Abstract
Background: Ketamine is a widely used anesthetic agent. Although the potential adverse
effects of ketamine use in juvenile age are uncertain, certain studies reported that children exposed to
recurrent anesthesia could face an increased risk of neurodevelopmental deficits in motor function and
behavioral risks. We aimed to investigate the long-term effects of repeated exposure to various ketamine
doses on anxious behavior and locomotor activity in juvenile rats.
Objective: We aimed to investigate the long-term effects of repeated exposure to various ketamine
doses on anxious behavior and locomotor activity in juvenile rats.
Methods: Thirty-two Wistar Albino juvenile male rats were randomized into 5 mg/kg, 20 mg/kg, and
50 mg/kg ketamine (KET) and saline (Group C) Groups and KET was administered for 3 consecutive
days at 3-hour intervals in 3 doses. Ten days after the last KET dose, behavioral parameters were analyzed
with an open field test (OFT), elevated plus maze (EPM), and light-dark box (LDB). Satistical
analysis was conducted with Kruskall-Wallis test followed by Dunn's Multiple Comparison Test.
Results: Unsupported rearing behavior decreased in 50 mg/kg KET Groups when compared to Group
C. Incorrect transition time, total grooming time, and transfer latency time increased significantly in
the 50 mg/kg KET Group when compared to Group C.
Conclusion: These results suggested that 50 mg/kg KET led to anxiety-like behavior and destroyed
memory and spatial navigation. Ketamine doses were associated with late effects of ketamine on anxiety-
like behavior in juvenile rats. Further studies are needed to determine the mechanisms that play a
role in the different effects of ketamine doses on anxiety and memory.
期刊介绍:
Current Alzheimer Research publishes peer-reviewed frontier review, research, drug clinical trial studies and letter articles on all areas of Alzheimer’s disease. This multidisciplinary journal will help in understanding the neurobiology, genetics, pathogenesis, and treatment strategies of Alzheimer’s disease. The journal publishes objective reviews written by experts and leaders actively engaged in research using cellular, molecular, and animal models. The journal also covers original articles on recent research in fast emerging areas of molecular diagnostics, brain imaging, drug development and discovery, and clinical aspects of Alzheimer’s disease. Manuscripts are encouraged that relate to the synergistic mechanism of Alzheimer''s disease with other dementia and neurodegenerative disorders. Book reviews, meeting reports and letters-to-the-editor are also published. The journal is essential reading for researchers, educators and physicians with interest in age-related dementia and Alzheimer’s disease. Current Alzheimer Research provides a comprehensive ''bird''s-eye view'' of the current state of Alzheimer''s research for neuroscientists, clinicians, health science planners, granting, caregivers and families of this devastating disease.
