Synthesis of protein amides from ammonia has been proposed (Bliss (1)) as a tissue function whose demonstration is of cardinal importance to the development of the theory that blood protein amide nitrogen represents detoxified ammonia, first employed in tissues for neutralization of acid, in course of transport to the kidneys where the amide nitrogen reappears as urinary ammonia. Questionable i...

In the method here presented Nash and Benedict’s (1921) procedure for aerating the ammonia from blood into an acid-receiving solution is utilized without modification. For determining the ammonia obtained, however, we have employed, instead of Nesslerization, the blue color developed when ammonia is heated with an alkaline solution of phenol and hypochlorite. This reaction was apparently first ...

The objective of this study was to investigate the effect of a partial substitution of soybean meal with field pea (Pisum sativum) in Holstein lactating dairy cow diets on dry matter intake, milk yield and composition, blood metabolites, rumen ammonia-N concentration and pH. Eighteen lactating Holstein cows were randomly assigned into three groups based on parity, days in milk, and mil...

BACKGROUND Ammonia is a critical factor in the pathogenesis of minimal hepatic encephalopathy (MHE). Most of the ammonia is from bacterial production in the intestinal tract. Non-absorbable antibiotics and non-absorbable disaccharides are therefore the therapy of choice. A few studies have addressed the effect of ammonia produced by H. pylori in the pathogenesis of MHE. METHODS In this prospe...

Juvenile Anoplopoma fimbria (mean length 16.8 ± 2.2 cm, and mean weight 72.8 ± 5.4 g) were exposed for 2 months with different levels of ammonia (0, 0.25, 0.50, 0.75, 1.00, and 1.25 mg/L). Growth performances such as daily length gain, daily weight gain, condition factor, and hepatosomatic index were significantly decreased by ammonia exposure. Hematological parameters such as red blood cell (R...
