Recovery of Schwann cell-neuronal interactions altered by suppression of endogenous nerve growth factor (NGF) with antibodies to NGF (anti-NGF) was determined by morphometric analysis of unmyelinated and myelinated sensory fibers in the T9 dorsal roots in 3 groups of animals: (1) rats one week after cessation of anti-NGF treatment (anti-NGF + 1WK), (2) rats given antibodies to NGF (anti-NGF) and (3) untreated same age littermates (UNTR). The results indicate that (1) recovery of normal myelination begins within one week of cessation of anti-NGF treatment for small caliber fibers and (2) the observed results of anti-NGF treatment on Schwann cell-neuronal interactions were due to anti-NGF treatment and were not an indirect effect of a general diseased state.
通过对3组动物T9背根中无髓鞘和有髓鞘感觉纤维进行形态计量分析，确定了用抗神经生长因子（NGF）抗体（抗NGF）抑制内源性神经生长因子（NGF）后雪旺细胞 - 神经元相互作用的恢复情况：（1）抗NGF治疗停止一周后的大鼠（抗NGF + 1WK），（2）给予抗NGF抗体的大鼠（抗NGF），以及（3）未治疗的同年龄同窝仔鼠（未处理）。结果表明：（1）对于小口径纤维，抗NGF治疗停止一周内正常髓鞘形成开始恢复；（2）抗NGF治疗对雪旺细胞 - 神经元相互作用的观察结果是由于抗NGF治疗，而非一般疾病状态的间接影响。
