Cadmium and copper metallothioneins in the American lobster, Homarus americanus.
Lobsters were fed cadmium-rich oysters for 28 days, and the induction of cadmium metallothionein and its relation to concentrations of cadmium, copper, and zinc in the digestive gland and gills was determined. A portion of the tissues also was retained for determining the cytosolic distribution of these metals by gel filtration and ion-exchange chromatography. The digestive gland contained a ma...
متن کاملEffects of epizootic shell disease in American lobster Homarus americanus determined using a quantitative disease index.
The incidence of epizootic shell disease in American lobster Homarus americanus has increased in southern New England, U.S.A., in the last decade, but few longitudinal studies have followed the disease progress in individual lobsters or demonstrated direct effects on mortality or growth. Diseased lobsters were held in the laboratory for 1 yr, and the progression of disease and its effects on mo...
متن کاملGross Dissection of the Stomach of the Lobster, Homarus Americanus
The stomach of the American lobster (Homarus americanus) is located in the cephalothorax, between the rostrum and the cervical groove. The anterior end of the stomach is defined by the mouth opening and the posterior end by the bottom of the pylorus. Along the dorsal side of the stomach lies the stomatogastric nervous system (STNS). This nervous system, which contains rhythmic networks that und...
متن کاملNeural activation of the heart of the lobster Homarus americanus.
INTRODUCTION The heart-ganglion preparation of the lobster is an independent nerve-effector system. It can be isolated from the rest of the animal and maintained for many hours, actively contracting, in a cooled saline bath. It is therefore an ideal system for studying the functional organization of a relatively simple organ a pump that is governed by a part of the nervous system composed of on...
متن کاملTemperature dependence of cardiac performance in the lobster Homarus americanus.
The lobster Homarus americanus inhabits ocean waters that vary in temperature over a 25 degrees C range, depending on the season and water depth. To investigate whether the lobster heart functions effectively over a wide range of temperatures we examine the temperature dependence of cardiac performance of isolated lobster hearts in vitro. In addition, we examined whether modulation of the heart...
