Study Notes

Agonist, Antagonist, and Partial Agonists Agonists:  molecules that activate receptors.  A drug that mimics the body's own regulatory processes. Antagonists:  produce their effects by preventing receptors activation by endogenous regulatory molecules and drugs.  Block activation of receptors by agonists. Noncompetive Antagonist:  Bind irreversibly to receptors, and reduce the maximal response that an agonist can elicit. Competitive…

Diseases from Str. pyogenes (Group A strep) 1.  Streptococcal pharyngitis.  Most frequent Group A infection.  Throat has gray-white exudate.  Infection may become systemic into blood, sinuses, jugular vein, meninges.  In less than a week the M-protein and capsule production decrease, and transmission declines. 2.  Skin infections, such as impetigo.  Especially in children.  Different M-proteins than in pharyngitis. …

Treatment by Location 1. Within Parotid Gland Close parotid capsule Apply pressure dressing 2. Over Masseter Primary anastomosis 3. Anterior to Masseter Primary anastomosis if possible If impossible: Drain proximal duct directly into mouth via new opening…

Management of Septic Shock Septic shock is a life-threatening condition characterized by severe infection leading to systemic inflammation, vasodilation, and impaired tissue perfusion. Effective management is crucial to improve outcomes and reduce mortality. The management of septic shock should be based on several key principles: Key Principles of Management Early and Effective Volume Replacement: Fluid Resuscitation: Initiate aggressive flui…

Applications/Use Load -bearing restorations for posterior  teeth  (class I, II) Pinned restorations Buildups or cores for cast restorations Retrograde canal filling material    (1) Alloy. An alloy is a solid mixture of two or more metals. It is possible to produce a material in which the desirable properties of each constituent are retained or even enhanced, while the less desirable properties are reduced or eliminated. (2)…
