BACKGROUND Severe burns stimulate a hypermetabolic response that causes systemic complications. Propranolol, a nonselective beta-blocker, reduces this response and increases survival. Nevertheless, few studies have shown the effects of propranolol on healing of severe burns. This study evaluated macroscopically and microscopically the effects of the(More)
Sympathetic nerve failure has been proposed as a contributing factor in impaired cutaneous wound healing in diabetes mellitus. Nevertheless, no studies have shown whether beta-adrenoceptor blockade through beta-blocker (e.g., propranolol) administration may alter healing of diabetic cutaneous lesions. This study evaluated macro- and microscopically the(More)
To examine the influence of therapeutic ultrasound (US) on repair of standard and ischemic cutaneous lesions, full-thickness excisional wounds were made in rats and treated with a US 3 MHz, 0.5 W/cm(2) pulsed duty cycle. We used five experimental groups: control (received US powered off on the day of surgery, and on the second and fourth day), control US(More)
Obesity is associated with significant changes in skin combined with metabolic alterations such as insulin resistance. Our aim was to investigate the effects of insulin resistance induced by a high-fat diet on cutaneous wound healing. Male C57BL/6 mice were fed standard chow (SC group) or high-fat chow (HFC group) for 30 weeks. On day 0 (28th week), an(More)
The α2-adrenoceptors regulate the sympathetic nervous system, controlling presynaptic catecholamine release. However, the role of the α2-adrenoceptors in cutaneous wound healing is poorly understood. Mice lacking both the α2A/α2C-adrenoceptors were used to evaluate the participation of the α2-adrenoceptor during cutaneous wound healing. A full-thickness(More)
Recent studies have suggested that mast cell numbers are increased in the skin of patients with cutaneous mucinosis and that these cells may have an important role in angiogenesis and production of mucin. Then, skin biopsies from 30 patients with cutaneous mucinosis (papular mucinosis, focal mucinosis, and mucinosis associated with lupus erythematosus) and(More)
