Cutaneous anaphylactoid reaction to polyoxyethylene hydrogenated castor oil in dogs.

Background: Polyoxyethylene hydrogenated castor oil (HCO ethoxylates) is a nonionic surfactant used as an excipient for ointments and injections in human and veterinary drugs. Several polyethylene glycol (PEG) derivatives can be obtained depending on the number of moles of ethylene oxide (EO). HCO ethoxylates have the potential to cause anaphylactoid reactions.

Relationships between the expression of adipose genes and profiles of hospitalized dogs.

Obesity is one of the risk factors for the onset of various metabolic diseases in dogs. Energy expenditure in brown/beige adipocytes, which is partially regulated by the bone morphogenetic protein (BMP) pathway, is a key factor determining systemic energy balance. Here, we examined gene expression in the fat depots of 129 hospitalized dogs, and the relationship between the relative levels of gene expression and profiles of dogs.
