Different approaches are available for the integration of existing health information systems (HIS) in integration projects. Within the PlugIT project in Finland, we have found it necessary to design and implement integration in a collaborative, multidisciplinary and open way. In this paper, we use some generic integration models and relate them to the(More)
Process and activity modeling are widely used in healthcare work and systems development projects. There are various approaches and abstractions available for process modeling. This study describes a four-level approach to activity and process modeling which has been used in modeling healthcare activities in relation to the specification of service-oriented(More)
Both fetal and adult human corneas were subjected to a variety of histochemical techniques for the demonstration of catecholamines. The techniques included both sodium-potassium-glyoxylic acid-induced fluorescence (SPG) and formaldehyde-induced fluorescence after freeze-drying (FIF) procedure. In fetal corneas the presence of adrenergic nerve fibers could(More)
Neurotensin-like immunoreactivity was localized in nerve fibers and terminals of hamster adrenal medulla at light and electron microscopy using the peroxidase-antiperoxidase method. Numerous varicose neurotensin-immunoreactive nerves and terminals were found among nonlabeled cell groups situated peripherally in the adrenal medulla. Combined(More)
