This essay takes his work, Le Chavalier de la charrette, and applies the psychoanalytic techniques of Freud, thus discovering motivations for interactions among the characters in this romance. This is interesting for two reasons. Second, it shows that, although the societies of the twelfth and twentieth centuries appear to be very different on the surface, people still had the same sorts of problems in the past that we deal with on a regular basis today. The purpose of this experiment was to test a short-term heart preservation technique using a cardioplegic solution that acts as artificial blood. This solution was made by adding hemoglobin, the protein in human blood that allows erythrocytes to carry oxygen, to a Superperfusate solution.
Ischemia simulates conditions that occur in the heart during a heart attack.
Therefore if the experimental solution protects the rat heart better than the control solution, it may then be used on animal models that are more similar to humans in the hopes of finding a cardioplegic solution that prevents heart damage in humans. The experiment was conducted on experimental and control groups of eight WKY male rat hearts using the Langendorff heart perfusion technique. The data showed significant decreases in coronary flow and significant increases in diastolic pressures and creatine kinase, and no significant difference in systolic pressure in SP-Hb as compared to Krebs. The respiratory system involves a complex series of branching tubes leading from the nasal and oral cavities to the tracheobronchial tree and ultimately to the alveolar sacs where oxygen is absorbed and transported in the circulatory system. To prevent the debilitating effects of mucus pollutants or particles in the air, the respiratory system contains a Mucociliary Transport mechanism, which acts constantly to remove such debris.
