Therapy of ocular complications in ANCA+ associated vasculitis.

ANCA+ associated vasculitis (AAV) is a group of rare diseases with potentially vision-threatening complications. Ocular and orbital complications of these diseases are caused by vasculitis of the small vessels of the eye or by granulomatous mass formation. ANCA (anti-neutrophil cytoplasmic antibodies) represent a key component of pathophysiological pathways as well as a diagnostic marker.

Imatinib inhibits spontaneous rhythmic contractions of human uterus and intestine.

The interstitial cells of Cajal (ICC) in the digestive tract and ICC-like cells in extradigestive organs express the c-kit tyrosine-kinase receptor, and have been implicated as pacemakers of smooth muscle spontaneous activity. We used imatinib mesylate (Glivec) to investigate whether c-kit activity of Cajal-like cells in human myometrium is involved in spontaneous rhythmic contractions of human uterine smooth muscle, taking intestinal smooth muscle as a reference tissue. We show that imatinib concentration-dependently inhibited the myogenic contractions of human myometrium in the organ bath, while it significantly affected noradrenaline or K(+)-induced contractions only at concentrations exceeding 50 muM.

[Technics for exploring the optic nerve].

This issue propose an inventory of the methods of investigation which help for the diagnosis of the optic neuropathies. These investigation methods are shortly presented, and the situation in which there are usefull are presented. Some of these investigation are expensive and are not available in any ophthalmological hospitals.
