They may reach man an essential part of housing not only because it provides through water and vegetables.

Soil bacteria Types of Soil dispose of all the organic waste matter dumped on the soil, if the required warmth, oxygen and moisture are The superficial layer of soil is called supersoil and is made available. They break up complex nitrogenous matter, of decaying animal and vegetable matter (humus) such as proteins, into ammonia, H2S and simple mixed with sand, dust and stone particles. The soil nitrogenous compounds and finally convert them by below the surface is called subsoil which may be: oxidation into end products such as nitrites, nitrates, • Rocky or stony, made up of chalk, limestone, sand- carbonates, chlorides and sulphates.

The control of heat-dissipating responses is an example of a proportional control system antibiotics for uti starting with m best 100mg cyclidox. Each response has a core temperature threshold-a temperature at which the response starts to increase-and this threshold depends on mean skin temperature virus scan for mac cyclidox 100 mg with mastercard. At any given skin temperature virus yang menyerang hewan buy cyclidox american express, the change in each response is proportional to the change in core temperature, and increasing the skin temperature lowers the threshold level of core temperature and increases the response at any given core temperature. In humans, a change of 1°C in core temperature elicits about nine times as great a thermoregulatory response as a 1°C change in mean skin temperature. These graphs show the relations of back (scapular) sweat rate (left) and forearm blood flow (right) to core temperature and mean skin temperatures ( ). Cold stress elicits increases in metabolic heat production through shivering and nonshivering thermogenesis. However, there is an overall 4 to 8 cycles/min “waxing-and-waning” activity that is clinically apparent during intense shivering. Although these efferent impulses are not rhythmic, their overall effect is to increase muscle tone, thereby increasing metabolic rate. Once the tone exceeds a critical level, the contraction of one group of muscle fibers stretches the muscle spindles in other fiber groups in series with it, eliciting contractions from those groups of fibers via the stretch reflex, and so on; thus, the rhythmic oscillations that characterize frank shivering begin. Shivering occurs in bursts, and signals from the cerebral cortex inhibit the “shivering pathway,” so that voluntary muscular activity and attention can suppress shivering. Because the limbs are part of the shell in the cold, trunk and neck muscles are preferentially recruited for shivering-the centralization of shivering-to help retain the heat produced during shivering within the body core; and the familiar experience of teeth chattering is one of the earliest signs of shivering. As with heat-dissipating responses, the control of shivering depends on both core and skin temperatures, but the details of its control are not precisely understood. Temperature receptors in the body core and skin transmit information about their temperatures through afferent nerves to the brainstem and, especially, the hypothalamus, where much of the integration of temperature information occurs. The sensitivity of the thermoregulatory system to core temperature enables it to adjust heat production and heat loss to resist disturbances in core temperature. Sensitivity to mean skin temperature lets the system respond appropriately to mild heat or cold exposure with little change in body core temperature, so that changes in body heat as a result of changes in environmental temperature take place almost entirely in the peripheral tissues (see Fig. For example, the skin temperature of someone who enters a hot environment may rise and elicit sweating even if there is no change in core temperature. On the other hand, an increase in heat production within the body, as during exercise, elicits the appropriate heat-dissipating responses through a rise in core temperature. Most of these are warm sensitive, meaning they increase their activity with increased brain temperature. In experimental mammals, temperature changes of only a few tenths of 1°C in the hypothalamus elicit changes in the thermoregulatory effector responses. However, the cold sensitivity of most of them seems to be due to inhibitory synaptic input from the nearby warm-sensitive neurons. They are located in the esophagus, stomach, large intra- abdominal veins, and other organs. Consider what happens when some disturbance-say, an increase in metabolic heat production resulting from exercise-upsets the thermal balance. The central thermoregulatory controller receives information about these changes from the thermal receptors and elicits appropriate heat-dissipating responses.

Other important points The characteristic features seen in the kidney are called benign nephrosclerosis include: • Hyaline arterioslcerosis • Normal or small kidney size with leather grain appearanceQ. Hyperplastic arteriosclerosisQ: Proliferation of the internal smooth muscle cells seen in the interlobular arteries giving onion skin like appearanceQ Renal involvement is called malignant nephrosclerosis having the features like a. Kidneys have a typical “fea bitten “appearanceQ (due to petechial hemorrhage on cortical surface) b. Necrotizing glomerulonephritis: Necrotizing arteriolitis may involve the glomeruli also. But after discussion with many senior faculty members, the answer of consensus is option ‘a’ i. Electron microscopy reveals increase in number of myoflaments comprising myofbrils, mitochondrial changes and multiple intercalated disks. Fatty streaks begin as multiple yellow spots approximately 1 mm in diameter which join to form streaks approximately 1 cm long. They may contain a few lymphocytes, but foam cells are the predominant constituents. The fatty streaks are not signifcantly raised, so, they do not disturb normal blood fow. They can be seen in the aortas of children less than 1 year old and are present in the aortas of all children over 10. Whereas some fatty streaks maybe precursors of atheromatous plaques not all fatty streaks progress to these more advanced atherosclerotic plaques. Moreover, they frequently affect individuals in locations and populations with a low lifetime incidence of fully devel- oped atheromatous plaques. Small, pinpoint petechial hemorrhages may appear on the cortical surface from rupture of arterioles or glomerular capillaries, giving the kidney a peculiar “fea-bitten” appearance. Though these are nonspecifc, they can be seen with Marfan diseaseQ and scurvyQ 74. Aortic dissection occurs principally in two groups: • Men aged 40 to 60, with antecedent hypertension (more than 90% of cases of dissection); • Younger patients with systemic or localized abnormalities of connective tissue affecting the aorta (e. They are the second most common vessel (after abdominal aorta) to be affected in atherosclerosis. An aneurysm is a localized abnormal dilation of a blood vessel or the heart); it can be congenital or acquired. When an aneurysm involves an intact attenuated arterial wall or thinned ventricular wall of the heart, it is called a true aneurysm. Moreover, infections with these or- ganisms are exceedingly common (as is atherosclerosis), so that distinguishing coincidence from causality is diffcult. Ans (c) Hyaline arteriosclerosis (Ref: Robbins 9/e p490, 8/e p495) The following are the two patterns of vascular changes in hypertension Hyaline Arteriolosclerosis Hyperplastic Arteriolosclerosis • Vascular lesion consists of a homogeneous, pink, hyaline • Vascular lesion has onionskin, concentric, laminated thickening of the walls of arterioles with loss of underlying thickening of the walls of arterioles with progressive narrowing structural detail, and with narrowing of the lumen of the lumina • Seen in the elderly, hypertensive and diabetic • Seen in but not exclusively in malignant hypertension, • Hyaline arteriolosclerosis is more generalized and more • Frequently accompanied by deposits of fbrinoid and acute severe in patients with hypertension. Kawasaki’s disease affects children but the presentation is fever, cervical lymphadenopathy, skin rash, oral ulcers, con- junctivitis and edema of hands and feet. However, Robbins confuses the issue by mentioning that Hypersensitivity vasculitis is the other name of microscopic angiitis. Direct quote from Harrison 18th/2798 ‘Post capillary venules are the most commonly involved vessels; capillaries and arterioles may be involved less frequently’.
