BACKGROUND: Aflatoxin contamination of foods is a worldwide problem. Chronic
aflatoxin exposure is associated with kidney damage. Curcumin is a herbal agent,
used in medicine with a wide range of beneficial therapeutic effects. OBJECTIVE:
to evaluate the effect of curcumin against experimentally induced aflatoxicosis
on the renal cortex of adult male albino rats. MATERIALS AND METHODS: Forty adult
male rats were included and they were divided equally into 4 groups (10 rats
each): Group I (control group), group II (Curcumin group): The rats received
curcumin (200 mg/kg b.w.) orally by gastric tube for 5 days/week, group III
(Aflatoxin B1 group): The rats received aflatoxin B1 (250 ?g/kg b.w./day) orally
by gastric tube 5 days/week for 4 weeks, group IV (Aflatoxin B1 and Curcumin
group): The rats received aflatoxin and curcumin orally by gastric tube 5
days/week for 4 weeks. Kidney specimens were prepared and sections were stained
with hematoxylin and eosin, Masson's trichrome, Periodic acid Schiff,
immunohistochemical detection of desmin and Bcl2. RESULTS: The tubules of group
III showed degenerative and necrotic changes with disruption of basal lamina.
There was a significant decrease Bcl2 expression in the tubules, but the
glomeruli showed an enlargement with dilation of their capillaries lumina in some
areas, while the other areas showed glomerular atrophy with obliteration of their
capillaries lumina. There was a significant increase in desmin expression in the
glomerular cells. The interstitium showed hemorrhage and cellular infiltration.
Group IV showed improvement of the histological and immunohistochemical changes
described before. CONCLUSION: Aflatoxin B1 has deleterious effects of on the
histological structure of the rat's renal cortex and curcumin minimized these
effects as it has antioxidant, anti-inflammatory and antiapoptotic activities. We
advise eating nutritious diets that contain sufficient amounts of curcumin and
regulation must implement to avoid the presence of aflatoxins in high
concentrations in human food.
