TL;DR: The results show that p-coumaric acid could be considered a potential immunosuppressive agent in treating autoimmune inflammatory diseases like rheumatoid arthritis.
Abstract: In this study, p-coumaric acid was evaluated for its immunomodulatory and anti-inflammatory properties in vivo. The immunomodulatory effect of p-coumaric acid (100 mg/kg body weight) was assessed by evaluating its effect on cell-mediated immune responses (delayed type hypersensitivity reaction), serum immunoglobulin levels, and macrophage phagocytic index in rats. The anti-inflammatory effects of p-coumaric acid (100 mg/kg body weight) were investigated by examining its effect on expression of tumor necrosis factor (TNF-α) in synovial tissue by immunofluorescence confocal microscopy and circulating immune complexes in serum of adjuvant-induced arthritic rats. The increased cell-mediated immune responses and macrophage phagocytic index observed in control rats were significantly reduced (p < 0.05) upon treatment with p-coumaric acid implying its immunosuppressive property, whereas serum immunoglobulin levels were found to be increased in p-coumaric acid treated control rats. p-coumaric acid also showed significant (p < 0.05) anti-inflammatory effects in adjuvant-induced arthritic rats by effecting a decrease in the expression of inflammatory mediator TNF-α and circulating immune complexes. Indomethacin was used as a reference drug for anti-inflammatory studies. Thus, our results show that p-coumaric acid could be considered a potential immunosuppressive agent in treating autoimmune inflammatory diseases like rheumatoid arthritis.

TL;DR: The aqueous suspension of Withania somnifera root powder showed potent inhibitory activity towards the complement system, mitogen induced lymphocyte proliferation and delayed-type hypersensitivity reaction, thus it could be a candidate for developing as an immunosuppressive drug for the inflammatory diseases.

TL;DR: Investigation of the hepatoprotective and antioxidant effects of gallic acid in paracetamol‐induced liver damage in mice found it to be a good source of anti-inflammatory and antioxidant properties.
Abstract: Objectives The aim of this research paper was to investigate the hepatoprotective and antioxidant effects of gallic acid in paracetamol-induced liver damage in mice. Methods In the present study, the hepatoprotective and antioxidant effects of gallic acid were evaluated against paracetamol-induced hepatotoxicity in mice and compared with the silymarin, a standard hepatoprotective drug. The mice received a single dose of paracetamol (900 mg/kg body weight i.p.). Gallic acid (100 mg/kg body weight i.p.) and silymarin (25 mg/kg body weight i.p.) were administered 30 min after the injection of paracetamol. After 4 h, liver marker enzymes (aspartate transaminase, alanine transaminase and alkaline phosphatase) and inflammatory mediator tumour necrosis factor-alpha (TNF-α) were estimated in serum, while the lipid peroxidation and antioxidant status (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-S-transferase and glutathione) were determined in liver homogenate of the control and experimental mice. Key findings Increased activities of liver marker enzymes and elevated TNF-α and lipid peroxidation levels were observed in mice exposed to paracetamol (P < 0.05), whereas the antioxidant status was found to be depleted (P < 0.05) when compared with the control group. However gallic acid treatment (100 mg/kg body weight i.p.) significantly reverses (P < 0.05) the above changes by its antioxidant action compared to the control group as observed in the paracetamol-challenged mice. Conclusions The results clearly demonstrate that gallic acid possesses promising hepatoprotective effects.

TL;DR: The importance of oxidative stress in the body growth and development as well as proteomic and genomic evidences of its relationship with disease development, incidence of malignancies and autoimmune disorders, increased susceptibility to bacterial, viral, and parasitic diseases are discussed.
Abstract: Oxidative stress is a normal phenomenon in the body. Under normal conditions, the physiologically important intracellular levels of reactive oxygen species (ROS) are maintained at low levels by various enzyme systems participating in the in vivo redox homeostasis. Therefore, oxidative stress can also be viewed as an imbalance between the prooxidants and antioxidants in the body. For the last two decades, oxidative stress has been one of the most burning topics among the biological researchers all over the world. Several reasons can be assigned to justify its importance: knowledge about reactive oxygen and nitrogen species production and metabolism; identification of biomarkers for oxidative damage; evidence relating manifestation of chronic and some acute health problems to oxidative stress; identification of various dietary antioxidants present in plant foods as bioactive molecules; and so on. This review discusses the importance of oxidative stress in the body growth and development as well as proteomic and genomic evidences of its relationship with disease development, incidence of malignancies and autoimmune disorders, increased susceptibility to bacterial, viral, and parasitic diseases, and an interplay with prooxidants and antioxidants for maintaining a sound health, which would be helpful in enhancing the knowledge of any biochemist, pathophysiologist, or medical personnel regarding this important issue.

TL;DR: Animal studies have revealed the promising in vivo therapeutic effect of antioxidants on liver diseases, and various factors that cause oxidative stress in liver and effects of antioxidants in the prevention and treatment of liver diseases were summarized, questioned, and discussed.
Abstract: A complex antioxidant system has been developed in mammals to relieve oxidative stress. However, excessive reactive species derived from oxygen and nitrogen may still lead to oxidative damage to tissue and organs. Oxidative stress has been considered as a conjoint pathological mechanism, and it contributes to initiation and progression of liver injury. A lot of risk factors, including alcohol, drugs, environmental pollutants and irradiation, may induce oxidative stress in liver, which in turn results in severe liver diseases, such as alcoholic liver disease and non-alcoholic steatohepatitis. Application of antioxidants signifies a rational curative strategy to prevent and cure liver diseases involving oxidative stress. Although conclusions drawn from clinical studies remain uncertain, animal studies have revealed the promising in vivo therapeutic effect of antioxidants on liver diseases. Natural antioxidants contained in edible or medicinal plants often possess strong antioxidant and free radical scavenging abilities as well as anti-inflammatory action, which are also supposed to be the basis of other bioactivities and health benefits. In this review, PubMed was extensively searched for literature research. The keywords for searching oxidative stress were free radicals, reactive oxygen, nitrogen species, anti-oxidative therapy, Chinese medicines, natural products, antioxidants and liver diseases. The literature, including ours, with studies on oxidative stress and anti-oxidative therapy in liver diseases were the focus. Various factors that cause oxidative stress in liver and effects of antioxidants in the prevention and treatment of liver diseases were summarized, questioned, and discussed.
