Laser Doppler: A Tool for Measuring Pancreatic Islet Microvascular Vasomotion In Vivo

Abstract:
Measurement of conduction velocity along the H reflex arc was used to study sensorimotor peripheral nerve function in diabetic patients during short- and long-term improvement of hyperglycemia. In ten type I diabetics a slight (p less than 0.05) conduction increase occurred after 6 hours of normal glycemia induced by an artificial endocrine pancreas. Similar but more prominent improvement occurred in twelve type I diabetics treated with continuous subcutaneous insulin injection for 6 months. The results suggest that nerve conduction slowing in diabetic patients stems partly from reversible, nonstructural abnormalities and partly from more slowly reversible morphological or chemical changes in peripheral nerve.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
