    Notes: Abstract Laser light of low energy is discussed to have an accelerating effect on wound healing. The aim of the present study was to proof whether HeNe laser irradiations have a positive effect on regeneration of capillaries. For this purpose aluminium chambers were implanted in the dorsal skin flap of Syrian hamsters. After coagulation of blood vessels by means of an argon laser the tissue was irradiated daily with the low energy light of a HeNe laser. Regeneration of capillaries was studied by means of intravital microscopy. The results of the study revealed a positive effect of low dose HeNe laser irradiation on the regeneration of capillaries at day 5 after the coagulation. The measurable part of the capillaries was about 27% higher for the irradiated animals compared to controls.

    Description / Table of Contents: Summary We compared a cw carbon dioxide flash-scanning laser system to an Er:YAG laser in laser skin resurfacing of facial rhytides. In all patients, CO2 laser treatment showed a better cosmetic result whereas erythema and postinflammatory hyperpigmentation were less marked in Er:YAG laser therapy.
    Notes: Zusammenfassung Anhand einer klinischen Studie vergleichen wir einen cw-CO2-Laser mit Scannersystem mit einem Er:YAG-Laser hinsichtlich Wirksamkeit und Nebenwirkungsspektrum bei der Laser-Faltenbehandlung. Bei sämtlichen behandelten Patienten zeigte sich der CO2-Laser bezüglich des kosmetischen Endergebnisses dem Er:YAG-Laser deutlich überlegen. Erythem und postinflammatorische Hyperpigmentierung als in jedem Fall reversible Nebenwirkungen waren beim Er:YAG-Laser dagegen deutlich geringer ausgeprägt als beim CO2-Laser.
