Summary
Nicotinamide adenine dinucleotide hydrogen phosphate-diaphorase (NADPH-d) histochemistry was used as a marker for nitric oxide synthase (NOS).
In the rabbit thymus, NADPH-d staining was observed between the capsule and corticomedullary junction in radially oriented blood vessels in the cortex. The outer surface of the thymic lobule and interlobular septa showed adipocytes clumped together. There was a high density of NADPH-d positive cells in the medulla, without a sharp boundary in corticomedullary space. In addition to radially oriented blood vessels in the cortex, they were also found as solitary profiles with well stained walls in the medulla. Neuronal plexuses were localized in perivascular topography.
These results suggest the possibility, that NO may be utilized within the rabbit thymus.
Key words: histochemistry; NADPH-d; NO; rabbit; thymus
