Results: Human stem cells were successfully transplanted into 6 fetal sheep and 5 lambs were born and lived. PCR analysis showed that there was human derived cell engraftment in the liver of the 5 lambs. Immunohistochemical staining and ISH with Alu probe showed human derived hepatocytes in the lobes or around periportal area, expressing albumin and CR18. Alu ISH also showed there were positive cells in the epithelia of bile duets.

In the research on the backward-wave oscillation suppression the startoscillation current which is derived from Two-wave theory approximately is given up. Four typical un-uniform slow wave structures start-oscillation current equations are derived by backward-wave amplifing gain expressions with the Two-wave theory. Then the start-oscillation current rates I〓/I〓 between ununiform circuit and uniform circuit of the four structures have been got.
