Electron microscopic changes associated with water absorption in the jejunum

Electron microscopic changes associated with water absorption in the jejunum.

With the electron microscope, mucosal changes induced by the instillation of water into a segment of jejunum of rats were observed. The animals had been deprived of food and water for 24 hours.

Electron microscopic studies in desquamative interstitial pneumonia associated with asbestos.

A case of desquamative interstitial pneumonia (DIP) has been studied by electron microscopy in order to determine the nature of the alveolar cells. Those lining the alveolar walls proved to be granular pneumocytes (type II alveolar epithelial cells) while cells free in the lumen were alveolar macrophages. The brief literature describing the electron microscopic findings in DIP is reviewed. All ...

Electron Microscopic Study of Lepromatous Changes in the Iris.

Changes in the villous pattern of the human jejunum associated with heavy radiation damage.

Influence of sham feeding on salt and water absorption in the human jejunum.

Vagal stimulation induced by sham feeding in 11 healthy subjects was used to examine the possibility that the autonomic nervous system might be involved in the control of human jejunal absorption. Gastric acid secretion was measured from gastric aspirates corrected for recovery, and jejunal absorption was determined using a triple lumen perfusion technique. Sham feeding induced a significant in...
