Abstract: A high pressure liquid chromatography jacket includes a rectangular, fluid-tight enclosure which has a removable cover on which a pair of tubing seal fittings are mounted. The fittings form a fluid-tight seal around the inlet and discharge tubes of a chromatographic column which is mounted in the enclosure. The enclosure is connected to a source of temperature controlled fluid which circulates through the enclosure and controls the temperature of the chromatographic column.In an alternative embodiment of the invention, a valve is provided which allows sample materials being loaded to enter a sample storage loop, which is exposed to the temperature controlled fluid. The sample, whose temperature has been controlled by the temperature controlled fluid, is then injected into a chromatographic column under high pressure.

Abstract: 6-Hydroxy-2-(2-hydroxy-4-methoxyphenyl)benzofuran derivatives and related pharmaceutical compositions and methods of treatment are disclosed. The compounds are useful as inhibitors of mammalian leukotriene biosynthesis. As such, they are useful therapuetic agents for treating allergic conditions, asthma, cardiovascular disorders and inflammation.

Abstract: An all-TEFLON filter-degasser for removing solids and gases from a solvent. The filter-degasser has a filtering portion, a vacuum application portion downstream of the filtering portion, and a solvent bottle connecting portion. The vacuum application portion includes an externally tapered male member, and the solvent bottle connecting portion includes an internally identically tapered female member. The male member can be inserted into and withdrawn from the female member without requiring any relative rotation therebetween, so that the filter-degasser can be connected hermetically airtight to the solvent bottle likewise without any rotation being required therebetween. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: Substances isolated after cultivation of a microorganism belonging to the genus Aspergillus in a culture medium comprise compounds which have structures: ##STR1## Together with salts and esters of the carboxylic acid, these compounds form a class of highly active hypocholesteremic and hypolipemic medicaments.

Abstract: 4-Amino- and 2,4-diaminopyrimidines with a quaternized ring nitrogen and an oxygen bearing substituent such as hydroxyalkyl, alkoxyalkyl, or alkanoyl on one of the exo- or endocyclic nitrogens and a C.sub.6-18 alkyl on another, are highly active antimicrobial agents with a relatively low acute mammalian toxicity.
