Substance P and antistrychnine activity
Naunyn-Schmiedebergs Archiv f�r Pharmakologie und Experimentelle Pathologie, 1968The administration to mice of crude substance P prepared from bovine brain inhibited strychnine convulsions. After alumina column chromatography, this antistrychnine activity was observed mainly in the fraction which was not adsorbed, while those fractions containing substance P or its satellite polypeptides (Zetler, 1963) were found ineffective.

Antimicrobially active substances
Folia Microbiologica, 1970The antimycotic activity of 41 quaternary ammonium compounds was studied. The spectrum of their effect was evaluated in eight microbial strains. Homologues, isomers or close analogues of Septonex, i.e. α-carbetoxypentadecyl-trimethylammonium bromide (XII) were found to be the most active.

Activity, Process, Continuant, Substance, Organism
Philosophy, 2016AbstractThis paper is a response to the suggestion that processes provide a better framework for interpreting science, biological science especially, than do substances. The philosopher of substance is ill-prepared, it has been suggested, for the question ‘how a combination of processes can maintain the appearance of stability and persistence in an ...

The activating substance in peripheral nerve
Experimental Neurology, 1964Abstract Incubation of rat sciatic nerve in a phosphate-buffered, glucose-free medium is associated with the rapid formation and diffusion of an “activating” substance from the nerve into the surrounding medium. When this substance is lost from the nerve, the subsequent respiratory rate of the depleted, i.e., “deactivated,” nerve is not increased in ...

Immunoregulatory activity of substance P fragments
Molecular Immunology, 1990The C-terminal SP7-11 pentapeptide (Phe-Phe-Gly-Leu-Met-NH2) was found to suppress in vitro the immune response in a dose of 1-5 micrograms/ml. It produced also a distinct immunosuppression in vivo, by both per os and intraperitoneal, applications. In contrast, the N-terminal SP1-4 fragment (Arg-Pro-Lys-Pro) suppressed the response at a dose of 0.1 ...

Biologically Active Substances in Royal Jelly
1966Publisher Summary This chapter discusses biologically active substances in royal jelly. The composition of royal jelly must be compared with that of worker jelly to determine whether there are qualitative and quantitative differences in these foods. Such analyses would serve as a basis for the development of partial or complete synthetic larval foods.

Alternative sources of biologically active substances
Folia Microbiologica, 2003The majority of antibiotics and substances with diverse biological activity used in medicine are produced by actinomycetes, nonfilamentous bacteria and fungi. Other microorganisms, such as myxobacteria, pseudomonads, nocardias, basidiomycetes, marine microorganisms, enterobacteria, halobacteria, hyperthermophiles etc.
