Comparison of hair reduction with three lasers and light sources: prospective, blinded and controlled study.

Objective: The main goal of this study was to compare the hair removal efficacy of three methods: intense pulsed light (IPL), a combination of IPL and radio frequency (RF) and diode laser (810 nm).

Methods: Forty participants were treated within three standardized squares on lateral sites on their legs. Each of these squares was treated twice with an interval of 4-6 weeks.

Effect of Mahonia aquifolium active compounds on interleukin-8 production in the human monocytic cell line THP-1.

The effect of the crude extract and of two alkaloid fractions prepared from Mahonia aquifolium on interleukin-8 (IL-8) production in the lipopolysaccharide (LPS)-stimulated human monocytic cell line THP-1 was studied. The production of IL-8 by cells stimulated with 20 ng/ml LPS after 48 h treatment with 20 microg/ml crude extract was inhibited by about 30 %. LPS-stimulated cells treated with 0.
