Deverall, P. B., Muss, D. C., Macartney, F. J., and Settle, J. D. (1973). Thorax, 28, 756761. Osmolal balance after open intracardiac operations in children. Changes in plasma osmolality, urine osmolality, urine volume, total osmolal output, and free osmolal output have been studied in children between 2 and 10 years of age. All underwent elective open intracardiac operations. Plasma hypo-osmol...

Previous studies suggest that urine-borne pheromones play an important role in lobster agonistic and sexual behaviour. This paper investigates the pattern of urine release in catheterised, but otherwise freely moving, adult lobsters with respect to feeding, social and non-social activities. Lobsters on average released 4.1 ml (1 % of body mass) of urine over a 12 h period; this more than double...

The sodium sensitivity of the carotid sinus baroreceptor reflex was demonstrated in anesthetized cats. Decreases in carotid perfusate sodium concentration |Na ] o of 5% and 12.5% attenuated the depressor response to increased carotid sinus pressure. At constant sinus pressure, increases in systemic pressure and heart rate were produced when the carotid perfusate |Na]o was switched from 145 mM (...

PURPOSE The development of micturition in mice has been poorly studied because of the minute urine volume voided per micturition. We characterized development of the micturition pattern in young mice. MATERIALS AND METHODS Micturition in young and adult C57BL/6 strain mice, including 5 males and 4 females at age 3 weeks immediately after weaning, and 5 of each gender at ages 9 to 10 weeks, re...

OBJECTIVE The purpose of the study was to evaluate the efficacy and safety of botulinum A toxin in the treatment of detrusor sphincter dyssynergia in multiple sclerosis patients. METHODS This was a multicentre, placebo controlled, randomised, double blind study. Patients with chronic urinary retention were included if they had post-voiding residual urine volume between 100 and 500 ml. They re...

Purpose: Hypohydration and hyperhydration are significant disorders of fluid metabolism in endurance performance; however, little relevant data exist regarding multi-stage endurance activities. The aim of the present study was to examine the effect of running seven marathons in 7 consecutive days on selected anthropometric, hematological and biochemical characteristics with an emphasis on hydra...

urinary 1-hydroxypyrene is frequently used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons. in this study, solid phase extraction was appropriately conditioned with regard to sample ph, sample concentration, loading flow rate, elution solvent, washing solvent, sample volume and sorbent mass. octadecyl silica cartridge (c18) was used as ...

The aqueous and ethanolic extract of leaves of Coleus aromaticus was evaluated for diuretic activity. Both extracts were evaluated by determination of urine volume and electrolyte concentration in albino rats. Results revealed that both the aqueous and ethanolic extract at dose 500mgl kg showed significant diuretic activity by increasing the total volume of urine and concentration electrolyte. ...

Nocturia is a common disease in patients with type 2 diabetes mellitus that can reduce the quality of life. Sodium glucose co-transporter (SGLT2) inhibitors increase urine volume and are often discontinued when polyuria occurs, although tofogliflozin, which has short half-life blood, may improve nocturia by managing hyperglycemia hypertension, without aggravating nocturia. As excessive sodium i...

To study the relationship between vasopressin and the renal kallikrein-kinin system we measured the rate of excretion of kinins into the urine of anesthetized rats during conditions of increased and decreased vasopressin level. The excretion of immunoreactive kinins in Brattleboro rats with hereditary diabetes insipidus (DI) (24 +/- 3 pg min-1 kg-1) was lower than in the control Long Evans (LE)...
