Study Notes

Antiplatelet Drugs: Whereas the anticoagulant drugs such as Warfarin and Heparin suppress the synthesis or activity of the clotting factors and are used to control venous thromboembolic disorders, the antithrombotic drugs suppress platelet function and are used primarily for arterial thrombotic disease. Platelet plugs form the bulk of arterial thrombi. Acetylsalicylic acid (Aspirin) • Inhibits release of ADP by platelets and their aggreg…

Propofol -Intravenous Anesthetics - A nonbarbiturate anesthetic - It is very lipid-soluble, acts rapidly and has a short recovery time. - It is associated with less nausea and vomiting than some of the other IV anesthetics. - Propofol is very similar to thiopental in its effects on the cardiorespiratory system. - It does not have any analgesic properties but lowers the dose of opioid needed when the two agents are used in combination. - The most significan…

Electrochemical Corrosion Electrochemical corrosion is a significant phenomenon that can affect the longevity and integrity of dental materials, particularly in amalgam restorations. Understanding the mechanisms of corrosion, including the role of electromotive force (EMF) and the specific reactions that occur at the margins of restorations, is essential for dental clinics 1. Electrochemical Corrosion and Creep A. Definition Electrochemical Corrosio…

LARGE INTESTINE (COLON)  Congenital anomalies  1. Hirschsprung's disease produces a markedly distended colon, usually proximal to the rectum. Caused by a section of aganglionic colon, which failed to develop normally due to the absence of ganglion cells). This results in bowel obstruction and distention of the bowel proximal to the affected area. 2. Imperforate anus is due to a failure of perforation of the membrane that separates the en…

Factors , affecting glomerular filtration rate :  Factors that may influence the different pressure forces , or the filtration coefficient will affect the glomerular filtration rate .    1. Dehydration : Causes decrease hydrostatic pressure , and thus decreases GFR 2- Liver diseases that may decrease the plasma proteins and decrease the oncotic pressure , and thus increases glomerular filtration rate . 3- Sympathetic stimulation : will decrease…
