Changes in collagenases and TGF-beta precede structural alterations in a model of chronic renal fibrosis. (1/56)
BACKGROUND: To study the role of collagenases and transforming growth factor-beta (TGF-beta) in the genesis of interstitial fibrosis, we used the model of bromoethylamine (BEA)-induced papillary necrosis, which is known to lead over a period of 1 to 12 months to interstitial fibrosis and renal insufficiency. METHODS: Rats were injected with BEA, and urine and kidney tissue (cortex and medulla) were collected after 1, 2, 3, 7, and 30 days. One kidney was perfused and fixed for morphological studies and immunostained for collagen type I, III, and IV. The other kidney was used to prepare cortex and medulla extracts for gelatinases (by fluorometric and zymographic techniques), tissue inhibitors of metalloproteinase-1 (TIMP-1), and TIMP-2 (by enzyme-linked immunosorbent assay, ELISA) and TGF-beta1 (by ELISA). RESULTS: Albuminuria and interstitial fibrosis were present in BEA rats by day 7, which continued until day 30. Immunocytochemical staining for collagen types showed that collagen III and IV increased in the interstitium by day 30, but collagen I remained unchanged. Gelatinase activity in the medulla decreased by 57% compared with control by day 2 and remained low until day 30. In the cortex, gelatinase activity remained unchanged between 0 and 7 days after BEA but decreased by 72% by day 30. TIMP-1 and TIMP-2 were decreased by 80% compared with day 0 in both the medulla (by day 1) and cortex (by day 2) and remained low up to day 30. TGF-beta1 immunoreactivity increased progressively until day 2 in the medulla (16-fold higher than control) and day 3 in the cortex (8-fold higher than control) and returned to control level by day 3 in the medulla and by day 30 in the cortex. Two days after BEA injection, the mRNA for TGF-beta1 was increased eightfold in the cortex and 12-fold in the medulla, and it remained high for up to 30 days. CONCLUSIONS: The fibrosis that follows papillary necrosis is associated with both high TGF-beta1 expression and depressed gelatinolytic activity. (+info)Deafness and liver disease in a 57-year-old man: a medical history of Beethoven. (2/56)
Ludwig van Beethoven had a number of medical conditions, including deafness and chronic liver disease, for which there are contemporary descriptions. An autopsy was performed on the day after his death. Physicians and historians have tried to reinterpret original sources to determine the causes of his deafness and systemic illnesses. We have reviewed the differential diagnoses that have been proposed by otologists and physicians. Clinical and post-mortem findings point to renal papillary necrosis and liver cirrhosis of unknown aetiology. In the absence of further histological examination, there is no definitive answer to the cause of his deafness and gastro-intestinal symptoms. (+info)Experimental hypertension. The effects of chemical ablation of the renal papilla on the blood pressure of rats with and without silver-clip hypertension. (3/56)
Because of the ease with which ablation of the renal papilla of the rat can be effected by chemical means, a study was carried out to determine the effects of this ablation on the blood pressure. Significant elevation was found, lennding support to the idea of the antihypertensive role of the renal medulla. Constriction of one renal artery of rats with their papillae removed resulted in a more rapid and greater elevation of pressure than the same procedure in rats ith their papillae intact. The rise in pressure approximated the sum of the rises caused by removal of the papilla alone and by renal artery constriction alone, consistent with the idea of two mechanisms being at work in this model. (+info)The induction of renal papillary necrosis in Gunn rats by analgesics and analgesic mixtures. (4/56)
Homozygous members of the mutant Gunn strain of Wistar rats genetically lack the enzyme uridine diphosphate glucuronyl transferase. "High" and "low" dose gavage feeding for 18-34 days of an analgesic mixture containing aspirin, phenacetin and caffeine (APC) confirmed the previously reported susceptibility of these animals to analgesic induced renal papillary necrosis. Heterozygotes do not share the gross enzyme deficiency of homozygotes and, when treated with APC under identical conditions, failed to develop renal papillary necrosis. Groups of homozygotes were dosed by gavage with aspirin, phenacetin and paracetamol for 4 weeks. Renal papillary necrosis was produced by all 3 drugs, the lowest frequency of lesions occurring with phenacetin. It is postulated that the enzyme deficiency of homozygous Gunn rats influences the metabolism of analgesics to favour the excretion of nephrotoxic metabolites. The renal papillary necrosis appearing in these experiments is essentially an acute lesion, differing both in natural history and morphology from the renal papillary necrosis of analgesic nephropathy, suggesting that the pathogeneses of the experimental and human lesions differ. (+info)Renal papillary necrosis. (5/56)
Renal papillary necrosis (RPN) is a significant problem in human beings, especially in England and in Australia where it has been reported to account for 15% to 20% of patients needing renal transplants. Many compounds, including aspirin, phenacetin, phenylbutazone, indomethacin, mefenamic acid, flufenamic acid, fenoprofin, naproxen, and ibuprofen have been linked to renal papillary necrosis in human beings. Although the exact mechanism of RPN is unknown, there are several theories that have good scientific evidence behind them. Study of RPN in animals as models for the disease in human beings is limited by several factors, including anatomical differences between human beings and most animal species as well as technical difficulties in studying the renal papilla. (+info)Glomerular lesions in experimental renal papillary necrosis. I. Ultrastructural aspects and some pathogenic considerations. (6/56)
Papillary necrosis was induced in rats by a single intravenous injection of bromoethylamine hydrobromide (BEA). From 7 days on glomerular lesions were recognized. They consisted of electron dense deposits mainly subepithelial in location; mild mesangial hypercellularity and matrix increase. Immunofluorescence with anti-rat gammaglobulin was positive, showing granular fluorescence in relation with basement membrane and mesangium. The possibility is raised that these lesions are due to the pathogenic action of immune complexes, the antigen being one arising during the necrosis of the renal papilla. It is also suggested that this mechanism can be operative in ths human being in cases of papillary necrosis of the kidney. (+info)Experimental renal papillary necrosis in the Mongolian gerbil (Meriones unguiculatus). (7/56)
Sequential light microscopic and ultrastructural examination of kidneys from male and light microscopic examination of female Mongolian gerbils given 250 mg 2-bromoethylamine hydrobromide (BEA)/kg body weight ip were performed. In addition, male Mongolian gerbils were treated with both BEA and ip injections of either water, dimethyl sulfoxide, piperonyl butoxide, or reserpine. Light microscopic renal lesions in male Mongolian gerbils progressed from congestion of the vasa recta of the proximal inner medulla at 6 hr post-treatment to total renal papillary necrosis (RPN) at 24 hr post-treatment. There was no sex difference in sensitivity to BEA. Ultrastructural alterations in male gerbils were restricted to the vasa recta. Vascular lesions of endothelial swelling and pericapillary edema in the vasa recta of the proximal inner medulla was observed 2 hr post-treatment and progressed to occlusion by platelets adherent to exposed basement membranes at 6 hr post-treatment. Diuresis induced by injections of saline and injections of dimethyl sulfoxide or piperonyl butoxide did not affect the development of BEA-induced RPN. Reserpine slowed the development of BEA-induced RPN by its vasodilatory effect on the renal vasculature, not by blocking the endothelial toxicity of BEA. RPN induced by BEA in the Mongolian gerbil is apparently an ischemic necrosis of the inner medulla that develops secondary to endothelial damage of the vasa recta. (+info)PHENACETIN NEPHROPATHY. (8/56)
Four patients who had ingested large amounts of phenacetin-salicylate medications were studied during a 12-month period. Renal failure had progressed slowly over a number of years. All patients took the drug because of psychogenic headache. Considerable skill was required to elicit the history of drug habituation. The major features of the nephropathy were multiple episodes of metabolic acidosis, minimal proteinuria, pyuria but no bacteriuria, and polyuria and polydipsia early in the course of drug ingestion. Papillary necrosis was not a prominent clinical feature of this series. Discontinuation of drug ingestion by one patient was associated with recovery of a considerable degree of renal function. Preliminary experimental evidence obtained in the dog suggests that salicylate impaired the efficiency of the counter-current multiplier by decreasing sodium transport in the ascending limb of Henle, and decreased the permeability to water of the distal convoluted and collecting tubule; phenacetin had no such effect. (+info)Kidney papillary necrosis is a medical condition characterized by the death (necrosis) of the renal papillae, which are the small conical projections at the ends of the renal tubules in the kidneys. This condition typically occurs due to reduced blood flow to the kidneys or as a result of toxic injury from certain medications, chronic infections, diabetes, sickle cell disease, and systemic vasculitides.
The necrosis of the papillae can lead to the formation of small stones or debris that can obstruct the flow of urine, causing further damage to the kidneys. Symptoms of kidney papillary necrosis may include fever, flank pain, nausea, vomiting, and bloody or foul-smelling urine. The diagnosis is typically made through imaging studies such as CT scans or MRI, and treatment may involve addressing the underlying cause, administering antibiotics to prevent infection, and providing supportive care to maintain kidney function.
Ethylamines are organic compounds that contain a primary amino group (-NH2) attached to an ethyl group (-C2H5). In other words, they have the formula R-CH2-CH2-NH2, where R is a carbon-containing group. Ethylamines are derivatives of ammonia (NH3), in which one or more hydrogen atoms have been replaced by an ethyl group.
Ethylamines can be found in various natural and synthetic substances. They are used as building blocks in the synthesis of various pharmaceuticals, agrochemicals, and other industrial chemicals. Some ethylamines also have psychoactive properties and are used as recreational drugs or abused for their mind-altering effects.
It is important to note that some ethylamines can be toxic or harmful to human health, especially at high concentrations or with prolonged exposure. Therefore, they should be handled with care and used only under controlled conditions.
Phenacetin is not typically defined in a medical dictionary as it is an obsolete drug. However, it was previously used as a painkiller and fever reducer. It is a compound that has been used in various forms of medication, such as headache powders and cough medicines. Phenacetin is no longer widely available or recommended for use due to its association with kidney damage and increased risk of cancer when taken in high doses or over long periods of time.
In modern medical contexts, phenacetin may be mentioned as a component of some older medications or as a historical example in discussions of the evolution of pharmaceuticals and their regulation.
Bromine is a chemical element with the symbol "Br" and atomic number 35. It belongs to the halogen group in the periodic table and is a volatile, reddish-brown liquid at room temperature that evaporates easily into a red-brown gas with a strong, chlorine-like odor.
Bromine is not found free in nature, but it is present in many minerals, such as bromite and halite. It is produced industrially through the treatment of brine with chlorine gas. Bromine has a wide range of uses, including as a disinfectant, fumigant, flame retardant, and intermediate in the production of various chemicals.
In medicine, bromine compounds have been used historically as sedatives and anticonvulsants, although their use has declined due to the availability of safer and more effective drugs. Bromine itself is not used medically, but some of its compounds may have therapeutic applications in certain contexts. For example, bromide salts have been used as a mild sedative and anticonvulsant in veterinary medicine. However, their use in humans is limited due to the risk of toxicity.
Kidney cortex necrosis is a serious condition characterized by the death (necrosis) of cells in the outer part (cortex) of the kidneys, usually as a result of an interruption in blood flow. This can occur due to various reasons such as severe shock, blood clots, or complications from pregnancy. The necrosis of kidney cortical tissue can lead to acute renal failure, which is a life-threatening situation requiring immediate medical attention and intensive care.
The death of kidney cells in the cortex disrupts the normal functioning of the kidneys, impairing their ability to filter waste products and excess fluids from the blood. This can result in the accumulation of harmful substances in the body and an imbalance of electrolytes, which can be life-threatening if left untreated.
Kidney cortex necrosis is typically diagnosed through a combination of clinical evaluation, laboratory tests, and imaging studies such as ultrasound or CT scan. Treatment usually involves supportive care, including dialysis to replace the kidneys' function until they can recover on their own or until a transplant can be performed. In some cases, the damage to the kidneys may be permanent, leading to chronic renal failure and the need for long-term dialysis or transplantation.
Fenamates is a term used to refer to a group of non-steroidal anti-inflammatory drugs (NSAIDs) that have a chemical structure related to fenamic acid. This group includes medications such as mefenamic acid, flufenamic acid, and tolfenamic acid, among others.
Fenamates are used to relieve pain, reduce inflammation, and lower fever. They work by inhibiting the activity of cyclooxygenase (COX) enzymes, which play a key role in the production of prostaglandins, hormone-like substances that mediate various physiological processes, including inflammation and pain perception.
Like other NSAIDs, fenamates can cause gastrointestinal side effects such as stomach ulcers, bleeding, and perforation, especially when taken in high doses or for prolonged periods. They may also increase the risk of cardiovascular events such as heart attack and stroke, particularly in people with pre-existing cardiovascular disease or other risk factors.
It is important to use fenamates only under the supervision of a healthcare provider and to follow their dosage instructions carefully to minimize the risk of adverse effects.
A kidney, in medical terms, is one of two bean-shaped organs located in the lower back region of the body. They are essential for maintaining homeostasis within the body by performing several crucial functions such as:
1. Regulation of water and electrolyte balance: Kidneys help regulate the amount of water and various electrolytes like sodium, potassium, and calcium in the bloodstream to maintain a stable internal environment.
2. Excretion of waste products: They filter waste products from the blood, including urea (a byproduct of protein metabolism), creatinine (a breakdown product of muscle tissue), and other harmful substances that result from normal cellular functions or external sources like medications and toxins.
3. Endocrine function: Kidneys produce several hormones with important roles in the body, such as erythropoietin (stimulates red blood cell production), renin (regulates blood pressure), and calcitriol (activated form of vitamin D that helps regulate calcium homeostasis).
4. pH balance regulation: Kidneys maintain the proper acid-base balance in the body by excreting either hydrogen ions or bicarbonate ions, depending on whether the blood is too acidic or too alkaline.
5. Blood pressure control: The kidneys play a significant role in regulating blood pressure through the renin-angiotensin-aldosterone system (RAAS), which constricts blood vessels and promotes sodium and water retention to increase blood volume and, consequently, blood pressure.
Anatomically, each kidney is approximately 10-12 cm long, 5-7 cm wide, and 3 cm thick, with a weight of about 120-170 grams. They are surrounded by a protective layer of fat and connected to the urinary system through the renal pelvis, ureters, bladder, and urethra.
The kidney medulla is the inner portion of the renal pyramids in the kidney, consisting of multiple conical structures found within the kidney. It is composed of loops of Henle and collecting ducts responsible for concentrating urine by reabsorbing water and producing a hyperosmotic environment. The kidney medulla has a unique blood supply and is divided into an inner and outer zone, with the inner zone having a higher osmolarity than the outer zone. This region of the kidney helps regulate electrolyte and fluid balance in the body.
Water deprivation is a condition that occurs when an individual is deliberately or unintentionally not given access to adequate water for a prolonged period. This can lead to dehydration, which is the excessive loss of body water and electrolytes. In severe cases, water deprivation can result in serious health complications, including seizures, kidney damage, brain damage, coma, and even death. It's important to note that water is essential for many bodily functions, including maintaining blood pressure, regulating body temperature, and removing waste products from the body. Therefore, it's crucial to stay hydrated by drinking an adequate amount of water each day.
