Classification and measurement of surface microvessels in man.

摘要: Abstract Capillary length, width, and number of loops per field have been measured in human surface microvessels. The nailfold was selected as a testing place because its easy accessibility, the possibility to photograph all their functional parts, comparative persistency capillary patterns. method measurement is described limitations discussed. Subjects included for study were 37 individuals without clinical disease, 20 patients with systemic lupus erythematosus (SLE), 25 progressive sclerosis (PSS). diagnoses had established independently by Rheumatic Disease Study Group at New York University School Medicine. percentage distribution types found each group is: normals, 71% within normal limits, 25% tortuous, 2% meandering, general enlargement, no giant loops; SLE, 21% 44% 32% 3% PSS, 23% 37% 6% 14% 20% giant. Measurements verified preliminary findings an earlier study, i.e., transitional limb width greater capillaries smaller PSS than normals SLE. usefulness this approach discussed terms possible significance findings.
