用比浊法分别测定扁桃体切除术前、术后１ 周及１ 个月的免疫球蛋白（ＩｇＧ、ＩｇＡ、Ｉｇ Ｍ） 含量，了解其变化情况。结果显示，术后１ 周ＩｇＧ、ＩｇＡ、Ｉｇ Ｍ 均下降，与术前比较，差异有高度显著性（ Ｐ ＜ ０ ．０５） ；术后１ 个月，Ｉｇ 水平均有所回升，以ＩｇＡ 最明显，其含量与术前相比差异无显著性（ Ｐ ＞ ０ ．０５） ；而Ｉｇ Ｍ 、ＩｇＧ 则不明显，其均数与术前相比差异仍有高度显著性（ Ｐ ＜ ０ ．０５） 。认为扁桃体切除术后Ｉｇ 含量虽有下降，但均在正常范围内变化，故只要掌握好适应证，儿童扁桃体切除是安全可靠的。
The levels of immunoglobulin (IgG, IgA and Ig M) before tonsillectomy, 1 week and 1 month after operation were measured by turbidimetric method respectively to understand the changes. The results showed that the levels of IgG, IgA and IgM decreased 1 week after operation, and the difference was highly significant compared with that before operation (P <0.05). Ig levels rose at 1 month after operation, Obviously, the content was not significantly different from preoperative (P> 0.05), while Ig M and IgG were not significant, the mean difference was still significantly higher than that before operation (P <0.05. ). Although the Ig content after tonsillectomy decreased, but all within the normal range of change, so as long as the indications, children tonsillectomy is safe and reliable.
