Avaliação histoquímica quantitativa do colágeno na fascia transversalis e na bainha anterior do músculo reto abdominal em doentes com hérnia inguinal

Abstract: OBJETIVO: Avaliar a participação do colágeno na etiopatogenia das hérnias inguinais, através da análise quantitativa histoquímica do colágeno na bainha anterior do músculo reto abdominal e na fascia transversalis MÉTODO: Foram operados quarenta doentes do sexo masculino, na faixa etária entre 20 e 60 anos, portadores de hérnia inguinal tipo II e IIIA de Nyhus e realizadas autópsias em dez cadáveres frescos, na mesma faixa etária. Em ambos os grupos, amostras da bainha anterior do músculo reto abdominal e da fa… Show more

“…They showed that the average percentage area of collagen in patients with hernia was half the area of the controls 20 . A similar study conducted by the authors of this study showed no statistically significant differences between patients with direct hernia, indirect one and controls without hernia 21 .…”

“…The images were captured using the software LAS® Leica Application Suite. Eight fields per slide of each rat of both groups were analyzed at 400x magnification (four fields from epidermis‐upper dermis and four fields of the lower dermis‐hypodermis) for inflammatory infiltrate and fibroplasia quantification . Images of fields at 100x magnification in the epidermis‐dermis‐hypodermis direction were evaluated for angiogenesis quantification.…”

“…Next, specimens embedded in paraffin were cut into 4-μm sections using a microtome. The histological sections were mounted onto slides and stained with hematoxylin and eosin (H&E) and special stains for collagen, including picrosirius red, Masson's trichrome, and reticulin, and immunostained with antibodies for collagen types I, II, III, IV, and V.FIGURE -Sites from which fragments of the rectus abdominis muscle were collected for analysis.Hematoxylin and eosin stainingRoutine histological staining with H&E was performed.The histological sections were deparaffinized in xylene, rehydrated through a graded series of ethanol, and washed in running water.The sections were then immersed in Harris' hematoxylin for two minutes, washed in running water (five minutes), rinsed in distilled water (one minute), stained in an aqueous solution of eosin (five minutes), and dehydrated in ascending concentrations of ethanol.Next, the sections were cleared in xylene (three successive changes, one minute each) and mounted under a cover-slip in Entellan14 . The histological sections were stained with H&E for the detection of technical artifacts and histopathological changes(Figure 2).…”
