Night lighting and microwave exposure have been influence on structures of stress realization. The endocrine, fotoperiodical and adaptive functions of rodent submandibular salivary glands belonging to hormone produced duct cells. To evaluate their morphofunctional state at guinea-pigs and rats using the methods of light and electron microscopy there have been analyzed striated and granular ducts. It has been revealed that instant and twenty-four-hour strengthening of duct cell stress induced secretory activity was similar. It is concluded that salivary glands take part in circadian expectations to stress.

Old Rats

The effect of melatonin on the submandibular salivary glands of old rats was studied using 20 control and 20 experimental rats which had received melatonin daily for 5 months. The glands were first weighed and then processed for light and electron microscopy. The glands of the melatonin rats were significantly heavier than the controls. With light microscopy, the control group showed a loss of normal architecture of the acini and multiple degenerative changes whereas in the melatonin group the acini had clear architecture and few degenerative changes. With electron microscopy, the control group again showed degenerative changes and little cellular activity whereas the melatonin group had features which indicated increased cellular activity

Topographical Relief

The structure of insect salivary glands has been extensively investigated during the past decade; however, none have attempted scanning electron microscopy (SEM) in ultrastructural examinations of these secretory organs. This study correlates fine structure by means of SEM cryofractography with that of thin-sectioned epoxy embedded material observed by means of transmission electron microscopy (TEM).Salivary glands of Gromphadorhina portentosa were excised and immediately submerged in cold (4°C) paraformaldehyde-glutaraldehyde fixative1 for 2 hr, washed and post-fixed in 1 per cent 0s04 in phosphosphate buffer (4°C for 2 hr). After ethanolic dehydration half of the samples were embedded in Epon 812 for TEM and half cryofractured and subsequently critical point dried for SEM. Dried specimens were mounted on aluminum stubs and coated with approximately 150 Å of gold in a cold sputtering apparatus.Figure 1 shows a cryofractured plane through a salivary acinus revealing topographical relief of secretory vesicles.
