Abstract: A composition for the transdermal delivery of a biologically active peptide having a molecular weight of about 5,000 or less comprising at lest one biologically active peptide, at least one higher alcohol, ester and/or higher amide in combination with at least one pyrrolidone compound of the formula: ##STR1## where R.sub.5 is hydrogen or a lower alkyl group having 1 to 4 carbon atoms, R.sub.6 is hydrogen or a lower alkyl group having 1 to 3 carbon atoms and n is 3, 4 or 5. A method for percutaneously administering such a composition is also disclosed.

Abstract: A method of percutaneously administering a physiologically active agent which comprises applying to the skin of a mammal a physiologically active agent in a carrier system which comprises at least one adjuvant, at least one solvent and at least one diol and/or triol moderator. The adjuvant can be selected from aliphatic hydrocarbons, halogen substituted aliphatic hydrocarbons, alcohol esters of aliphatic carboxylic acids, mono- or di-ethers, ketones, higher monoalcohols or mixtures thereof. The solvent can be selected from thioglycerols, lactic acid and esters thereof, cyclic ureas, compounds represented by the general formula R.sub.1 R.sub.2 NCONR.sub.3 R.sub.4, pyrrolidone-type compounds, amides, lactones or mixtures thereof.

Abstract: A method of percutaneously administering metoclopramide which comprises applying to the skin of a mammal metoclopramide in a carrier system which comprises at least one adjuvant and at least one solvent. The adjuvant is a monovalent alcohol ester of an aliphatic monocarboxylic acid or an aliphatic monoalcohol. The solvent is a pyrrolidone-type compound. Mixtures can also be used.

Abstract: Process for repelling ticks and other biting insects comprising topically administering to humans or to domesticated animals a composition comprising at least one active compound selected from the group made up of alkylated pyrrolidones and alkylated pyrrolidenones.

Abstract: Increased yields of the cellulolytic enzymes from Thielavia terrestris are effected by novel separatory methods for the produced enzymes as well as the enhancement of the production of one of the enzymes, namely .beta.-glucosidase, by the addition of glycerol to the media. Further, since the .beta.-glucosidase is responsible for glucose production from cellulose, a method is provided wherein the separated .beta.-glucosidase can be employed as, for example, on a fixed support in a position to receive concentrated streams of partially converted cellulosic materials, thereby leading to enhanced glucose production.

Abstract: A thermostable cellulase preparation exhibiting C.sub.1 and C.sub.x cellulytic activities at a temperature from about 60.degree. to about 70.degree. C at a moderately acid pH from about 5.0 to about 5.6 is obtained by culturing the thermophilic fungus Thielavia terrestris (NRRL 8126) in a suitable cellulose-containing medium and recovering the cellulases thus produced.
