24-hr variations in the content of neurosecretory material “Gomori-positive”; in the cells of nucleus preopticus were studied in rainbow trout maintained in natural light, complete darkness and continuous artificial light. 24-hr variations in the content of neurosecretory material “Gomori-positive”; in the cells of nucleus preopticus were studied in rainbow trout maintained in natural light, complete darkness and continuous artificial light. Brains were taken from trout every six hours during a 24-hr period and fixed in the Bouin's liquid. Slices were stained with aldehyde fuchsin and the content of the neurosecretory material was determined with a cytophotometer. Statistical significance was calculated with the Student's t-test. On basis of the obtained results the following was stated: 1. Circadian rhythm in the content of neurosecretory material “Gomori-positive”; in the cells of nucleus preopticus of rainbow trout. 2. Variations in the circadian rhythm in trout kept in continuous light or complete darkness compared with trout kept in natural lighting conditions. 3. No effect of various light conditions on the total of the neurosecretory material content “Gomori-positive”; in the cells of nucleus preopticus in the trout under investigation. |
