[Reflux nephropathy in children: early diagnosis and monitoring].

Vesicoureteral reflux (VUR) is the most common type of obstructive uropathy in children. Reflux nephropathy (RN) is one of the most common complications of VUR that inevitably leads to chronic kidney disease. Patients with end-stage kidney disease require costly treatment, and the only way to cure them is kidney transplantation. A timely institution of renoprotective therapy is a key factor helping to preserve the function of the native kidneys. Hence, it is necessary to devise new highly sensitive and minimally invasive methods for early diagnosis of RN. The purpose of this article is to review the molecular mechanisms of initiation and progression of kidney fibrosis and the opportunities of instrumental and non-instrumental methods for its diagnosis. Special attention is paid to highly specific and highly sensitive non-invasive methods for the detection of minimal changes in the renal parenchyma. The authors discuss the promising biomarkers for the diagnosis and prediction of RN.

[Influence of laser radiation of the whole blood in vitro on adhesion and aggregation of blood platelets].

The authors revealed dependence of reaction blood plates to photoeffect on the dose and rate of blood movement at laser radiation of donor blood in vitro. The red light decreases adhesion and aggregation of blood plates both at high and low rate of shift. Infrared laser radiation is effective only at high rate of shift leading to increase of adhesion and decrease of aggregation of blood plates. Blue laser is effective in small doses only and at low rate of sift it leads to decrease of adhesion and at high rate it provokes increase of adhesion. Blue laser do not have a significant influence on aggregation of blood plates. These results make possible to suppose ambiguity of biological response of venous and arterial blood to radiation.
