Pulmonary endocrine cells and the pulmonary circulation in various species in the Himalaya

The numbers, morphology and distribution of pulmonary endocrine cells in goats, sheep, and the yak and its interbreeds were demonstrated by means of the peroxidase-antiperoxidase technique using a polyclonal antiserum to neuron-specific enolase. The animals came from two different locations and altitudes, Srinagar, Kashmir at 1250 m and Sakti in Ladakh, 4500 m. The presence of immuno-reactive cells was demonstrated in all animals but was related to species and not to the altitude of residence.
