Esophageal tone in patients with total aperistalsis: gastroesophageal reflux disease versus achalasia. (1/25)

We have evaluated esophageal tone in two different conditions that, in some cases, similarly impair phasic esophageal motility. Studies were performed in 14 healthy volunteers, 10 patients with total esophageal aperistalsis secondary to gastroesophageal reflux disease (GERD), and 25 untreated achalasia patients. We quantified esophageal compliance and relaxation induced by a nitric oxide donor using a barostat. Intraesophageal volume at a minimal distending pressure (2 mmHg) was not significantly different among all three groups (4.1 +/- 0.7, 3.8 +/- 0.7, and 4.2 +/- 1.2 ml for healthy, GERD, and achalasia groups, respectively). Esophageal compliance was significantly increased (P < 0.05 vs. healthy group) in the two groups of patients with aperistalsis (1.9 +/- 0.2, 3.0 +/- 0.2, and 3.1 +/- 0.3 ml/mmHg for healthy, GERD, and achalasia groups, respectively). Esophageal relaxation was decreased in GERD patients (Delta diameter: 0.4 +/- 0.1 cm) and increased in achalasia patients (Delta diameter: 1.3 +/- 0.4 cm) relative to healthy subjects (Delta diameter: 0.9 +/- 0.2 cm) (P < 0.05 for GERD vs. achalasia and healthy groups). Our results indicate that diseases that similarly impair phasic esophageal motility may affect esophageal tone differently.  (+info)

Defective innervation of heart in diabetic autonomic neuropathy. (2/25)

Heart rate responses to autonomic stimulation and inhibition were studied in 13 diabetic autonomic neuropathy. Parasympathetic function was impaired in all patients and sympathetic function in most. One patient's heart appeared to be totally denervated. The consequences of cardiac denervation include tachycardia, a fixed heart rate, and a possible tendency to cardiac dysrhythmias, which caused spontaneous cardiac arrests in three patients.  (+info)

Adrenergic regulation of blood pressure in chronic renal failure. (3/25)

Previous investigations have suggested that significant hypotension during hemodialysis may result from abnormalities of sympathetic nervous system activity. To further evaluate these phenomena, plasma dopamine beta-hydroxylase (D beta H) and cold pressor test (proposed indexes of efferent sympathetic nervous system activity) and amyl nitrite inhalation (an index of the entire baroreceptor reflex arc) were studied in two groups of patients: group I, patients exhibiting a mean arterial pressure decrease to less than 70 mm Hg during less than 10% of dialyses; group II (hemodialysis hypotension), patients with a mean arterial pressure decrease to less than 70 mm Hg during more than 90% of dialyses. The groups were similar with respect to plasma renin activity, renin response to ultrafiltration, age, duration of dialysis, nerve conduction velocity, plasma protein concentration, hematocrit, dialysis weight change, resting heart rate, sex, race, blood pressure and heart rate response to cold pressor test, and 125I-albumin plasma volume. Supine mean arterial pressure was higher in patients with hemodialysis hypotension than in patients without hemodialysis hypotension (group I) both before and after dialysis. Plasma D beta H activity was significantly higher in patients with hemodialysis hypotension (group II) than in group I both before and after dialysis. Amyl nitrite inhalation, expressed as change in delta R-R interval/mean arterial pressure decrease, was less in hemodialysis hypotension patients. These results suggest that hemodialysis hypotension may result from a lesion in the baroreceptors, cardiopulmonary receptors, or visceral afferent nerves. Furthermore, elevated mean arterial pressure in patients with hemodialysis hypotension may be neurogenic in origin, as reflected by plasma D beta H activity, and appears similar to the hypertension that follows baroreceptor deafferentation of experimental animals.  (+info)

MUSCULAR SUBAORTIC STENOSIS: THE EFFECT OF PERIPHERAL VASODILATATION. (4/25)

Amyl nitrite was administered on two occasions to a patient with muscular subaortic stenosis, to ascertain if selective peripheral vasodilatation would affect the degree of obstruction to left ventricular outflow in this condition. On each occasion there was a marked increase in the systolic pressure gradient across the left ventricular outflow tract prior to the onset of reflex tachycardia. Following the second amyl nitrite inhalation, the systolic cross-sectional area of the left ventricular outflow tract decreased to 1.0 sq. cm., from the control value of 2.6 sq. cm. It is believed that the increased degree of muscular subaortic stenosis, following peripheral vasodilatation, could be secondary to a decrease in the systolic size of the whole left ventricle, or to a selective decrease in the physical size of the left ventricular outflow tract.  (+info)

Longitudinal patterns of methamphetamine, popper (amyl nitrite), and cocaine use and high-risk sexual behavior among a cohort of san francisco men who have sex with men. (5/25)

Most prior studies examining drug use among men who have sex with men (MSM) have been cross-sectional or retrospective and have not determined whether periods of increased drug use are associated with high-risk sexual behavior at the individual level. In this article, we describe patterns of use of methamphetamines, poppers, and sniffed cocaine and sexual risk behavior among 736 San Francisco MSM enrolled in the EXPLORE study and followed for up to 48 months. In longitudinal analysis, use of methamphetamines, poppers, and sniffed cocaine declined during follow-up. However, compared with older participants, younger participants were more likely to increase their drug use over time. Results of conditional logistic regression demonstrated that high-risk sexual behavior was more common during reporting periods characterized by increased methamphetamine, poppers, or sniffed cocaine use. This within-person analysis found that compared with periods of no drug use, periods of both light drug use (less than weekly use of drugs) and heavier drug use (at least weekly use of at least one drug) were significantly associated with increased risk of engaging in unprotected anal sex with an HIV-positive or unknown-status partner. These results suggest that even intermittent, recreational use of these drugs may lead to high-risk sexual behavior, and that, to reduce and prevent risks of HIV, no level of use of these drugs should be considered "safe." HIV prevention interventions should target MSM who report either light or heavy use of methamphetamines, poppers, and sniffed cocaine.  (+info)

Comparative effects of glyceryl trinitrate and amyl nitrite on pulse wave reflection and augmentation index. (6/25)

AIMS: The influence of vasodilators on augmentation index (AIx) offers a simple, rapid and noninvasive method of evaluating vascular function. Glyceryl trinitrate (GTN) is widely used as an endothelium-independent vasodilator, although other nitrates that are shorter acting may have advantages in clinical studies. The aim of this study was to compare the effects of two short-acting nitrates, GTN and amyl nitrite, which have differing pharmacodynamic profiles. METHODS: Twenty-one healthy volunteers (15 male; mean age 35 years, range 21-56 years) attended on three occasions and received sublingual GTN (0.5 mg for 3 min), inhaled amyl nitrite (0.2 ml inhaled for 30 s), or no treatment in a randomized cross-over design. Haemodynamic responses of AIx, blood pressure and thoracic bioimpedance (heart rate, cardiac index) were assessed by measurement at baseline, every 60 s for the first 5 min, and then every 5 min for a further 55 min. RESULTS: AIx was reduced by amyl nitrite (peak effect -9 +/- 2% at 1 min, P < 0.002) and GTN (peak effect -12 +/- 3% at 4 min, P < 0.05). Compared with amyl nitrite, the onset and offset of action of GTN was slower. Amyl nitrite initially increased heart rate by 27 +/- 4% (P < 0.001) and cardiac index by 13 +/- 3% (P < 0.001) whereas GTN had no significant effect (P > 0.05). Neither agent affected blood pressure. CONCLUSIONS: GTN causes a slower and more sustained reduction in AIx than amyl nitrite. Although amyl nitrite causes a more rapid fall and recovery in AIx, it induces a reflex tachycardia that may limit interpretation of the initial (1 min) but not later (2 min) changes in AIx. The prolonged offset of GTN suggests that a sufficient washout period must be included when making repeated measures or when assessing the subsequent effects of other agents.  (+info)

Substance use and sexual behaviours of Japanese men who have sex with men: a nationwide internet survey conducted in Japan. (8/25)

BACKGROUND: Japanese men who have sex with men (MSM), especially those living in large metropolitan areas such as Tokyo and Osaka, are facing a growing HIV/AIDS epidemic. Although the Internet is used as a new venue for meeting sex partners, it can also serve as a useful research tool for investigating the risk behaviours of Japanese MSM. This Internet survey explored the extent of substance use and its association with sexual risk behaviours among Japanese MSM. METHODS: Between 28 February 2003 and 16 May 2003 MSM were recruited through 57 Japanese gay-oriented Web sites, gay magazines, and Internet mailing lists. Participants completed a structured questionnaire anonymously through the Internet. RESULTS: In total, 2,062 Japanese MSM completed the questionnaire. The average age of participants was 29.0 years and 70.5% identified as gay, 20.8% as bisexual, and 8.7% as other. Overall, 34.5% reported never using a substance, 45% reported ever using one type of substance (lifetime reported single substance users), and 19.6% had used more than 1 type of substance (lifetime reported multiple substance users) in their lifetimes. The substances most commonly used were amyl nitrite (63.2%), 5-methoxy-N, N-diisopropyltryptamine (5MEO-DIPT) (9.3%), and marijuana (5.7%). In the multivariate analysis, unprotected anal intercourse, having had 6 or more sexual partners, visiting a sex club/gay venue in the previous 6 months, a lower education level, and being 30 to 39 years of age were associated with both lifetime single and lifetime multiple substance use. Lifetime reported multiple substance use was also correlated with having a casual sex partner, having symptoms of depression, being diagnosed as HIV-positive, and greater HIV/AIDS-related knowledge. CONCLUSION: This is the first Internet-based research focused on the sexual and substance use behaviours of MSM in Asia. Our findings suggest a compelling need for prevention interventions to reduce HIV risk-related substance use behaviours among Japanese MSM. The results also suggest that the Internet is potentially a useful tool for collecting behavioural data and promoting prevention interventions among this population.  (+info)

Amyl nitrite is very flammable. Do not use where it might become ignited. General - Tolerance to amyl nitrite may develop with repeated use of the drug for prolonged periods of time. Tolerance may be minimized by beginning with the smallest effective dose and alternating the drug with another coronary vasodilator. High doses of nitrites may produce methemoglobinemia, especially in individuals with methemoglobin reductase deficiency or other metabolic abnormality that interferes with the normal conversion of methemoglobin back to hemoglobin. Patient Information - Amyl nitrite should be taken by the patient when seated or lying down. Drug Interactions - Taking amyl nitrite after drinking alcohol may worsen side effects and may cause severe hypotension and cardiovascular collapse. Carcinogenesis, Mutagenesis, Fertility Impairment - Adequate long term studies to establish adverse carcinogenic potential of this drug have not been reported. Pregnancy - Teratogenic effects.

The hemodynamic effects of amyl nitrite inhalation were studied in 13 openchest, anesthetized dogs. In each animal, the right ventricle was bypassed. Blood was drained from the right atrium into a reservoir and pumped at fixed flow into the pulmonary circulation. Alterations in total vascular volume were calculated on the basis of changes in reservoir level. Following amyl nitrite inhalation, all animals exhibited decreased arteriolar resistance and eventually an increase in total vascular volume, These results indicate that amyl nitrite, like other nitrite compounds, dilates vascular smooth muscle and relaxes resistance and capacitance vessels ...

Twenty-one patients with muscular subaortic stenosis were treated with oral propranolol for periods of 6 to 34 months for a total of 42.5 patient years. The average follow-up was 2 years. Four patients with latent obstruction became asymptomatic on propranolol therapy. Of the 17 patients with resting obstruction, 7 improved, 2 were unchanged, 5 deteriorated, and 2 died during the period of treatment. The 7 patients with resting obstruction who are still improved on propranolol have had relatively short periods of treatment (average 15 months), and none experienced the degree of improvement that occurred in the patients with latent obstruction. This study indicates that propranolol is most effective in patients with muscular subaortic stenosis who have latent obstruction. It is of limited value in patients with resting obstruction because the benefit of propranolol therapy in the majority of these patients is eventually overtaken by progression in the disease. ...
Poppers are a street name for a group of chemicals better known as alkyl nitrites. They originally came into medicine in the form of amyl nitrite, which was discovered to have a potent capability to expand blood vessels. This feature found use in the treatment of angina pectoris, a particular kind of chest pain resulting from narrowing of the blood vessels of the heart.. Amyl nitrite remained a medicine, and in fact in many places available freely over the counter. In 1969, the US Food and Drug Administration made it prescription only[1] when the increased use of it in raves and gay sex aroused the attention of the government. However, other variants of the chemical group, including isobutyl nitrite, isopropyl nitrite, pentyl nitrite, and cyclohexyl nitrite, have a mixed legal status in different countries.. In the European Union, isobutyl nitrite remained most popular until it was banned in 2007[2] based on the European Chemicals Agency classifying it as a potential cancer-causing chemical. ...

AMYL ALCOHOLS (C5H11OH). Eight amyl alcohols are known: normal amyl alcohol CH3·(CH2)4·OH, isobutyl carbinol or isoamyl alcohol (CH3)2·CH·CH2·CH2OH, active amyl alcohol (CH3)(C2H5):CH·CH2OH, tertiary butyl carbinol(CH3)3C·CH2OH, diethyl carbinol (C2H5)2CH·OH, methyl (n) propyl carbinol (CH3·CH2·CH2) (CH3):CH:OH, methyl isopropyl carbinol (CH3)2:CH(CH3):CHOH, and dimethyl ethyl carbinol (CH3)2·(C2H5)⫶C·OH. Of these alcohols, the first four are primary, the last one a tertiary, the other three secondary alcohols; three of them, viz. active amyl alcohol, methyl (n) propyl carbinol, and methyl isopropyl carbinol, contain an asymmetric carbon atom and can consequently each exist in two optically active, and one optically inactive form.. The most important is isobutyl carbinol, this being the chief constituent of fermentation amyl alcohol, and consequently a constituent of fusel (q.v.) oil. It may be separated from fusel oil by shaking with strong brine solution, separating the oily ...
1. Although the high-frequency fluctuations in R-R interval (respiratory sinus arrhythmia) observed in heart transplant recipients are not a reliable marker of reinnervation because of a previously shown direct mechanical effect of breathing, the presence of a non-respiration-related low-frequency oscillation reflects rhythms generated outside the heart, and thus could be neurally mediated.. 2. To evaluate the presence of reinnervation, the spontaneous variability in R-R interval was investigated, supine and after passive tilting, in 23 heart transplant recipients (age 43 years, range 23-64 years) and in 25 normotensive control subjects by autoregressive spectral analysis of low- and high-frequency spontaneous fluctuations in R-R interval and respiration. The response of R-R interval to amyl nitrite inhalation was also evaluated in five heart transplant recipients and eight control subjects.. 3. Detectable low-frequency oscillations, unrelated to respiration, were present in 13/23 heart ...

There are problems with trying to modify ones NO status via diet, in general it doesnt work long term, at least not by any methods that have been tried. There is a non-dietary method I am working on, but it isnt generally accepted yet. Methods that dont work include so-called NO donors (such as nitroglycerine which isnt really an NO donor but it has some NO-donor-like properties and other organic nitrates) they cause what is called "nitrate resistance". Amyl nitrite does cause acute NO effects and is sometimes used as a sexual stimulant (don t confuse with amyl nitrate). Long term or chronic use would cause nitrate resistance. L-arginine causes "arginine resistance". This is thought to be due to generation of potent inhibitors of nitric oxide synthase by physiology, the various methyl arginines. The presence of these inhibitors is thought to explain why acute arginine does stimulate nitric oxide synthase but chronic arginine doesn t. NO physiology is extremely important and is extremely ...
Alkyl nitrites are a group of chemical compounds based upon the molecular structure R-ONO. Formally they are alkyl esters of nitrous acid. They are distinct from nitro compounds (R-NO2). The first few members of the series are volatile liquids; methyl nitrite and ethyl nitrite are gaseous at room temperature and pressure. The compounds have a distinctive fruity odor. Another frequently encountered nitrite is amyl nitrite (3-methylbutyl nitrite). Alkyl nitrites were initially, and largely still are used as medications and chemical reagents, a practice which began in the late 19th century. In their use as medicine, are often inhaled for relief of angina and other heart-related symptoms of disease. However, when referred to as "poppers", alkyl nitrites represent recreational drugs. ...
The incidents include abnormal heart rhythm atrial fibrillation and ventricular arrhythmialow blood pressure, myocardial infarction, and blood clots thromboembolism. Taking poppers amyl nitrite with sildenafil can have a dangerous effect on your heart. These additional blood pressure reductions were of a similar magnitude to those seen when sildenafil was administered alone to healthy volunteers see section 5. It interferes with the way the medicine works. How does sildenafil work? Some complementary therapies may have ingredients that could interfere with sildenafil and cause side effects. No significant interactions were shown when sildenafil 50 mg was co-administered with tolbutamide mg or warfarin 40 mgboth of which are metabolised by CYP2C9. Another thing to consider is that sexual activity is associated with a degree of cardiac risk. Sometimes, nitrates are also given on a daily basis, once or twice a day. The dosage for Cialis for once daily use may be increased to 5 mg if necessary. ...
Hydrogen sulfide, toxicity is comparable with that of Carbon Monoxide. Detoxification is effected by oxidation to Sulfate, which is harmless. Hence, low levels of Hydrogen Sulfide may be tolerated indefinitely. At some threshold level, believed to average around 300-350 ppm, the oxidative enzymes become overwhelmed. Eventually the gas is converted to sulfite in the mitochondria by Thiosulfate reductase, and the Dulfite is further oxidized to Thiosulfate and Sulfate by Sulfite Oxidase. The Sulfates are excreted in the urine. Diagnostic of extreme poisoning by H2S is the discolouration of copper coins in the pockets of the victim. Treatment involves immediate inhalation of Amyl Nitrite, injections of Sodium Nitrite, or administration of 4-dimethylaminophenol in combination with inhalation of pure Oxygen, administration of bronchodilators to overcome eventual bronchospasm, and in some cases hyperbaric Oxygen therapy. **Chronic exposure to low level H2S (around 2 ppm) has been implicated in ...
Kirby Institute, May 2016. The Flux Study, a study of drug use (and non-use) among gay and bisexual men, has recently released its first annual report.. Flux is a cohort study of 2251 men, including over 1700 who are being followed at 6-monthly intervals. It identifies: risk factors, prevalence, incidence, and associated harms of drug use; the role of gay community norms in individuals beliefs about drug use; and implications for HIV/HCV infection.. Some early key findings show that:. • Over three quarters (81.6%) have ever used illicit drugs, with half (50.5%) having done so in the previous six months.. • The most commonly and frequently used drugs were marijuana and amyl nitrite, but over a quarter (28.8%) had used any party drugs (including amphetamine-type stimulants and cocaine) in the previous six months.. • Men in the sample tended to express fairly negative opinions about illicit drug use within the gay community, although they tended to be less concerned about their own illicit ...
Baroreceptor activity and postural blood volume changes were evaluated in four normotensive and nine hypertensive uremic patients before and after bilateral nephrectomy. Baroreceptor activity, reflected by the slope of linear regression of R-R interval with drug-induced systolic blood pressure elevation, was significantly lower in hypertensive than in normotensive patients. Six of nine patients had normal blood pressure following bilateral nephrectomy; however, the mean slopes of all nine patients, irrespective of postnephrectomy blood pressure, approached that of normotensive uremic patients. The slopes of both normotensive and hypertensive patients, before and after bilateral nephrectomy, were significantly less than normal controls. Similar results were found in lowering blood pressure with amyl nitrite.. Depressed baroreceptor activity is suggested to be secondary to neuropathy of the autonomic nervous system, chronic hypertension, heart disease, and anemia. It is speculated that this ...
Treatment of cyanide toxicity should be initiated as soon as it is suspected; do not delay treatment while awaiting formal diagnosis by blood cyanide levels. Primarily, treatment is aimed at uncoupling cyanide from cytochrome oxidase, and allowing cells to return to aerobic metabolism via oxidative phosphorylation..

The family of drugs typified by MDMA produce their effects through multiple mechanisms of action in the body, and consequently produce three distinct cues which animals can be trained to respond to: a stimulant cue typified by drugs such as methamphetamine, a psychedelic cue typified by drugs such as LSD and DOM, and an "entactogen-like" cue which is produced by drugs such as MDAI and MBDB. These drugs cause drug-appropriate responses in animals trained to recognize the effects of MDMA, but do not produce responses in animals trained selectively to respond to stimulants or hallucinogens. Because these compounds selectively release serotonin in the brain but have little effect on dopamine or noradrenaline levels, they can produce empathogenic effects but without any stimulant action, instead being somewhat sedating.[4][5][6][7][8][9][10] Very high doses can be fatal in rats with a 50% fatality rate for those subcutaneously injected with 28 mg/kg of MDAI. This is a result of the way serotonin ...
The Black Welsh Mountain sheep is spread through most of the British Isles. Small populations are also found in Ireland, Canada and the United States. These are the only completely black-woolled English breed. The fleeces are popular with hand spinners and weavers. The pelts have a rich, deep pile and make wonderful floor rugs and seat covers.
Amyl nitrate poppers have a rich history in treating angina and it is also a treatment for cyanide poisoning. Their inhalation relaxes every smooth muscle, which includes the vagina, anus and the sphincter muscles. As a result, the blood vessels dilate and therefore a sudden blood pressure drop happens. Further, this increases the heart rate, produces a more sensation of heat and excitement which mostly last for a couple of minutes.. Amyl nitrate poppers usage is high in clubs and in enhancing sexual experience. The euphoria, head rush, uncontrolled laughter and giggling and many other sensations which result from the blood pressure drop increases sexual arousal and desire.. Furthermore, the relaxation of the sphincter muscle, the vagina and the anus can make penetration easier during sex. Some research shows that inhaling poppers before sex can increase the chances of getting an orgasm. The experience of poppers is universal as both men and women can benefit from it.. Using them. Most people ...

General Description of Poppers. They are categorized under amyl nitrates drugs. Other street names commonly used include Ram, TNT, liquid gold, thrust etc. Similar drugs include butyl nitrite and isobutyl nitrite.. These drugs originally came in form of capsules that popped open in a small glass bottle, hence the name poppers. However, today, they are likely to be packaged in small bottles too. They simply dilate blood vessels so that more blood can get into the heart. You could just sniff it from the bottle and it will give you a rush that lasts a couple of minutes.. How they are Special during Love-making. Many of us never want to go without them because they make this occasion special - sex. Not that they are addictive, but truth be told, the amyl nitrate element contained therein gives you the ultimate rush you want to experience during love-making..

Unloaded shortening velocity, a mechanical parameter associated with the rate of cross-bridge cycling, was investigated in chemically skinned guinea pig taenia coli and hog carotid artery. Shortening velocity was measured by the technique described by Edman, whereby large length steps are rapidly imposed on the muscle and the time under unloaded conditions is determined from the isometric myograms. Shortening velocity determined in this manner was similar to Vmax from the Hill force-velocity relations reported for both living and skinned taenia coli, and, in the case of carotid artery, was at least as large as that reported for living muscle. The behavior of shortening velocity was qualitatively similar for both preparations. Shortening velocity was strongly temperature dependent, with a Q10 of approximately 3.6. Shortening velocity was found to be dependent on both the Ca++ and calmodulin concentration. In contrast to the dependence of isometric force on Ca++-calmodulin, shortening velocity ...
Numerous studies have suggested that epinephrine may facilitate neural release of NE. There have been no studies in humans that demonstrate the functional significance of this action. To determine whether epinephrine facilitates neurogenic vasoconstriction in humans, we contrasted forearm vasoconstrictor responses to a reflex stimulus (lower body negative pressure [LBNP]) and to intraarterial NE before, during, and 30 min after infusion of epinephrine (50 ng/min) or isoproterenol (10 or 25 ng/min) into a brachial artery. These doses had no systemic effects. We reasoned that if prejunctional stimulation of beta receptors by epinephrine and isoproterenol had functional significance, the vasoconstrictor response to LBNP would be potentiated in comparison to the response to NE (postjunctional mechanism). Studies were done on 23 normal male volunteers. Forearm blood flow was measured with a strain gauge plethysmograph and intraarterial pressure was recorded. The ratio of vasoconstrictor responses to ...
Results -For the initial runs with the series of 12 ketones (NIOSH #1301), we were able to separate 10 of the components by just increasing the ramp rate from 10o/min to 200 /min. The final time for analysis was 11 minutes. We do have 8 ramp rates and 4 cooling fan rates so with an additional ramp, we should be able to separate methyl amyl ketone and ethyl amyl ketone and use a faster fan rate to reduce the cool down time. For NIOSH Method #1501, we were able to separate 15 of the 17 compounds in 14 minutes instead of 35 minutes. We were not able to separate nitrobenzene and naphthalene but there is a such a significant difference in the PID/FID response ratio that each of the components can be easily identified ...
Brandy and whiskey were listed as official drugs in the U. S. Pharmacopeia until the 1940s and ethanol was listed until 1975. Though brandy, whiskey, and neutral spirits can all be used as solvents, there is usually no designation on herbal extracts as to what type of alcohol is actually employed. Yet significant differences exist between them. The different congeners in each produce different flavors, aromas and effects of the distillate. These compounds vary depending upon what plant source was fermented. The main congeners are higher alcohols that make up what is called the fusel oil. These are more potent depressants and more toxic than an equal amount of ethanol. Alcohol distilled from potatoes has the highest amount of fusel oil which is almost pure amyl alcohol. Grain alcohol has more fusel oil than the alcohol distilled from grapes. The fusel oil from grains consists mostly of amyl alcohol while that from grapes has more butyl alcohol in addition to many volatile fatty acid congeners. ...

The Minto Album, in which A Mountain Sheep appeared, was one of several albums-comprising gilded, vividly colored portraits of emperors, courtiers, and religious figures as well as images of plant and animal life-created for the Mughal emperors Jahangir and Shah Jahan, who reigned between 1605 and 1658. The Persian term for these albums, muraqqa, refers to their patchwork construction: each folio is composed of several layers of paper pasted together to form a single, continuous sheet. Typically, each double-sided folio consisted of an image on one side and a panel of calligraphy on the other, each one surrounded by a lavish decorative border. The folios were then arranged within the album so that panels of calligraphy alternated with images ...
