Fluid secretion in the duodenum and intestinal handling of water and electrolytes in Zollinger-Ellison syndrome

Abstract

The slow marker perfusion technique was used in five patients with the Zollinger-Ellison syndrome in order to determine the basal and postcibal flow rates of fluids passing the duodenojejunal junction and distal ileum, and the composition of those fluids. Fecal water and electrolyte excretions were also measured. The 24-hr outputs at the ligament of Treitz were markedly increased, while fecal losses were normal or only slightly increased. Thus, the overall intestinal reabsorption of water was 96%. Fasting rates of fluid and electrolyte flow at the ligament of Treitz were also measured during a basal period, followed by a period of continuous gastric aspiration. Removal of gastric secretion had the following effects on the fluid passing through the duodenum: (1) dramatic decrease in flow rate; (2) an increase in osmolality, from hypotonicity to isotonicity; (3) rise of pH, from acid to alkaline values; (4) a decrease of PCO2, from high to normal values. No increase in fasting plasma levels of immunoreactive secretin and motilin was observed in Zollinger-Ellison syndrome, whereas normal subjects respond to acid in the duodenum by a marked rise in the circulating levels of these hormones. These facts suggest that, in Zollinger-Ell...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
