Crocin, as a carotenoid compound of saffron, exerts a potent antioxidant property. Mesalazine is frequently used in the treatment of ulcerative colitis. This study investigated the effects of separated and combination treatments with crocin and mesalazine in a rat model of ulcerative colitis. Ulcerative colitis was induced by intra-colonic administration of acetic acid (4.00%, 1.00 mL) at 8 cm ...

Background: Obesity is pandemic worldwide and a strong risk factor for cardio-metabolic disorders. The few approved anti-obesity drugs have poor efficacy and safety profile. Thus, there is an urgent need for new anti-obesity agents. According to the traditional medicine and a clinical trial, saffron may have anorexigenic and anti-obesity effects which need further investigation. Objectives: Ev...

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...

background: saffron is the dried stigmata of the flowers of saffron (crocus sativus l., iridaceae). saffron and its major active constituents, crocin (crocetin glycoside), crocetin and safranal, have a variety of pharmacological effects including high antioxidant properties and crocetin has insulin sensitizing effect possibly due to its antioxidant activity. oral crocin is not absorbed and is h...

background: the cholinergic system plays an important role in learning and memory. administration of crocus sativus (saffron) or its constituent, crocin, facilitates the formation of memory. based on above findings, in the current study the effect of crocin in antagonizing retrograde amnesia induced by scopolamine, a cholinergic receptor antagonist, in rats was investigated by using shuttle box...

introduction: the glutamatergic system plays an important role in learning and memory. administration of crocus sativus (saffron) or its constituent, crocin, facilitates the formation of memory. this research investigated the effect of crocin on antagonizing retrograde amnesia induced by ketamine, a glutamatergic receptor antagonist, in rats by shuttle box. methods:  male wistar rats were teste...

background. the major side effect of cisplatin, used in some tumours, is nephrotoxicity. reactive oxygen species and oxidative damage are the most important factors in cisplatin-induced acute renal failure. the main purpose of this study is to investigate the protective effects of crocin against cisplatin-induced acute renal failure and oxidative stress in rat. methods. in this study, animals w...

Crocin, a component of saffron, showed hypotensive which is perhaps due to vascular smooth muscle relaxant effect. The relaxant effects of saffron on tracheal smooth muscle also could be due to its constituent, crocin. In the present study, the relaxant effects of crocin and its possible mechanisms on rat tracheal smooth muscle were investigated. The relaxant effects of three cumulative concent...

Background and Aim: Diabetes can lead to reduced fertility in men by production of free radicals. Crocin (the effective component of saffron) with its antioxidant property can be effective in elimination of free radicals. We evaluated the effects of crocin on the reproductive parameters of the STZ –induced diabetic male Wistar rats. Materials and Method: Rats were made diabetic with...
