Contraction of isolated smooth-muscle cells--structural changes.
The contraction of isolated smooth-muscle cells has been correlated with evagination of the cell membrane, a marked change in myofilament orientation, and a decrease in cellular volume. Both localized and full contractions have been elicited in the same cell by varying the intensity of electrical stimulation. These results may be explained by a model of the smooth-muscle cell in which the contr...
متن کاملDynamics of smooth muscle contraction
Photolysis of caged calcium (Nitr5, Calbiochem®) can be used to studycalcium dependent processes such as excitation-contraction coupling andmuscular mechanics. Expensive high energy light sources are routinely used forUV light exposure; this study describes an alternative low cost Xenon flash unitconstmcted in our laboratOlY. A 300 J short arc Xenon flash lamp (Heimarl1l®)wa...
متن کاملRELMα can cause contraction of rat aortic smooth muscle cells.
OBJECTIVE This study aims to observe the contraction role of RELMα in rat aortic smooth muscle cells and explore its mechanism. METHODS Rat aortas smooth muscle cells were cultivated using tissue explants method. They were divided into 5 groups. A: Control group; B: 1×10(-7) mol/L ANGII group; C: 1×10(-8) mol/L RELMα group; D: 2×10(-8) mol/L RELMα group; E: 4×10(-8) mol/L RELMα group. The tho...
متن کاملCa-induced contraction of cat esophageal circular smooth muscle cells
Cao, W., Q. Chen, U. D. Sohn, N. Kim, M. T. Kirber, K. M. Harnett, J. Behar, and P. Biancani. Ca-induced contraction of cat esophageal circular smooth muscle cells. Am J Physiol Cell Physiol 280: C980–C992, 2001.— ACh-induced contraction of esophageal circular muscle (ESO) depends on Ca influx and activation of protein kinase Ce (PKCe). PKCe, however, is known to be Ca independent. To determine...
متن کاملPotentiation of smooth muscle contraction by adrenal steroids.
F Bhadrakom, 1 and Helmer have employed spirally cut strips of rabbit aorta in a bioassay method for estimation of urinary levels of catechol amines. In attempting to use this method for determination of adrenal venous plasma levels of epinephrine and norepinephrine, the possibility arose that adrenal steroids might alter the contraction of rabbit aortic smooth muscle produced by these eatechol...
