Entrapment of Lactobacillus acidophilus into alginate beads for the effective treatment of cold restraint stress induced gastric ulcer

Author affiliations

Abstract

Lactobacillus acidophilus (LAB) loaded alginate floating beads (FBs) were developed with an intent to (i) preserve their viability during manufacture and upon exposure to adverse physiological conditions existing in the stomach, (ii) achieve an increased stay of the system in the stomach for improved pharmacodynamics and to provide for their effective establishment within the gastric mucosa. In vitro characterization of developed beads was performed in terms of entrapment efficiency, buoyancy, and surface as well as cross sectional morphology and viability studies of LAB in a gastric environment. The developed system was evaluated and was found to be significantly better in an experimental model of cold restraint stress (CRS) induced gastric ulcer model in terms of ulcer index, hemorrhagic streak length, histopathological and biochemical markers and their cross talk with reactive oxygen/nitrogen species. The present study emphasizes the advantages and future potential of probiotic loaded FBs in gastric disorders.
