Analysis of the mechanisms responsible for altered smooth muscle activity and endothelial and epithelial function, elicited by detrimental action of reactive oxygen species produced during pathological stages (e.g. ischaemia/reperfusion, diabetes mellitus, hypertension, arthritis). By applying techniques of pharmacology and biochemistry, the modulatory action of some drugs with antioxidant and scavenging properties (e.g. pyridoindols, natural products, etc.) on the ROS-induced injury of smooth muscle functions is determined and characterised.
Cardiovascular pharmacology, cell signalling mechanisms in myocardial and vascular smooth muscle cells and in compromised myocardial tisues, use of animal experimental models.
Study of the action of compounds affecting a generation and/or the action of reactive oxygen species on central nervous tissue damaged due to oxidative stress. The main aim has been pharmacological protection of the nervous system against oxidative stress occurring in some acute and chronic neurological diseases. The problem is being analyzed on receptor, biochemical, cellular, tissue, and whole animal level.

Experimental models of mesenteric ischaemia/reperfusion and streptozotocine-induced diabetes in rats. Isometric measurement of basal and pharmacologically-elicited vascular smooth muscle mechanical activity. Biochemical determination of antioxidative and diabetic status of animal organism.
Biochemical assays. Animal experimental models of myocardial infarction and experimental therapy with different drugs. Experimental model of brain ischaemia in vitro (hippocampal slices exposed to hypoxia with hypoglycaemia). Experimental model of trimethyltin-induced neurodegeneration: an early and late stage of neuronal damage. Electrophysiological analyses (neurotransmission, excitability, synaptic plasticity) of functional damage in hippocampal slices due to ischemia in vitro or neurodegeneration. Study of biochemical markers of oxidative damage in nervous tissue (determination of thiobarbituric reacting substances; detection of protein carbonyls; enzyme and metabolic intermediate assays, etc.).
