Chronic wound infections are typically polymicrobial; however, most in vivo studies have focused on monospecies infections. This project was designed to develop an in vivo, polymicrobial, biofilm-related, infected wound model in order to study multispecies biofilm dynamics and in relation to wound chronicity. Multispecies biofilms consisting of both Gram… (More)
1. 5-Hydroxytryptamine (5-HT) stimulates active sodium transport and decreases the passive mucosal to serosal chloride permeability across frog skin. The relative importance of the different regions of the 5-HT molecule in the mediation of these responses has been studied using a range of structurally related compounds. 2. Substitution in the ethyl amine… (More)
5-Hydroxytryptamine creatinine sulphate loses its biological activity when maintained at room temperature. The loss of 5-HT activity (in stimulating sodium transport across frog skin) is greater than the loss of creatinine sulphate activity (inhibition of sodium transport).
Human nonadherent peripheral blood mononuclear cells (PBMC) isolated from nonimmunized donors were preincubated for 18 h in medium alone or medium containing the lymphokine interleukin 2 and subsequently cocultured with tumor cells derived from malignant tumor cell lines or from fresh human tumors. The cell suspensions were subsequently inoculated into… (More)
Prostaglandin E1 noncompetitively inhibits 5-hydroxytryptamine- and theophylline-stimulated cyclic AMP production in the salivary glands of Calliphora erythrocephala by an inhibitory effect on adenyl cyclase. Phosphodiesterase is not affected.
1. Continual stimulation of frog skin epithelium and the salivary glands of the insects Calliphora and Musca with 5-hydroxytryptamine (5-HT) leads to desensitisation, i.e. the tissue fails to respond to the application of further 5-HT. 2. Incubation of desensitised frog skin and Musca salivary glands with either N-acetyl neuraminic acid or inositol… (More)
