Why are there antibiotics and no preserving drugs?
Antibiotic was mainly used to fight diseases such as bacteria infection. Its mechanism of action was to suppress or kill the growth and reproduction of bacteria. Preservatives were mainly used to prevent products (such as cosmetics, food, etc.) from being contaminated by microorganisms. The two had different functions.
In drugs, if a antiseptic was added, it might bring some risks. For example, in people taking antibiotics, the antiseptic might affect the drug's properties and even cause a chemical reaction. Therefore, in order to ensure the effectiveness and safety of antibiotics, some antibiotics were not added with preserving agents.

Method for preserving jade ware
There were the following ways to preserve jade:
1. ** Storage environment **
- Jade articles were recommended to be stored separately because the texture of jade was relatively fragile. If it collided with other gemstones, it would easily cause cracks or damage, thus reducing its value.
- Jade collections should generally be placed in a relatively closed and humid environment to avoid being too dry or being exposed to the sun for a long time. In order to better preserve jade artifacts, especially ancient jade collections, it was best to store them in a constant temperature and humidity environment.
2. ** Daily maintenance **
- If it was jade, it could be soaked in water for 30 minutes before being washed and dried. Then, it could be placed in a sealed bag and stored in a cool and dry place. If it was Hetian jade, especially the seed material, it could be washed and dried with water (it was best to use pure water). Then, it could be dipped in a small amount of jade maintenance oil (water wax is also possible) with a clean fine brush and evenly applied to the jade. After that, it could be placed in a sealed bag, then placed in jewelry or packaging box and stored in a cool and dry place.
- For example, when a jade bracelet was not worn for a long time, a layer of light colorless oil could be applied on the surface of the jade. The oil should not be applied too much, just a little thinner. Then, the jade coated with oil should be packed in a sealed plastic bag to avoid being contaminated with dust.
- The best way to maintain it was to wear it or play with it. For Hetian jade, it could fully absorb the body's oil (note that it was not sweat or oil). When playing, it was necessary to keep the hands clean. Often playing with it could form a layer of oily pulp on the surface.
3. ** Points to note **
- To avoid collisions, especially on hard marble tables and floors.
- It was best to avoid wearing it when bathing to prevent the chemicals in the soap and shower gel from seeping into the jade surface and causing damage.
- When dirt or oil stains were attached to the jade surface, they should be washed with warm dishwashing liquid and then rinsed with clean water.
- Every half a year to a year, the bracelet or lanyard needed to be changed to prevent it from falling off and breaking.

Why is preserving life stories important?
Preserving life stories is important because it's like capturing a piece of history. It gives a voice to the voiceless. People's life stories are full of wisdom, lessons, and emotions. By preserving them, we are not only saving memories but also creating a tapestry of human existence. These stories can inspire others, provide a historical record, and contribute to the overall knowledge of humanity. For instance, the diaries of soldiers from a war can show the real - life situations during that time, which might be different from what is written in textbooks.

Method for preserving micro-biological samples
In hot and humid climate, when extracting contact biological evidence and other trace samples, the extraction and preservation of biological evidence on the spot is the key to quality control. The " Collection and Protection " reagent could be used to preserve biological samples. It had many advantages: it could easily transfer cells on the carrier, and the convenient preservation method could effectively prevent the deterioration, loss, and pollution of the physical evidence on the spot. Moreover, it could skip the process of collecting samples in the laboratory. After the acceptance was completed, DNA extraction could be carried out to improve the efficiency of laboratory work. The reagent was simple, convenient, and portable. It could be directly placed in the evidence collection box. The operation was simple, and the collection and preservation were completed in three steps. The original high-molecular active substances contained in it can effectively improve the efficiency of cell transfer from the carrier, increase the success rate of the collection tool, reduce DNA deterioration, and increase the positive rate of the test results; the DNA protectant can effectively protect the DNA from deterioration, eliminating the risk of material evidence DNA deterioration and loss of testing conditions during the period from material evidence investigation and extraction to laboratory testing.
Another biological evidence collection and preservation reagent, before being used for the collection and preservation of micro-biological evidence, must be sub-packaged, sealed, sterilized, and treated with no nuclear acid. Specifically, the reagent with the pH-value adjusted to 8.0 should be sub-packaged into a non-nuclear acid reagent bottle, sealed, and after high-pressure steam sterilization at a temperature of 121.3 ° C, pressure of 103.4kPa, and time of 20 minutes, 1ml of the reagent should be taken to extract DNA by the magnetic bead method, and then amplified by the reagent kit, and then used for the tandem repeat typing of the gel. If no DNA is detected, it is qualified.

A Complete Collection of Buddhist Life-preserving Fictions
" Cultivating Buddha " was a fantasy novel written by a lazy cat who was secretly reading books. The main character was a real monk, and the story was about cultivating Buddha.
