The laboratory analysis conducted on a child with chronic nasal drainage reveals an elevated number of eosinophils on a white blood cell differential. Based on this finding, which is most likely the cause of the nasal drainage?
a. Bacterial infection
b. Viral infection
c. Chronic inflammation
d. Allergies
Answer: d. Allergies
Explanation:
During the allergy the eosinophils are recruited at the site and these are produced in large number by the bone marrow cells. The allergic conditions may developed during the sinus infections where chronic nasal drainage occurs in order to expel out the pathogen from the body. The parasitic diseases and allergic reactions will result in the excess production of the eosinophils.
The given situation is a result of the allergic reaction which brought about large increase in the number of eosinophils.

Answer:
Nowadays, liposomes have become very popular in carrying numerous molecules in cosmetic and pharmaceutical industries. In addition, in food and farming industries, it has been extensively studied that the use of liposome encapsulation to develop delivery systems. The new delivery system can entrap unstable compounds (such as antimicrobials, antioxidants, flavors and bioactive elements) and shield their functionality.
In recent years, liposomes are designed for advanced biotechnology product delivery systems, including antisense oligonucleotides, cloned genes, recombinant proteins and drugs. The delivery system using liposome has many benefits. For example, the solubility of lipophilic and amphiphilic drugs can be improved by loading them in liposomes.
Currently, because of severe side-effects and toxicity, quite a few drugs on the market can only be used in the direst situations. Many of these drugs have exceptional antimicrobial effect, however, the poor pharmacokinetic and pharmacodynamic properties limit their use. Drug encapsulation using liposomal or lipid drug delivery system can improve the problems mentioned above to such an extent. Therefore, the drugs can be brought into regular use with improved pharmacokinetic and pharmacodynamic properties.
