5-ht การใช้

In this study , we use immunohistochemistry , electron microscope , cell culture , image analysis , mtt method and radioimmunoassay to study the localization , varies of quantitation , and possible frictions of 5 - ht and subtype of 5 - htr in human placenta . the results were as follows : 1
5 - ht induced local ca 2 + transients ( ca2 + sparks ) in cultured rat stomach fundus smooth muscle cells ( sfsmc ) was first observed by using the new fluorescent ca2 + indicator stdin and laser scanning confocal microscope . the mechanisms of initiation of ca2 + sparks and propagating ca2 + waves and their relation to e - c coupling were also discussed . 4 . the effects of reactive oxygen species on the spectral properties of the new fluorescent ca2 + indicator stdin were evaluated using four different oxidant - generating systems
Endocrine cells such as argyrophilic cells , 5 - hydroxytryptamine ( 5 - ht ) cells and gastrin cells were distributed in mucous and glandular epithelium of the digestive tract . the amount of endocrine cells was most in the glandular epithelium of stomach and was more in small intestine than that of large intestine and esophagus
