The growing interest in the composition and effects of microbiota raised the question how drug pharmacokinetics could be influenced by concomitant application of probiotics. The aim of this study was to find whether probiotic E. coli strain Nissle 1917 (EcN) influences the pharmacokinetics of concomitantly taken antiarrhythmic drug amiodarone (AMI). Live(More)
OBJECTIVES The aim of the study was to find whether probiotic Lactobacillus casei influences the expression or the activity of cytochromes P450 (CYP) and whether it has an influence on the level of CYP mRNA in male rats. DESIGN Live bacterial suspension of L. casei was administered orally (gavage) to healthy male Wistar rats daily for 7 days. Control(More)
OBJECTIVES To study the contribution of individual purified porcine CYP1A2, 2E1 and 2A19 enzymes to the biotransformation of skatole. METHODS Individual porcine and human enzymes (CYP1A2, 2E1 or 2A6/19) were used to study their potential involvement in skatole metabolism. Furthermore, the inhibition experiments using specific inhibitors of CYP1A2, 2E1 or(More)
OBJECTIVES The aim of the study was to find, whether probiotic Escherichia coli Nissle 1917 O6:K5:H1 (EcN) influence the amount and activity of cytochromes P450 (CYP) in rat liver. DESIGN Live bacterial suspension of EcN was applied to the female Wistar rats in single dose or for 14 days consecutively. The bacterial lipopolysaccharide (LPS) isolated by(More)
OBJECTIVES The aim of the study was to find whether probiotic Escherichia coli Nissle 1917 O6:K5:H1 (EcN) influences the expression of cytochromes P450 (CYP) in the rat intestine. DESIGN Live bacterial suspension of EcN was administered to healthy male Wistar rats daily for 7 days. Control group of rats was stressed by oral application of the saline(More)
OBJECTIVES The study of interspecies differences in glucuronidation processes in the man, monkey, pig, dog and rat using liver microsomal fraction. The study is focused on determination of the enzyme activity of UGT1A6 (having also a toxicological importance) in microsomes of different species. METHODS For determination of glucuronides formed, an HPLC(More)
The probiotic bacterium Escherichia coli strain Nissle 1917 has previously been shown to alter the pharmacokinetics of amiodarone. The aim of this study was to determine whether the probiotic bacterium Lactobacillus casei produces similar alterations in amiodarone disposition. A suspension of live probiotic bacteria L. casei strain DN-114 001 (1.5 × 109(More)
OBJECTIVES Flavanol dihydromyricetin (DHM) has been shown to counteract acute ethanol (EtOH) intoxication and reduce excessive EtOH consumption. Since this flavonoid is being considered for human use, the in vivo study of DHM interactions with the cytochrome P450 (CYP) multienzyme system in the respect of metabolic activation of a model food-born(More)
