Example 6
SPF female ICR mice were obtained at 3 weeks of age from Taconic Farms (Hudson, NY), and used for the experiments after one-week acclimation. Mice were housed at the Isolation Unit of the Central Animal Facility (University of Guelph) in a temperature controlled environment with a 12 h light/dark cycle. Animal care was provided in accordance with the animal utilization protocol no. 04R030 (University of Guelph) and the Guide to the Care and Use of Experimental Animals (1). Mice were fed sterilized solid rodent chow and water. When needed, water was supplemented with Amp and Km at a concentration of 400 mg L−1 and 200 mg L−1, respectively. Each mouse was assessed daily for weight, body temperature, signs of dehydration, posture and alertness.
Example 26
33 ICR mice were randomly divided into 11 groups, i.e. normal saline group, 1.8 mg/kg dexamethasone acetate group (Dex), CK, IB, IC, ID, IVA, IH, IJ, IK and IL were respectively given 225 mg/kg. The mice were intragastric administration for 6 consecutive days, fasting was started at about 8:00 in the morning on the sixth day, and blood glucose in caudal vein was measured at about 4:00 in the next day.
Blood glucose data showed that compared with the blank control group, dexamethasone could increase blood glucose in mice, while no blood glucose related changes were caused by CK and GR derivatives.
