Each group was fed on the diet based on barley with or without added NSP enzymes (0.15%) for a 40-d period. At the end of the experiment the pigs were weighed. Three piglets of each group were chosen and slaughtered. Pancreas, digesta from the distal end of the duodenum and jejunal mucosa were collected for determination. Activities of the digestive enzymes trypsin, chymotrypsin, amylase and lipase were determined in the small intestinal sections as well as in homogenates of pancreatic tissue.Maltase,sucrase,lactase and γ-glutamyl transpeptidase (γ-I-) activities were analyzed in jejunal mucosa.RESULTS:Supplementation with NSP enzymes improved growth performance of piglets.It showed that NSP enzymes had no effect on digestive enzyme activities in pancreas,but decreased the activities of proteolytic enzyme,trypsin,amylase and lipase in duodenal contents by 57.56%,76.08%,69.03% and 40.22%(P<0.05) compared with control,and increased γ-GT activities in jejunal mucosa by 118.75%(P<0.05).CONCLUSION:Supplementation with NSP enzymes in barley based diets could improve piglets' growth performance,decrease activities of proteolytic enzyme, trypsin, amylase and lipase in duodenal contents and increase γ-GT activities in jejunal mucosa.展开更多

METHODS:From 4 366 women who received their annual health check-up,4 211 women were selected for analysis. All 4 211 women were negative for both hepatitis B surface antigen and antibody to hepatitis C virus.Clinical and biochemical variables were examined by using univariate and multivariate analysis. RESULTS:A raised GGT level (>68 IU/L) was seen in 258 (6.1%) of the 4 211 women.In univariate analysis,all variables examined (age,body mass index,blood pressure, hemoglobin concentration,fasting blood glucose, glycosylated hemoglobin Alc,cholesterol,triglyceride,and uric acid) were associated with the elevated GGT level, whereas in multivariate analysis,four variables (age≧50 yr, hemoglobin≧14 g/dL,triglyceride≧150 mg/dL,and presence of diabetes) were significantly and independently associated with raised GGT level.Clinical variables predicting the presence of ultrasonographic evidence of fatty liver were also examined by multivariate analysis;four variables were associated with the presence of fatty liver:BMI≧25 kg/m^2, hemoglobin≧14 g/dL,triglyceride≧150 mg/dL,and uric acid ≧ 7 mg/dL.There was no significant association between the raised GGT level and the presence of fatty liver. Hypertriglyceridemia was significantly and independently associated with both the raised GGT level and the presence of fatty liver. CONCLUSION:Metabolic syndrome seemed to be directly, not indirectly through fatty liver,associated with the raised GGT level in Japanese women.展开更多

Little is known about the mechanisms of Central Nervous System （CNS） involvement in bacterial meningitis. The present study was undertaken to assess the changes in biochemical parameters including glucose, protein, Sialic Acid （SA） and various enzymes like Aspartate Aminotransferase （AST）, Alanine Aminotransferase （ALT）, Creatine Kinase （CK）, Gamma Glutamyltranspeptidase 7 （GGTP） and Lactate Dehydrogenase （LDH） have been determined in the Cerebrospinal Fluid （CSF） of the meningitis patients （n = 26） and compared with control subjects （n = 26）. Total Protein, CK, SA （P 〈 0.02）, AST （P 〈 0.001） and ALT （P 〈 0.0001） of meningitis patients were significantly higher, whereas, glucose （P 〈 0.05） and Gamma Glutamyltranspeptidase （GGT） （P 〈 0.01 and P 〈 0.05, respectively） were significantly lower than those of the controls. This study suggests that loss of integrity of brain-CSF barriers, sialic acid and enzyme profiles may contribute to the severity and neurological complications of meningitis.展开更多
