Dryness external

A suspension of 40 g 3-acetylaminomethyl-5-amino-2,4,6-triodobenzoic acid in 180 ml acetic anhydride were mixed with 0.4 ml concentrated sulfuric acid. An exothermic reaction was thereby initiated. Acetylation was completed by heating to 80°C for three hours. The reaction mixture was then evaporated to dryness in a vacuum at a temperature not exceeding 50°C. The residue was treated with a mixture of 30 ml concentrated aqueous ammonium hydroxide and 40 ml water, whereby the solid material dissolved with spontaneous heating. Within a few minutes, the ammonium salt of the acetylated product started precipitating. The precipitate and residual liquid were cooled externally with ice after about 15 minutes. The salt was separated from the liquid by filtration with suction, and was washed with ice cold saturated ammonium chloride solution. 

Iran. The grain is taken orally for intestinal inflammation and administered rectally for diarrhea. The grain flour is used externally to reduce topical inflammation, to remove rash and erythema, and to treat genital irritation in children resulting from contact with urine, and it is mixed with talc powder to prevent dryness of the skin . ... 

Dryness has a contracting and holding nature. It is associated with the Lung and predominates in the autumn. Pathogenic dryness can be divided into external dryness and internal dryness. 

External dryness is one of the six exogenous pathogenic factors it appears in the autumn and directly injures the Lung. In the early autumn, dryness is often combined with heat and it consumes the body fluid and Yin of the Lung - this syndrome is referred to as warm-dryness. In the late autumn, dryness is mainly combined with cold and causes obstruction of spreading of the body fluid of the Lung - this syndrome is referred to as cold-dryness. 

In clinical practice, external dryness and internal dryness can coexist. 

Sweet and cold herbs with a sticky and cloying nature should not be used in the syndrome of external dryness as they may hold onto the pathogenic factors. 

Shi Gao is sweet, pungent and cold, and enters the Lung meridian. It can intensively reduce the heat and protect the fluid of the Lung. It can be used in syndromes caused by both external and internal dryness. However, it is only used in these syndromes when the heat is strong and the Qi fails to descend. In these conditions, patients suffer from obvious shortness of breath, have a red tongue and a forceful and rapid pulse. 

EMOLLIENTS Soften, make supple, and counteract dryness and harshness of internal and external surfaces. —Liquorice, Marshmallow, Melilot, Slippery Elm. 

Isotretinoin, or 13-cw-retinoic acid, is widely used for the treatment of recalcitrant cystic acne. Although this drug more commonly affects the external tissues of the eye, causing ocular surface dryness, there is sufficient evidence to designate that this agent has a certain retinotoxic effect, causing nyctalopia. It also has a probably/likely designation for reversible decreases in color vision. 

Procedure. The chlorosulfonic acid in a beaker is cooled to —15°. The thiophene is added, with stirring (manual stirring rod) over a period of eight minutes, during which time the temperature rises to —5°. This mixture is immediately poured into 100 g. of crushed ice and the temperature of the quenched mixture is held below 30° by means of external cooling. The mixture is then neutralized with 325 ml. of 20% sodium hydroxide solution at a temperature below 40°. The aqueous solution is extracted three times with petroleum ether and then evaporated to dryness on a drum drier. The residue is extracted with boiling anhydrous methanol to remove the product from sodium sulfate and the alcoholic solution is dried on the drum drier (or the alcohol is evaporated and the product dried in a vacuum desiccator). The product is a white hygro-... 

Concentrating a large amount of a solution or a solid to dryness requires considerable time and is inefficient on a large scale. Commercial equipment is available for rotary evaporation of solutions in 100-liter flasks, but a half-filled 22-liter round-bottom flask is as much as most individuals can conveniently and safely handle without external support of the flask. On scale there is no immediate analogy to a rotary evaporator. Most concentrations are carried out in stirred vessels. 

The external Fire should not surpass the internal. The internal fire is a mercurial sap, a nectar of heaven, which makes the materia alive, maintains it and nourishes it until the end of the work. That is how the fleeting spiritual moistness (our moist fire or Azoth) dissolves the fixed, earthly dryness (the fixed natural sulphur). The latter is again impregnated with the fleeting moistness both intensify to a middle-substance (to a dry water), their sign is the blackness."... 

Wei Qiprotective energy generated by the Chinese Lungs. It is associated with the skin and protects the body from external pernicious influences (cold, heat, dampness, dryness, wind, summer heat).
