The objective of the study was to evaluate the efficacy of an emollient cream enriched with DS water in children with atopic dermatitis (AD). Eighty six AD children were randomized in a double-blind controlled study to receive twice-daily topical treatment with a body cream enriched with DS minerals (TP) compared to two types of control: 1) DM, DS minerals with lower DS water concentrations than TP, and 2) an emollient (E) with no DS minerals. Efficacy was assessed by a change in clinical skin severity scores: SCORing Atopic Dermatitis (SCORAD), investigator’s global assessment (IGA) and patient global assessment (PGA) as well as by objective physiological parameters: transepidermal water loss (TEWL), stratum corneum hydration (SCH), affected body surface area (BSA) and Objective Severity Assessment of Atopic Dermatitis (OSAAD). The total length of the trial was 12 weeks divided to 6 visits at weeks 0, 2, 4, 6, 8, 12. The study showed that both TP and DM creams improved OSAAD scores. Only TP improved TEWL and SCH. TP was the most effective regarding TEWL, SCH and OSAAD compared to DM and E. Treatment with E decreased more significantly IGA score compared to TP. Although within each treatment group significant improvements in SCH, BSA, SCORAD, IGA and PGA were observed, the reduction in BSA, SCORAD and PGA was not significantly different among the groups. Our results clearly show the benefits of TP as a leave on-skin emulsion enrich with DS water in terms of skin barrier function. Thus, TP can serve as an effective adjuvant treatment for AD skin as well as for its maintenance.展开更多
目的研究沙棘油对小鼠变应性接触性皮炎(allergic contact dermatitis,ACD)的治疗作用。方法60只ICR小鼠随机分为6组:空白对照组、模型对照组、高中低3个剂量沙棘油外用组(100%,50%和25%)及阳性药对照组(复方醋酸地塞米松乳膏),每组10...目的研究沙棘油对小鼠变应性接触性皮炎(allergic contact dermatitis,ACD)的治疗作用。方法60只ICR小鼠随机分为6组:空白对照组、模型对照组、高中低3个剂量沙棘油外用组(100%,50%和25%)及阳性药对照组(复方醋酸地塞米松乳膏),每组10只。以2,4-二硝基氯苯(DNCB)致敏和激发建立小鼠ACD模型,耳部皮损情况评分作为模型建立成功与否的指标,在激发后48 h测定各试验组小鼠的耳廓肿胀度和脾指数,并以苏木精-伊红(hematoxylin and eosin,HE)染色观察小鼠耳部皮肤炎性细胞浸润等病理变化情况。结果小鼠耳肿胀度测定结果表明沙棘油高剂量组(9 m L/kg,外用)可明显抑制DNCB诱发的小鼠耳廓肿胀,与模型组比较差异有显著性(P<0.01),与阳性对照组比较差异无显著性(P>0.05),小鼠脾指数测定结果表明沙棘油各剂量组可能通过促进免疫器官发育来发挥一定的免疫调节作用。病理学检查结果表明,沙棘油各剂量组与模型组比较耳组织表皮增厚程度减小,表皮及真皮水肿明显减轻,淋巴细胞浸润明显减少,真皮血管扩张充血现象缓解,抑制炎性细胞浸润。结论沙棘油对DNCB诱发的小鼠ACD有明显的治疗作用,其作用机制有待进一步考察。展开更多
