The alveolar bone of the marmoset is exceedingly vulnerable to the resorption induced by excessive amounts of parathyroid hormone. Inclusion of 50 ppm fluoride in the drinking water of the marmosets for five months resulted in a histologically measurable degree of protection against the bone-destroying proclivity of the hormone.
Marmosets, Saguinus oedipus oedipus and S . fuscicollis, have been shown to have a diurnal heart rate pattern that has a marked difference between high and low values (about 55 beats/minute) and shows a low point during daylight hours around 1300-1400 hours. A similar pattern for body temperature was seen. A species difference existed; the larger S. 0. oedipus has a higher heart rate during both light and dark periods. All measurements were made on undisturbed animals at hourly intervals using radiotelemetry. They were kept in a controlled environment with a light cycle of 12L: 12D and a temperature of 27 * 1°C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
