1. Objective: Using Nuclein Ventriculography technique to evaluate the effect of Chronic Renal Insufficiency (CRI) on the left ventricular function.

2. Objective:To determine the effect of nuclein 32 P colloid in treatment of chronic maxillary sinusitis(CMS).

3. Methods Color Doppler ultrasound and nuclein scanning in 34 patients with thyroid nodules was retrospectively analysed.

4. Conclusions Both color Doppler ultrasound and nuclein scanning were effective and painless in the diagnosis of the thyroid nodule and each has its own superiority.

5. The common pathogeny, clinical manifestation, nuclein lung scanning and some examination methods were emphatically analyzed. Further more, kinds of treatments and effects were compared.

6. Objective: To evaluate clinical application of treatment for intractable pain of compression fracture of osteoporosis with nuclein 89Sr.

7. Conclusion: It is a safe and effective method to treat the intractable pain of compression fracture of osteoporosis with nuclein 89Sr.

8. The distribution law and comparison of heavy metal Cu and radioactive nuclein 3H in different tissues and organs of crucian are carried out.

9. Results Some symptoms, like dyspnea in 7 cases disappeared. Some signs, like hepatauxe in 6 cases were obviously improved. The index of blood gas and nuclein lung scanning in 6 cases return to normal.
