OBJECTIVE Several phytochemical agents have been known to exhibit a neuroprotective effect. Among them, curcumin, linalool, rutin, safranal, and thymoquinone were widely investigated and neuroprotective activity of each of them was shown by several studies. This work was planned to investigate whether different combinations of them could induce better neuroprotective effect against glucose/seru...

PURPOSE We examined the effect of safranal, a constituent of Crocus sativus, in acute experimental animal models of generalized absence seizures. METHODS the effect of acute systemic administration of safranal on latency to seizure onset as well as spike and wave discharches (SWD) duration following pharmacologically-induced absence seizures was investigated in wildtype mice. We further chara...

OBJECTIVES Due to unsatisfactory response or intolerable side effects of current drugs, treatment of essential tremor remains inadequate. Thus, we aimed to investigate the protective and therapeutic effects of aqueous and ethanolic extracts of Crocus sativus (saffron), and its active consistent, safranal, on the harmaline-induced tremor in mice. MATERIALS AND METHODS To induce tremor, harmali...

Saffron and its constituents have been shown to decrease ischemia-reperfusion (I/R) injury in kidney or brain tissues. In this study, the effects of saffron ethanolic extract and its constituents, crocin and safranal, were evaluated in skeletal muscle during I/R injury. Hind limb ischemia was induced using clamping the common femoral artery and vein. After 2 h ischemia, the clamp of the femoral...

To study the mechanism(s) of the relaxant effects of Crocus sativus (Iridaceae), the stimulatory effect of aqueous-ethanolic extracts of this plant and one of its constituent, safranal was examined on beta-adrenoceptors in tracheal chains of guinea pigs. The beta(2)-adrenergic stimulatory was tested by performing the cumulative concentration-response curves of isoprenaline-induced relaxation of...

In this study, we investigated the anti-allodynia effect of safranal, the main volatile constitute of saffron, in spinal nerve transection model of rats. Meanwhile, to elucidate the mechanism, we determined the dynamic expression changes of glial activation markers (GFAP and OX-42) and inflammatory cytokines (TNF-α and IL-1β) in ipsilateral dorsal horn of lumbar enlargement post surgery. Result...

BACKGROUND Crocin and safranal are the active substances of saffron and have many biological properties. In the present study, we compared the effects of crocin, safranal and diclofenac on local inflammation and its induced pain in rats. METHODS Local inflammation was induced by intraplantar (ipl) injection of carrageenan (100 μl, 2%). Paw thickness was measured before and after carrageenan i...

objective: crocin and safranal are the main components of saffron, and have many biological functions such as anti-inflammatory and antioxidant activities. in the present study, we investigated the effects of crocin, safranal, morphine, diclofenac and naloxone in combined and separately on formalin-induced orofacial pain in rats. materials and methods: subcutaneous injection of a diluted formal...

Objective(s): In the current study, sunscreen and moisturizing properties of solid lipid nanoparticle (SLN)-safranal formulations were evaluated. Materials and Methods:Series of SLN were prepared using glyceryl monostearate, Tween 80 and different amounts of safranal by high shear homogenization, and ultrasound and high-pressure homogenization (HPH) methods. SLN formulations were characterized ...

OBJECTIVE(S) This study was designed to evaluate the cardioprotective effect of Crocus sativus L. (saffron) aqueous extract and safranal, the major constituent of the essential oil of saffron, on lipid peroxidation, biochemical parameters and histopathological findings in isoproterenol (ISO)-induced myocardial infarction in Wistar rats. MATERIALS AND METHODS The saffron extract (20, 40, 80 an...
