Adult Studies: In a double-blind study of three different dosing regimens of ZOFRAN Injection, 0.015 mg/kg, 0.15 mg/kg, and 0.30 mg/kg, each given three times during the course of cancer chemotherapy, the 0.15-mg/kg dosing regimen was more effective than the 0.015-mg/kg dosing regimen.
Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward. Earthworms use a similar mechanism to drive their locomotion, and some modern machinery imitates this design.
1 As a result of segmentation; a process by which some physical digestion occurs in the small intestine, the chime sloshes back and forth between segments of the small intestine that form when bands of circular muscle briefly contract.2  A helpful animation that outlines the process of peristalsis and segmentation. This image illustrates the segmentation of the chyme that occurs within the small intestine of the digestive tract. 2  Segmentation is the process of mixing the food contents in the digestive tract to create a more uniform mixture throughout.
