About: Reid index

An Entity of Type: person, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Reid Index is a mathematical relationship that exists in a human bronchus section observed under the microscope. It is defined as ratio between the thickness of the submucosal mucus secreting glands and the thickness between the epithelium and cartilage that covers the bronchi. The Reid index is not of diagnostic use in vivo since it requires a dissection of the airway tube, but it has value in post mortem evaluations and for research.

Property Value
dbo:abstract
  • En fisiología, el índice de Reid es un cociente matemático que relaciona el espesor de la pared traqueo-bronquial del pulmón con las glándulas submucosas productoras de moco, localizadas en el punto de inspección. Al dividir el grosor de la pared del túbulo en cuestión entre el grosor de las glándulas, el índice normal es menor de 0.4, haciendo la contribución anatómica de la glándula serosa menor que el espesor del tubulo.​ En ciertas patologías del pulmón, como la bronquitis, la hipertrofia de las glándulas serosas hace que el índice de Reid aumente por encima de 0.4, haciéndose aún mayor con el progreso y empeoramiento crónico de la enfermedad.​ (es)
  • The Reid Index is a mathematical relationship that exists in a human bronchus section observed under the microscope. It is defined as ratio between the thickness of the submucosal mucus secreting glands and the thickness between the epithelium and cartilage that covers the bronchi. The Reid index is not of diagnostic use in vivo since it requires a dissection of the airway tube, but it has value in post mortem evaluations and for research. The Reid Index was developed in the late 1950s from the work of Dr. Lynne McArthur Reid, M.D. who first described the relationship between hypertrophic bronchial mucous glands and the resultant narrowing of the airways seen in chronic bronchitis. In 1967, Dr. Reid became the first woman to achieve the rank of professor of experimental pathology in England and later became the first dean of the Cardiothoracic Institute at London University.

  • In pneumologia si intende per indice di Reid il rapporto tra lo spessore dello strato ghiandolare sottomucoso e la parete bronchiale. Nei soggetti normali oscilla tra 0,14 e 0,36; negli affetti da BPCO ha un valore superiore a 0,44. (it)
