早期饮食干预对婴幼儿呼吸道变态反应疾病的影响

目的 观察早期饮食干预对婴幼儿呼吸道变态反应疾病发展的影响。方法 选取2003年1月-2004年6月复旦大学附属儿科医院0～6月变态反应疾病高危婴儿176例，在进行环境控制的前提下，随机分为干预组（饮食干预）和非干预组，随访两组患儿变态反应疾病发生、发展的情况。结果 （1）在干预6、12、18个月后，干预组发生两种以上变态反应疾病的人数均显著少于非干预组，过敏症状的严重程度较非干预组也显著减轻（P〈0．005）。（2）饮食干预18个月后，两组患儿在吸入性过敏原筛查阳性比例上的差异没有显著性（χ^2=0．002，P=0．969），但干预组患儿的肺功能显著优于非干预组（P〈0．005）、干预组的食物过敏原筛查阳性比例显著低于非干预组（χ^2=8．91，P〈0．01）。结论 对变态反应性疾病高危婴儿进行饮食干预，能减轻或消除呼吸道变态反应疾病症状，改善肺功能。     

Allergic reactions to raw, pasteurized, and homogenized/pasteurized cow milk: a comparison

Five children aged 12-40 months with IgE-mediated adverse reactions to cow milk (immediate onset clinical pattern of cow milk allergy) were orally challenged double-blind in random order with three different milk preparations processed from the same batch of milk 1) raw untreated cow milk, 2) pasteurized cow milk, 3) homogenized and pasteurized cow milk, and 4) Nutramigen (a commercial hypoallergenic infant formula based on hydrolysed casein) as placebo. Skin prick tests with the same preparations were also performed. On oral challenge the three different processed milk types provoked significant and similar allergic reactions in each child, and no adverse reactions followed the challenge with placebo (Nutramigen). Skin prick test with the same milk products were positive in all children and comparable to the results with an extract of purified raw cow milk protein (Soluprick), whereas Nutramigen did not elicit any skin reactions. A tendency towards a lower threshold of reaction and larger skin reactions induced by the processed milk preparations might indicate an increased ability of pasteurized and homogenized/pasteurized milk to evoke allergic reactions in patients allergic to milk.     

伊柔美白霜对家兔皮肤祛斑效果的观察

目的考察伊柔美白霜的祛斑功效。方法在家兔皮肤上涂抹补骨脂酊，待日光照射使皮肤上形成黄褐斑后，涂抹伊柔美白霜。结果涂抹伊柔美白霜20d后，黄褐斑有明显减退。结论伊柔美白霜具有脱色、增白的功效。     

CLINICAL TRIAL OF EGOCORT 1% CREAM

A double blind clinical trial was conducted with Egocort 1% Cream and plain aqueous cream applied to each half of the body in ten patients with eczema. The patients were assessed for erythema, papules, vesicles, scaling and pruritus at the beginning of treatment, after 7-14 days and again after a further 7-14 days.
The results show that Egocort 1% Cream is more effective in treating eczema than plain aqueous cream. The preparation was found pleasant to use and no side-effects were noted.     

Renal acid excretion in early infancy

In early infancy, complex disorders of acid base metabolism are more frequent than in any other age group, with a predisposition to metabolic acidosis due to an age-related low renal capacity for acid excretion and an unphysiologically high actual renal acid load in nutrition with common formulas. Recently in preterm and small-for-gestational-age infants, persistent maximum renal net acid excretion (NAE) with subnormal or normal blood acid base status, impaired weight gain, and adaptive hormonal reactions have been observed. Incipient late metabolic acidosis is one example of a mixed disorder of acid base metabolism with maximum renal NAE in early infancy. Alkali therapy is highly effective and can be realized both on an individual basis, using urine pH screening as a diagnostic criterium for maximum renal acid stimulation, or on a general preventive level using modified standard formula with a reduced actual renal NAE similar to that seen on alimentation with human milk. From an integrated point of view, the low glomerular filtration rate and renal capacity for acid excretion beyond the developmental age of more than 44 weeks, may well be interpreted as the result of a specific adaptation to breast feeding sparing energy, and thus an evolutionary advantage for the survival of mother and child.

Adhesion inhibitory activity of β-lactoglobulin isolated from infant formulae

β-Lactoglobulin was isolated from infant formulae that were ultra high temperature (UHT) -treated, sterilized or spray-dried. The effect of the isolated β-lactoglobulin on SfaII-fimbriae-mediated adhesion of Escherichia coli to human ileostomy glycoproteins was studied in vitro. β-Lactoglobulin isolated from sterilized formulae was found to perform significantly less well than preparations from spray-dried formulae (p = 0:05). Great heterogeneity was observed in the adhesion inhibitory capacity of β-lactoglobulin isolated from UHT-treated formulae. Therefore, no significant difference was observed between UHT-treated and sterilized formulae or spray-dried formulae (p < 0:10). It can be hypothesized that β-lactoglobulin from spray-dried and some UHT-treated infant formulae may affect the colonization of mucous membranes by E. coli strains causing neonatal septicaemia and meningitis.     

复方红芪减方对周围神经再生影响的实验研究

目的　研究复方红芪提取液进行减方后对周围神经再生的作用。方法　建立钳夹损伤大鼠双侧坐骨神经的动物模型。按术后每日灌服药物的不同将 40只SD雄性大鼠随机均分为 4组。对照组 :灌服生理盐水 ;复方红芪组 :灌服复方红芪提取液 2ml ;减方组 :灌服复方红芪减方后提取液 2ml;补阳还五汤组 :灌服补阳还五汤 2ml。术后 2周及 4周 ,观察坐骨神经功能指数、运动神经传导速度及单位视野有髓神经纤维计数。结果　坐骨神经功能指数 :红芪组和减方组与对照组、红芪组与减方组的差异均有显著意义 (P >0 .0 5 ) ,且减方组优于红芪组 (P >0 .0 5 )。有髓神经纤维计数 :复方红芪组优于对照组 (P<0 0 1) ,减方组明显优于对照组 (P <0 .0 1) ,而红芪组与减方组间无显著差异。运动神经传导速度 :红芪组、减方组、补阳还五汤组与对照组相比 ,均优于对照组 (P <0 .0 5 ) ,但前 3组间无明显差异。结论　复方红芪减方提取液早期可以促进周围神经再生 ,药效更为专一 ,且优于传统方剂补阳还五汤。
