People with Rhinovirus infections of the nose and throat have an 80-fold increase in kinins and no increase in histamine. What do you expect for rhinoviral symptoms? What disease is caused by rhinoviruses?
I bet this answer is in your textbook. Is it really that hard? There's this thing called google...
Based on the information provided, we know that people with Rhinovirus infections experience an 80-fold increase in kinins but no increase in histamine.
Kinins are a type of protein that can cause blood vessels to dilate and increase their permeability, leading to redness and swelling. Therefore, with the increase in kinins, we can expect symptoms such as nasal congestion, nasal discharge (runny nose), and throat irritation. These symptoms are often associated with the common cold, which is caused by Rhinoviruses.
Histamine, on the other hand, is a chemical that is typically released in response to allergic reactions. Since there is no increase in histamine, we wouldn't necessarily expect symptoms such as itching, sneezing, or watery eyes, which are commonly associated with allergies and not typically seen in rhinoviral infections.
To get this information, we rely on scientific studies and research that investigate the effects of Rhinoviruses on the body. These studies involve collecting samples from infected individuals, analyzing the levels of various chemicals and proteins, and observing the resulting symptoms. By comparing the findings to the symptoms experienced by the patients, researchers can establish the connection between the increase in kinins and the specific symptoms associated with rhinoviral infections.
