The animal form is also a chain snake
The body length can reach 1.2 meters. The head is slightly flat and oval. The snout scales are high and can be seen from the back. The scale between the nose is small and the front end is oval. Frontal scale is short, and its length is about equal to the distance from its front edge to the front edge of nasal scale. Cranial parietal scales are long and large, and the length is the sum of frontal scales and forehead scales. The scales on the eyes are small. The buccal scales are long and narrow, and the lower part is connected with the second and third upper lip scales. 8 pieces of upper lip scales. The scales in front of the eyes are small, 1 piece, not reaching the head and back; There are 2 posterior scales, even 3. There are 2 anterior temporal scales, and the lower one is extra large; 3 pieces of posterior temporal scales. The nostril is located between the two nasal scales and has a valve. There are 1 scales of the lower lip, and the anterior chin scale is larger than the posterior chin scale, which is connected with the first four scales of the lower lip. There are two pairs of small scales between the posterior mental scale and the first abdominal scale. The scales are smooth, and there are several rows of weak ridges at the back center. Scale rows 19 ~ 17 ~ 15. There are 187 ~ 27 abdominal scales, single anal scale and 64 ~ 79 pairs of caudal scales. The back of the body is black, with about 7 narrow red stripes; The scales on the head are black with obvious red edges. There is a "ya" pattern on the back of the head. The abdomen is white, and gray-black spots are scattered in front of the anus. Sometimes the tail is all gray-black.
inhabit the fields; Areas near villages and water sources. Feeding on frogs, scorpions and fish. Violent, but non-toxic. Distributed in Zhejiang, Jiangsu, Anhui, Jiangxi, Fujian, Taiwan Province, Guangdong, Sichuan, Yunnan, Hunan, Hubei, Shandong, Shanxi, Hebei and other places.
after processing and catching, kill it, burn it, and grind it for use.
it is mainly used to treat chronic fistula and ulcer.
usage and dosage for external use: grind the powder and sprinkle it on the sore surface; Or insert the powder with medicine thread into the tube.
clinical application in the treatment of chronic tuberculous fistula
pharmacological effects
1. Anti-inflammatory effect, the water and alcohol extracts of red chain snake have obvious anti-inflammatory effects. 2g/kg, 1g/kg alcohol and water extracts can obviously inhibit the swelling of egg white and agar-induced rats' feet, which is similar to that of hydrocortisone 15mg/kg. At the same time, different doses of water and alcohol extracts can also obviously inhibit the otoinflammatory swelling of mice caused by xylene.
2. Analgesic effect, heat, electricity and chemical (antimony potassium tartrate) stimulation can prove that the water and alcohol extracts of red-chain snake have obvious analgesic effect, especially for chemical stimulation, and the effect on heat stimulation is the weakest.
3. Sedative and hypnotic effects. The 5% alcohol extract of this product has a strong hypnotic effect on the subthreshold hypnotic dose of pentobarbital sodium, inhibits spontaneous activity of mice, and prolongs the sleep time of pentobarbital sodium in mice; 1% alcohol extract has obvious direct hypnotic effect on mice, and its intensity is equivalent to that of 35mg/kg pentobarbital sodium, but the effect of water extract is not obvious.
4. Anti-shock effect. The alcohol extract of Agkistrodon acutus has antagonistic and protective effects on Resulin, Strychnine and Dianti Kenian Zhijue, especially the effect of 1% alcohol extract of 2g/kg. The strength is equivalent to that of 25mg/kg phenobarbital sodium, and the water extract has no effect.
kill the red chain snake, put it on the tile, burn it with pine wood and strong fire, grind it into fine powder and sieve it for later use. When in use, according to the size of the fistula, the red chain snake powder is twisted with paper and inserted; When the fistula is large, use paper twist or gauze to stick a little medicine into it; For the ulcer surface, the red chain snake powder can be thinly spread on the surface and wrapped with gauze. Change the dressing once every 2 days (the frequency can be increased or decreased as appropriate). More than 8 cases were cured, but 2 cases recurred. No adverse reactions were found during the treatment.
