"It's really swimming!"

"It's incredible!"

When the frozen fish frozen by liquid nitrogen was put into room temperature water, it was "resurrected", attracting the children present for a while.

On the afternoon of August 13th, the first cord blood science science research journey and the awards of the "umbilical blood science science painter" were held in Guangdong Province (hereinafter referred to as the "Guangdong umbilical blood bank") in Guangdong Province. The 22 cord blood storage households participated in the event. The youngest child is 4 years old and the largest child is 12 years old. The event goes back to the "umbilical traces" of life through the interesting scientific experiments and popular science lectures. veil.

Frozen fish resurrection experiment to understand the "umbilical traces" of life

At the beginning of the activity, the simulation cell freezing experiment "Frozen Fish Resurrection Experiment" made the children who came to study opened their eyes. I saw a lively catfish carefully put in -196 ℃ liquid nitrogen by the experiments, and the fish was immediately frozen. Subsequently, the experiments put the frozen fish in room temperature water, and the fish "resurrected" and jumped again.

The staff explained that liquid nitrogen is a substance with colorless, tasteless, and extremely low temperature. Due to its chemical inertia, it can directly contact biological tissues and will not destroy biological activity. Therefore Cells, even live tissue. The umbilical blood is stored in the liquid nitrogen tank of -196 ° C. However, the actual freezing process of the umbilical umbilical blood is much more complicated. It needs to go through the rigorous computer program to achieve the frozen temperature step by step. In the end middle.

Subsequently, the children started a magical journey of umbilical blood science science. By visiting the science popularization hall, laboratory, watching popular science cartoons, popular science lectures, and popular science knowledge and answers, they truly approached unique, cutting -edge life science and technology, and felt The magical charm of umbilical blood, cultivate scientific sentiments, and improve the quality of science and culture.

"Umbilical Heart Cooperation Qiqi Painting Qi Popular

It is worth noting that the award ceremony of the "Umbilical Blood Science Popular Popular Popular Practical Practical Practical Popular Popular Popularization" was also held on the day of the event. On Children's Day this year, the umbilical blood storage of Guangdong Province launched the "childlike heart, 'umbilical' painting the future" umbilical treasure painting contest, inviting children to paint the image of anime mascot "umbilical treasure". The competition received the enthusiastic support of the children, and a total of 69,466 votes were collected by the children's total votes. After strict selection and screening, 20 outstanding works were finally selected, and the author was awarded the honorary title of "Umbilical Blood Science Popular Popular Popular Popular Practical".

At the end of the activity, the families participating in the research activities jointly completed a big painting theme of umbilical blood science. The work will be displayed in the umbilical blood bank in Guangdong Province. To the citizens who come to visit, they will popularize the valuable medical value of umbilical blood and call on more families to protect the umbilical blood resources together.
