The effect of chlorpromazine (CPZ) on the shape of human erythrocytes with different values of transmembrane potential (TMP) was investigated. The shape of red blood cells with negative values of the TMP remained unchanged after the formation of stomatocytes by chlorpromazine, while cells with positive TMP showed a characteristic time course of shape change during the incubation with CPZ. Exper...

Both clinical observation and experimental animal studies have shown that chlorpromazine can produce disturbance of normal cardiac rhythm. Atrioventricular and intraventricular conduction defects have been demonstrated, as have various types of tachyarrhythmias, but there have been no reports of complete heart block, associated with the previous presence of right bundle-branch block and left an...

A method is described for estimating plasma and urinary hemoglobin concentrations as low as 3 mg/L. The assay measures at 528 nm the rate of peroxidation of chlorpromazine by hemoglobin and is not affected by ascorbate and bilirubin concentrations up to 500 mumol/L. Results by this method (mean +/- SD: 54.4 +/- 41.6 mg/L; n = 19) correlated well with those by a scanning spectrophotometric metho...

In intact urethane-anesthetized rats, plasma growth hormone (GH) levels were low but increased significantly following intravenous injection of chlorpromazine. Plasma GH levels were significantly elevated in rats with hypothalamic cuts such as complete deafferentiation, anterior cut and antero-lateral cut, whereas plasma GH levels in rats with posterior cut or postero-lateral cut were not sig...

BACKGROUND This is the first report testing the antibiotic resistance-modifying activity of Mentha arvensis against MRSA (methicillin-resistant Staphylococcus aureus). MATERIALS AND METHODS In this study an ethanol extract of Mentha arvensis L. and chlorpromazine were tested for their antimicrobial activity alone or in combination with conventional antibiotics against MRSA strains. RESULTS ...

Chlorpromazine hydrochloride, a synthetic phenothiazine, has been widely employed in psychiatric illnesses, and an extensive literature exists on its side-effects; many reports describe ocular changes, including an oculo-dermal melanosis with deposition of pigment in the retina (Feldman and Frierson, I964; Zelickson and Zeller, I964; Cairns, Capoore, and Gregory, I965; Brit. med. J., I967), dep...

Ebola virus (EBOV) infects several cell types and while viral entry is known to be pH-dependent, the exact entry pathway(s) remains unknown. To gain insights into EBOV entry, the role of several inhibitors of clathrin-mediated endocytosis in blocking infection mediated by HIV pseudotyped with the EBOV envelope glycoprotein (EbGP) was examined. Wild type HIV and envelope-minus HIV pseudotyped wi...

Chlorpromazine, a phenothiazine antipsychotic, is an old generation major tranquilizer that has remained relevant in the management of psychosis despite the advent of the newer atypical brands. Priapism, an uncommon urological condition may result from the alphaadrenergic blocking action of antipsychotics. A 46 years old man developed priapism in the course of treatment with chlorpromazine. He ...

DURING the past decade the drug treatment of psychiatric illness has advanced with remarkable rapidity. The principal drugs concerned are those with predominant actions on higher mental and neurological functions and collectively referred to as psychotropic drugs. The main drugs used in practice can be classified into (i) Anti-psychotic drugs (Neuroleptics). (2) Anti-depression drugs. (3) Anti-...

Chlorpromazine (3 x 10(-4)M) prevents the stimulation of adenyl cyclase activity in thyroid membranes produced by thyrotropin and prostaglandin, ACTH stimulation of adenyl cyclase in adrenal tissue, and glucagon- and epinephrine-stimulation of adenyl cyclase activity in liver. Baseline activity is unaffected. Parathyroid hormone stimulation of kidney preparations was not inhibited under these c...
