[Protective effects of total saponins of on ulcerative colitis induced by TNBS in rats and its mechanism].

To study the protective effects and mechanisms of total saponins of (TSC) on ulcerative colitis in rats. Fifty male Wistar rats were randomly divided into 5 groups: control group, model group, salazosulfadiazine (SASP) positive control group (0.3 g/kg), TSC high- and low-dose experimental groups(1.

A NiFe Alloy Reduced on Graphene Oxide for Electrochemical Nonenzymatic Glucose Sensing.

A NiFe alloy nanoparticle/graphene oxide hybrid (NiFe/GO) was prepared for electrochemical glucose sensing. The as-prepared NiFe/GO hybrid was characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results indicated that NiFe alloy nanoparticles can be successfully deposited on GO.
