Propolis Protects Kidneys from Aluminum Toxicity

Propolis is the natural protector for humans and animals. It's been proven in numerous studies to protect the body from commonly occuring illnesses, as well as more toxic situations, such as this example. You'll find even more references to its protective nature with other internal organs such as the liver and the intestines in this blog...

Role of Propolis (Bee Glue) in Improving Histopathological Changes of the Kidney of Rat Treated with Aluminum Chloride
EnvironToxicol, 2012 Nov 22

Humans are frequently exposed to aluminum from various food additives, therapeutic treatments and the environment, and it can be potentially toxicThis study is aimed to elucidate the protective effects of propolis against aluminum chloride (AlCl(3) )-induced histopathological and immunohistochemical changes in kidney tissues of rats. 

Sixty Wistar Albino male rats (average weight 250-300 g) were divided into three equal groups. The first served as a negative control. The second received AlCl(3) (34 mg/kg bw, 1/ 25 LD 50). The third were administered AlCl(3) (34 mg/kg bw, 1/ 25 LD 50) plus propolis (50 mg/kg bw). Doses were given once daily via a gavage for 8 weeks every day.

The results showed that shrunken glomeruli, intraglomerular congestion, loss of apical microvilli, degeneration of mitochondria and widened rough endoplasmic reticulum were also observed in the Proximal Convoluted Tubules of these animals. Treatment with propolis ameliorated the harmful effects of AlCl(3) ; this was also proved histopathologically by the noticeable improvement in the renal tissues. There were also significant variations in the expressed of ki-67 and p53 proteins.

It can be concluded that propolis may be promising as a natural therapeutic agent in AlCl(3) -induced renal toxicity and oxidative stress in rat kidneys.
