A new COMT inhibitor, nitecapone (OR-462) or clorgyline, a MAO-A inhibitor, was infused into the 3rd brain ventricle (i.c.v.) of conscious male rats. None of the enzyme inhibitors given alone alter hypothalamic or striatal levels of L-dopa, dopamine or their metabolites. Most of the rats were pretreated with levodopa/carbidopa (LD/CD, 15/30 mg kg-1(More)
Male Wistar rats were divided in free choice conditions into heavy-drinkers consuming greater than 3.5 g/kg of ethanol daily (HD), and light-drinkers consuming less than 2.0 g/kg/day (LD). Subsequent 30 day intragastric administration of 25% ethanol (8-11 g/kg/day) caused an increase in permeability of the BBB to 14C-tyrosine, 14C-tryptophan and 14C-DOPA at(More)
This study deals with the karyotype of the flathead sculpin Megalocottus platycephalus platycephalus (Pallas, 1814) (family Cottidae) from Odyan Bay of the Sea of Okhotsk. The karyotype is stable: 2n = 42 (2 metacentric, 2 submeta-subtelocentric, 30 subtelocentric, and 8 acrocentric chromosomes), NF = 44 + 2. The nucleolar organizers (NOs) were identified(More)
We studied effects of anxiogenic and anxiolytic compounds on the electric self-stimulation of the medial fore-brain bundle in male rats to find out if there is a link between reward and anxiety-related behaviours. The cholecystokinin agonist, caerulein (25-100 micrograms/kg) and the 5-HT agonist 1-(3-chlorophenyl)piperazine (0.2-1 mg/kg) dose-dependently(More)
It has been shown that alcohol-motivated Wistar female rats after 10 days of repeated ethanol administration have a decreased cold- or TRH-stimulated TSH level in the blood serum under physical dependence and abstinence. There were no changes of TSH secretion in animals non-motivated to alcohol. Acetaldehyde inhibited significantly the TSH cold-response but(More)
A 36 kDa protein was isolated from the sera of patients with ovarian cancer and rabbit antisera to this protein were prepared. Precipitation test with these antisera detected an antigen with electrophoretic mobility corresponding to alpha-1-globulins and molecular weight of 36 kDa. Direct comparison of precipitating test systems showed that this antigen is(More)
Immunoenzymatic method for the determination of new ovarian-metastatic antigen-8 in human blood serum was worked out. OMA-8 level was studied in blood serum of 40 healthy women, 40 healthy men, 16 neonates, 33 pregnant women, 103 patients with genital tumours. It was found out that OMA-8 level in blood serum of healthy women changed between 2 to 15.4(More)
Blood serum levels of ferritin and trophoblastic globulin were measured by immunoassay in 389 and 114 cases, respectively, suffering malignant or benign tumors of the uterus and ovary as well as in controls. Hyperferritinemia identified at serum ferritin levels in excess of 200 micrograms/l was established in 94% of cases of ovarian cancer, 57%--benign(More)
D-amphetamine and cocaine were found to facilitate septal self-stimulation. In low doses morphine, imipramine, benactyzine, meprobamat, diazepam, chlordiazepoxide, phenobarbital, LSD-25 failed to influence this index, but in high doses they depressed the self-stimulation. It is supposed that d-amphetamine and cocaine exerted a direct stimulating action of(More)
Probenecid at a dose 100 and 200 mg/kg, i.v. has been found to decrease in a dose-dependent manner the level of radioactivity of cerebrospinal fluid (CSF) measured at 1, 15, 30 and 60 min. after the intravenous injection of 14C-tyrosine, 14C-tryptophan and 14C-DOPA. Ethanol at a dose 2 and 4 g/kg, i. p. has not changed the level of radioactivity of the CSF.(More)
