Hyperammonemia in horses has most frequently been associated with decreased clearance of NH 4 + secondary to severe hepatic disease with subsequent development of hepatic encephalopathy. More recently, a different syndrome of increased blood NH 4 + concentrations in the absence of hepatic disease has been recognized clinically and documented in the equine literature. The increased NH 4 + concentrations are thought to originate from the gastrointestinal tract, and the syndrome is therefore referred to as intestinal HA. Intestinal HA is presumed to be caused by either overgrowth of urease-producing bacteria in the large or small intestine or increased absorption of NH 4 + from the gastrointestinal tract because of altered permeability of the intestinal barrier. 我自己翻译的是：马高氨血症经常和严重的肝脏疾病及随后发展的肝性脑病继发引起的NH4+清除减弱有着密切的关系。最近，在没有肝脏疾病情况下，血液中NH4+浓度增加引起的不同综合征已经通过临床诊断记录在相关马的文献中。NH4+浓度的增加是在肠道内进行的，因此该综合征称为肠道高氨血症。肠道高氨血症可能是由于在不同大小肠道内脲酶产生菌的过度繁殖造成的，或者由于来自胃肠道内NH4+吸收增多造成的，从而改变了肠道屏障的通透性。 |
