Abstract:
The objective of this study was to evaluate a new method for the treatment of acute hyperammonemia with a helium-oxygen mixture (heliox). We conducted a prospective, randomized, controlled study of male Sprague-Dawley rats. Experimental hyperammonemia was induced by 7 days of a high-ammonia diet. Subsequently, the animals were randomly divided into two groups: the study group treated with heliox breathing for 24 hours and a control group breathing room air for 24 hours. A prospective, randomized, controlled laboratory animal study was conducted at an animal research facility. The baseline plasma ammonia level was 9.49 +/- 10.96 micromol/L. After 7 days of a high-ammonia diet, the plasma ammonia level rose to 31.53 +/- 8.86 micromol/L. There was a significant statistical difference between the plasma ammonia level following 24 hours of heliox therapy (23.14 +/- 13.97 micromol/L) and the ammonia level in the control group (42.31 +/- 24.25 micromol/L) (P < .05). Heliox breathing was found to be an efficient treatment modality for decreasing plasma ammonia levels in an animal model. Further studies are required to evaluate its potential application in the treatment of patients with hyperammonemia.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
