Moyamoya disease is a chronic non-inflammatory arteriopathy affecting vessels of the central nervous system, described rarely in non-Oriental populations.  We document this condition in a middle -aged African male with typical clinical and angiographic features and review the current literature.

Обзор посвящен многогранности дофаминергической системы. Дофамин синтезируются в центральной нервной системе и желудочно-кишечном тракте. В первой части обзора представлены современные данные литературы о роли дофамина в процессе старения. Обсуждаются также механизмы, лежащие в основе депресивного расстройства с точки зрения участия дофаминергической системы в плане объединения некоторых концепций: моноаминергической, воспалительной, эпигенетической, нейротрофинной и анти-апоптической. The review is devoted to multifunctional properties of dopaminergic system. Dopamine is synthesized in the central nervous system and gastrointestinal tract. The first part of the review presents the current literature data on the role of dopamine in the aging process. We also discuss the mechanisms underlying depressive disorder in terms of participation of the dopaminergic system to bring together some concepts: monoaminergic, inflammatory, epigenetic, neurotrophins and anti-apoptotic.

✓ Amyloidomas of the central nervous system are rare. Two cases involving middle-aged patients with neurological symptoms are presented. Massive focal accumulations of amyloid in the cerebral hemispheres were confirmed pathologically.

With the advent of the space age and the need to determine the requirements for a space cabin atmosphere, oxygen effects came into increased importance, even though these effects have been the subject of continuous research for many years. In fact, Priestly initiated oxygen research when in 1775 he published his results of isolating oxygen and described the effects of breathing it on himself and two mice, the only creatures to have had the “privilege” of breathing this “pure air”.Early studies had demonstrated the central nervous system effects at pressures above one atmosphere. Light microscopy revealed extensive damage to the lungs at one atmosphere. These changes which included perivascular and peribronchial edema, focal hemorrhage, rupture of the alveolar septa, and widespread edema, resulted in death of the animal in less than one week. The severity of the symptoms differed between species and was age dependent, with young animals being more resistant.

Studies using mesenteric and ear chamber preparations have shown that interendothelial junctions provide the route for neutrophil emigration during inflammation. The term emigration refers to the passage of white blood cells across the endothelium from the vascular lumen. Although the precise pathway of transendo- thelial emigration in the central nervous system (CNS) has not been resolved, the presence of different physiological and morphological (tight junctions) properties of CNS endothelium may dictate alternate emigration pathways.To study neutrophil emigration in the CNS, we induced meningitis in guinea pigs by intracisternal injection of E. coli bacteria.In this model, leptomeningeal inflammation is well developed by 3 hr. After 3 1/2 hr, animals were sacrificed by arterial perfusion with 3% phosphate buffered glutaraldehyde. Tissues from brain and spinal cord were post-fixed in 1% osmium tetroxide, dehydrated in alcohols and propylene oxide, and embedded in Epon. Thin serial sections were cut with diamond knives and examined in a Philips 300 electron microscope.

Acetylcholinesterase (EC 3.1.1.7) (ACHE) has been localized at cholinergic junctions both in the central nervous system and at the periphery and it functions in neurotransmission. ACHE was also found in other tissues without involvement in neurotransmission, but exhibiting the common property of transporting water and ions. This communication describes intracellular ACHE in mammalian bone marrow and its secretion into the extracellular medium.
