Prostate fluid is due to the fluid secreted by the prostate gland, which has a very important role in male reproductive function as well as sperm development. The test items include the following: 1. lecithin vesicles. In the prostate fluid is evenly distributed, round spherical vesicles, large one, refractive, and more in number. Normal prostate fluid contains a total of 280mg/d1 of lipids, phospholipids account for 65%, while lecithin is the main. The lecithin vesicles are almost all over the field of view, and when inflammation occurs in the prostate, macrophages phagocytose a lot of lipids, so the lecithin vesicles are significantly reduced. The number of lecithin vesicles, to some extent, reflects the lightness of prostatitis as the condition stabilizes and improves after treatment, the number of lecithin may also increase. 2, blood cells. The actual fact is that the actual actual fact is that the particular person is not a person. The normal condition of red blood cells are occasionally seen, only when inflammation, such as massage too much can cause an increase in the number of red blood cells, and even visible bleeding phenomenon. The normal prostate fluid has scattered leukocytes, no more than 10 per high magnification field of view, and scattered, not in piles and bunches. In the case of inflammation, due to the drainage of the excretory ducts uneasy pressure can be seen in heaps of pus cells or leukocytes, if observed under the microscope more than 10 to 15 leukocytes per high magnification field, it can be diagnosed as bacterial prostatitis. 3. Starch particles, stones or spermatozoa can also be seen in the prostate fluid, which is generally not introduced because it has no significant significance in the diagnosis of prostate disease. The biochemistry of the prostate fluid is very rich, meaningful for the diagnosis of prostate disease include pH, zinc, acid phosphatase, citrate and leucine aminopeptidase, etc. The content of zinc and various enzymes decreases when inflammation occurs, but it is rarely used in clinical practice. 4, protein. Prostate fluid contains very little protein, mainly containing high concentrations of zinc ions, acid phosphatase, protein hydrolase, fibrinase, spermidine, lipid polypeptides, etc.. Among them, protein hydrolase and fibrinase have the role of promoting the liquefaction of semen, while the detection of acid phosphatase and citric acid can help determine the function of the prostate and the presence of cancer.
