Influence of emulsified fat on chlorpromazine availability in rabbit blood.

1974

Kaninchen uberlebten die letale Dosis von 30 mg/kg Chlorpromazin (i.v.) nur zusammen mit einer Fettinfusion (0,5 ml/kg/min Lipofundin S 10®). Es konnte in vitro gezeigt werden, dass der Zusatz einer Fettemulsion (Lipofundin S 10®) zu Kaninchenblut (25 mg Fett/ml) den Anteil an freiem Chlorpromazin (Gesamtkonzentration 10−4M) von 2,05% auf 0,87% herabsetzt.

Intracellul�re Verteilung von i.v. injiziertem Pb210 in Kaninchenorganen

1958

1. Die intracellulare Verteilung von Pb210wurde an Leber, Milz, Niere und Lunge von Kaninchen 1–35 Tage nach i.v. Applikation untersucht.

Isolation of endothelin A receptor from bovine lungs.

1995

We isolated endothelin receptor A (ET A ) from bovine lungs in a single-step purification procedure using antibodies raised against synthetic peptides that correspond to extra- and intracellular domains of the rat bradykinin receptor. Two receptor species of 55 and 35 kDa were isolated and subjected to N-terminal microsequencing. The difference between the observed and expected molecular weight species suggests that bovine ET A receptor is glycosylated.

Effects of rewarding electrical stimulation of lateral hypothalamus on classical conditioning of the nictitating membrane response.

1997

1. Adult New Zealand albino rabbits were prepared with chronic hypothalamic stimulating electrodes and hippocampal recording electrodes. 2. Rabbits were restrained and classically conditioned by a tone CS and an airpuff US either followed or preceded by a hypothalamic stimulation (HS). Control rabbits were conditioned without the HS. 3. It was found that HS following the CS facilitated both behavioral and hippocampal responses, while HS preceding the CS inhibited them. 4. Enhanced hippocampal learning-related unit firing to the CS may represent an early indication of conditioning before the behavioral activity produces any observable change.

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.

Erythrocyte agglutinins in the blood of certain Ascidians

1975

Plasma from Ciona intestinalis, Phallusia mamillata and Ascidia malaca possess hemagglutinin for a variety of erythrocytes. Results obtained by physical and chemical treatments suggest that hemagglutinin for Phallusia mamillata and Ascidia malaca may be a protein or a protein-like substance.

Cardiovascular effects induced by rolipram, a selective cAMP phosphodiesterase inhibitor: Interaction with adrenergic and calcium affecting drugs

1990

Time course of excitatory and inhibitory states of bulbar respiratory modulated neurons.

1980

In respiratory modulated neurons of rabbits, vagally mediated inhibition is not bound to resting membrane potential oscillations. Latency of spinally evoked antidromical spike invasion, however, is shorter and threshold voltage is lower during the shift of membrane potential towards depolarization accompanying burst discharge.

Unterschiede zwischen Tyramin und Dimethylphenylpiperazin in der Ca++-Abhängigkeit und im zeitlichen Verlauf der Noradrenalin-Freisetzung am isoliert…

1967

On the perfused rabbit heart a constant infusion of tyramine released noradrenaline continuously and independently of the external Ca++ concentration. In contrast, noradrenaline release by DMPP was only transient and required the presence of Ca++.

Funktionelle Bedeutung der Freisetzung von Dihydroxyephedrin und Dihydroxypseudoephedrin als ?falschen? sympathischen �bertr�gerstoffen am Herzen

1967

The experiments were carried out in order to investigate the functional significance of substitution of noradrenaline by amines known to exert actions weaker than those of the natural transmitter. On the isolated rabbit heart the potency relative to noradrenaline of (±)-dihydroxyephedrine to increase the rate was 1/4 and the potency to augment the contractile amplitude was 1/6. The corresponding values for (±)-dihydroxypseudoephedrine were 1/67 and 1/140, respectively.
