[Role of biological protective dressing in microskin grafting in rabbit].

Objective: To study the effect of biological protective dressing made from porcine peritoneum in covering wounds with microskin grafts.

Methods: Twenty New Zealand rabbits were divided into ten couples according to the random number table. Rabbits in each couple underwent surgery at the same time.

[Distribution and vicissitude of drug resistance of Acinetobacter baumannii in burn intensive care unit of Wuhan City Hospital No.3 in three years].

Objective: To study the clinical distribution characteristics and vicissitude of antibiotic resistance of Acinetobacter baumannii (AB), and to look for the risk factors of AB infection in order to provide reasonable reference for the prevention and treatment of its infection.

Methods: Specimens of blood, venous catheters, sputum, wound exudates and pharyngeal swabs from 156 patients hospitalized in our burn ICU from January 2006 to December 2008 were collected and cultured. The clinical distribution and antibiotic resistance of AB were determined and analyzed.

[The histological changes and the revascularization process in the grafted dermal substitutes].

Objective: To observe the revascularization process and histological changes in the dermal substitutes after grafting.

Methods: Twenty-one SD rats were enrolled in the study and were randomly divided into swine acellular dermal matrix (sADM), human acellular dermal matrix (hADM), and artificial dermal equivalent (Integra) groups according to different dermal substitutes grafted underneath the skin of SD rats. The gross appearance of the grafts was observed, and the tissue biopsies were harvested at 2, 3, 4, 7, 10, 14, 21, 30, 60, 90, 120, 150, 180 post grafting day (PGD) for the observation of the revascularization process and their histological changes.
