Chemical analysis of the bronchoalveolar washing fluid in the diagnosis of liquid paraffin pneumonia

Abstract: Lipid analyses of the bronchoalveolar washing fluid of three patients affected with chronic unidentified pneumonia showed the presence of a major hydrophobic compound identified as paraffin oil by thin layer chromatography, infrared spectroscopy and gas liquid chromatography (by comparison with various paraffin preparations as standards). Moreover the phospholipid and neutral lipid composition was determined. In conclusion, the usefulness of bronchoalveolar lavage and its biochemical analysis is discussed as a non-invasive method of diagnosis and therapeutic approach to liquid paraffin pneumonia (in the cases herein described, between 100 and 500 mg of paraffin oil were extracted from 100 ml of bronchoalveolar washing fluid.

Oil-in-polyhydric alcohol type emulsified composition and oil-in-water type emulsified composition

Abstract: PURPOSE:To prepare an oil-in-water type emulsified composition dispersely stable with passage of time by dissolving hydrogenated lecithin, stevia and polyhydric alcohol by heating at a temperature equal to or higher than the melting point of lecithin and thereafter gradually adding oil thereto under agitation. CONSTITUTION:Polyhydric alcohol, hydrogenated lecithin and stevia are dissolved together by heating at a temperature equal to or higher than the melting point of hydrogenated lecithin, and the oil dissolved by preheating is gradually added thereto under agitation, thereby preparing an emulsified composition. By adding water to the resulting oil-in-polyhydric alcohol type composition, an oil-in-water type emulsified composition supremely excellent in stability can be obtained. It is preferable that the ratio of the dehydrogenated lecithin to the stevia is 1:9-9:1 by weight and that the concentration of the polyhydric alcohol solution including the hydrogenated lecithin and stevia is 1-75wt.%. Liquid paraffin, mink oil, cetyl isooctanoate, etc. are available as the additive oil.

Formation of W/O/W Emulsions through the Simple Agitation of Oil-Water Mixtures

Abstract: A W/O/W-type dispersion was developed together with O/W emulsions during the mechanically simple agitation of a series of mixtures of liquid paraffin and water containing hydrophobic (Span 80) and hydrophilic (SDS or Tween 80) emulsifiers in each liquid phase. The presence of W/O/W emulsion globules among simple oil droplets was confirmed by optical microscopy, globule size analysis and viscometry. The yield of this dispersion increased markedly, while the amount of Span 80 in the oil phase increased at a relatively low concentration of SDS or Tween 80 in the aqueous phase. This may possibly cause formation of the W/O/W emulsion during ordinary emulsification, should the system be comprised of more than two types of emulsifiers.

Separation of unsaturated chondroitin sulfate disaccharides in thin-layer chromatography on silica gel and their quantitative determination by densitometry.

Abstract: A simple and rapid method has been developed to determine the relative amounts of 4-and 6-sulfate in chondroitin sulfate or proteoglycan preparations. Unsaturated disaccharide products derived from the samples by chondroitinase ABC digestion in 0.01 M Tri-HCl buffer (pH 8.0) were applied to a silica gel-coated thin-layer chromatographic plate and separated in a solvent system of n-propanol-isopropanol-n-butanol-water (55 : 20 : 5 : 20, v/v) containing 0.04M NaCl and 0.01 M ammonia without a desalting step, which was necessary in paper chromatography or thin-layer chromatography on cellulose. The developing time was as short as 2-2.5 h at room temperature. After staining of the separated products with a carbazole reagent followed by immersing the plate in liquid paraffin, the ratio of monosulfated disaccharides, generally found as major components in chondroitin sulfate chains, was estimated by densitometry.

The occurrence of hydrogen peroxide in edible oils; chemical and microbiological consequences

Abstract: Evidence is presented for the occurrence of hydrogen peroxide at low concentration in edible oils and fats of both vegetable and animal origin. In soya bean, corn, groundnut, sunflower, rapeseed, olive, safflower, sesame, linseed and mackerel oils, and in the oil from lard, margarine and a solid vegetable fat, hydrogen peroxide was found at concentrations within the range 0.1-11.5 μg g−1 of oil. The highest ‘natural’ concentrations were found in soya bean oil. Detection of hydrogen peroxide in aqueous extracts of the various oils examined was based upon measurements by high performance liquid chromatography, luminescence, colorimetry and fluorimetry. The quantitative measurement of hydrogen peroxide was made using a fluorimetric assay. The hydrogen peroxide concentration found in a given oil was not directly related to the peroxide value of that oil. Hydrogen peroxide was found to re-accumulate in oil samples which had been washed free of their initial content. This process took place slowly over a period of days, and led to a steady state concentration of hydrogen peroxide in the oil. It is suggested that hydrogen peroxide arises as a by-product of the lipid autoxidation process. The rate of oxidation and the induction period at 40°C of soya bean oil ‘naturally’ containing 2.76 μg hydrogen peroxide per gram of oil were unaffected by the removal of hydrogen peroxide by water washing or by addition of further hydrogen peroxide to the oil. The hydrogen peroxide did not therefore appear to function as a significant source of hydroxyl radicals capable of initiating autoxidation reactions. In the presence of soya bean oil containing hydrogen peroxide (5 μg g−1) the lethal effect of heating at 90°C on spores of Clostridium sporogenes PA 3679 was much greater than that in a liquid paraffin control. Removal of hydrogen peroxide from the soya bean oil by washing with water considerably reduced the lethal effect, which was restored by the addition of hydrogen peroxide (7.5 μg g−1) to the washed oil.

Repeated isolation of nocardia like organisms from multibacillary cases of leprosy.

Abstract: Nocardia like organisms were isolated from all the 22 multibacillary cases of leprosy, on minimal media consisting of only mineral salts and supplemented with simple C-sources (e.g., liquid paraffin, tetradecane etc.) and N-sources (e.g. ammonium salts, urea, asparagine, gelatin etc.). Complex organic substances, e.g., xanthine, tyrosine, casein, peptone, meat extract, egg proteins, serum, blood, yeast extract as well as medium 199, did not support the growth of these organisms at all. Paraffin-urea minimal (PUM), paraffin gelatin minimal (PGM) and gelatin minimal medium, as well as the agar slants of these media, selectively allowed good growth of these organisms on which these could be serially propagated continuously, and isolated as pure cultures; these were acid-fast long slender rods which were seen to arise directly from fragmented or unfragmented long, slender hyphae, forming at places mycelial tufts many of which, on ageing, sporulated abundantly. Their acid-fastness was pyridine susceptible and these were DOPA-Oxidase positive; these grew best under reduced 02 tension, at pH 7.0-8.0 and temperature about 28 degrees C. Serologically, these appeared to be sufficiently related to, each other, 2 nocardiae (N. brasiliensis and N. caviae) and some mycobacteria.

Studies of the epidemiology and control of tomato stem rot caused by Didymella lycopersici

Abstract: Pycnidiospores of Didymella lycopersici were capable of inducing stem lesions when used at concentrations as low as two spores per 15-μl droplet, provided the inoculum was placed on wounded tissue and the relative humidity maintained at more than 90%. At c. 75% RH, lesions were not produced even at high spore concentrations and with pre-inoculation stem wounding. Pycnidiospores remained viable when stored for 17 weeks in sterile water and 14 weeks in nutrient solution. Detailed examination of tomato stems with a single lesion indicated that, in some cases, the pathogen may be widely distributed as it was isolated at distances of up to 1000 mm above the lesion and 750 mm below. Experiments on the transmission of D. lycopersici using sciarid flies demonstrated that, although this may be possible, it is probably infrequent in occurrence. None of the fungicides tested for the control of stem lesions were better than the standard benomyl in Actipron, but benomyl in medical-grade liquid paraffin was as good.
