The role of propagated activity in the responses to agonist drugs was studied for the rat uterus and vas deferens. Hypertonic solutions were used to inhibit propagation of activity by shrinking cells. Tissue weight was used to indicate cell volume. Hypertonic solutions after 10 min caused weight loss and reduced the size of contractions in response to submaximal doses of drugs, to KCl, and to e...
Results |TheLTL (expressed in the telomere repeat copynumber to the single gene copy number ratio) remained unchanged during and after the OC intake. In contrast, the LTL doubled while taking PioFluMet and returned to baseline after thePioFluMet intakewasstopped(Figure).TheLTLchanges across treatment groupsduring 18months related inversely to fasting insulinemia, body fat fractionbydual energy ...
To assess nutrient sensitivity in a population of gastric load-sensitive vagal afferents, their neurophysiological activity was examined in anesthetized rats with inflated pyloric cuffs after gastric infusion of a range of volumes of nutrient and equiosmotic saline solutions. Responses to physiological saline loads (1, 2, 4, and 8 ml) were compared with responses elicited by the same volume ran...
To evaluate the protoscolicidal effects of various concentrations of hypertonic glucose, live protoscolices of sheep were exposed to 10%, 15%, 25% and 50% glucose solutions. Cetrimide (0.5%), silver nitrate (0.5%) and hypertonic saline (20%) were used as positive controls, while physiological saline was used as a negative control. After 1, 2 and 5 min, the protoscolicidal effects were determine...
BACKGROUND It is an inherent assumption in randomised controlled trials that the drug effect can be estimated by subtracting the response during placebo from the response during active drug treatment. OBJECTIVE To test the assumption of additivity. The primary hypothesis was that the total treatment effect is smaller than the sum of the drug effect and the placebo effect. The secondary hypoth...
BACKGROUND The infusion of small volumes of hypertonic saline solution or hypertonic saline plus dextran 70 is remarkably effective in restoring adequate hemodynamic conditions after hypovolemic shock. This prospective double-blind study compares the immediate hemodynamic effects of a bolus infusion of 7.5% NaCl or 7.5% NaCl plus 6% dextran 70 (both 2400 mOsm/L) in severe hypovolemia. METHODS...
Hypertonic saline inhalation has become a cornerstone in the treatment of cystic fibrosis (CF), but its effect on CF mucus is still not understood. In CF, mucus stagnates in the airways, causing mucus plugging, and forming a substrate for bacterial invasion. Using horizontal Ussing-type chambers to allow easy access to the tissue, we have recently shown that the small intestinal mucus of CF mic...
INTRODUCTION Reliable characterization of a hypertrophic scar (HTS) is integral to epidemiologic studies designed to identify clinical and genetic risk factors for HTS. The Vancouver Scar Scale (VSS) has been widely used for this purpose; however, no publication has defined what score on this scale corresponds to a clinical diagnosis of HTS. METHODS In a survey of 1000 burn care providers, we...
Hypertonic solutions play an important role in the treatment of tissue edema. Following the induction of experimental vasogenic brain edema by occlusion of the common carotid arteries in eight rabbits, the effect of hypertonic lactated Ringer's solution (subjects), vs. isotonic lactated Ringer's solution (control), was studied on blood pressure, electrolyte (sodium, potassium, and calcium) ...
