Blood flow measurement in the canine pancreas

The Journal of Surgical Research
J G StudleyL H Blumgart

Abstract

Blood flow in the anesthetized animal has been measured indirectly by plethysmography and directly with the stromuhr, venous outflow, and electromagnetic flow techniques. Tissue perfusion in the gland has been assessed qualitatively with thermocouples and quantitatively by isotope fractionation, the distribution of microspheres, hydrogen desaturation, and clearance of either 133Xe or 85Kr. The results of these investigations have been conflicting as there is a large variation in both flow and perfusion measurements, not only overall but also in the values reported by each technique (Table 1). Taking all methods into account flow measurements have been recorded from 9 to 63 (mean 29.8) ml/min, and 10 to 200 (mean 66.1) ml/min/100 g. The mean percentage of the cardiac output distributed to the pancreas is 1.28. Some of these differences are due to various drawbacks associated with each of the techniques; some are almost certainly due to variations in the surgical preparations, and others are undoubtedly caused by the complexity of the pancreatic circulation. Measurements of perfusion in different regions of the pancreas of individual dogs show no difference if all vessels are intact, but accessory vessel ligation affects perfusio...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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.
