Role of catecholamines in the central mechanism of emetic response induced by peruvoside and ouabain in cats.

1 Peruvoside, (a glycoside obtained from the plant, Thevetia neriifolia Juss) and ouabain produce emesis in cats. Vomiting is not produced by these drugs in animals pretreated with catecholamine depleting drugs like reserpine, tetrabenazine or syrosingopine. Chloropromazine hydrochloride, mepyramine maleate, or BOL-148 administered intravenously or intracerebro-ventricularly do not afford protection.2 Phenoxybenzamine produces partial protection against peruvoside-induced emesis.3 Haloperidol (1 mg/kg i.v.) prevents vomiting induced by peruvoside or ouabain. Intracerebroventricularly administered haloperidol is ineffective.4 Cats pretreated with SKF-525-A, are not protected by haloperidol. Animals pretreated with phenobarbitone in a dose of 25 mg/kg for a week were protected by haloperidol, 250 mug/kg i.e. one quarter of the effective antiemetic dose in normal cats.5 It is postulated that catecholamines are involved in the mechanism of vomiting induced by cardiac gycosides. Further, a metabolite of haloperidol seems to be responsible for its effective antiemetic action.

One year follow-up of total abstinence in chronic alcoholic patients following emetic counterconditioning.

The present study is a crossvalidation in the Fair Oaks Raleigh Hills Hospital of a 1970 outcome study by Wiens et al. from the Portland Raleigh Hills Hospital. The 1975 Fair Oaks crossvalidation sample included all 275 patients treated during 1975. These results were further recrossvalidated using all 290 patients treated in the Fair Oaks hospital during 1976. Results were 12-mo abstinence levels of 63% for the 1970 Portland sample and 39% and 50%, respectively, for the two Fair Oaks cross-validation samples. If the more stringent total abstinence without a slip of a single drink was the outcome measure used, these 1975 and 1976 12-mo abstinence levels became 33% and 43%, respectively. Additional analyses revealed the important role in these outcome rates of such demographic variables as Medicare recipient status, marital status, employment status, and a combined status of married and employed.

Toxin gene profiling of enterotoxic and emetic Bacillus cereus.

Very different toxins are responsible for the two types of gastrointestinal diseases caused by Bacillus cereus: the diarrhoeal syndrome is linked to nonhemolytic enterotoxin NHE, hemolytic enterotoxin HBL, and cytotoxin K, whereas emesis is caused by the action of the depsipeptide toxin cereulide. The recently identified cereulide synthetase genes permitted development of a molecular assay that targets all toxins known to be involved in food poisoning in a single reaction, using only four different sets of primers. The enterotoxin genes of 49 strains, belonging to different phylogenetic branches of the B. cereus group, were partially sequenced to encompass the molecular diversity of these genes. The sequence alignments illustrated the high molecular polymorphism of B. cereus enterotoxin genes, which is necessary to consider when establishing PCR systems. Primers directed towards the enterotoxin complex genes were located in different CDSs of the corresponding operons to target two toxin genes with one single set of primers. The specificity of the assay was assessed using a panel of B. cereus strains with known toxin profiles and was successfully applied to characterize strains from food and clinical diagnostic labs as well as for the toxin gene profiling of B. cereus isolated from silo tank populations.

Co-identity of the refusal and emetic principle from Fusarium-infected corn.

The structure of vomitoxin isolated from Fusarium-contaminated corn was proved to be 3,7,15-trihydroxy-12,13-epoxytrichothec-9-en-8-one. This same toxin is responsible for the "refusal phenomenon" exhibited by swine fed contaminated corn. In addition, two new substances believed to be trichothecenes were isolated from naturally infected corn. Vomitoxin was also isolated from rice inoculated with F. graminearium NRRL 5883.
