In old cemeteries in the Wielkopolska region, 1124 localities of Hedera helix (European ivy) were found. In 863 of the cemeteries, flowering specimens of this species were observed. The populations are clearly of anthropogenic origin. The large number of its localities proves that it was popular in cultivation. In the past it had a symbolic meaning.

The studies of the vascularization of the cerebrum in polar fox were performed on 80 cerebral hemispheres. It was found that the middle cerebral artery is the strongest vessel supplying blood to the cerebrum. The artery gets divided into ten permanent branches. Two olfactory arteries supply the region of the cerebrum located on the border between the old and the new cortex. The other eight get divided into three branches running towards the region of frontal lobe of the brain, two branches to the region of the parietal lobe and three temporal branches running in the temporal region, which supply blood only to the new cortex of the cerebrum. The frontal, parietal and temporal branches descended independently from the main trunk of the middle cerebral artery or formed a common trunk. Common trunks for respective groups of branches have been described as the rostral, dorsal and caudal middle cerebral artery. In 10% of the cases there occurred two independent branches of the middle cerebral artery from the rostral cerebral artery.
