ABSTRACT
Aim of the study: to assess the effect of Quercetin (Q), catechin (CAT) and rich food of them supplementation on immune system in rats.
Materials & Methods: 36 Rats were allocated in 6 groups, first group (6 rats) served as (-ve) negative control group and fed on basal diet, while the second main group (30 rats) drinked polluted water with cadmium chloride (CD) 40mg/k.g for 40 days (to induced immunity inhibition) and fed on basal diet only. Then rats were divided equally to four groups (2, 3, 4, 5, 6) and fed on basal diet only (positive control) or with Q commercial at 45mg swallowed orally, red onions as a natural source Q by 45 mg, CAT commercial at 7.5mg Swallowed orally or green tea as a natural source CAT by 7.5 mg respectively, treatments were for 21 days as mentioned.
Conclusion: Consumption Q and CAT from natural and commercial sources is very useful as its protective effect from immunity disorders has and reduce deleterious effects of cadmium chloride in rats.
