Disclosed herein is a modulator of vascular permeability using pulsed laser and a method for modulating vascular permeability using the same. More specifically, because the pulsed laser effectively induces vascular permeabilization, effectively delivers intravascular materials into tissues and minimizes insult to the tissues by the induced vascular permeabilization, and locally targets a subcutaneous tissue for noninvasive modulation due to its nonlinearity, it may be usefully used for modulation of permeability.

Modulator of vascular permeability using pulsed laser and method for modulating vascular permeability using the same

The present invention relates, in general, to a system for analyzing tissue perfusion using the concentration of indocyanine green and a method of measuring the perfusion rate using the system and, more particularly, to a system for measuring tissue perfusion by injecting indocyanine green into a living body, detecting variation in the concentration of indocyanine green with the passage of time, and analyzing the detected variation, and a method of measuring the perfusion rate using the system. The present invention provides a method of measuring perfusion in a living body, which enables accurate measurement for respective regions in a wide range from a perfusion rate decreased to less than 10% of normal perfusion to a perfusion rate increased to greater than normal perfusion using the above-described mechanism of ICG in a living body, which cannot be conducted using the conventional technology.
