Objective: This study aims to explore the effect of an extract of Atractylodes lancea (A. lancea) on antibiotics-induced intestinal tract disorder and the probable therapeutic mechanisms employed by this extract to ameliorate these disorders.
Methods: Three days after acclimatization, nine male and nine female specific-pathogen-free (SPF) mice were randomly assigned into three groups: Group C (normal saline), Group M (antibiotic: cefradine + gentamicin), and Group T (antibiotic + A.
Objective: Decolorization of crude chitin from Catharsius molossus was studied in order to prepare chitosan with white color and high viscosity.
Methods: Some factors affecting decolorization such as the kind of decolorant reagent, H2O2 concentration, pH, solid-liquid ratio, temperature and other factors were studied by single factor test and orthogonal design.
Results: The best decolorization process of chitin from Catharsius molossus was as follows:treated with 15 times of 15% H2O2 at 45 degrees C.
A great deal of melanin was found in the waste alkali liquor produced by extraction of chitin from Catharsius molossus L. Discarding the lye could harm the environment and cause waste of resources. In this paper, melanin from C.

Methods: Preparation technique of chitosan was studied by orthogonal design,and properties were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), etc.
Results: Preparation techniques were as follows: demineralizing: soaked for 30 min at 80 degrees C with 1.
