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.
Cute things often come in small packages, and the corgi is no exception. There are two kinds of corgis: the Cardigan Welsh and the Pembroke Welsh. The biggest physical difference between them is that the Cardigan has a tail, whereas the Pembroke has a little stump or no tail at all. Both types of corgis are mini low-riders with long, sturdy bodies set atop short, little legs. Corgis are medium-sized dogs weighing between 25 and 35 pounds and reaching a maximum height of 12 inches.
