The cardinal side effects such as excessive potassium excretion and sodium retention, enhanced gastric acidity, oedema, psychosis and negative nitogen balance are some of the exaggerated manifestations of the normal metabolite functions of cortisol. Most importantly, the determination of cortisol levels is considered useful in the diagnosis and treatment of various ailments, namely : Addison’s Disease i. In the actual radioimmunoassay the cortisol present in the extract competes with Cortisol-H3 (i. Now, the free cortisol is quantitatively removed by adsorption on dextran-coated charcoal from the one bound to the transcortin. Finally, the bound radioactivity (due to Cortisol-H3) is measured which is then employed to calculate exactly the amount of cortisol present in the sample by the help of a Standard Curve (or Calibration Curve). Procedure : The various steps to be followed sequentially for the assay of cortisol in plasma are as follows : (1) The cortisol is usually extracted from the samples drawn from the patients, as follows : Place 100µl of plasma in each of two tubes and add 2. Set tubes 1 and 2 aside until Step-13, Step-6 From this point onwards the various tubes are treated as follows : Step-7 Incubate tubes 3 through 18 and all patient sample tubes in a pre-set constant temperature water-bath at 45°C for exactly 5 minutes, Step-8 Immediately after Step-7 incubate tubes 3 through 18 and all patient tubes in an ice-water bath (0 to 4°C) for 30 minutes. Shake the rack several times at short-intervals to ensure that the tubes attain 0-4°C rapidly, Step-9 Quickly add 0. Shake each vial to solubilize the contents: An emulsion should form, and Step-15 Count the radioactivity in the vials in sequence for 1 to 10 minutes. Now, subtract the blank from all other counts per minute to obtain the actual counts per minute and average the counts per minute for vials 1 to 2 to find the total count per minute. The percent bound may be calculated using the following expression : Counts per minute % Bound = × 100 Total counts per minute Finally, plot the percent bound Vs nanograms (ng) per tube of cortisol standard either on linear or on semilog paper and make use of this Standard Curve to calculate the amount of cortisol present in the unkown samples. The basic principles underlying both automated and unautomated methods of analysis are more or less the same. Out of the broad-spectrum of biological samples blood analysis is the most common one. There exists a number of parameters which may be assayed, and spectrophotometry is ideally suited for nearly all of them, a few typical examples are cited in Table 2. Glucose Glucose reduces Cu2+ to Cu+ ; & Cu+ reduces 420 phosphomolybdic acid (Folin-Wu) 4. To the resulting solution phosphomolybdic acid is added, which is subsequently reduced by Cu2O to give rise to an intensely coloured ‘molybdenum blue’ that is measured at 420 nm accurately. The major component parts com- prise of the various important sections namely : the preparation section, the reaction section and the analysis section which will be discussed briefly here. Preparation section Reaction section Analysis section Flame photo Dialyzer meter Recorder Proportioning heat Sampler or pumps bath Colori computer phaser meter Programmer Figure 2. Preparation Section This particular section of the Auto Analyzer consists mainly of the sampler, proportioning pumps, and programmer. First, the sampler introduces a fixed quantity of serum sample into the ‘analysis train’, which varies from one instrument to another instrument supplied by different manufacturers. The proportioning pump controls the rate of advancement,viz 10 inch/minute, of each sample through the analysis stream. Each analysis stream is made of transparent plastic flexible tubing, and each patient-sample is separated from one another by an air- bubble. Reaction Section The reaction section essentially comprises of the dialyzer, heat bath and phaser, and obviously the reaction takes place in this zone. Evidently, B is added always in excess to ensure : (a) rapid reaction, and (b) complete reaction by forcing the reaction to the right in accordance to the Le Chatelier’s principle. Therefore, in actual experimental operations temperature is increased by the aid of a heat-bath so as to accelerate the reaction which in turn allows the reaction to attain equilibrium state as rapidly as possible. Naturally at a very high temperature there is every possibility for decomposition of either the products or the reactants. Analysis Section The recent advancement in the field ofcomputer technology and anlytical instrumentation it has become very easy and convenient to have the analyical data from a series of biological samples processed at high speed as digital readouts or on computerized recorders. Many hospitals round the globe make extensive use of advanced computer softwares for data processing as stated beiow : • Uptodate listing of various laboratory tests, • Listing of drugs and metabolites that cause interference both biochemically and analytically, • Storing of levels of biologically important compounds for various disease states, and • A tentative diagnosis for a patient based on his serum sample under investiation together with the drugs and dosages being administered and the levels of biologically important compounds. Caution : Nevertheless, the concerned physician or pharmacist must exercise his or her own expertise and knowledge while prescribing drug(s) to a patient along with these computerized data informations.

However order altace 10 mg without a prescription, psychosis order 2.5 mg altace amex, mental deficiency, or amnesia would more than likely lead an interrogator or examiner to the conclusion that the person is not a reliable source of information who can be expected to report events accurately and realistically. Thus, the primary aim of this behavior is evasion rather than the financial gain which is often the motivation for simulating physical disease. More specifically, it is an evasion of responsibility, the responsibility for past acts or for future acts, as related to the giving of information. In this chapter, then, malingering refers to the planned and deliberate simulation of mental symptoms for the purpose of evading responsibility. The bulk of it is impressionistic and subjective, and at times there is more disagreement than agreement among the writers. Much of the polemics revolve around issues such as the moral reprehensibility of malingering; whether or not the malingerer is, by definition, an emotionally disturbed person; the differentiation of malingering from the Ganser syndrome; whether or not the Ganser syndrome is an hysterical or psychotic reaction; and the difficulties of detecting malingering. For the most part, it appears that those who are optimistic about detecting malingering might do well to share some of the pessimism of their colleagues. As Davidson (19) points out, even the best clinicians make errors in this area, and MacDonald (58) stresses the need for professional skill and long experience in determining whether malingering is an element of the clinical picture. Hopefully, this may present certain reference points for thinking about malingering and evaluating it, and may provide an orientation for organizing techniques to detect malingering. Studies from the experimental literature which deal with related concepts will be included. The following four pathological states will be considered, the simulation of which might lead the interrogator to conclude that the source is unreliable or incompetent: psychosis, the Ganser syndrome, mental deficiency, and amnesia. Adoption of a Deceptive Role The simulation of psychosis or of any mental aberration may be considered as a conscious and deliberate attempt to take a specific social role. According to Sarbin (77), the concept of role deals with the organized actions of a person in harmony with a given status or position. A position may be considered a system of rights and duties exercised by the person who occupies the position. The role expectations, which are learned through direct or indirect experiences, deal with with the behavior expected of the occupant of a particular position, and with the behavior anticipated of the person occupying the reciprocal position in the social interaction situation. Thus the position or status of the mentally ill person is culturally transmitted just as any other role, and consists of a system of expectations about the behavior of the mentally ill person. It also includes the reciprocal expectation that the person dealing with the deranged patient will protect him, consider him not responsible for his actions, prevent him from doing harm, make few if any demands on him to be rational, and institute therapeutic and rehabilitative measures. The organized behavior of the individual, directed toward fulfilling these expectations of the self and other, is called the role. Thus, the person who plays the role of the psychotic is trying to determine the role of the examiner or interrogator, and he expects a certain response from him. How successful he will be in enacting that role seems to be dependent on three factors. The second appears to be related to a generalized skill at taking and -279- enacting roles. Finally, certain enduring or temporary motivational and qualitative characteristics of the self structure are probably influential in determining the choice and adequacy of the role. This possible consonance of basic personality to enacted role is one of the most complicating factors in recognizing malingering, and is one with which almost all workers in this field have wrestled. Although these notions on role behavior may help in understanding malingering in general, there is as yet little empirical work which would aid in the prediction of the persons and the circumstances which might combine to produce simulation of psychosis. It is apparent that almost all individuals play different roles, and the role played is partly dependent upon who the partner is in the social situation. Block (9) and Block and Bennett (11) have demonstrated that a single subject varies his behavior as the interpersonal situation changes. The complexity of this understanding did not appear to be a function of self and ideal-self discrepancy in a homogeneous sample of college students. However, Gough (35) and Cameron (14) have argued that role-taking ability is related to emotional well-being. Studies by Sarbin and Farberow (78), Sarbin and Hardyck (79), and Sarbin and Jones (80) have tended to confirm that adequate role perception and validity of role enactment are positively related to adjustment.
