Effect of a helium-neon laser on cutaneous inflammation.
A Helium-Neon (He-Ne) laser with a wavelength of 632.8 nm is known to have photobiological effects and is widely used for reducing the pain of herpes zoster and accelerating wound healing, however the cellular mechanism and effect of the He-Ne laser are poorly understood. The present study was designed to examine the influence of He-Ne laser irradiation on irritant and allergic contact dermatit...
متن کاملEffect of helium-neon laser auriculotherapy on experimental pain threshold.
This study was conducted to examine the effects of helium-neon laser auriculotherapy on experimental pain threshold. Eighty healthy female and male subjects, aged 18 to 39 years, were assigned randomly to one of two treatment groups. Subjects in the Experimental Group (n = 41) received laser stimulation, and subjects in the Control Group (n = 39) received sham stimulation to appropriate acupunc...
متن کاملCreating a Cavity-Dumped Helium Neon Laser
We use an acousto-optic modulator to quickly extract circulating optical power from a homebuilt 1.4 m open-cavity helium neon oscillator. We can extract 100 ns pulses with a maximum peak power of approximately 2 mW at a repetition rate of 100 kHz. We can attain repetition rates of over 1 MHz with decreased peak power. This work was supported by the Laser Teaching Center at Stony Brook Universit...
متن کاملa study on the effect of helium-neon laser irradiation over colagen synthesis in fibroblast cells
introduction: this study was conducted to evaluate the fibroblast healing of tenotomized dutch rabbits treated with a low power laser radiation. materials and methods: male rabbits were divided in a control and exprerimental groups randomly. achills tendon of animals was cut about 1.5cm above its calcaneal insertion and sutured according to the modified kessler procedure. in the control groups,...
متن کاملEffect of Helium-Neon Laser Irradiation on Motility and Ultrastructure of Fresh and Frozen-Thawed Human Sperm
Purpose: Semen freezing is an important technique in human infertility treatment in many different patients but it damages sperms. Low-power lasers are physical agents that have biostimulatory effects. In this study, low-power helium-neon laser's (16J/cm2, one time irradiation) effect on motility and ultrastructure of fresh and frozen-thawed human sperm were studied. Materials and Methods: Thi...
