    Notizen: Abstract Biological investigations have the potential to produce large volumes of data, much of which is condensed or omitted from publications, and which may not be readily accessible to researchers outside that discipline. Bringing together in a single repository information whose common thread is the Solanaceae family gives researchers a valuable, multidisciplinary tool. The SolGenes (Solanaceae) database project, a part of the USDA Plant Genome Research Program, is meant to be such a tool. The database has facilities for handling genetic and physical maps, DNA sequences, pathologies and germplasm stocks, as well as other types of information. It currently contains tomato, potato and pepper genetic maps based on a common set of probes, tomato germplasm data including wild species and stocks, autoradiogram images of distributed probes and much more. Current efforts are focused on loading images of tomato mutants, expanding the germplasm data, and setting up a gopher server. The database software (ACEDB) provides a user-friendly, graphical interface with links between logically related pieces of information, allowing the user to view data from multiple sources with just a few clicks of the mouse. The database and software are freely available to interested parties.

    Notizen: Summary Although previous studies have shown that preconditioning cannot be explained by concurrent myocardial stunning alone, it remains unclear whether reduction of contractile function by preconditioning ischemia is required for its cardioprotective effect. The present study examined whether preconditioning occurs in the absence of regional contractile dysfunction. In the first series of experiments, rabbits received two cycles of 2-min coronary occlusion separated by 5-min reperfusion, with or without dobutamine infusion (10 μg/kg/min, i.v.) commencing before the onset of ischemia. Regional thickening fraction measured by epicardial Doppler sensor was 72.8±4.7% of baseline (mean±SEM) in the untreated group and 102.9±3.1% in the dobutamine group at the end of the second cycle of ischemia/reperfusion. In the second series of the study, four groups of rabbits underwent 30-min coronary occlusion and reperfusion. The control group was untreated, and the PC group was preconditioned with two cycles of 2-min ischemia/5-min reperfusion before the 30-min ischemia. The PC-DOB group received both preconditioning and dobutamine infusion (10 μg/kg/min, i.v.), which was started 5 min before the preconditioning and continued for 19 min. The DOB group was given dobutamine infusion like the PC-DOB group, but was not preconditioned. After 72-h reperfusion, infarct size and area at risk were determined by histology and fluorescent particles, respectively. Infarct sizes in the PC and PC-DOB groups (25.0±3.4% and 22.7±3.3% of area at risk, respectively) were significantly smaller than that in the control group (48.2±2.6%). In the DOB groups, infarct size (43.5±4.0%) was similar to the control value. Infusion of dobutamine at a dose sufficient to abolish the contractile dysfunction which would have been induced by ischemic preconditioning did not attenuate the infarct size-limiting effect of preconditioning. Thus, it is unlikely that reduction of contractile function plays a permissive role in the appearance of the cardioprotective effect of preconditioning.
