A micromethod to measure ammonia.

Abstract:

:We have described a simple technique for the measurement of picomoles or nanomoles of ammonium. Samples can be easily processed on the day of an experiment. analysis of 14C-glutamate can be done at a later date by an accurate sensitive and reliable method. We can readily process 50 samples per day. The sensitivity can be increased by using smaller volumes of ammonia-free solutions, prereacting endogenous ammonia with nonradioactive 2-oxoglutarate, and increasing the specific activity of 2-oxoglutarate. The volumes must, however, be very low so as not to diminish the ammonium concentration and thereby limit glutamate formation.

  • The role of hyperparathyroidism, erythropoietin therapy, and CMV infection in the failure of arteriovenous fistula in hemodialysis.

    abstract:BACKGROUND:Vascular access failure is the main cause of morbidity in hemodialysis. Venous stenosis and subsequent thrombosis, as the result of intimal hyperplasia, is the major cause of vascular access failure. Intimal hyperplasia of the arteriovenous fistula (AVF) closely resembles the main histopathologic feature of ...
