Mice were orally administered IOP for a period of 14 days at 0,100,200 and 300 mg/kg/d,and were assigned to the control,IOP-100,IOP-200,and IOP-300 groups,respectively by the random number table method. Mice in the control group received an oral administration of sterile distilled water. A forced swimming test was performed for 8 mice per group at one hour after the last treatment. The other 8mice in each group swam for 30 min. Blood,liver and muscle samples were taken after resting for30 min. Levels of blood urea nitrogen and lactate,as well as glycogen contents of the liver and muscle were measured. Morphology of liver was observed by light microscopy.RESULTS: IOP extended the swimming time of mice,and increased the glycogen content of liver and muscle,but decreased blood lactic acid and serum urea nitrogen levels. IOP had no toxic effects on major organs such as the liver as assessed by histopathological examinations.CONCLUSION: IOP might be a potential anti-fatigue pharmacological agent.展开更多

All the 3 groups had been supplied with nitrogen and caloricity according to the need of patients for 16 days. The rhGH therapy started 48 h after surgery and lasted for 14 days in two rhGH-treated groups in which rhGH was 0.2 and 0.4 U/(kg·d) respectively, and the resting group served as control one. The levels of nitrogen balance, prealbumin and safety variables (blood sugar, Na+, TT3 and TT4) were observed and com- pared among the three groups. The levels of nitrogen balance on the postoperative day (POD) 3 and 5 in the rhGH-treated groups were -1.28±3.19, 5.45±2.00 and -0.18±2.55, 6.11±1.60, respectively, which were significantly higher than those in the control group (-5.17±1.68 and -1.08±3.31, P<0.01). The values of prealbumin on the POD 3 and 5 in the rhGH-treated groups were 180.19±27.15, 194.44±50.82 and 194.94±29.65, 194.11±16.17, respectively, which were significantly higher than those in the control group (117.42±19.10 and 135.63±28.31, P<0.01). There was no sig- nificant difference between the rhGH 0.2 U/(kg·d) group and rhGH 0.4 U/(kg·d) group in both of the levels of nitrogen balance and prealbumin. It is concluded that the nutritional support therapy with adjuvant rhGH which starts 48 h after surgery improves the nutrition state of the patients with severe multiple trauma. It is safe for severe multiple trauma patients who accept rhGH at the dose of 0.2 and 0.4 U/(kg·d).展开更多
