Estudo clínico comparativo entre sutura convencional e vaporização a laser de dióxido de carbono (CO2) em pele de ratos

The proposal of this study was to compare a wound healing between conventional suture and vaporization with CO2 laser in rats skin. ln such case 24 rats were utilized, making two longitudinal incisions in dorsum by scalpel. ln the left side incision the wound was sutured with nylon thread. ln the right side incision the wound were close by approach and vaporized with C02 laser, defocusing, 8 watts in continuous mode. The wound healing was followed by clinical photographic taking at the times: immediately after the procedure, 24 hours, 3, 7, 14, and 21 days. The results showed an early delay of reparation in healing vaporized in comparison with the sutured one, however occurred 21 days both repair tissue showed the same clinical characteristic. This results suggested that the C02 laser can be used by eventual substitute of suture.

Spatial variability structure of soil CO2 emission and soil attributes in a sugarcane area

Soil CO2 emission (F-CO2) is influenced by chemical, physical and biological factors that affect the production of CO2 in the soil and its transport to the atmosphere. F-CO2 varies in time and space depending on environmental conditions, including the management of the agricultural area. The aim of this study was to investigate the spatial variability structure of F-CO2 and soil attributes in a mechanically harvested sugarcane area (green harvest) using fractal dimension (D-F) derived from isotropic variograms at different scales (fractograms). F-CO2 showed an overall average of 1.51 mu mol CO2 m(-2) s(-1) and correlated significantly (P < 0.05) with soil physical attributes, such as soil bulk density, air-filled pore space, macroporosity and microporosity. Topologically significant DF values were obtained from the characterization of F-CO2 at medium and large scales (above 20 m), with values of 2.92 and 2.90, respectively. The variations in D-F with scales indicate that the spatial variability structure of F-CO2 was similar to that observed for soil temperature and total pore volume and was the inverse of that observed for other soil attributes, such as soil moisture, soil bulk density, microporosity, air-filled pore space, silt and clay content, pH, available phosphorus and the sum of bases. Thus, the spatial variability structure of F-CO2 presented a significant relationship with the spatial variability structure for most soil attributes, indicating the possibility of using fractograms as a tool to better describe the spatial dependence of variables along the scale.
