In the present study, the effects of an ethanol and aqueous extract of saffron Crocus sativus and its constituents safranal and crocin on the stress-induced reduction in food intake, weight gain and anorexic time in mice were investigated. Male albino mice (20-25 g) were irregularly exposed to a trial of electroshock stress for 7 days. Then, the anorexic time as well as the animal's food intake and weight were recorded. In addition, blood samples were obtained on days 1 and 7 for corticosterone determination. Intraperitoneal (i.p.) administration of the aqueous but not the ethanol extract (10, 50 and 100 mg/kg) significantly reduced the anorexic time. The results were similar for crocin (1, 5 and 10 mg/kg; i.p.). In addition, a reduction in weight gain was observed in the controls as well as in the groups that received alcohol extract or safranal. However, this was not observed in animals treated with aqueous extract or crocin. The plasma corticosterone level did not increase in the aqueous extract and crocin treated animals. It can be concluded that the saffron aqueous extract and its constituent crocin reduce side effects of electroshock stress in mice.

Sulfur mustard is an alkylating agent that reacts with ocular, respiratory, cutaneous, and bone marrow tissues. Main late respiratory complications are chronic obstructive pulmonary disease, bronchiectasis, asthma, and bronchiolitis obliterans. The aim of the present study was to identify differentially expressed proteins in bronchoalveolar lavage (BAL) fluid of control healthy and sulfur mustard-exposed lung disease patients. The BAL protein profile of ten healthy and 30 exposed patients with mild, moderate, and severe conditions (ten males in each group) were separated with 2-D SDS-PAGE and differentially expressed protein spots were successfully identified with MALDI TOF TOF MS. Among the differentially expressed proteins we observed a significant increase in vitamin D binding protein isoforms, haptoglobin isoforms, and fibrinogen especially in exposed moderate and severe lung diseases patients (p<0.01). Moreover, compared with healthy controls, significant decreases was noted in calcyphosine, surfactant protein A, and transthyretin in these patients (p<0.01). Apolipoprotein A1 was detected in all patients' BAL fluid but none of the healthy controls. Furthermore, S100 calcium-binding protein A8 was only detected in BAL fluid of moderate and severe groups. These findings will be useful to improve current methods of monitoring and helps to identify new therapeutic targets for treatment of this complicated illness.

Detection of myocardial apoptosis increased with prolongation of reperfusion time, as opposed to infarct detection where reperfusion was essential to detect infarction, but the infarct size did not increase with time. Pretreatment with hyperoxia significantly decreased infarct size and apoptotic cell death. Pretreatment, immediately before coronary occlusion, was most cardioprotective.
