ABSTRACT
Objective To investigate the value of D‐dimer (D‐D) ,cardiac troponin T(cTnT) and myocardial enzymogram detec‐tions in clinical diagnosis of acute myocardial infarction (AMI) .Methods 36 cases of AMI patients (AMI group) and 20 cases of healthy people (control group) were selected as study subjects .The plasma levels of D‐D ,cTnT and myocardial enzymogram of two groups were detected ,and the sensibility and specificity of these indexes were analyzed .Results The levels of D‐D ,cTnT ,CK ,CK‐MB ,AST and LDH in AMI group were significantly higher than those of control group (P<0 .05) .The positive rates of cTnT ,D‐D and myocardial enzymogram in AMI patients were 91 .67% ,69 .44% ,and 66 .67% ,respectively .The positive rate of cTnT was significantly higher than those of D‐D and myocardial enzymogram (P<0 .05) .Both of the diagnosis sensibility and specificity of plasma cTnT were significantly higher than those of D‐D and myocardial enzymogram (P<0 .05) .Conclusion Comparing with D‐D and myocardial enzymogram ,plasma cTnT has better diagnosis sensibility and specificity .Joint detection of kinds of indexes could improve the accuracy .
ABSTRACT
Objective Adsorption effect of dietary fibers from seaweeds on extrinsic estrogens was studied.Methods The methods included the tests in vivo and in vitro which simulated environments of stomach and small intestine of rat. Results The adsorption effect of four kinds of dietary fibers on estradiol in simulated environments of small intestine was better than that in simulated environments of stomach. The effect of Laminaria japonica was the best. And the rate of adsorption on estradiol was 108 g?g~ -1.It is 1.5,1.8, 3.1, and 3.0 times that of Sargassum,wheat blan,Gracilaria and Eucheuma,respectively. The rates of adsorption on estradiol of four kinds of dietary fibers from Gracilaria, Eucheuma, Sargassum and laminaria japonica was 11.1%,13.6%,27.5% and 38.7%, respectively. Adsorption rate of Sargassum and laminaria japonica was 1.9 and 1.3 times than that of wheat bran, respectiveiy which was 20.4%. While for Gracilaria and Eucheuma, adsorption rate was lower than that of wheat bran. Conclusion The dietary fibers from four seaweeds showed adsorption effect on extrinsic estrogens. The dietary fibers from brown seaweeds (Sargassum and laminaria japonica) had more adsorption effect than that of red seaweeds (Gracilaria and Eucheuma).
ABSTRACT
Objective:The nutritional value and edible safety were evaluated for fastfood Eucheuma. Methods:The nutritional composition and the contents of heavy metal element and microbiology index were tested, and the test of acute toxicity and mutation were performed to evaluate the nutritional value and edible safety. Results:The main components of fastfood Eucheuma were dietary fibre and mineral components, and the contents of protein and fat were very low. The gross content of dietary fibre was 88.6%. The contents of Zn and Ca were the highest among the mineral components.The index of heavy metal elements and microbes(cfu) were lower than that of the national standard. It was non-toxic and non-mutagenic. Conclusion:The fastfood Eucheuma is a functional food, and also a safe food of new resource.
