Filed:

Feb 20, 2001

Appl. No.:

09/785549

Inventors:

Wei Dong Tian - West Roxbury MA
Pierre Trepagnier - Medford MA

Assignee:

Argose, Inc. - Waltham MA

International Classification:

A61B 500

US Classification:

600317

Abstract:

An instrument for evaluating fluorescence of a heterogeneous tissue includes means for exciting a two-dimensional portion of the tissue surface with excitation radiation at a plurality of excitation wavelengths, means for collecting emission radiation from the two-dimensional portion of the tissue surface simultaneously with excitation of the portion, and means for forming a two-dimensional excitation-emission map of the excitation radiation and the simultaneously collected emission radiation and spatially averaging the excitation and emission radiation.

Abstract:

The present invention is directed to methods for treating acne. The methods include exposing the subject afflicted with acne to ultraviolet light having a wavelength between about 320 to about 350 nm, such that the acne is treated, e. g. , inhibited, diminished, eradicated or prevented. In a preferred embodiment, the wavelength is 335 nm and is emitted by either a nitrogen laser or a third harmonic of a NdYAG laser. Treatments can be administered over a several week period, where the subject is exposed to sequential doses of ultraviolet light to obtain beneficial effects, e. g. , a reduction or elimination of the acne, e. g. , an eradication or diminishment of the bacteria responsible for acne, e. g. ,.
