The Effect of Electromagnetic Waves Exposure on Blood Parameters

Background: Now a days researchers have shown grean interest in electromagnetic waves which spread from devices such az microwaves,satellites,tv,cell phones etc,due to various reports of their devasting effects on animal growth and health.in this study the effects of these radiations on blood cells is investigated.Methods: In the present study the effect of radiation on blood parameters in the factory workers, including welders, computer operators, individuals working in the furnace and the control group were investigated. In order to determine changes in blood parameters, blood samples were taken from the workers and then were analyzed by standard procedures and compared with control group of changes in blood parameters. Spss soft ware for data analysis and one-way ANOVA and Duncan test was used.Results: Results have shown that individuals affected by these waves show significant increase in the amount of RBC, MCV and platelet (P <0.05). While the amount of hemoglobin, the percentage of lymphocytes and WBC was reduced.Conclusion: These effects could be due to the stimulatory effects of radiation on cell division in bone marrow cells is But the effects of radiation on living systems requires further research

Customized stromal lenticule implantation for keratoconus

PURPOSE: To investigate the potential benefit of keratoconus surgery using customized corneal stromal donor lenticules obtained from myopic small incision lenticule extraction (SMILE) surgery by femtosecond laser. METHODS: In this prospective, consecutive, non-comparative series of cases, 22 lenticules were obtained from 22 myopic patients who had SMILE with a lenticule central thickness of greater than 110 µm. The lenticules were implanted in 22 eyes with advanced keratoconus. The lenticules were customized for the purpose of the implantation with either a simple necklace or necklace-with-ring shape (compound form) depending on the corneal thickness and corneal topography configuration of the implanted keratoconic eyes. The lenticules were implanted into a 9.5-mm corneal lamellar pocket created by the femtosecond laser. Changes in densitometry, thickness, confocal microscopy, corrected distance visual acuity (CDVA), and endothelial cell density were investigated. RESULTS: Intrastromal lenticule implantation was successfully performed in all cases without any complication. Corneal thickness showed a mean enhancement of 100.4 µm at the thinnest point. On biomicroscopy, all corneas were clear at 1 year postoperatively and there was a significant improvement in corneal densitometry during the entire follow-up period. Confocal biomicroscopy showed collagen reactivation without any inflammatory features caused by the implanted fresh lenticules. CDVA improved from 0.70 to 0.49 logMAR (P = .001) and keratometry decreased from 54.68 ± 2.77 to 51.95 ± 2.21 diopters (P = .006). CONCLUSIONS: Customized SMILE lenticule implantation by femtosecond laser proved to be feasible, resulting in an improvement in vision, topography, and refraction in the implanted eyes.
