ABSTRACT
Objective: To study the early postoperative nutritional support of the renal transplantation. Methods:The early intake and nutrition were analysed in 64 case who received the operation of renal transplantation. The patients were divided into group A (32 patients, high amount of nitrogen intake) and group B (32 patients, low amount of nitrogen intake) according to the different amount of actural nutritional intake during the period of postoperative three weeks. On the 21st day of post operation, the changes of the nitrogen balance, weight, albumin, hemoglobin, serum lipids and renal function were evaluated. Results:The nitrogen balance of group A was better than that of group B. But there was no significant difference in weight between the two groups. The level of serum albumin of group A was higher than that of group B. But there was no significant difference in hemoglobin level between the two groups. The level of Apro A of group A was higher than that of group B. The improvement of renal function of group A was less than that of group B. Conclusions:The result suggests that the amount of nitrogen intake in early stage of post operation of renal transplantation should be controlled so that the transplanted kidney could work better.
ABSTRACT
Objective:To explore the benefit effects of ?-3 polyunsaturated fatty acids on bone biomechanics in ovariectomized(OVX) rats.Methods: 60 virgin female Sprague-Dawley rats were randomized by the stratified weight method into 6 groups: ① Sham group:deionized water 2 mL/d;②OVX group:deionized water 2 mL/d;③E2 group: OVX +17?-ethinylestradiol 0.1 mg/(kg?d);④ A group: OVX+?-3 PUFAs 75 mg/(kg?d);⑤B group: OVX+?-3 PUFAs 150 mg/(kg?d);⑥ C group: OVX+?-3 PUFAs 300 mg/(kg?d).Each group had 10 rats.After feeding for 90 days,the rats were killed and femur were separated.The maximum load,maximum deformation,elastic load,elastic deformation and energy absorption were measured from three point bending test.Bone wet weights were measured.Result: The femur biomechanics markers of OVX group decreased obviously,while that of all medicated group increased obviously(P
ABSTRACT
Objective: To study the effect of ?-3 polyunsaturated fatty(?-3 PUFA) on the serum lipid of ovariectomized rats.Methods: 60 virgin female Sprague-Dawley rats,3 months of age,were randomized by the stratified weight method into 6 groups: Sham group:deionized water 2 mL/d,OVX group:eionized water 2 mL/d,E2 group: OVX+17?-ethinylestradiol 0.1 mg/(kg?d),A group: OVX+?-3 PUFA 75 mg/(kg?d),B group: OVX+?-3 PUFA 150 mg/(kg?d) and C group: OVX+?-3 PUFA 300 mg/(kg?d).Each group had 10 rats.Experiment period was 90 days.Body weight were measured every week.Serum were collected to measure Cholesterol(TC),Triglyceride(TG),High-density lipoprotein-cholesterol(HDL-C),and Low-density lipoprotein-cholesterol(LDL-C).Results: There were significant difference between groups in the serum lipid.In the OVX group,TC and LDL-C increased.In the E2 group,TC increased compared with that in the Sham group,and HDL-C,LDL-C and HDL-C/TC decreased significantly compared with that in the OVX group.In the A,B and C groups HDL-C/TC increased significantly compared with those in the E2 group.Conclusion: The ovariectomized rats have lipid metabolism disorderd.The ?-3 PUFA and estrogen replacement therapy plays a role in the lipid metabolism.The ?-3 PUFA has the best efficiency in reducing the level of serum lipid.
ABSTRACT
Objective:To study the early postoperative nutrition support of the liver transplantation.Methods:The early intake and nutrition were analysed in 44 patients with liver transplantation . The patients were divided into group A (22 patients , high amount of nitrogen inake ) and group B ( 22 patients , low amount of nitrogen intake ). The changes of the nitrogen balance,body weight, serum albumin, hemoglobin, serum lipids, renal function and liver function were evaluated.Results:There were no significant difference in body weight, serum albumin, hemoglobin, liver function between the two groups. The nitrogen balance of group A was better than that of group B,while the renal function of group B was better than that of group A.Conclusion:The amount of caloric and nitrogen intake in early postoperative stage of liver transplantation should be controlled.
