Pharmacological study of [2-chloro-11-(2-dimethylaminoethoxy) dibenzo[b,f]thiepine] (zotepine), a new neuroleptic drug.

2-Chloro-11-(2-dimethyl-aminoethoxy)dibenzo [b,f]thiepine (zotepine) is a new neuroleptic drug with a chemical structure different from known neuroleptics. The psychopharmacological effects of zotepine in mice, rats and dogs were studied and compared with those of commercially available neuroleptics. Haloperidol and perphenazine were the most active and thioridazine was the least active in hibiting apomorphine-induced gnawing and circling movement, methamphetamine-induced gnawing and circling movement, conditioned avoidance response, motor activity, dopamine-induced pancreatic secretion and apomorphine-induced vomiting. These drugs also had the same order of potency in inducing catalepsy and increasing dopamine turnover and prolactin release. Chlorpromazine, propericiazine and thiothixene were intermediate in potency. Zotepine equalled chlorpromazine in most activities, however, it was clearly less active than chlorpromazine in potentiation of barbiturate sleep and cardiovascular effect.

A treatment of detrusor-sphincter dyssynergia: pudendal nerve block by phenolglycerin under the guide of direct nerve stimulation.

While applying direct electrical stimulation to the pudendal nerve and recording of electromyographic reactions of bulbocavernosus muscle and/or transverse perineal muscle, pudendal nerve block by phenol was performed for the treatment of dysuria due to detrusor-sphincter dyssynergia, resulting in a favourable response. The technique and the cases treated with this nerve block are presented.

Fetal case of xeroderma pigmentosum--first report of an autopsy case.

Fetal autopsy case of xeroderma pigmentosum was reported. This male fetus of 24 gestational weeks was prenatally diagnosed as xeroderma pigmentosum by detecting the DNA-repair defect of the amniotic fluid cells. Autopsy revealed not only maldevelopment of the fetus (stillbirth) in general for the standard, but also showed slight developmental retardation of various organs including kidneys and lungs, which could be examined by microscopic analysis. It was suggested that abnormality of the somatic organs began to appear at the fetal stage in this case of xeroderma pigmentosum.

Dopamine receptor blocking activity of sulpiride in the central nervous system.

Effects of sulpiride on the central nervous system were studied in catalepsy induction (I) and antagonism to gnawing behaviour (II) induced by apomorphine and methamphetamine in normal rats, and in antagonism to rotational behaviour (III) induced by apomorphine and methamphetamine in rats with substantia nigra unilaterally lesioned chronically by microinjection of 6-hydroxydopamine. Sulpiride was administered orally and intraventricularly, and the effects of sulpiride were compared to those of haloperidol and chlorpromazine administered through the same routes. In oral administration, sulpiride was almost inactive in (I), and was several hundreds to a thousand times less potent than haloperidol in (II) and (III), while chlorpromazine was 20 to 150 times stronger than sulpiride. In intraventricular administration, sulpiride was almost equipotent to haloperidol in (I), and was equally effective to or 2 to 3 times more effective than halopridol in (III), although several times less in all respects. These findings suggest that sulpiride is essentially a potent inhibitory substance on dopamine receptors in the central nervous system and the rather weak central effects of peripherally given sulpiride are due to poor penetration through the blood brain barrier.
