"Aspirin and penicillin are two of the most common drugs in use today. Clayman identified aspirin as an analgesic drug used for more than ... years to treat disorders such as headache, muscle ache, menstrual pain, joint pain and stiffness caused by osteoarthritis and to reduce fever. In terms of penicillin, Clayman says that this is the first group of antibiotic drugs to be discovered occurring naturally in the mold, penicillium, and made synthetically for use in..."

Abstract
This paper explains that, although aspirin has been found in many to be effective in treating patients with heart disease including myocardial infarction, many patients cannot successful take aspirin due to complicating factors that result in bleeding being triggered by aspirin. Next, the author presents an extensive literature review, the methodology for the original study and the results in table format. The paper concludes that this study found that aqueous solutions of acetylsalicylic acid (ASA) hydrolyzes rapidly, which correlates with a diminished 'ex vivo' ASA effect on platelet function. The paper includes 22 figures and three tables.

From the Paper
"The work of Hillman (2009) entitled: "Platelet Aspirin Resistance Detection and Validation" states that it was concluded by Tantry et al that the occurrence of aspirin resistance "in published reports is overestimated, implying that this was due to the use of assays that did not measure cyclooxygenase-1 (COX-1) activity. Although these investigators reported an incidence of aspirin resistance of _0.4%, several reviews estimate, based on a large number of studies, that the incidence of aspirin resistance is between 5% and 45%." There are stated to be serious limitations in the Tantry et al study that "call into question the generalizability of their findings." Stated first is that the research population of Tantry et al was comprised mainly of patients with stable angina. It is stated that a number of studies have demonstrated that "...aspirin resistance is more prevalent in patients with acute coronary syndromes than in patients with stable angina, and thus their study may underestimate the prevalence of aspirin resistance in those at greatest risk."
"Stated secondly is that through "...employing a dose of 325 mg of aspirin, their data may not be applicable to the vast majority of patients who currently are treated with 81 mg per day." Third stated is that because their definition of aspirin resistance "...has not been validated against clinical outcomes, it is arbitrary and thus must be viewed as speculative. Fourth, the thrombelastograph (TEG) assay they use has not undergone extensive critical evaluation.""

Abstract
This paper digs deeply into how aspirin and salbutamol were developed and also how they interact in the body from a heavy chemical and neurological perspective. It also gives a detailed overview into how, in general, pharmacueticals are developed using bronchodilars as an example. Also included are numerous diagrams in order to aid the reader comprehend the text.

"Since 400BC physicians prescribed a bitter powder extract from the willow bark tree to alleviate pain. In the middle of the 18th century two chemists by the name of Fontana and Brugnatelli extracted the active agent Salicin from the willow, and was then converted by Piria into Salicylic acid. Felix Hoffman a German chemist set about trying to synthesize salicylic acid."

"How Aspirin Works: New Understandings

Aspirin ranks as one of the world's oldest pain relievers. One form of the drug can be found in willow leaves. It has been sold in tablet form since about the turn of the century. Aspirin belongs to a group of about 24 similar pharmacologic agents known collectively as the nonsteroidal anti-inflammatory drugs. Despite the long history and widespread application of these drugs, however, the biological mechanisms responsible for their physiologic effects have remained largely unknown. Only in recent decades have researchers begun to understand how aspirin works at the molecular level.
In 1971, Vane and his associates discovered that aspirin inhibits prostaglandin formation. Prostaglandins are a type of fatty acid. Their formation represents the first committed step ..."

Abstract
The paper gives an overview of toxicological issues and their effects on health aspects. The paper explains why smokers have a greater risk for manifestation of asbestosis than do non-smokers, the scientific content breakdown of aspirin poisoning, the clear link between a low protein diet and increasing blood levels of cadmium and lead and, lastly, the dangers of alcohol. It explains how the human body is a very delicate piece of machinery with very fine balancing mechanisms and the effects that the toxicological issues mentioned have on it.

From the Paper
"Aspirin poisoning creates acid base abnormalities in the body and hence monitoring the blood and urinary Ph values are vital during the treatment. It is well known that blood is a well-buffered fluid system in the body and its normal Ph is 7.41. [DEHL] Since aspirin is quickly hydrolyzed into salicylic acid in the blood plasma there is an observed increase in acidity in the plasma. Increasing plasma salicylate levels leads to metabolic acidosis, which is compensated for by respiratory alkalosis resulting in fast deep breathing. The kidney, as an important homeostatic organ of the body, tries to compensate by absorbing h+ ions or HCo3 ions. An increase in urine ph in effect implies that there is an increase in acidity of blood, which the kidney tries to set right. Sometimes, alkaline diuresis maybe necessary to bring down the urinary and blood acidity levels and to facilitate the kidney in increasing the absorption and urinary elimination of salicylates. [eMedicine] Thus, in effect the blood and urinary Ph are vital statistics in the treatment of aspirin poisoning."

Abstract
The paper states that Tetrahymena are model organisms that are commonly used to study their feeding behavior over various environments and preys. They are common holotrichic ciliates easily grown in the laboratory, using pure liquid cultures. They acquire their nutrients by ingesting smaller microbes such as bacteria and fungi. The paper comments on the tests performed on Tetrahymena phagocytosis of Saccharomyces cerevisiae in the presence of different concentrations of aspirin. The paper records that after treatment, the cells were analyzed by flow cytometer via computer program, ColorCell software, when percent phagocytosis were identified. It was originally thought that aspirin would decrease the phagocytotic ability of Tetrahymena; however, the data concluded that aspirin does not alter this ability over a period of 4 minutes. The paper states that further analysis is necessary with longer treatment period and using various other drugs.

"Utilizing such power technology, we are now able to study the feeding behavior of our model organism, Tetrahymena sp., using FITC-labeled yeast and determine if the prey has been phagocytized. We will label Saccharomyces cerevisiae with FITC dye and detect the ingestion under different environments. So we would like to explore the following questions: How long does it take for Tetrahymena to ingest food? And, do different concentrations of aspirin affect Tetrahymena feeding behavior? "

"MORPHINE
Morphine is given for the relief of moderate to severe pain. It can be given in tablet form, or injection, or intravenous infusion, depending on the severity of pain and the duration of administration necessary. Morphine provides analgesia and sedation.
The precise method of analgesic action of morphine is unknown, but central nervous system opiate receptors have been found throughout the brain and spinal cord, and are likely to play a role in the analgesic effects of morphine. Once absorbed, morphine is distributed to skeletal muscle, kidney, liver intestinal tract, lungs, spleen, and brain. Virtually all of the dose is converted to glucuronide metabolites. Approximately 50 percent of the dose which will reach the.."

Abstract
This paper presents the case of EB, a 68-year-old Alaska native female who currently resides in an assisted living facility because she is no longer able to perform even basic functions of daily living. The author points out that her medications, which include reserpine and aspirin, are appropriate because of the long half-life of reserpine, efficacy at controlling EB's specific symptoms of declining mental capacity and underlying hypertension and the relatively low cost of the medications. The paper concludes that, although no cure exists for Alzheimer's, there are medications available now and under development to control the symptoms and perhaps slow the progression of the disease.

Conclusion

From the Paper
"Alternative pharmacological regimens to treat Alzheimer's include antioxidants, ergoloid mesylates and Huperzine A, along with others not mentioned. EB's presentation suggests that her disease progression and symptoms required medication to control her symptoms to prevent any further vascular accidents. In addition, there was little evidence to support alternative pharmacological regimens in her case. The expense, complicated dosing schedules, varying positive results, and possible negative side effects left too many gray areas to be considered a viable option for EB."

Abstract
This paper explains that nature acts as a pharmacy, offering us products, from the forest pharmacy and the pharmacy below water, with which we can heal ourselves: For example, aspirin, quinine, cyclosporins, and penicillin. This paper details the techniques that are available to researchers, to collect samples of natural products from the wild in a systematic manner, to extract compounds from these samples, to isolate the biologically-active compounds within these extracts, to characterize the biologically-active compounds chemically in terms of their structure, to evaluate the biologically-active compounds biologically, to determine potentially useful therapeutic effects and finally the methodology necessary to take these compounds to clinical trial. The author stresses the importance of finding new and more effective drugs to fight against bacterial infections and cancer. Outline.

Conclusion

From the Paper
"Chromatography is the process whereby two or more compounds or ions are separated through the distribution of the compound or ion between two phases, one that is mobile and the other which is stationary. These two phases can be of any combination: liquid-liquid, solid-solid, solid-liquid or gas-liquid, gas-gas, or gas-solid. There are many specific techniques for chromatography, some of which will be described below, and all follow the same basic principles. All forms of chromatography involve a rapid and dynamic equilibrium of molecules between the two phases, either free " mobile - or absorbed " stationary. Molecules will constantly move back and forth between the free and absorbed states, with millions of molecules absorbing and desorbing every second. The equilibrium between these states depends on three factors: the polarity and size of the molecule, the polarity of the stationary phase, and the polarity of the solvent. Thus, three different variables can be changed in chromatography, which can change the equilibrium between the stationary and mobile phases: this allows one to choose mobile and stationary phases that will separate just about any combination of compounds."
