The main reason responsble to leukoaraiosis was ischemia in white matter leading to neuroglia degeneration and demyelination. Leukoaraiosis may cause or deteriorate disturbance of intelligence.
The diagnosis in this case was tumefactive demyelination, which may be thought of as a solitary demyelinating lesion measuring greater than 2 cm and with characteristics that mimic neoplasm.
The two metabolites of morphine, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G), are mainly formed by morphine glucuronidation in the liver.
The evoked responses have the specificities with higher threshold, longer latency, complex reactive patterns, and being inhibited by the action of morphine.
That led Dr Benedetti to wonder if the effect of legally administered pre-competition morphine might, perfectly legally, be carried over into a competition by giving a placebo.
The result showed: (1) In the same patient alone, the demyelination in the diseased nerve branch was even more serious than that in the undiseased one.
The hyperintense bands on T2 weighted images correspond to concentric bands of demyelination with gliosis and perivascular lymphocytic infiltration (5).
The myelin sheath of the sciatic nerve was characterized by edema of different degrees, vacuole-like denaturation, structural derangement and local demyelination.
The results also showed that degree of demyelination of branches of sciatic nerve were different and possibly associated with curled toe paralysis or no curled toe paralysis.
Those elements that allowed Borlaug's projects to succeed, such as well-organized economies and transportation and irrigation systems, were severely lacking throughout Africa.
