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 ... -
Immunohistochemical detection of p53 in non-malignant and malignant oral lesions associated with snuff dipping in the Sudan and Sweden
Ibrahim, Salah Osman; Johannessen, Anne Christine; Idris, Ali M.; Hirsch, Jan M.; Vasstrand, Endre N.; Magnusson, Bengt; Nilsen, Rune (Journal article, 1996)Immunohistochemistry was used to examine the expression of p53 in pre-malignant oral lesions and oral squamous-cell carcinomas (SCCs) from Swedish and Sudanese snuff-dippers, as well as in pre-malignant oral lesions and ... -
Mutations of the p53 gene in oral squamous-cell carcinomas from sudanese dippers of nitrosamine-rich toombak and non-snuff-dippers from the Sudan and Scandinavia
Ibrahim, Salah Osman; Vasstrand, Endre N.; Johannessen, Anne Christine; Idris, Ali M.; Magnusson, Bengt; Nilsen, Rune; Lillehaug, Johan (Journal article, 1999-11-08)Using PCR-SSCP/DNA sequencing methods, we analyzed 14 oral squamous-cell carcinomas (OSCCs) and 8 pre-malignant oral lesions from different Sudanese patients for prevalence of mutations in exons 5 to 9 of the p53 gene in ... -
The Swedish Snus and the Sudanese Toombak: are they different?
Idris, Ali M.; Ibrahim, Salah Osman; Vasstrand, Endre N.; Johannessen, Anne Christine; Lillehaug, Johan; Magnusson, Bengt; Wallström, M.; Hirsch, Jan M.; Nilsen, Rune (Journal article, 1998-11)In Sweden, snuff (locally known as snus), was introduced since the year 1637. Presently, Sweden has the highest per capita consumption and sale figures of snuff in the world, and the habit is becoming increasingly popular. ...
