The aim of the study was to demonstrate the possibility of transfemoral balloon occlusion of the coronary sinus and to detect changes of the left ventricular function during this occlusion in patients with angina pectoris. In 9 of 18 patients a stable occlusion over 15 seconds was performed. There were found only short term negative effects on the left ventricular contraction and relaxation. The coronary sinus pressure increased to 53 +/- 11 mm Hg. Numerous venous anastomoses made it difficult to occlude completely the sinus. The retrograde perfusion of the myocardium reached 20-30% of the antegrade one.

Two cases are reported: A young women of 18 with pseudo-achondroplasia and a 13 year old boy with hypochondroplasia. Similarities and differences between both diseases, achondroplasia and epiphyseal dysplasia are pointed out. It is likely, that the achondroplastic symptom complex and dysplastic processes of the epiphysis (in pseudo-achondroplasia under the spinal column) are no reason to regard these diseases as special forms of achondroplasia and epiphyseal dysplasia. They are independent diseases.

The urgent coronary surgery performed in patients with high risk unstable angina (rest pain greater than 48 h) shows still different results. We found in 57 urgent operated patients the same functional and clinical results as after elective bypass grafting. A higher in hospital mortality after urgent coronary surgery based on a higher number of grafts are occluded in the early postoperative period. The better prognosis concluded that the use of urgent coronary surgery is the therapy of choice in patients with refractory unstable angina pectoris.

In 143 persons professionally involved with the growing and processing of tobacco roentgenologic lung examinations were carried out. The detected diseases of the respiratory system were classified as exogenous allergic alveolitis (EAA), tobacco growers disease. The proven roentgenologic lung changes were grouped in roentgenologic symptom complexes, that correlate with the clinical variations of the disease (obstructive bronchitis, bronchial asthma, recurring pneumonia).

In 48 patients with rectal carcinoma diagnostic means for ultrasound investigation USU were tested. The high quality of transrectal and transvaginal ultrasound scanning (US) facilitated a detailed evaluation. The stage of the malign tumor was correctly evaluated in 95.8% of the cases. In one case a false negative evaluation of the function of the muscular layer was given and in another inflammatory infiltration was seen as a tumour. Changes of the pararectal lymph nodes were found in 62% of the patients, of the regional lymph nodes in 5 patients (10.3%). Their metastatic status was proven with fine needle puncture aspiration biopsy (FNPAB) under sonographic and lymphographic control. In 10 patients with US-scanning the found focuses in the liver parenchyma. In 90% of the cases by aspiration biopsy the malignity was cytologically and histologically proven.

With ultrasound the testicle sizes of 665 boys aged from 0 to 15 were measured. After computation of linear regression a nomogram of testicle growth in childhood was obtained. Besides testicle size the evaluation of intratesticular structure is another important information for the evaluation of maturity of testicles.

A basic improvement of the diagnostics of colorectal carcinoma (KK) in risk groups requires a complex program for a standardized fluorography of the colon and indication related endoscopy in ambulant treatment. For this we devised principles for the use of colon photofluorography as a screening method for the detection of colorectal carcinoma. In respect of organization this means the selection of risk groups and the use of new elements in colon photofluorography "prescopic period", that is carried out without radiation and automatic remote controlled air application into the rectum. We investigated 3120 patients in 96 cases and found one KK and 91 benign tumours. Our experiments show, that with this program the diagnostics of tumours can be significantly improved.

The results of roentgenpneumopolygraphy in 290 coal miners are analyzed. Localized diffuse ventilation disorders are detected, that are most pronounced in the upper and central lung regions. In all patients with dust bronchitis local and diffuse emphysematous ventilation disorder was detectable. In all patients with pneumoconiosis combined functional and morphologic changes were found. The use of x-ray function tests in coal miners facilitates an early detection of pathologic lung processes.
