Diabetic encephalopathy is one of the severe complications in patients with diabetes mellitus. Findings indicate that saffron extract has antioxidant properties but its underlying beneficial effects on diabetic encephalopathy were unclear. In the present study, the protective activities of saffron were evaluated in diabetic encephalopathy. Saffron at 40 and 80 mg/kg significantly increased body...

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...

Considering the global popularity and also the various biological and medicinal properties of saffron, this study was conducted to assess the influence of its aqueous extracts administration on blood pressure, pressure-rate product (PRP) and electrocardiogram (ECG) indices of rat. Animals were divided to control (CTL), SAF50, SAF100, and SAF200 groups that orally received tap water, aqueous ext...

In the present study, the possible reversal effects of saffron against established aluminum (Al)-toxicity in adult mice, were investigated. Control, Al-treated (50 mg AlCl(3)/kg/day diluted in the drinking water for 5 weeks) and Al+saffron (Al-treatment as previously plus 60 mg saffron extract/kg/day intraperitoneally for the last 6 days), groups of male Balb-c mice were used. We assessed learn...

Cognitive deficits have been observed in patients with multiple sclerosis (MS) because of hippocampal insults. Oxidative stress plays a key role in the pathophysiology of MS. The aim of this study was to evaluate the effects of Crocus sativus L., commonly known as saffron, on learning and memory loss and the induction of oxidative stress in the hippocampus of toxic models of MS. One week after ...

BACKGROUND Saffron is the dried stigma of Crocus sativus L. flower which commonly used as a natural remedy to enhance health and even fights disease in the Middle-East and Southeast Asian countries. METHODS This study was aimed to investigate protective effect of saffron extract and crocin in fatty liver tissue of high-fat diet induced obese rats. A total of 36 healthy male Sprague Dawley r...

Aluminium has been proposed as an environmental factor that may affect several enzymes and other biomolecules related to neurotoxicity and Alzheimer's disease (AD). The promising protective effect of aqueous saffron extract and honey syrup on neurotoxicity induced by aluminuim chloride (AlCl(3)) may be derived from their own antioxidant properties. Balb/c and C57BL/6 mice (35-40 g) were injecte...

BACKGROUND The cultivation of saffron is expanding through the southeast of Iran, and allergy to saffron pollen occurs in workers involved in processing this plant. We aimed to clone, sequence and express a major allergen involved in saffron pollen allergy, and to compare the recombinant with the natural allergen. METHODS The N-terminal amino acid sequence of Cro s 1, an allergen from saffron...
