ComparativeIn Vitroevaluation of cumulative release of the urinary antiseptics Nalidixic acid, Pipemidic acid, Cinoxacin, and norfloxacin from white …
1994
AbstractThe in vitro diffusion of nalidixic acid (1), pipemidic acid (2), cinoxacin (3), and norfloxacin (4) was studied. The transfer rate constants (kd) from simulated gastro-intestinal juices to simulated plasma, throughout artificial wall lipid membranes, were defined. The kd values suggested that the four drugs are absorbed both in gastric and intestinal environments in similar amounts. To obtain lack of gastric unwanted effects white beeswax microspheres containing 1, 2, 3, and 4 were investigated as a vehicle for the drug intestinal release; they were prepared by the meltable dispersion process using wetting agents. Discrete, reproducible free flowing microspheres were obtained. The …
Effects of brofaremine (CGP 11 305A), a short-acting, reversible, and selective inhibitor of MAO-A on sleep, nocturnal penile tumescence and nocturna…
1987
The effects of brofaremine (CGP 11 305A), a short-acting, reversible and selective inhibitor of MAO-A, on sleep, nocturnal penile tumescence (NPT) and hormonal secretion during the night were studied during a long-term trial. Three healthy males underwent sleep-EEG and NPT recordings during consecutive nights (1) under placebo, (2) under stepwise increasing dosages of brofaremine and (3) under placebo after withdrawal. Hormone profiles were sampled during selected nights to analyze the plasma concentration of cortisol, HGH, prolactin, testosterone, LH and FSH. REM sleep was suppressed markedly under 150 mg brofaremine, while stages 1 and 2 increased. In comparison to the effect of irreversi…
Inherited semisterility for control of harmful insects. II. Degree of sterility and types of translocations in the mosquito Culex pipiens L.
1971
Fur die Anwendung von Semisterilitat infolge von Translokationen zur Bekampfung schadlicher Insekten ist der Grad der Semisterilitat und die Art der zugrundeliegenden Translokation von Bedeutung. Von den bisher untersuchten 124 Translokationen hatten 101 einen Sterilitatsgrad zwischen 10 und 50%, 23 uber 50 bis zu 85%. Mit dem mannlichen Geschlechtsfaktor M gekoppelte Translokationen sind zur Zeit die fur die Praxis am nutzlichsten. Sie treten nicht so haufig auf als erwartet, machen aber doch rund 1/4 aller getesteten Translokationen aus. Es werden Grunde angefuhrt, weshalb M-gekoppelte Translokationen nutzlicher sind.
DMPP and the adrenergic nerve terminal: mechanisms of noradrenaline release from vesicular and extravesicular compartments.
1977
DMPP (1,1-dimethyl-4-phenylpiperazine) in various concentrations between 1.6×10−6 M and 6.2×10−5 M was infused into isolated rabbit hearts to study the neuronal release and uptake of noradrenaline.
Low concentration of ziprasidone in human milk: a case report
2009
Although second-generation antipsychotics are established as the first-line treatment for schizophrenia, female patients are often excluded from this efficient treatment for safety reasons in pregnancy or whilst breastfeeding. For this reason, research on this subject mostly relies on case reports, although there is a great need to establish modern guidelines for treatment. Milk-to-plasma (M:P) ratios have been reported for clozapine (2.79–4.32; Winans, 2001), olanzapine (0.10–0.84; Gardiner et al. 2003), risperidone/9-OH risperidone (0.10–0.42/0.24–0.50; Gentile, 2004) and aripiprazole (0.18–0.20; Schlotterbeck et al. 2007). According to one case report, the infant ingests 0.09–0.43% of th…
Secondary metabolites from polar fractions of Piper umbellatum.
2012
Seven known secondary metabolites were isolated from the methanol extract of the branches of Piper umbellatum. The identification of these compounds was mainly achieved by 2D NMR spectroscopic techniques and FAB-MS. Among them, the known cepharadiones A and B can be considered as chemotaxonomic markers of the genus Piper.
Aripiprazole in human milk
2007
Second-generation antipsychotics are now the established first-line treatment for schizophrenia. However, there are limited data on the use of these compounds in pregnant and breastfeeding women with mental disorders. For ethical reasons, research on these subjects mostly relies on collection of single datasets of cases in order to establish treatment guidelines.
Prevention of the acute neurotoxic effects of phenytoin on rat peripheral nerve by H7, an inhibitor of protein kinase C.
1992
Abstract The neurotoxic effects of a single dose of phenytoin (150 mg/kg body weight) alone or 30 min after H7 (a protein kinase C inhibitor) injection (20 mg/kg body weight) were investigated in terms of peripheral neuromuscular function and Na + ,K + -ATPase activity of the sciatic nerve. This intraperitoneal injection of phenytoin induced complete blockade of muscle action potentials in the dorsal segmental muscles of the rat tail evoked by electric stimulation of the caudal nerve and a 40% decrease in the Na + ,K + -ATPase activity of the rat sciatic nerve when compared with control values, measured as the difference between total and ouabain-insensitive ATPase activity. Prior administr…
