Ion transport in cultured pig tracheal submucosal gland acinar cells studied by X-ray microanalysis.
The submucosal glands of the airway may contribute more to the airway fluid than the surface epithelium. The cellular mechanisms underlying the regulation of electrolyte and water transport in airway submucosal glands are, however, still poorly understood. Therefore, we attempted to establish a cell culture system to facilitate study of this regulation. Acinar cells were isolated by enzymatic d...
متن کاملPatterns of iron distribution in liver cells in beta-thalassemia studied by X-ray microanalysis.
BACKGROUND AND OBJECTIVES beta-thalassemia is an important public health problem in the countries bordering the Mediterranean sea. One of the major consequences of this disorder, primarily (due to an ineffective erythropoiesis) or secondarily to blood transfusions (which are necessary for the patient's survival), is iron storage. Applying X-ray microanalysis we wanted to demonstrate the differe...
متن کاملChanges in elemental content during apoptotic cell death studied by electron probe X-ray microanalysis.
Recent data suggest that changes in ionic content, primarily potassium, play a pivotal role in the progression of apoptosis. However, the changes in total element content, i.e., sodium (Na), magnesium (Mg), phosphorous (P), chlorine (Cl), potassium (K), and calcium (Ca), during apoptosis have not been evaluated. Electron probe X-ray microanalysis (EPXMA) was used to measure total element conten...
متن کاملLow temperature X-ray microanalysis of calcium in a scleractinian coral: evidence of active transport mechanisms.
Element concentrations were measured by X-ray microanalysis in seawater (SW) compartments and mucocytes in bulk, frozen-hydrated preparations of the scleractinian coral Galaxea fascicularis. Quantitative X-ray microanalysis of polyps sampled in the daytime revealed that concentrations of the elements Na, S, K and Ca were all significantly higher in a thin (10-20 micro m) external SW layer adjac...
متن کاملIon compartmentalization in frog oocytes as demonstrated by X-ray microanalysis.
The distributions of K, Na, Mg and Ca within frog ovarian and oviductal oocytes were studied by electron probe wavelength dispersive X-ray microanalysis. An important heterogeneity could be found both in nuclear and jelly coated oocytes. The highest K, Mg and, to a lesser extent, Na concentrations were found in the pigmented area of the peripheral cytoplasm. There is a certain correlation betwe...
