目的观察电刺激大鼠肋间神经通过脊神经节细胞周围突分支上的轴突反射对生长抑素和促胃液素从胃分泌的影响方洁切断大鼠（ｎ＝１７）左侧Ｔ１０或Ｔ１１肋间神经及其神经根，用放免分析法测定电刺激肋间神经近侧断端前、后的血浆生长抑素和血清促胃液素含量（刺激强度１２Ｖ，波宽０．２ｍｓ，频率４０Ｈｚ，刺激时间２ｍｉｎ～３ｍｉｎ），结果电刺激肋间神经近侧断端导致血浆生长抑素从１６１ｎｇ／Ｌ±４０ｎｇ／Ｌ显著增加到３０２ｎｇ／Ｌ±１７０ｎｇ／Ｌ（Ｐ＜０．０５）和血清促胃液素由１３４ｎｇ／Ｌ±３８ｎｇ／Ｌ显著减少到１０２ｎｇ／Ｌ±３８ｎｇ／Ｌ（Ｐ＜０．０１）结论电刺激大鼠肋问神经可通过轴突反射调节生长抑素和促胃液素从胃的分泌。
Objective To investigate the effect of somatostatin and gastrin on the gastric secretion induced by electrical stimulation of intercostal nerve in the intercostal branches of spinal ganglion cells in the rat by electrical stimulation. Fang Jie (Z = 17) left T10 or T11 rib Nerves and their radicles were measured by radioimmunoassay. Plasma somatostatin and serum gastrin levels were measured before and after the electrical stimulation of the proximal intercostal nerves of the intercostal nerves (stimulation intensity was 12V, wave width was 0.2ms, frequency was 40Hz, stimulation Time 2min ~ 3min), the results of electrical stimulation of intercostal nerve proximal stump end result in plasma somatostatin from 161ng / L ± 40ng / L significantly increased to 302ng / L ± 170ng / L (P <0.05) and serum gastrin (P <0.01) .Conclusion Electro-stimulation of the interlobular nerve in the rat can regulate somatostatin and gastrin from the gastric secretion.
