We have investigated the physiological role of the "rapidly activating" delayed rectifier K+ current (IKr) in pacemaker activity in isolated sinoatrial node (SAN) myocytes and the expression of mouse ether-a-go-go (mERG) genes in the adult mouse SAN. In isolated, voltage-clamped SAN cells, outward currents evoked by depolarizing steps (greater than -40 mV)(More)
We report an endocrine emergency of a 52-year-old woman with chronic anterior-pituitary failure of autoimmune origin who developed hypopituitary crisis with coma and severe hypotension provoked by an intercurrent bronchopneumonia. At admission to the ICU hypopituitarism had not been diagnosed and only Hashimoto's thyroiditis with thyroid replacement therapy(More)
In this randomized, double-blind controlled study we compared the effect of parenteralnutrition with two different amino acid solutions on the plasma concentration of amino acids in 27 patients with acute renal failure. Fourteen patients received the new dipeptide-containing (glycyl-tyrosine) amino acid solution (AADI) in combination with glucose (60%) and(More)
PURPOSE To present a rare case of abscess formation around a covered stent in the superficial femoral artery. METHODS AND RESULTS Two weeks after balloon dilation of a left superficial femoral artery (SFA) occlusion, during which a Hemobahn covered stent had been placed to treat dissection, a 77-year-old nondiabetic male developed intolerable pain and(More)
This study was performed to evaluate the acute effects of two anthracycline derivatives, doxorubicin and 4′O-tetrahydropyranyl-doxorubicin [(THP)-doxorubicin], on the conduction intervals, heart rate and refractoriness of isolated spontaneously beating guinea-pig hearts using a high-resolution ECG recording technique (SST-ECG). Doxorubicin as well as(More)
The clinical spectrum of acute pancreatitis ranges from mild, self-limiting disease of fulminant illness that may rapidly lead to multiple organ failure and death. To identify factors associated with a subsequent severe course and/or high mortality we investigated retrospectively 91 patients admitted to the medical intensive care unit (ICU) with acute(More)
Objective: To investigate the role of activated leukocytes in acute pancreatitis, we measured soluble receptors of tumour necrosis factor alpha (sTNFR, p60 subtype) in plasma and evaluated the association of sTNFR with the clinical severity of the disease. Design: Prospective, descriptive study. Setting: A medical intensive care unit (ICU) in a university(More)
BACKGROUND The role of caffeine in cardiovascular disease is controversial. Most of its pharmacologic actions are attributed to its role as an adenosine antagonist. Adenosine is one of the most important endogenous vasodilatative substances and is released under ischemic conditions, for example, in the skeletal muscle of patients with peripheral arterial(More)
BACKGROUND The vasoactive effect of nicorandil on coronary arteries is well known. Nicorandil exerts its vasodilatory effect through a dual mechanism of action: involving on the one hand cyclic guanosine monophosphate (c GMP) as a nitrovasodilatator, and on the other hand, acting as a potassium channel opener. OBJECTIVE To address the question if(More)
Negative chronotropic and dromotropic effects of adenosine seem to be responsible for its antiarrhythmic action on supraventricular tachyarrhythmias. To further characterize the effects of adenosine on supraventricular arrhythmias heart rate, conduction, refractoriness, the time to steady-state of AV-nodal conduction slowing and of sinus rate reduction were(More)
