The renal radiopharmaceutical preparations 99mTc-DMS and 99mTc-GH were examined chemically, biologically and clinically. Both preparations are of high radiochemical purity. The biodistribution of both preparations was examined in experimental animals at different time intervals, from 15 min to 4 hr; the percentage of incorporation of 99mTc-DMS into kidneys is much higher (29.4% to 52.0%) than that of 99mTc-GH (12.80% to 22.20%). Both preparations accumulate to a greater extent in the renal cortex than in the medulla.The most suitable time for renal scintigraphy for "mTc-DMS is 90-150 min while for 99mTc-GH it is 60-90 min. It is concluded that 99mTc-DMS is more suitable for static scintigrams on the scanner and 99mTc-GH for dynamic studies with the gamma camera.

This article is designed to carry out design of index system for evaluation of ecological city which is applicable to features of city of Ha’erbin on basis of actual conditions of Ha’erbin in principle of combination of qualitative analysis and quantitative analysis and to conduct evaluation on effect of restoration of ecological city of Ha’erbin with principal components analysis method. Results of evaluation show that some accomplishment has been made in terms of construction of ecological city of Ha’erbin and sub-system of environment, economy and society of Ha’erbin has been greatly improved since 2002.

AbstractTwo quantitative methods of analysing thyroid dynamic studies using 99mTc O-4 are compared for 33 patients (22 euthyroid, 8 hyperthyroid and 3 hypothyroid). A physiological model based on pertechnetate uptake by the thyroid is compared with principal components analysis. Both methods gave good separation between euthyroid and hvperthyroid in all but one case, while the separation between euthyroid and hypothyroid, although based on a small sample, appeared to be better for principal components analysis.
