Odors from amniotic fluid produce signs of calmness in mammals suggesting some anxiolytic-like properties. Experimental models, such as the defensive burying, elevated plus maze, and open field tests offer well-controlled approaches to the study of putative anxiolytic substances using rats. Using gas chromatography-mass spectrometry, we first identified(More)
Allopregnanolone is a 5α-reduced metabolite of progesterone with actions on γ-aminobutyric acid-A (GABAA) receptors that produce antidepressant-like effects. However, little is known about the target brain regions that mediate its antidepressant-like effects. In this study, allopregnanolone (2.0 μg/0.3 μl/rat) or its vehicle (35% cyclodextrin solution) were(More)
A mixture of eight fatty acids (linoleic, palmitic, stearic, myristic, elaidic, lauric, oleic, and palmitoleic acids) at similar concentrations identified in human amniotic fluid produces anxiolytic-like effects comparable to diazepam in Wistar rats. However, individual effects of each fatty acid remain unexplored. In Wistar rats, we evaluated the separate(More)
Human amniotic fluid and a mixture of eight fatty acids (FAT-M) identified in this maternal fluid (C12:0, lauric acid, 0.9 μ g%; C14:0, myristic acid, 6.9 μ g%; C16:0, palmitic acid, 35.3 μ g%; C16:1, palmitoleic acid, 16.4 μ g%; C18:0, stearic acid, 8.5 μ g%; C18:1 cis, oleic acid, 18.4 μ g%; C18:1 trans, elaidic acid, 3.5 μ g%; C18:2, linoleic acid, 10.1(More)
Eight fatty acids (C12-C18) were previously identified in human amniotic fluid, colostrum, and milk in similar proportions but different amounts. Amniotic fluid is well known to be the natural environment for development in mammals. Interestingly, amniotic fluid and an artificial mixture of fatty acids contained in amniotic fluid produce similar(More)
