A nonconventional method for the evaluation of emulsion stability was developed. The method was valid for viscous emulsions. The technique is based on elec. cond. measurements during nondestructive short-cooling-heating cycles carried out on cosmetic viscous emulsions. Cond. curves were obtained on a recorder, where the second heating cycles were lower and almost parallel to the first heating curves. The bigger the cond. differences between the two heating curves, the lower was the emulsion stability. A relative Stability Index $Δ$/h, indicating relative change in cond. between 2 cycles was elaborated. This index was useful for detg. optimal required hydrophile-lipophile balance values for required emulsions, optimal amt. of oily phase and emulsifier concn. [on SciFinder(R)]
Fatty acid esters of glycerol or tetraglycerol are prepd. by the transesterification of Me esters of fatty acids (esp. Me stearate [112-61-8]) with glycerol or tetraglycerol at 95-150° in the presence of an alk. catalyst and an anionic or nonionic emulsifier. These esters are not highly substituted. Emulsion formation and the catalyst are required for high transesterification yields. The effects of temp., type and concn. of emulsifier, and reactant ratio on the transesterification were examd.

The oxidn. of oleic acid and the cleavage of the carbon-carbon bond was achieved using potassium permanganate added to oil in water emulsion. The best emulsifier for the oxidn. and cleavage of the double bond was polyoxyethylene lauryl ether (HLB 16.9) which formed the best emulsion with the smaller droplets. The oxidn. is controlled by parameters affecting emulsion stability. Increasing the concns. of emulsifier or oxidizing agent improves the oleic acid conversion and azelaic acid formation. Poor stirring, low HLB's, high oil phase content and poor emulsion prepn. decrease the yields. [on SciFinder(R)]
Isolated human peripheral blood neutrophils were exposed to sonic extracts of Actinobacillus actinomycetemcomitans. Such bacterial preparations contain a potent leukotoxin which rapidly kills the leukocytes as reflected by cellular uptake of trypan blue, extracellular release of lactate dehydrogenase, or discharge of 51Cr from pre-labeled cells. Exogenous phospholipids with a glycerol skeleton esterified by fatty acids or positively charged liposomes inhibited cytotoxic phenomena. The data suggest that cell damage may involve the interaction of leukotoxin with phospholipids in the neutrophil cell membrane and that exogenous lipids either compete for or sterically block binding of the leukotoxin to these moieties in the membrane.

Product compn. of polyglycerol esters, prepd. from a direct alk. polymn. of glycerol followed by esterification with stearic or oleic acids, was studied. The internal product compn., as analyzed by high performance liq. chromatog. (HPLC), shows clearly that in contradiction to what has been published recently, the fatty acid radicals are not distributed at random among all available hydroxyl groups, and thus, any theor. calcn. on the product compn. could not be correct. The product compn. of the crude material indicates clearly that the internal positions (secondary hydroxyls) of the glycerol polymer are esterified with greater difficulty than the primary hydroxyl groups.

Here, for the first time, is a general survey of ancient ivory work, of value to both the general reader and the specialist. The finds discussed in this volume come from a wide extent of countries from Spain to India and range in date from the late Chalcolithic period up to the establishment of the Byzantine empire. Topics explored include the elephant and ivory working, ivory workers, workshops, guilds, trade, and prices. The text features photographs (including many rare ones) of nearly 300 ivory objects, as well as line drawings and maps.

The excavation of Prof. E.L. Sukenik at Tell Jerishe (in present-day Ramat Gan) was one of the pioneering archaeological undertakings during the days of the British Mandate; a final season took place in 1951. Since the excavator died before he could work on the stratigraphy and finds, the results of his labors did not receive the recognition due to them. During the 1951 season, Sukenik had concentrated on the fortifications, a combination of wall and glacis that was little known at the time. Three decades later, S. Geva accomplished the formidable task of publishing this important Middle Bronze II fortification complex. In order to clarify certain points, she conducted a short season at Tell Jerishe in 1976. Her stratigraphic and structural analysis is copiously illustrated with plans and sections from both the 1951 and 1976 excavations. A large collection of sherds from four strata is presented in order to establish the date of construction of the fortification complex.

It has been found that calcium oxalate stone formers have low UGOT activity compared to healthy individuals (controls). Urine from stone formers with no GOT activity and no effect on calcium oxalate precipitation was incubated with GOT for various periods. Subsequently calcium oxalate precipitation was decreased and found to be considerably retarded i.e., the pathological urine after the incubation acted in a way similar to that of normal urine. The yield of Glutamic-Oxalacetic Transaminase (GOT) activity is glutamic acid. It was shown that glutamic acid has a significant retardation effect on the precipitation of calcium oxalate stone formation. Therefore it may be suggested that GOT activity involved in glutamic acid creation in situ, has a role in kidney stone formation.[on SciFinder (R)]
It is postulated that lysosomal enzymes of leukocytes are capable of breaking down bacterial constituents and to cause bacteriolyasis. Studies from our laboratory have shown that radiolabled staphylococci (log-phase) arm readily lysed by leukocyte extracts at pH 5.0. On the other hand, old cells or heat-killed young cells are resistant degradation. The leukocytes extracts can be affectively replaced by cationic proteins as well as by membrane-damaging agents (phospholipase A2, polymaxins). Studies on the mechanisms of bacteriolysis have suggested that the cationic proteins act by activating the bacterial autolytic enzymes leading to bacteriolysis. This proces can be inhibited by a series of anionic polalalectrolytes likely to preent in inflammation, presumably by inactivating autolytic enzymes. The cooperation between PHNs and macrophages in bacteriolysis and control of bacterial growth by polalalectrolytes will be discussed in relation to the phatogenesis of the infection and inflammation.
