A noradrenergic and serotonergic hypothesis of the linkage between epilepsy and affective disorders

Noradrenergic and/or serotonergic deficits, as well as other abnormalities, may contribute to predisposition to some epilepsies and depressions. Evidence for this hypothesis stems from several sources. Epidemiological investigations are intriguing but incomplete. Pharmacological studies show that noradrenergic and/or serotonergic transmission are both anticonvulsant and antidepressant. Therapeutically pertinent investigations show that antidepressant drugs have anticonvulsant properties, whereas antiepileptic drugs are effective in the management of affective disorders. Additional investigations demonstrate that seizures, whether spontaneously occurring or therapeutically induced, protect against depression. Through studies of innate pathophysiology, noradrenergic and serotonergic deficits have been identified in individuals with depression and in animal models of epilepsy, as well as in some humans with epilepsy. Vagal nerve stimulation, a treatment already known to be effective in the epilepsies, is presently under investigation for effectiveness in affective disorder. New evidence suggests that vagal nerve stimulation exerts at least some of its therapeutic effects through its capacity to increase noradrenergic and serotonergic transmission. Finally, emerging evidence supports the concept that some genetic mammalian models of the human epilepsies exhibit analogous manifestations of depression.

Transconjunctival frontalis suspension (TCFS).

We have devised a frontalis suspension technique originally described in an article entitled, "Transconjunctival frontalis suspension for blepharoptosis" (Trans Am Acad Ophthal Otolaryngol 83:684-92), by Swan and Tongue in 1977. This modified transconjunctival frontalis suspension (TCFS) procedure is described. It has been used at the Oregon Health Sciences University in its original or modified form since 1970. To better understand how this procedure successfully corrects blepharoptosis in patients with poor levator function, a study was undertaken to discern the anatomic relationship of the suspension material to important ocular adnexal structures. The findings are based on gross anatomic dissection and histologic examination of a cadaver eyelid after postmortem transconjunctival fascia lata frontalis suspension. The distal, horizontal limb of the fascia suspends the central portion of the levator aponeurosis in a hammock-type fashion. The two vertical limbs pierce the aponeurosis at the level of Whitnall's ligament and incorporate this ligament. The fascia then exits the orbit through the orbital septum near the arcus marginalis and is incorporated into the frontalis muscle near the junction of the medial one-third and lateral two-thirds of the brow, temporal to the supraorbital neurovascular bundle. This anatomic location is not only relatively easily and safely attained, but also maximizes the principles of more traditional frontalis suspensions while minimizing the effort and surgical manipulation.     

重肌灵对EAMG大鼠血清IL-4、IFN-γ水平的影响

观察中药复方重肌灵对EAMG大鼠血清IL－4、IFN－γ调节作用。方法：采用N2AchR加等量福氏完全佐剂，多次免疫Lewis大鼠，复制EAMG模型，并对模型进行评价。动物随机分为正常组、佐剂组、模型组、地塞米松组和重肌灵组。采用ELISA法观察各组动物血清AchRab、IL－4、INF－γ水平。结果：重肌灵、地塞米松组大鼠血清AchRab滴度、IL－4、IFN－γ水平明显降低，与模型组比较，有非常显著性差异（P＜0.01）。但两治疗组之间无显著性差异（P＞0.05）。结论：重肌灵具有良好的防治EAMG效果，可能是通过下调血清IL－4、IFN－γ，抑制AchRab产生，而起到治疗作用。
