Using a Java Dynamic Tree to manage the terminology in a suite of medical applications.

Objectives: Now that the National Library of Medicine has made SNOMED-CT widely available, we are trying to manage the terminology of a whole suite of medical applications and map our terminology into that in SNOMED.

Methods: This paper describes the design and implementation of the Java Dynamic Tree that provides structure to our medical terminology and explains how it functions as the core of our system.

Results: The tree was designed to reflect the stages in a patient interview, so it contains components for identifying the patient and the provider, a large set of chief complaints, review of systems, physical examination, several history modules, medications, laboratory tests, imaging, and special procedures.

An empirical study of the Health Status Questionnaire System for use in patient-computer interaction.

Patient involvement in the health care process is very important to any attempt to improve health care quality and patient satisfaction. Although many computerized medical record systems have been introduced, physicians are the only players in the process of data collection and interpretation. A computerized version of the Health Status Questionnaire has been developed to provide a simple, inexpensive method of direct patient entry into the medical record.

Estradiol interacts with gastric or postgastric food stimuli to decrease sucrose ingestion in ovariectomized rats.

The sham feeding preparation was used to determine whether systemic estradiol administration inhibits the intake of 0.8 M sucrose of ovariectomized rats by decreasing the potency of pregastric controls of ingestion. During real feeding, significant reductions in the sucrose intake of estradiol-treated rats appeared within 5-6 min.

Cyclic estradiol replacement increases the satiety effect of CCK-8 in ovariectomized rats.

The influence of cyclic ovarian hormone replacement therapy on the satiety effect of exogenous CCK-8 was determined to investigate the mechanism mediating the preestrous decrease in meal size in female rats. Once weekly, food-deprived ovariectomized rats were IP injected with 0.5-4 micrograms/kg CCK-8 and offered 0.
