electron microscopic studies on the endometrium of the grey seal (halichoerus grypus) during its preparation for nidation.the uterine luminal and glandular epithelia of two mature grey seals, a species with obligate delayed implantation, have been examined. earlier studies of their corpora lutea had suggested that these females were in the pre-nidatory condition. ultrastructural features of these epithelia in the animal which possessed the more mature corpus luteum indicated that the luminal epithelium had attained a state of differentiation similar to that of the pre-attachment phase in the laboratory rat, a state ...1979226508
microcoulometric determination of total organochlorine pesticide and polychlorinated biphenyl residues in grey seal (halichoerus grypus) blubber. 1977402089
a study of the effects of methyl mercury, cadmium, arsenic, selenium, and a pcb, (aroclor 1254) on adrenal and testicular steroidogeneses in vitro, by the gray seal halichoerus grypus.an in vitro study on the effects of the contaminants polychlorinated biphenyl (aroclor 1254) (pcb), methyl mercury (mehg), arsenic (as), cadmium (cd), and selenium (se) on the biosynthesis of steroid hormones in the gray seal (halichoerus grypus) indicated altered steroid biosynthesis. biotransformed delta4-androstene-3, 17-dione (delta 4a), dehydroepiandrosterone, 11-ketotestosterone (11-kt), and testosterone (t) were detected in all seal testicular incubates. yields of 11-kt were greatly incre ...1977405933

myocardial blood flow in the diving seal.grey seals exhibit a marked drop in heart rate, a slight decrease in ventricular contractility, and an essentially unchanged stroke volume upon diving. in the present study, we have demonstrated that the resulting drop in cardiac output is associated with a 90% reduction of coronary blood flow. such reduction of myocardial blood flow takes place despite a significant increase in effective coronary driving pressure, and is indicative of a 800% increase in coronary vascular resistance. this means ...19761258673
sleep and cardiac rhythm in the gray seal.telemetric studies of electroencephalograms, electrocardiograms, and electroculograms and concurrent observations of behavior revealed that seals can sleep underwater, on the surface, or while hauled out. rapid eye movement preceded slow wave sleep and was accompanied by increased respiratory rate and rhythmic tachycardia. while slow wave sleep occurred under all sleep conditions, rapid eye movement occurred only when a seal was hanging at the water surface or hauled out, never underwater.1975163484

cell cultures from marine mammals.cell cultures grown from the gray seal halichoerus grypus and the dolphin lagenorhynchus obliquidens support the replication of several human viruses. further evidence indicates the gray seal kidney cell culture has transformed.197016512163

underwater sounds of pinnipeds.descriptions and analyses are presented of underwater sounds made by six species of seals in captivity, zalophus californianus, phoca vitulina, p. (pusa) hispida, p. (pagophilus) groenlandica, halichoerus grypus, and cystophora cristata. the suitability of these very faint sounds for echolocation is discussed.196317742884
