[Analysis of the volume of the cerebral circle and basal artery in the blue fox].

Observations were performed on 30 brains of blue foxes, whose arteries were filled with synthetic latex. The measurements of volume, length and diameter of the basal artery and arteries that made cerebral circle were done using digital image analysis system. It has been indicated that an average volume of the cerebral circle in that species was 12.96 mm3 and was statistically highly important correlated with the weight of the brain (0.83). The total volume of the cerebral nasal arteries was estimated as 4.96 mm3 and the volume of the communicating caudal arteries was 8.08 mm3. No statistically important correlation has been indicated between the weight of brain and the volume of the basal artery (8.84 mm3). The volume of the basal artery was negatively correlated with the length of the vessel (-0.42).
