The opportunity of faster closing deep burn wounds by using fibroblast-like mesenchymal bone marrow stem cells (FMSC) and embryonic fibroblasts (EF) was investigated in rats. It was shown that FMSC as well as EF transplanted onto burn surfaces reduced the expression of cell infiltration but accelerated the formation of vessels de novo and granulation tissue in the wounds. These changes form the conditions for faster closing the burn wounds as compared to the control wounds (without cell transplantation). High rate of wound closing induced by FMSC and EF is thought to be caused by a long period (up to 30 days) of vital activity of the cells grafted on the burn surface. It was also found out that the rate of wound regeneration induced by FMSC was higher that that induced by EF. 相似文献

Background Post thoractomy pain is a major source of concern in the postoperative period. The purpose of this study was to evaluate the
effectiveness of intraoperative temporary intercostal nerve blockade versus thoracic epidural analgesia for control of post
thoracotomy pain.
Methods 40 patients undergoing elective pulmonary resection through a postero lateral thoractomy were randomly allocated to receive
epidural analgesia using 0.25% bupivicaine (Group A, n=20) or temporary intercostal nerve blockade using 0.25% bupivicaine
(Group B, n=20). Adequacy of analgesia was assessed over a period of 24 hours using a visual analogue score and an observer
verbal ranking scale.
Results Pain scores were similar in both the groups for the first 4 hours after surgery. Thereafter, the pain scores were significantly
higher (p<0.05) in Group B as compared to Group A for the remainder of the observation period. There was significantly higher
(p<0.01) usage, of nonsteroidal analgesic consumption in Group B. No neurological complications were encountered, in both
the study groups.
Conclusion We conclude that in the early postoperative period there is no significant difference in pain relief in both the techniques
but there after, epidural analgesia significantly reduces post thoracotomy pain. 相似文献

Background: Optimum pain relief following thoracotomy is essential for patient comfort and to reduce the incidence of postoperative pulmonary
complications.
Methods: A randomized clinical trial was conducted on 90 patients scheduled for pulmonary resection. The patients were randomly divided
into three groups. Group 1 received 0.125% bupivicaine with fentanyl 10μg.ml−1, Group 2 received 0.25% bupivicaine with fentanyl 10μg.ml−1 and Group 3 received only fentanyl 10μg.ml−1 in a calculated dose as a continuous thoracic epidural infusion. Adequacy of anglesia was assessed at rest and during movement
over 24 hours. Analgesic efficacy was assessed using a visual analogue score and an observer verbal ranking scale.
Results: Pain scores were significantly higher in Group 3 during the assessment period. (p<0.01) as compared to the other groups.
The use of intraoperative vasopressors was significantly higher (p<0.05) in Group 2 as compared to the other groups. No neurological
complications were encountered in any of the study groups.
Conclusion: We conclude that in the early postoperative period, the use of 0.125% bupivicaine improves fentanyl epidural analgesia in
patients undergoing lung resection. 相似文献

Background
Obesity is associated with increased cardiovascular morbidity and mortality. A direct effect of isolated obesity on cardiac function is not well established. The study was designed to determine the direct effect of various grades of isolated obesity on echocardiographic indices of systolic and diastolic left ventricular function.Methods
Fifty one obese and 25 normal weight, serving personnel without any other pathological condition were studied. Group I (n=25) consisted of subjects with normal weight and body mass index (BMI <25kg/m2), Group II (n=34) of overweight subjects (BMI 25-29.9 kg/m2) and Group III (n=17) of obese subjects (BMI >30 kg/m2). Echocardiographic indices of systolic and diastolic function were obtained and dysfunction was assumed when at least two values differed by ≥ 2 SD from the normal weight group.Result
Ejection fraction, fractional shortening were increased (p<0.05) in Group II and III. Left ventricular dimensions were increased (p< 0.001) but relative wall thickness was unchanged. Systolic dysfunction was not observed in any of the obese patients. The mitral valve pressure half time (p< 0.01), left atrial diameter (p < 0.01) and the deceleration time were increased (p< 0.01) in obese subjects, while other diastolic variables were unchanged. No difference were found between obesity subgroups. Subclinical diastolic dysfunction was more prevalent among obese subjects. BMI correlated significantly with indices of left ventricular systolic and diastolic function.Conclusion
Subclinical left ventricular diastolic dysfunction was noted in all grades of obesity which correlates with BMI.Key Words: Obesity, Systolic function, Diastolic function, Echocardiography 相似文献9.
