Balsams are sticky, clear exudates from wood and resin pockets in the bark of certain conifers. The most useful one, Canada balsam, has been obtained from Abies balsamea (2). Canada balsam is mainly used in microscopy. It is produced on a small scale from the gum exuded from the blister resin pockets in the winter. A similar product, Oregon balsam, was obtained from Pseudotsuga menziesii (2). Production and value data for Canada balsams are available only up 1965 (6) because of infrequently collected statistics. The amount produced in 1965 was over 51000 pounds. Sandermann (25) discussed the physical and chemical properties of 33 different balsams, their major components, and qualitative tests to distin-...

Oregon balsam is an oleoresin that occurs in the tree trunk and is usually collected from felled trees. It is a light amber or yellow, viscous liquid with a piney odor. It is not a true balsam (see glossary). The tree varies greatly in size, depending on localities often up to 60 m high with a trunk of approximately... 

Similar to those of Canada balsam used as an adulterant of the latter oleoresin however, Oregon balsam is not suited for use in microscopy because it is less viscous and slower drying than Canada balsam it does not dry to a glassy and brittle film as Canada balsam. 

ALT AND AST. Alanine aminotransferase and aspartate aminotransferase are enzymes located in liver cells that leak out into the general circulation when liver cells are injured. Previously known as the SGPT (serum glutamic-pymvic transaminase) and the SCOT (serum glutaic-oxaloacetic transaminase), respectively ATPASE. Adenosine triphosphatase BALSAMS. Mixtures of resins that contain relatively large amounts of cinnamic or benzoic acid or their esters. Typical balsams are balsam Peru, balsam Tolu, styrax, and benzoin. Canada balsam, Oregon balsam, and copaiba balsam are not true balsams since they do not contain benzoic or cinnamic acid or their esters. Balsams are insoluble in water but soluble in alcohol...
