Irradiated blood products are used to prevent graft-vs-host disease in patients at risk. Many attempts have been made to develop blood substitutes using inert chemicals (eg, perfluorocarbons) or Hb solutions to carry and deliver oxygen to tissues.
Temperament. The Pembroke Welsh Corgi is highly intelligent, loyal, able and willing to please its owner. Corgis are extremely active and are good with children so long as the dog sees humans as above him in the pack order. Protective and sturdy, they make fine guards, and excellent show and obedience dogs.
The Corgi breed does shed, however, a light brushing twice a week for 20 minutes and a high-quality dog food will keep the shedding to a minimum. Adult Corgi's can adjust and adapt to a new home with minimal problems as long as the owners are dog-savvy and have done their research on the breed.
