She also found the tiny red blood-blisters become larger and turn into purplish blotches on her skin. When asked about her diet, she told the physician she seldom had vegetables recently. The physician suspected that she has a disease called scurvy. Probably the physician suggest his patient have more A. vitamin A B. vitamin B C. vitamin C D. vitamin D E. vitamin E Histamine in loose connective tissue proper is released by A. fibroblasts B. macrophages C. eosinophils D. plasma cells E. mast cells A 25 year old patient came to hospital and complained that he married her wife several years ago but they could not have a baby. After careful medical examination, the physician found he got a disease called Kartagener’s Syndrome. Under electronic microscope, we will find which of the following structures in his trachea has problem? A. Goblet cells B. Small granule cells C. Basal cells D. Brush cells E. Ciliated cells After the ovulation, which of the followings remains in the ovary? A. Corona radiate B. Zona pellucida C. Liquor folliculi D. Secondary oocyte E. Theca folliculi Which one of the following structures is crucial for urine concentration? a) Renal corpuscle b) Filtration membrane (blood-urine filtration barrier) c) Proximal convoluted tubule d) Henle’s loop e) Distal convoluted tubule A 6-year old girl went to hospital with his father. Her father told the physician that he found her daughter sometimes had difficulties to breathe, especially in the night after she had a fever, and this usually makes her daughter feel uncomfortable and can not fell asleep. The physician checked her lung and found nothing abnormal but much more mucus in her trachea, but the anemoscope test result suggests her bronchioles in lung are narrow than usual. The physician realized that she has sensitized mast cells, which own the Fc receptors of antibodies on the cell membrane. When the Fc receptors bind the same antibodies at the second time, the sensitized mast cells in her bronchioles will release histamine, resulting in asthma. The same procedures also happen in anaphylactic shock and hay fever. Which of the following immunoglobulins involve in her syndrome? A. IgA B. IgD C. IgE D. IgG E. IgM In dendrites of neuron, we can find the following structures under electronic microscopes, EXCEPT the A. smooth endoplasmic reticulum B. ribosome C. Golgi complex D. neurofibril E.
