background noise exposure is known as a risk factor for hearing loss and one of its effects is noise-induced stress. cortisol as a stress hormone is used in noise-induced stress assessments. objectives the aim of this study was to measure and compare saliva cortisol concentrations in the morning and evening in normal work day and rest day in both case and control groups and to assess the associ...

interleukin-4 (il-4) is produced by t-helper cells type 2 (th2) and induces ige synthesis. t-helper cells type 1 (th1) produce interferon-gamma (ifn-gamma) which suppresses th2 and reduces il-4 induced ige production. in this :;tudy , we demonstrated that the levels of specific ige in the serum of atopic children (n=20) were elevated while il-4 production was increased and ifn-gamma secretion w...

conclusions with regard to the potent antioxidant properties of silymarin, the neuroprotective effects of this natural compound suggested in the current study may in part be mediated through inhibition of oxidative stress. results exposure to acr reduced cell viability in pc12 cells. pre-treatment of cells with silymarin (100 µm) significantly reduced acr-induced toxicity. in addition, administ...
