Artif Cells Nanomed Biotechnol. 2017 Aug;45(5):981-989. doi: 10.1080/21691401.2016.1198363. Epub 2016 Jun 20.

Abstract

Inflammatory bowel disease (IBD) is an inflammatory disorder of the digestive tract reported to be primarily caused by oxidative stress. In this study, alginate encapsulated nanoceramic carriers were designed to deliver acid labile antioxidant enzyme catalase orally. Complete system was characterized for size, loading efficiency, in vitro antioxidant assay and in vitro release. The prepared nanoceramic system was found to be spherical with diameter of 925 ± 6.81 nm. The in vitro release data followed the Higuchi model in acidic buffer whereas in alkaline pH sustained and almost first order release of enzyme was observed up to 6 h.

Keywords: Antioxidant enzymes; IBD; catalase; hydroxyapatite; nanoceramic core.
