Chlorpromazine, levopromazine and promethazine exerted a bacteriostatic effect on Gram-positive bacteria at 20-60 mug/ml, on Gram-negative bacteria at 130-180 mug/ml concentration. Of the three compounds, chlorpromazine had the most marked bactericidal effect on cultures of Bacillus anthracis growing in minimal medium. In addition, chlorpromazine had a(More)
A series of drugs which potentiate or antagonize transmission at cholinergic synapses have been tested on the slow depolarizing dorsal root potentials evoked by stimulation of adjacent dorsal and ventral roots. Some drugs acted specifically on the dorsal root potential evoked by ventral root stimulation. Dihydro-beta-erythroidine, atropine and acetylcholine(More)
BACKGROUND Anthocyanins, compounds that represent the major group of flavonoids in berries, are one of the most powerful natural antioxidants. The aim of this study was to evaluate biological activities and comparison of anthocyanin-rich extracts prepared from chokeberry (Aronia melanocarpa), elderberry (Sambucus nigra), bilberry (Vaccinium myrtillus) and(More)
Blood and extracts of gut of the American cockroach, Periplaneta americana, powerfully stimulate contractions of the isolated rat uterus. The contractions are characterized by long latency and a prolonged relaxation phase having superimposed rhythmic contractions. Evidence indicates that the stimulating factor is not acetylcholine, 5-hydroxytryptamine,(More)
Probiotic bacteria are frequently used for prevention of bacterial infections of the gastrointestinal tract, but there are only limited studies on their efficacy against viral gut infections in animals. The aim of this study was to investigate the effect of probiotic Lactobacillus reuteri L26 BiocenolTM on the innate and adaptive immune responses in(More)
