[Therapeutic possibilities in the treatment of the myelodysplasia syndrome].

Myelodysplastic syndromes are clonal haemopoietic stem-cell disorders often associated with peripheral cytopenia due to the ineffective haemopoiesis and, there is a risk of transformation to overt acute leukaemia. Purpose of the therapy of various myelodysplastic syndromes is to reduce the severity of peripheral cytopenia with correction of ineffective haemopoiesis and, elimination of the aberrant haemopoietic clon. No standard treatment can be recommended for patients with myelodysplasia.

[Combined occurrence of renovascular hypertension, coarctation of the abdominal aorta, occlusion of the celiac and mesenteric arteries and kyphoscoliosis with neurofibromatosis--a case report].

The case is reported of a 16 year-old girl with arterial hypertension, generalized neurofibromatosis, coarctation of the abdominal aorta, bilateral renal artery stenosis, occlusion of the coeliac artery and superior mesenteric artery and kyphoscoliosis.

The effect of a protein-free diet on the renin-angiotensin system in the rat.

The effects of protein-free diet were studied in the rat. It was shown that the diet led to a decrease in total serum protein, in plasma renin activity, in plasma renin substrate and in blood pressure; and to an increase in haematocrit. A significant linear correlation was found in every combination between the total serum protein, plasma renin activity, plasma renin substrate and systolic blood pressure.
