The general approaches employed to reduce systemic absorption of an ingested poison where the client still has an intact gag reflex is to administer an emetic (eg cardura 2mg fast delivery wide pulse pressure icd 9. Within clinical environment generic 4 mg cardura with amex hypertension arterielle, more invasive procedures such as gastric lavage and haemodialysis can be performed order cardura master card blood pressure emergency room. Antidotes are available against poisoning with the following substances and are able to reverse the toxic manifestations (see table 11. Describe poisoning management measures that hinder the absorption of the poison from the gut. A prescription is a written order by a registered physician, dentist or veterinarian to prepare and/or dispense pharmacological agents for patient. A drug that requires a prescription from a licenced prescriber to be dispended by a pharmacist is termed legend drug. In precompounded prescription, drugs prescribed are supplied by the pharmaceutical companies in ready prepared form by its nonproprietary or trade name. Constructin of a prescription: A ideal prescription should contain a) the name, qualification, registration number, full address, telephone number and working hours of the physician; b) the full name, sex, age and address of the patient; c) the diagnosis, the drug preparation, total amount, frequency of administration advises and signature of the prescriber. The name of the drug preparation begins with the symbol Rx means take thou derived from a Roman symbol for Jupiter. Prescription incompatibility: In competency or careless of the prescriber results incompatable prescription. It may lead to failure of desired therapeutic goal, may prove harmful or even death to the patient. Patient’s compliance: A matter of concern for prescriber with regard to prescription is patient’s noncompliance i. Noncompliance includes taking of inadequate doses, improper timing, preterm discontinuation of drug. Criteria for rational prescribing: Rationa prescribing should meet the certain criteria such as appropriate diagnosis, indication, drug, patient, dosage, duration, route of administration, information and monitoring. Irrational prescription: Over use of antibiotics, indiscriminate use of injections, excessive use of drugs, use of anabolic steroids for growth and use of tonics and multivitamins for malnutrition are some of irrational practices.

Diagnostic ultrasound imaging depends on the computerized analysis of refected ultrasound waves, which non-invasively build up fne images of internal body structures. The resolution attainable is higher with shorter wavelengths, with the wavelength being inversely proportional to the frequency. However, the use of high frequencies is limited by their greater attenuation (loss of signal strength) in tissue and thus shorter depth of penetration. Generation of ultrasound Piezoelectric crystals or materials are able to convert mechanical pressure (which causes alterations in their thickness) into electrical voltage on their surface (the piezoelectric efect). Conversely, voltage applied to the opposite sides of a piezoelectric material causes an alteration in its thickness (the indirect or reciprocal piezoelectric efect). If the applied electric voltage is alternating, it induces oscillations which are transmitted as ultrasound waves into the surrounding medium. The piezoelectric crystal, therefore, serves as a transducer, which converts electrical energy into mechanical energy and vice versa. Ultrasound transducers are usually made of thin discs of an artifcial ceramic material such as lead zirconate titanate.

The growing emergence of resistance phenomenon led to new classes of antibiotics of synthetic origin purchase 2mg cardura with mastercard heart attack zippo lighter. Unfortunately discount cardura 2 mg otc heart attack or gas, the rate of new and more efficient antibiotics is not as fast as microorganisms finding new ways to survive order cardura 4 mg with amex arteria rectalis media. Thus, in the beginning of the 21st century we assist to a race to plants, trying to discover innovative natural weapons to fight infectious diseases and microbial contaminations in food. Since medicinal plants produce a variety of substances with antimicrobial properties, it is expected that screening programs discover candidate compounds for the development of new antibiotics. However, scientific research to determine the therapeutic potential of plants is limited, there is a lack of scientific studies that confirm the possible experimental antibiotic properties of a large number of these plants. It is expected that compounds that reach targets different from those used by known antibiotics may be active against resistant pathogens. All of these are, generally, widely available in nearly every corner of the world. Apart from the world areas associated with great vegetable diversity, like tropical regions, densely forested areas of South America, sub-Saharian Africa or Southeast Asia, we also can find a great number of plants/herbs with medicinal use. In an academic study made in 2002, in a Portuguese National Park, with a relatively small area, 346 hectare, 140 different plants were found, with 124 different medicinal uses, 15 aromatic, 16 categorized also as condiments and 20 others, including 2 specimens classified as toxic/poisonous (Rodrigues, 2002). Table 1 lists a number of well-known plants and herbs, many used daily worldwide, and their most important antimicrobial component. Common name Scientific denomination Antimicrobial component Alfalfa Medicago sativa Allspice Pimenta dioica Eugenol Aloe Aloe barbadensis / Aloe vera Latex Apple Malus sylvestris Phlosetin (flavonoid) Basil Ocimum basilicum Terpenoids Bay Laurus nobilis Terpenoids Black pepper Piper nigrum Piperine Caraway Carum carvi Coumarin Cashew Anacardium purshiana Polyphenols Chamomile Matricaria chamomilla Phenolic acid Chili peppers Capsicum annuum Capsaicin Clove Syzygium aromaticum Eugenol Coriander Coriadrum sativum Dill Anethum graveolens Terpenoids Eucalyptus Eucalyptus globulus Tannin Fava bean Vicia faba Fabatin Garlic Allium sativum Allicin Olive Olea europaea Hexanal Onion Allium cepa Allicin Peppermint Mentha piperita Menthol (terpenoid) Rosemary Rosmarinus officinalis Terpenoids Thyme Thymus vulgaris Caffeic acid, thymol, tannins Turmeric Curcuma longa Curcumin (terpenoid) Table 1. Plants and herbs and their main antimicrobial components (adapted from Cowan, 1999). Within the Gram positive group, lactic bacteria are considered the less sensitive (Zaika et al. Confirming the greater susceptibility to herbs and condiments of Gram positive bacteria when compared with Gram negative, an experiment using forty-six methanolic extracts of dietary spices and medicinal herbs reached results in which Staphylococcus aureus was the most sensitive bacteria and Escherichia coli the less sensitive bacteria to the extracts tested. The other test species included Bacillus cereus, Listeria monocytogenes and Salmonella anatum. The experiment also has shown a strong positive correlation between antibacterial activity and the total phenolic content of the herbs (Shan et al. Garlic and clove are widely used for culinary purposes due to their strong flavour and aroma. They are also some of the most widely refered condiments in scientific literature when comes to antibacterial activity. Some bacteria that show resistance to conventional antibiotics are susceptible to decoctions or extracts of garlic and clove. Garlic, in particular, was able to inhibit Staphylococcus epidermidis and Salmonella typhi after one and three hours, respectively. In terms of yeast inhibition, it took one hour to achieve it, and in terms of inhibition diameter, reached larger areas of inhibition for Candida than those produced by nystatin. Clove took five hours to completely inhibit yeasts, including Candida species (Arora & Kaur, 1999). There are indications that some spices, or their components may be active not only against resistant strains, but also against clinical isolates (usually studies are carried on academic collection strains).
