1.Fixed mouse left-handed, so to catch mice in the stomach for the supporters, mouse head slightly down. Syringe from the right hand side of the lower abdomen to puncture, the needle piercing the skin and abdominal muscles appear before 45 degrees, the needle piercing the skin of about 3-5mm needle backward, When you feel a sense of frustration that has entered the abdominal cavity, Withdrawing without blood, intestinal fluid, urine, immediately after injection. Injection volume of 0.1 ~ 0.2ml/10g weight. In this study, to practice operations with normal saline.
2.After the capture of mice fixed (as above), right hand holding device by gavage stomach tube into the mouth to mouth. Gently press with a stomach tube on the palate in mice, so that the mouth and esophagus in a straight line, and then slowly fed into the tube along the esophagus on the palate, about 2-3cm needle injection can be (note). Infusion volume of 0.1 ~ 0.3ml/10g weight. In this study, carried out with 5% charcoal suspension stomach operation, it can be fed successfully anatomical observation.
3.Approach is correct, the needle is smooth and no abnormal breathing animals; such as needle met with resistance, should be out again, not strong interpolation. So as not to puncture the esophagus or strayed into the trachea, the animals died.
4.Injection, mice were first fixed in a fixed inside (the end of a small population can be tube glass tube, metal or wire cage), exposed to all the tail out so clearly after tail vein filling to the end of the left thumb and forefinger on both sides, right hand holding the syringe needle 4, piercing the vein was 30 degrees, injection is successful, pull out the needle, touch the injection site to stop bleeding. An injection volume of 0.05-0.1 ml/10g.
5.Liquid injection without resistance, and visible veins occur along a white line, indicating that needle in the blood vessels can continue to inject drugs. In case of resistance to large, pale skin and a raised, indicating the intravenous needle is not required to pull out the needle to re-puncture.
6.End of tail flick with your fingers if necessary, and the tail immersed in warm water 45-50 ℃ with 75% alcohol or xylene rubbed the mice were placed in the rear or 40-50 ℃ heating plate for movement through the above method, you can make All vascular dilatation and congestion in mice, skin softening skin, easy to puncture. General choice of the end of both sides of the vein, and should start from the tail tip, moving gradually to the tail root to prepare for repeated applications.
7.Kunming mice: introduction from India in 1946, Kunming, size small; calving and more rapid growth and reproduction, breeding management, and convenient; on the environment adaptability and strong resistance to disease; is widely used in pharmacology, toxicology, viral , Microorganisms and the biological products, pharmaceutical identification, is commonly used in experimental animals.
