[新知] 頭部移植?
這是中國的研究, 在老鼠身上移植頭部. 移植完後有測試神經的反應. 但這比較特別的是
,為了維持腦部供氧, 他讓一顆心臟供應兩個腦的血液, 而每個腦只使用一條動脈與靜脈.
這是很詭異的研究阿, 移植頭部. 倫理問題想到就很複雜阿.

Mouse model of head transplantation is promising
(HealthDay)—The mouse model of allo-head and body reconstruction (AHBR) is
feasible for avoiding brain ischemia during transplantation, according to a
study published in the August issue of CNS Neuroscience & Therapeutics.
The mouse model of AHBR has been established to further the clinical
development of this strategy for patients who are suffering from mortal
bodily trauma or disease, yet whose mind remains healthy. With this in mind,
Xiao-Ping Ren, M.D., from The Second Affiliated Hospital of Harbin Medical
University in China, and colleagues examined the next steps through the model.
The researchers note that by establishing donor-to-recipient
cross-circulation by cannulating and anastomosing the carotid artery on one
side of the body and the jugular vein on the other side, the approach
retained adequate blood perfusion in the transplanted head. This strategy
preserved neurological function, as demonstrated by electroencephalogram and
intact cranial nerve reflexes.
"In conclusion, our short-term results with this model are inspiring," the
authors write. "The experimental method that we have described can allow for
long-term survival, and thus assessment of transplant rejection and central
nervous system recovery, bringing us one step closer to AHBR in man."
