Most mammals, including dogs, synthesize vitamin C in the liver. We measured the plasma concentration of vitamin C to assess the body vitamin C status in 15 dogs with a portosystemic shunt (PSS). The plasma biochemical parameters indicated liver abnormalities in all the dogs. In contrast, the plasma concentration of vitamin C ranged from 2.21 to 9.03 mg/L in the 15 dogs and was below the reference range (3.2 to 8.9 mg/L) in only 2 dogs. These findings suggest that vitamin C status is not impaired in dogs with PSS.
包括狗在内的大多数哺乳动物在肝脏中合成维生素C。我们测量了15只患有门体分流（PSS）的狗的血浆维生素C浓度，以评估其体内维生素C状态。血浆生化参数表明所有狗都存在肝脏异常。相比之下，这15只狗的血浆维生素C浓度在2.21至9.03毫克/升之间，只有2只狗低于参考范围（3.2至8.9毫克/升）。这些发现表明，患有PSS的狗的维生素C状态并未受损。
