[Age-related changes in the level of serum bone markers in healthy children].

Age-related changes in the blood level of bone metabolic markers were compared in healthy children living in different geographical regions. The absolute value of carboxy-terminal telopeptide of type 1 collagen type 1 (beta-CrossLaps) and that of total procollagen type 1 amino-terminal propeptide (PINP) were found to depend on living conditions and the nature of changes in the serum markers of bone metabolism was related to the processes of natural growth and development in children. A child's individual growth curve can be used to identify target groups for the prevention of osteopenia.

[Renal dysfunction and mitral regurgitation in patients with chronic heart failure].

The objective of this study was to elucidate the relationship between mitral regurgitation (MR) and the glomerular filtration rate (GFR) in patients with chronic heart failure (CHF). A total of 340 patients with CHF (200 men and 140 women, mean age 58.0 +/- 12.

[Impact of day-to-day arterial pressure variability on the left ventricle geometry in patients with predialysis chronic kidney insufficiency].

Aim: To estimate the impact of day-to-day variability of blood pressure (BP) on left ventricular geometry in pre-dialysis patients.

Material And Methods: We estimate the impact of day-to-day variability of BP on left ventricular geometry in 42 non-diabetic pre-dialysis patients (22 F, 20 M, mean age 47 +/- 12 years) with arterial hypertension (> 140 and 90 mm Hg). Serum creatinine was 286.

[Effects of arterial compliance on geometry of the left ventricle in patients with pre-dialysis chronic renal failure].

To examine relationships between left ventricular geometry and general arterial compliance (GAC) in patients with predialysis chronic renal failure (CRF). 102 patients with predialysis CRF unrelated to diabetes mellitus (males 46, females 56, mean age 49.1 +/- 18.

[Relations of acid-base balance and gastric secretion of hydrogen carbonate ions in patients with peptic ulcer].

Aim: To study acid-base balance (ABB) of the organism, gastric secretion of hydrocarbonate (HCO3-) in ulcer patients and to examine their relationships.

Material And Methods: ABB in capillary or venous blood before and after losec and famotidine treatment and gastric secretion of HCO3- were studied in 72 patients with ulcer.

Results: It was found that patients with gastroduodenal ulcer have metabolic, less frequently hypercapnic acidosis with suppressed gastric secretion of HCO3-.
