proanthocyanidin b5/inflammation

Peanut skin (Arachis hypogaea L., Fabaceae) is an abundant source for polyphenols, such as proanthocyanidin oligomers. To determine whether proanthocyanidin has beneficial effects on skin, we tested for inhibitory activity of proanthocyanidins isolated from peanut skin on inflammatory cytokine

BACKGROUND The aim of this study was to assess the possible protective effect of proanthocyanidin against cerulein-induced acute pancreatic inflammation (AP) and oxidative injury. METHODS Sprague-Dawley rats were pretreated with proanthocyanidine (100 mg/kg, orally) or saline 15 min before cerulein

BACKGROUND Antioxidants have been suggested to alleviate the pathophysiological features of asthma, and grape seed proanthocyanidin extract (GSPE) has been reported to have powerful antioxidant activity. OBJECTIVE This study was performed to determine whether GSPE has a therapeutic effect on

Proanthocyanidins (PA) have been proven to suppress inflammation and promote osteogenic differentiation. However, whether PA could promote osteogenic differentiation of human periodontal ligament fibroblasts (HPDLFs) in inflammatory environment is unclear. Here, HPDLFs were stimulated by tumor

BACKGROUND The anti-inflammatory effects of proanthocyanidins (PACs), isolated from blackcurrant (Ribes nigrum L.) leaves, were analysed using carrageenin-induced paw oedema and carrageenin-induced pleurisy in rats. RESULTS Pretreatment of the animals with PACs (10, 30, 60 and 100 mg/kg, i.p.)

Asthma is characterized by airway inflammation and airway remodeling. Our previous study revealed that grape seed proanthocyanidin extract (GSPE) could inhibit asthmatic airway inflammation and airway hyper-responsiveness by down-regulation of inducible nitric oxide synthase in a murine model of

BACKGROUND Anti-inflammatory and skin hydration properties of a dietary supplement and 2 topical formulations (Anthogenol) with oligomeric proanthocyanidins were investigated. METHODS Forty-two subjects were randomized into 2 groups: one taking the dietary supplement (100 mg/day) and the other

Phenolic compounds, which are secondary plant metabolites, are considered an integral part of the human diet. Physiological properties of dietary polyphenols have come to the attention in recent years. Especially, proanthocyanidins (ranging from dimers to decamers) have demonstrated potential

Excessive chronic alcohol consumption enhances brain oxidative and inflammatory stress, resulting in cognitive deficit. This study investigated the potential alleviating effects of proanthocyanidins (PACs) on ethanol-induced cognitive impairment and stress in brain regions including the prefrontal

Recent evidence strongly suggests that oxidative stress due to redox imbalance is causally associated with inflammatory processes and various diseases including diabetes. We examined the effects of proanthocyanidin from persimmon peel, using both oligomers and polymers, against oxidative stress with

Chronic autoimmune inflammation, which is commonly observed in rheumatoid arthritis (RA), disrupts the delicate balance between bone resorption and formation causing thedestruction of the bone and joints. We undertook this study to verify the effects of natural grape-seed proanthocyanidin extract

BACKGROUND Positive effects of pistachio nut consumption on plasma inflammatory biomarkers have been described; however, little is known about molecular events associated with these effects. OBJECTIVE We studied the anti-inflammatory activity of a hydrophilic extract from Sicilian Pistacia L. (HPE)

Grape-seed proanthocyanidins (GSPs) have been shown to function as an anti-oxidant and anti-inflammatory agent with little toxicity in vivo and in vitro. However, little is known about their anti-inflammatory properties and mechanisms of action. The specific focus being its effects on the MAP

Interactions between dendritic cells (DCs) and environmental, dietary and pathogen antigens play a key role in immune homeostasis and regulation of inflammation. Dietary polyphenols such as proanthocyanidins (PAC) may reduce inflammation, and we therefore hypothesized that PAC may suppress

In the present study, we aimed to investigate the molecular mechanisms and prophylactic effects of grape seed proanthocyanidin (GSP) on lipopolysaccharide (LPS)-stimulated human hepatic stellate cells (HSCs). Cell counting and MTT assays were used to assess cell viability in the absence or presence
