A study was made of excitatory and inhibitory responses elicited by acetylcholine (ACh) in neurons of the snail Eobania vermiculata. At resting potential, ACh evoked a depolarizing inward current in some neurons (D-cells) and a hyperpolarizing current in others (H-cells). The currents elicited by ACh were nonlinearly dependent on membrane potential. After either D- or H-cells were equilibrated ...

Suaeda asparagoides (Miq.) has long been used as a Korean folk herbal medicine for the treatment of functional gastrointestinal disorders. However, reports on its pharmacological activity on gastrointestinal motility are scarce. The present study investigated the effects of Suaeda asparagoides water fraction of the extract (SAWF) on antral motility in vitro. Muscle strips from rat gastric antru...

Ž . We determined the feasibility of using salt-tolerant plants halophytes as biofilters to remove nutrients from saline aquaculture wastewater. Suaeda esteroa, Salicornia bigeloÕii and Atriplex Ž . barclayana Chenopodiaceae , species with potential as forage and oil seed crops, were grown in Ž . sand in draining containers lysimeters in a greenhouse experiment. They were irrigated to meet evap...

Flow hindrance by salt-marsh vegetation is manifested in the structure of the tidal current; it has a significant impact on sediment transport and causes increased sediment accretion. The flow characteristics in 3 different vegetation types (Spartina maritima, Sp. anglica and Salicornia/Suaeda maritima) were measured on 3 salt-marshes in Portugal and England. Skimming flow develops above the Sp...

seed proteins of eight species of the genus suaeda (chenopodiaceae) were compared by means of polyacrylamide disc gel electrophoresis. different samples of the same species showed not less than 89% similarities, and geographical separation had no remarkable effect on seed protein patterns of the same species. morphological heterogenity, that creates difficulties in infrageneric classification, ...

Suaeda salsa is a leaf-succulent euhalophytic plant capable of surviving under seawater salinity. Here, we report the isolation and functional analysis of a novel Suaeda gene (designated as SsTypA1) encoding a member of the TypA/BipA GTPase gene family. The steady-state transcript level of SsTypA1 in S. salsa was up-regulated in response to various external stressors. Expression of SsTypA1 was ...
