/(PO_4CO_3OH)_3].

HISTOCHEMICAL OBSERVATION ON THE SKELETAL MUSCLE SUCCINATE DEHYDROGENASE (SDH) ACTIVITY IN SELENIUM DEFICIENT AND VE ADEQUATE RATS / 西安交通大学学报(医学版)

Rats were fed low-Se diet (0.011ppm) or Se-supplemented diet (0.084ppm), and both groups were supplemented VE 100ppm respectively. Selenium analysis revealed that whole blood selenium concentration of rats fed low-Se diet was far lower than that of those fed Se-supplemented diet (P
