Abstract Background: Asthma is one of the most common childhood diseases and the first cause of school absentness and third cause of hospitalization in the children under 15 years. The goal of this study was to assess the effect of symptoms-based “written action plan” on frequency of emergency department visits and school absentness in children with the age of 7-18 years. Materials and methods:...
The purpose of these experiments was to examine the effects of norepinephrine and propranolol on distal Purkinje fibers of the canine heart. Previous studies have indicated that action potential duration is normally greatest in distal Purkinje fibers 3—4 mm from the Purkinje-muscle junction. In such preparations, premature beats initiated either proximal or distal to the area of maximal action ...
Ion channels are responsible for control of cell function in excitable tissues such as heart and brain and also in organs and tissues traditionally thought to be non- excitable including liver and epithelium. In the present research, the effect of lead (Pb2+) on Ca2+ -dependent action potential and currents was studied in F77 neuronal soma membrane of Helix aspersa. For this purpose, action pot...
