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.
Peristalsis. a wavelike contraction that propels the contents of tubular organs, for example, the intestine, stomach, and ureters, caudally in animals or in a downward direction in man.Peristalsis is the result of many coordinated contractions of the longitudinal and transverse muscles in the walls of a tubular organ.A single peristaltic wave takes the form of a circular constriction around the lumen that moves along the length of the organ.eristalsis is the result of many coordinated contractions of the longitudinal and transverse muscles in the walls of a tubular organ.
