1 Benzidine staining can be used to get an approximate estimate of "viable" pollen.

2 NO content and NOS activity were assayed with benzidine fluorescence spectrophotometry.

3 Benzidine staining positivity increase . Conclusion HMBA and HMBPA can inhibit MELDS 19 cell proliferation and induce differentiation.

4 The acute and chronic toxicities of benzidine to Daphnia magna were studied.

5 In this paper, benzidine, C-tolidine and benzidine hydrochloride are determined by anodic differential pulse voltammetry on a glassy-carbon electrode.

6 The inhibition of benzidine on the photodecomposition reaction of 4,4'-diszidobiphenylhas been studied.

7 The benzidine yellow G pigment was modified with amphoteric surfactant and fatty acid, and the flowing, wetting and dispersing properties of the modified pigment were determined.

8 The numbers of benzidine positive staining cells were increased after incubation in the HAT selective medium.

9 Methods: The benzidine was replaced with benzidine chloride for chemical differentiation.

10 Previous studies have shown that exposure to benzidine might affect human health, particularly might further induce bladder cancer.

11 This essay provides an introduction of the surface treating of modification of Benzidine Yellow G.

12 The data suggested that the mutation allele of UGT2B7 could affect individual's susceptibility to bladder cancer in the case of benzidine occupational exposure.

13 To investigate the expression of nuclear mitotic apparatus protein 22(NMP22)in workers occupationally exposed to benzidine.

14 Methods To make the growth curve of eryoleukemia cell, count eryoleukemia cell mitosis index and benzidine staining positive percentage when the eryoleukemia cell were exposed to HMBA.

15 This article reports the method and the result about the medical surveillance on the high bladder cancer risk population exposed to benzidine.

16 Objective The comparison of testing fecal occult blood by One step test and Benzidine test.

17 Leather special black LR-N is a noncancerogenic dyestuff instead of benzidine dyes. The dyeing properties were studied by compared experiments. And the most suitable dyeing route was settled.

18 Colorimetric determination of peroxidase activity in fruit tree with benzidine was studied with the leaves of apple, peach,[www.Sentencedict.com] citrus as the materials.

19 METHOD Formation of NO in unit time was measured by benzidine fluorescence spectrophotometry, which was used to determine the activity of NOS.

20 The applicable properties of Leather Black GN, which is a replacement dyestuff of benzidine and causes no cancers is investigated in this paper.
