The frequency of micronuclei (MN) in cells of the nasal mucosa, oral mucosa and in lymphocytes was evaluated for 25 students in anatomy classes exposed to formaldehyde (FA) over an 8-week period. Each student served as his or her own control. The time-weighted average concentration (TWA) of formaldehyde in anatomical laboratories and in students'(More)
The present report evaluates the effects of formaldehyde (FA) exposure on peripheral lymphocytes by using both genetic and immunological parameters. Twenty-three non-smoking students in the study had inhalation exposure to 0.508 +/- 0.299 mg/m3 of FA for a period of 8 weeks (3h x 3 times each week) during anatomy classes. As for composition of lymphocyte(More)
PURPOSE To compare the efficacy and safety of laser in situ keratomileusis (LASIK) and photoastigmatic refractive keratectomy (PARK) to treat moderate and higher myopic astigmatism. METHODS A retrospective nonrandomized study of 78 eyes with myopic astigmatism (range, 2.00 to 6.00 D) was undertaken. Thirty-eight eyes were treated with LASDK and 40 eyes(More)
In order to explain the effects of exposure on the neurobehavioral development of , a two generations-one nest reproductive test was used. Wistar were exposed to fluoride and arsenic for two generations. The results demonstrated that: with the increasing concentrations of fluoride and arsenic, the positive rates of early physiological development and nerve(More)
BACKGROUND Nonunions of the tibia represent challenging orthopedic problems, which require the surgeon to analyze numerous factors and choose an appropriate treatment. This article presents a case report of tibia and fibula fracture patient who failed the internal fixation surgery and successfully recovered after one course of percutaneous autologous(More)
