Kidney stones and kidney failure in 2008 has happened "milk" incident,
several provinces in the country due to consumption of infant milk powder
melamine was added after emergence. But their clinical toxicity mechanism of
how, but it has been unclear. Recently, Shijiazhuang Kidney Disease Hospital
study found that melamine-induced renal failure in infants with intestinal
bacterial metabolism are closely
According to reports, some intestinal bacteria, especially bacteria of the
genus Klebsiella, the nitrogen-containing compound having a metabolic (also
called nitrogen fixation) The ability to metabolism in the intestinal tract of
melamine, cyanuric acid and converted to its gradual degradation. Melamine and
cyanuric acid is very low toxicity, but easily combined with each other to form
crystals, these two substances into the blood circulation in the renal tubules
with uric acid to form macromolecular complexes like stones, blocking tubules,
resulting in kidney toxicity. Accordingly, the medical center research group
proposed conversion of the intestinal bacterial metabolism and toxicity of
melamine correlation hypothesis and confirmed animal testing.
The researchers pointed out that people in their daily lives on diet,
metabolism, and biological effects of drugs there are significant individual
differences, and these individual differences may result from differences
largely intestinal microflora. Related study found that less than one percent of
infants and young children in the consumption of milk containing melamine
melamine-induced renal toxicity appear and urinary system diseases, suggesting
that part of the reason for the occurrence of toxicity in infants, because they
contain a high abundance of gut melamine bacteria capable of metabolizing degree
Klebsiella bacteria such as sake; while only about 1% of the baby's body has
Klebsiella, and after taking infant formula proportion of infants suffering from
kidney toxicity fit just right.
