In recent years metabotropic glutamate receptors (mGluRs) have received considerable attention as a potential target for psychotropic drugs, but their influence on learning and memory is still unclear. The aim of the present study was to examine whether intraperitoneal (i.p.) administration of selective mGluR5 antagonist 2-methyl-6-(phenylethynyl)-pyrydine(More)
AIMS The differential diagnosis of thyroid nodules in routine practice can be problemmatic for both pathologists and clinicians. Effective treatment requires a determination of the biological nature of the lesions. For this reason, ancilliary diagnostic markers along with histological examination of the nodules may be useful. The objective of this study was(More)
A decrease of external pH during rhythmic excitation of the nerve of frog and squid was investigated. The level of pH was dependent on frequency excitation, concentration of sodium potassium and hydrogen ions was changed after ouabain, 2,4-dinitrophenol, tetraethylammonium and tetrodotoxin effect. The mechanism of proton transport was discussed in relation(More)
The activation mechanism of Na,K-ATPase in nerve fibres after rhythmic excitation was studied. 3H-ouabain binding to a nerve was found to depend on the frequency of rhythmic excitation. The maximum of 3H-ouabain binding to a nerve crab was at 10 imp/sec. Rhythmic excitation was found not to change Na,K-ATPase affinity to ouabain, but appeared to increase(More)
