BACKGROUND & AIMS: Blood transfusion therapy is lifesaving for individuals with β-thalassemia major (β-TM). Iron burden following blood transfusion is the main cause of oxidative stress (OS) and organ dysfunction in these patients. The aim of this study was to evaluate the effects of silymarin on serum antioxidant and oxidative status in patients with β-TM. METHODS: A crossover, randomized controlled trial was performed on 82 thalassemia patients. In two periods of 12 weeks, patients received 420mg silymarin (divided into three equal 140-mg daily doses) and placebo...

Hepatitis C virus (HCV) is a major public health problem being the most common cause of chronic liver disease in Egypt. HCV-induced decompensated liver cirrhosis patients have a median survival of 2 years even with currently used new treatments. Silymarin is the most commonly used herbal product in chronic liver disease for its anti-inflammatory, antiviral, antioxidant, and antifibrotic effects. The aim of this study was to assess the effects of silymarin in high dose on the clinical and biochemical status of chronic HCV-associated decompensated liver cirrhosis...

The liver is an essential organ for the detoxification of exogenous xenobiotics, drugs and toxic substances. The incidence rate of non-alcoholic liver injury increases due to dietary habit change and drug use increase. Our previous study demonstrated that Ecklonia stolonifera (ES) formulation has hepatoprotective effect against alcohol-induced liver injury in rat and tacrine-induced hepatotoxicity in HepG2 cells. This present study was designated to elucidate hepatoprotective effects of ES formulation against carbon tetrachloride (CCl₄)-induced liver injury in Sprague Dawley rat...

Milk thistle (Silybum marianum) is a medicinal plant that has been used for thousands of years as a remedy for a variety of ailments. The main component of S. marianum fruit extract (silymarin) is a flavonolignan called silybin, which is not only the major silymarin element but is also the most active ingredient of this extract, which has been confirmed in various studies. This compound belongs to the flavonoid group known as flavonolignans. Silybin's structure consists in two main units. The first is based on a taxifolin, the second a phenyllpropanoid unit, which in this case is conyferil alcohol...

The combined use of different P-glycoprotein (P-gp) inhibitors may be a relevant approach to the synergistic and safer inhibition of the P-gp-mediated drug efflux. Herein, we aimed to explore dual combinations of the flavonoids baicalein, (-)-epigallocatechin gallate, kaempferol, quercetin and silymarin to reverse the interference of P-gp on the intracellular accumulation of antiepileptic drugs (AEDs). The intracellular accumulation of rhodamine 123 (a classic P-gp substrate) and of several commonly used AEDs (carbamazepine, phenytoin, oxcarbazepine) or their metabolites (carbamazepine-10,11-epoxide and licarbazepine) was evaluated in MDCK-MDR1 cells in the presence and absence of individual flavonoids and their combinations...

Silibinin is the major active component of silymarin, extracted from medicinal plant Silybum marianum. Silibinin has potent antibacterial activity; however, the exact mechanism underlying its activity has not been elucidated. Here, we investigated the novel mechanism of silibinin against Escherichia coli. Time-kill kinetic assay showed that silibinin possess a bactericidal effect at minimal inhibitory concentration (MIC) and higher concentrations (two and four-fold MIC). At the membrane depolarization and increased intracellular Ca²⁺ levels were observed, considered as characteristics of bacterial apoptosis...

Silymarin has been used in the treatment of a number of liver diseases for a long time, but its efficacy in preventing triptolide induced acute hepatotoxicity has not been reported previously. The present study aimed to assess the protective effect of silymarin against triptolide (TP)-induced hepatotoxicity in rats. Rats were orally administrated with silymarin (50, 100 and 200 mg/kg) for 7 days and received intraperitoneal TP (2 mg/kg) on the day 8. Hepatic injuries were comprehensively evaluated in terms of serum parameters, morphological changes, oxidative damage, inflammation and apoptosis...

Bacterial cellulose (BC) is a biopolymer composed of nanofibers which has excellent film-forming ability. However, BC do not have antibacterial or antioxidant activity, thus limiting the applicability of BC for food and biomedical applications. In this study, flavonoid silymarin (SMN) and zein were assembled into spherical SMN-Zein nanoparticles that could be effectively adsorbed onto BC nanofibers. SMN-Zein nanoparticles greatly changed the wettability and swelling property of BC films due to the formation of nanoparticles/nanofibers nanocomposites...

Acute respiratory distress syndrome (ARDS) is a deadly disease and lacks effective treatments. Inflammation and oxidative stress play key roles in ARDS development. We aimed to evaluate the efficacy of pretreatment of silymarin, which has capacities of anti-inflammatory and anti-oxidative stress, in ARDS. We used lipopolysaccharide (LPS) to generate an ARDS rat model, which was pretreated with silymarin. Lung wet/dry ratio and broncho-alveolar lavage fluid (BALF) analyses were performed. Histological changes of the lungs were evaluated using hematoxylin and eosin staining...

Background: Penthorum chinense Pursh (Penthoraceae, PCP), a well-known Miao ethnomedicine, has been traditionally used to treat several liver-related diseases, such as jaundice and viral hepatitis. The aims of the present study were to evaluate the probable properties of the aqueous extract of PCP on carbon tetrachloride (CCl4)-induced acute liver injury in mice. Methods: C57BL/6 mice were orally administered an aqueous extract of PCP (5.15 and 10.3 g/kg BW) or silymarin (100 mg/kg) once daily for 1 week prior to CCl4 exposure...

Silibinin, an active constituent of silymarin extracted from milk thistle, has been previously reported to confer protection to the adult brain against neurodegeneration. However, its effects against epileptic seizures have not been examined yet. In order to investigate the effects of silibinin against epileptic seizures, we used a relevant mouse model in which seizures are manifested as status epilepticus, induced by kainic acid (KA) treatment. Silibinin was injected intraperitoneally, starting 1 day before an intrahippocampal KA injection and continued daily until analysis of each experiment...

The aim of this study was to evaluate the hepatoprotective effect of silymarin in diets contaminated or not with aflatoxin B1 (AFB1) on the productive performance and serum biochemical profile of Japanese quail (Coturnix coturnix japonica) in the laying phase. A total of 240 12-week-old Japanese quail was used in a completely randomized design in a 3 × 2 factorial scheme (additives x contaminated or not with AFB1 - 1,500 μg/kg), totaling 6 treatments and 5 replicates of 8 birds each. The additives used were silymarin (500 g/ton), adsorbent (1 kg/ton), and a control diet (without additive)...

Chemoprevention is a practical approach to reduce the risk of various cancers including colorectal cancer (CRC). The goal is to reduce the incidence of pre-neoplastic adenomatous polyps and prevent its progression to CRC. Curcumin and silibinin prevent intestinal polyp formation in mice. Curcumin sensitizes silymarin to exert synergistic anticancer activity in colon cancer cells. Patients presenting with multiple colorectal adenomatous polyps (MCRA) have a high lifetime risk for CRC. We present a 57-year-old man with MCRA, without deleterious germline APC or MYH mutations...

Oxidative stress and inflammation are involved in paraquat-induced cytotoxicity. Silymarin can exert a potent antioxidative and anti-inflammatory effect in various pathophysiological processes. The aim of this current study is to explore the protective effect and potential mechanism of silymarin in paraquat-induced macrophage injury. Cells were pretreated with different doses of silymarin for 3h before exposure to paraquat. At 24h after exposure to paraquat, the paraquat-induced cytotoxicity to macrophage was measured via the MTT assay and LDH release...
