    PMID:  PLoS One. 2021 ;16(2):e0246292. Epub 2021 Feb 4. PMID: 33539403 Abstract Title:  Tai Chi practitioners have lower fall risks under dual-task conditions during stair descending. Abstract:  Stairs are among the most hazardous locations, and stair descending contributes to a high risk of falls among the elderly under dual-task (DT) conditions. The purpose of this study was to determine whether the practitioners of Tai Chi (TC), one type of mind-body exercise, have lower fall risks under DT conditions during stair descending, compared with their no-exercise (NE) counterparts. Fifteen TC practitioners with at least 10 years of experience in TC and fifteen NE participants were recruited in this study. They were asked to descend a six-step staircase under single-task (ST) and DT conditions. An eight-camera motion analysis system and two force plates were used for data collection. Results showed group by DT interactions in walking velocity (p = 0.016) and center of mass-center of pressure inclination angle (COM-COP IA) in the anteroposterior directions (p = 0.026). Group effects observed with foot clearance (p = 0.031), trunk (p = 0.041) and head (p = 0.002) tilt angles, and COM-COP IA in the mediolateral (p = 0.006) directions.

    PMID:  Saudi J Biol Sci. 2020 Sep ;27(9):2444-2451. Epub 2020 Jun 30. PMID: 32884428 Abstract Title:  In silico authentication of amygdalin as a potent anticancer compound in the bitter kernels of family Rosaceae. Abstract:  Amygdalin a naturally occurring compound, predominantly in the bitter kernels of apricot, almond, apple and other members of Rosaceae family. Though, amygdalin is used as an alternative therapy to treat various types of cancer but its role in cancer pathways has rarely been explored yet. Therefore, present study was intended with the aim to investigate the alleged anti-cancerous effects of amygdalin specifically on PI3K-AKT-mTOR and Ras pathways of cancer in human body. Computational modelling and simulation techniques were used to assess the effect of amygdalin on PI3K-AKT-mTOR and Ras pathways using different level of dosage. It was observed that amygdalin had direct and substantial contribution to regulate PI3K-mTOR activities on threshold levels while the other caner pathways were effected indirectly. Consequently, amygdalin is a down-regulator of a cancer within a specified amount and contribute considerably to reduce various types of cancer in human. Furthermore,andanalyses of amygdalin could be of helpful to authenticate its pharmacological effects. read more Read more

    PMID:  Stem Cells Int. 2020 ;2020:8811963. Epub 2020 Sep 7. PMID: 32963548 Abstract Title:  Amygdalin Promotes Fracture Healing through TGF-/Smad Signaling in Mesenchymal Stem Cells. Abstract:  Chondrogenesis and subsequent osteogenesis of mesenchymal stem cells (MSCs) and angiogenesis at injured sites are crucial for bone fracture healing. Amygdalin, a cyanogenic glycoside compound derived from bitter apricot kernel, has been reported to inhibit IL-1-induced chondrocyte degeneration and to stimulate blood circulation, suggesting a promising role of amygdalin in fracture healing. In this study, tibial fractures in C57BL/6 mice were treated with amygdalin. Fracture calluses were then harvested and subjected to radiographic, histological, and biomechanical testing, as well as angiography and gene expression analyses to evaluate fracture healing. The results showed that amygdalin treatment promoted bone fracture healing. Further experiments using MSC-specific transforming growth factor- (TGF-)receptor 2 conditional knockout (KO) mice () and C3H10 T1/2 murine mesenchymal progenitor cells showed that this effect was mediated through TGF-/Smad signaling. We conclude that amygdalin could be used as an alternative treatment for bone fractures. read more Read more

PMID: 29674281 Abstract Title:  Effects of tocotrienol from Bixa orellana (annatto) on bone histomorphometry in a male osteoporosis model induced by buserelin. Abstract:  INTRODUCTION: Osteoporosis is a debilitating skeletal side effect of androgen deprivation therapy based on gonadotropin-releasing hormone (GnRH) agonist in men. Tocotrienol from Bixa orellana (annatto) has been demonstrated to offer protection against osteoporosis by exerting anabolic effects on bone. Thus, it may prevent osteoporosis among GnRH agonist users.OBJECTIVE: This study aimed to determine the effectiveness of annatto-tocotrienol on the bone turnover markers and bone histomorphometry in a model of male osteoporosis induced by buserelin (a GnRH agonist).METHODS: Forty-six three-months-old male Sprague-Dawley rats (three months old; 300-350 g) were randomly divided into six groups. The baseline control group (n = 6) was sacrificed at the onset of the study. The normal control group (n = 8) received corn oil (the vehicle of tocotrienol) orally daily and normal saline (the vehicle of buserelin) subcutaneously daily. The buserelin control (n = 8) received corn oil orally daily and subcutaneous buserelin injection 75 μg/kg/day daily. The calcium control (n = 8) received 1% calcium in drinking water and subcutaneous buserelin injection 75 μg/kg/day. The remaining rats were treated with two different treatments,… Read more

PMID: 30369954 Abstract Title:  Hydroalcoholic Extract and Ethyl Acetate Fraction ofLeaves Decrease the Inflammatory Response toSubsp.. Abstract:  The incidence of infections caused by rapidly growing mycobacteria (RGM), especiallysubsp.(), is increasing worldwide. Severe infections are associated with abscess formation and strong inflammatory response. This study evaluated the antimicrobial and anti-inflammatory activities of a hydroalcoholic extract (BoHE) and ethyl acetate fraction (BoEA) ofleaves. Antimicrobial activity was evaluated by broth microdilution to determine the minimum inhibitory (MIC) and the minimum bactericidal (MBC) concentrations. Cytotoxicity was evaluated using erythrocytes and RAW 264.7 cells. Nitric oxide (NO) was assayed in stimulated RAW 264.7 cells, and inflammatory cell migration and acute toxicity were evaluated in a-induced peritonitis mouse model. The compounds present in BoEA were identified by high performance liquid chromatography and mass spectrometry (HPLC-MS). The MIC and MBC values were 2.34 mg/mL and 37.5 mg/mL for BoHE and 0.39 mg/mL and 6.25 mg/mL for BoEA. The extracts did not induce significant toxicity in erythrocytes and RAW 264.7 cells. High levels of NO induced bywere decreased by treatment with both extracts. The anti-inflammatory activity was confirmedby significant reduction of the cell migration to the… Read more

PMID: 33192531 Abstract Title:  Amygdalin Attenuates Atherosclerosis and Plays an Anti-Inflammatory Role in ApoE Knock-Out Mice and Bone Marrow-Derived Macrophages. Abstract:  Amygdalin, the main component of Prunus persica (L.) Stokes, has been used to treat atherosclerosis in mouse model due to its anti-inflammatory role. However, the underlying mechanism remains poorly understood. This study aimed to evidence the influence of amygdalin on high-fat diet-induced atherosclerosis in ApoE knock-out (ApoE) mice, and unravel its anti-inflammatory mechanism. ApoEmice fed with high-fat diet for eight weeks were randomly divided into four groups and injected with amygdalin at the concentration of 0.08 or 0.04 mg/kg for 12 weeks. Additionally, bone marrow-derived macrophages were intervened with oxidized low-density lipoprotein (oxLDL) or lipopolysaccharide plus various concentrations of amygdalin for further exploration. Body weight, serum lipid profiles and inflammatory cytokines were detected by ELISA, gene expression by RT-PCR, plaque sizes by Oil Red O, lymphatic vessels of heart atrium and Tnfα production by immunofluorescence staining. MAPKs, AP-1 and NF-κB p65 pathways were also explored. Amygdalin decreased body weight, serum lipids, plaque size, lymphatic vessels and inflammatory cytokines (Il-6, Tnfα), Nos1 and Nos2, and increased Il-10 expression in ApoEmice. In oxLDL-induced bone… Read more

PMID: 33253723 Abstract Title:  Amygdalin alleviates renal injury by suppressing inflammation, oxidative stress and fibrosis in streptozotocin-induced diabetic rats. Abstract:  AIMS: To explore the protective efficacies and potent mechanism of amygdalin on high glucose-cultured renal cell HBZY-1 in vitro and streptozotocin (STZ)-induced diabetic nephropathy (DN) rat in vivo.MAIN METHODS: The cellar proliferation and generation of ROS in high-glucose cultured HBZY-1 cell were assessed by MTT and DCFH-DA assay, respectively. The fasting blood glucose levels, renal function and inflammation indexes as well as oxidative stress markers in STZ-induced diabetic rats were all measured. The histologic renal section was stained with Mason and periodic acid-Schiff (PAS) method. Immunohistochemistry and western blotting methods were applied to assess expression levels of extracellular matrix (ECM), epithelial-mesenchymal transition (EMT)-related as well as TGF-β1/Smad signaling pathway-related proteins.KEY FINDINGS: Firstly, amygdalin significantly suppressed the excessive cell proliferation and ROS generation in HBZY-1 cells cultured with high glucose. The hyperglycemia, 24 h-UP excretion, BUN and Scr of DN rats were significantly attenuated after the chronic treatment of amygdalin. Moreover, MDA, SOD, IFN-γ and IL-12 levels in kidney tissues were all effectively reduced. Besides, amygdalin can suppress the ECM accumulation… Read more

PMID: 33296784 Abstract Title:  Amygdalin inhibits TGFβ1-induced activation of hepatic stellate cells (HSCs) in vitro and CCl-induced hepatic fibrosis in rats in vivo. Abstract:  The activation of hepatic stellate cells (HSCs) has been considered one of the major events in hepatic fibrosis. Amygdalin has been used to treat cancers and alleviate pain; however, its role and mechanism in HSC activation and hepatic fibrosis remain unclear. In the present study, transforming growth factor-beta 1 (TGF-β1) stimulated the activation of HSCs, as indicated by significantly increased alpha-smooth muscle actin (α-SMA), desmin, collagen I, and tissue inhibitor of metalloproteinase-1 (TIMP-1) protein levels. Amygdalin treatment dramatically suppressed TGF-β1-induced HSC proliferation and activation. Moreover, amygdalin treatment also reduced the TGF-β1-induced secretion of cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), platelet-derived growth factor (PDGF), and chemokine (C-C motif) ligand 2 (CCL2), as well as the phosphorylation of Smad2, Smad3, and p65. In the CCl-stimulated liver fibrosis rat model, amygdalin treatment improved liver fibrosis and liver damage by reducing focal necrosis, collagen fiber accumulation, and the protein levels ofα-SMA, desmin, collagen I, and TIMP-1 in hepatic tissue samples and reducing serum alanine transaminase (ALT) and… Read more

PMID: 33435880 Abstract Title:  Amygdalin promotes the activity of T cells to suppress the progression of HBV-related hepatocellular carcinoma via the JAK2/STAT3 signaling pathway. Abstract:  BACKGROUND: Hepatitis B virus (HBV) infection is a high-risk factor of hepatocellular carcinoma (HCC). Cellular immune responses are essential for HCC development, and the CD4+ and CD8+ T subtypes are identified as the primary anti-tumor immune cells. In the study, we investigated the effect and mechanism of amygdalin in the cellular immune response in HBV-related HCC and HCC progression.METHODS: The cell proliferation was examined by MTT analysis. Cells metastasis ability was detected by Invasion and migration assays. Quantification of apoptotic cells was performed with Flow cytometer assay. The protein levels of p-STAT3, STAT3, p-JAK2, JAK2, caspase-3, cleaved caspase-3 were detected by performing immunoblotting assays.RESULTS: We demonstrate that amygdalin treatment could rescue the HBV-T cell viability and IFN-γ and TNF-αproduction. In HBV-T cells, the MFI levels of CD8are lower than that in NC-T cells. Moreover, the phosphorylation levels of STAT3 and JAK2 are higher in HBV-T cells, compared to those in NC-T cells, and then reduced by amygdalin treatment. Co-culture with HBV-T cells could… Read more

PMID: 33448586 Abstract Title:  Cardioprotective potential of amygdalin against angiotensin II induced cardiac hypertrophy, oxidative stress and inflammatory responses through modulation of Nrf2 and NF-κB activation. Abstract:  Heart failure (HF) and cardiac hypertrophy is an unfavorable outcome of pathological cardiac remodeling and represents the most important contributing factor for HF and cardiac hypertrophy. Amygdalin (AMG) is a cyanogenic glycoside derived from bitter almonds. Accumulating evidences have highlighted their pharmacological potentials against various diseases. However, there is no report delineating the potential of AMG against angiotensin (Ang II) induced cardiac injuries. Thus, the present study was performed to explore whether AMG could ameliorate Ang II induced cardiomyopathies and thereby ascertain the underlying mechanisms thereof. To this end, H9c2 cells were treated with Ang II and thereafter treated with various concentration of AMG and finally the cardio-protective effects of AMG were analyzed through Western blotting, immunofluorescence, and insilico analysis. Our results showed that the cardiomyocyte cell size, inflammatory markers and cytokines(pNF-κB, TNF-α, iNOS and COX-2) were markedly increased following Ang II treatment; nevertheless, treatment with AMG led to considerable decrement in the Ang II induced enlargement of the cardiomyocytes, and attenuate the… Read more

PMID: 33733877 Abstract Title:  The Combination of Amygdalin with Some Anticancer, Antiparasitic, and Antigout Drugs Against MG63, Saos2, SW1353, and FL Cells. Abstract:  Osteosarcoma has a poor prognosis and survival rate due to inadequate chemotherapy, high recurrence ability, high metastasis potential, and almost no radiotherapy being applied. One of the strategies to solve these problems is to develop the pharmacologically active plant metabolite, amygdalin, in combination therapeutic systems. In this project, the antiproliferative effects of amygdalin alone and in binary or ternary combinations with some anticancer drugs (cisplatin, 5-fluorouracil, oxaliplatin, and camptothecin), antiparasitic drugs (metronidazole and miltefosine), and an antigout drug (colchicine) were examined using human bone osteosarcoma cell lines (MG-63 and Saos2), the chondrosarcoma cell line (SW1353), and the normal human cell line (FL). Known half-maximal inhibitory concentration values of the drugs were taken into consideration, and the recommended combination ratios were used in the Chou-Talalay method. The strong synergistic effect commonly seen in the combination of amygdalin with miltefosine, metronidazole, camptothecin, colchicine, oxaliplatin, 5-fluorouracil, and cisplatin dual drug indicates that these combinations can be used in cancer treatment. The synergistic effect caused by amygdalin decreases toxicity by… Read more

    PMID:  Mol Med Rep. 2021 Jun ;23(6). Epub 2021 Apr 26. PMID: 33899114 Abstract Title:  Mangiferin inhibits cell migration and angiogenesis via PI3K/AKT/mTOR signaling in high glucose‑ and hypoxia‑induced RRCECs. Abstract:  Mangiferin is a prominent active component that can be derived from several traditional herbs, includingL.,Bge., and (L.) DC., which displays antidiabetic properties. Diabetic retinopathy (DR), a serious complication caused by diabetes, is the leading cause of blindness. The present study aimed to evaluate the beneficial effects of mangiferin on high glucose (HG)/hypoxia‑induced rat retinal capillary endothelial cell (RRCEC) angiogenesis, as well as the underlying mechanisms. To establish anmodel of DR, RRCECs were exposed to 30 mM glucose and hypoxia. Following treatment with different doses of mangiferin (0.05, 0.1 or 0.2 M), RRCEC viability, migration and angiogenesis were assessed by performing Cell Counting Kit 8, immunofluorescence, wound healing, Transwell and tube formation assays. Western blotting was conducted to evaluate protein expression levels. Furthermore, LY294002 and IGF‑1, an inhibitor and activator of the PI3K/AKT/mTOR signaling pathway, respectively, were used to verify the potential mechanisms underlying mangiferin. The results demonstrated that mangiferin notably inhibited HG/hypoxia‑induced RRCEC migration and angiogenesis. HG/hypoxia‑induced upregulation of hypoxia‑inducible factor‑1α, vascular endothelial growth factor, matrix metallopeptidase (MMP)2 and MMP9 expression levels and the phosphorylation of… Read more

PMID: 33919084 Abstract Title:  Anti-Arthritic and Anti-Inflammatory Potential ofExtract Fractions: An In Silico, In Vitro and In Vivo Approach. Abstract:  The fruits ofhave traditionally been used for the management of rheumatism in the northeast region of India. The present study explores the probable anti-arthritis and anti-inflammatory potential offruit extract's ethanolic fraction (EtoH-F). To support this study, we first approached the parameters in silico by means of the active constituents of the plant (beta amyrin, beta sitosterol, oleonolic acid and co-crystallised ligands, i.e., SPD-304) via molecular docking on COX-1, COX-2 and TNF-α. Thereafter, the absorption, distribution, metabolism, excretion and toxicity properties were also determined, and finally experimental activity was performed in vitro and in vivo. The in vitro activities of the plant extract fractions were evaluated by means of parameters like 1,1-Diphenyl-2- picrylhydrazyl (DPPH), free radical-reducing potential, albumin denaturation, and protease inhibitory activity. The in vivo activity was evaluated using parameters like COX, TNF-α and IL-6 inhibition assay and arthritis score in Freund Adjuvant (CFA) models at a dose of 400 mg/kg b.w. per day of different fractions (hexane, chloroform, alcoholic). The molecular docking assay was performed on COX-1,… Read more

    PMID:  Biochem Biophys Res Commun. 2009 Dec 25 ;390(4):1372-6. Epub 2009 Nov 3. PMID: 19891958 Abstract Title:  Bixin regulates mRNA expression involved in adipogenesis and enhances insulin sensitivity in 3T3-L1 adipocytes through PPARgamma activation. Abstract:  Insulin resistance is partly due to suppression of insulin-induced glucose uptake into adipocytes. The uptake is dependent on adipocyte differentiation, which is controlled at mRNA transcription level. The peroxisome proliferator-activated receptor (PPAR), a ligand-regulated nuclear receptor, is involved in the differentiation. Many food-derived compounds serve as ligands to activate or inactivate PPAR. In this study, we demonstrated that bixin and norbixin (annatto extracts) activate PPARgamma by luciferase reporter assay using GAL4-PPAR chimera proteins. To examine the effects of bixin on adipocytes, 3T3-L1 adipocytes were treated with bixin or norbixin. The treatment induced mRNA expression of PPARgamma target genes such as adipocyte-specific fatty acid-binding protein (aP2), lipoprotein lipase (LPL), and adiponectin in differentiated 3T3-L1 adipocytes and enhanced insulin-dependent glucose uptake. The observations indicate that bixin acts as an agonist of PPARgamma and enhances insulin sensitivity in 3T3-L1 adipocytes, suggesting that bixin is a valuable food-derived compound as a PPAR ligand to regulate lipid metabolism and to ameliorate metabolic syndrome. read more Read more

    PMID:  J Agric Food Chem. 2012 Dec 5 ;60(48):11952-8. Epub 2012 Nov 21. PMID: 23145898 Abstract Title:  Bixin activates PPARα and improves obesity-induced abnormalities of carbohydrate and lipid metabolism in mice. Abstract:  Peroxisome proliferator-activated receptorα (PPARα) is a ligand-activated transcription factor that regulates the expression of the genes involved in fatty acid oxidation. PPARα activators induce fatty acid oxidation in the liver, thereby improving lipid and carbohydrate metabolism in obese mice. In this study, the dietary cis-carotenoids bixin and norbixin, which are commonly used in the food coloring industry, were found to activate PPARα by luciferase reporter assays using GAL4/PPARα chimeric and full-length PPARα systems. Treatment with bixin and norbixin induced the mRNA expression of PPARα target genes involved in fatty acid oxidation in PPARα-expressing HepG2 hepatocytes. In obese KK-Ay mice, bixin treatment suppressed the development of hyperlipidemia and hepatic lipid accumulation. In the livers of bixin-treated mice, the mRNA levels of PPARα target genes related to fatty acid oxidation were up-regulated. Moreover, bixin treatment also improved obesity-induced dysfunctions of carbohydrate metabolism, such as hyperglycemia, hyperinsulinemia, and hypoadiponectinemia. Glucose tolerance test and insulin tolerance test revealed that glucose intolerance and insulin resistance in KK-Ay obese mice were attenuatedby the treatment… Read more

    PMID:  Curr Pharm Biotechnol. 2013 ;14(9):785-91. PMID: 24372269 Abstract Title:  Bixin action in the healing process of rats mouth wounds. Abstract:  Oral lesions that manifest as ulcer lesions are quite common and can cause discomfort to the patient. Searching for drugs to accelerate the healing of these lesions is nonstop process. Bixin is a molecule found in annatto (urucum) seeds and is considered a viable therapeutic option to treat such lesions due to its anti-inflammatory, anti-oxidant, and healing properties. Therefore, the present study aimed to evaluate the effect of the bixin solution in the ulcer healing process in the oral mucosa of rats. Ulcers were induced with punches of 0.5 cm in the middle of the dorsum of the tongue of 64 Wistar rats. The animals were randomly divided into 8 groups, in which 4 groups were treated with saline solution, while the other 4 were treated with the bixin solution. The animals were sacrificed in the periods 2, 7, 14, and 21 days after the beginning of the treatment. The species were histologically processed and stained with hematoxylin/eosin and picrosirius. Fibroblasts, reepithelialization, and wound contraction could be observed, as could the quantification of neutrophils, macrophages, plasma cells, lymphocytes, and… Read more

PMID: 25066077 Abstract Title:  Bixin loaded solid lipid nanoparticles for enhanced hepatoprotection--preparation, characterisation and in vivo evaluation. Abstract:  In the present study, a natural antioxidant drug, bixin was loaded into solid lipid nanoparticles using trimyristin and glycerol monostearate as different lipid matrices and soya and egg lecithin as stabilizers. Developed bixin SLNs were characterized including in vitro drug release and in vivo evaluation of hepatoprotective activity using Wistar rats. Bixin SLNs were prepared by hot homogenisation followed by ultrasonication technique. The particle size ranged from 135.5-352.8 nm with PDI 0.185-0.572. Zeta potential of bixin SLNs was -17.9 to -36.5 mV. Bixin was successfully incorporated into SLNs with entrapment efficiency above 99% and loading efficiency maximum 17.96%. There was no interaction of bixin with selected lipids TM and GMS, confirmed by FTIR studies. DSC studies revealed that preparation method did not change crystallinity of bixin and TM whereas GMS crystallinity was reduced. In vitro drug release studies in Sorensen buffer, pH 7.7 exhibited initial burst effect followed by a sustained release of bixin. Drug release kinetic studies showed that the release was first order diffusion controlled and the n-values… Read more

    PMID:  Biol Res. 2014 Sep 29 ;47:49. Epub 2014 Sep 29. PMID: 25299839 Abstract Title:  Protective effect of bixin on carbon tetrachloride-induced hepatotoxicity in rats. Abstract:  BACKGROUND: The liver is an important organ for its ability to transform xenobiotics, making the liver tissue a prime target for toxic substances. The carotenoid bixin present in annatto is an antioxidant that can protect cells and tissues against the deleterious effects of free radicals. In this study, we evaluated the protective effect of bixin on liver damage induced by carbon tetrachloride (CCl4) in rats.RESULTS: The animals were divided into four groups with six rats in each group. CCl4 (0.125 mL kg(-1) body wt.) was injected intraperitoneally, and bixin (5.0 mg kg(-1) body wt.) was given by gavage 7 days before the CCl4 injection. Bixin prevented the liver damage caused by CCl4, as noted by the significant decrease in serum aminotransferases release. Bixin protected the liver against the oxidizing effects of CCl4 by preventing a decrease in glutathione reductase activity and the levels of reduced glutathione and NADPH. The peroxidation of membrane lipids and histopathological damage of the liver was significantly prevented by bixin treatment.CONCLUSION: Therefore, we can conclude that the protective effect of… Read more

PMID: 25702177 Abstract Title:  The antiatherogenic effect of bixin in hypercholesterolemic rabbits is associated to the improvement of lipid profile and to its antioxidant and anti-inflammatory effects. Abstract:  Hypercholesterolemia and oxidative stress have been implicated in the pathophysiology of atherosclerosis and coronary artery disease. We investigated whether the carotenoid bixin (BIX) may reduce oxidative damage, inflammatory response, and the atherosclerotic lesion induced by hypercholesterolemia in rabbits. Rabbits received regular chow (control) or a hypercholesterolemic diet (0.5% cholesterol) alone or supplemented with BIX (10, 30 or 100 mg/kg body weight, b.w.) or simvastatin (15 mg/kg b.w.) for 60 days. Treatment with BIX or simvastatin reduced the atherosclerotic lesions in cholesterol-fed rabbits (up to 55 and 96% reduction, respectively). This protective effect of BIX was accompanied by decrease in the levels of tumor necrosis factor alpha by 15%, interleukin 6 by 19%, lipid peroxidation by 60%, non-high-density lipoprotein cholesterol (non-HDL-C) by 37%, and triglycerides by 41%. BIX increased by 160% the HDL-C levels and decreased by 67% the atherogenic index of hypercholesterolemic rabbits. In atherosclerotic rabbits, the non-protein thiol groups content and the activity of the antioxidant enzymes superoxide dismutase, catalase,… Read more
