The efficacy and tolerability of a fixed combination of 160 mg sabal fruit extract WS 1473 and 120 mg urtica root extract WS 1031 per capsule (PRO 160/120) was investigated in elderly, male patients suffering from lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia in a prospective multicenter trial. A total of 257 patients (129 and(More)
PURPOSE To study the effects of noninvasive transcranial focal electrical stimulation (TFS) via tripolar concentric ring electrodes (TCRE) on the electrographic and behavioral activity from pentylenetetrazole (PTZ)-induced seizures in rats. METHODS The TCREs were attached to the rat scalp. PTZ was administered and, after the first myoclonic jerk was(More)
Presented herein is a clinical case report regarding a patient who was found to have embolism of the right renal artery with accompanying atrial fibrillation. Open surgery is viewed as a method of choice amongst a variety of the available treatment modalities aimed at re-establishing renal blood supply impaired due to embolism of the renal artery trunk.(More)
The article presents an experience with application of tension-free plasty of the anterior abdominal wall using reticular endoprostheses. New endoprostheses of Reperen are developed and applied, a method of sutureless fixation of polypropylene net in the abdominal wall tissues is proposed when performing plasty for great ventral hernias. Advantages of new(More)
The paper reports on 127 operations on the open heart for mitral incompetence, including 112 prostheses and 15 annuloplasties on the support ring. After operation 28 (22.0%) patients died. Among the operated on patients with stage II-A circulatory insufficiency mortality was 9.3%, in those with stage II-B it was 28.5%. Mortality with mitral valve prosthesis(More)
The Cleveland Clinic Implantable Ventricular Assist System (IVAS) is a nonpulsatile rotary pump designed to augment the failing left ventricle. The purpose of this study is to assess its impact on the cardiovascular system using computer simulation. The authors modified an existing numerical model (24 coupled differential equations representing all cardiac(More)
We operated on a total of twenty-seven patients presenting with acute massive thromboembolism of pulmonary arteries. The patients' mean age amounted to 38.6 ± 9.17 years. The estimated pressure in the pulmonary artery averaged 54.2 ± 7.15 mm Hg. A total of twenty- two thromboembolectomic procedures were performed in the setting of assisted circulation. In(More)
Operations were fulfilled on 42 patients with embolism threatening formations of the right parts of the heart. An episode of pulmonary arteries was in the anamnesis of 11 patients. In all cases the operations were fulfilled under conditions of extracorporeal circulation and cardioplegia. One patient died at the hospital. Lethality was 2.33%.
The article presents indications to surgical correction of aortal stenosis and its variants in patients with rheumatic diseases combined with a lesion of other valves of the heart. The possibility to fulfill valve-saving plastic operations on the stenosed aortal valve was shown in 110 operations. The results obtained proved advantages of plastic operations(More)
