In the rapid ampoule determination of low concentration iron in water phenanthroline is used as developing agent.
Test results, using two different assays, showed high antibody titer for H5N1 on consecutive serum samples taken on days 11 and 15 of his illness.
Bacteriophages are also assayed by a plague assay method based on similar principles.
Abstract: The efficacy of 1368 Streptomyces isolates for controlling cucumber seedling blight diseases caused Phytophthora melons Kalsura were screened and evaluated in greenhouse.
At present, the main methods used in the study on Chinese traditional medicine in gastrointestinal dynamics animal experiment are gastric emptying and small intestine motional rate mensuration, parent electric bridge strain gauge mensuration, gut hormone determination (GAS, MOT, SS et), immunohistochemical method, excised gastrointestinal smooth muscle dynamoscopy, intragastric and intestine pressure tracing.
All the samples were investigated with reference to the requirements and the method for Theophylline extended-release capsules in the twenty-third edition of United States Pharmacopoeia.

AbstractIn the present study,cerebrospinal fluid levels of arginine vasopressin in 2cases with stroke and 1physically and mentally healthy age-matched persons were determined radioimmunoas-say(RIA). The result showed that the CSF level of AVP in patients with thrombosis and embolism were increased when com pared with that of the healthy group. It suggests that AVP may in-volved in the occurence and development of cerebrovascular diseases.
At the end of the evperiment, cacullating the CDCD8~+ and CD4~+/CD8~+ of the mice thymus were observed the way of McAb indirect immunofluorescence, detecting the secretive antibody capacity of the spleen and the hemolysin level of blood serum with the method of QHS and spectrophotometer, observing the function of anti-inflammafory and abirritation.
A method for determining L-tryptophan room temperature phosphorimetry using filter papa as the solid substrate and NaI as the heavy atom perturber is described. The measurement is carried out in the presence of Na_2CO_without passing any drying gas. The limit of detection is 0. ng.
