[Mechanical properties of the small intestine of rats in the normal state and after disturbed parasympathetic innervation].
In intact and vagotomized (in 14 and 30 days after the operation) rats by means of the dynamometric method values of maximal load and relative maximum elongation of the proximal and middle areas of the small intestine (SI) have been determined in vitro. Dependence of relative elongation of the SI fragments on the load applied has been investigated. The proximal part of the SI is the most firm to tearing in comparison to the middle one. Bilateral subdiaphragmatic+ truncal vagotomy results in an increased firmness to tearing and in relative maximal elongation of the SI proximal part in 14 days and in decrease of the former parameter in the same SI part in 30 days.
