Histochemical study on the nerve endings in the lung of Rattus rattus rufescens and Francolinus pondicerianus.

Presence and the relation of the nerve endings with associated structures in the lund of Rattus rattus rufescens (Indian black rat) and Francolinus pondicerianus (grey partridge or safed teeter) has been studied by cholinesterase technique. Dot, plate, and Vater pacini Corpuscles like nerve endings in the lung of Rattus and dot, and bulb like nerve endings with axis cylinder covered with myelinated sheath in the lung of Francolinus were recorded. The nerve endings were AChE-positive.
