문제1
Small, dense LDL is most likely to interact with arterial walls, leading to deposition of cholesterol, and initiating or worsening atherosclerosis. Small, dense LDL is associated with more than a three-fold increase in the risk of coronary heart disease.
Large, buoyant LDL is less atherogenic than small, dense LDL.
The LDL phenotype A is normal. It is the so called 'B' pattern that is associated with increased risk.
Which of the following is most likely to interact with arterial walls, leading to deposition of cholesterol, and initiating or worsening atherosclerosis?

Hives and rash usually indicate an allergic reaction. Hematuria is due to a variety of causes. Fever and chills usually indicate a febrile reaction. Positive DAT due to conditions other than sensitization to red cell alloantigens is not uncommon. Therefore a positive DAT in the posttransfusion specimen with a negative DAT in the pretransfusion specimen is more likely to indicate alloimmunization.
The most definite indication that a patient has been sensitized to a specific red cell antigen is:

High triglycerides may be caused by disorders such as type 2 diabetes, hypothyroidism, Cushing's sydnrome, liver disease, uremia, dysglobulinemia, nephrotic syndrome, and alcoholism can cause hypertriglyceridemia.
A 46-year old known alcoholic with liver damage is brought in the ER unconscious. One would expect his lipid values to be affected in what way?

문제6
P. vivax characteristically displays Schuffner's dots and often enlarged RBCs along with brownish granules. P.
vivax can also have 12-24 merozoies in each cell, actually filling the entire RBC. This parasite also has very irreglar shapes often referred to as "Ameboid".
P. falciparum and P. malariae do not display Shuffner's dots, therefore could not be the correct choice.
P. ovale does display Shuffner's dots in all stages, but characteristically has about 8-12 merozoites in rosettes or irregular clusters inside the RBC. Also, P. ovale characteristically shows enlarged, ovoid RBCs with fimbriated edges.
Identify the parasite of a patient with suspected malaria who demonstrates the following findings on a blood smear:
- Enlarged RBCs, some with fine brownish granules
- > 15 parasites in some cells
- Ameboid structures
- Schuffner's dots

문제7
Electrophoresis uses an electric field to separate molecules based on differences in net electrical charge. The rate of electrophoretic migration is also dependent on the ionic radius of the molecule, the viscosity of the solution through which it is migrating, the electrical field strength, temperature, and the type of supporting medium used.
Electrophoretic separation fundamentally relies on:

문제8
Overcentrifugation may cause either a false negative result (if too much agitation is required for resuspension), or a false positive, (if centrifuged clumps cannot be completely dispersed). High concentration of IgG paraprotein, and failure to adequately wash cells can leave unbound IgG which will neutralize antiglobulin reagent. Delay of addition of antiglobulin reagent may allow previously bound IgG antibody to dissociate from red cells.

문제9
Insulin is the hormone that is mainly responsible for the entry of glucose into the cell for energy production Glucagon and epinephrine promote glycogenolysis, conversion of glycogen to glucose, which increases plasma glucose. Cortisol, along with glucagon, increases gluconeogenesis, formation of glucose from noncarbohydrates, which also raises plasma glucose concentration.
