RESUMO
Objective To explore the application of steatosis liver donor (SLD) in piggyback liver transplantation (PBLT). Methods Sixty-four cases of SLD were subjected to PBLT and classified into light steatosis liver (S1,22 cases),moderate steatosis liver (S2,25 cases),and severe steatosis liver (S3,17 cases) groups.Eighty cases of non fatty liver selected randomly in the same period served as controls. The liver and renal function at the day of surgery,postoperative liver function recovery,complications one month after surgery,and the death of recipients were recorded.Results There was no significant difference in the liver and renal function between steatosis liver groups and control group at the day of surgery (P＞0.05). At 21st day after surgery,the liver function of 95％ recipients in control group returned to the normal level,and the liver function recovery rate in S1,S2 and S3 groups was 90.9％,80.0％,and 70.6％ respectively.Graft primary nonfunction occurred in 2 cases (11.8％) of S3 group. The incidence of complications such as bleeding,infection,hepatic artery thrombosis,ascites,sepsis in S1,S2 and S3 groups was higher than in control group (P＜0.05).One year after operation,there were two deaths in control group,one in S1 group,one in S2 group,and 5 in S3 group,respectively.Conclusion SLD can be used for transplantation,but for the transplantation with severe steatosis liver,it should be carried out carefully.
RESUMO
Polysaccharide was extracted by boiling water reflux method from the fruiting body of Ganoderma lucidum. Additionally, the purified polysaccharide was obtained by removing protein with Sevage way, ethanol precipitation, centrifugation, run water dialysis, membrane separation, concentration and frozen-drying. The structural characteristics, chain conformation and triple-helix conformation of ganoderma lucidum polysaccharide (GLP) were distinguished by Smith degradation, methylation analysis, and the wavelength change of the red shift of the mixture of polysaccharide and Congo red in alkaline solution, as well as IR, GC-MS, NMR, and visible spectrometry. The results indicated that GLP was a linear (1→3) β-D-Glcp main chain linkage. Its monosaccharide component was predominantly composed of D-Glc, and small amount of galactose, mannose, xylose and idose, residues of branches terminated with substituted at 1→6 by a small number of single-unit β-D-Glcp side-chains, it′s also observed that the (1→3)-linked β-D- glucan contained a triple-helical conformation, which was composed of a repeating unit with a structure as below:→3)-β-D-Glcp-(1→3)-[β-D-Glcp-(1→3)-]_n-β-D-Glcp-(1→.↑6/1β-D-Glcp
RESUMO
Objective To explore the effect of prevention and treatment of external application of Algoplaque for controlling phlebitis caused by peripheral indewelling needle in vein for patients. Methods This research was divided into two parts,prevention and treatment. As for prevention research,patients were randomly divided into the experimental and the control groups,each group included 30 patients. In the experimental group,we applied directly external application of Algoplaque at the upper of needle puncture site of the vein and nearby the eye. In the control group,we applied the film directly to fix the indwelling needle. As for the treatment research, it was carried out in patients with occurred phlebitis, who were randomly divided into two groups,the experimental group included 30 cases of patients and the control group included 28 cases of patients. Observation time was one to five days. Results The incidence of phlebitis in the experimental group of prevention research was 23%, in the control group it was 90%. The incidence of phlebitis in the experimental group was significantly lower than that of the control group. The effective rate in the experimental group of treatment research was 96.7% and it was 67.9% in the control group. The difference was very significant. Conclusions External application of Algoplaque can effectively control phlebitis caused by peripheral indewelling needle in vein.
RESUMO
The better conditions for flask fermentation of Grifola frondosa are:QF medium.25℃.pH4 5 filled volume 60mL/500mL flask.rotated speed 100rpm.When 0 4%CMC is added to medium,the growing point of mycelia can increase and the biomass is rised.Scale\|up test has done in 10 litre airlift bioreactor.The rate of biotransformation between biomass and original sugar or between biomass and consuming sugar is over 24% or up to 435%.In mycelium the polysaccharide content is 10 2%.In culture fluid the polysaccharide content is 1 38%.
RESUMO
Objective To analyze the nutritional composition of lipids in silkworm chrysalis (Bombyx mori L.). Method Crude lipids were extracted by chloroform/methanol, and fatty acid, tocopherol, sterol and phospholipid composition in silkworm chrysalis were determined by GC, HPLC and TLC methods. Results Silkworm chrysalis was rich in lipid (32.79%) in which the most abundant fatty acids were C18:3 (32.79%), C18:1 (32.53%), C16:0 (22.42%), but C18:2 (4.37%), C18:0 (5.73%) and C16:1 (0.57%) were relatively less. The sterols included cholesterol (67.35%), ?-sitosterol (19.21%), and trace amount of campesterol (0.28%) and brassicasterol (0.30%). Total tocopherols detected were at an average concentration of 486 mg/kg, including ?-tocopherol (44.85%), ?(+ ? )-tocopherol (44.57%), and ?-tocopherol (10.85%). The phospholipid content was about 1.17mg/g, among which, phosphorylcholine about 41.8%. Conclusion Silkworm chrystalis (Bombyx mori L.) could be a good source of nutritional edible oil rich in unsaturated fatty acid, phospholipids, phytosterols and tocopherols, particularly ?-linolenic acid, ?-sistosterol and ?-tocopherol.
