[Erectile dysfunction: the current state of problem].

The article is dedicated to the physiological bases of erection, the pathophysiological mechanisms associated with erectile dysfunction, and detailed analysis of the reasons--psychological, neurological, endocrine, vascular reasons (arterial and related with dysfunction of the corpora cavernosa), leading to erectile dysfunction. The current aspects of diagnosis and treatment of patients with erectile dysfunction are discussed.

[Levitra in the treatment of patients with chronic prostatitis associated with sexual dysfunction].

Sixty patients with chronic prostatitis and sexual dysfunction were divided into two groups. All the patients received one-month standard course of physiotherapy. In addition, group I (n = 30) was given levitra (vardenafil; 5 mg per os each other day), the control group was not given this drug.

[Systemic approach to investigation of levitra efficacy in patients with chronic prostatitis with erectile dysfunction].

Ultrasonic dopplerography of prostatic, scrotal and penile vessels before and after intake of levitra in a dose 10 mg was made in 22 patients with chronic abacterial prostatitis in combination with erectile dysfunction and after their combined levitra treatment for a month taken each other day. It was found that levitra accelerates arterial inflow to the prostatic gland, testicles and penis (even in the absence of sexual stimulation and erection). This evidence indicates a distinct vasculogenic effect of levitra on male genitalia.

[The effect of ultra high frequency electromagnetic fields on the intrarenal blood flow and kidney morphology in pyelonephritis (experimental study].

The study was made of the action of electromagnetic decimetric waves (DMW) of mild and strong heat power and placebo on intraorganic circulation using functional polyrheography and morphological examination of the kidneys with infectious-inflammatory process. DMW of the above power have a marked hemodynamic action via stimulation of the circulation of the intermediary zone with an effect of redistribution of the intrarenal blood flow. Weak heat DMW in experimental pyelonephritis exhibit a distinct antiinflammatory effect while strong DMW impact aggravates vascular reaction associated with inflammation.

[Use of super-high frequency electromagnetic fields on intrarenal circulation and morphological status of health kidneys (experimental study)].

The experimental study investigated action of electromagnetic waves (84 mW/cm2 and 395 mW/cm2) on functional-morphological features of healthy kidney of female rats. A marked hemodynamic effect of decimetric waves is shown which operates via stimulation of intermediary zone with redistribution of intrarenal circulation. Disturbance of circulation occurs in dysregulation of the intrarenal blood flow under overstimulation of the organ circulation with 395 mW/cm2 decimetric waves.

[Study of the renal venous outflow using digital subtraction angiography].

A venous phase of digit subtraction angiography (DSA) of the kidneys was evaluated in 87 urologic patients. The subtraction allows satisfactory visualization of the renal veins. Amplification of the image and its early emergence indirectly suggest pathological arteriovenous shunt confirmed by intraoperative rheography.

[Renal adenomatosis against a background of hydronephrotic transformation].

A rare case of multiple (over 60) renal adenomas in a 24-year-old patient is described; the adenomas developed against the background of the hydronephrotic transformation resulting from the stenosis of the ureteropelvic segment.

[Juxtaglomerular apparatus and interstitial cells of the kidney medulla after the administration of certain drugs and use of hyperbaric oxygenation].

Electron microscopy was used to examine the status of the juxtaglomerular apparatus (JGA) and interstitial cells (IC) 3 and 24 hours after administration of furosemide (10 mg/kg), indomethacin (10 mg/kg), venoruton (500 mg/kg) and trental (100 mg/kg), and after 1,6 an 12 sessions of hyperbaric oxygenation. To evaluate objectively the results of examining the JGA, use was made of a method devised by the authors of a mathematical appraisal of granulation from the density of the epithelioid cells. Granulation of 50 IC from each animal was calculated on semi-thin araldite sections stained methylene blue-azur II-fuchsin.
