If you have tissue eosinophilia, the level of eosinophils in your bloodstream is likely normal. Blood eosinophilia may be detected with a blood test, usually as part of a complete blood count. A count of more than 500 eosinophils per microliter of blood is generally considered eosinophilia in adults. A count of more than 1,500 eosinophils per microliter of blood that lasts for several months is called hypereosinophilic syndrome. Causes.
Preheat the oven to 400 degrees F (204 degrees C). Place the short ribs on a baking sheet, season with salt and pepper, and roast in the oven for 15 minutes. Remove the ribs from the oven, and then reduce oven temperature to 300 degrees F (149 degrees C).
When cooked in a low-temperature oven --250 degrees-- pork ribs take about 4 hours. When using this method, apply a dry rub to the ribs, and cook, uncovered, for 2 hours. Then baste them with barbecue sauce, cover the pan with foil and roast for about 2 more hours. The ribs are finished when the meat starts to pull away from the bone.
