D-galactose induced aging reproduced in 48 animals of main group, and 12 rats in control group. All animals in main group were randomized for 4 groups: I. aging + saline, II - IV. different manufacturers 2% artichoke extracts (with content of chlorogenic acid 2.5%) in a dose of intradermal injection 0.13 mg twice at weeks during 4 weeks. Influence of artichoke extracts restored skin relative weight and led to an increase of solubility in neutral salt and acid, and decreased pepsin solubility collagen fraction, restored the hexosamine/collagen (hydroxyproline) ratio and decreased the activity of nuclear transcription factor (NF-kB). Local prolonged treatment with artichoke extracts improved collagen metabolism and attenuated the progression of inflammation in D-galactose induced skin aging model.展开更多
