Abstract:
Objective To explore the damage of intestinal mucosal barrier caused by vinegar retention enema, and compare the degree of injury in intestinal mucosal barrier between isotonic vinegar and traditional hypertonic vinegar treat-ment. Methods Sixteen adult rabbits were randomly divided into two groups. The solution of vinegar mixed with normal so-dium was given to hypertonic group. Isotonic group was administered with isosmotic solution made of vinegar and double dis-tilled water, with the same volume fraction and pH as hypertonic group. Then two different osmosis solutions were given as enema solution to rabbits under the same condition. Finally, damages of intestinal mucosa were observed by light microscope and transmission electron microscope (TEM) in two groups. Results It was observed that injuries of rectum and distal part of colon were more severe in hypertonic group than those of isotonic group through light microscope. Besides, cell structures were morphologically normal, with in-line microvilli and intact tight junction in isotonic group. In hypertonic group, microvil-li of intestinal cells decreased or disappeared, the cell junction is widened, and cell apoptosis and necrosis were found through TEM. Conclusion Results showed that isotonic vinegar had less damage to mucosa. Consequently, isotonic vinegar can be considered as enema solution for hepatic encephalopathy to avoid damage by osmosis in clinic.
