| Buzhong Yi Qi Wan (Buzhong) is a medicinal herb widely used in Traditional Chinese Medicine to treat the digestive and circulatory systems. Red blood cell and plasma proteins labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this work was to investigate the effects of an aqueous Buzhong extract on the labeling of blood constituents with 99mTc. Heparinized blood (Wistar rats) was incubated in vitro with different Buzhong extract concentrations and 99mTc-labeling was performed. Plasma (P) and blood cells (BC) were separated and soluble (SF-P, SF-BC) and insoluble (IF-P, IF-BC) fractions were isolated. The radioactivity on blood constituents was determined and the percentage of incorporated radioactivity (%ATI) was calculated.... |

| Study with the purpose to examine the effects of duodenal switch (DS), regularly performed in morbidly obese patients, on biodistribution of sodium pertechnetate in several organs of rats. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats. A postoperative significant increase (p<0.05) in mean %ATI/g levels was observed in spleen, pancreas and muscle in group DS rats, as compared to group S and C rats. In the lung there was an increase and in thyroid a decrease in mean %ATI/g of DS rats, when compared to sham rats... |

| Clove (Caryophyllus aromaticus L.) has been used for clinical procedures. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this work was to evaluate the effects of clove extract on the labeling blood constituents with 99mTc and on the morphology of red blood cells. Blood samples were incubated with clove, stannous chloride and 99mTc. Plasma, blood cells, insoluble fractions of plasma and blood cells were separated. The radioactivity was counted and percentage of radioactivity (%ATI) to each blood fraction was calculated. The shape and morphometric parameter (perimeter/area ratio) were evaluated. Clove extract altered significantly (p<0.05) the %ATI of blood constituents and the shape of red blood cells... |

| We examined prevention of surgical site infection (SSI) in a tertiary teaching hospital in northeast Brazil, from January 1994 to December 2003. The survey included 5,742 patients subjected to thoracic, urologic, vascular and general surgery. The criteria for diagnosing SSI were those of the Centers for Disease Control, USA, and the variables of the National Nosocomial Infection Surveillance risk index were used. Data analysis revealed that anesthetic risk scores, wound class and duration of surgery were significantly associated with SSI. A total of 296 SSIs were detected among the 5,742 patients (5.1%). The overall incidence of SSI was 8.8% in 1994; it decreased to 3.3% in 2003. In conclusion, the use of educational strategies, based on guidelines for SSI... |
