BACTERIOCIDAL EFFECT OF CO2 LASER IRRADIATION BIOPHYSICAL STUDIES

Experimental Studies of Model Drug Delivery Using Superpulse CO2 Laser

Effect of CO2 laser irradiation on hormesis induction in cultured oral cells.

BACKGROUND Many drugs (including toxicants) and radiation therapy have been reported to exert bi-phasic hormetic effects on cultured cells, but only when both the concentration and treatment time were optimal. Most previous studies have been carried out with multiple laser modalities other than CO(2) laser, and there has been no comparison of the hormetic response between normal and tumor cells...

Anterior chamber measurements on CO2 laser corneal irradiation.

At threshold irradiation (•—0.1 w./cm.) of the rabbit cornea with a carbon dioxide (COi) laser, there was no detectable rise in intraocular pressure and only a slight (1 to 2° C.) rise in aqueous temperature. On suprathreshold COt corneal irradiation, the intraocular pressure rose to a plateau, during irradiation and then gradually fell. There was a concomitant rise in temperature in the anteri...

Treatment of Rhinophyma with CO2 Laser

Rhinophyma is a benign and disfiguring tumor of the nose, affecting white old men. It represents the end stage of acne rosacea. Hypertrophy of the sebaceous apparatus and fibrosis lead to an enlarged, erythematous nasal tip with comedones. Treatment modalities include Isotretinoin (Which is not effective on severe rhinophyma), freehand scalpel shave, cryosurgery, electrocautery, dermabras...
