The aim of the present study was to investigate the effects of crocin - a natural antioxidant derived from saffron - on cardiac reperfusion-induced arrhythmia and antioxidant systems such as catalase and superoxide dismutase (SOD) enzyme activities, glutathione (GSH) and malondialdehyde (MDA, as a marker of lipid peroxidation) levels. Rats in 4 experimental groups were administered crocin (20 m...

OBJECTIVES Acrylamide (ACR) has many applications in different industries. ACR damages the central and the peripheral nervous system in human and animals. Importance of ACR-induced neurotoxicity encouraged researchers to find both different mechanisms involved in ACR neurotoxicity and potent neuroprotective agents. Therefore, this study was designed to investigate the protective effect of croci...

BACKGROUND Metabolic syndrome is defined by insulin resistance and a clustering of other cardiovascular risk factors. Crocin is a carotenoid derived from the stigmas of the saffron flower and had previously been shown to affect lipid profile. However, the mechanism for this function is not well understood. The present trial aimed to investigate the possible effect of crocin on plasma levels of ...

This study was designed to investigate the therapeutic effects of saffron (Crocus sativus L.) and its main constituent crocin on neuropathic pain behavioral responses induced by chronic constriction injury (CCI) in rats. Adult male Wistar rats (200 to 250 g) were randomly assigned into 5 groups: Sham + saline, CCI + saline, CCI+ saffron (30 mg/kg), CCI + crocin (15 mg/kg) and CCI + crocin (30 m...

Gardenia jasminoides is used in traditional Chinese medicine and has drawn attention as a rich source of crocin, a compound with reported activity against various cancers, depression and cardiovascular disease. However, genetic information on the crocin biosynthetic pathway of G. jasminoides is scarce. In this study, we performed a transcriptome analysis of the leaves, green fruits, and red fru...

OBJECTIVE The present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of Crocus sativus L. (saffron) using mice in two different regimens of acute and sub-acute administration. MATERIAL AND METHODS In acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...

The purpose of this study was to investigate the therapeutic effects of crocin on ovariectomy-induced osteoporosis in rats. Female Sprague-Dawley rats were randomly assigned to a sham-operated group (sham) and five ovariectomy (OVX) subgroups, that is, OVX with vehicle (OVX), OVX with 17β-estradiol (E 2, 25 μg/kg/day), and OVX with graded crocin doses (5, 10, or 20 mg/kg/day). Daily oral admini...

Background. Liver ischemia-reperfusion (IR) injury is one of the chief etiologies of tissue damage during liver transplantation, hypovolemic shock, and so forth. This study aimed to evaluate hepatoprotective effect of crocin on IR injury and on microRNAs (miR-122 and miR-34a) expression. Materials and Methods. 32 rats were randomly divided into four groups: sham, IR, crocin pretreatment (Cr), a...

objective(s): crocin, as the main carotenoid of saffron, has shown anti-tumor activity both in vitro and in vivo. crocin might interact with cellular proteins and modulate their functions, but the exact target of this carotenoid and the other compounds of the saffron have not been discovered yet. microtubular proteins, as one of the most important proteins inside the cells, have several functio...
