Background: Opiates affect blood factors as well as pain and inflammation in a gender-dependent manner. The aim of the present study was to evaluate the effects of morphine on serum glucose, cholesterol, triglycerides, and urea in gonadectomized and inflammation conditions. Methods: Animals were divided as follows: control group, carrageenan and chronic morphine recipients, acute morphine recip...

conclusions serum ngal levels of arf and crf patients were significantly higher than healthy individuals. in addition, ngal values of patients with crf were significantly higher than those of arf. serum ngal values can be used to detect renal injury and differentiate arf and crf. results median ngal levels in patients was 304.50 (29), and 60 (0) in control, which was statistically significant b...

Background: Brucella is a well-known intracellular bacterium entailing acute and chronic illnesses in humans and domestic animals. The infection chronicity may be affected by the cell-mediated immunity and cytokine patterns. Objective: To evaluate the patterns of T-helper cytokines in patients suffering from chronic and acute brucellosis. Methods: In this cross-sectional study, 22 individuals w...

Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats.  Methods: Twenty-eight Wistar adult male rats were randomly all...

background meningitis is an inflammation of the membranes, which surround the brain and spinal cord. early treatment of bacterial meningitis can prevent serious complications. in the last two decades, three vaccines have been developed against the three main bacterial species implicated in meningitis of children in western countries and vaccine-preventable invasive bacterial meningitis has decr...
