Masson trichrome

Figure 1. Masson trichrome stainings of lung (xlOO) 3 h (A), 24 h (B), 3 days (C) and 10 days (D).

Histological section (Masson trichrome) of nonresorbable 100% polybutylene terephthalate (PBT) fibers after 126 days in a subcutaneous rat model showing the extent and distribution of collagen matrix production around bundles of fibers. 

Representative sections (6 pm) of each organ were stained with Masson s trichrome and hematoxylin/eosin.

Fig. 5. Histopathological characteristics of left ventricular specimens taken from mice overexpressing the human P,-AR. The upper panels show (A) H E stain, (B) Masson s Trichrome stain, and (C) signal for epitope-tagged human P,-AR protein in control hearts. The lower panels (D-F) show representative sections from transgenic mice overexpressing the human P,-AR. (See Color Plate 4 following p. 148 from ref. 95, 2000, with permission from Elsevier.)...

FIGURE 20.4 This specimen from a brain abscess shows an infiam-matory iesion with a distinctive waii of coiiagen-stained cyan with Masson s trichrome stain. Brain around this waii (orange side) contains highiy reactive (gemistocytic) astrocytes. Toward the center of the abscess (gray side) are ieukocytes and swoiien macrophages. 

Fig. 5. Sagittal section showing ir-LHRH tracts (arrows) extending from the NOR (N) along the ventral margin of the olfactory bulb (OL). Section has been counterstained with Masson s trichrome. Anterior is the right. Bar, 50 micra. (From Schreibman et al., 1984.)... 

Fig. 5. A photomicrograph of a twenty-eight-week old fetal mandible, showing the symphyseal secondary cartilage. Notice the centrifugal ossification in the secondary cartilage, b = bone c = cartilage m = symphyseal mesenchymal tissue. (Masson s trichrome X 200).

Fig. 8. A photomicrograph in the caudal portion of a forty-week old fetal mandible, showing the mesenchymal tissue (m). A mental ossicle (mo) is present in the caudal portion of the mesenchyme, me = remains of Meckel s cartilage b = bone of the hemimandible. (Masson s trichrome x 100).

All colonic biopsies showed erosions with severe infiltration by inflammatory cells. Masson s trichrome staining identified subepithelial collagen bands as thick as 25 pm in every specimen, consistent with collagenous colitis. Lansoprazole was withdrawn, and within a few days the watery diarrhea disappeared. Colonoscopy 2 months later showed a reduction in the number of red spots. Biopsies from the cecum, ascending, transverse, and descending colons, and rectum, showed no collagen bands. 

Iron overload following dietary administration of dicyclopentadienyl iron (ferrocene) becomes primarily evident in hepatocytes with only a small amount present in Kupffer cells (Valerio and Petersen 2000). A striking pattern of iron deposition occurred in ferrocene-fed mice as evidenced by large circular deposits of haemosiderin in the cen-trilobular hepatocytes. Masson s trichrome stain revealed a mild increase in fiver collagen associated with iron-loaded centrilobular hepatocytes. Hy-droxyproline was significantly (P < 0.05) increased. Malondialdehyde concentrations as a marker of lipid peroxidation were increased fourfold (P < 0.05). 

Masson s trichrome staining, as well as TEM observation. In this chapter, a systematic investigation and comparison of nerve repair is made using scaffolds made from PUCL-fl/t-PEG, PUCL-ran-PEG, autograft, PCL, silicone tube, and negative control in an SD rat model.
