OBJECTIVES To compare the effectiveness of different oral analgesics for relieving pain and distress in adults following the extraction of teeth and deep cavity preparations under local anesthesia. Methods: This randomized controlled study was conducted between November 2015 and May 2016. One hundred and twenty patients were randomly allocated to 3 groups. Forty patients were in the paracetamol...

BACKGROUND To describe a case of an accidental epidural potassium infusion leading to an acute transient spinal paralysis and cardiac symptoms and review the literature on that topic. CASE PRESENTATION We report the case of an accidental infusion of 900 mg potassium chloride 7.45% (KCl) into the epidural space, which occurred during epidural analgesia in a 74-year-old patient suffering from i...

Acute intravenous Tempol reduces mean arterial pressure (MAP) and heart rate (HR) in spontaneously hypertensive rats. We investigated the hypothesis that the antihypertensive action depends on generation of hydrogen peroxide, activation of heme oxygenase, glutathione peroxidase or potassium conductances, nitric oxide synthase, and/or the peripheral or central sympathetic nervous systems (SNSs)....

BACKGROUND Mild to moderate therapeutic hypothermia (TH) has been shown to improve survival and neurological outcome in patients resuscitated from out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF) as the presenting rhythm. This approach entails the management of physiological variables which fall outside the realm of conventional critical cardiac care. Management of serum...

We assessed the changes in arterial potassium concentration during exercise and recovery in relation to exercise tolerance in patients with impaired exercise tolerance. Sixteen patients with cardiac disease were subjected to a cardiopulmonary exercise test on a cycle ergometer. Arterial potassium and lactate concentrations were measured every minute during and after exercise, and ventilatory th...

Ionic currents of enzymatically dispersed type I and type II cells of the carotid body have been studied using the whole cell variant of the patch-clamp technique. Type II cells only have a tiny, slowly activating outward potassium current. By contrast, in every type I chemoreceptor cell studied we found (a) sodium, (b) calcium, and (c) potassium currents. (a) The sodium current has a fast acti...

Brief labeling of cells infected with simian virus 40 with tritiated uridine resulted in the incorporation of part of the label into material that was soluble in 1 M NaCl and sensitive to KOH, with a buoyant density close to that of DNA. The properties of this material suggest that it represents single-stranded nascent molecules of messenger RNA of simian virus 40 hydrogen-bonded over a small p...

40 Ar/ 39 Ar analyses were made on maruyamaite (potassium-dominant tourmaline) from tourmaline-quartz-feldspar rocks discovered within the Kumdy-Kol microdiamond deposit (Kokchetav massif, North Kazakhstan). Turmaline yielded well-defined plateau age spectra whose values coincide error - ages of 502.3±8.0, 502.2±8.0, 506.0±8.0 Ma. These are much younger than 530±2 Ma determined for high-pressur...

The concentrations of Cs and potassium in the surface layers of arable soils were analyzed in the selected region of Eastern Poland approximately 20 years after the Chernobyl power plant accident. Additionally, the occurrence of the elements in soil in the forms available for plants was determined. In relation to the total concentrations of Cs and K in the soil, cesium is found in larger quanti...

A severe limitation in studies of avian ecological energetics is the lack of an accurate, noninvasive technique for determining whole body fat storage in living birds. We explored a technique of assaying total body potassium as a predictor of lean mass (LM) and then derived fat mass (FM) by subtracting LM from total body mass. Body potassium ’ Received 15 December 1997. Accepted 3 April 1998. (...
