    Notes: [Auszug] We identified the subplate and marginal zone cells unam-bigously by their birthdate. These cells undergo their final round of cell division and migrate away from the ventricular zone between embryonic day 24 (E24) and E30 (gestation is 65 days in the cat)1. In contrast, cells of the cortical layers ...

    Notes: Abstract Chlorpromazine forms charge-transfer complexes with xanthene dyes in bacteria. These complexes permit the differentiation of Gram-positive and Gram-negative bacteria in both light and polarization microscopy. The birefringence induced by the charge-transfer complex might explain the molecular basis of bacterial staining. The charge-transfer complexes formed between chorpromazine and xanthene dyes accumulate in the bacterial cell, mainly inside the bacterial cell wall. The complexes give the cells a color, which depends on the chemical composition of the staining structure, and in particular the polysaccharides of the cell wall in bacteria. Metachromatic granules were seen inside Gram-positive bacteria after chlorpromazine and rose bengal staining. Although the nature of these granules remains unclear, this type of binding may have a role in the inhibition of biochemical processes in the bacterial cells.

    Notes: Abstract A simple test for the evaluation of drugs interfering with bacterial motility was established withProteus vulgaris. With this model, promethazine, 7-hydroxy-chlorpromazine, imipramine, 7,8-dioxochlorpromazine and acridine orange were shown to exert significant motility and swarming inhibitory action onProteus vulgaris strains at subinhibitory concentrations. Quinidine enhanced the antimotility effect of promethazine. The antimotility effect of promethazine was synergized by proton pump inhibitors omeprazole and abscissic acid, but antagonized by extracellular potassium and sodium ions.
