[Nuclear stethoscopy. The clinical technic, methods and applications]. / Stetoscopia nucleara. Tehnica, metoda si aplicatii clinice.

The paper reports on a new way of cardiological, radionuclidic investigation of the patients, a technique used for the first time in Romania. The technique and investigation method are presented in detail, with emphasis on some more important stages. As resulting from the description of the methodology, the performances of the left ventricle consist of three types of radioactivity/time curves at: first passage, beat by beat, and their summation. Of the advantages offered by the nuclear stethoscope, mention should be made that, besides the evaluation of systolic and diastolic parameters, it monitors the left ventricle functions in the rhythm disturbances, beat by beat, and being mobile, it permits the investigation at the patient's bed. Finally, the paper presents several cases investigated by the authors, and their special clinical applicability.

New possibilities in colour echotomography (computer-aided colour echotomography).

The present work discusses the technical bases and clinical significance of colour echography. Connecting the echograph to a high capacity computer through a Videotron permits the processing of colour images with the help of clinical programmes. This increases the accuracy of the diagnosis, and broadens the sphere of application of echography.

[Urinary carcinoembryonic antigen in patients with urothelial tumors. Correlations with the stage of the disease and the modal chromosome number]. / Antigenul carcinoembrionar urinar la bolnavii cu tumori uroteliale. Corelatii cu stadiul bolii si numarul cromozomial modal.

The carcino-embrionary antigen was estimated in 26 patients without malignant diseases (15 with inguinal hernia and 11 with urinary lithiasis--all of them before surgery), and in 47 patients with urothelial tumors. The direct radioimmune technique was used (a commercial kit from France /CEA IRE SORIN/) applied to isolated samples of sterile urine obtained at 12 hours. It was noted that:--patients without urologic disturbances had values under 1.5 micrograms in 12 hours in 93.4% of the cases;--in 44% of patients with non-malignant urological diseases (urinary lithiasis) the antigen values ranged between 1.5 and 3.0 micrograms in 12 hours;--patients with urothelial tumors had high values of the urinary carcinoembrionary antigen, in the range between 1.92 and 162.5 micrograms;--concentration of the urinary carcino-embionary antigen increases with the stage of the disease, with tumor polyploidia and in tumors with a high degree of anaplasia;--10--14 days after the removal of the tumor the values of the carcino-embrionary antigen show a significant decrease, even after total cystectomy but with cutaneous uretherostomy.
