Natural history of extensive Mongolian spots in mucopolysaccharidosis type II (Hunter syndrome): a survey among 52 Japanese patients

BACKGROUND: Recent reports have shown a correlation between extensive Mongolian spots and mucopolysaccharidosis type II (Hunter syndrome). However, a statistical survey of the incidence and natural history of extensive Mongolian spots among the patients with Hunter syndrome is lacking. OBJECTIVES: To determine the prevalence of extensive Mongolian spots, to determine the natural course of the spots according to age in Japanese patients with Hunter syndrome, and to compare them with the results obtained from the patients' brothers who did not have Hunter syndrome. PATIENTS/METHODS: Fifty-two males with Hunter syndrome aged 3 to 40 years were studied. Twenty-five patients were examined in two clinics to determine the existence and characteristics of the spots. We interviewed their families about the spots in their neonates and the natural course of the spots according to their ages. The same survey was done among another 27 patients using a mailed questionnaire to their families. As control, we investigated 21 brothers of the patients by a mailed questionnaire to their families. RESULTS: The extensive Mongolian spots are identified in almost all the infants with Hunter syndrome and disappear extremely later in their life. The lesions had a high incidence of deep-blue hyperpigmentation. Regardless of age, the overall incidence was 78%. All of the brothers who did not have Hunter syndrome had common-type Mongolian spots in neonates, which regressed during their childhood. CONCLUSION: Our results confirm a strong correlation between extensive Mongolian spots and Hunter syndrome for the Japanese population. The presence of extensive Mongolian blue spots should alert the physician to the possibility of Hunter syndrome.

１９８８～１９９１年对内蒙古锡盟地区３８９例蒙古族新生儿进行了活体观察测量，取得了２２项总体发育指标及相应的各项性别指标的均值数据，并以其中体重、身长、顶臀长（坐高）、头围、胸围及上臂围等６项指标与国内外有关资料作了比较和性别间的对比分析，从结果来看，体重高于本地区平均水平１１０ｇ，高于国内某些城市１４０～２０２ｇ；身长及坐高分别矮于本地区平均水平５．１３ｃｍ及６．５４ｃｍ，分别矮于国内某些城市４．８８～４．８９ｃｍ及６．６０ｃｍ。呈圆头型、手足宽短、身躯宽短的粗壮体型。     

Synaptosomal Na, K-ATPase during forebrain ischemia in Mongolian gerbils

We studied the activity and kinetic parameters of synaptosomal Na, K-ATPase during 15 min of forebrain ischemia and following 60 min of reperfusion produced by reversible common carotid occlusion in Mongolian gerbils. A synaptosomal fraction was obtained by both differential centrifugation of brain tissue homogenate and centrifugation of crude mitochondrial fraction at a discontinual sucrose density gradient. We found two components of ATP concentration dependence of ATP hydrolysis that represent two types of ATP-binding sites: high affinity and low affinity. Neither ischemia nor reperfusion affected kinetic parameters of a high-affinity site. However, lowaffinity site parameters were affected by both ischemia and ischemia followed by reperfusion. Maximal velocity (V _max) decreased by 43 and 42% after ischemia and after ischemia/reperfusion, respectively. The apparentK _m for ATP decreased by 52% after ischemia and by 47% after ischemia/reperfusion. The apparent affinities for K⁺ and Na⁺ were determined from the ATP hydrolysis rate as a function of Na⁺ and K⁺ concentrations. We found the half-maximal activation constant for K⁺ (K _a K⁺) increased by 60% after ischemia and by 146% after ischemia/reperfusion. On the other hand, we found thatK _aNa⁺ decreased significantly after ischemia/reperfusion (16%). We concluded that it is the dephosphorylation step of the ATPase reation cycle that is primarily affected by both ischemia and ischemia/reperfusion. This might be caused by alteration of the protein molecule and/or its surroundings subsequent to ischemia.     

黄芪丹参复方成分对一氧化氮合成阻滞孕鼠模型血浆IL-1、IL-10变化的影响

目的探讨黄芪丹参复方成分提高胎盘血供的分子机制，为临床有效防治胎盘血供不足所致妊娠并发症提供思路。方法提取分离黄芪、丹参复方成分，运用NOS（一氧化氮合酶）阻滞剂L－精氨酸甲酯（L—NAME）建立一氧化氮合成阻滞大鼠模型，ELISA法检测妊娠18d大鼠血浆IL－1、IL－10水平。以及胎盘超微形态学变化，大鼠血压、尿蛋白变化，以及仔鼠重、肝重、脑重、胎盘重等。结果一氧化氮合成阻滞模型组IL－1含量明显高于空白组（P〈0．01），经黄芪丹参注射液治疗后，血浆IL－1水平比模型组降低（P〈0．05）；模型组IL－10含量较空白组低（P〈0．01），中药组血浆IL－10水平高于模型组（P〈0．05）；胎盘形态学、血压、尿蛋白以及仔重、仔肝重、脑重等均有显著差异（P〈0．05，P〈0．01）。结论黄芪丹参复方成分可能对妊娠早期母－胎界面免疫平衡具有调控作用，通过促进局部生理抑制性免疫反应增强和杀伤、排斥免疫反应减弱，从而有利于母胎循环构建，维持胎盘血液供应。

Cerebral ischemia induces transient intracellular redistribution and intranuclear translocation of the raf proto-oncogene product in hippocampal pyramidal cells

Summary In this report we describe changes in the intracellular redistribution of raf serine/threonine protein kinase (product of the raf proto-oncogene family) in hippocampal neurons following cerebral ischemia in Mongolian gerbils. For immunohistochemical localization studies polyclonal antisera specific for each of the A, B, and Raf-1 isotypes of raf, as well as a pan-raf antisera, were employed. Of these, only sera recognizing B-raf, as well as the general v-raf (raised against the conserved C-terminal region) were positive, indicating that B-raf is the major isotype in this neuronal region. Three different ischemie models were used (repeated 3 times for two min and single 5 or 15 min occlusions, of the common carotid arteries) to demonstrate that ischemie insult causes redistribution of raf protein kinase into the cell nucleus of hippocampal neurons. Increased amounts of raf protein in the nuclei of pyramidal cells following ischemia was confirmed by Western blot analysis of isolated nuclear fractionations. Moreover, an elevation in the level of nuclear raf protein also was detected in the contralateral (i.e. non-occluded hemisphere) neurons of CA1 and CA3 subfields 4 days after the ischemie insult indicating a possible transsynaptic increase in the amount of raf protein along with redistribution. The intranuclear translocation of the immunoreactive material started from the perinucleolar rim and with time extended throughout the nucleus. Enhanced levels and altered redistribution of the raf polypeptide in the nuclei of pyramidal cells of the CA3 subfleld appears to be reversible and returns to the normal level 12 days following the ischemic insult. In addition to triggering the above changes in the intracellular redistribution of raf, ischemie insult also caused an increase in the level of B-raf protein in reactive astrocytes.
