Study Notes
Hepatitis D Virus
- Hepatitis D virus (Delta agent) is a defective virus that can only replicate in cells already infected with Hepatitis B virus.
Anticoagulants
- All anticoagulants act by removing calcium except Heparin.
Intracellular Fluid
- The major action of intracellular fluid is related to potassium (K).
Uric Acid
- Uric acid is the end product of purine metabolism.
- It is not the major form of nitrogen excretion in man, nor is it important for the synthesis of adenine, a major component of bile, or the end point of cholesterol metabolism.
Cholesterol Esters
- Most of the cholesterol esters found in the blood are fatty acids.
Extracellular An-Ion
- The major extracellular an-ion is Chloride (Cl).
Serum Proteins
- The protein found in the highest concentration in serum is Albumin.
ASO Titer
- An elevation of the ASO titer over 200 IU in a patient's serum may indicate Acute Streptococcus pyogenes infection.
Childhood Diseases
- The causative agent of a disease with symptoms of coryza, conjunctivitis, low-grade fever, and Koplik's spots is Measles virus.
Prions
- Prions are best described as Infectious proteins with no associated nucleic acid.
Influenza Virion
- The nucleic acid of an influenza virion consists of Eight segmented single-stranded RNA genome with Negative polarity.
Interferon
- The mechanism of antiviral activity of Interferon is to Inhibit translation of Viral mRNAs.
