Sensory nerves supplying the deer antlerogenic region were sectioned about 60 days prior to pedicle initiation to determine the extent of neural influence on pedicle and first antler growth. Our results from a combination of histological examination and immunohistochemical localization showed that all 12 antlerogenic regions were successfully deprived of sensory nerve supply, but in 10 of 12 cases there was partial regeneration during the experimental period. In the two cases where no sensory reinnervation occurred, pedicle growth did not show any differences compared with partially sensory reinnervated or intact pedicles. With or without reduced sensory nerve supply, first antlers were initiated, grown, cleaned of velvet, cast, and regenerated in the normal way, but they were smaller than controls. Consequently, we conclude that a sensory nerve supply is not necessary for normal pedicle formation and for the first antler cycle, but plays a role in determining antler size.
在鹿茸发生区的蒂部开始生长前约60天切断供应该区域的感觉神经，以确定神经对蒂部和初角生长的影响程度。我们通过组织学检查和免疫组化定位相结合的结果表明，所有12个鹿茸发生区均成功切断了感觉神经供应，但在12例中有10例在实验期间出现了部分再生。在没有感觉神经再支配的2例中，蒂部生长与部分感觉神经再支配或完整的蒂部相比没有显示出任何差异。无论感觉神经供应是否减少，初角均以正常方式开始生长、脱茸皮、脱落和再生，但它们比对照组小。因此，我们得出结论，感觉神经供应对于正常的蒂部形成和初角周期不是必需的，但在决定鹿茸大小方面起作用。
