7. China bred the first transgene calf.
The Shanghai Institute of Medical Genetics successfully bred China's first test-tube transgene calf by means of its newly invented technology which had already produced a transgene sheep. The institute's specialists simultaneously discovered a new method of greatly raising the gene expression level, so that the proteins of pharmaceuticals contained in the milk of transgene animals could increase by more than 30 times. The test-tube transgene calf, named ¡°Taotao,¡± was born on February 19, 1999, weighing 38 kg. According to an examination, it carries in its body the genes of human protein transplanted by scientific research personnel of the institute.
8. China successfully launched its first earth resources satellite.
At 11:16 on October 14, 1999, China successfully launched into the expected orbit the ¡°Resource No. 1¡± earth resources remote sensing satellite jointly developed by China and Brazil, along with a small Brazilian auxiliary scientific applications satellite.
After it is put into use, the ¡°Resource No. 1¡± satellite will transmit remote-sensing image information about visible light, and multispectral, short-wavelength and thermal infrared waves to China, Brazil and other countries and regions capable of receiving the information.
9. China's scientists successfully cloned giant panda embryos.
The Institute of Zoology of the Chinese Academy of Sciences and the
Fuzhou Giant Panda Research Center jointly cloned a batch of early panda embryos for the first time in the world by means of transplanting panda cells into an enucleated rabbit ovum. This is a manifestation of the fact that China has once again ranked itself among the world's foremost nations in giant panda research.
10. China's research into and development of human blood substitutes has reached the internationally advanced level.
According to the ¡°March 1986 Program¡± of the Chinese government, research into and development of human blood substitutes was selected as a major project in the nation's biological endeavors. The Beijing Kaizheng Bioengineering Development Company did research into blood substitutes by using animal hemoglobin as stroma, opened up a technical route with independent intellectual property rights, successfully transformed animal hemoglobin into a safe and effective human blood substitute, and secured three key technical patents. Research in this field has reached the advanced level among similar international research efforts. Efforts are being made to apply the findings to commercial and industrial use.
