Pinocytosis in eyes of a snail, Helix aspersa

Journal of Ultrastructure Research, 1982
Extirpated eyes of the snail Helix aspersa , from which lenses were removed surgically, were incubated in horseradish peroxidase (HRP) and prepared cytochemically for electron microscopy to determine the positions of HRP. There was some internalization of tracer by pinocytic vesicles and tubules in Type I sensory cells and much uptake by Type II ...

Autofluorescence in the retina of a snail, Helix aspersa

Vision Research, 1978
Microvilli (presumed photoreceptoral organelles) and masses of microvesicles, called photic vesicles, in the eyes of a garden snail (Helix aspersa) autofluoresce under u.v. illumination. The fluorescence lasts 20–30 sec. Under the same experimental conditions and procedures the outer segments of rods and cones of the frog Xenopus laevis (control ...

Tissue buffering in the snail, Helix aspersa

Comparative Biochemistry and Physiology, 1970
1. 1. Changes in the concentrations of calcium and bicarbonate in the blood of hydrated Helix aspera, exposed to raised tensions of carbon dioxide or injected with HCl, NaHCO3 or CaCl2, were qualitatively those to be expected if the blood were in equilibrium with solid calcium carbonate. 2. 2.

Differentiation in the eye of a pulmonate snail Helix aspersa

Journal of Ultrastructure Research, 1967
The development of the eye of a stylommatophoran snail, Helix aspersa , was studied by electron microscopy at various stages of morphogenesis from the initial invagination of the embryonic ectoderm to form an eyecup to the fully differentiated organ in the adult.

Ionic regulation in the snail, Helix aspersa

Comparative Biochemistry and Physiology, 1968
Abstract 1. 1. Sodium in the blood of Helix aspera varied between 58 and 138 mM/l. and other cations comparably. 2. 2. In specimens that had fasted 1–11 days and had then been in contact with water for 2 hr, sodium, potassium, calcium and magnesium averaged 68 ± S.D. 6, 2·9 ± S.D. 0·3, 6·2 ± S.D. 1·1 and 3·6 ± S.D.
