Summary Introduction
To review:
The method to avoid the placebo effect in a new drug test.
Introduction:
A placebo is a false treatment that looks like the real treatment, but is not. A placebo does not contain the active substrate that is supposed to help the treatment, it can be a sugar pill that looks exactly like a real capsule or an injection containing just water. During the clinical study, researchers give placebos to a specific group known as a placebo group to compare the effectiveness of the new drug that is given to another group known as the treatment group. It allows researchers to understand what would happen if the drug is not given.

Recently, athletes have begun to take advantage of the benefits of extra red blood cells, in a process known as `` blood doping`` (You can do your own research on it). Two weeks prior to a competition, a blood sample is taken and centrifuged, and the red blood cell component is stored. A few days before the event, the red blood cells are injected into the athlete. Why would athletes remove red blood cells only to return them to their bodies later? What problems could be created.
Homeostasis is a natural phenomenon which is body’s tendency to maintain
internal stable and favorable environment against any situation that would tend to disturb its normal condition and function. Such as, If the temperature rises, the body loses heat by sweating or panting, via the latent heat of evaporation. If it falls, this is counteracted by increased metabolic action, by shivering and in fur or feather coated animals, by thickening the coat. Like temperature our body can sense the change in osmolarity and to maintain a stable condition body needs to persist on a certain osmolarity. Secretion of certain hormones
can be stimulated by any change in the osmolarity to help maintain a certain level of osmolarity - briefly discuss the mechanism of action and biochemical function of such a hormone.
