Characterization of the analgesic and anti-inflammatory activities of ketorolac and its enantiomers in the rat. (1/1272)

The marked analgesic efficacy of ketorolac in humans, relative to other nonsteroidal anti-inflammatory drugs (NSAIDs), has lead to speculation as to whether additional non-NSAID mechanism(s) contribute to its analgesic actions. To evaluate this possibility, we characterized (R,S)-ketorolac's pharmacological properties in vivo and in vitro using the nonselective cyclooxygenase (COX) inhibitors [indomethacin (INDO) and diclofenac sodium (DS)] as well as the selective COX-2 inhibitor, celecoxib, as references. The potency of racemic (R,S)-ketorolac was similar in tests of acetic acid-induced writhing, carrageenan-induced paw hyperalgesia, and carrageenan-induced edema formation in rats; ID50 values = 0.24, 0. 29, and 0.08 mg/kg, respectively. (R,S)-ketorolac's actions were stereospecific, with (S)-ketorolac possessing the biological activity of the racemate in the above tests. The analgesic potencies for (R,S)-, (S)-, and (R)-ketorolac, INDO, and DS were highly correlated with their anti-inflammatory potencies, suggesting a common mechanism. (R,S)-ketorolac was significantly more potent than INDO or DS in vivo. Neither difference in relative potency of COX inhibition for (R,S)-ketorolac over INDO and DS nor activity of (S)-ketorolac at a number of other enzymes, channels, or receptors could account for the differences in observed potency. The distribution coefficient for (R,S)-ketorolac was approximately 30-fold less than for DS or INDO, indicating that (R,S)-ketorolac is much less lipophilic than these NSAIDs. Therefore, the physicochemical and pharmacokinetics properties of (R,S)-ketorolac may optimize the concentrations of (S)-ketorolac at its biological target(s), resulting in greater efficacy and potency in vivo.  (+info)

A new rapid technique for the fixation of thyroid gland surgical specimens. (2/1272)

One of the main diagnostic problems in thyroid pathology is to distinguish between follicular adenoma and follicular carcinoma. Thorough sampling of the nodule's capsule is recommended in order to identify capsular invasion. However, during the hardening of the tissue, by the usual fixatives the capsule shrinks and rolls downwards and sometimes the capsule separates from the remaining tissue. The present work evaluates the use of "Lymph Node Revealing Solution" (LNRS) for the rapid fixation (2h) of different thyroid lesions as compared to that of formalin. Fifty-one unselected consecutive cases of thyroid nodules, which included various benign and malignant lesions, were examined. Each specimen was cut in two equal parts; one was fixed in LNRS, the other in formalin. Fixation in LNRS for 2 hours gave adequate results in sectioning and staining of the tissue, and excellent immunostains. Its advantage over formalin is the conservation of the natural relationship between the capsule and the rest of the tissue, on the same plane, as well as the short time required for the final diagnosis.  (+info)

Antinociceptive properties of the new alkaloid, cis-8, 10-di-N-propyllobelidiol hydrochloride dihydrate isolated from Siphocampylus verticillatus: evidence for the mechanism of action. (3/1272)

The antinociceptive action of the alkaloid cis-8, 10-di-n-propyllobelidiol hydrochloride dehydrate (DPHD), isolated from Siphocampylus verticillatus, given i.p., p.o., i.t., or i.c.v., was assessed in chemical and thermal models of nociception in mice, such as acetic acid-induced abdominal constriction, formalin- and capsaicin-induced licking, and hot-plate and tail-flick tests. DPHD given by i.p., p.o., i.t., or i.c.v. elicited significant and dose-related antinociception. At the ID50 level, DPHD was about 2- to 39-fold more potent than aspirin and dipyrone, but it was about 14- to 119-fold less potent than morphine. Its analgesic action was reversed by treatment of animals with p-chlorophenylalanine, naloxone, cyprodime, naltrindole, nor-binaltrorphimine, L-arginine, or pertussis toxin. Its action was also modulated by adrenal-gland hormones but was not affected by gamma-aminobutyric acid type A or type B antagonist, bicuculine, or phaclofen, nor was it affected by glibenclamide. DPHD, given daily for up to 7 days, did not develop tolerance to itself nor did it induce cross-tolerance to morphine. However, animals rendered tolerant to morphine presented cross-tolerance to DPHD. The antinociception of DPHD was not secondary to its anti-inflammatory effect, nor was it associated with nonspecific effects such as muscle relaxation or sedation. DPHD, in contrast to morphine, did not decrease charcoal meal transit in mice, nor did it inhibit electrical field stimulation of the guinea pig ileum or mouse vas deferens in vitro. Thus, DPHD produces dose-dependent and pronounced systemic, spinal, and supraspinal antinociception in mice, including against the neurogenic nociception induced by formalin and capsaicin. Its antinociceptive effect involves multiple mechanisms of action, namely interaction with mu, delta, or kappa opioid systems, L-arginine-nitric oxide and serotonin pathways, activation of Gi protein sensitive to pertussis toxin, and modulation by endogenous glucocorticoids.  (+info)

Immediate-early gene expression in the inferior mesenteric ganglion and colonic myenteric plexus of the guinea pig. (4/1272)

Activation of neurons in the inferior mesenteric ganglion (IMG) was assessed using c-fos, JunB, and c-Jun expression in the guinea pig IMG and colonic myenteric plexus during mechanosensory stimulation and acute colitis in normal and capsaicin-treated animals. Intracolonic saline or 2% acetic acid was administered, and mechanosensory stimulation was performed by passage of a small (0.5 cm) balloon either 4 or 24 hr later. Lower doses of capsaicin or vehicle were used to activate primary afferent fibers during balloon passage. c-Jun did not respond to any of the stimuli in the study. c-fos and JunB were absent from the IMG and myenteric plexus of untreated and saline-treated animals. Acetic acid induced acute colitis by 4 hr, which persisted for 24 hr, but c-fos was found only in enteric glia in the myenteric plexus and was absent from the IMG. Balloon passage induced c-fos and JunB in only a small subset of IMG neurons and no myenteric neurons. However, balloon passage induced c-fos and JunB in IMG neurons (notably those containing somatostatin) and the myenteric plexus of acetic acid-treated animals. After capsaicin treatment, c-fos and JunB induction by balloon passage was inhibited in the IMG, but there was enhanced c-fos expression in the myenteric plexus. c-fos and JunB induction by balloon stimulation was also mimicked by acute activation of capsaicin-sensitive nerves. These data suggest that colitis enhances reflex activity of the IMG by a mechanism that involves activation of both primary afferent fibers and the myenteric plexus.  (+info)

Short-chain fatty acids suppress cholesterol synthesis in rat liver and intestine. (5/1272)

We previously showed that plasma cholesterol levels decreased following ingestion of a short-chain fatty acid (SCFA) mixture composed of sodium salts of acetic, propionic, and butyric acids simulating cecal fermentation products of sugar-beet fiber (SBF). In the present study, we investigated whether hepatic and small intestinal cholesterol synthesis is involved in the cholesterol-lowering effects of SCFA and SBF. In vitro (expt. 1) and in vivo (expt. 2) cholesterol synthesis rates and the diurnal pattern of SCFA concentrations in portal plasma (expt. 3) were studied in three separate experiments in rats fed diets containing the SCFA mixture, SBF (100 g/kg diet), or the fiber-free control diet. Cholesterol synthesis was measured using 3H2O as a tracer. The in vitro rate of cholesterol synthesis, measured using liver slices, was greater in the SBF group, but not in the SCFA group, than in the fiber-free control group. In contrast, the hepatic cholesterol synthesis rate in vivo was lower in the SCFA group, but not in the SBF group, than in the control group. The mucosal cholesterol synthesis rate for the whole small intestine was <50% of the hepatic rate. The rate in the proximal region was slightly but significantly lower in the SCFA group, and was significantly higher in the SBF group than in the fiber-free group. The rate in the distal small intestines was also significantly greater in the SBF group than in the fiber-free group. Plasma total cholesterol concentrations were lower in the SCFA and SBF groups than in the fiber-free group in both experiments 2 and 3. Diurnal changes in portal SCFA and cholesterol levels were studied in the experiment 3. SCFA concentrations increased rapidly after the start of feeding the SCFA diet, and changes in plasma cholesterol were the reciprocal of those observed in SCFA. These results show that a decrease in hepatic cholesterol synthesis rate mainly contributes to the lowering of plasma cholesterol in rats fed the SCFA mixture diet. Changes in portal SCFA and cholesterol concentrations support this conclusion. In SBF-fed rats, SCFA produced by cecal fermentation are possibly involved in lowering plasma cholesterol levels by negating the counteractive induction of hepatic cholesterol synthesis caused by an increase in bile acid excretion.  (+info)

Interactions between carbon and nitrogen metabolism in Fibrobacter succinogenes S85: a 1H and 13C nuclear magnetic resonance and enzymatic study. (6/1272)

The effect of the presence of ammonia on [1-13C]glucose metabolism in the rumen fibrolytic bacterium Fibrobacter succinogenes S85 was studied by 13C and 1H nuclear magnetic resonance (NMR). Ammonia halved the level of glycogen storage and increased the rate of glucose conversion into acetate and succinate 2.2-fold and 1.4-fold, respectively, reducing the succinate-to-acetate ratio. The 13C enrichment of succinate and acetate was precisely quantified by 13C-filtered spin-echo difference 1H-NMR spectroscopy. The presence of ammonia did not modify the 13C enrichment of succinate C-2 (without ammonia, 20.8%, and with ammonia, 21.6%), indicating that the isotopic dilution of metabolites due to utilization of endogenous glycogen was not affected. In contrast, the presence of ammonia markedly decreased the 13C enrichment of acetate C-2 (from 40 to 31%), reflecting enhanced reversal of the succinate synthesis pathway. The reversal of glycolysis was unaffected by the presence of ammonia as shown by 13C-NMR analysis. Study of cell extracts showed that the main pathways of ammonia assimilation in F. succinogenes were glutamate dehydrogenase and alanine dehydrogenase. Glutamine synthetase activity was not detected. Glutamate dehydrogenase was active with both NAD and NADP as cofactors and was not repressed under ammonia limitation in the culture. Glutamate-pyruvate and glutamate-oxaloacetate transaminase activities were evidenced by spectrophotometry and 1H NMR. When cells were incubated in vivo with [1-13C]glucose, only 13C-labeled aspartate, glutamate, alanine, and valine were detected. Their labelings were consistent with the proposed amino acid synthesis pathway and with the reversal of the succinate synthesis pathway.  (+info)

Healing effects of heparin on acetic acid-induced gastric ulcers in rats. (7/1272)

OBJECTIVE: To investigate whether or not heparin can accelerate the healing process of acetic acid-induced gastric ulcers in rats and to identify the mechanisms for heparin to produce this effect, so that we can develop a new therapeutic application to heparin besides its traditional anticoagulant activity. METHODS: Male Sprague-Dawley rats were used to produce acetic acid-induced gastric ulcers. Heparin in the doses of 100, 500, and 1000 U/kg were administered intravenously through the tail vein once daily, starting 1 day after ulcer induction for 7 days in the dose-response experiment or heparin 1000 U/kg at a time schedule of 3, 5, and 7 days in the time-response study, respectively. The gastric mucosal blood flow (GMBF) was measured using a laser Doppler flowmeter under ether anesthesia. The rats were then sacrificed and the ulcer areas were measured. The gastric mucosa was then scraped for the determinations of mucosal prostaglandin E2 (PGE2) level and myeloper-oxidase (MPO) activity. RESULTS: Heparin in the doses of 500 and 1000 U/kg accelerated the healing of acetic acid ulcers in a dose-dependent manner. The highest dose of heparin also reduced the ulcer areas in a time-dependent fashion. The effect was accompanied by an increase in gastric mucosal PGE2 levels. The same dose of heparin not only decreased the gastric mucosal MPO activity but also increased the GMBF in a time-related manner. CONCLUSIONS: Heparin with the doses used in the present study accelerated the healing of acetic acid-induced gastric ulcers in rats in a dose- and time-dependent manner, and this action was related to its effects to increase the levels of gastric mucosal PGE2 and GMBF as well as to decrease the gastric mucosal MPO activity.  (+info)

Experimental colitis increases blood-brain barrier permeability in rabbits. (8/1272)

Extraintestinal manifestations of inflammatory bowel disease are numerous. This study examined the effects of two models of acute colitis on cerebral blood flow (CBF) and permeability of the blood-brain barrier in rabbits. CBF (measured with radiolabeled microspheres), or the extraction ratio or permeability-surface area (PS) product of the blood-brain barrier to fluorescein and FITC-dextran, was measured 48 h after colitis induction with acetic acid (HAc) or trinitrobenzene sulfonic acid (TNBS). PS product for fluorescein increased (P < 0.05) in TNBS colitis (1.33 x 10(-5) +/- 0.52 x 10(-5) ml/s and 0.48 x 10(-5) +/- 0.13 x 10(-5) ml/s (mean +/- SE) for treated (n = 14) and untreated (n = 10) animals, respectively. PS product for the larger FITC-dextran was not different in TNBS colitis (0.24 x 10(-5) +/- 0.09 x 10(-5) ml/s, n = 7) compared with untreated controls (0.19 x 10(-5) +/- 0.04 x 10(-5) ml/s, n = 8). PS product for fluorescein increased (P < 0.01) in HAc colitis compared with vehicle (2.66 x 10(-5) +/- 1.46 x 10(-5) ml/s and 0.33 x 10(-5) +/- 0.05 x 10(-5) ml/s, respectively; n = 6 in each group). The extraction of fluorescein from the blood to the brain increased by 75% during TNBS colitis when compared with vehicle (P < 0.05). CBF and cerebrovascular resistance did not change from the untreated control after TNBS colitis. Our data suggest that, irrespective of induction method, acute colitis increases the permeability of the blood-brain barrier to small molecules without changing CBF.  (+info)

Vinegars are commonly used as food condiments and preservatives. Apple cider vinegar (ACV) is also used in the Ayurvedic pharmaceutical industry because of its medicinal properties. Since specifically selected starter cultures for commercial vinegar production are not readily available, apple juice supplemented with sugar is commonly inoculated with a microbiologically undefined culture obtained from the previous batch of ACV. The present work focuses on the isolation of yeasts and acetic acid bacteria from ACV and the preparation of a starter culture. ACV was produced in a bench scale bioreactor using a traditional fermentation process wherein an acetic acid concentration of 3.8% was obtained after three weeks. Several acetic acid bacteria (AAB) were isolated from ACV using selective media. Microscopy revealed the cultures to be gram negative to gram variable short rods. The growth pattern of the isolates on differential media and biochemical tests suggested the presence of Acetobacter and

Vinegar, from the French vin aigre (sour wine), is a flavoring agent in many cuisines. Vinegar can be made from numerous fermentable carbohydrates including fruits, grains, honey, wine, and even potatoes. Acetic acid is one product of the fermentation process and gives vinegar its sharp flavor and pungent odor. White distilled vinegars are generally 4%-7% acetic acid. Cider and wine vinegars are 5%-6% acetic acid. Acetic acid, however, is NOT synonymous with vinegar. Vinegar contains many other ingredients such as amino acids, mineral salts, and nonvolatile organic acids. The US Food and Drug Administration states that diluted acetic acid is not vinegar and should not be added to food products that would be expected to contain vinegar. Specialty vinegars are herbal or fruit vinegars. Herbal vinegars are wine or white distilled vinegars that can be seasoned with garlic, basil, tarragon, or other spices. Fruit varieties are wine and white vinegars sweetened with fruit or fruit juice. A popular ...

Carefully remove all cerumen and debris to allow acetic acid to contact infected surfaces directly. To promote continuous contact, insert a wick of cotton saturated with acetic acid into the ear canal; the wick may also be saturated after insertion. Instruct the patient to keep the wick in for at least 24 hours and to keep it moist by adding 3 to 5 drops of acetic acid every 4 to 6 hours. The wick may be removed after 24 hours but the patient should continue to instill 5 drops of acetic acid 3 or 4 times daily thereafter, for as long as indicated. In pediatric patients, 3 to 4 drops may be sufficient due to the smaller capacity of the ear canal.. ...
Since acetic acid inhibits the growth and fermentation ability of Saccharomyces cerevisiae, it is one of the practical hindrances to the efficient production of bioethanol from a lignocellulosic biomass. Although extensive information is available on yeast response to acetic acid stress, the involvement of endoplasmic reticulum (ER) and unfolded protein response (UPR) has not been addressed. We herein demonstrated that acetic acid causes ER stress and induces the UPR. The accumulation of misfolded proteins in the ER and activation of Ire1p and Hac1p, an ER-stress sensor and ER stress-responsive transcription factor, respectively, were induced by a treatment with acetic acid stress (| 0.2% v/v). Other monocarboxylic acids such as propionic acid and sorbic acid, but not lactic acid, also induced the UPR. Additionally, ire1∆ and hac1∆ cells were more sensitive to acetic acid than wild-type cells, indicating that activation of the Ire1p-Hac1p pathway is required for maximum tolerance to acetic acid.

Chinese black vinegar is an aged product made from rice, wheat, millet, sorghum, or a combination thereof. It has an inky black color and a complex, malty flavor. There is no fixed recipe, so some Chinese black vinegars may contain added sugar, spices, or caramel color. The most popular variety, Zhenjiang vinegar, originates in the city of Zhenjiang in Jiangsu Province, eastern China.[24] Shanxi mature vinegar is another popular type of Chinese vinegar that is made exclusively from sorghum and other grains. Nowadays in Shanxi province, there are still some traditional vinegar workshops producing handmade vinegar which is aged for at least five years with a high acidity. Only the vinegar made in Taiyuan and some counties in Jinzhong and aged for at least three years is considered authentic Shanxi mature vinegar according to the latest national standard. A somewhat lighter form of black vinegar, made from rice, is produced in Japan, where it is called kurozu. Rice vinegar is most popular in the ...
A typical distilled vinegar contains 95% of water and rest is acetic acid , minor constituents. All vinegar is derived from wine. I memorized from the messenger of Allah his saying : Leave that which makes you doubt for that which does not make you doubt. In light of the above general principles, the following is a list of Halal and Haram animals in the Hanafi School: (Both these lists of animals are not exclusive) Animals whose meat is Halal: 1. Apple Cider Vinegar: It is produced from unprocessed apple juice and vinegar retains its natural amber color and fruity flavor. I dont know about vinegar, but apple cider usually has some amount of alcohol in it. There is left over wine in the wine vinegar, we consider wine vinegar not a Halal vinegar. Vinegar can be produced from apples or grapes depending on the conditions of the formation of vinegar. All the other types of vinegar are considered Halal. As this was the alcohol/ material that was fermented to become vinegar. According to Hanafi ...

Previous studies on healthy people show that vinegar delays gastric emptying and lowers postprandial blood glucose and insulin levels. The aim of this study was to investigate the effect of apple cider vinegar on delayed gastric emptying rate on diabetes mellitus patients. Ten patients with type 1 diabetes and diabetic gastroparesis, including one patient who had undergone vagotomy, were included and completed the investigator blinded crossover trial. The gastric emptying rate (GER) was measured using standardized real-time ultrasonography. The GER was calculated as the percentage change in the antral cross-sectional area 15 and 90 minutes after ingestion of 300 g rice pudding and 200 ml water (GER1), or 300 g rice pudding and 200 ml water with 30 ml apple cider vinegar (GER2). The subjects drank 200 ml water daily before breakfast one week before the measurement of GER1. The same subjects drank 200 ml water with 30 ml vinegar daily before breakfast for two weeks before the measurement of GER2. The

Limited shelf life of meat products due to microbial spoilage is a major problem in meat industry as meat is a good source for growth of microorganisms. Therefore, preservation is essential. Thus, the present study was focused to determine the effect of acetic acid, lactic acid and trisodium phosphate on microbial quality of chicken cold cuts (chicken salami and chicken roll). Samples were randomly collected during the chilling step and treated as groups by immersion in lactic acid (2, 3, 4%), acetic acid (2, 2.5, 3%), trisodium phosphate (8, 10, 12%) for 20 seconds. Samples without any treatment served as the control. All treatments were vaccum packed and stored under chilled condition. Treatments were evaluated for colony forming units (CFU), yeast and molds and pH in 10th, 20th, 30th and 40th day of storage. Based on CFU counts for chicken salami samples on 40th day, acetic acid 2, 2.5, 3% treated samples showed 1.55×105 CFU/g, 1.31×105 CFU/g, 1.16×105 CFU/g, lactic acid 2, 3, 4% treated ...
There are two main elaboration processes to produce vinegar, as follows: (1) traditional methods encompassing the transformation of ethanol into acetic acid by static surface culture of acetic acid bacteria placed at the interface between the liquid and air; and (2) submerged culture methods involving the use of bioreactors with a continuous air flow, thus the conversion of alcohol into acetic acid is much faster and takes place in the air-liquid interfaces of the air bubbles. Early records from China, the Middle East, and Greece describe vinegar for medicinal purposes: as a digestive aid, an antibacterial balm to dress wounds, and treatment for cough. Upon opening, vinegar may start to develop a sort of slime called mother of vinegar that consists of acetic acid bacteria and cellulose. Although acetic acid bacteria are feared among oenologists because they spoil wine, they are the main agents in the production of vinegar. However, some of these ABM can be aged for more than three years and ...
My best guess is you are interpreting the statement inductive effect decreases as the length of alkyl group increases somewhat out of context.. So, lets compare formic acid to acetic acid. Formic acid has hydrogen bonded to the carbonyl, while acetic acid has a methyl group. The methyl group is inductively donating, and as a result acetic acid is less acidic than formic acid. $p_{Ka}$ difference of $1$ full unit.. So now, let us compare methyl acetic acid (a precise, but incorrect, alternate name for propanoic acid) to acetic acid. Methyl acetic acid has an inductive donating group at the $\ce{CH2}$ carbon. As such, we expect some donation, and a lower acidity for methyl acetic acid as compared to acetic acid. True, the donating group is one group removed from the acidic site, which means the effect of the methyl group on methyl acetic acids acidity is diminished as compared to an electron donating group directly attached to the carbonyl, so the acidity reduction will be smaller. $p_{Ka}$ ...

Apple Cider Vinegar (ACV) is gaining popularity these days as a wonder cure for diabetes, weight loss, heart disease and much more. The question however is - Is there science behind these claims or is it a classic case of excellent marketing?. Vinegar has been used as a medical therapy for thousands of years. Recorded vinegar history starts around 5000 BC when the Babylonians were using the fruit of the date palm to make wine and vinegar. Vinegar residues have been found in ancient Egyptian urns traced to 3000 BC. As well, recorded vinegar history in China starts from texts that date back to 1200 BC.. During biblical times, vinegar was used to flavour foods, as an energising drink, and as a medicine, and it is mentioned in both the old and new testaments.. In ancient Greece, around 400 BC, Hippocrates, the father of modern medicine, prescribed apple cider vinegar mixed with honey for a variety of ills, including coughs and colds..

White vinegar is often used as a household cleaning agent.[38] Because it is acidic, it can dissolve mineral deposits from glass, coffee makers, and other smooth surfaces.[39] For most uses, dilution with water is recommended for safety and to avoid damaging the surfaces being cleaned.. Vinegar is an excellent solvent for cleaning epoxy resin and hardener, even after the epoxy has begun to harden. Malt vinegar sprinkled onto crumpled newspaper is a traditional, and still-popular, method of cleaning grease-smeared windows and mirrors in the United Kingdom.[40] Vinegar can be used for polishing brass or bronze. Vinegar is widely known as an effective cleaner of stainless steel and glass.. Vinegar has been reputed to have strong antibacterial properties. One test by Good Housekeepings microbiologist found that 5% vinegar is 90% effective against mold and 99.9% effective against bacteria,[41] though another study showed that vinegar is less effective than Clorox and Lysol against poliovirus.[42] In ...

Biomass gasification-fermentation is a process that involves the partial oxidation of biomass to synthesis gas or syngas, primarily containing CO, CO2, and H2, which is then fermented to ethanol and other co-products. The advantage of gasification-fermentation over the saccharification-fermentation process is that gasification utilizes all lignocellulosic components (cellulose, lignin and hemicellulose) in the biomass, leading to a greater potential for ethanol production from the same quantity of biomass. Syngas fermentation using ?Alkalibaculum bacchi? a new alkaliphilic acetogen strain CP11 was studied in 250-mL bottles containing 100 mL of yeast extract medium at 37°C and pH 8.0. The new strain CP11 was able to convert CO and H2 present in modeled syngas (from bottled gases) and producer syngas (obtained from gasifying switchgrass) to ethanol and acetic acid. The modeled syngas was composed of 40% CO, 30% CO2, and 30% H2 (by volume). The producer gas was made of 13.4% CO, 16.4% CO2, 11.1% ...

Did you know that you could prevent or improve heart disease with just two teaspoons of our apple cider vinegar a day? Thats cheaper than any medication available on the market! But you dont just have to take our word for it. This fact has been proven by medical science over and over again.. One study showed that vinegar or acetic acid solution mixed with a normal diet in rats reduced their systolic blood pressure (thats the top number on the blood pressure reading) by up to 20mmHg! Vinegar lowered the activity of renin and aldosterone by up to 40% and 25% respectively. Renin and aldosterone are two hormones in the body that work to increase blood pressure. So, lowering their activity would enable better control of the disease.. Translating this to a human trial, a lower risk of fatal heart disease was reported in the Nurses Health Study, a study that involved thousands of people. This particular benefit was seen in nurses who consumed salads topped with oil and vinegar dressings regularly. ...

  • In the study group (HSIL, HPV positive), patients will be treated with intravaginal self-administrated vaginal gel Deflagyn containing 10.0 mg of highly dispersed silicon dioxide, 24.8 mg of citric acid, and 0.25 mg of selenium per administration (5 ml). (
  • The results show that as the mass fraction of acetic acid increases, the surface tension of the liquid phase decreases, and the viscosity first increases and then decreases. (
  • azoic dyes show color liquid alkali resistant agent, disperse dyes on polyester dyeing auxiliaries, weak acid dyes dyeing mulberry silk etc. (
  • Solid acetic acid has a higher density than its liquid form, therefore it sinks to the bottom when it meets the liquid Acetic Acid. (
  • Acetic acid is acolourless liquid with a pungent odour. (
  • Acetic Acid is an organic compound in the form of a colourless liquid. (
  • Carboxylic acid with general formula RCOOH are organic compound with a carboxyl (carbonyl+hydroxyl) functional group. (
  • In solid acetic acid, the molecules form chains, individual molecules being interconnected by hydrogen bonds. (
  • In this work, poplar was pretreated with acetic acid (AC) to produce xylooligosaccharides (XOS), and hydrogen peroxide-acetic acid (HPAC) was used to remove residual lignin in AC-pretreated poplar for enzymatic hydrolysis. (
  • In this work, XOS and monosaccharides were produced from poplar by a combination of AC and hydrogen-peroxide/acetic acid (HPAC) pretreatments and enzymatic hydrolysis. (
  • Respiratory symptoms in hospital cleaning staff exposed to a product containing hydrogen peroxide, peracetic acid, and acetic acid. (

  • Measurements have been made of the preferential uptake of acetic acid from aqueous solutions onto activated carbons and polymeric sorbents. (
  • It has been reported that in 12 workers exposed for two or more years to an average acetic acid airborne concentration of 51 ppm, there were symptoms of conjunctival irritation, upper respiratory tract irritation, and hyperkeratotic dermatitis. (
  • The acetic acid it contains is said to kill weeds, especially in the form of vinegar essence, which has a higher acid concentration than simple vinegar. (
  • With higher alkanes (starting with octane), acetic acid is not miscible at all compositions, and solubility of acetic acid in alkanes declines with longer n-alkanes. (
  • In the context of acid-base reactions, the abbreviation HAc is sometimes used, where Ac in this case is a symbol for acetate (rather than acetyl). (
  • Acetate is the ion resulting from loss of H+ from acetic acid. (
  • At physiological pHs, acetic acid is usually fully ionised to acetate. (
  • A salt, acylal of acetic acid is called acetate. (
