The gram stain shown here demonstrates many neutrophilic leukocytes, one of which contains gram negative intracellular diplococci indicative of Neisseria gonorrheae infection.
Bacterial growth and death of alveolar macrophages produce powerful chemotactic factors that cause a large influx of polymorphonuclear leukocytes and monocytes from the peripheral blood.
Leukocytes show very prominent nuclei when stained. They total about 5,000 to 10,000 per cubic millimeter, but their number may increase during infection.
Leukocytes protect us against foreign substances. Some engulf foreign material by the process of phagocytosis;others function as part of the immune system.
There are five different types of leukocytes: three types of granulocytes (eosinophil, basophil, and neutrophil) and two types of agranulocytes (monocyte and lymphocyte).
This inflammation and local pain's ultimately caused by white blood cells, or leukocytes, which migrate to the site to help eliminate uric acid and release proinflammatory chemicals, including cytokines.
The first T cell lymphoma is adult T-cell lymphoma, but it's sometimes referred to as a leukemia because the abnormal white blood cells or leukocytes often get into the bloodstream.
Then you've got this thin little whitish layer in the middle. Those are your warriors, the leukocytes or white blood cells, that defend your body from toxins and foreign microbes.
You've also got larger, infection-fighting white blood cells, or leukocytes in the mix, and your platelets, the small cell fragments needed for blood clotting so that a paper cut doesn't bleed you dry.
They would need to have a close enough human leukocyte antigen or HLA match to maximise the chances the transplant would work - as well as the rare genetic abnormality conferring HIV resistance.
们需要有足够接近的人类白细抗原或 HLA 匹配,以最大限度地提高移植成功的机会——以及罕见的遗传异常导致 HIV 耐药。

Virchow was the first to explain that cancer develops from cell abnormalities, and he described and named leukemia, a potentially fatal disease in which the blood produces too many leukocytes, white blood cells.
