Aminoguanidine and curcumin may reduce tumor activity

The up regulation of gut mucosal cytokines such as tumor necrosis factor (TNF)-α and oxidative stress have been related to inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD). This study investigated an immune-mediated model of colitis.

 

TNF-α injected intraperitonally to mice induced a dose-dependent recruitment of neutrophils into abdominal mesentery. The leukocytes influx induced by TNF-α (10 μg kg(-1) body weight) increased by 3 fold liver and colon damage scores. TNF-α-colitis was characterized by hemorrhagic edemas and crypt abscesses massively infiltrated by inflammatory cells, namely neutrophils. Moreover, TNF-α-toxicity resulted in liver steatosis and foci of necrosis infiltrated by Kupffer cells and neutrophils in parenchyma and around the centrilobular veins. The involvement of oxidative stress was evaluated using aminoguanidine (AG) as selective inhibitor of inducible NO synthase (iNOS) and curcumin (Cur), the polyphenolic antioxidant of turmeric (Curcuma longa L.).

 

TNF-α-toxicity led to significant increase in myeloperoxidase (MPO, an index of neutrophils infiltration), nitrites (stable nitric oxide metabolites) and malondialdehyde (MDA, a marker of lipid peroxides) levels and cell apoptosis in liver and colon. AG and Cur treatments significantly attenuated the hallmarks of oxidative stress, neutrophils influx and ROS-related cellular and histological damages, in TNF-α-treated mice.

 

Taken together, our results provide insights into the role of phagocytes-derived oxidants in TNF-α-colitis in mice. Cur and AG, by inhibiting neutrophils priming and iNOsynthase could be effective against oxidative bowel damages induced in IBD by imbalanced gut immune response.

Curcumin + Omega-3 Curbed Breast Cancer - Vital Choice

Curcumin + Omega-3 Curbed Breast Cancer - Vital Choice | Longevity science | Scoop.it
Lab experiments and preliminary clinical studies indicate that curcuminoids support immune and brain health in uniquely powerful ways. And earlier this month, the authors of a review paper painted this positive picture of the substantial clinical evidence on curcumin:“Extensive clinical trials over the past quarter century have addressed the … efficacy of [curcumin and] promising effects have been observed in patients with various pro-inflammatory diseases including cancer, cardiovascular disease, arthritis … [and more than 25 others]. (Gupta SC et al. 2013).

Nutrition Journal | Abstract | Diverse effects of a low dose supplement of lipidated curcumin in healthy middle aged people

Curcumin extracts of turmeric are proposed to produce health benefits. To date, human intervention studies have focused mainly on people with existing health problems given high doses of poorly absorbed curcumin.

 

In this small study, absorbable low doses of curcumin were seen to produce positive effects in healthy middle aged people. The results of the small study indicate that curcumin helps to protect health heart, brain, and immune system function.

Protect your heart with Turmeric

Protect your heart with Turmeric | Longevity science | Scoop.it

Curcumin (extracted from the spice turmeric) is currently one of the most studied natural remedies.

 

A recent controlled study, published in the American Journal of Cardiology involved administering curcumin (or sugar pills) to bypass patients.

 

Those given curcumin pills had significantly lower levels of inflammation and oxidative stress indicators, as well as a 65% reduced risk of heart attack following the bypass surgery.
