An anesthetic (or anaesthetic) is a drug to prevent pain during surgery, completely blocking any feeling as opposed to an analgesic. A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesia, although others are used commonly by all disciplines. Anesthetics are categorized into two classes: general anesthetics, which cause a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body while maintaining consciousness. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. We produce anesthetic raw materials like tetrcacain, lidocaine prilocaine. These three anesthesia products are in commercial quantity.

Water tank storage method of cucumber
Late autumn cucumbers or plastic greenhouses can be stored in autumn to extend the supply period. For storage of cucumbers, the maturity of harvesting may be slightly more tender than that of the commonly-listed commercial melons, but it must not be too tender. Excessive melon strips are susceptible to dehydration or rot during storage. It is best to store fresh cucumbers with cucumbers, and avoid cylinders with oily or pickled vegetables and other odors. When using the old cylinder, clean it with boiling water and alkaline surface a few days before storage, put it in a cool place in summer, place it in a warm place in winter, keep the clean water in the cylinder 10 to 20 centimeters deep, put a piece of wood at 5 centimeters from the water surface. Well-shaped frame, put on the rack with a rake. A circular basket made of bamboo or bamboo baskets is placed on the rice dumplings and placed on a cucumber. The use of large cylinder storage, the melon strip can be placed flat, the cylinder center to form a space, in order to facilitate ventilation, code to the cylinder mouth 10-12 cm so far. If the cylinder is small, the head of the melon is down, and the stalks are upright. After the code is finished one level, put a derrick frame above it, so as not to press the cucurbit handle of the first layer, and then lay the second layer, and determine the number of layers according to the length of the melon strip and the height of the cylinder. Ask for a code. Immediately after entering the tank, cucumbers are sealed with kraft paper or plastic film. The cylinder should be placed in a cool room. Take measures to keep warm after the weather turns cold; avoid below 10°C. Cylinder method makes the cucumber in a semi-closed state, easy to maintain a high temperature and humidity, in addition, the cylinder oxygen content decreased, carbon dioxide content increased, changed the atmosphere of the storage environment, received the effect of modified atmosphere storage. Generally can be stored for 30 to 40 days.
