Elective test jus over! woohoo! 1 paper down.. Still got so many more to go.. Sigh.. School is getting boring. When was it interesting? Mayb the first few days of school when there are so much to explore. Now that u noe the school inside out, u dun haf much things to do except for visiting the lib, eplaza, com lab n canteens. Sooner or later, I'll b sick of those places. In fact, i'm kinda sick of it now.

Now in bio studying on blood disorders. Coincide with Rev Denis Shelton's illness. Esther told me it's myeloma. In elective we studied that "mye-" got to do with bone marrow. We did an ICA presentation on Chronic Myeloid Leukemia a few weeks back. And it's got to do with myeloma too. Hmm.. Found this on yahoo... "Myeloma results from an acquired injury to the DNA of a single cell in the lymphocyte development sequence that leads to the formation of plasma cells. Myeloma occurs in lymphocytes developing into B cells, as opposed to T cells. B lymphocytes transform into plasma cells, which produce proteins called antibodies."

"Myeloma is a cancer of plasma cells. Plasma cells, part of the body's immune system, are one type of white blood cells. They are found primarily in bone marrow but also in many other tissues of the body. Normal plasma cells are formed from B lymphocytes. In myeloma, a developing plasma cell becomes malignant. The number of myeloma cells increases, especially in the marrow, crowding out normal blood cell production, destroying normal bone tissue and causing pain.
Myeloma interferes with normal plasma cell production of proteins called immunoglobulins or antibodies. Immunoglobulins (antibodies) are an important part of the body's natural defense against infection. They recognize and destroy microbes that invade the body. Myeloma cells produce an abnormal immunoglobulin called M protein, for monoclonal immunoglobulin, which does not function and makes myeloma patients susceptible to infections.
The cause of myeloma is not known."

I find leukemia interesting. I was the one who choose CML for ICA too. Well, probably watched to much Korean VCDs.. Most of them ends with the main character suffering from Leukaemia.

In bio we studied about bone marrow. As bone marrow is the site of blood production. It in contains stem cells which further divides into myeloids n lymphoids. Myeloids stem cells-> proerythroblasts-> erythroblasts-> reticulocytes-> erythroctyes. (production of RBCs).

In skills lab, we observed Mr Roger doing a bone marrow biopsy. Gosh.. I pity those who have to go thru this procedure. It's extremely pain and sometimes the pain is unbearable. Ouch.
Got pricked ytd for blood glucose monitoring. It still hurts though. Imagine diabetic patients have to go thru them almost everyday... Mine is uncomparable..
