Context: Asteatotic eczema (AE) is characterized by itchy, dry, rough, and scaling skin. The treatments for AE are mainly emollients, usually containing urea, lactic acid, or a lactate salt. N-palmitoylethanolamine (PEA) and N-acetylethanolamine (AEA) are both endogenous lipids used as novel therapeutic tools in the treatment of many skin diseases. The purpose of this study was to compare a PEA/AEA emollient with a traditional emollient in the treatment of AE.', "A monocentric, randomized, double-blind, comparative trial was conducted in 60 AE patients to evaluate and compare the efficacy of the two emollients. The level of skin dryness among the subjects ranged from mild to moderate. The subjects' skin barrier function and the current perception threshold were tested for 28 days by clinical scoring and bioengineering technology.", 'The results showed that, although some aspects were improved in both groups, the group using the emollient containing PEA/AEA presented a better skin surface change in capacitance. However, the most impressive finding was the ability of the PEA/AEA emollient to increase the 5 Hz current perception threshold to a normal level after 7 days, with a significant difference between values at baseline and after 14 days. A current perception threshold of 5 Hz was positively and significantly correlated with skin surface hydration and negatively correlated with transepidermal water loss in the PEA/AEA emollient group.
Answer: Compared with traditional emollients, regular application of a topical PEA/AEA emollient could improve both passive and active skin functions simultaneously.

Context: Neonatal respiratory distress syndrome is a restrictive lung disease characterized by surfactant deficiency. Decreased vascular endothelial growth factor (VEGF), which demonstrates important roles in angiogenesis and vasculogenesis, has been implicated in the pathogenesis of restrictive lung diseases. Current animal models investigating VEGF in the etiology and outcomes of RDS require premature delivery, hypoxia, anatomically or temporally limited inhibition, or other supplemental interventions. Consequently, little is known about the isolated effects of chronic VEGF inhibition, started at birth, on subsequent developing lung structure and function.', 'To determine whether inducible, mesenchyme-specific VEGF inhibition in the neonatal mouse lung results in long-term modulation of AECII and whole lung function.', 'Triple transgenic mice expressing the soluble VEGF receptor sFlt-1 specifically in the mesenchyme (Dermo-1/rtTA/sFlt-1) were generated and compared to littermate controls at 3 months to determine the impact of neonatal downregulation of mesenchymal VEGF expression on lung structure, cell composition and function. Reduced tissue VEGF bioavailability has previously been demonstrated with this model.', 'Triple transgenic mice demonstrated restrictive lung pathology. No differences in gross vascular development or protein levels of vascular endothelial markers was noted, but there was a significant decrease in perivascular smooth muscle and type I collagen. Mutants had decreased expression levels of surfactant protein C and hypoxia inducible factor 1-alpha without a difference in number of type II pneumocytes.
Answer: These data show that mesenchyme-specific inhibition of VEGF in neonatal mice results in late restrictive disease, making this transgenic mouse a novel model for future investigations on the consequences of neonatal RDS and potential interventions.
Does sequestration of Vascular Endothelial Growth Factor ( VEGF ) induce Late Restrictive Lung Disease?

Context: Immunosuppression after burn injury increases the risk of sepsis and multiple organ failure. We examined changes of immune function in mice after burn injury and investigated the immunostimulatory effect of oligodeoxynucleotides containing CpG motifs.', 'Male BALB/c mice (8-10 wk old) received a full-thickness burn to 20% of their body surface area, after which the immunological parameters of splenic macrophages were evaluated. To assess the immunostimulatory effect of oligodeoxynucleotide treatment, splenic macrophages harvested from burned mice were incubated with oligodeoxynucleotides. Then cytokine production and major histocompatibility complex class II antigen expression were measured. To assess the in vivo effect of oligodeoxynucleotides, intraperitoneal administration was done on day 4 after burn injury, and class II antigen expression by splenic macrophages was measured 10 d later.', 'Class II antigen expression and the synthesis of cytokines (interleukin-12, tumor necrosis factor-alpha, interleukin-6, and interleukin-1) by splenic macrophages were significantly reduced after burn injury, while incubation of splenic macrophages from burned mice with oligodeoxynucleotides partially enhanced the production of interleukin-12, tumor necrosis factor-alpha, interleukin-6, and interleukin-1. In addition, intraperitoneal administration of oligodeoxynucleotides enhanced class II antigen expression by splenic macrophages.
Answer: The reduction of class II antigen expression and synthesis of cytokines (interleukin-12, tumor necrosis factor-alpha, interleukin-6, and interleukin-1) by splenic macrophages after burn injury was partially reversed by oligodeoxynucleotide treatment. Therefore, immunostimulatory oligodeoxynucleotides may be a potential treatment for post-burn immunosuppression.
