1 alpha,25-dihydroxyvitamin D3 [1 alpha,25(OH)2D3] directly induces both fusion and cytotoxicity in murine alveolar macrophages. Unlike 1 alpha,25(OH)2D3, retinoic acid per se did not induce fusion of alveolar macrophages, but it greatly enhanced the

The multinucleation process of isolated alveolar macrophages induced by 1 alpha,25-dihydroxyvitamin D3 [1 alpha,25(OH)2D3] was examined using a scanning electron microscope (SEM) and a transmission electron microscope (TEM). At the beginning of cultu

The agriculture development of Ishikari River down stream plains began at early period of Meiji. It was the important measure of the country, and we had many plans for such development programs. However, the prewar development speed was very slow bec

The Golgi apparatus (GA) is a membranous organelle composed of stacked cisterns with associated vesicles. This study was undertaken to determine its origin in rat parotid acinar cells. The morphogenesis of the GA could be recognized in the developmen

Visualization of water transport in cells, tissues and organs is an important, yet still difficult, task in morphological science. By using confocal microscopy and the fluid-phase fluorescent tracer technique, we visualized water secretion and estima

Rat parotid acinar cells were perfused in small quartz columns to examine the role of cAMP and Ca(2+) in the priming and fusion/exocytosis of amylase secretion. Carbachol (CCh) evoked a biphasic response of amylase secretion with an initial rapidly o

Organ function requires coordinated multicellular activities, which may require proper control of cell signalling dynamics at the supracellular level. By using high-speed confocal microscopy, we studied how calcium signalling is organised in the diss

We treated surgical specimens of human parotid and submandibular glands in vitro to manipulate the receptor-signaling cascade pharmacologically and analyzed cellular responses by light microscopy on epoxy embedded sections. Treatment of specimens wit

Amylase secretion from rat parotid acinar cells is regulated by at least two distinct mechanisms (Butcher & Putney, 1980; Putney, 1986). Activation of the β-adrenergic receptor by isoproterenol (isoprenaline), the effect of which is mediated by cAMP

A new model for the subcellular basis of parotid secretion is presented in this article. GM(1)-ganglioside, typically found in neural tissues, is shown to be abundant in the parotid gland. This ganglioside may play a central role in membrane turnover
