Background: Some variations of the cerebral arterial circle (CAC) are associated with an increased risk for the development of various pathological conditions. This paper aimed to determine the prevalence of hypoplastic arteries of CAC and to emphasize the limited possibility of their visualization by computed tomography angiography (CTA).
Materials And Methods: The research was performed on 400 adult cadavers by macro- and microdissection of the cerebral arteries.
Background: A variable artery in the anterior cerebral circulation, named median callosal artery (MdCA) belongs to one of the three groups of anteromedial central branches of the anterior communicating artery (ACoA). The lack of information on MdCA in human fetuses inspired the authors to explore and present its morphological features.
Methods: The arteries of the brain base were analyzed and measured on 193 specimens of human fetuses, whose values are preserved from the time of preparation of PhD thesis.
Purpose: Our goal was to investigate the cases of bilateral aplasia of the anterior cerebral artery (ACA).
Methods: The macro- and microdissection of the target human brain arteries of 388 cadaveric cases was applied under the magnifying glass. Each case was photographed and diagrammatically represented in the workbook.

Objective: Fatal reactions to the combination of ketamine-medetomidine and thiopental in Wistar rats are described in two different models of orthodontic tooth movement.
Materials And Methods: Thirty male rats were divided into two groups that required repeated anaesthesia during a 42-day study period, once a week or more frequently depending on the experimental group. The combination of ketamine [50 mg/kg body weight (b.
