[Topic] To design transplant materials with performance and quality more suitable for clinical medical use, a method for preparing transplantation model animals is provided, which enables a highly reliable and reproducible transplantation experimental system. [Solution] The evaluation method of the present invention for transplantation materials similar to autologous transplantation enables the preparation of transplantation model animals similar to autologous transplantation, which enables a highly reliable and reproducible transplantation experimental system, by including the following steps: applying a crude extract of a donor expressing a marker to a newborn recipient to obtain a recipient immune to the aforementioned donor; and transplanting transplantation material to the immune-tolerant recipient, wherein the transplantation material comprises an artificial transplantation material covered, adhered to, infiltrated, or contained in the tissue or cells of the donor expressing the marker.

The present article relates to an artificial graft (artificial blood vessel) used in surgical procedures such as bypass surgery (such as implantation of an artificial blood vessel).

The invention discloses a grafting propagation method for seedlings of endangered species trifoliate orange, and relates to the technical field of grafting propagation of trifoliate orange. Comprising the steps of grafting stock preparation, scion collection and treatment, grafting and management after grafting, and the efficient and stable grafting propagation method for the trifoliate orange is established. According to the grafting method, common trifoliate orange with high adaptability and stress resistance is adopted as the stock for grafting, the grafted trifoliate orange seedlings are high in survival rate and high in disease and pest resistance, and the stress resistance and adaptability of the trifoliate orange are improved. The technical problem that the survival rate of the trifoliate orange is low in the transplanting and returning process is effectively solved. The method has the advantages that the breeding survival rate of the trifoliate orange can be effectively kept, the problem that the fibrous roots of the trifoliate orange are few is solved, the transplanting survival rate is remarkably increased, and the breeding cost is low. The artificial grafting and seedling raising method for the trifoliate orange is established for the first time, and is of great significance to rescue protection of the trifoliate orange and reconstruction of field populations.

To provide a method for preparing a transplantation model animal which makes it possible to realize a highly reliable and highly reproducible transplantation experimental system, in order to design a transplantation material which ensures performance and quality that are more suitable to clinical medical care.SOLUTION: A method for evaluating a transplantation material which is similar to that in autoplastic transplantation comprises: a step of administering, to a recipient newborn, a crude extract from a labeled marker expression donor to obtain a recipient which is immune tolerant to the donor; and a step of transplanting, to the recipient which is immune tolerant, the transplantation material which includes an artificial graft material that tissue or cells of the labeled marker expression donor cover, adhere to, infiltrate, or include. Thus, the method allows preparation of a transplantation model animal which is similar to that in autoplastic transplantation and which makes it possible to realize a highly reliable and highly reproducible transplantation experimental system.SELECTED DRAWING: Figure 1

[Problem] Provided is a method for preparing a transplantation model animal which makes it possible to realize a highly-reliable and highly-reproducible transplantation experimental system, in order to design a transplantation material which ensures performance and quality that are more suitable to clinical medical care. [Solution] This method for evaluating a transplantation material which is similar to that in autoplastic transplantation comprises: a step for administering, to a recipient newborn, a crude extract from a labeled marker expression donor to obtain a recipient which is immune tolerant to the donor; and a step for transplanting, to the recipient which is immune tolerant, the transplantation material which includes an artificial graft material that tissue or cells of the labeled marker expression donor cover, adhere to, infiltrate, or include. Thus, the method allows for preparation of a transplantation model animal which is similar to that in autoplastic transplantation and which makes it possible to realize a highly-reliable and highly-reproducible transplantation experimental system.

The invention relates to a device designed to ensure the continuity of blood flow by enabling the connection of the aorta and an artificial graft using a clamp mechanism, in cases where an aneurysm (vessel dilation) and / or dissection (tearing of the layers forming the vessel wall) develops in any section of the aorta, and where the damaged aortic tissue is to be replaced with an artificial vessel.

An artificial graft for anastomotic coupling is provided. The artificial graft includes a tubular body forming a lumen and one or more joining features operable to couple with a joining feature coupled with a tubular structure. When the joining feature is coupled with the joining feature of the tubular structure, the lumen is in fluid communication with a lumen of the tubular structure.

The invention relates to the field of medical biological materials, and discloses a magnetic field guided bionic nerve bundle membrane network artificial graft and a preparation method thereof. An inner core of the magnetic-field-guided bionic nerve bundle membrane network artificial graft is an axially-oriented micron-sized fiber network, and an outer layer of the magnetic-field-guided bionic nerve bundle membrane network artificial graft is a polyethylene glycol diacrylate chitosan composite fiber layer. The bionic bundle membrane-like fiber network can realize full-time efficient repair and regeneration of peripheral neuropathy, the micron-sized distributed axial orientation fiber network provides support for cells, silk fibroin loaded on the fiber provides anchoring points for vascular endothelial cells and Schwann cells, myelination and orientated growth of axons are accelerated, and the application prospect is wide. And high-quality repair of injured / diseased nerves is realized.
