[EX Q]: The appropriateness of vigorous fluid resuscitation to normal blood pressure following hemorrhage in uncontrolled bleeding has recently been questioned due to the possibility of dislodging clots and exacerbating hemorrhage. To develop a rational blood pressure target that maximizes the metabolic benefits of resuscitation without causing increased blood loss, it was first necessary to determine whether there is a reproducible mean arterial pressure (MAP) at which rebleeding occurs. The purpose of this study was to explore the relationship between the rate and time of resuscitation after injury and the rebleeding MAP in an uncontrolled hemorrhage model.', "Sixty-two anesthetized pigs were instrumented with catheters and splenectomized, and suction tubes were placed in the lateral peritoneal recesses to continuously capture shed blood. With the abdomen open, an aortotomy was made in the infrarenal aorta. At either 5, 15, or 30 minutes after the end of the initial hemorrhage, resuscitation with warmed lactated Ringer's solution was begun at either 100 or 300 mL/min. The rebleeding MAP was determined at the moment blood appeared in the suction tubes.", 'The average pressure at the rebleeding point for all animals was MAP = 64 +/- 2, Systolic = 94 +/- 3, and Diastolic = 45 +/- 2 mm Hg. The pressure at which rebleeding occurred in this aortotomy model was not affected by either time of resuscitation (5-30 min), nor was the rebleeding pressure affected by the rate (100 vs. 300 mL/min) of resuscitation.

[EX Q]: Bradykinin is a neuropeptide released after tissue damage which plays an important role in inflammatory pain. The up-regulation of the bradykinin B1 receptor in response to inflammation makes it an attractive target for drug development. Aim was to investigate if the selective B1 receptor antagonist BI113823 reduces inflammation-induced mechanical hyperalgesia and if the effect is mediated via peripheral and/or spinal B1 receptor antagonism.', "Electrophysiological recordings of peripheral afferents and spinal neurons were combined with behavioural experiments to better understand the underlying mechanisms of B1 receptor antagonism. Experiments were performed 24\u2009h after injection of complete Freund's adjuvant (CFA) or saline into the paw of Wistar rats. A gene expression analysis for the B1 receptor was performed in different tissues. BI113823 was administered orally or intrathecally to assess effects on CFA-induced hyperalgesia. Peripheral afferents of the saphenous nerve as well as spinal wide dynamic range (WDR) and nociceptive-specific (NS) neurons were recorded, and mechanosensitivity was measured before and after BI113823 administration.", 'BI113823 reduced CFA-induced mechanical hyperalgesia when administered orally or intrathecally. An increased B1 receptor gene expression was found in peripheral and spinal neural tissue. BI113823 significantly reduced mechanosensitivity of peripheral afferents and spinal NS neurons, but had no effect on WDR neurons.

[EX Q]: Transforming growth factor-beta1 (TGF-β1) is a multipotential cytokine with angiogenic activity. There are only limited data about its role in airway remodeling in COPD. We have previously shown that the reticular basement membrane (Rbm) is hypervascular in the airways of current smokers either with or without chronic obstructive pulmonary disease (COPD). This study evaluated TGF-β1 immunostaining in the Rbm and its relationship to vascularity in smokers with or without COPD.', 'Bronchial biopsies from 15 smokers with normal lung function, 19 current and 14 ex-smokers with COPD were immunostained for TGF-β1 antibody and compared to 17 healthy controls. The percentage area of tissue and also number and area of vessels staining positively for TGF-β1 were measured and compared between groups. Some bronchial biopsies from current smoking COPD subjects were also stained for phosphorylated (active) Smad2/3. Epithelial TGF- β1 staining was not different between COPD current smokers and normal controls. TGF-β1 stained vessels in the Rbm were increased in smokers with normal lung function, current smoking COPD and ex-smokers with COPD compared to controls [median (range) for number of vessels/mm Rbm 2.5 (0.0-12.7), 3.4 (0.0-8.1) and 1.0 (0.0-6.3) vs. 0.0 (0.0-7.0), p<0.05]. Percentage of vessels stained was also increased in these clinical groups. Preliminary data suggest that in current smoking COPD subjects endothelial cells and cells in the Rbm stain positively for phosphorylated Smad2/3 suggesting TGF-β1 is functionally active in this situation.
