Dose-response curves of vasorelaxants: computerized calculation of combination effects using the example of nicorandil
Dosiswirkungsbeziehung - Nitroprussid
Journal of Clinical and Basic Cardiology 1999; 2 (1): 96-98
Cumulative dose-response curves (DRCs) of nitroprusside in the absence (open symbol) and presence of 3-20 micromol/L nicorandil (filled symbols), a) in the absence, b) in the presence of 1 micromol/L glibenclamide. The symbols and bars
represent experimental mean values from 12 experiments and 95 % CI. Experimental DRCs are shown by solid lines, theoretical DRCs by dashed lines (dose-additivity) and dotted lines independence). For graphical clarity, the following theoretical curves are shown in a) bands of 95 % CI with upper and lower boundary of dose-additive
combinations of nitroprusside in the presence of 3 and 20 micromol/L nicorandil, curve of mean independent effect of nitroprusside in the presence of 20 micromol/L nicorandil, b) means of dose-additive combinations of nitroprusside with 3, 10, and 20 micromol/L nicorandil. The effects of nicorandil alone are shown on the y-axis. Significant deviation from dose-additivity is indicated by asterics. Keywords: Diagramm,

Work noise as a risk factor in myocardial infarction
Lärmwirkung
Journal of Clinical and Basic Cardiology 1999; 2 (1): 64-68
Relative risk (RR) of MI in men (and 95 % confidence intervals) by work noise category. Work noise was assessed by subjective loudness comparison with typical noise sources (1+2: refrigerator + typewriter, 3: electric lawn-mower, 4: electric drill, 5: road drill). Relative risk of MI (ICD 410) was adjusted for covariates (smoking, body mass index, age, social class, education, marital status, shift work, housing area) using logistic analysis.

Some observations and pathophysiological considerations concerning KATP-channels and coronary heart disease
Autopräkonditionierung - Myokardinfarkt
Journal of Clinical and Basic Cardiology 1999; 2 (1): 15-18
Phenomenon of autopreconditioning. During the early phase of acute myocardial infarction, various parameters of ischaemia are subject to changes: ST-elevation, CK-MB, myoglobin as well as ANP rise and fall in an episodic manner. They reflect alternating phases of coronary artery occlusion and spontaneous reperfusion. PTCA, in contrast, only causes one peak in the ANPconcentration curve, as we see only one occlusion and one reperfusion (see figure 4). Keywords: autopreconditioning,

ANP-Freisetzung nach Ischämie
Journal of Clinical and Basic Cardiology 1999; 2 (1): 15-18
Liberation of atrionatriuretic peptide after a short ischaemic episode (PTCA of LAD) in patients with coronary heart disease. The inset shows the concentrations of ANP in the coronary sinus. The curve with open symbols shows the ANP-concentrations of patients from the antecubital vene. The fast rise of ANP leads to peripheral vasodilation, coronary dilatation and elimination of volume by strong diuresis. These mechanisms are cardioprotective by reducing pre- and afterload.

Guinea pig papillary muscle. Typical results when measuring K+ during an ischaemic episode. A. Experiment performed using an electrode bevelled with a 45° angle pushed too deeply into the preparation - penetrating approximately two or three layers of myocardial cells. Right handside panel: lack of effect of glibenclamide upon ischaemic K+ efflux in the same experiment, when microelectrode pushed too deeply into the tissue. B. Ideal experimental conditions: flat-tipped surface
microelectrode gently touching the preparation like in Figure 2. Glibenclamide (100 microM) prevents early ischaemia-induced K+ efflux. Keywords: Arteria coronaria,

Simplified diagram of different microelectrode tips during simulated ischaemia. Hatched area represents paraffin oil (P.o.), area underneath, marked with oval rings, represents myocardial or smooth muscle tissue (T). Between tissue and P.o. one can see the artificially created reduced extra-cellular space (ARECS). a. Electrode tip bevelled in a 45° angle not yielding ideal contact with the tissue surface, thus making contact with the paraffin oil. Under these conditions the hydrophobic carrier will instantly escape from the tip and the electrode does not give further readings. b. Elec-trode tip bevelled in a 45° angle pushed too deeply into the tissue causing cell damage. Cells will be
either damaged or destroyed causing a constant leak of K+(K+ ions represented by stippling) into the ARECS which, in turn, leads to faulty measurements: instead of ischaemia-induced K+ efflux caused by changed K+ conductance of the membrane the electrode measures changes resulting from damaged cells (c.f. Fig. 3). c. Electrode tip bevelled in a 90° angle (flat tip) ideally positioned in the ARECS. Only under these circumstances correct measurements of transmembrane K+ efflux induced by ischaemia are possible (c.f. Fig. 3). d. Ideally bevelled surface microelectrode, impaled too deeply into the tissue. Stippling represents K+ ions leaking from damaged tissue - readings will be misleading. e. Too fine-tipped microelectrode, pushed too deeply into the tissue. Leaking K+ from the damaged tissue like in b and d, represented by stippling and small arrows. Keywords: Arteria coronaria,

Experimental assembly used for simulating ischaemia. Fig. redrawn from Gasser & Vaughan-Jones (1990). Schematic diagram of perfusion chamber. Ion-selective microelectrode (in our experiments e.g. Na+, pH, K+- selective microelectrode) pressed gently on the surface of a pig coronary artery strip and recording specific ion concentration changes during ischaemia. Preparation is laid across four supports (micropins, 100 µm in diameter) and pinned on one end and attached to a force transducer at the other. Also shown are two electrodes for field Stimulation. The diagram illustrates an episode of simulated ischaemia, with the preparation immersed almost completely in a stationary pool of paraffin oil (heavy stippling) while perfusion of warm (37 °C) Tyrode (light stippling) continues at the base of the chamber. Dashed lines represent ligated areas as described in the Methods. Keywords: Arteria coronaria,
