Stevens, Randel J., Jeffery S. Weinert, and Nelson G. Publicover. Visualization of origins and propagation of excitation in canine gastric smooth muscle. Am. J. Physiol. 277 (Cell Physiol. 46): C448–C460, 1999.—The origin and spread of excitation were visualized with fluo 3 fluorescence in tissues isolated from canine gastric antrum. Sheets of circular muscle (5 3 6 mm) had at least 1 (30%) and...

Burgess, Don E., Tabitha A. Zimmerman, Marshall T. Wise, Sheng-Gang Li, David C. Randall, and David R. Brown. Low-frequency renal sympathetic nerve activity, arterial BP, stationary ‘‘1/f noise,’’ and the baroreflex. Am. J. Physiol. 277 (Regulatory Integrative Comp.

Thrasher, Terry N., Craig R. Keenan, and David J. Ramsay. Cardiovascular afferent signals and drinking in response to hypotension in dogs. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R795–R801, 1999.— Arterial hypotension stimulates increases in plasma arginine vasopressin (AVP), plasma renin activity (PRA), and water intake in conscious dogs. We have previously reported tha...

Ghai, H. S., and L. T. Buck. Acute reduction in whole cell conductance in anoxic turtle brain. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R887–R893, 1999.—We tested the effect of anoxia, a ‘‘mimic’’ turtle artificial cerebrospinal fluid (aCSF) consisting of high Ca21 and Mg21 concentrations and low pH and adenosine perfusions, on whole cell conductance (Gw) in turtle brain ...

Butler, David Gordon. Mecamylamine blocks the [Asp1,Val5]-ANG II-induced attenuation of salt gland activity in Pekin ducks. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R836–R842, 1999.—An intravenous injection of 2 μg of [Asp1,Val5]-ANG II attenuated fluid secretion by the nasal salt glands of Pekin ducks. Ganglionic blockade with mecamylamine stopped salt gland secretion. F...

Lapointe, Benoı̂t M., and Claude H. Côté. Anesthetics can alter subsequent in vitro assessment of contractility in slow and fast skeletal muscles of rat. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R917–R921, 1999.—Anesthetic agents can interfere with measurement of skeletal muscle contractility in vivo or in situ. Data obtained in vitro are however believed to be unaffected ...
