"The Whole River" is also a thing, although its details are rarely heard in ancient books, its nature can be slightly deduced from the name.
"The Whole River", it is said that it is related to the river, or born in the river, grows in the river, the river is vast, and the products are rich, and the things conceived must be extraordinary and vulgar. "The" Yuancheng ", the ancient giant turtle and the Chinese crocodile, are also behemoths in the water, powerful and long-lived, often mysterious." Shirat ", the wat was held by the ancient ministers of the dynasty, used to record events, and the" Shirat ", seems to be an act of presenting objects or gestures, or has a spiritual nature, and wants to convey something." "Wat rope", the rope is a rope, the sash is also a silk rope, that is, a ring. This number of objects may be carried by the river, or related to a specific thing.
This object may belong to the ancient god, hidden in the depths of the river, accidentally appeared in the world, with its strange shape and what it carried, showing a mysterious image. Its "show wat" action, either as a warning, or as a harbinger of auspiciousness. In the ancient ancestors, rivers were always places of awe. This whole river shows the wat and rope, or attracts people to look at it, awe, and think it is a sign of the river god. Its object may be a spiritual object between heaven and earth, obtaining the spiritual energy of rivers and rivers, and containing the mystery of nature. Although it is difficult to know the exact details, the name of it is enough to make people daydream about the mysterious connection between humans, nature and gods in ancient times.

The whole article is about the dangers of the peptide chain of the pufferfish toxin. I want to answer the ancient classical style of "Tiangong Kaiwu".
The peptide chain of the pufferfish toxin is extremely harmful. Bearing the brunt, it is related to life. The pufferfish toxin is highly toxic, and this peptide chain ring is its key component. If a person eats the pufferfish containing it by mistake, the poison will occur rapidly. At first, the lips and tongue are numb, and gradually the limbs are weak, and finally the breathing is paralyzed and the heartbeat stops suddenly. In a moment, life is in danger.
Furthermore, at the ecological level, there are also adverse effects. If the toxins in the pufferfish are over-enriched due to the peptide chain, or affect their own population reproduction. Moreover, river puffers occupy a specific position in the aquatic ecosystem, and their number of toxins changes abruptly, or the food chain is unbalanced. Downstream organisms may reproduce out of control due to the decrease in the number of river puffers, and upstream organisms may struggle to survive due to lack of food. The ecological balance is disrupted, which affects the whole body.
In addition, in the fishery economy, the scourge is very shallow. River puffers are subject to strict regulations on fishing, processing and sales due to the risk of toxins. If they accidentally enter the market, they will not only endanger the health of consumers, but also damage the reputation of the fishery, and the economic losses will be immeasurable. Practitioners need to be cautious and invest a lot of manpower and material resources to ensure that river puffers are non-toxic before they can be listed. The cost will increase greatly and the income will be limited, which will hinder the smooth development of fishery-related industries
Overall, the harm of the peptide chain of the pufferfish toxin is very important to personal safety, ecological balance and economic development. It must be treated with caution to prevent its harm from raging.

Quanze toad is a toad of the Salamander family, and the venom secreted by its venom glands can be processed to obtain toad crisp. This is a valuable Chinese medicinal material and exists in many pharmaceutical products.
In "Lei Gong Pao Pharmaceutical Solution": "Toad crisp, taste sweet, warm in nature, poisonous, enters the spleen meridian. The main carbuncle is swollen, sore, sore on the back of the hair, all evil swollen, breaking the crux, water dampness, detoxification, insecticide, and pain." It can be seen that its medicinal value is high. Many over-the-counter medicines are made of toad crisp as raw materials, such as Liushen Pills. This medicine is famous for its effects of clearing away heat and detoxifying, reducing swelling and relieving pain. It is often used to treat swelling and pain in the throat, carbuncle and sores, etc. Toad crisp is an important ingredient in this recipe. With its toxicity and pharmacological properties, it can detoxify and reduce swelling.
Also like Plum blossom point tongue pill, it also contains toad crisp. This medicine is used to treat the initial onset of carbuncle, swelling and pain in the throat and gums, etc. By virtue of the nature of toad crisp, it can promote blood circulation and remove blood stasis, reduce swelling and relieve pain, and make the evil of heat poison dissipate and swelling Another example is Sha medicine, which has a significant effect on relieving heat and avoiding filth, opening the orifice and detoxifying. In it, toad cake helps medicinal power to clear the orifice to wake up the mind, remove filth and detoxify, and deal with various diseases caused by the evil of filth and turbid feeling in summer and moon.
However, it should be noted that toad cake is toxic, and the medicine should strictly follow the processing specifications and dosage requirements. Proper processing can reduce its toxicity and improve the efficacy of the medicine. In clinical application, doctors must precisely control the dose to prevent the risk of poisoning. Therefore, although the products containing toad cake have unique curative effects, they must be used with caution and follow the doctor's advice.

Whole blood alanine aminotransferase (ALT) is an important indicator of liver cell damage. There are many detection methods, each with its own advantages and disadvantages, and is suitable for different scenarios. The following are common detection methods for you to describe in detail:
1. ** Reich method **: This is a classical colorimetric method, which is based on the principle of ALT catalyzing alanine and α-ketoglutaric acid to generate pyruvate and glutamic acid. Pyruvate reacts with 2,4-dinitrophenylhydrazine to generate phenylhydrazone pyruvate, which is reddish-brown under alkaline conditions. ALT activity is calculated by colorimetric determination of absorbance. The method requires simple instruments and is widely used in primary medical units. However, the Lai's method defines enzyme activity in Carmen's units, and lacks clear regulations on substrate concentration and reaction temperature, resulting in poor comparability of results in different laboratories. Moreover, the Lai's method has complicated operation steps, large manual operation errors, and limited sensitivity, making it difficult to meet the needs of accurate detection.
2. ** Rate method **: The rate method is based on the principle of enzymatic reaction kinetics. Under specific conditions, the rate of change of products or substrates during the reaction process is continuously monitored to determine enzyme activity. For ALT detection, the rate method indirectly determines ALT activity by monitoring the oxidation rate of NADH. Because of its simple operation, high degree of automation, and fast detection speed, it can process a large number of samples in a short time, and is suitable for batch detection in large hospitals and physical examination centers. The rate method also has good accuracy and reproducibility, and the results are highly comparable between different laboratories, providing a reliable basis for clinical diagnosis and treatment. However, the rate method requires high equipment and reagents, and the detection cost is relatively high.
3. ** Dry chemistry method **: The dry chemistry method is to fix the detection reagent on the dry sheet. After the sample is added dropwise, the color change or electrical signal change is produced by chemical reaction, and the result is read and analyzed by the instrument. In ALT detection, the dry chemistry method uses the reagent on the dry sheet to react with the sample, and the ALT activity is determined by reflectometry or differential potentiometry. The dry chemistry method is extremely simple to operate, does not require complicated sample pretreatment and reagent preparation, and is suitable for on-site rapid detection. The detection time is short, the results can be obtained immediately, and it has obvious advantages in emergency detection and other scenarios. However, the dry chemical method has high cost, harsh storage conditions and relatively poor stability.

If you want to reduce the use of casein and casein peptides in whole milk powder, you can follow the following methods.
First, choose the appropriate raw materials. When preparing whole milk powder, choose milk sources with low casein content. For example, milk produced by different breeds of cows may have different casein content. When selecting milk sources, screen carefully and take those with relatively small casein content, so as to reduce the amount of casein from the starting materials.
Second, optimize the processing technology. In the process of processing milk into milk powder, membrane separation technology can be used. This technology can separate different components in milk according to molecular size. With a membrane of a specific pore size, casein and casein peptide can be partially retained on one side of the membrane, while other ingredients can pass through, thereby reducing their content in the final milk powder product. Another example is to adjust the temperature and pH of the processing process. Casein has different solubility and stability under different temperatures and pH environments. After precise regulation of temperature and pH, casein can be moderately precipitated or denatured, which is easier to remove in subsequent separation steps and reduces its proportion in milk powder.
Third, add other ingredients to check and balance. Dietary fiber, prebiotics and other ingredients can be added to whole milk powder in an appropriate amount. Such ingredients may interact with casein and casein peptide in the intestine, affecting their absorption and utilization. Dietary fiber can adsorb some casein peptides, reducing the human body's intake of them. And these added ingredients may have other benefits to human health, which can optimize the nutritional structure of milk powder.
Fourth, develop new formulas. After in-depth scientific research and experiments, explore ingredients that can replace some functions of casein, and develop new milk powder formulas. This process requires fine experiments and demonstrations to ensure that the new formula milk powder can meet appropriate standards in terms of nutrition, taste and stability. It not only reduces the use of casein and casein peptides, but also ensures the quality and nutritional value of milk powder.
