[Preganglionic parasympathetic innervation of the intact and partially denervated rat stomach].
The preganglionic parasympathetic innervation of normal and vagotomized rat stomach have been investigated by the horseradish peroxidase (HRP) technique. After the HRP injection into the antrum and fundus muscles the labelled cells were revealed in nuclei dorsalis nervi vagi bilaterally, but preferentially in the left nucleus. The most numerous labelled cells were observed after injection into the region of the curvatura minor. When HRP was injected into the vagotomized stomach one, three, four and six months after the surgery procedures the labelled cells in the nuclei nervi vagi were not revealed. Mechanisms of regeneration of nervi vagi efferents and normalization of the stomach activity are discussed.
