Notes:
The present investigation was undertaken to examine possible noise-induced alterations in adrenal fasciculata cell (AFC) metabolism, and also to determine if the magnitude of these changes differs in male versus female rats. Wistar rats approximately 3 months old were exposed to intense noise for 60 min (100 dB, re 2 × 10-5 N(m2)-1, 350-20 000 Hz); control rats were house under identical conditions, at an ambient noise level of 40-60 dB. Adrenal fasciculata cells (AFC) from each animal were examined for noise-induced alterations in Feulgen-DNA reactivity (as an indicator of chromatin template activity) and Coomassie-total cell protein levels using scanning-integrating cytophotometry. The results provide evidence that intense noise elicited a marked AFC metabolic enhancement in both male and female rats; the degree of this enhancement was more pronounced in males. This disparity may be due to pre-existing differences in male versus female AFC enzymatic capability and subsequent responsiveness to noise-induced activation.
