毒性
|
A nitrogenous end
product and the principal excretory product of purine metabolism in mammals. In birds and reptiles, it is the principal end
product of nitrogen metabolism in general. Defects in uric acid
metabolism and excretion appear to be associated with a number of disease states, and it frequently occurs as a component
of renal calculi. It has not been associated closely with toxic
insults except in the case of lead poisoning. Lead causes an
elevation in blood uric acid concentration (uric acidemia) and
a decrease in uric acid excretion.

生产方法 |
1.取干燥鸡粪悬浮于24倍量水中,加入适量氢氧化钙后静置。沉淀完全后分出上清液,沉淀中再加水,用硝酸调节pH值至3,静置至沉淀完全。分出上清液,沉淀物再悬浮在水中,以氢氧化钙调节pH值至12~12.5,过滤后滤液以硝酸调pH值至3,析出物过滤、干燥后即为尿酸粗品。 |
