crocin and Body-Weight

Cisplatin (CDDP) has been widely used in cancer therapy, but it has been linked to side effects such as nephrotoxicity. Crocin is a carotenoid found in crocus and gardenia flowers that has been shown to have anti-oxidant properties, inhibit tumor growth, and provide neuroprotection. The purpose of this study was to investigate the protective effect of crocin against CDDP-induced nephrotoxicity in a mouse model. Kunming mice were administered orally with crocin for 7 days at the dose of 6.25 mg/kg and 12.5 mg/kg per body weight daily and were injected with CDDP via intraperitoneal route at the dose of 10 mg/kg per body weight. Using commercial kits, the oxidative stress markers glutathione, malondialdehyde, catalase, glutathione peroxidase, and superoxide dismutase were measured in the kidneys of mice. Immunohistochemistry was used to assess the levels of p53, cleaved caspase-3, and phospho-p38 mitogen-activated protein kinase in the kidneys. Crocin significantly reduced CDDP-induced changes in serum creatinine and blood urea nitrogen levels, according to the findings. Crocin reduced malondialdehyde levels and increased glutathione, glutathione peroxidase, catalase, and superoxide dismutase levels in CDDP-induced lipid peroxidation. Crocin also significantly inhibited p38 mitogen-activated protein kinase activation, p53 expression, and caspase-3 cleavage. In conclusion, crocin protects against CDDP-induced oxidative stress and nephrotoxicity by attenuating the activation of p38 mitogen-activated protein kinase and caspase-3 cleavage.

Side effects of cisplatin (CIS) such as testicular toxicity restrict its clinical use. Instead, evidence indicates that crocin (CR) has synergistic anti-cancer potential with CIS and exhibited beneficial effects on CIS-induced hepatorenal damage. The aim of this study was to investigate the protective potential of CR against CIS-induced testicular toxicity in rats.. Fifty adult male Wistar rats randomly assigned to five equal groups including control, CIS, and CIS plus CR at doses of 6.25 mg/kg (CIS + CR6.25), 25 mg/kg (CIS + CR25), and 100 mg/kg (CIS + CR100). CIS and CIS + CR groups received a single intraperitoneally (i.p.) injection of CIS (7 mg/kg). CR (6.25-100 mg/kg i.p.) injections were started three days before the CIS injection and continued once a day for up to 13 days. On the 14th day, all animals were sacrificed and their blood samples and testes were removed for biochemical and histological analyses.. These findings demonstrated that CR co-treatment could prevent CIS-induced testicular toxicity in rats.

The present study was aimed to investigate anticancer activity of crocin against cervical carcinoma and bio-assessment and toxicological evaluation in male albino rats. Effect of crocin on cell viability (anticancer activity) was determined against cervical carcinoma cells. Chronic effect of crocin on body weight changes, serum enzymes, serum biochemical markers, lipid peroxidation, hematological markers and DNA damage in male albino rats were determined. Cell survival rate was reduced 98.4, 95.7, 87.2, 81.1 and 73.1% at 25, 50, 75, 100 and 125 mg/l of crocin respectively. Cell viability was reduced 97.1, 96.4, 85.5, 78.4 and 70.2% at 25, 50, 75, 100 and 125 mg/l of crocin respectively. Crocin reduced body weight significantly at 30 and 60th day. Alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine, bilirubin, albumin and total protein were decreased, while glucose, cholesterol, TG, and GSH were increased. Hemoglobin (Hb), white blood cells (WBC), lymphocytes, neutrophil and packed cell volume (PCV) were altered following crocin treatment. Necrosis, fibrosis, mononuclear infiltration, angiogenesis and DNA fragmentation were also noted. Taking all these data together, it is suggested that the crocin could be a potential antitumor agent against cervical carcinoma. However, the altered histological, biochemical and hematological markers may lead to an adverse effect on the cellular metabolism and physiological activity.

Saffron (Crocus sativus) is a widely used food additive for its color and taste. Crocin and safranal are two main components of this plant. Numerous studies are underway to introduce saffron and its active ingredients as pharmacological agents. Safety assessments of these compounds are important parts of this endeavor. In this study, the effects of crocin and safranal administrations during embryogenesis have been investigated in mice. A total of 75 BALB/c pregnant mice were divided into six experimental and control groups. Four experimental groups received intraperitoneal injection of crocin (200 mg/kg or 600 mg/kg) daily or safranal (0.075 ml/kg or 0.225 ml/kg) on gestational days (GDs) 6 to 15. Control groups received normal saline or paraffin as solvents of crocin and safranal. Dams were dissected on GD18 and embryos were collected. Routine maternal and fetal parameters were recorded. Macroscopic observation of external malformations was also performed. Fetuses were then selected for double skeletal staining with alizarin red and alcian blue. All experimental groups caused significant decrease in length and weight of fetuses when compared with the control groups and revealed malformations such as minor skeletal malformations, mandible and calvaria malformations, and growth retardation. Minor skeletal malformations were the most commonly observed abnormality, which were statistically significant when compared with the control groups (p < 0.05). The severities of malformations were comparable in the crocin- and safranal-treated groups. This study suggests that crocin or safranal can induce embryonic malformations when administered in pregnant mice. Due to the wide use of saffron, further elaborate studies to understand the malformation mechanisms of these ingredients are recommended.

Crocin is the only water soluble carotenoid in nature, and it has a known powerful antioxidant activity. The aim of this work was to investigate the hypoglycemic and hypolipidemic effects of crocin in streptozotocin (STZ)-induced type 2 diabetic rats. Neonatal male Wistar rats (2-5 days old) were randomly divided into five groups. Three groups were intraperitoneally injected with STZ (90 mg/kg body weight). Among them, two groups were treated with intraperitoneal injection of crocin (50 or 100 mg/kg), and the third group was treated with vehicle only. Two control groups were also considered, and one of them was treated with crocin. After 5 months, their blood and urine samples were collected, and the animals were sacrified. The results indicate a significant lower body weight (P < 0.001) and abnormal parameters in the diabetic rats compared with the normal group. An administration of both doses of crocin significantly decreased the levels of serum glucose, advanced glycation end products, triglyceride, total cholesterol, and low-density lipoprotein and increased the high-density lipoprotein in the diabetic rats. The treatments were also effective in decreasing HbA1c and microalbuminuria, as well as homeostatic model assessment for insulin resistance as a measure of insulin resistance in the diabetic rats.

In the present study, the effects of an ethanol and aqueous extract of saffron Crocus sativus and its constituents safranal and crocin on the stress-induced reduction in food intake, weight gain and anorexic time in mice were investigated. Male albino mice (20-25 g) were irregularly exposed to a trial of electroshock stress for 7 days. Then, the anorexic time as well as the animal's food intake and weight were recorded. In addition, blood samples were obtained on days 1 and 7 for corticosterone determination. Intraperitoneal (i.p.) administration of the aqueous but not the ethanol extract (10, 50 and 100 mg/kg) significantly reduced the anorexic time. The results were similar for crocin (1, 5 and 10 mg/kg; i.p.). In addition, a reduction in weight gain was observed in the controls as well as in the groups that received alcohol extract or safranal. However, this was not observed in animals treated with aqueous extract or crocin. The plasma corticosterone level did not increase in the aqueous extract and crocin treated animals. It can be concluded that the saffron aqueous extract and its constituent crocin reduce side effects of electroshock stress in mice.

The aim of the present study was to evaluate the hypolipidemic and antioxidant potential of saffron and its active constituent, crocin, in hyperlipidemic rats. The animals fed either with normal fat diet or high fat diet were administered orally saffron (25, 50, and 100 mg/kg) or crocin (4.84, 9.69, and 19.38 mg/kg) in their respective groups for five consecutive days. Biochemical estimations of triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), alkaline phosphatase (ALP), aspartate transaminase (AST), alanine aminotransferase (ALT), malondialdehyde (MDA), glutathione peroxidase enzyme activity (GSHPx), total glutathione (GSH), and oxidized glutathione (GSSG) in serum and superoxide dismutase (SOD), catalase (CAT), thiobarbituric acid reactive species (TBARS), ferric reducing/antioxidant power (FRAP), and total sulfhydryl (SH) groups in liver tissue homogenate were carried out. Both saffron and crocin were effective in decreasing the elevated levels of TG, TC, ALP, AST, ALT, MDA, GSHPx, GSH, and GSSG in serum and increasing SOD, CAT, FRAP, and SH values in liver tissue with reduction in TBARS. The saffron was found to be superior to crocin indicating the involvement of other potential constituents of saffron apart from crocin for its synergistic behavior of quenching the free radicals and ameliorating the damages of hyperlipidemia.

The pancreatic lipase inhibitors were isolated from the fructus of Gardenia jasminoides ELLIS, and their antihyperlipidemic activities were measured. Gardeniae fructus (GF) water extract inhibited pancreatic lipase activity. Crocetin and crocin were isolated from GF water extract as inhibitors of pancreatic lipase with an IC50 value of 2.1 and 2.6 mg/ml (triolein as a substrate). Crocin and crocetin significantly inhibited the increase of serum TG level in corn oil feeding-induced triglyceridemic mice, as well as that of serum triglyceride and total and LDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. These compounds also showed hypolipidemic activity in hyperlipidemic mice induced by high cholesterol, high fat or high carbohydrate diets for 5 weeks. The results suggest that the hypolipidemic activity of GF and its component crocin may be due to the inhibition of pancreatic lipase and crocin, and its metabolite, crocetin, can improve hyperlipidemia.
