Question
Lake Apopka, FL, early 1990s: after sunset, sometime in the spring. The eye-shine from the gators was visible from quite a distance. Thank goodness that Dr. Guillette had recruited a bunch of football players to work on his field research team! As the airboat quietly drifted towards the gators, one of the players would slowly reach down and then quickly snatch up a gator. A second player helped sit on the gator until Dr. G was able to tape the mouth shut. Then quickly a vial of blood was pulled from the sinus at the top of the head. The animal had a e marked, and length was measured. This one was a small one, only 133 cm. Time zero. One more was captured. Time 15 s enough for tonight. In stealth mode, the two gators were placed into the bed of Jack's pickup truck. Then off to the motel. Dr. G had gotten rooms at the very end of the motel, and as Jack backed into the space in front of the last room, Dr. G and Alex quickly moved the first gator into the bathtub. The second gator was put in the second room. Both had more blood drawn since it was time - 1 hour. Blood was drawn again at t 3, 5, and 7 hours. That last draw was always risky since the sun vas about to rise. Using extreme stealth mode, the three men took the gators back to Lake Apopka. One last blood draw at t-8 hours Exhausted, they headed back to Gainesville. Next weekend, they would do this again at another motel. They needed n-10 samples. But next week they were going to a different lake, a control site. That way they would alternate weeks of data from Lake Apopka and their control site. Pretty much, every weekend in the spring and summer this same stealth operation took place all over northern Florida Dr. Guillette's research was all about Endocrine Disrupting Chemicals. Lake Apopka was laden with DDE (the metabolite of DDT), and he had shown that this was very estrogenic. He now wanted to see whether DDE could also impact other steroids, and this was his experiment on cortisol and allostasis.Explanation / Answer
Cortisol is a steroid hormone produce by adrenal glands ,cortisol level increases if the body is undergoes prolong stress. This level affects the body if stay for long period of time.The physiological changes that would happen if cortisol level elevated abnormally includes :
