This study investigated the maximum number of collaterals that can be maintained by 1 axon during regeneration of rat peripheral nerve. The tibial nerve was transected, the proximal residual, with its variable number of axons, was fixed to the distal stump and served as the donor nerve. The number of myelinated axons was calculated after 12 weeks. An(More)
Outgrowth of collateral sprouts from axons is a natural process that arises during development of and regeneration in the peripheral nervous system. Our previous study showed that if there are enough distal endoneurial tubes into which the proximal regenerative axons can grow, one axon can support three to four collaterals, at most. Here, the proximal half(More)
OBJECTIVES Evaluate the effect of an implanted percutaneous left subclavian artery port-catheter drug delivery system for regional chemotherapy of inoperable pancreatic carcinoma. METHODS One hundred and forty patients with inoperable pancreatic carcinoma were enrolled and randomized into two groups to receive the FAM regimen on a 6-day cycle at 1-month(More)
This study aims to estimate the effects of using a portion of a nerve trunk to repair itself and the injured nerve simultaneously. Proximal 1/2 median nerve served as donor nerve to repair the distal 1/2 median and whole ulnar nerve. Four months postoperation, the number of myelinated axons and nerve conduction velocities of the distal half median and ulnar(More)
To study the genetic polymorphism of nine short tandem repeats (STRs) loci (DXS7130, DXS7132, DXS6804, DXS7423, DXS7424, DXS6789, DXS6799, DXS8378, and HPRTB) on X chromosome in Chinese Yugur ethnic group. The allele and genotype frequency of nine X-STR loci among 120 unrelated individuals (55 female, 65 male) from Yugur ethnic group were analyzed using PCR(More)
This study aims to estimate the effects of using one donor nerve to repair the injured nerve and itself simultaneously by biodegradable chitin conduit. Proximal median nerve served as donor nerve to repair the distal median and whole ulnar nerve. Four months postoperation, the number of myelinated axons and nerve conduction velocities of the distal median(More)
