Cellular reactions and mineralization in induced heterotopic bone formation in guinea pigs
Nilsen, Rune (Doctoral thesis, 1981) -
The composition of gingival inflammatory cell infiltrates in children studied by enzyme histochemistry
Alcoforado, Gil Alves Pessanha; Kristoffersen, Tore; Johannessen, Anne Christine; Nilsen, Rune (Journal article, 1990-07)Gingival biopsies were obtained from 23 children, aged 5-11 years (8.6 ± 1.8 years). Specimens were taken from areas of the gingiva adjacent to the teeth which were to be extracted because of caries or its sequelae and ... -
Electron microscopy of induced heterotopic bone formation in guinea pigs
Nilsen, Rune (Journal article, 1977)A high yield of osteoid and some mineralized bone was induced in the abdominal muscles following implantation of allogenic demineralised and lyophilized dentine. The following types of cells and reactions were found: A. ... -
Electronmicroscopic study of mineralization in induced heterotopic bone formation in guinea pigs
Nilsen, Rune (Journal article, 1980)Mineralization of heterotopic bone was studied in a bone induction model using allogenic demineralization dentin implanted in the abdominal wall of guinea pigs. There was a high yield of newly formed osteoid and bone as ... -
Enzyme histochemical studies of acid phosphatise isoenzymes in induced heterotopic bone formation in guinea pigs
Nilsen, Rune; Magnusson, Bengt (Journal article, 1981)A bone induction model was used to study the effect of different pretreatments and inhibitors added to the substrate of acid phosphatise. Two different acid phosphatises (AcP) were demonstrated. The AcP of matrix-producing ... -
Enzyme histochemical studies of induced heterotopic cartilage and bone formation in guinea pigs with special references to acid phosphatise. A light and enzyme electron microscopic study
Nilsen, Rune; Magnusson, Bengt (Journal article, 1981)Heterotopic bone and cartilage formation was studied in a bone induction model in abdominal muscles of guinea pigs using demineralized allogenic dentin as inductive material. The light microscopical study showed high ... -
Enzyme histochemistry of induced heterotopic bone formation in guinea pigs
Nilsen, Rune; Magnusson, Bengt (Journal article, 1979)In an experimental bone induction model in guinea-pigs, large amounts of heterotopic osteiod and bone were found after 21 days. A semiquantiative intrasectional analysis of oxidative and hydrolytic enzyme activities in the ... -
Expression of biomarkers (p53, transforming growth factor alpha, epidermal growth factor receptor, c-erbB-2/neu and the proliferative cell nuclear antigen) in oropharyngeal squamous cell carcinomas
Ibrahim, Salah Osman; Lillehaug, Johan; Johannessen, Anne Christine; Liavaag, P. G.; Nilsen, Rune; Vasstrand, Endre N. (Peer reviewed; Journal article, 1999)Using immunohistochemistry, expression of p53, transforming growth factor-alpha (TGF-α), epidermal growth factor receptor (EGFR), c-erbB-2/neu and proliferating cell nuclear antigen (PCNA) was examined in 26 fresh frozen ... -
In Situ Expression of Cytokines and Cellular Phenotypes in the Lungs of Mice with Slowly Progressive Primary Tuberculosis
Mustafa, Tehmina; Phyu, S.; Nilsen, Rune; Jonsson, Roland; Bjune, Gunnar Aksel (Peer reviewed; Journal article, 2000-06)The cellular phenotypes and the expression of cytokines were studied in the lungs of mice, using immunohistochemistry, during different phases of slowly progressive primary murine tuberculosis infection. During the first ... -
Microfilaments in cells associated with induced heterotpic bone formation in guinea pigs
Nilsen, Rune (Journal article, 1980)Sera from active chronic hepatitis were used to demonstrate actin microfilaments in cells of a bone-induced model. Demnineralized and freeze-dried allogenic dentine was implanted in the abdominal muscles of Guinea pigs. ... -
A Mouse Model for Slowly Progressive Primary Tuberculosis
Mustafa, Tehmina; Phyu, S.; Nilsen, Rune; Jonsson, Roland; Bjune, Gunnar Aksel (Journal article, 1999-08)The progression from primary Mycobacterium tuberculosis infection to disease is usually slow in humans. The aim of this study was to develop and characterize a mouse model for slowly progressive primary tuberculosis, using ... -
X-ray microanalytical studies of initial mineralization in induced heterotopic bone formation in guinea pigs
Johannessen, Anne Christine; Nilsen, Rune; Bang, Gisle (Journal article, 1981)Allogenic demineralized dentin implanted in the abdominal wall of guinea pigs induced heterotopic osteoid and bone formation. Samples of this tissue were frozen at -140° C, freeze-dried at -80° C, infiltrated with Spurr® ...
