Inhibitory effects of kale ingestion on metabolism by cytochrome P450 enzymes in rats.

Kale (Brassica oleracea L. var acephala DC) is a leafy green vegetable belonging to the cabbage family (Brassicaceae) that contains a large amount of health-promoting phytochemicals. There are any reports about the effects of kale ingestion on the chemoprevention function and mechanism, but the interactions between kale and drugs have not been researched.

Effects of kale ingestion on pharmacokinetics of acetaminophen in rats.

Kale is a cruciferous vegetable (Brassicaceae) that contains a large amount of health-promoting phytochemicals. The chronic ingestion of cabbage of the same family is known to accelerate conjugating acetaminophen (AA) and decrease the plasma AA level. Therefore, we examined to clarify the effects of kale on the pharmacokinetics of AA, its glucuronide (AA-G) and sulfate (AA-S).

Changes in catecholamines and dopaminergic metabolites in pigeon brain during development from the late embryonic stage toward hatch.

While brain development during embryogenesis has been extensively studied in precocial birds, there is no information available on altricial birds. Thus, the concentrations of the catecholamines norepinephrine (NE), epinephrine (E), and dopamine (DA), and the dopaminergic metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and 4-hydroxy-3-methoxyphenylacetic acid (HVA) were determined at several stages during the late embryonic period (E13, E14, E15, E16, E17 and E18) and the day-of-hatch (P0) in the pigeon telencephalon, cerebellum, optic lobe, and brainstem. The concentrations of all catecholamines were higher than those reported in chicken embryos.

Chicken ghrelin and growth hormone-releasing peptide-2 inhibit food intake of neonatal chicks.

Ghrelin is an endogenous ligand for the growth hormone secretagogue (GHS) receptor. Ghrelin stimulates feeding in rats, however, intracerebroventricular (i.c.
