The effects of NIK-247 on cholinesterase, scopolamine-induced amnesia and spontaneous movement were examined and compared with those of the well-known cholinesterase inhibitors tacrine and E-2020. NIK-247, tacrine and E-2020 all strongly inhibited acetylcholinesterase (AChE) in human red blood cells (IC50s = 1.0 x 10(-6), 2.9 x 10(-7) and 3.7 x 10(-8) M,(More)
Immunohistochemical expression of proliferating cell nuclear antigen (PCNA) was studied in the endometrium and in endometriotic lesions during the menstrual cycle and in post-menopausal patients. During the menstrual cycle, in the basal layer of the endometrium, an increase in the number of positive indices (PI) of PCNA was observed in epithelial cells from(More)
Orthodromic and antidromic conduction velocities were measured in the tail nerve of rats given lithium throughout life. Lithium at nontoxic levels failed to influence nerve conduction velocities. Lithium at toxic levels (2 X 2.5 mmol/kg/day for 7 days) produced overt signs of lithium intoxication and reduced both orthodromic and antidromic nerve conduction(More)
In order to investigate the blood compatibility of autogenous vein graft (AVG), changes in prostacyclin (PGI2) production following harvesting and arterial implantation were studied experimentally. Basal PGI2 production, which means the value obtained without stimulation by arachidonic acid (AA), decreased significantly 60 minutes after harvesting. At this(More)
Immunohistochemical studies were carried out on cutaneous glomus tumours from 10 patients. The glomus areas in these tumours reacted strongly with anti-smooth muscle (CGA-7), anti-muscle (HHF-35) and anti-vimentin antibodies. Their neural supply was analysed using several nervous tissue markers (anti-neurone specific enolase, anti-S 100, anti-Leu 7,(More)
