I Was Pretty Lucky

There was a membrane between a rat's two stomachs, which made it impossible for rats to vomit.

But the vomiting response was a necessary part of animal testing. To ensure the thoroughness of the tests, a wide variety of animals were chosen, including mammals such as cats, dogs, and monkeys, which were quite sensitive to vomiting and suitable for testing this response.

Rhesus monkeys were widely used in animal experiments. Genetic sequencing studies had shown that humans and rhesus monkeys shared 93% of their DNA.

After the rhesus monkeys in the test group were given Active compound 2, they vomited.

Monkeys were intelligent animals, curious and mischievous.

Some of the rhesus monkeys in the test group sniffed their companions' vomit, making comical faces.

Compared with severe allergic reactions, liver and kidney failure, or even death, vomiting was a relatively mild drug side effect. The experimental animals had only experienced mild vomiting, so the corresponding test compound was still allowed to pass animal testing.

"Our Active compound 2 basically hasn't caused any serious side effects in animals. This compound is tentatively OK." He Lin and Cao Fan breathed a sigh of relief.

The animal testing for the LPJK1 project continued, and as time went by, the number of candidate compounds kept shrinking.

Half of the twenty-two active compounds were eliminated in a short time. The eleven remaining active compounds were still undergoing various tests on animals such as white mice, domestic dogs, and rhesus monkeys.

Next came eleven to ten, ten to nine, nine to eight... Shen Qi didn't need many of the compounds that made it through in the end. Usually, two or three would be enough, and there would never be more than five.

Once ten active compounds remained, the animal testing slowed noticeably.

The tests to narrow the
