1. The possibility of artificial breeding Tree Shrew was explored.

2. A baby tree shrew, on the other hand, receives perhaps less maternal care than any other baby mammal.

3. Conclusion: The distributing charactristics of tree shrew forebrain cholinergic neurons were similar to those of rat and monkey.

4. Results:(1) The ciliary muscle of Tree Shrew is more like human's than mouse and rabbit.

5. Results indicate that the Chinese Tree Shrew can grow and breed normally in our experimental conditions.

6. The possibility of inducing estrus of Tree Shrew was explored using cloprostenol.

7. The very first mammals were small insectivores, probably very similar to this modern tree shrew.

8. The cytoarchitecture of the predominant reticular formation nuclei of the medulla oblongata in the tree shrew was studied with Nissl' s method.

9. The cytoarchitectonic organization of the cervical spinal cord of the tree shrew was studied with Nissl's stain method.

10. Results show that cloprostenol can be used to induce the estrus of Tree shrew and increase their reproductive rate effectively. 3) Methods for superovulation of Tree Shrew were investigated.

11. Objective:To investigate the possibility of using the spermatogonial cells as a vector to establish trans-gene animal model of tree shrew with HBV X gene.

12. Tree shrew (Tupain glis) in some references should be Northern tree shrew (T. belangeri).

13. FAGLU-induced histofluorescence method was used to determine locations of catecholamine-containing neurons (CA neurons) in the brain stem of Tree Shrew (Tupaia).

14. Just as many other mammals living in temperate zone, tree shrew belongesto photosensitive seasonally breeding-mammals.

15. The cytoarchitecture of the raphe nuclei of the brain stem in the tree shrew was studied with Nissl's method.

16. CONCLUSION: Social environment stress has significantly inhibitory effect on testosterone formation and destroy the testis structure of Chinese tree shrew.

17. The cytoarchltectonic organization of the thoracic spinal grey matter in the tree shrew was studied with Nissl's method.

18. The purification of UCP - l ( Uncoupling protein - 1 ) from BAT ( brown adipose tissue ) of the tree shrew.

19. In experiment(), the effect of YGAPM in treating rat's liver injury as well as HBV-infected tree shrew and duck HBV-infected ducks was observed.
