The acute phase response follows tissue injury and contributes to its exacerbation with pro-inflammatory and pro-thrombotic mechanisms. Acute phase proteins promote erythrocyte aggregation and falling, with the result that the erythrocyte sedimentation rate (ESR) is a measure of the acute phase response. As the acute phase response accompanies ischaemic brain damage, we studied ESR values in patients within the first 24 hours of ischaemic stroke and evaluated whether these values may be related to the volume of anatomically relevant single hemispheric brain computed tomography (CT) areas observed at the same period, indicating early stroke-related cerebral changes. We observed an increase in ESR in stroke patients and a positive correlation between the ESR values and the volume of early brain CT hypodense areas. The results suggest that elevation in ESR values is observed soon after a stroke and may reflect the relationship between the degree of acute phase response in the early phase of ischaemic stroke and the extent of local brain damage.

Pinus sylvestris L. seedlings grown for 12-17 months in pure culture after inoculation with S and P strains of Heterobasidion annosum (Fr.) Bref. were studied with the help of light and transmission electron microscopy. Standardized inoculation procedure and uniform in vitro conditions allowed evaluation of the host/pathogen interactions. Necrotic reaction of the bark cells associated with the accumulation of dark-stained material in vacuoles, and lignification of their walls in root regions in proximity to mycelium were the common host reaction. Hypertrophy of the bark cells in areas invaded by hyphae caused a tension that was responsible for strong deformation of the bark cells. Injury to the vascular cambium resulted in formation of barrier zone parenchyma and abnormal xylem elements. High amount of polyphenolic material accumulated in new formed parenchyma cells was an effective chemical “barrier” to the centripetal spread of hyphae. Resin-plugged tracheids and row parenchyma cells rich in polyphenolic material were common in wood areas colonized by the fungus.
