Novel and versatile reactions of trifluoroamine oxide: a new route to polyfluorinated ethers.

A series of pyrimidine methyl and polyfluoroalkyl ethers were synthesized from the reactions of trifluoroamine oxide (1) with several 5-substituted uracils in the presence of tetrabutylammonium hydroxide and methanol, 2,2,2-trifluoroethanol (6), or 1H,1H-pentafluoropropanol (7). With 5-(trifluoromethyl)uracil (2), the new ethers formed were 5-fluoro-5-(trifluoromethyl)-6-methoxypyrimidine-2,4-dione (8), 5-fluoro-5-(trifluoromethyl)-6-(trifluoroethoxy)pyrimidine-2,4-dione (9), and 5-fluoro-5-(trifluoromethyl)-6-(1H,1H- pentafluoropropoxy)pyrimidine-2,4-dione (10). With 5-chlorouracil (3), the new ethers 5-chloro-5-fluoro-6-methoxypyrimidine-2,4-dione (11), 5-chloro-5-fluoro-6-(trifluoroethoxy)pyrimidine-2,4-dione (12), and 5-chloro-5-fluoro-6-(1H,1H-pentafluoropropoxy)pyrimidine-2,4-dione (13) were obtained.

Anti-inflammatory and anti-arthritic activities of silymarin acting through inhibition of 5-lipoxygenase.

Silymarin, a mixture of flavonolignans, comprised mainly of three isomers, silybin, silydianin and silychristin isolated from the fruits of Silybum marianum, is currently in therapeutic use as a hepatoprotective agent. Silymarin on evaluation exhibited significant antiinflammatory and antiarthritic activities in the papaya latex induced model of inflammation and mycobacterial adjuvant induced arthritis in rats. Results of the study indicate its action through inhibition of 5-lipoxygenase for antiinflammatory and antiarthritic activities.

Candida overgrowth after treatment of duodenal ulcer. A comparison of cimetidine, famotidine, and omeprazole.

Acid-reducing drugs can cause increased growth of microbes, including fungus, because of high gastric pH. Our purpose was to evaluate the occurrence of mycotic infection in patients with duodenal ulcer on anti-ulcer therapy and to compare the effects of cimetidine, famotidine, and omeprazole. Eighty patients with duodenal ulcer (62 males and 18 female patients, 16-65 years old) were evaluated for mycotic infection before and after 6 weeks of therapy (cimetidine, 20 patients; famotidine, 40 patients; omeprazole, 20 patients).

Fractionation, analysis and diagnostic utility of Mycobacterium tuberculosis H37Ra excretory-secretory antigen in pulmonary tuberculosis.

Excretory-secretory antigen of Mycobacterium tuberculosis H37Ra (Mtb ES antigen) isolated from culture filtrate was partially purified by 6% trichloroacetic acid precipitation. The TCA supernatant fraction (Mtb EST antigen) was examined for its diagnostic use in the detection of tuberculous IgG antibody in human sera by stick Indirect ELISA. Using Mtb EST antigen, tuberculous IgG antibody was detected in 90% of smear positive and 71% of smear negative pulmonary tuberculosis cases and 10% of healthy and disease controls.

Application of papaya latex-induced rat paw inflammation: model for evaluation of slowly acting antiarthritic drugs.

Papaya latex-induced rat paw inflammation model for evaluating antiinflammatory activity has been developed and reported earlier. A number of drugs viz. aspirin, indomethacin, piroxicam, ibuprofen, prednisolone, levamisole, chloroquine, and boswellic acids showed antiinflammatory activity in this model.

Different antigen preparations, viz. excretory-secretory antigen (ES Ag), phosphate buffer saline soluble antigen (PBS-S Ag) and sodium dodecyl sulphate soluble antigen (SDS-S Ag) of M. tuberculosis (M.

Regulation of interrenal secretion in the axolotl, Ambystoma mexicanum.

The regulation of corticosteroid secretion of the adrenal cortex (interrenal tissue) of axolotl (Ambystoma mexicanum) was studied using in vitro preparations of kidney containing interrenal tissue. Normally, 0.3-0.

The prevalence of hypertension in rural population around Sevagram.

To detect the prevalence of hypertension in an asymptomatic rural community from Central India, we screened 4045 subjects (2247 men and 1798 women) aged 20 and beyond. The prevalence of hypertension was 34.12 per thousand population, being higher in women (40.

M-mode echocardiographic diagnosis of left ventricular hypertrophy.

To assess the utility of various primary and derived M-Mode Echocardiographic parameters for the purpose of defining left ventricular hypertrophy (LVH), 74 subjects with LVH were subjected to M-mode echocardiographic examination. It was concluded that except for cross sectional area, the other echocardiographic parameters performed too poorly to be of any clinical utility for defining LVH by echocardiography.

False positive ECG and coronary heart disease.

In 1983, we carried out a cross-sectional, rural community based study and highlighted an abysmally low prevalence of probable coronary heart disease in resting electrocardiogram. A seven year follow-up (1983-1990) of 179 suspects showed no morbidity or mortality from coronary heart disease. Eighty one out of 98 suspects tested negative on a symptom limited maximal exercise test.

The analysed data include age, sex, cause of burn and mortality in relation to age, cause and extent of burn injuries. Additional information with regard to socioeconomic status, marital status, place of burn, family size, type of burn, time of accident and time between injury and hospital admission was obtained from analysis of 271 of the 629 patients admitted between January 1990 and August 1990.

Evaluation of clinical variables as predicators of left ventricular function in acute myocardial infarction.

In 43 rural patients, all survivors of acute Myocardial infarction, left ventricular function was studied by 2-D echocardiography and evaluated in relation to 18 clinical predictors of left ventricular function. The mean left ventricular ejection fraction (LVEF) was 41.53 +/- 12.

Left ventricular M-mode echocardiographic measurements of Indian population.

The left ventricular dimensions of 506 normal healthy subjects (men = 317, women = 189) in the age group of 17 to 80 years were measured echocardiographically. The measurements were found to differ significantly from the western data. A separate limit for left ventricular echocardiographic parameter for the normal Indian population was established.

Neuropsychiatric disorders and periodontal disease.

The purpose of this study was to compare the severity of periodontal disease among subjects with neuropsychiatric disorders with that of a control group of normal subjects in order to determine the association between emotional disturbances and periodontal disease. One hundred and sixty-three subjects hospitalized for neuropsychiatric conditions (NP) and 78 control subjects with no emotional problems were examined. Periodontal attachment loss was measured using Russell's index (PI), and the oral hygiene status was evaluated with the Oral Hygiene Index (OHI) of Green and Vermillion by a single examiner.

Isoniazid induced neuropathy in slow versus rapid acetylators: an electrophysiological study.

Clinical, biochemical and nerve conduction studies were performed in 100 cases of tuberculosis taking isonicotinic acid hydrozide (isoniazid) for more than 12 weeks. Electro-physiological studies were carried out in a similar number of normal age and sex matched controls. In 16 percent of cases an abnormality was documented in the motor nerve conduction velocity, amplitude and terminal latency of the common peroneal, ulnar and median nerves; of these, only two patients had objective evidence of neuritis.

Left ventricular muscle mass by echocardiography: methodology.

The limitations of electrocardiography for diagnosing left ventricular hypertrophy (LVH), due to unacceptable accuracy and lack of serial quantifications, are well known. The use of angiocardiography for LVH assessment is invasive, hazardous and costly. Echocardiography provides an excellent method of estimation of left ventricular muscle mass, which is simple, non-hazardous, accurate and reproducible.

Left ventricular mass by M-mode echocardiography.

A comparison of various M-mode echocardiographic methods for assessment of left ventricular mass (LVM) was done in 21 subjects. The anatomical LVM was taken as Standard; it varied from 64.55 to 341.
