The effect of continuous low-power He-Ne laser on the hatching rate and life span of Artemia urmiana
Artemia, as live food, is of vital importance in aquaculture. In this study, we have studied the helium-neon (He-Ne) laser beam with 10 mw on the hatching and life span of Artemia cysts. He-Ne laser irradiation was performed with a 10 mw power at 3, 4 and 5 h irradiation periods. Cysts were hatched by standard method. Hatching percentage after 4 h of irradiation was more than other treatments a...
متن کاملFrequency doubling of He–Ne laser radiation at 632.8 nm
Second harmonic generation (SHG) obtained using a potassium dihydrogen phosphate (KDP) nonlinear crystal from a CW He–Ne laser as a pump source, which emits at 632.8 nm, is reported. The SHG efficiency at the power of the He–Ne laser utilized (18 mW) and the fundamental beam waist available (0.1 mm), was evaluated theoretically; the same efficiency was measured experimentally obtaining a value ...
متن کاملChemiluminescence response of human neutrophils to He-Ne laser irradiation (in vivo and in vitro)
He-Ne laser irradiation (0.01 -6 3/cm3) of the blood and neutrophile suspension in vitrowas shown to modulate reactive oxygen species (RDS ) product ion in healthy donors. Intravascular laser irradiation of the blood ( 5 mW, 30 minutes, daily) of the patients with chronic gastric ulcer during first 5 days resulted in increasing stimul-k-duced ROS production in patients with the low initial chem...
متن کاملHe-Ne laser effects on blood microcirculation during wound healing: a method of in vivo study through laser Doppler flowmetry.
BACKGROUND AND OBJECTIVES Low-intensity laser therapy (LILT) is widely used for wound healing promotion and its mechanism of action may be due to an enhancement of blood supply. The aim of this study was to evaluate blood flow alterations in a wound healing model, using laser Doppler flowmetry (LDF) associated with a normalized perfusion parameter. STUDY DESIGN/MATERIALS AND METHODS An injury...
متن کاملCellular Responses by Low-power He-Ne laser Irradiation on Human Lung Cancer Cells
Helium-neon (He-Ne) laser has been used in many clinical fields, and caught our interest on cancer treatment. We conducted the study of He-Ne laser in lung cancer for the sake of the most common cause of cancer deaths worldwide, and up to 50% of the patients with advanced non-small-cell lung cancers with brain metastases. In this study, we used two human lung cancer cell lines A549, H1299, bron...
