मुटु,किड्नी,आखा,कान र फोक्सो समेत साटेर अरुको शरीरमा जोड्न बैज्ञानिकहरु त सफल भइसकेका छन् । बिज्ञानको अनौठो र अध्भुद चमत्कार झैँ पहिलोपल्ट एउटा शरीरको टाउको काटी अर्को शरीरसंग जोड्न सम्म सफल हुदै छन् बैज्ञानिकहरु । कसरी हुन्छ यस्तो शल्यक्रिया ? सानो जानकारी लिनुहोस् । भिडियो यो जानकारीको अन्त्यमा रहेको छ ।

There are three main technical challenges. As with any organ transplant, managing the immune response to avoid transplant rejection is necessary. Also, the brain is highly dependent on continuous flow of blood to provide oxygen and nutrients and remove waste products, with damage setting in quickly at normal temperatures when blood flow is cut off. Finally, managing the nervous systems in both the body and the head is essential, in several ways.

The autonomic nervous system controls essential functions like breathing and the heart beating and is governed largely by the brain stem; if the recipient body’s head is removed this can no longer function. Additionally each nerve coming out of the head via the spinal cord needs to be connected to the putatively corresponding nerve in the recipient body’s spinal cord in order for the brain to control movement and receive sensory information. Finally, the risk of systematic neuropathic pain is high and as of 2017 had largely been unaddressed in research.

Of these challenges, dealing with blood supply and transplant rejection have been addressed in the field of transplant medicine generally, making transplantation of several types of organs fairly routine; however as of 2017 in a field as common as liver transplantation around a quarter of organs are rejected within the first year and overall mortality is still much higher than the general population. The challenge of grafting the nervous system remained in early stages of research as of 2017.
