  • What is ‘biochemical pharmacology’? • A fancy way of saying ‘pharmacology’, and of hiding the fact that we are sneaking a subject of medical interest into the UW biochemistry curriculum. • An indication that we are not going to discuss prescriptions for your grandmother’s aching knee; we will focus on the scientific side of things but not on whether to take the small blue pill before or after the meal. What is it not? • A claim that we accurately understand the mechanism of action of each practically useful drug in biochemical terms.

  • Drug Administration be very precise. (Standardized medicinal teaspoons and tablespoons are available.) Eye drops and nose drops (A) are designed for application to the mucosal surfaces of the eye (conjunctival sac) and nasal cavity, respectively. In order to prolong contact time, nasal drops are formulated as solutions of increased viscosity. Solid dosage forms include tablets, coated tablets, and capsules (B). Tablets have a disk-like shape, produced by mechanical compression of active substance, filler (e.g., lactose, calcium sulfate), binder, and auxiliary material (excipients).

  • Hypertension and coronary heart disease (CHD) are of great importance. Hypertension affects above 20% of the total population of the USA with its major impact on those over age 50. CHD is the cause of death in 30% of males and 22% of females in England and Wales. Management requires attention to detail, both clinical and pharmacological. The way drugs act in these diseases is outlined and the drugs are described according to class.

  • Chronic consumption For benefits of chronic alcohol consumption, see page 187. Central nervous system. The development of dependence on alcohol appears to involve alterations in central nervous system neurotransmission. The acute effect of alcohol is to block NMDA receptors for which the normal agonist is glutamate, the main excitatory transmitter in the brain. Chronic exposure increases the number of NMDA receptors and also 'L type' calcium channels, while the action of the (inhibitory) GABA neurotransmitter is reduced.

  • The putative CLL precursor could be an antigen-experienced CD27+ B cell, expanded either in the course of a GC B-cell T-dependent or T-independent response by chronic antigen- stimulation through extrinsic or autoantigens. Over time, genetic abnormalities may accumulate in the genome of these chronically stimulated B cells and lead to the outgrow of clones with MBL phenotype. Additional genetic aberrations may be incorporated in the course of proliferation leading to the oncogenic hit that transform these precursor in bona fide CLL cells. ...

  • Calculate the Nernst equilibrium potential for sodium, potassium, and calcium ions given their intracellular and extracellular concentrations. 3. Describe how changing the concentrations of sodium, potassium, and calcium ions inside and outside the cell affect the resting membrane potential in cardiac cells. 4. Explain why the resting potential is near the equilibrium potential for potassium and the peak of an action potential approaches the equilibrium potential for sodium. 5.

  • The calcium ion plays a critical role in normal cellular function and signaling, regulating diverse physiologic processes such as neuromuscular signaling, cardiac contractility, hormone secretion, and blood coagulation. Thus, extracellular calcium concentrations are maintained within an exquisitely narrow range through a series of feedback mechanisms that involve parathyroid hormone (PTH) and the active vitamin D metabolite 1,25-dihydroxyvitmin D [1,25(OH)2D]. These feedback mechanisms are orchestrated by integrating signals between the parathyroid glands, kidney, intestine, and bone (Fig.

  • Cytosolic phospholipase A2 -a (cPLA2 -a) is a calcium-activated enzyme involved in agonist-induced arachidonic acid release. In endothelial cells, free arachidonic acid is predominantly converted into prostacyclin, a potent vaso-dilator and inhibitor of platelet activation. As the rate-lim-iting step in prostacyclin production is the generation of free arachidonic acid by cPLA2-a, this enzyme has become an attractive pharmacological target and the focus of many studies.

  • Many of my friends have been anxious ever since Osteopathy became an established fact, that I should write a treatise on the science. But I was never convinced that the time was ripe for such a production, nor am I even now convinced that this is not a little premature. Osteopathy is only in its infancy, it is a great unknown sea just discovered, and as yet we are only acquainted with its shore-tide. When I saw others who had not more than skimmed the surface of the science, taking up the pen to write books on Osteopathy, and after having carefully examined their productions,...
