The red-fleshed apples are from varieties of apples confer the competence and high ability in vitro to produce anthocyanins in their organs. Several factors affect the in vitro production of anthocyanins in plant tissue culture and to produce high, the optimizing of these factors are very necessary. Light is one of the most important factors that many studies have been done in this area but the...

Purpose: The aim of present investigation was to evaluate low frequency low-level infra red diode laser therapy for a third degree burn healing in rats skin.Materials and Methods: 36 rats were divided into groups one and two. On day zero three third degree burns were made on the dorsum of each rat by steam. In group one ,first burn were exposed to a 80 Hz –pulsed 890 nm infra red diode laser wi...

Purpose: The aim of present study is to evaluate the effect of a pulsed infrared low-level laser on wound healing in an experimental induced diabetic rat model.Materials and Methods: 18 adult rats were divided into 2 healthy and 1 diabetic groups. Diabete was induced by intraperitoneal administration of streptozotosin in diabetic group. Two full - thickness skin incisions were made on the dorsu...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
