In this study the effect of different doses of nicotine (0.125; 0.250; 0.500 mg/kg) on motoric activity in mice was tested by a T-maze model both during dark and light phase of the diurnal cycle. Low doses of nicotine (0.125 mg/kg; 0.250 mg/kg) increased motoric activity during the day. During the dark phase no stimulation was seen. A higher dose of(More)
The lipophilic components of choline phosphoglycerides and ethanolamine phosphoglycerides obtained from the salt gland of herring gull and eider duck and from the rectal gland of spiny dogfish were investigated by means of thin-layer chromatography, gas chromatography, and gas chromatography-mass spectrometry. All phospholipids analyzed were shown to(More)
Prevention of cardiotoxicity without interfering with the therapeutic efficacy of adriamycin is a very crucial question. We have investigated the activity of β-adrenoceptor coupled to guanine nucleotide binding regulatory proteins (G-proteins) and Ca2+-ATPase activity in experimental adriamycin-induced cardiotoxicity and the influence of metoprolol(More)
