[A centering guide for the gamma camera].

A device for centering a gamma-camera indicator is described. It permits the use of available medical coaches instead of a table with a transparent top. The device can be used for centering an indicator (when it is fixed at the low end of a gamma-camera) on a required area of the patient's body.

[Evaluation of the photon correlation method of measuring skin blood flow and its use in the diagnosis of microcirculation disorders in patients with diabetes mellitus].

A new photon-correlation method for measuring blood flow and traditional methods for blood flow measurements according to the clearance of 133Xe were studied and compared. The measurement data of the skin circulation by the photon-correlation method and according to the clearance of 133Xe are in linear relationship, the correlation ratio being equal to +0.93 (P less than 0.01). At the same time the photon-correlation method has some advantages. Particularly it is marked by non-invasiveness, high accuracy, good reproducibility of the data and short exposure time. Photon-correlation spectroscopy was used to perform clinical studies of the skin circulation in different anatomic areas of the skin in diabetes mellitus patients. Altogether 117 subjects aged 19-60 years were examined. There were 38 healthy subjects and 79 patients with diabetes mellitus. The skin circulation was measured from the finger tip and from the internal surface of the upper third of the forearm. In healthy subjects, the skin circulation appeared substantially higher in the finger tip than in the forearm. In diabetes mellitus patients, the circulation in the finger skin was also higher than in the skin of the forearm. As compared to healthy subjects, the patients manifested a significant lowering in the finger circulation and only the tendency towards its decrease in the forearm.

[Integral index of the rate of blood clearance of labelled hippuran].

Significant correlation between the values of the effective renal blood flow (RBF) and indices calculated on a curve of "blood" radioactivity was established. Based on a comparison between RBF values and indirect indices some equations were obtained characterizing mathematical dependence between them. A conclusion has been made that the integral index of blood clearance of labeled hippuran calculated by indirect indices, is more accurate and can be used in routine studies.

[Assessment of the passage of urine in the upper urinary tract based on radionuclide renographic data].

A group of 516 patients was studied using the routine renographic method. It can be admitted that 3 min after registration of maximum radioactivity in the kidney the curve of the radionephrogram in the interval of 7 min and that of radioactivity in the cardiac area within the same time interval are similar. Proceeding from this supposition coefficients of intensity of hippuran comparative outflow from the kidneys (K), from the kidney and blood (D) have been proposed. Using K and D coefficients the criteria of an extent of urinary passage delay from the upper urinary tract were determined. It has been established that renal function increases with age; therefore, age should be taken into consideration while assessing renographic results. In nephroptosis due to kidney forward shift the renal function index is to be understated. Renography has been shown advantageous in the evaluation of urine function and passage before chromocystoscopy in cancer patients.
