Long-Term Effects Of Early Social Isolation In Macaca Mulatta: Changes In Dopamine Receptor Function Following Apomorphine Challenge, Mark H. Lewis, John P. Gluck, Tom L. Beauchamp, Michael F. Keresztury, Richard B. Mailman
John P. Gluck, PhD
The hypothesis that early social isolation results in long-term alterations in dopamine receptor sensitivity was tested using older adult rhesus monkeys. Isolated and control monkeys were challenged with apomorphine (0.1 and 0.3 mg/kg), and the drug effects on spontaneous blink rate, stereotyped behavior, and self-injurious behavior were quantified using observational measures. Monoamine metabolites were quantified from cisternal CSF by HPLC-EC, prior to pharmacological challenge. Isolated and control monkeys did not differ in CSF concentrations of HVA, 5-HIAA, or MHPG. At the higher dose, apomorphine significantly increased the rate of blinking, the occurrence of whole-body stereotypies, and the intensity of stereotyped …
Ethical Issues In The Use Of Animals In Biomedical And Psychopharmocological Research, John P. Gluck, Jordan Bell
Ethical Issues In The Use Of Animals In Biomedical And Psychopharmocological Research, John P. Gluck, Jordan Bell
John P. Gluck, PhD
Rationale: The ethical debate concerning the use of animals in biomedical and pharmacological research continues to be replete with misunderstandings about whether animals have moral standing. Objectives: This article briefly reviews the central ethical positions and their relationship to the basic parameters of research regulation from an international perspective. The issues associated with the validation of animal models will then be discussed. Finally, suggestions for empirical ethics research will be presented. Methods: Recent literature reviews were accessed and analyzed. Results: This review summarizes the pertinent ethical and research literature. Conclusions: In summary, regardless of the ethical perspective one favors, there …
Harry F. Harlow And Animal Research: Reflection On The Ethical Paradox, John P. Gluck
Harry F. Harlow And Animal Research: Reflection On The Ethical Paradox, John P. Gluck
John P. Gluck, PhD
With respect to the ethical debate about the treatment of animals in biomedical and behavioral research, Harry F. Harlow represents a paradox. On the one hand, his work on monkey cognition and social development fostered a view of the animals as having rich subjective lives filled with intention and emotion. On the other, he has been criticized for the conduct of research that seemed to ignore the ethical implications of his own discoveries. The basis of this contradiction is discussed and propositions for current research practice are presented.
Moving Beyond The Welfare Standard Of Psychological Well-Being For Nonhuman Primates: The Case Of Chimpanzees, John P. Gluck
Moving Beyond The Welfare Standard Of Psychological Well-Being For Nonhuman Primates: The Case Of Chimpanzees, John P. Gluck
John P. Gluck, PhD
Since 1985, the US Animal Welfare Act and Public Health Service policy have required that researchers using nonhuman primates in biomedical and behavioral research develop a plan ‘‘for a physical environment adequate to promote the psychological well-being of primates.’’ In pursuing this charge, housing attributes such as social companionship, opportunities to express species-typical behavior, suitable space for expanded locomotor activity, and nonstressful relationships with laboratory personnel are dimensions that have dominated the discussion. Regulators were careful not to direct a specific set of prescriptions (i.e., engineering standards) for the attainment of these goals, but to leave the design of the …
Social Deprivation Of Infant Rhesus Monkeys Alters The Chemoarchitecture Of The Brain: I. Subcortical Regions, Lee J. Martin, Dawn M. Spicer, Mark H. Lewis, John P. Gluck, Linda C. Cork
Social Deprivation Of Infant Rhesus Monkeys Alters The Chemoarchitecture Of The Brain: I. Subcortical Regions, Lee J. Martin, Dawn M. Spicer, Mark H. Lewis, John P. Gluck, Linda C. Cork
John P. Gluck, PhD
Rhesus monkeys (Macaca mulatta) reared during the first year of life without social contact develop persistent stereotyped movements, self-directed behaviors, and psychosocial abnormalities, but neurobiological mechanisms underlying the behaviors of socially deprived (SD) monkeys are unknown. Monkeys were reared in total social deprivation for the first 9 months of life; control monkeys were reared socially (SR) with mothers and peers. Subjects were killed at 19-24 yr of age. Because the behaviors of SD monkeys are reminiscent of changes in striatal or amygdalar function, we used immunocytochemistry for substance P (SP), leutine-enkephalin (LENK), somatostatin, calbindin, and tyrosine hydroxylase (TH) to evaluate …
