The effects of endosulfan on the great ramshorn snail Planorbarius corneus (Gastropoda, Pulmonata): a histopathological study

Chemosphere, 2004
In this study the great ramshorn snail (Planorbarius corneus), one of the most abundant gastropod of Turkish limnic systems, was investigated to determine the histopathological effects of endosulfan on the digestive gland, foot and mantle under laboratory conditions.

Two kinds of cholinoreceptors on the membrane of the completely isolated identified Planorbarius corneus neurone

Nature, 1976
WE have found that an identified neurone of the Planorbarius corneus left pedal ganglion (LPed-2 neurone, Fig. 1) responds with depolarisation to nicotinomimetics and with hyper-polarisation to some muscarinomimetics. The LPed-2 neurone of P. corneus contains dopamine1 and is the dopaminergic interneurone sending depolarising and hyperpolarising ...

Individual Growth of Planorbarius corneus (Planorbidae, Gastropoda) in Postlarval Ontogenesis

Russian Journal of Developmental Biology, 2018
Individual growth of 15 great ramshorn snail Planorbarius corneus individuals was studied in aquaculture at 20°С starting from 2 weeks after hatching until the death of the animals. It was demonstrated that the weight of mollusks increases throughout the study period by an S-type curve.

[REACTION OF HAEMOCYTES OF THE MOLLUSK PLANORBARIUS CORNEUS TO A XENOTRANSPLANT].

Parazitologiia, 2015
Tissue reaction of the mollusk Planorbarius corneus to the introduction of a transplant (cat vibrissa) was examined. The transplant was introduced into mollusk tissues with the use of an injection needle. After a day, flattened haemocytes were found on the surface of the transplant.

[Ionic membrane selectivity of Planorbarius corneus mollusk neurons].

Zhurnal evoliutsionnoi biokhimii i fiziologii, 1977
In electrophysiological investigations, relative permeabilities of somatic neuronal membrane in the winkle for K+, Rb+ and Tl+ have been obtained which made it possible to establish the selectivity row for this membrane. This row in principle coincides with similar rows for the membranes of other excitable formations.

Cholinesterase activity in ganglia of gastropoda, Lymnae stagnalis and Planorbarius corneus—II. Histochemical investigation

Comparative Biochemistry and Physiology Part A: Physiology, 1973
Abstract Cholinesterase activity in ganglia of Lymnaea stagnalis and Planorbarius corneus was studied by the direct colouring method of Karnovsky & Roots on cryostat sections. 1. 1. High cholinesterase activity was found in Lymnaea ganglia, while using ATCh or BuTCh as a substrate. 2. 2.

Dependence of size of the great ramshorn (Planorbarius corneus L., Gastropoda, Pulmonata) on population density

Biology Bulletin, 2011
The dependence of the mean mass (M) of great ramshorn (Planorbarius corneus) individuals on the number of individuals (N) that reached 82-days age in culture with constant conditions--water volume 50 ml, temperature 25 degrees C, and redundant food (dandelion leaves)--has been studied.

Elektronenmikroskopische Untersuchung der Zwittergonadenacini von Planorbarius corneus L. (Basommatophora)

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1971
In den Spitzenbereichen der Zwittergonadenacini fertiler Tiere der Pulmonatenspezies Planorbarius corneus sind drei Zelltypen stets gleichzeitig anzutreffen: Oocyten, Spermatiden und Begleitzellen. Die Abgrenzung der Acinusspitze gegen das interacinare Gewebe hin bildet die Basalmembran des wandstandigen Begleitzellepithels.

2009
Enzymes and structural proteins from the muscles (13 loci in total) of the four assumed species of pulmonary mollusks Planorbarius from the reservoirs in vicinity of Zhitomir, Sumy and Vilkovo were analyzed electrophoreticaly in polyacrylamide gels. Not only the absence of differences in allele frequencies pooled across the assumed species, but also ...
