A saw handle adapted to have a blade engaged therewith and further including a gripping area to allow a user to firmly hold the saw handle, the saw further including a flexible guard member which is movably secured to the saw handle adjacent to the blade such that the flexible guard is movable to extend along the toothed edge of the saw blade to be attachable thereto for protection of the teeth of the saw blade as well as for protection of the surrounding environment from the teeth of the saw blade, the flexible guard being secured to the handle by way of a resilient retaining member such as a spirally wound recoil spring which will wind the flexible guard means automatically in a circular fashion within the handle whenever the guard itself is not being pulled outwardly for placement adjacent the toothed edge of the blade, the handle defining a recess into which the flexible guard and the resilient retaining member are located, the flexible guard possibly further including a hook eye adapted to slide into a slot defined by the blade at the forward edge thereof to hold the guard in fixed engagement with respect to the teeth of the blade, in this manner the automatically recoiling flexible blade guard will be retained in a somewhat remote location whenever the saw is in normal use and will be able to be withdrawn from the recess and placed in engagement with the teeth of the blade easily and quickly, the blade also preferably including a knife area for starting cuts as defined by the blade member.

A synthetic decapeptide, L-pglutamyl-L-histidyl-L-tryptophanyl-L-seryl-L-tyrosyl-glycyl-L-leucyl-L- arginyl-L-prolyl-glycinamide which has the hormonal activities of the luteinizing hormone releasing hormone (LRH) of the hypothalamus gland of mammals is produced by utilizing as the key starting materials, the amino acids, glutamic acid or pyroglutamic acid, histidine, tryptophan, serine, tyrosine, glycine, leucine, arginine, and proline. Synthesis of the decapeptide is accomplished by coupling, in appropriate combinations of appropriate protected forms of the amino acids, and finally deprotecting to yield the amide, L-pglutamyl-L-histidyl-L-tryptophanyl-L-seryl-L-tyrosyl-glycyl-L-leucyl-L- arginyl-L-prolyl-glycinamide.

A method for producing the Folliculotropin Releasing Hormone (FRH) biosynthetically is provided by utilizing, as key starting materials, fresh hypothalamic tissue, a buffered incubation medium, an ATP synthesizing system, radioactively labeled amino acids and a mixture of 21 naturally occuring amino acids. Biosynthesis of the FRH is accomplished by incubation of the hypothalamic tissue for a short period of time in the presence of all the reagents necessary to promote the biosynthetic system to produce the Folliculotropin Releasing Hormone (FRH) of the hypothalamus gland of mammals. Examples of methods to isolate the FRH free of the luteotropin releasing hormone (LRH) are provided.
