Hemostatic effect
Bursic acid has a hemostatic effect in leeks. Leek extract (including oxalic acid) is intravenously or intramuscularly injected (2-3 ml each time, every 2 to 4 hours, with a maximum of 15 ml per day) in various bleeding patients, with significant hemostasis. In hemophilia patients, clot resistance can be increased. A small amount of 0.02g/10g body weight of the mice was administrated with amaranth decoction. The hemorrhage time was shortened in more than half of the mice, and the larger amount (approximately 0.06g/10g body weight of crude drug) extended the bleeding time of most mice. ; The use of liquid extract volatile liquid to intraperitoneal injection of mice, have a role in shortening the bleeding time (a large amount of more significant). Rabbit intravenous injection of volatile liquid extract can shorten clotting time. However, there are also opposite reports. The leek grown in hot climate and dry soil of Samar Khan was made into 10% immersion liquid. Subcutaneous injection in rats caused significant prolongation of hemagglutination time and caused bleeding instead. 10% leek extract 0.1ml, no effect on rabbit clotting.
Effect on heart and blood vessels
The alcohol extracts of leeks can be given intravenously to dogs, cats, rabbits, and rats. This may cause a transient decrease in blood pressure, which is not antagonized by 80 μg/kg atropine. The whole plant active ingredients can also cause rats, cats, dogs, dogs to have a transient blood pressure drop, can not be antagonized by atropine, but can be inhibited by Prone-thanol; no change in electrocardiogram, on the dog heart and the heart of the guinea pig Coronary vessels have an expanding effect. It also inhibits fibrillation of isolated cat hearts caused by ouabain. Intravenous injection of leek extract in rabbits can reduce blood pressure, but it cannot reverse the effects of adrenaline. Leek decoction or liquid extract volatile liquid, a brief antihypertensive effect on anesthetized dogs, if the first use of atropine to fight the decline in blood pressure. Intravenous injection of dried leek soaked can quickly lower the blood pressure of the dog to 40-50% of its original level. It can also lower blood pressure in chickens. The frogs had no effect on the vascular irrigation of the lower extremity leeches alcohol extract (20%-0.5ml); dried leek infusion, the high concentration (10%) caused the vasoconstriction, and the low concentration (2% or less) expanded the blood vessels. Alcohol extracts have an expanding effect on the blood vessels of the lower extremities of dogs. It was previously thought that its antihypertensive effect was related to choline and acetylcholine contained, but no such two substances were found in the chives alcohol extract and a quaternary ammonium compound different from acetylcholine was found.
The role of the uterus
Leeks have a similar role to ergot. Its extracts were tested in isolated uteri or intestine of animals and both showed significant contraction. The whole grass alcohol extract has oxytocin-like uterine contraction. The whole plant active ingredients can make mice and rats contract from the uterus. In isolated rat uterus (unpregnancy), rabbits in the uterus (pregnancy and non-pregnant), cats in the body uterus (not pregnant) can strengthen its contraction. With a relatively crude drug of 0.08-0.8g/kg intravenously in the uterine sacrum rabbit, visible uterine contraction, muscle tone and frequency increased slightly; decoction gavage (a considerable amount of crude drug 5.263g/kg) is also the case. Excitable uterus active ingredient, soluble in water and aqueous alcohol, insoluble or extremely difficult to dissolve in pure alcohol, petroleum ether, anhydrous ether or anhydrous chloroform. Leek extract also has a strong effect on uncopied guinea pig uteri (similar to fresh juice and dried medicine).
Other effects
Leek extract can extend the sleep time of barbital. Anesthetized dogs intravenous injection of leeks decoction or liquid extract volatiles, are excited to breathe; first use atropine can not affect this effect. It has also been reported that dried leek infusion can reduce the respiratory movements of dogs to 20-50% of the original level, sometimes even worse. The active ingredients of leeks and wholegrass can shrink the trachea and intestinal smooth muscle. Atropine was used to slightly inhibit the small intestine of guinea pigs, and then the chives extract was used to shrink the intestine and then restore the original state. In addition, the intraperitoneal injection of Chinese chive alcohol extract can inhibit dextran, parsley gelatinous edema, and 5-hydroxytryptamine-induced capillary permeability in rat lower limbs; 90% inhibition of Shay ulcers, and can accelerate The healing of stress ulcers. Diuretic effect on mice. Rabbits with artificial fever have a slight antipyretic effect on leeks.
Clinical application
1. Prevention of measles: 2 kilograms of whole leeks, 2 pounds of water, and 1 kilogram of fry. Once a week, each serving 100ml, prevention of medication 150, 7 patients; control group of 130 people, 56 patients.
