EFFECT OF DIFFERENT SALINITIES ON THE CONIFORM CHLORIDE CELLS OF MAYFLY LARVAE
Abstract The larvae of Callibaetis coloradensis can tolerate a fairly wide range of salinities at hypotonic concentrations. However, they are more sensitive to increasing than to decreasing saltExpand
Chloride Cells and Chloride Epithelia of Aquatic Insects
Publisher Summary This chapter discusses recent work on chloride cells and chloride epithelia of aquatic insects, which appear to be functionally analogous to the long-known anal papillae. In insectsExpand
Cell Motility: Mechanisms in Protoplasmic Streaming and Ameboid Movement
Publisher Summary This chapter discusses recent results obtained on amebas and slime-mold plasmodia in the context of protoplasmic streaming and ameboid movement. Ameboid movement is a complexExpand
Typology of ephemerid chloride cells
SummaryThe tracheal gills of 16 species of mayfly larvae were studied with regard to the chloride cells. The ephemerid chloride cells occur as two main types: single cells and cell complexes. TheExpand
Comparative biochemical, histochemical and autoradiographic studies of Na+/k+-ATPase in the rectum of dragonfly larvae (Odonata, Aeshnidae).
Na+/K+-ATPase localization in the rectal wall of larval Aeshna cyanea (Insecta, Odonata) was studied with histochemical precipitation techniques and 3H-ouabain autoradiography in conjunction withExpand
Inhibition of a Cl-/HCO3(-)ATPase in the avian salt gland by furosemide and ethacrynic acid.
An ouabain-insensitive, Mg2+-dependent, chloride- and bicarbonate-stimulated ATPase is present in salt gland homogenates of domestic ducks (Anas platyrhynchos). Furosemide and ethacrynic acid areExpand
Development, cytology, lipid storage and motility of the Malpighian tubules of the nymphal dragonfly, Aeshna cyanea (Müller) (Odonata : Aeshnidae)☆
The Malpighian tubules of nymphal Aeshna cyanea (Odonata : Aeshnidae) were examined by light and electron microscopy. The 1st-instar nymphs have only 3 branchless tubules. With proceeding nymphalExpand
Plasma membranes, cell junctions and cuticle of the rectal chloride epithelia of the larval dragonfly Aeshna cyanea.
The cell membranes and cell junctions of the rectal chloride epithelia of the larval dragonfly Aeshna cyanea were examined in thin sections and by freeze-fracture. These epithelia function in activeExpand

Doses of 1.5 mumol cholesteryl oleate ingested by Aeshna cyanea larvae were partially hydrolysed in the intestinal lumen and the liberated oleic acid absorbed, while free cholesterol and unhydrolysedExpand
Fine structure and function of the rectal chloride epithelia of damselfly larvae.
Abstract Zygopterous larvae posses three epithelial pads in the rectum which show the fine structural organization of ion transporting epithelia. They are directly exposed of the external medium,Expand
