[Effect of intravascular laser irradiation of blood on the status of the adrenergic and cholinergic structures of the small intestine in experimental peritonitis].
In the experiment performed on 60 mongrel dogs the effect of intravascular laser radiation of blood (ILRB) to adrenergic and cholinergic fibers of the small intestine has been studied at treatment of experimental generalized suppurative peritonitis. At treatment of the experimental peritonitis by means of traditional method only one month after its termination a positive reaction to acetylcholinesterase (AChE) is noted, structural organization of cholinergic fibers corresponds to the norm, and density of their plexuses increases. Application of ILRB at treatment of the experimental peritonitis facilitates to increasing density of the cholinergic fibers already on the 21st day after termination of the treatment; their AChE increases essentially, their structural organization corresponds to the norm. In cytoplasm of neurons of the muscular-intestinal plexus a positive reaction to AChE is revealed; this demonstrates their increased functional activity. The small intestine adrenergic apparatus at peritonitis undergoes less manifested structural-chemical alterations. After termination of treatment by means of traditional methods it corresponds to the norm on the 7th day, and after ILBR treatment----on the 3d day. Thus, application of ILBR in treatment of the experimental peritonitis enhances the development of regenerative processes in adrenal and cholinergic structures of the small intestine, facilitates a more manifested demonstration of compensatory-reparative possibilities of the organism.
