In this essay I will be contrasting and comparing ancient Egypt and Greek medicine. In fact there are many differences from Greek medicine to Egyptian. For instance the Greeks believed in the 4 humours. The Theory of the Four Humours was an important development in medical knowledge. The Greeks believed that the body was made up of four main components or Four Humours.
Biochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining.
Antibiotics are produced by microorganism because they inhibit the growth of or kill other microorganisms; they are effective in low concentrations and act on specific species of microorganisms. 3. List four different ways that the antibiotics work to destroy or inhibit microorganisms and for each give named example of an antibiotic exhibiting this type of mechanism. (Note: you need to indicate the different processes or structures affected not simply variations or subsets of a process) Inhibit cell-wall formation: blocks a specific cross linking step in the bacteria in the process of reproduction. E.g.
The Western scientific approach to medicine bases on these main features, focusing on the abnormalities in the body, biological factors explain the illness, it examines the cause of ill health through observations and tests, trained health professionals are the ones able to identify and treat the illness, emphasising different treatments medications and other interventions. Health care environments are appropriate places to undergo treatments and the model specifically states that illness is regarded as a temporary condition which can be reversed by the intervention of medical expertise. The bio medical model relates to the functionalist approach of health as it specifies that health is the absences of disease and it’s regarded as dysfunctional for the society as individuals cannot make positive contribution to the running of society. The model does not consider the social and environmental factors of ill health but relays on the scientifically methods to address and diagnose the illness if the illness cannot be diagnosed the individual would be labelled as malingering meaning one will be pretending to be ill for
Diagn Interv Radiol 2011; 17:135–142 © Turkish Society of Radiology 2011 ABDOMINAL IMAGING P I C T O R I A L E SSA Y Congenital and acquired abnormalities of the portal venous system: multidetector CT appearances Nilgün Işıksalan Özbülbül ABSTRACT A knowledge of normal anatomy as well as the most frequent variants and abnormalities of the portal venous system are of great importance for liver surgery and interventional procedures. An understanding of the varied MDCT appearances of these abnormalities will allow more definitive diagnoses and help avoid false diagnoses. Key words: • portal vein, abnormalities • portal vein, thrombosis • portal vein, gas • shunts, arterioportal • tomography, X-ray computed he portal venous system is associated with a wide range of congenital abnormalities and acquired processes that can be detected incidentally with current imaging modalities. In this pictorial essay, we discuss and illustrate the normal anatomy as well as the congenital and acquired abnormalities of the portal venous system as shown by multidetector computed tomography (MDCT). Recognizing the varied features of these abnormalities of the portal venous system will help radiologists to correctly interpret images and prevent misdiagnoses.
Naturopathic Philosophy Case Analysis Essay Word Count: 1070 The time spent in consultation with a patient is one of the biggest differences between naturopathy and conventional medicine. In order to establish a detailed understanding of the patient’s current health a thorough medical history as well as a look at their diet and lifestyle habits needs to be taken. There are six fundamental healing principles that underpin the practice of naturopathy. Three of those principles are Vis Medicatrix Naturae – The Healing Power of Nature, Primum Non Nocere – First Do No Harm and Tolle Totem – Treat the Whole Person. Each of these principles directly relates to the need for a naturopath to collect in-depth information from patients in the initial consultation.
in nature, the bacteria can transfer these plasmids from bacteria to bacteria, transfering those beneficial genes. this mechanism allows bacteria to adapt to new and foreign environments. the continuous resistance of bacteria to antibiotics is due to the transmission of these plasmids. Bio-Rads unique pGLO plasmid encodes the gene for GFP and a gene for resistance the antibiotic ampicillin. pGLO can also control the gene expression of this fluorecent protein.
2. What morphological structure is responsible for bacterial motility? Flagella 3. Why is a wet preparation discarded in disinfectant solution or biohazard container? Because of the Preparation of micro- organisms which can interact with the people or environment surrounding them.

(1983) prepared morphogenesis-inducing extracts from various isolated bacteria of M. oxyspermum belonging to the genera Cytophaga, Flavobacterium, Caulobacter, and Pseudomonas. Matsuo et al. (2003, 2005) identified Cytophaga sp. (YM2-23) of the Cytophaga–Flavobacterium–Bacteroides complex, which excretes the morphogenesis-inducing substance thallusin and restores the foliaceous morphology of M. oxyspermum. The authors reported that the same factor also partially promotes the formation of distromatic thalli of U. pertusa and other Ulva species, highlighting the potentially important role of thallusin for the normal development of green macroalgae.
