How to convert the dose of traditional Chinese medicine compound decoction to rats?

Generally according to body surface area.

For conversion, you can refer to the total surface area conversion table of animals to calculate with a formula (some). According to the experience, the dosage per kilogram of body weight in rats is 6 times that of humans and 12 times that of mice.

The high, medium and low doses should be determined according to the dose-response curve of the pre-experiment, and after the conversion according to the animal coefficient, the approximate straight line from the onset to the lag effect is obtained by the pre-test, with the onset of effect being low, the stagnation effect being high, and the low and high opening of the root.

Finding the center, this is more accurate.

X-ray fluorescence can be used to analyze not only bulk samples, but also the composition and thickness of each layer of multi-layer coatings.

When the sample is irradiated by X-rays, high-energy particle beams, ultraviolet light, etc., due to the collision of high-energy particles or photons with the sample atoms, the inner electrons of the atom are expelled to form holes, so that the atoms are in an excited state, and the life of this excited state ions is very short, when the outer electrons jump to the inner holes, the excess energy is released in the form of X-rays, and new holes are generated in the outer layer and new X-ray emissions are generated, so that a series of characteristic X-rays are generated. Characteristic X-rays are intrinsic to various elements, and it is related to the atomic coefficients of the elements. Therefore, as long as the wavelength of the characteristic X-ray is measured, the element that produces that wavelength can be found.

You can do a qualitative analysis. Under the condition that the sample composition is uniform, the surface is smooth and flat, and there is no mutual excitation between the elements, when X-ray (a X-ray) is used as the original excitation sample to irradiate the sample, so that the elements in the sample produce characteristic X-rays (fluorescence X-rays), if the elements are the same as the experimental conditions, there is a good relationship between the intensity of fluorescence X-rays and the content of the analyzed elements. Quantitatively analysis can be performed depending on the intensity of the spectral lines.

According to the volume of the rat, as well as the instructions of the rat poison, according to the scientific ratio, to do the experiment, the amount of human and mouse medicine can not be converted.

This one. Ask your teacher!

If you don't care if the mice live or die, you can give it a try.

Advance warning, the mortality rate can be as high as 99% and above, and the mice are gavaged or so.

If you're lucky to be alive, the landlord can try...

Mice are administered by gavage;

rats were administered by gavage with 2ml of 100g;

Take the weight of the human as the standard, and increase or decrease it in proportion to the weight of the animal.

The main prescription is Buzhong Yiqi decoction, and the dosage of cohosh in the prescription is 3g.

It seems that there are: astragalus, bupleurum, angelica, cimicifuga, etc., because this is a traditional Chinese medicine, so there is a secret medicine, this secret medicine is not known to us, and it is not announced to the public. That's how I understand it.

I don't know the dosage, because I didn't ask if people didn't announce it. However, it feels good to use, and it has improved a lot.

Now that the industry is developing well, the outsourcing of biological experiment technology will also follow, for example, some universities or enterprises do not want to carry out some experiments internally, or the equipment involved is relatively expensive, and the technical requirements are high, and they will seek outsourcing. But now the competition is also relatively large, and it depends on how well the unit is doing as a whole. The better ones are generally in the Shanghai area, and you can take a look at Kilton Bio.
