Abstract/OtherAbstract:
Separate groups of male rats were tested in the forced swim test on the third Tuesday of each mo for 14 mo. A distinct pattern was observable in their immobility response such that animals were most immobile during the winter months (Dec-Mar) and least immobile during the summer months (June-Sept). Bicarbonate-carbon dioxide levels were significantly correlated with immobility times (r = 0.48), as were glucose (r = 0.34) and phosphorus (r = -0.33) levels, whereas corticosterone and testosterone levels were not significantly correlated with immobility. These results indicate that there is a circannual rhythm in the floating behavior of rats in the forced swim test.
