Synchronized videonasendoscopy and respiratory recordings were conducted in six healthy male subjects to evaluate activity of the arytenoid cartilages, true vocal folds, false vocal folds, and epiglottis during repeated trials of three breath-hold maneuvers:easy hold,inhale hard hold, andinhale/exhale hard hold. Five of the six subjects demonstrated maximal(More)
Three Shetland ponies were given a single oral dose of ground Cassia occidentalis seeds in aqueous suspension. The clinical signs observed resembled those seen in naturally occurring and experimental cases in cattle. The syndrome was characterized by an afebrile course, incoordination, recumbency and death. Elevations of blood alkaline phosphatase, CPK,(More)
BACKGROUND Spinal injury in children is rare, and poses many difficulties in management. AIMS To ascertain the prevalence of spinal injury within the paediatric trauma population, and to assess relative risks of spinal injury according to age, conscious level, injury severity score (ISS), and associated injuries. METHODS Spine injured children were(More)
Uterotrophic response in sexually immature female rats has been used to rank the relative estrogenic potencies of six resorcylic acid lactones (RALs) and to compare their activities with that of 17 beta-estradiol. On oral administration, the estrogenic potency relative to 17 beta-estradiol is as follows: 7 alpha-zearalenol, 10 times less; zeranol, 150 times(More)
White Leghorn roosters bursectomized at one day of age, splenectomized at 21 days of age, or bursectomized at one day of age and splenectomized at 21 days of age were infested with the northern fowl mite (NFM) at 22 to 23 weeks of age. No significant differences in NFM populations were observed in the bursectomized, splenectomized, bursectomized and(More)
Human erythrocytes were shown to possess a saturable uptake mechanism for 2-chloroadenosine (apparent Km 23 microM, 22 degrees). Uptake by this route was inhibited by nitrobenzylthioinosine, uridine and adenosine, but adenine had no effect. In addition, uridine caused the countertransport of 2-chloroadenosine and vice versa. 2-Chloroadenosine was also shown(More)
The initial rate of [14C]uridine transport by guinea pig erythrocytes was investigated at different temperatures. At 37, 22, and 10 degrees C the concentration dependence of uridine zero-trans influx and equilibrium exchange influx was resolved into two components; (a) a saturable component which followed simple Michaelis-Menten kinetics and which was(More)
