Abstract
Objective:
To locate nitric oxide synthase (NOS) in the chicken vestibular system.
Method:
The frozen section were processed for NADPH-d histochemistry in a solution containing NADPH and nitroblue tetnazolium (NBT) to demonstrate NOS positive reactivity.
Result:
NOS positive staining, black-blue in color, was seen at the nerve ending, nerve fibers of the utricul and saculla and ampiculium. Ganglion cells had different activity. The shape of the cells seems to be round or oral.
Conclusion:
Collectively, data indicate the presence of active NOS in these tissue and suggest modulation of vestibular neurotransmission by nitric oxide.
