neutrophil nucleus drumstick body

Drumstick body, at one end of the mature neutrophil (rod or lobulated) nucleus (or other part), there is a protrusion with a diameter of 2 ~ 4μm outward, the head (top) ellipse or more The hammer is shaped, hence the name. A cell usually contains one, sometimes two, and the stain is consistent with the nucleus. Some people use this to identify men and women. In normal adults, neutrophils contain sex chromosomes, women account for about 5%, and men generally have less than 1%. In patients with cancer or radiation sickness, this small body increases and there is no gender difference. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: After taking blood, you need to press it at the pinhole for 3-5 minutes to stop bleeding. Normal value Male <1%, female>1.5%. Clinical significance Identification of hermaphroditism and sex chromosome abnormalities. Precautions The classification of white blood cells is greatly changed by factors such as technical factors and cell distribution factors, so the dispersion of classification counts is large, and the proportion of neutrophils and lymphocytes, which account for a large proportion in the classification, is normally distributed, accounting for a small proportion. Such as eosinophils, basophils and monocytes are Powson distribution. Inspection process (1) Take a small drop of blood on one end of the slide, and use a push piece to push the circumference around 35 ° ~ 45 ° to leave a proper amount of voids, which can distinguish the thin blood of the head, body and tail. The length of the blood film is not less than 2.5 cm, and the remaining space to the other end of the slide is about 1 cm. The blood film is dried and stained. (2) Wright's Giemsa composite staining method: flat blood sample on the staining rack, add 3 to 5 drops of staining solution, immediately cover the blood film, add about 5 to 10 drops of buffer after about 30s, gently shake the glass The tablets or lightly blow the mixture to mix the dye solution with the buffer solution. After 5 to 10 minutes, the dye solution is washed away with water and dried for microscopic examination. (3) Rapid method: place the rapid dyeing liquid A and liquid B in the appropriate size dyeing tank, immerse the blood film in the liquid for 30s, wash it, then immerse it in the liquid for 30s, wash it, and dry it for microscopic examination. (4) Microscopic examination: Select the junction of the meninges and tails, and the red blood cells have not overlapped with oil mirrors. The examination should have a certain direction from top to bottom and left and right, and take into account the edges of both sides of the long film of the blood film, otherwise it will affect various cells. Detection rate. Count 100 to 200 white blood cells, classify them according to their morphology, and find the percentage. Not suitable for the crowd Have a coagulopathy such as hemophilia. Adverse reactions and risks Discomfort: There may be pain, swelling, tenderness, and visible subcutaneous ecchymosis at the puncture site.
