A subhuman primate model for fetal alcohol syndrome research. 1981

H L Altshuler, and T S Shippenberg

The object of this project was to develop and evaluate new methods for the establishment of a subhuman primate model (SPM) of the fetal alcohol syndrome (FAS). Adult Rhesus monkeys (5.5--16.0 kg) were used as subjects. All were proven breeders and all matings in this project were repeats of matings that had previously produced normal offspring. The animals received alcohol (ALC) via permanently implanted intragastric cannulae (IGC) at doses to establish blood alcohol concentrations (BAC) within 2 selected ranges. Initially the high dose group received ALC doses designed to maintain BAC of approximately 150 mg/100 ml, and the other at 75--100 mg/100 ml. Daily ad lib food intake was monitored. The animals received infusions of liquid diet through the IGC so that their daily intake of balanced calories was 110% of the minimum daily requirements. The overall experimental design of this study called for each animal to have on ALC exposed pregnancy, serve as a pair-fed control for its own ALC exposed pregnancy and serve as a pair-fed control for a different animal. The preliminary results indicate that the IGC was suitable for use in pregnant rhesus monkeys. Two animals that were receiving ALC at doses and schedules to maintain the BAC above 150 mg/100 ml aborted during the first trimester of their pregnancies. No abortions have been observed in animals receiving either control diets or lower doses of ALC. In summary, this preliminary study demonstrates that it is feasible to use an IGC as a method for maintaining precise control over a pregnant Rhesus monkey's ALC exposure and nutritional status and thereby establish a SPM of FAS that meets critical control criteria.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D002404	Catheterization	Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.	Cannulation,Cannulations,Catheterizations
D004195	Disease Models, Animal	Naturally-occurring or experimentally-induced animal diseases with pathological processes analogous to human diseases.	Animal Disease Model,Animal Disease Models,Disease Model, Animal
D005260	Female		Females
D005333	Fetus	The unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. In humans, the unborn young from the end of the eighth week after CONCEPTION until BIRTH, as distinguished from the earlier EMBRYO, MAMMALIAN.

D000431	Ethanol	A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D063647	Fetal Alcohol Spectrum Disorders	An umbrella term used to describe a pattern of disabilities and abnormalities that result from fetal exposure to ETHANOL during pregnancy. It encompasses a phenotypic range that can vary greatly between individuals, but reliably includes one or more of the following: characteristic facial dysmorphism, FETAL GROWTH RETARDATION, central nervous system abnormalities, cognitive and/or behavioral dysfunction, BIRTH DEFECTS. The level of maternal alcohol consumption does not necessarily correlate directly with disease severity.
