Nanometer itraconazole external preparation and preparation method and use thereof

The invention provides a nanometer itraconazole external preparation and a preparation method and a use thereof, and the nanometer itraconazole external preparation comprises components of nanometer itraconazole and a matrix, wherein the matrix is selected from the multiple components of octodecyl alcohol, cetyl alcohol, stearic acid, isostearic acid, glyceryl monostearate, white vaseline, sodium lauryl sulfate, glycerin, liquid paraffin, solid paraffin, tween-80, tween-60, span-60, span-80, polyethylene glycol 4000, polyethylene glycol 400, polyethylene glycol 200, carbomer, propylene glycol, ethanol, benzyl alcohol, triethanolamine, carboxylation methyl cellulose, EDTA (ethylenediamine tetraacetic acid) or methyl hydroxybenzoate, and the content of the nanometer itraconazole is 0.1% by weight-10% by weight. By adopting the nanometer itraconazole external preparation, the shortcomings that the itraconazole is difficult to absorb in the external preparation, the skin penetration is not high and the percutaneous absorption rate of the itraconazole is not high are solved, the hepatotoxicity of the itraconazole during metabolism process of a human body is avoided, the bioavailability is improved, and a new administration way is provided for a patient.

Method for constructing soil of plough layer on coarse sand earth surface by heavy metal polluted sediment

ActiveCN103858552AImprove stabilityLeachable components are reducedSoil-working methodsSoil scienceSoil heavy metals
The invention discloses a method for constructing soil of a plough layer on a coarse sand earth surface by heavy metal polluted sediment. The method comprises the following steps of step 1), loosening the coarse sand surface to be regulated, and levelling the ground; step 2), laying the heavy metal polluted sediment on the coarse sand surface; step 3), sprinkling stabilizers on the heavy metal polluted sediment; step 4), performing rotary tillage for the first time; step 5), performing dry-wet alternating treatment for 15 days, and exposing to the sun for 7 days, and then performing rotary tillage for the second time, wherein the rotary tillage direction is opposite to that of the second time; after rotary tillage, the water mass fraction of a mixture of the sediment, the coarse sand and the stabilizers is naturally reduced to be 25-30%, performing alternating treatment and rotary tillage for the third time, wherein the rotary tillage direction is vertical to that of the second time; step 6), after performing rotary tillage for the third time, planting leguminous green manure for one crop, performing rotary tillage for the fourth time and returning the green manure to the field, and after two months, obtaining the soil of the plough layer. The heavy metal stabilization effect of the soil of the plough layer obtained by the method is obvious, and the heavy metal content of the planted vegetable crops conforms to the national standard.

Method for constructing plow layer soil on stony desertification ground surface by using heavy-metal polluted bottom mud

The invention discloses a method for constructing plow layer soil on a stony desertification ground surface by using heavy-metal polluted bottom mud. The method comprises the following steps: 1) crushing stones on the stony desertification ground surface to be regulated and flattening the ground; 2) uniformly laying river sand on the flatted ground; 3) laying the heavy-metal polluted bottom mud on the river sand; 4) spreading stabilizing agent on the heavy-metal polluted bottom mud; 5) performing rotary tillage for the first time; 6) performing dry and wet alternate treatment for 15 days, exposing under the blazing sun for 7 days and performing rotary tillage for the second time, wherein the rotary tillage direction is opposite to the rotary tillage direction at the first time; after the water content of the rotary tilled mixture of the bottom mud, the river sand and the stabilizing agent is naturally decreased to 25-30 percent, performing rotary tillage for the third time, wherein the rotary tillage direction is perpendicular to the rotary tillage direction at the second time; 7) after the rotary tillage for the third time, planting a crop of leguminous green manure, performing rotary tillage for a fourth time, returning the green manure into the field and obtaining the plow layer soil after 2 months. The plow layer soil obtained by adopting the method has a remarkable heavy-metal stabilizing effect and the heavy metal content of the planted vegetable crops meets the national standard.

Lime drying sludge stabilizer of heavy metal compound contaminated soil and application method thereof

The invention discloses a lime drying sludge stabilizer of heavy metal compound contaminated soil. The lime drying sludge stabilizer is prepared from the following components in parts by weight: 10 parts of lime drying sludge, and 2-3 parts of ferrous sulfate. The invention also provides an application method of the lime drying sludge stabilizer. The method concretely comprises the following steps: 1) paving the heavy metal compound contaminated soil on flat ground after crushing; 2) scattering the lime drying sludge stabilizer on the heavy metal compound contaminated soil; 3) carrying out rotary cultivation for the first time; 4) carrying out alternation of wetting and drying for 15 days, and carrying out rotary cultivation for the second time to obtain stabilized soil; 5) doping straw according to the volume ratio, and carrying out rotary cultivation for the third time, so as to obtain the tillable repaired soil. The invention also provides application of the lime drying sludge stabilizer of the heavy metal compound contaminated soil and the application method thereof in soil heavy metal pollution control. The invention also provides application of repaired soil obtained by using the application method of the lime drying sludge stabilizer in crop planting. The soil processed by the method is significant in heavy metal stabilization effect.
