Antiobese effects of capsaicin-chitosan microsphere (CCMS) in obese rats induced by high fat diet.

Chitosan (CTS) and capsaicin (CAP) are two kinds of effective ingredients for antiobesity, which are extracted from crab shells and Capsicum annuum. However, the strong taste of CAP makes it difficult to consume, and the antiobesity ability of CTS is limited. In this study, we prepared capsaicin-chitosan microspheres (CCMSs) by ion-cross-linking and spray drying and examined the antiobesity ability of CCMSs in obese rats.

The preparation of capsaicin-chitosan microspheres (CCMS) enteric coated tablets.

This study aimed to research the preparation and content determination of capsaicin-chitosan microspheres (CCMS) enteric coated tablets. The core tablets were prepared with the method of wet granulation. Nine formulae were designed to determine the optimal formula of the core tablet.

Preparation of Chitosan and Water-Soluble Chitosan Microspheres via Spray-Drying Method to Lower Blood Lipids in Rats Fed with High-Fat Diets.

This experiment aimed to investigate the effects of the chitosan (CTS) and water-soluble chitosan (WSC) microspheres on plasma lipids in male Sprague-Dawley rats fed with high-fat diets. CTS microspheres and WSC microspheres were prepared by the spray-drying technique. Scanning electron microscopy (SEM) micrographs showed that the microspheres were nearly spherical in shape.

Effects of chitosan and water-soluble chitosan micro- and nanoparticles in obese rats fed a high-fat diet.

Purpose: This study determined the effects of chitosan (CTS) and water-soluble chitosan (WSC) microparticles (MPs) and nanoparticles (NPs) in rats with high-fat diet-induced obesity.

Methods: THE RATS WERE RANDOMLY SEPARATED INTO EIGHT GROUPS: a normal diet group (the blank control), a high-fat emulsion group (the negative control), CTS and WSC control groups, CTS-MP and WSC-MP groups, and CTS-NP and WSC-NP groups. All groups (except the blank control group) were fed the high-fat diet for 4 weeks to establish the obesity model.

Hypolipidemic effects of chitosan nanoparticles in hyperlipidemia rats induced by high fat diet.

The aim of this study was to investigate the hypolipidemic effects of chitosan nanoparticles(CTS-NP) preparations with ionotropic gelation, rotary evaporation, and spray-drying technique. Male SD (Sprague-Dawley) rats were separated into five groups, a normal diet group, a high fat emulsions group, a CTS control group and CTS-NP groups treated with two different doses of CTS-NP. The nanoparticles were spherical in shape and had a smooth surface.
