ABSTRACT
To examine the effects of different temperature on preservation damages of red blood cells in liquid blood. Blood samples were taken from 10 healthy blood donors and divided each sample into 2 groups, the fresh blood was put into CP2D A solution at 0℃ and 4℃, and the samples were taken after 21 days and 42 days, and then the contents of membrane phospholipids were measured with shafiq UR rehman method, of CaM with purification PED test, of LPO with spectrophotometry. Results showed that at the same temperature, when the preservation time was prolonged, peroxidation was increased, the preservation damages were also augmented; the damages were declined when the temperature was lower during the same period, the aging of blood was more evident at 4℃. It is suggested that the 0℃ group is better than 4℃ group.
ABSTRACT
Objective To study the possibility of endoscopic thyroidectomy. Methods Benign thyroid tumors, with diameter between 22 mm and 38 mm, were successfully removed in 8 patients by endoscopic thyroidectomy through anterior chest wall. Results The mean operation time was 120 min (range, 60 min～180 min), and the mean intraoperative blood loss was 20 ml (range, 10 ml～50 ml). No intraoperative or postoperative complications occurred. And no scars remained. Conclusions Endoscopic thyroidectomy through anterior chest wall is a safe and effective procedure for benign thyroid tumors, with excellent cosmetic results in the neck postoperatively.
ABSTRACT
In this case-control study, the effect of insulin sensitivity on the genesis of cholesterol gallstones was not affirmed. However, raised 2h insulin level during glucose tolerance test and systolic blood pressure were risk factors in gallstone formation. Besides, less physical activity, lower serum total cholesterol and lower HDL-C concentration were found in patients with cholesterol gallstone.
