Description:

Experiments were carried out on four species of rodents: Wistar rats, bank voles, European pine voles and field voles. Oxytetracycline (OTC) was injected at different times of the night and a day in doses from 10-20 mg/kg of body weight and the animals killed 6 to 12 hours later. Intensity of yellow fluorescence was estimated in ultraviolet light in the following bones: skull, fore and hind leg and spine, as a measure of the rate of incorporation into the growing bone. It was found that intensity of incorporation in the bones is not uniform throughout the course of 24 hours, but is higher during the active period of the animal's diurnal rhythm. This provides grounds for assuming that the diurnal rhythm of sceleton growth is divided into periods of varying rate of growth. Doświadczenia przeprowadzone były na 4 gatunkach gryzoni - szczurach laboratoryjnych rasy Wistar, nornicy rudej, darniówce i norniku burym. Zwierzętom wstrzykiwano chlorowodorek oksytetracykliny (OTC) w róznych porach doby i zabijano je po 6 lub 12 godzinach. Następnie obserwowano w świetle ultrafioletowym intensywność żółtej fluoroscencji w kościach: czaszki, kończyny przedniej i tylnej oraz kręgosłupa, co stanowi miarę tempa wbudowywania się podawanej substancji w rosnącą kość (Ryc. 1).
