Clenbuterol "Clenbuterol" Residue
Clenbuterol is a white or off-white crystalline powder, odorless, bitter, melting point 174 ~ 175.5 ~ C, soluble in water, ethanol, slightly soluble in acetone, insoluble in ether; Its function of nutrient redistribution in the body. It is chemically stable and decomposes when heated to 172~C. It cannot be destroyed by general methods.
Clenbuterol can act on the p receptor of tracheal smooth muscle cells, causing smooth muscle relaxation and bronchiectasis, thereby achieving antiasthmatic effect. It can also act on the 6:receptor on the slow-shrinking fiber of skeletal muscle, which accelerates the contraction, which means that the hand can't hold, the walking is difficult, the skeletal muscle tremor of the face and neck, especially the sympathetic hyperactivity is more likely to occur. When activated, it inhibits the proliferation of lymphocytes, inhibits the formation of lymphokines and antibodies, and inhibits the induction of platelet activation. Clenbuterol can increase blood sugar, increase insulin secretion, cause anorexia; Clenbuterol can activate bones Na/K+/ATPase on the muscle cell membrane causes K+ to enter the cell, and the K+ concentration in the blood decreases, which induces arrhythmia. In addition, β2 receptor excitation can cause elevated blood lactate and pyruvate, and ketone bodies can occur, causing metabolic disorders. These pharmacological effects are responsible for the adverse reactions caused by clenbuterol hydrochloride.
Clenbuterol is easily absorbed after oral administration or after injection. Its bioavailability is higher than Other β-agonists, and its absorption rate in pigs can reach more than 0%. 10~20rain is effective after taking clenbuterol, and the concentration of 2-3L is high, the effect can be maintained for more than 5h, and the half-life is 25~29h. The absorption in livestock is similar to that of human beings. Most animals take oral After clenbuterol hydrochloride, the plasma concentration generally peaks within 2-3 hours. Oral administration of 14C-labeled clenbuterol to dogs, rabbits, rats and cattle. After 48 hours, the recovery of radioactive materials from urine was 71.9%, 74.7%, 74.7%, 41.5. % indicates that its absorption characteristics are different between species. After the pigs took clenbuterol hydrochloride, the clenbuterol hydrochloride could be detected in the urine in 1 hour, the concentration of 4-6b almost reached the peak, and with the increase of the internal dose, the clenbuterol in the urine was discharged. The concentration also increases accordingly, but the time to peak is the same. Cattle oral 5Ps / kg clenbuterol hydrochloride, the peak concentration of 2 ~ 9L after the first dose reached a peak, the continuous dose of blood for 21 days reached 1.lng / ml, this blood concentration of the double peak phenomenon, indicating the hydrochloric acid grams Lentrow has time accumulation in the process of absorption.
Whether oral, intravenous or spray, clenbuterol can be widely distributed in various tissues of the body, in the heart, liver, lung, kidney, spleen, gastrointestinal tract, bile, milk, fat, muscle, eyes, urine, It can be detected in stool, hair, etc. The organ distribution order of the 3H-labeled clenbuterol hydrochloride in the high to low organs was adrenal gland, kidney, lung, bone marrow, liver, heart muscle, and brain.
Clenbuterol hydrochloride is a moderately accumulating drug. The accumulation in animal tissues is related to its dose and duration of administration, and its residual amount gradually decreases with the extension of withdrawal period. A large number of tests have shown that the residues of clenbuterol in animals are mainly concentrated in the eyes, hair, lungs, liver, kidneys and muscle and adipose tissue. Among them, the remnant and choroid of the eye and the residual zui in the hair are high because it eliminates zui slowness; secondly, lung, liver and kidney; the residual condition in muscle tissue and fat tissue is roughly equivalent, about 1/5 of that in the liver. Clenbuterol is generally higher in the lungs and liver than in the kidneys and has a longer residual life.
Seed processing plant is a complete set production line composed of seed cleaning and treating procedures. Seed cleaning procedure will remove the dust, big size impurity, small size impurity, stones, immature, eaten, sicken seeds out. Seed treating procedure will coat the protective chemical film on seeds' surface to improve seed germination rate. One Seed Processing Line normally including following equipment: seed cleaner, Seed Grader , de-stoner, Gravity Separator , Seed Coating Machine. We will offer particular plant solutions for every different seeds processing requirements. Oversea installation and training is available.
We built over 10 sets seed processing plants at home abroad. Following are two cases reference.
10 ton/hour wheat Seed Processing Plant in Hebei, China.
This 10 ton wheat seed processing line includes: 5XTK-10 wheat huller, 5XZC-15 seed cleaner & grader, 5XZ-10 gravity separator, 5XFJ-10 seed Grading Machine , 2 sets 5BY-5B seed coating machine and 2 SETS DCS-50B Bagging Scale System.
Wheat seed processing line working flow:
Wheat huller: Hulling and removing the husk on wheat seeds
Seed cleaner & grader: Removing the dust, oversize and undersize impurity
Gravity separator: Separating the immature, eaten, sicken, moldy, bad seeds.
Grading machine: Grading wheat seed by size difference to 2 levels
Seed coating machine: The two different level seeds go to different seed coating machine for chemical dressing.
Bagging Scale : Finished wheat are being
weighted and packed to bag.
5 T/H rice seed processing plant in Ecuador
This client main crop is rice seed. Considering of the raw material condition, our engineer made following cleaning recommendation. Whole plant is made of drum precleaner, debearder, fine seed cleaner, thickness separator, gravity separator, seed coating machine, bagging scale system.
Whole plant functions introduction
