Distribution and density of noradrenergic and acetylcholinesterase-positive nerves in the uterus of the Japanese long-fingered bat, Miniopterus schreibersii fuliginosus, during the immature period

Abstract

The distribution and density of noradrenergic (NA) and acetylcholinesterase-positive (AChE) nerves in the uterus of the young Japanese long-fingered bat were investigated using specific immunohistochemical and histochemical techniques. This species has an unusual reproductive mechanism during the immature period. An abundant number of NA and AChE nerves were found to be associated with blood vessels and smooth muscles in the myometrium. In addition, a number of AChE nerves ran in close association to the endometrium. These findings must be considered in relation to an improvement of the structure and function of the uterus of the bat as it progresses towards sexual maturity.
