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...
Introduction: Laser beam due to finest of incision and reduction of postoperative complication, facilitates airway surgery, but at the same time it increases the danger or firing and the airway management and protection becomes difficult during anesthesia. In this study, two general anesthesia methods (Intermittent Apneic Technique And Continuous Controlled Ventilation With Enveloped Endotrache...
introduction: tooth pain and sensitization are the two main causes of discomfort after periodontal flap surgery. effects of low level laser therapy for reducing pain have already been established; these kinds of lasers have been used for tooth desensitization as well. this controlled blind study sought to compare tooth pain and sensitization after 660nm laser irradiation in a split mouth and al...
introduction: male urethral stricture is a complicated urologic disease that could be successfully treated using internal urethrotomy. laser internal urethrotomy has been used in many cases with favorable outcome in many studies. holmium: yag laser with its incisional properties on tissue is one of the laser types applied for internal urethrotomy. methods: we present a 19 year-old male with his...
Background: Laser treatment is a rapid, non-invasive procedure for long-term hair removal. Lasers operate based on the principle of selective photothermolysis and target melanin in the hair follicle. We intend to determine the level of hirsute patient satisfaction with the alexandrite laser hair removal procedure.Methods: In this cross-sectional study 82 hirsute patient...
background: laser-tissue interaction on low-level laser therapy (lllt) has widespread medical applications (e.g., improved wound healing). the tensile strength of radiated tissue by lllt is known to be increased mainly because of cross collagen bands developed after radiation. objective: in this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic t...
Background and purpose: Low level lasers have been used in dentistry to stimulate orthodontic tooth movement and to inhibit the pain during tooth movements. Contradictory findings exist on this issue, therefore, this study evaluated the effect of laser therapy on pain during orthodontic tooth movement. Material and methods: In this clinical trial, 17 patients with extracted upper first premola...
Background and Aim: Infertility in men is 10-20% of cases due to azoospermia. The aim of this study was to investigate the effect of swimming training, cell and laser on the expression of genes involved in autophagy (LC3 and Beclin-1) in azoospermia mice. Methods: 30 rats 6 to 8 weeks of age were randomly selected from Tehran Laboratory Animal Research and Propagation Center, and then injected ...
Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...
diabetic macular edema (dme) is an important cause of blindness in the working population and is currently challenging to treat. current interventions include focal laser or intravitreal injections. this article outlines a new treatment protocol based on the concept that peripheral ischemia is the introduction to angiogenesis, that will ultimately gather its momentum at the fovea. performing ex...
