To Study the Changes of the Seminiferous Epithelium After Ga.Ai.As Laser Radiation (830Nm)
Purpose: The purpose of this study was to investigate the immediate effects of low power laser radiation (Ga-Al-As; 830nm) on the seminiferous epithelium of Sprague-Dawley rats. Materials and Methods: Male Sprague-Dawley rats were randomly divided into three groups (two experimental groups and the sham). The left testes of the animals were shaved, washed and marked at inferior pole. Then, they...
متن کاملThe Morphological Changes of Adult Mouse Testes after 60Co γ-Radiation
Background: Cytotoxic therapy can lead to prolonged azoospermia or even sterility. In the present study, we investigated the morphological changes of mouse testes after gamma-Radiation. Methods: After anaesthetizing of NMRI mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. Four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+1...
متن کاملAcute ultrastructural changes of cornea after excimer laser ablation.
Corneal ultrastructural changes induced by an argon fluoride excimer laser using different parameters were investigated. Twenty-eight rabbit corneas were ablated at light doses per pulse and repetition rates ranging from 25-800 mJ/cm2 and 1-100 Hz, respectively, at four different total light doses (25-150 J/cm2). Transmission electron microscopy showed that corneal ablations done at subthreshol...
متن کاملUltrastructural Changes in Human Trabecular Meshwork Tissue after Laser Trabeculoplasty
Purpose. To compare morphologic changes in human trabecular meshwork (TM) after selective laser trabeculoplasty (SLT) and argon laser trabeculoplasty (ALT). Design. Laboratory evaluation of ex vivo human eye TM after laser trabeculoplasty. Methods. Corneoscleral rims from human cadaver eyes were sectioned and treated with varying powers of either SLT or ALT. Specimens were examined using light ...
