The scientific objectives was to quantify the vascular changes in the brain, eye fundus, renal parenchyma, and splanchnic network. Heart, portal, jugular, femoral veins were investigate by Echography. The cerebral mesenteric, renal and ophthalmic arteries were investigated by Doppler. Eye fundus vein an papilla were investigated by optical video eye fundus.(More)
The main transplantation strategy in Parkinson's disease has been to place dopaminergic grafts not in their ontogenic site, the substantia nigra, but in their target area, the striatum with contrasting results. Here we have used green fluorescent protein transgenic mouse embryos as donors of ventral mesencephalic cells for transplantation into the(More)
As human will stay for long duration in isolated sites like ISS there will be a need to perform quick and reliable diagnosis to evaluate the gravity of the pathology in presence of clinical symptoms. Many pathological situations (abnormal heart rate, pericardic collection, mitral prolaps, cholecystis, renal lithiasis, normal and ectopic pregnancies, ovarian(More)
We assessed the use of air as a sonographic contrast agent in the investigation of tubal patency by sonohysterography. We examined 115 women assessed for infertility. After saline sonohysterography, small amounts of air were insufflated, and the tubal passage of bubbles was monitored. In five patients (excluded from the results), cervical stenosis prevented(More)
UNLABELLED Check if the stimulation of the leg muscles and neuro-sensorial system during stand test influence the cardiovascular response to stand test pre and post a 7 d HDT (4 subjects). METHODS After 20 min supine, the subject stood for 10 min, and closed the eyes for 1 min. Then he stayed 2 min stand up on ant-posterior or lateral unstable platform(More)
OBJECTIVE To evaluate the cardiac, arterial and venous effect of a venotonic drug (Cirkan "Ck") administrated orally daily to 6 subjects in HDT position during 5 days. These subjects underwent a second 5d HDT without Ck treatment one month later. Pre and post HDT the subjects were submitted to a stand test. METHOD The cardiovascular parameters were(More)
