The problem is that most of the heat transfer in an oven is radiant, so a transparent liquid in a transparent dish is going to get very little heat transfer. Though the air is transparent as well, it need much less heat to get to temperature than water does. One option is to use a non-transparent dish.
The emergency treatment of polycythemia (e.g., in hyperviscosity or thrombosis) is by venesection, the removal of blood from the circulation. Depending on the underlying cause, venesection may also be used on a regular basis to reduce the red blood cell count.
For instance, we see that the prefix 'poly' means many, the word 'cyt' refers to cells and the suffix 'emia' refers to in the blood. So polycythemia is literally 'many cells in the blood.' Types: Polycythemia Vera. There are two types of polycythemia. The first is called polycythemia vera, which is also known as primary polycythemia. Polycythemia vera is caused by a problem with the bone marrow, resulting in an overproduction of cells. The bone marrow is the 'primary' site for red blood cell production, which might help you recall this term's alternate name.
