... (EPM), and a forced swimming test (FST). Sera and hippocampi were obtained from the rats, and an enzyme-linked immune sorbent assay was performed to determine corticosterone concentration. Western blotting was conducted to determine BDNF, tyrosine kinase receptor B (TrkB), cAMP-response element-binding...

... of depression induced by corticosterone (CORT). The involvement of neuroprotective and antioxidant mechanisms in the generation of this effect was also assessed. Methods: Female mice were submitted to CORT for 21 days and treated with RIP I in the last 7 days. Behavioral and neurochemical analyses were...

... compared the impact of massive MOR dysregulation on 3 behavioral aspects of behavior and on serotonin, BDNF, and corticosterone levels. Methods: The study used 24 female white Wistar rats which were randomly divided into (1) control group: pregnant rats without any intervention; (2) opium-exposed group...

... and Hsp70. In Wistar rats, chronic social isolation leads to a significant decrease in serum corticosterone (CORT), probably due to alterations in the GR signaling pathway. We exploited this type of stress, alone or in combination with acute immobilization, to define changes in the expression level...

... in reactivity of the corticotropic axis: HR rats exposed to a novel environment have a prolonged secretion of corticosterone compared to LR rats. The association of novelty, drug and food seeking in the same individual suggests that these characteristics share common processes. Differences in dopaminergic...

...-HT), and 5-hydroxyindoleacetic acid (5-HIAA) using high-performance liquid chromatography with electrochemical detection. Trunk blood was analyzed for serum levels of testosterone (T), luteinizing hormone (LH) and corticosterone (C), and weights of testes and epididymides were recorded. Both activity...

... are controversial. In the present study, we analyzed the levels of corticosterone and testosterone in rats neonatally treated with CMI in response to chronic stress by repeated immersion in cold water. Results obtained in the forced swim test corroborated the effect of neonatal CMI administration, showing...
