The effects of 4-HBA on P. subcapitata growth observed in the present study are not expected for planktonic algae in the aquatic environments, because known environmental concentrations are far below the effective concentration range.

By using the present method, an analysis of GSH and GSSG is possible without exposure to any bad odor or the need to distill 2-vinylpyridine and highly accurate results could be rapidly obtained.

The results suggested that the induction of GSH synthesis by HGF is associated with the transcriptional activation of the gamma-GCS gene and the subsequent elevation of gamma- GCS activity.

It is suggested that reduced states of glutathione suppress TE differentiation in Zinnia elegans, and the process of the redox changes in glutATHione is considered to be controlled via GR activity for TE differentiation.

The enzyme activities of cystathionine-β synthase and γ-cystathionease for cysteine synthesis, and ofγ-glutamylcysteine synthetase, which is a limiting enzyme for glutathione synthesis, were clearly increased in regenerating liver, which could be clearly accounted for by the elevation of these enzyme activities.

The results of low levels of gamma-enolase suggested that 1-bromopropane might primarily cause functional or cellular loss of neurons in the cerebrum and cerebellum, and suggested that glutathione depletion or modification to functional proteins containing a sulfhydryl base as a critical site might be the underlying mechanism of 1- bromoprostane neurotoxicity.
