Pathophysiology. Rupture of the membranes is the most common cause of oligohydramnios. However, because the amniotic fluid is primarily fetal urine in the latter half of the pregnancy, the absence of fetal urine production or a blockage in the fetus' urinary tract can also result in oligohydramnios.
oligodendrocyte. Oligodendrocytes, also known as oligodendroglia, belong to a class of cells in the central nervous system known as glial cells. Oligodendrocytes are responsible for producing a fatty protein, called myelin, which insulates axons, the long extensions of nerve cells (neurons) . In acute MS lesions, typical of very aggressive disease courses, oligodendrocytes are found in large numbers and there is evidence of abortive remyelination-probably the new myelin is being destroyed faster than the oligodendrocytes can lay it down.
