The aim of this study is to examine the role of oxidative stress (OS) by measuring Malondialdehye (MDA) levels to test Lipid Peroxidation as a marker of oxidative stress in serum samples in toxic injuries resulting from exposure to anticholinesterase
insecticides (organophosphates and carbamates) in greenhouse workers in the coastal region of Syria. The study population comprised two groups (the majority of males): greenhouse workers who prepare and spray pesticides (100 workers, aged 18-61) and Control group (not never handle pesticides, 50 subjects, aged 19-58). Malondialdehye (MDA) levels were measured using enzyme-linked immunosorbent assay (ELISA). There was a significant difference in MDA levels in greenhouse workers group compared to control group (P˂0.05). Therefore, MDA levels could be considered as a biomarker for oxidative stress in greenhouse workers exposed to anticholinesterase insecticides and might be a useful diagnostic aid and monitoring exposure in those workers as well as cholinesterase enzyme.
In research we studied the effect of vitamin C on the level of total
cholesterol ،triglycerides ، (HDL) and (LDL) in the stressful
rabbits blood by hydrogen peroxide (H2O2) . We used 30 rabbits
were divided into three groups:First groupnot stresse
d (control
group) ، Second group (Group stressed by H2O2) left without
treatment until the end of the experimental period ، third group
(Group stressful by hydrogen peroxide) was given orally vitamin C
solution at a rate of 100 mg / kg of body weight per a day for five
weeks.
The goal of all prosthetic treatment is to obtain a satisfying
functional and esthetical oral status. Successful treatment outcome
following prosthetic treatment relies on healthy hard tissues but
also on healthy soft tissues. The aim of this study is to
comparatively assess the clinical and biochemical parameters in
gingival sulcus around the teeth received zerconium ceramic
crowns with supra and sub-gingival crown margin position.
