[PMID: 38800027 PMCID: PMC11127087 DOI: 10.22038/ijbms.2024.75201.16301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 01/06/2024] [Indexed: 05/29/2024]
Abstract
Objectives Right ventricular hypertrophy (RVH) often results in failure of the right ventricle or even the left ventricle. Rosmarinic acid (RA), a natural polyphenol, is commonly found in Boraginaceae species and some species of ferns and hornworts. This study looked at how RA affects oxidative stress and left ventricular hemodynamic functions as well as RVH in monocrotaline (MCT) induced RVH model rats. Materials and Methods To cause RVH, MCT (60 mg/kg) was intraperitoneally (IP) injected. Rats were given saline or RA (10, 15, and 30 mg/kg, gavage, over 21 days). In anesthetized rats, the lead II electrocardiogram was recorded. The hemodynamic functions of the isolated heart were measured using the Langendorff apparatus (at constant pressure). Investigations were made into the right ventricular hypertrophy index (RVHI), the activities of superoxide dismutase, catalase, glutathione, and Wnt and β-catenin gene expressions in the left ventricle. H&E staining was used. Results A significant decline in electrocardiogram parameters and anti-oxidant enzyme activities, an increase in QTc (Q-T corrected) intervals, MDA (Malondialdehyde), RVHI, and Wnt/β-catenin gene expression, and also significant changes in the hemodynamic parameters were demonstrated in the MCT group. RA improved the above-mentioned factors. Conclusion According to the findings, RA may act as a cardioprotective agent against cardiovascular complications brought on by RVH due to its capacity to boost the activity of cardiac anti-oxidant enzymes and decrease the expression of genes involved in vascular calcification.

Analysis of Anti-Arrhythmic Impacts of Crocin through Estimation of Expression of Cx43 in Myocardial Infarction Using a Rat Animal Model. ACS OMEGA 2022; 7:37164-37169. [PMID: 36312395 PMCID: PMC9608388 DOI: 10.1021/acsomega.2c03158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Accepted: 09/01/2022] [Indexed: 06/16/2023]
Abstract
Arrhythmia is an important cause of death after myocardial infarction (MI). Different substances have been evaluated for their anti-arrhythmic effect in MI. This study was performed to evaluate the anti-arrhythmic impacts of crocin in an MI animal model (rat) by estimation of the expression of connexin 43 (Cx43). Fifty male Sprague-Dawley rats were grouped into 5 groups, each composed of 10 rats. The first group was regarded as the normal control group and the second one was considered as the MI group, which was caused by ligation of the left anterior descending artery. The other three groups received crocin 50 or 10 mg/kg/day or metoprolol 100 mg/kg/day for 1 week, following ligation of the left anterior descending artery. Evaluated outcomes were cardiac Cx43 expression, arrhythmia incidence, histological findings, and myocyte resting potential. Crocin-treated MI groups showed a significantly lower arrhythmia score than the non-treated MI group, 10 mg/kg/day (1.85 ± 0.55, p < 0.01) and 50 mg/kg/day (1.70 ± 0.33, p < 0.01). Groups that received crocin 10 mg/kg/day (66.30 ± 2.59, p < 0.01), crocin 50 mg/kg/day (68.10 ± 2.43, p < 0.01), and metoprolol 100 mg/kg/day (-63.54 ± 0.63 mV, p < 0.01) significantly prevented depolarization in comparison with the non-treated MI group. Expression of Cx43 mRNA in crocin 10 mg/kg/day (1.54 ± 0.24, p < 0.01), crocin 50 mg/kg/day (1.73 ± 0.09, p < 0.01), and metoprolol 100 mg/kg/day (1.75 ± 0.14, p < 0.01) treatment groups was significantly higher in comparison with the non-treated MI group. Crocin showed a preventive effect on the arrhythmogenic impact of MI in an experimental model of ischemic injury through an increase in expression of Cx43.

Protective effect of crocin on hemodynamic parameters, electrocardiogram parameters, and oxidative stress in isolated hearts of rats exposed to PM 10. IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:460-467. [PMID: 35656072 PMCID: PMC9150812 DOI: 10.22038/ijbms.2022.61163.13533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 04/13/2022] [Indexed: 11/13/2022]
Abstract
Objectives Exposures to particulate matter (PM) have been related to increased risk for cardiovascular health effects and can promote cardiac ischemia and oxidative stress. Crocin has strong antioxidant properties and stress-reducing effects. Therefore, this study considered the effect of crocin on cardiovascular parameters in rats exposed to PM10. Materials and Methods Forty Wistar rats (male, 250-300 g) were grouped as control, receiving normal saline and crocin, receiving PM10, receiving PM10+Crocin. Instillation of PM10 into the trachea was done. Forty-eight hours after exposure to the normal saline or PM, the heart was separated. Hemodynamic and electrophysiological factors were measured. The levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase activity (CAT), malondialdehyde (MDA), xanthine oxidase, were evaluated by kits. Results The voltage of the QRS complex was significantly reduced and PR and QTc intervals increased in PM10 groups. Hemodynamic parameters before ischemia and in the ischemic-reperfusion stage, in the PM10 group, showed a significant decrease. In the ischemic hearts of the PM10 group, a significant decline in the activity of CAT, SOD, and GPx, and a significant increase in MDA and XOX enzymes activity were observed, and crocin improved all of these factors. Conclusion Cardiac ischemia causes abnormal hemodynamic factors of the heart, which are exacerbated by PM10 and further reduce the heart's contractile strength. Increased oxidative stress due to PM10 is probably one of the important reasons for these changes. This study suggests that the use of antioxidants such as crocin improves the cardiovascular adverse effects of myocardial ischemia and PM10 exposure.

Abstract
Oxidative stress, caused by extreme accumulation of un-scavenged reactive oxygen species, plays an integral role in the Ischemia-Reperfusion (I/R) injury to the testicles following testicular torsion. The current research aimed to examine the protective effects of crocin as a natural antioxidant on testicular I/R injury in rats. Animals were divided randomly into five groups (seven each): (1) sham group, (2) torsion/detorsion (T/D) group, (3) intact group with 100 mg/kg crocin, (4) and (5) T/D groups followed by treatment with two different doses of crocin (50 and 100 mg/kg (IP)). I/R injury was induced by 720° clockwise torsion of the left testicles for 2 h. After 24 h of reperfusion, blood samples and epididymal sperms were collected to measure biochemical (GPx, SOD, and MDA), hormonal (testosterone), and sperm parameters (total sperm recovery, motility, viability, and morphology). Moreover, affected testicles were subjected to histopathology examination. I/R injury caused a significant reduction in sperm characteristics (except for morphology) (P < 0.05), which could not be significantly improved by crocin administration at either dose (P > 0.05). Johnsen's testicular score, mean seminiferous tubular diameter, and germinal epithelial cell thickness were significantly decreased in the T/D group compared to the intact and sham groups. However, crocin could significantly improve the histopathological parameters in both treatment groups compared to the T/D group (P < 0.05). T/D reduced SOD and GPx activity and testosterone level significantly (except for GPx) compared to the sham group (P < 0.05). However, crocin administration could significantly reverse them. Also, crocin reduced the amount of MDA significantly in the high-dose treatment group in comparison to T/D group (P < 0.05). The results of the current study revealed that crocin could be a promising agent to protect against I/R injury following surgical correction of the testicular torsion.

Abstract
Background and purpose Hyperglycemia induced oxidative stress and inflammation lead to development of diabetic cardiomyopathy. Diabetic patients are more at risk for myocardial infarction than non-diabetics. The current study has investigated the involvement of PPARγ activation in effects of crocin as a natural carotenoid against cardiac infarction in diabetic rats. Materials and methods Diabetes was induced in male Wistar rats by streptozotocin injection (55 mg/kg, i.p) 15 min after the administration of nicotinamide (110 mg/kg). Then saline, crocin (40 mg/kg, orally) and GW9662 (1 mg/kg, as PPARγ antagonist) were injected for 4 weeks. Isoprenaline was administrated on the 27th and 28th days to induce infarction. Cardiac injury markers, antioxidant enzymes content, blood glucose level, lipid profile, pro and anti-inflammatory cytokines, and PPARγ gene expression were measured. Results GSH, CAT content, CK-MB isoenzyme, LDH level, IL-10 and PPARγ gene expression in myocardial tissue were decreased in diabetic rats receiving isoprenaline and inflammatory cytokines TNFα and IL-6 and also plasma lipids were increased. Crocin administration significantly ameliorated inflammatory cytokines levels, CK-MB, and LDH contents and also it could enhance antioxidant capacity and PPARγ expression. However, GW9662 administration reversed the effects of crocin. Conclusion Overexpression of PPARγ in crocin treated rats and inhibition of crocin effects by GW9662 reflected the potential involvement of PPARγ pathway in the protective effects of crocin.

Abstract
OBJECTIVES The effects of Crocin as a cardioprotective material against Aluminum phosphide poisoning by reducing the oxidative stress is investigated. METHODS The level of biomarkers of oxidative stress (Catalase, Superoxide dismutase, Malondialdehyde and Protein carbonyl) were measured in the cell culture model on Human Cardiac Myocyte cells to detect the protective effect of crocin. Initially, to define the pure impact of aluminum phosphide poison and crocin on the heart cells, their effects on the biomarkers quantity in cell line were measured, separately, using the standard related kits. Later the effect of crocin with different concentration as a treatment on the oxidative stress biomarkers of the poisoned heart cells were monitored. Note that in pre-treatment case, the crocin was initially added to the cells before poisoning them. Data were analyzed using the analysis of variance method. KEY FINDINGS Results showed that crocin treatment reduced the aluminum phosphide (AlP) poisoning effect significantly. The treatment resulted in substantial deviation in the biomarkers of oxidative stress at the pre- and post-treatment phases for all groups. The oxidative markers values of the poisoned cells were recovered by crocin treatment. CONCLUSIONS Crocin is proposed as a potentially powerful antioxidant to treat the cardiotoxicity caused by aluminum phosphide poisoning.

Abstract
Saffron is commonly used in traditional medicines and precious perfumes. It contains pharmacologically active compounds with notably potent antioxidant activity. Saffron has a variety of active components, including crocin, crocetin, and safranal. Oxidative stress plays an important role in many cardiovascular diseases, and its uncontrolled chain reaction is related to myocardial injury. Numerous studies have confirmed that saffron exact exhibits protective effects on the myocardium and might be beneficial in the treatment of cardiovascular disease. In view of the role of oxidative stress in cardiovascular disease, people have shown considerable interest in the potential role of saffron extract as a treatment for a range of cardiovascular diseases. This review analyzed the use of saffron in the treatment of cardiovascular diseases through antioxidant stress from four aspects: antiatherosclerosis, antimyocardial ischemia, anti-ischemia reperfusion injury, and improvement in drug-induced cardiotoxicity, particularly anthracycline-induced. Although data is limited in humans with only two clinically relevant studies, the results of preclinical studies regarding the antioxidant stress effects of saffron are promising and warrant further research in clinical trials. This review summarized the protective effect of saffron in cardiovascular diseases and drug-induced cardiotoxicity. It will facilitate pharmacological research and development and promote utilization of saffron.

Abstract
Objective(s): One of the most important problems of taking nitroglycerin is the nitrate tolerance phenomenon and endothelial dysfunction. Oxidative stress is a high-emphasized one of tolerance mechanisms. The possible effect of crocin, one of the anti-oxidant ingredients of saffron, on the nitrate tolerance model was investigated. Materials and Methods: In the present study, lipid peroxidation and the level of activated and deactivated forms of eNOS were measured. Animals were administered subcutaneously with 25 mg/kg of nitroglycerin, twice a day for 3 days to induce nitrate tolerance model. For evaluation of crocin effects, 20, 40 and 80 mg/kg/day of this compound were injected intraperitoneally in concomitant with nitroglycerin. In the isolated aorta test, after preparation of aorta rings, different concentrations of acetylcholine, sodium nitroprusside and nitroglycerin were added to the organ bath after inducing contraction by phenylephrine and the responsiveness of tissues was recorded. Results: Findings showed that nitroglycerin administration caused a remarkable overproduction of malondialdehyde (MDA) in the cells and crocin treatment significantly decreased the MDA level. In the nitrate tolerance group, the level of activated eNOS decreased and the level of deactivated eNOS increased. Crocin partly alleviated these changes: however, its effects were not remarkable. Nitroglycerin injection for 3 days developed tolerance to nitroglycerin and cross-tolerance to acetylcholine (endothelial dysfunction) and sodium nitroprusside. Crocin failed to influence significantly on the nitrate tolerance. Conclusion: Crocin effectiveness is possibly time-dependent; therefore, increasing the duration of treatment with crocin may lead to a significant prevention of nitrate tolerance and endothelial dysfunction.

Abstract
Background Paraquat (PQ), as a pyridine compound, is widely used worldwide to control annual weeds. The oxidative stress caused by PQ can cause deleterious changes in the testicular tissue. Objective An investigation on the protective effects of Crocin (CCN) against PQ-induced oxidative damages and apoptotic indices in testicular tissue. Materials and Methods Twenty-eight adult male albino mice (20-25 gr) were divided into four groups (n = 7/each). The control group received 0.1 ml/day of normal saline by intraperitoneal injection (IP); sham-control group received PQ 5 mg/kg/day, IP, and the experimental groups received PQ (CCN+PQ) and CCN-sole (200 mg/kg/day, IP), respectively, for 35 continuous days. At the end of the treatment period, the testes were dissected out and used for biochemical, molecular, and histological analyses. The expressions of tumor suppressor p53, B-cell lymphoma 2 (bcl-2), and caspase-3 were considered as hallmark factors of mitochondria-dependent apoptosis. Moreover, the testicular superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluated as key biomarkers for oxidative stress. Results The PQ significantly (p < 0.02, p < 0.01) diminished the spermatogenesis indices and SOD, increased MDA levels, and enhanced the apoptosis-related gene expression. However, the co-administration of CCN and PQ significantly (p < 0.01, p < 0.01, p < 0.02) ameliorated the spermatogenesis ratio, upregulated the SOD level as well as bcl-2 expression, and reduced the MDA content and apoptosis vs the PQ-sole group. Conclusion This study showed that the antioxidant properties of CCN enable to ameliorate the PQ-induced destructive effects by upregulating the testicular structure, antioxidant and apoptotic status.

[PMID: 31670059 DOI: 10.1016/j.pharep.2019.07.007] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 06/23/2019] [Accepted: 07/19/2019] [Indexed: 11/19/2022]
Abstract
BACKGROUND Sepsis causes organ dysfunctions via elevation of oxidative stress and inflammation. Lipopolysaccharide (LPS) is the major surface molecule of most gram-negative bacteria and routinely used as a sepsis model in investigation studies. Crocin is an active compound of saffron which has different pharmacological properties such as anti-oxidant and anti-inflammatory. In this research, the protective effect of crocin was evaluated against LPS-induced toxicity in the embryonic cardiomyocyte cell line (H9c2). METHODS The cells were pre-treated with different concentration of crocin (10, 20 and 40 μM) for 24 h, and then LPS was added (10 μg/ml) for another 24 h. Afterward, the percentage of cell viability and the levels of inflammatory cytokines (TNF-α, PGE2, IL-1β, and IL-6), gene expression levels (TNF-α, COX-2, IL-1β, IL-6, and iNOS), and the level of nitric oxide (NO) and thiol were measured. RESULTS Our results showed that LPS reduced cell viability, increased the levels of cytokines, gene-expression, nitric oxide, and thiol. Crocin attenuated the LPS-induced toxicity in H9c2 cells via reducing the levels of inflammatory factors (TNF-α, PGE2, IL-1β, and IL-6, p < 0.001), gene expression (TNF-α, COX-2, IL-1β, IL-6, and iNOS, p < 0.001), and NO (p < 0.001), whereas increased the level of thiol content (p < 0.001). CONCLUSION The observed results revealed that crocin has preventive effects on the LPS induced sepsis and its cardiac toxicity in-vitro model. Probably, these findings are related to anti-inflammatory and anti-oxidant properties of crocin. However, performing further animal studies are necessary to support the therapeutic effects of crocin in septic shock cardiac dysfunction.

Abstract
OBJECTIVE Myocardial infarction (MI) is a leading cause of mortality and morbidity worldwide and new treatment strategies are highly sought-after. Paradoxically, reperfusion of the ischemic myocardium, as achieved with early percutaneous intervention, results in substantial damage to the heart (ischemia/reperfusion injury) caused by cell death due to aggravated inflammatory and oxidative stress responses. Chronic therapy with vitamin E is not effective in reducing the cardiovascular event rate, presumably through failing to reduce atherosclerotic plaque instability. Notably, acute treatment with vitamin E in patients suffering a MI has not been systematically investigated. METHODS AND RESULTS We applied alpha-tocopherol (α-TOH), the strongest anti-oxidant form of vitamin E, in murine cardiac ischemia/reperfusion injury induced by ligation of the left anterior descending coronary artery for 60 min. α-TOH significantly reduced infarct size, restored cardiac function as measured by ejection fraction, fractional shortening, cardiac output, and stroke volume, and prevented pathological changes as assessed by state-of-the-art strain and strain-rate analysis. Cardioprotective mechanisms identified, include a decreased infiltration of neutrophils into cardiac tissue and a systemic anti-inflammatory shift from Ly6Chigh to Ly6Clow monocytes. Furthermore, we found a reduction in myeloperoxidase expression and activity, as well as a decrease in reactive oxygen species and the lipid peroxidation markers phosphatidylcholine (PC) (16:0)-9-hydroxyoctadecadienoic acid (HODE) and PC(16:0)-13-HODE) within the infarcted tissue. CONCLUSION Overall, α-TOH inhibits ischemia/reperfusion injury-induced oxidative and inflammatory responses, and ultimately preserves cardiac function. Therefore, our study provides a strong incentive to test vitamin E as an acute therapy in patients suffering a MI.

The effects of prenatal androgen exposure on cardiac function and tolerance to ischemia/reperfusion injury in male and female rats during adulthood. Life Sci 2019; 229:251-260. [PMID: 31112711 DOI: 10.1016/j.lfs.2019.05.044] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 05/09/2019] [Accepted: 05/16/2019] [Indexed: 10/26/2022]
Abstract
AIMS Cardiovascular diseases may originate from suboptimal intrauterine environments. We aimed to examine the effects of prenatal androgen exposure (PAE) on heart basal hemodynamic parameters and tolerance to ischemia/reperfusion (I/R) injury, in PAE adult females and males. MAIN METHODS Pregnant Wistar rats in the experimental group (n = 8) received 5 mg of testosterone (s.c. injection) on the 20th day of pregnancy, while controls received solvent. The hearts of adult female and male offspring were isolated and perfused in a Langendorff apparatus, values of left ventricular systolic pressure(LVSP), left ventricular developed pressure(LVDP), rate pressure product(RPP) and peak rates of positive and negative changes in left ventricular pressure(±dp/dt) were recorded using a power lab system. KEY FINDINGS At baseline, PAE adult males demonstrated significant higher values of LVSP, LVDP, RPP and ± dp/dt, compared to controls and PAE adult females (p < 0.05), while PAE adult females showed no significant differences compared to controls. In PAE adult males, LVSP, LVDP, RPP and ± dp/dt had significant decreasing trends per phases after I/R, compared to their controls and PAE females, while these decreasing trends were not statistically significant in PAE adult female rats vs. their controls. SIGNIFICANCE The impact of prenatal androgen exposure on adulthood cardiac function and tolerance to I/R is gender dependent, which may be partly explained by different cardiac effects of hyperandrogenism in males versus females. After prenatal androgen exposure, the baseline hemodynamic parameters of the hearts of adult males are increased; although they had less tolerance to I/R, findings however not observed in females.

Abstract
Background The purpose of this study was to investigate the effects of Crocin on oxidative markers (GPx, SOD, MDA) in animal model of demyelination with Ethidium bromide (EB). Methods Female Wistar rats were assigned in to 4 groups; Sham, with no receiving any agent (Sham), Sham Operated group with injection of EB into the brain received no agent (SO), Sham Treatment group with injection of EB and receiving PBS as vehicle and Treatment group with injection of EB and receiving Crocin (100 mg/kg). Demyelination was induced by single dose injection of 10 μl of EB 0.1% into the Cisterna magna of the brain. Crocin was diluted and applied to each animal for 21 days, once per day gavage. The levels of oxidative markers (GPx, SOD and MDA) were measured by related standard kits. Data were analyzed by paired t-test and ANOVA with post hoc test. Results The results showed that crocin decreases the levels of GPx and SOD significantly as well as MDA level after 21 days (α ≤ 0.05). In addition, results showed that there were significant differences in the GPx, SOD and MDA levels between all groups at post treatment phase (α ≤ 0.05). Conclusion It can be concluded that crocin can moderate the level of oxidative markers after demyelination of the brain cells in MS cases. Due to this effect, crocin can be considered as an effective anti-oxidant in management of degenerative nervous system diseases.

Abstract
BACKGROUND AND AIM The association of diabetes mellitus (DM) and poor metabolic control with high incidence of cardiovascular diseases is well established. The aim of this study was to investigate the potential cardioprotective effect of crocin (Crocus sativus L. extract) on diabetic heart dysfunction and to elucidate the mediating molecular mechanisms. METHODS AND RESULTS Streptozotocin (STZ)-induced diabetic rats were treated with two different concentrations of crocin (10 or 20 mg/kg), while isolated cardiac myocytes exposed to 25 mM glucose, were treated with 1 or 10 μM of crocin. Treatment of STZ-diabetic rats with crocin resulted in normalization of plasma glucose levels, inhibition of cardiac hypertrophy and fibrosis, and improvement of cardiac contractile function. Heat Shock Response was enhanced. Myocardial AMPK phosphorylation was increased after treatment with crocin, resulting in normalization of autophagy marker proteins (LC3BII/LC3BI ratio, SQSTM1/p62 and Beclin-1), while the diabetes-induced myocardial apoptosis was decreased. Similar results regarding the effect of crocin on autophagy and apoptosis pathways were obtained in isolated cardiac myocytes exposed to high concentration of glucose. CONCLUSION The results suggest that crocin improves the deteriorated cardiac function in diabetic animals by enhancing the heat shock response, inhibiting apoptosis and normalizing autophagy in cardiac myocytes. Thus, treatment with crocin may represent a novel approach for treating diabetic cardiomyopathy.

Abstract
Ischemia-reperfusion (I/R) injury affects o2-dependent organs including liver, kidneys, heart, brain, and intestine. I/R injury is described as the cellular injury in an organ caused by ischemia and then further aggravated during the reperfusion due to intracellular alterations. It is a process that happens in clinical settings such as organ transplantation, reperfusion after thrombolytic therapy, and coronary angioplasty. Crocus sativus L. known as saffron used in folk medicine for its beneficial effects. It contains multiple bioactive compounds including the crocin, crocetin, picrocrocin, and safranal. Crocin, a water-soluble carotenoid has antitumor, radical scavenging, anti hyperlipidemia and memory improving effects. Moreover, crocin has antioxidant, and protective effects on I/R models in rats at various organs such as heart, brain, kidney, stomach, liver, and kidney as described in detail in this review.

Abstract
Diabetic Nephropathy (DN) is one of the main complications associated with diabetes mellitus. Persistently elevated blood glucose level drives histopathological changes in renal tissues that hinder normal kidney functions. In the current study, crocin; the main bioactive constituent of Crocus sativus was investigated as a reno-protective agent against DN by virtue of its numerous pharmacological activities. Diabetes was induced in male Sprague-Dawely rats through intravenous injection of streptozocin (STZ) (50 mg/kg), DN was confirmed eight weeks post diabetes induction. Daily oral crocin for eight weeks (20 mg/kg) significantly reduced blood glucose level with a significant increase in insulin level. Moreover, crocin improved impaired kidney functions as manifested in reduction of serum creatinine levels, blood urea nitrogen and proteinuria with concomitant increase in urinary creatinine clearance. Furthermore, biomarkers of cell injury and tissue necrosis like LDH activity was significantly reduced, kidney content of NOS significantly declined likewise. In addition, renal antioxidants such as SOD, GSH and serum catalase activity significantly increased with concomitant reduction of kidney MDA; biomarker of oxidative load. Kidney content of toll-like receptors 4 and IL-6 significantly declined with simultaneous suppression of nuclear factor kappa-B (NF-κB/p65) protein expression and immuno-staining in rat renal cortex. Furthermore, crocin inhibited progression of renal fibrosis as seen with reduction of renal hydroxyproline and collagen content, TGF-β immuno-staining and Masson's Trichrome positive tissue. Histopathologically, crocin pretreatment was associated with minimal renal damage with fewer fibrotic lesions. There was a concomitant restoration of renal tubules integrity with preservation of glomerular space area. In conclusion, crocin's ameliorative impact on DN may be attributed to its free radicals scavenging properties, its ability to enhance host antioxidant defense system and its ability to inhibit inflammatory and fibrotic cascades activation.

Abstract
Allergic asthma is a chronic respiratory disease with a prevalent T helper (Th2)-mediated immune reaction. Crocin, the major bioactive constituent of saffron, has been reported in multiple studies to have numerous pharmacological activities, including prominent anti-oxidant activities. In the current study, the anti-asthmatic potential of crocin was evaluated. Adult male Swiss Albino mice were administered 10mg of ovalbumin (OVA) mixed with 1mg of aluminum hydroxide intraperitoneally on days 0 and 7 and were administered crocin (25mg/kg) orally daily for 16days. Asthma progression was associated with significant increase in the lung/body weight index, inflammatory cell counts in bronchoalveolar lavage fluid (BALF), lung total protein content, and serious index of lung permeability, indicating pulmonary edema with accumulation of serous fluids within the lungs. Serum lactate dehydrogenase (LDH) activity and lung malondialdehyde (MDA) content were significantly increased, while lung superoxide dismutase (SOD) activity, reduced glutathione (GSH) levels, and serum and lung catalase activities were significantly decreased. These changes reflect significant pulmonary inflammation with concomitant disturbance of oxidant/antioxidant homeostasis. Moreover, tumor necrosis factor (TNF)-α, interleukin (IL)-4, and IL-13 contents in the lung were also significantly high after OVA sensitization. Crocin treatment significantly alleviated the OVA-induced allergic asthma-associated alterations in inflammatory and oxidative stress biomarkers. Crocin enhanced anti-oxidant defenses, reduced the incidence of oxidative stress, and restored pro-inflammatory cytokines to normal levels. Histopathological analysis showed significant lung improvement in crocin-treated mice. In conclusion, crocin showed a significant protective effect against allergic asthma progression, which was associated with down-regulation of inflammatory cytokine expression and restoration of oxidant/antioxidant homeostasis.

Abstract
The most important conditions associated with hypothyroidism is the cardiac dysfunction. Apelin is an endogenous ligand, involved in energy storage and metabolism which improves cardiac contractility. This study was done to evaluate the effects of apelin, l-Thyroxin (T4) or a combination of both, on cardiac function and mRNA expression of two contractile proteins, α and β myosin heavy chain (α-MHC and β-MHC), in 6-propyl-2-thiouracil (PTU)-induced hypothyroid rats. Forty male Wistar rats were randomly assigned into five groups: Ctrl (Control), and 4 hypothyroid groups (H, HA, HT, and HAT). The Hypothyroid (H) group received 0.05% PTU in the drinking water for six weeks; the next 3 groups, along with PTU, received apelin (HA, 200μg/kg/day, ip), T4 (HT, 20μg/kg/day, gavage), or a combination of both drugs (HAT) for the last 2weeks (weeks 5 and 6). TSH and T4 were measured using ELISA kit. Isolated hearts of animals were perfused in Langendorff apparatus and left ventricular developed pressure, cardiac contractility, heart rate, rate pressure product and perfusion pressure were assessed using PowerLab ADInstruments. In addition α-MHC and β-MHC mRNA expression were evaluated by RT-PCR method in heart tissue. Apelin alone or accompanied by T4 significantly increased cardiac contractility and performance as compared to hypothyroid group. Apelin also significantly increased the alpha-MHC mRNA expression and in the presence of T4 significantly decreased beta-MHC mRNA expression. It seems that apelin alone may improve cardiac function in hypothyroid rats via genomic pathways.

Abstract
Doxorubicin (DOX)-induced cardiotoxicity is well-known as a serious complication of chemotherapy in patients with cancer. It is unknown whether crocin (CRO), main component of Crocus sativus L. (Saffron), could reduce the severity of DOX-induced cardiotoxicity. Therefore, this study was undertaken to assess the protective impact of CRO on DOX-induced cardiotoxicity in rats. The rats were divided into four groups: control, DOX (2mg/kg/48h, for 12days), and CRO groups that receiving DOX as in group 2 and CRO (20 and 40mg/kg/24h, for 20days) starting 4days prior to first DOX injection and throughout the study. Echocardiographic, electrocardiographic and hemodynamic studies, along with histopathological examination and MTT test were carried out. Our findings demonstrate that DOX resulted in cardiotoxicity manifested by decreased the left ventricular (LV) systolic and diastolic pressures, rate of rise/drop of LV pressure, ejection fraction, fractional shortening and contractility index, as compared to control group. In addition, histopathological analysis of heart confirmed adverse structural changes in myocardial cells following DOX administration. The results also showed that CRO treatment significantly improved DOX-induced heart damage, structural changes in the myocardium and ventricular function. In addition, CRO did not affect the in vitro antitumor activity of DOX. Taken together, our data confirm that CRO is protective against cardiovascular-related disorders produced by DOX, and clinical studies are needed to examine these findings in human.

The antioxidant and antiapoptotic effects of crocin pretreatment on global cerebral ischemia reperfusion injury induced by four vessels occlusion in rats. Life Sci 2016; 154:79-86. [PMID: 27117584 DOI: 10.1016/j.lfs.2016.04.028] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Revised: 04/18/2016] [Accepted: 04/21/2016] [Indexed: 12/23/2022]
Abstract
AIMS Cerebral ischemia reperfusion (IR) injury is a process in which oxidative and apoptotic mechanisms play a part. Neuroprotective agents to be found could work out well for the efficient and safe minimization of cerebral IR injury. Crocin is a strong antioxidant agent; however the influence of this agent on the experimental cerebral ischemia model has not been studied extensively and thus it is not well-known. The objective of our study was to investigate the antioxidant, antiapoptotic and protective effects of crocin on the global cerebral IR induced by four-vessel occlusion. MAIN METHODS A total of 30 adult female Sprague-Dawley rats were equally and randomly separated into three groups as follows: sham, IR and IR+crocin (40mg/kg/day orally for 10days). 24h after electrocauterization of bilateral vertebral arteries, bilateral common carotid arteries were occluded for 30min and reperfused for 30min. Oxidative stress parameters (TAS, TOS, OSI), haematoxylin and eosin staining, caspase-3 and hypoxia-inducible factor-1 alpha (HIF-1α) expressions and TUNEL methods were investigated. KEY FINDINGS There was a significant difference between the IR and sham groups by means of OSI level, histopathological scoring, caspase-3, HIF-1α and TUNEL-positive cell parameters. We have also observed that pre-treatment with crocin reduced these parameter levels back to the baseline. SIGNIFICANCE The data obtained from the present study suggest that crocin may exert antiapoptotic, antioxidant and protective effects in IR-mediated brain injury induced by four-vessel occlusion. To the best of our knowledge, this would be the first study to be conducted in this field.

Abstract
Crocus sativus L. (C. sativus), commonly known as saffron, is used as a food additive, preservative, and medicinal herb. Traditionally, it has been used as an alternative treatment for different diseases. C. sativus' medicinal effects are related to its major constituents like crocins, crocetin, and safranal. According to the literature, C. sativus and its constituents could be considered as an effective treatment for neurodegenerative disorders, coronary artery diseases, asthma, bronchitis, colds, fever, diabetes, and so on. Recently, numerous studies have reported such medicinal properties and found that the underlying mechanisms of action may be mediated by antioxidant, inflammatory, and immunomodulatory effects. C. sativus enhances the antioxidant capacity and acts as a free radical scavenger. As an antiinflammatory and immunomodulatory agent, it modulates inflammatory mediators, humoral immunity, and cell-mediated immunity responses. This review highlights in vitro and animal findings regarding antiinflammatory, antioxidant, and immunomodulatory effects of C. sativus and its constituents. Present review found that the C. sativus and its main constituents such as safranal, crocins, and crocetin could be effective against various diseases because of their antioxidant, anti-inflammation, and immunomodulatory effects.

Abstract
OBJECTIVE Crocin is a saffron constituent with a potent anti-oxidant activity. The present study investigated the effects of crocin and insulin treatments (alone or in combination) on cardiac function and pathology in diabetic rats. MATERIALS AND METHODS Diabetes was induced by intraperitoneal (i.p.) injection of streptozotocin (STZ, 50 mg/kg). Thereafter, crocin (5, 10 and 20 mg/kg, i.p.), subcutaneous (s.c.) injection of insulin (4 IU/kg) and their combination were administered for eight weeks. Blood glucose level and whole heart and body weights were measured. Electrocardiography (ECG) was carried out using the lead II. Serum concentrations of lactate dehydrogenase (LDH), creatine kinase-MB isoenzyme (CK-MB), and the heart tissue malodialdehyde (MDA) and superoxide dismutase (SOD) contents were determined. The heart lesions were evaluated by light microscopy. RESULTS STZ decreased body weight and increased whole heart weight/body weight ratio. It also decreased heart rate, and increased RR and QT intervals and T wave amplitude. STZ increased blood glucose, serum LDH and CK-MB levels, augmented heart tissue MDA content, decreased SOD content of heart tissue, and produced hemorrhages, degeneration, interstitial edema, and fibroblastic proliferation in the heart tissue. Crocin (10 and 20 mg/kg, i.p.), insulin (4 IU/kg, s.c.) and their combination (5 mg/kg of crocin with 4 IU/kg of insulin) treatments recovered the ECG, biochemical and histopathological changes induced by STZ. CONCLUSION The results showed cardioprotective effects of crocin and insulin in STZ-induced diabetic rats. The antioxidant and anti-hyperglycemic properties of crocin and insulin may be involved in their cardioprotective actions.

Abstract
OBJECTIVE Oxidative stress damages cells and brings about the pathogenesis of ischemia/reperfusion injury. This study was carried out to investigate the preconditioning and cardio protective potential effects of crocin and vitamin E by the eNOS and iNOS express gene in ischemia/reperfusion in rats. MATERIAL & METHODS Male rats were divided into seven groups, namely: sham, control group and experimental groups treated with crocin(10, 20 and 40 mg/kg), vitamin E (100 mg/kg) and combination of crocin (40 mg/kg) with vitamin E (100 mg/kg) that were gavaged The heart was removed and relocated to a Langendorff apparatus and subjected to global ischemia and then the left ventricular end diastolic pressure (LVEDP) were measured as a hemodynamic parameter. Total RNA was extracted from heart frozen tissues. RT-PCR technique was performed by specific primers designed for nitric oxide gene and the results were assessed by agarose gel electrophoresis. RESULTS Results after ischemia and reperfusion showed that crocin 40 mg/kg produced a significant improvement of LVEDP as a mechanical function (p<0.05), associated with a reduction of iNOS release (p<0.05). The eNOS mRNA levels were significantly higher in crocin-treated 40 mg/kg compared to controls treated by RT-PCR technique. The combination of crocin and vitamin E have shown more effective on the reduction of iNOS release (p<0.01). CONCLUSION In the isolated rat heart, protective effect of crocin, may possibly be explained by regulating eNOS and iNOS expressions. The Results resultsconfirmed the hypothesis that cardioprotective effect of crocin is partly mediated by nitric oxide. This could explain the cardioprotective action of crocin following ischemia and reperfusion.

Picroside Ⅱ inhibits hypoxia/reoxygenation-induced cardiomyocyte apoptosis by ameliorating mitochondrial function through a mechanism involving a decrease in reactive oxygen species production. Int J Mol Med 2014; 35:446-52. [PMID: 25421707 DOI: 10.3892/ijmm.2014.2009] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2014] [Accepted: 11/21/2014] [Indexed: 11/06/2022] Open
Abstract
Reactive oxygen species (ROS)‑induced mitochondrial dysfunction plays an important role in cardiomyocyte apoptosis during myocardial ischemia/reperfusion (I/R) injury. Picroside Ⅱ, isolated from Picrorhiza scrophulariiflora Pennell (Scrophulariaceae), has been reported to protect cardiomyocytes from hypoxia/reoxygenation (H/R)‑induced apoptosis, but the exact mechanism is not fully clear. The aim of the present study was to explore the protective effects of picroside Ⅱ on H/R‑induced cardiomyocyte apoptosis and the underlying mechanism. In the H9c2 rat cardiomyocyte cell line, picroside Ⅱ (100 µg/ml) was added for 48 h prior to H/R. The results showed that picroside Ⅱ markedly inhibited H/R‑induced cardiomyocyte apoptosis. In addition, picroside Ⅱ was also able to decrease the opening degree of mitochondrial permeability transition pore (mPTP), increase the mitochondrial membrane potential, inhibit cytochrome c release from mitochondria to cytosol and downregulate caspase‑3 expression and activity concomitantly with the decreased ROS production. These results suggested that picroside Ⅱ inhibited H/R‑induced cardiomyocyte apoptosis by ameliorating mitochondrial function through a mechanism involving a decrease in ROS production.
