Oxytocin acetate
Based on 28 publication(s) in Google Scholar
Oxytocin (α-Hypophamine) acetate is a pleiotropic, hypothalamic peptide known for facilitating parturition, lactation, and prosocial behaviors. Oxytocin acetate can function as a stress-coping molecule with anti-inflammatory, antioxidant, and protective effects especially in the face of adversity or trauma.

Effect of OT on CGRP and c-fos expression levels. A and C show c-fos, B and D show CGRP. Immunofluorescence staining showed that the number of c-fos-positive cells per FOV and the average fluorescence intensity of CGRP were significantly increased in the NTG + vehicle group compared with the sham group. OT administration significantly reduced the expression of CGRP and c-fos, while these effects were prevented after adding L368,899. Repeated OT (Oxytocin, 20 µg/kg) treatments were quickly administered at 2 µL per nostril or the same volume of saline every two minutes using the tip of the pipette 30 min before NTG and then once daily at the same time point for 11 days.C57BL/6 mice weighing 20 ~ 30 g and 6 ~ 8 weeks of age.

OT ameliorated pain sensitization and reduced neuronal activation via OTR. Note that L-368,899 was intraperitoneally injected daily 1 h before OT treatment. The mechanical and thermal pain thresholds of the hind paw and periorbital area were assessed before each NTG injection and on day 11. B, C, D The basal mechanical pain thresholds of the hind paw (B), periorbital area (C), and the thermal pain response of the hind paw (D) were significantly increased in the NTG + OT group compared with the NTG + vehicle group.The pain threshold in the NTG + OT + L368,899 group was markedly decreased compared with the NTG + OT group.Repeated OT (Oxytocin, 20 µg/kg) treatments were quickly administered at 2 µL per nostril or the same volume of saline every two minutes using the tip of the pipette 30 min before NTG and then once daily at the same time point for 11 days.C57BL/6 mice weighing 20 ~ 30 g and 6 ~ 8 weeks of age.
