Ferulago angulata extract improves the quality of buck spermatozoa post-thaw and counteracts the harmful effects of diazinon and lead

During cryopreservation, spermatozoa are exposed to chemical or physical stress that has adverse effects on the quality of mammalian spermatozoa. Recently, much attention has been paid to environmental contaminants (ECs) in livestock, because of their detrimental effects on livestock productivity and fertility. ECs like diazinon (DZN) and lead acetate (LA) are considered ubiquitous and induced oxidative stress, which decreases spermatozoa quality. Since Ferulago angulata extract (FAE) has antioxidant properties, the present study investigated the effect of FAE supplementation in a freezing extender, in the presence or absence of DZN + LA, during cryopreservation, on the quality and fertility ability of buck spermatozoa after thawing. Pooled ejaculates were diluted with a freezing extender and supplemented with FAE (0.002%, w/v) in the presence or absence of DZN (100 μM) + LA (12.5 μM). Post-thaw spermatozoa parameters, ROS production, fertilization ability, and developmental competence of oocytes inseminated with FAE/DZN + LA treated spermatozoa were calculated. The results demonstrated that FAE improves cryopreserved spermatozoa motility, viability, membrane integrity, fertilizability, and developmental competence, and reduced spermatozoa ROS production in the presence or absence of DZN + LA. Besides, FAE significantly restored the adverse effects of DZN + LA exposure during cryopreservation on inner cell mass (ICM) count, trophectoderm (TE) cell count, total cell number (TCN), and the ratio between ICM to TCN. In conclusion, FAE on its own resulted in an improvement in the buck spermatozoa's quality and fertility. Therefore, the addition of FAE, as a natural antioxidant to buck semen extender, can increase spermatozoa cryotolerance and post-thaw resistance even when exposed to ECs.

Ferulago angulata extract ameliorates epididymal sperm toxicity in mice induced by lead and diazinon

BACKGROUND

The potential toxicity that results from environmental xenobiotics is not completely known. Increasing levels of heavy metals and the use of organophosphate pesticides (OPs) and their co-existence in the environment could be associated with an increasing incidence of male reproductive system disorders in humans and animals. Ferulago angulata is a dietary source of phenolic compounds with reported health benefits.

OBJECTIVE

This study was conducted to investigate whether an extract of Ferulago angulata could protect adult male NMRI mice against reproductive toxicity induced by lead acetate (PbAc), diazinon (DZN), or PbAc + DZN.

MATERIALS AND METHODS

Adult male NMRI mice were exposed to either 0.5% PbAc in drinking water, DZN (3 mg/kg/day, intraperitoneal [i.p.] injection), or PbAc + DZN in the presence or absence of 400 mg/kg/day Ferulago angulata hydroalcoholic extract (FAE) that was administered via gavage for 6 weeks.

RESULTS

Chronic exposure to PbAc, DZN, and PbAc + DZN decreased sperm quality, sperm chromatin maturity and integrity, increased oxidative stress and lipid peroxidation, and could reduce male fertility indices. Co-administration of FAE could reduce these negative effects.

CONCLUSION

The Ferulago angulata extract should be considered as a useful natural extract for the treatment of male infertility, especially in males exposed to conditions which induce reproductive toxicity.

Nephroprotective effect of Ferulago angulata flowers on N-nitrosodimethylamine-induced nephrotoxicity in rats and its phytochemical profile

The present study was designed to assess the phytochemical content of Ferulago angulata (FA) and possible in vivo nephroprotective effect of FA administration on trace elements, minerals, MDA and GSH in kidney and liver tissue samples, serum vitamin (α-tocopherol, retinol, cholecalciferol, phylloquinone), TSA, and LSA in a rat model of DMN-induced nephrotoxicity. In the study, Wistar albino rats were assigned to six groups: Control (0.9% NaCl), (DMN 10 mg/kg), (FA 150 mg/kg), (DMN + FA 150 mg/kg), (FA 300 mg/kg), and (DMN + FA 300 mg/kg). Rats were intraperitoneally given DMN for the first 7 days. Renal injury caused by DMN was proved by the histopathological alterations. The FA (300 mg/kg) treatment significantly normalized Se, Cr, Ca levels in liver and Co level in kidney tissue samples. These observed positive effects are due to the phytochemical content of the plant. The flower extract of FA (300 mg/kg) can be used for the prevention of kidney damage. PRACTICAL APPLICATIONS: Ferulago angulata flowers are used in traditional medicine for treat kidney and liver digestive system diseases. This species is endemic taxa of the family Apiaceae, which has been used both as food and therapeutics because of their phytochemical composition. In this study, the phenolic characterization of FA flower was used to a new RP-HPLC method, as well as the biological activity of FA flower and possible in vivo nephroprotective effect of FA flowers on trace elements, minerals, MDA and GSH in kidney and liver tissue samples and vitamins, TSA, and LSA in serum samples a rat model of DMN-induced nephrotoxicity. It was found that high level of phenolic compounds (chlorogenic acid, vanillic acid, 2-hydroxycinnamic acid) present in the flower extract of F. angulata has positive effects and antioxidant properties. Due to its phenolic content, FA flower extract could protect for kidney damage and can be used as antioxidants in the food additive and pharmaceutical industry.

Antioxidant properties of Ferulago angulata and its hepatoprotective effect against N-nitrosodimethylamine-induced oxidative stress in rats

CONTEXT

Ferulago angulata (Schlecht.) Boiss. (Apiaceae) (FASB) is used to treat liver diseases and has been used both as food and therapeutics by many cultures for thousands of years because of the natural antioxidant compounds.

OBJECTIVE

This study determines antioxidant properties of FASB flowers, the levels of minerals and vitamins, and also, evaluates the hepatoprotective effect of flowers against N-nitrosodimethylamine (NDMA) induced on liver tissue by assessing antioxidant enzymes and histopathological parameters in Wistar albino rats.

MATERIALS AND METHODS

In the study, the rats were divided into six groups of ten. Control, untreated animals were given 0.9% NaCl. Rats were intraperitoneally given NDMA (10 mg/kg) for the first 7 days. FASB methanol extract (150 and 300 mg/kg) was administered orally for 21 days.

RESULTS

α-Tocopherol, retinol, ascorbic acid, total antioxidant activity, phenolic and flavonoid contents of FASB were 0.70 ± 0.13, 0.29 ± 0.03 μg/g, 139.32 ± 7.06 μg/100 g, 171.61 ± 6.05 mM ascorbic acid/g, 90.47 ± 4.11 mg GA/g and 37.39 ± 2.85 mg QE/g. DPPH and hydroxyl radical scavenging activity was obtained IC₅₀ 67.34 ± 4.14 and 64.87 ± 4.68 μg/mL, respectively.

DISCUSSION AND CONCLUSION

The results of the study indicated that FASB flowers contain high levels of vitamins, minerals, total antioxidant activity, phenolics and flavonoids. Due to the positive effect on significant changes in antioxidant enzymes of liver tissue and histopathological examination, it is thought that the plant could be used as a hepatoprotective.

Stabilization of soybean oil during accelerated storage by essential oil of ferulago angulata boiss

This study has been considered effect of Ferulago angulata essential oil on stabilizing soybean oil during accelerated storage. The essential oil was extracted by Clevenger-type apparatus. For analysis of the essential oil, GC/MS was used. Main components of the essential oil were monoterpene and sesquiterpene hydrocarbons. The essential oil of F. angulata at four concentrations, i.e. 125 (SBO-125), 250 (SBO-250), 500 (SBO-500) and SBO-Mixture (60 ppm TBHQ +60 ppm essential oil) were added to preheated refined soybean oil. TBHQ was used at 120 ppm as standard besides the control. Antioxidant activity index (AAI), free fatty acid (FFA) content, peroxide value (PV) and p-anisidine value (p-AnV) were served for appreciation of efficacy of F. angulata in stabilization of soybean oil. Results from different tests showed that SBO-mixture had highest effect and followed by SBO-TBHQ, SBO-250, SBO-125, SBO-500 and Ctrl. These results reveal F. angulata is a strong antioxidant and can be used instead of synthetic antioxidant.

Ferulago angulata activates intrinsic pathway of apoptosis in MCF-7 cells associated with G1 cell cycle arrest via involvement of p21/p27

Ferulago angulata is a medicinal plant that is traditionally known for its anti-inflammatory and antiulcer properties. The present study was aimed to evaluate its anticancer activity and the possible mechanism of action using MCF-7 as an in vitro model. F. angulata leaf extracts were prepared using solvents in the order of increasing polarity. As determined by MTT assay, F. angulata leaves hexane extract (FALHE) revealed the strongest cytotoxicity against MCF-7 cells with the half maximal inhibitory concentration (IC₅₀) value of 5.3±0.82 μg/mL. The acute toxicity study of FALHE provided evidence of the safety of the plant extract. Microscopic and flow cytometric analysis using annexin-V probe showed an induction of apoptosis in MCF-7 by FALHE. Treatment of MCF-7 cells with FALHE encouraged the intrinsic pathway of apoptosis, with cell death transducing signals that reduced the mitochondrial membrane potential with cytochrome c release from mitochondria to cytosol. The released cytochrome c triggered the activation of caspase-9. Meanwhile, the overexpression of caspase-8 suggested the involvement of an extrinsic pathway in the induced apoptosis at the late stage of treatment. Moreover, flow cytometric analysis showed that FALHE treatment significantly arrested MCF-7 cells in the G₁ phase, which was associated with upregulation of p21 and p27 assessed by quantitative polymerase chain reaction. Immunofluorescence and the quantitative polymerase chain reaction analysis of MCF-7 cells after treatment with FALHE revealed an upregulation of Bax and a downregulation of Bcl-2 proteins. These findings proposed that FALHE suppressed the proliferation of MCF-7 cells via cell cycle arrest and the induction of apoptosis through intrinsic pathway.
