Methotrexate (MTX) conjugates with poly[Lys(DL-Alam)] based polymeric polypeptides are efficient against Leishmania donovani parasite infection, but the mechanism of the effect is not known yet. We prepared therefore the 5(6)-carboxyfluorescein (Cf) labeled oligopeptide [Cf-K(AaAa)] (a: D-alanine, A: L-alanine) and the corresponding MTX conjugates(More)
Panic agoraphobic subjects constantly struggle with the accurate registration of everyday space-time dimension. They are hindered in the exploration of their surroundings by constant self-directed attention. In our investigations we examined whether during experimental goal-directed locomotion orientation insecurity would appear. The accuracy of(More)
Inhibitors of nitric oxide (NO) synthase inhibit nerve-mediated non-adrenergic, non-cholinergic (NANC) smooth muscle relaxation in the gastrointestinal tract. In this study, the effect of a NO synthase inhibitor, NG-nitro-L-arginine, was examined on the tetrodotoxin-sensitive NANC contractile response of the rat isolated ileal myenteric plexus-longitudinal(More)
The possible mediating role of calcitonin gene-related peptide (CGRP) in the effects of capsaicin in the guinea-pig ileum has been investigated by means of the CGRP antagonist hCGRP(8-37). Submaximal longitudinal muscle relaxation of the histamine-precontracted ileum evoked by rat CGRP (3 nM) or capsaicin (1 microM) was reversed by hCGRP(8-37) (1.5 microM),(More)
245 records of 178 multiple sclerotic patients were assessed from 110 EEG-parameters and 18 clinical points of view. According to the special code the data were stored on cards and later statistically evaluated. The following conclusions were made: 1. 64% of all records were abnormal. 2. The frequency of bilateral and generalized abnormalities was(More)
