adc1a438-b584-4d16-803a-8792b308af1e | An attack of migraine can be easily terminated by: | Acetylcholine | Ergotamine | Morphine | Ibuprofen | 1b
| single | SPECIFIC ANTIMIGRAINE DRUGS
Ergotamine: It is the most effective ergot alkaloid for migraine. Given early in attack, lower doses generally suffice, and relief is often dramatic. However, when pain has become severe-larger doses are needed and control may be achieved only after few hours. Oral/sublingual route is preferred. 1 mg is given at half hour intervals till relief is obtained or a total of 6 mg is given. Parenteral administration, though rapid in action is more hazardous.
Ergotamine acts by constricting the dilated cranial vessels and/or by specific constriction of carotid A-V shunt channels. Ergotamine and DHE have also been shown to reduce neurogenic inflammation and leakage of plasma in duramater that occurs due to retrograde stimulation of periascular afferent nerves. These actions appear to be mediated through partial agonism at 5-HTID/IB receptors in and around cranial vessels.

| multi | Answer is 'a' i.e. Epinephrine; 'b' i.e. ACTH ; 'c' i.e. Glucagon As already mentioned in one of the previous questions, the neuroendocrine response to injury is an impoant pa of the stress response. The release of various hormones, creates an altered metabolic state which helps the individual to survive through the injury or the adverse circumstances. The neuroendocrine response begins with activation of the hypothalamic-pituitary-adrenal axis hypothalmic activation leads to - ADH (or vasopressin) release from the neurohypophysis epinephrine secretion from the adrenal medulla norepinephrine release from sympathetic nerve endings - CRH travels to adenohypophysis, stimualting ACTH production. ACTH acts on adrenal coex, producing coisol release (ACTH also stimulates release of aldosterone from the adrenal coex) About other hormones Insulin - hormones and inflammatory mediators associated with stress response inhibit insulin release. This is required to achieve the hyperglycemic state after injury. Glucagon - increased Aldosterone - increased Thyroid hormones : Thyroxine-no change; T3 - decreased 3 - increased Sex hormones - decreased | Surgery | null |

— Robbins 9/e p864
Passive Congestion and Centrilobular Necrosis Hepatic manifestations of systemic circulatory compromise-passive congestion & centrilobular necrosis can be seen in both left & right-sided heart failure.
Pathology
Right-sided cardiac decompensation leads to passive congestion of the liver.
The liver is slightly enlarged, tense, and cyanotic, with rounded edges.
Microscopically there is congestion of centrilobular sinusoids.
With time, centrilobular hepatocytes become atrophic, resulting in markedly attenuated liver cell plates.
Left-sided cardiac failure or shock may lead to hepatic hypoperfusion & hypoxia, causing ischemic coagulative necrosis of hepatocytes in the central region of the lobule (centrilobular necrosis). Combination of hypoperfusion & retrograde congestion acts synergistically to cause centrilobular hemorrhagic necrosis.
The liver takes on a variegated mottled appearance, reflecting hemorrhage & necrosis in the centrilobular regions.

| multi | Ref:Textbook of pathology (Harsh mohan) 6th edition,page no.695 CLINICAL FEATURES. Renal cell carcinoma is generally a slow-growing tumour and the tumour may have been present for years before it is detected. The classical clinical evidence for diagnosis of renal cell carcinoma is the triad of gross haematuria, flank plain and palpable abdominal mass. The most common presenting abnormality is haematuria that occurs in about 60% of cases. By the time the tumour is detected, it has spread to distant sites haematogenous route to the lungs, brain and bone, and locally to the liver and perirenal lymph nodes. Systemic symptoms of fatiguability, weight loss, cachexia and intermittent fever unassociated with evidence of infection are found in many cases at presentation. A number of paraneoplastic syndromes due to ectopic hormone production by the renal cell carcinoma have been described. These include polycythaemia (by erythropoietin), hypercalcaemia (by parathyroid hormone and prostaglandins), hypeension (by renin), effects of feminisation or masculinisation (by gonadotropins) and Cushing's syndrome (by glucocoicoids). | Pathology | Respiratory system |

| single | Ans. B: Pressure Abrasion Teeth marks in biting and ligature marks in hanging and strangulation are example of imprint, pressure or contact abrasion Abrasion It as also known as - Graze or Scratch or Impression. An abrasion is a superficial injury to the skin which involves the loss of superficial epithelial layer (Uppermost layers of the cells of skin) of skin. Abrasions are produced by ? - Blow - Fall on some rough and hard substance - Dragging as in vehicular accidents. - Scratching with finger nails, bites and thorns etc. - Friction on some hard substance. Pressure of rope or cord as is found in strangulation and hanging etc. - Rubbing. - Indenting of the objects. Varieties of Abrasions Scratches- They are due to a sharp or a pointed object pressing across the skin, moving the surface layers in front of it and causing the heaping up of layers of skin. Grazes- They are modified scratches. - In this, the broader surface of skin comes in contact with the uneven rough object. - In this, the depth may vary at different places. - The direction is indicated by presence of clean commencement and tag at the finishing end. Impact Abrasions/Pressure Abrasions - They are also known as "Imprint abrasions". - They are caused by the stamping of some object against the skin like radiators of cars in vehicular accidents or - They may be caused by pressure on the skin which is accompanied by movements as found in? Ligature in cases of hanging or strangulation. Injuries caused by lashes with whip Sites of Abrasions ? The abrasions resulting from friction against rough surface during a fall are generally found on the bony pas and are accompanied with contusions or lacerations The abrasions caused by finger nails are seen on the exposed of body like - Face near forearm, hands, thighs etc. They are cresentric in shape, when finger nails are used. Ecchymosis is a common accompaniment. The abrasions caused by teeth bite are elliptical or circular in shape and often present separate marks. Typical impression of teeth by different sets of teeth (Deciduous or permanent) is marked. The intervening area is only a bruised area. The abrasions from radiators are honey-comb in appearance and are .commonly found in vehicular accidents Difference between Antemoem and Postmoem Bruise Antemoem abrasions will show signs of inflammation and repair whereas these will be absent in postmoem abrasions. | Forensic Medicine | null |

| multi | A nucleosome is a basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound in sequence around eight histone protein cores. This structure is often compared to thread wrapped around a spool. Nucleosomes form the fundamental repeating units of eukaryotic chromatin, which is used to pack the large eukaryotic genomes into the nucleus while still ensuring appropriate access to it (in mammalian cells approximately 2 m of linear DNA have to be packed into a nucleus of roughly 10 um diameter). Nucleosomes are folded through a series of successively higher order structures to eventually form a chromosome; this both compacts DNA and creates an added layer of regulatory control, which ensures correct gene expression. Nucleosomes are thought to carry epigenetically inherited information in the form of covalent modifications of their core histones. | Biochemistry | Metabolism of nucleic acids |

| multi | Ans. b (Binds to the same receptor binding-site as an agonist for that receptor but exerts the opposite pharmacological effect). (Ref. KDT, Pharmacology, 6th ed., p 41)# Receptor agonists, antagonists and inverse agonists bind to the same receptor types:DefinitionAgonistsincrease the inhibitory transmitter GABA potencyInverse agonistsdecrease GABA potencyAntagonistsblock action of agonists and antagonists# An inverse agonist is an agent which binds to the same receptor binding-site as an agonist for that receptor but exerts the opposite pharmacological effect. Inverse agonists are effective against certain types of receptors (e.g. certain histamine receptors/GABA receptors) which have intrinsic activity without the acting of a ligand upon them (also referred to as 'constitutive activity'.)# One particular example is R015-4513 which the inverse agonist of the benzodiazepine class of drugs.# Gabapentin acts by facilitation of GABA mediated CT channel opening. It does not block GABA receptors. Substances called Beta carboline which also bend this receptor cause stimulation anxiety, increased muscle tone and convulsions. They are inverse agonists of benzodiazepine receptors. | Pharmacology | General Pharmacology |
