Some aspects of trends and relationships in dental and medical education.

Dental education is dynamic. Many factors--economic, pedagogical, managerial, logistic, trends in disease patterns and delivery systems--are influencing its future directions and relationships with medical and other health professions' education. This article attempts to highlight those trends and relationships, at least in part of the world.

The essential role of integrative biomedical sciences in protecting and contributing to the health and well-being of our nation.

The biomedical sciences in the United States are currently experiencing the effects of an increased emphasis on in vitro models of biological and disease processes. Advances in cellular and subcellular biology have been a driving force in the funding of new research, the training of new scientists, and new drug discovery and development. The importance of new findings at the cellular and subcellular levels is not disputed. However, the corresponding decline in funding and training opportunities for biologically relevant investigations at the level of the intact animal (including humans; hereafter designated as integrative biology) is a serious threat to continued biomedical advances. The lack of resources for integrative biology has far-reaching negative consequences in 1) the development and utilization of whole animal models of disease and dysfunction; 2) assessing the relevancy of in vitro studies to physiological mechanisms; 3) the evaluation of the scientific merit of whole animal investigations and their relevancy to the nation's scientific imperatives; 4) the instruction of young scientists in the technology and especially in the methods of integrative biology, including how to develop appropriate experimental hypotheses; 5) the instruction of graduate, medical, dental, pharmacy, and nursing students in drug and disease processes in the intact human; and 6) the ability of the pharmaceutical manufacturers, the FDA, the EPA and academia to hire scientists who can develop drugs and evaluate the effects of exogenous agents on the intact animal. These negative consequences can be alleviated in a variety of ways. These include 1) increasing the availability of funding for research in integrative biology, 2) increasing the opportunities for training in integrative biology, and 3) instituting grant reviews of integrative biomedical research by peers in integrative biomedical sciences. These measures can revitalize integrative biomedical research, help ensure the continued advancement of biomedical understanding, and consequently contribute to the alleviation of human suffering.

Database access and problem solving in the basic sciences.

This study examined the potential contribution that access to a database of biomedical information may offer in support of problem-solving exercises when personal knowledge is inadequate. Thirty-six medical students were assessed over four occasions and three domains in the basic sciences: bacteriology, pharmacology, and toxicology. Each assessment consisted of a two-pass protocol in which students were first assessed for their personal knowledge of a domain with a short-answer problem set. Then, for a sample of problems they had missed, they were asked to use a database, INQUIRER, to respond to questions which they had been unable to address with their personal knowledge. Results indicate that for a domain in which the database is well-integrated in course activities, useful retrieval of information which augmented personal knowledge increased over three assessment occasions, even continuing to increase several months after course exposure and experience with the database. For all domains, even at assessments prior to course exposure, students were able to moderately extend their ability to solve problems through access to the INQUIRER database.

[Space medicine and life sciences in space].

The examination of pathophysiological disturbances and the process of adaptation in man during space flight is not for optimizing of the biological systems during the training of cosmonauts and astronauts for their stay in space only. These results are also important for medical application on patients. In real microgravity disturbances of motor performances, coordination of movements, accuracy of movements, muscle function as well as structural changes in muscles is found in real microgravity. Spinal reflexes and the control of vestibular system on eye movements are also afflicted. Higher brain functions, especially associative reactions, critical abilities, memory, as well as high brain function like space orientation, body scheme control, geometric and arithmetic analysis and its reproduction, at last speech production, writing and reading are decreased. Vegetative disorders, bone decalcification, primary muscular atrophy occur as well as changes in sleep--wake regulation and diminishing of vigility. Disturbances of blood and body fluid circulation and biologic radiation damage are further effects of man space flight. Several problems of space adaptation can be studied with the methods of the simulated microgravity using the dry water immersion, examination and the bed rest model in special laboratories. The routine medicine is learning from the scientific results of the research in real and simulated microgravity.
