|Thrombocytosis is because of presence of high platelet counts in the blood. It is a disorder in which the produces too many thrombocytes. In normal healthy human the platelet counts 150,000 and 450,000 per mm3 beyond this count over 750,000 is considered as thrombocytosis. It can also be caused blood and bone marrow disease. When it is caused by bone marrow this is called as autonomous, essential or primary thrombocytosis. Conversely, secondary thrombocytosis very rarely causes thrombotic complications. Diagnosis can be done by liver enzymes, renal function, and full blood count and erythrocyte sedimentation rate. Depending on the platelet count treatments are necessary. Aspirin at low doses are considered to be protective if it of extremely high case then hydroxyurea is more preferable. Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity.The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
