The experiment I predominantly worked on was with a rising junior at KAIST. He was working on a project to create an effective solution for weight control. The stage that I became involved was to determine which medicine caused the mice to lose or gain weight. For the first few days, I learned and practiced a specific procedure called oral gavage to feed the mice. When I became proficient with the procedure, I was assigned to feed 24 mice at the Specific Pathogen Free (SPF) lab every day. The SPF room is free of germs or pathogens, and to preserve the environment, I needed to be fully covered in the “dressing room,” wearing a mask, head and body wear, foot covers, and latex gloves. In addition to that, I had to be air showered for 15 seconds before touching any mice. Since going in and out of the lab can cause germs to enter, I had to bring all my materials all at once: 24 mice (8 cages), new cages, fresh food, syringes, microtubes, micropipette, testing solutions, a scale, and a beaker. When I enter the lab, the first thing I do is to replace the old cages with the new ones and to replenish their food in the cage. Then, I weighed each mouse to note the difference in their weight. Following that, I inserted the medicine (the function of medicine varies: some are to put on weight, some are to lose weight) proportional to the weight of the mouse. For example, if a mouse weighs 26.9 grams, then it needs to be injected with 269 ul. I repeated this procedure with all 24 mice, which takes about two hours.
