  • Nygotiska kyrkor i Skåne : utveckling i form, material och konstruktion 1840-1910
  • 1991
  • Book (pop. science, debate, etc.)abstract
    • Denna bok har sin utgångspunkt i 1981/82 års studier i skånskt 1800-talsbyggande där Arkitekturskolans restaureringslinje valde att ägna sitt intresse åt det relativt obeaktade bestånd av nygotiska kyrkor som Skåne erbjuder. Studiernas syfte har varit attförsöka fånga kyrkornas specifika såväl estetiska som tekniska karaktäristiska och beskriva den utveckling som de representerar.

  • Effects of low-dose X-irradiation on mouse-brain aggregation cultures
  • 1992
  • In: International Journal of Radiation Biology. - : Informa UK Limited. - 0955-3002 .- 1362-3095. ; 61:3, s. 355-363
  • Journal article (peer-reviewed)abstract
    • Biochemical and morphological differentiation in reaggregating mouse-brain cell cultures after low-dose radiation (0.5 Gy) in vitro was studied. Cells were irradiated on culture day 2, corresponding to embryonic day 15-16, and different glial and neuronal markers were followed through development to postnatal day 40. The shape and size of irradiated aggregates were more irregular and smaller compared with controls. Total amounts of DNA and protein were significantly lower in irradiated aggregates than in controls between days 8 and 20. After 30 days in culture activities of the glial markers glutamine synthetase (GS) and 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) were lower in X-irradiated aggregates than in controls. However, after 40 days the CNP activity in irradiated aggregates increased to levels above those of the controls. Irradiated and control aggregates did not differ significantly in neuronal marker enzyme activities, i.e. choline acetyltransferase (ChAT), acetylcholine esterase (AChE) and glutamic acid decarboxylase (GAD) measured on a per mg protein basis. On days 20 and 30 the amount of nerve growth factor (NGF) was two-fold higher in irradiated aggregates compared with non-irradiated ones, suggesting that, after irradiation, surviving cells in culture were induced to produce more NGF. After 40 days the amount of NGF in irradiated aggregates had decreased to the level found in the control aggregates.
