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...
Background and purpose: Laser bean produces thin incision along with hemostasis, sterility and decreased postoperative complications, hence facilitate air way surgery, but due to proximity of endotracheal tube to operation site, the risk of occupying and burning of endotrachel tube and surrunding tissues in each surgery is about 0.5% to 1.5%. This study is about the complications arised by...
Today laser has a lot of usage in medicine and dentistry. In the field of dentistry, laser is used in soft tissue surgery, sterilization of canals (in root canal therapy) and in restorative dentistry laser is used for cavity preparation, caries removal, sealing the grooves (in preventive dentistry), etching enamel and dentin, composite polymerization and removal of tooth sensitivity. The use of...
We report on the synergy of an integrated ultrasound (US) and photoacoustic (PA) probe system for intravascular imaging. The combined dual-modality probe is based on a 39 MHz ring-shaped US transducer which detects both US echoes and laser-generated PA signals. By combining optical fiber, US transducer, and micromirror, we can obtain intravascular cross-sectional B-scan images by internal illum...

were found to have evidence of a generalized hemostatic disorder. These patients could be divided into three groups. The first group consisted of three patients with increased fibrinogen catabolism without clinical or laboratory evidence of intravascular coagulation. The second group of five patients had laboratory evidence of intravascular coagulation without clinically evident bleeding or thr...
Laser speckle contrast imaging (LSCI) is a powerful and simple method for full field imaging of blood flow. However, the depth dependence and the degree of multiple scattering have not been thoroughly investigated. We employ three-dimensional Monte Carlo simulations of photon propagation combined with high resolution vascular anatomy to investigate these two issues. We found that 95% of the det...

intravenous laser blood irradiation was first introduced into therapy by the soviet scientists en.meschalkin and vs.sergiewski in 1981. originally this method was developed for the treatment of cardiovascular diseases. improvement of rheologic properties of the blood as well as improvement of microcirculation and reduction of the area of infarction has been proved. further, reduction of dysrhyt...
