With in situ DNA hybridization, the EBV genomes have been demonstrated in the labial glands of the Sjogren′s syndrome patients (16/28), moreover the elevated content of EBV DNA has been identified in those with more severe destruction of labial glands. It is concluded that EBV, vhich has a normal site of latency at salivary glands in a nonpathogenic state, may be reactivated in Sjogren′s syndrome patients and play a role in the pathogenesis of this disease.

另外，我们用原位杂交方法观察了EB病毒DNA在干燥综合征病人唇腺组织的存在状况，结果发现28例干燥综合征病人中16例为阳性，其中腺泡组织破坏严重者，EB病毒DNA的含量亦高，并且EB病毒主要分布于大量浸润的淋巴细胞中，其次位于腺泡上皮细胞内，少量见于腺泡腔中，以上结果提示，在干燥综合征病人EB病毒处于活跃的复制状态，干燥综合征病人靶器官受损与EB病毒的活跃复制及其诱导的免疫反应密切相关。

The threshold and latency of CDM-CEP was 85±3.54 dB and 6.59±0.41s in normal control group,90±5.0 dB and 6.68±0.31 s in artificial perilymph group,but could not induce CDM-CEP at 120dB level still in neomycin group.

在短声刺激下，正常大鼠引出CDM-CEP的阈值为85±3.54 dB，阈值时的潜伏期为6.59±0.41s；新霉素组大鼠120dB仍无法引出CDM-CEP；人工外淋巴液组大鼠引出CDM-CEP的阈值为90±5.0dB，阀值时的潜伏期为6.68±0.31s。

Results: Among 32 tested MNs, depolarizing responses(excitatory postsynaptic potential, EPSP) were elicited by cVLF stimulation in 21 MNs, hyperpolarizing response (inhibitory postsynaptic potential, IPSP) in 1 MN, and IPSP preceded by EPSP in 4 MNs. The cVLFEPSPs were stimulus intensity-dependent, and could be abolished by low Ca(superscript 2+)/high Mg(superscript 2+) solution. compared with iVLF-EPSPs, cVLF-EPSPs showed longer latency (P.001). The cVLF-IPSP presented with membrane potential-dependent property and was eliminated by the perfusion of picrotoxin (30 μmol/L) and strychnine (1.0 μmol/L).

结果：在32个测试的MNs，观察到cVLF电刺激可在21个MNs上诱发去极化反应（即cVLF性兴奋性突触后电位，cVLF-EPSP），在1个MN上诱发超极化反应（即cVLF性抑制性突触后电位，cVLF-IPSP），在4个MNs上诱发cVLF-EPSP后复合有cVLF-IPSP的反应。cVLF-EPSP具有刺激强度依赖性、被低钙高镁溶液取消的特性，与i VLF性EPSP相比，有潜伏期较长的特点(P.001)。cVLF-IPSP呈膜电位依赖性，并被印防己毒素(30μmol/L)及士的宁(1.0μmol/L)取消。
