At least half of patients with X-ALD are adults with somewhat milder manifestations, and women who are carriers may become symptomatic. X-ALD is often misdiagnosed as attention-deficit/hyperactiity disorder in boys and as multiple sclerosis in men and women, and is not an uncommon cause of Addison disease;(2) the incidence of X-ALD, estimated to be 1:17 000 in all ethnic groups, approximates that of phenylketonuria;(3) noninasie and presymptomatic diagnosis and prenatal diagnosis are aailable; family screening and genetic counseling are key to disease preention; and (4) new therapies, applied early, show promise.
至少1半的X-ALD为成年病人,表现较轻,而作为携带者的女性也可发病。X-ALD在男孩常误诊为注意缺陷/多动综合征,男女可误诊为多发性硬化,并且也是Addison病的病因;(2)据估计X-ALD发病率为1:17 000,类似于苯丙酮尿症;(3)可进行无创性、症状前诊断和产前诊断;家系筛查和遗传咨询是疾病预防的关键;(4)早期采用新的治疗方法非常具有前景。

Results AE from CM had vasodilating effect on the contracti on of mesentery blood capillary in guinea pigs and the contraction of rat thoracic aortic ring induced by l0μmol/L phenylephrine, even under the condition of pre-treating with glibenclamide (1μmol/L) or propranolol (3μmol/L). When the endothelium of the rat thoracic aortic ring was removed, AE from CM had not vasodilating effect hut constrictive effect. AE from CM could also increase the contents of NO, NOS and cNOS in the aortic tissue and had no obvious effect on the NO content in plasma and iNOS in aortic tissue of rats.
