Studies of alizapride (N[(allyl-1 pyrrolidinyl-2) methyl] méthoxy-2 azimido-4,5 benzamide hydrochlorate) in mice and rats demonstrated little toxicity, particularly after parenteral administration. Alizapride's main pharmacodynamic effects are on the central nervous system. It is very effective against emesis induced by apomorphine and dihydrogenated ergot alkaloids in dogs. In this respect it is three times more effective than metoclopramide. In contrast to neuroleptics, alizapride does not modify equilibrium reflexes in mice, nor does it reinforce hypnosis induced by barbiturates.

A review of the hypnotic, anticonvulsant and brain protective action of etomidate in animals shows that when given as a single injection in different animal species recovery from hypnosis is quick and that the safety margin is large. In dogs a bolus or infusion produces high amplitude theta activity on the electroencephalogram (EEG). During infusion burst suppression is seen. After high doses, behaviour and EEG changes returned to normal within 3 hours. The wide spectrum of anticonvulsant activity suggests that etomidate may be useful in the treatment of status epilepticus.

Pavlov's development of the conditional reflex theory coincided with the rise of American behaviorism. Substituting an objective physiology for a subjective psychology, Pavlov saw in the rise of American behaviorism a clear confirmation of his method and theory.

The pharmacokinetics and clinical effects of the short-acting hypnotic R 8110 and of the narcotic analgesic fentanyl were studied in the dog. The effects of separate intravenous (i.v.) injections of R 8110 (4 mg/kg) and fentanyl (0.015 mg/kg) and of concurrent i.v. injection of the two were studied. After administration of R 8110, induction of hypnosis occurred within 1 min, maximal depth of anaesthesia and satisfactory analgesia and muscle relaxation were obtained after 5 min. The effects had decreased within 15 min and full recovery occurred within 30 min.

The pharmacological actions of N-(2,6-dimethylphenyl)-8-pyrrolizidineacetamide hydrochloride hemihydrate (SUN 1165), a new antiarrhythmic agent, on the central nervous system were studied in various experimental animals as compared with those of disopyramide, mexiletine and lidocaine, and the following results were obtained. 1. Acute toxicity of SUN 1165 in mice was similar to that of mexiletine, and twice as potent as compared with that of disopyramide and lidocaine.

Aqueous extract of the root of P. vulgare (PV) produced CNS depressant effect. It decreased the spontaneous motor activity, prolonged the pentobarbitone induced hypnosis, reduced body temperature and increased the reaction time to pain stimuli. PV also caused prevention against supramaximal electroshock and pentylenetetrazol induced seizures. PV showed a positive inotropic and chronotropic effect on perfused frog heart and caused hypotension and tachycardia in anaesthetised dogs. The effects were blocked by propranolol.

The effects of 1-[2-[bis (4-fluorophenyl)methoxy]ethyl]-4-(3- phenylpropyl) piperazine dihydrochloride (I-893) on the central nervous system were behaviorally and electroencephalographically investigated. Intraperitoneally injected I-893 (5-10 mg/kg) dose-dependently increased spontaneous motor activity in mice, but repeated injections did not affect the increase in the locomotor activity. In reserpinized mice, spontaneous motor activity was not increased by oral I-893.

Hypnosis has never been adequately explained in terms of conceptual framework of most schools of psychotherapy. The psychoanalytic concept that it consists of submission and surrender of important ego functions to the therapist does not explain all observed facts. During my wartime studies and since, I have been impressed by the observation that the patient's ego is by no means powerless and defenseless, even during a deep state of trance, i.e., in states of trance sufficiently deep to eliminate awareness of painful body injuries (1965).

The general pharmacological profile of 7-fluoro-1-methyl-3-(methylsulfonyl)- 4(1H)-quinolone BTS 53 554, CAS 76568-68-8), the main metabolite of a new vasodilator, flosequinan (BTS 49 465), was investigated. 1. The central nervous system: BTS 53 554 at the dose of 30 mg/kg i.v. caused an increase in respiratory rate and a sedation in general behavior in rats. The drug also inhibited acetic acid-induced writhing and slightly decreased normal body temperature in mice. However, the drug at the doses up to 30 mg/kg i.v.

Pharmacological effects of a new vasodilator, flosequinan (7-fluoro-1-methyl-3-(methylsulfinyl)-4(1H)-quinolone, BTS 49 465, CAS 76568-02-0) on the central nervous system, somatic nervous system, autonomic nervous system and smooth muscle, digestive system and miscellaneous organs were investigated. 1. The central nervous system: Flosequinan inhibited acetic acid-induced writhing at doses of more than 30 mg/kg p.o. and decreased body temperature and tended to decrease spontaneous movement slightly in mice at a dose of 100 mg/kg p.o.
