The compound 5-[(1-hydroxy-1-methyl)ethyl]-1-methyl-2-nitroimidazole is valuable in combatting Trichomonas vaginalis infections in mammals.

The pentapeptide: H-Tyr-Gly-Gly-Phe-D-Lys-OH, or a non-toxic salt thereof, exerts an analgesic effect in rats by injection into the lateral brain ventricle.

This invention relates to the selective herbicidal activity of fluoroaminopyridazines. In particular, these compounds exhibit preemergence and postemergence herbicidal activity on many of the major weeds including perennial weeds such as nutsedge and quackgrass. These compounds are particularly effective in selectively controlling weeds in agronomic crops.

Novel dopaminerginic compositions comprised of an dopaminergically effective amount of at least one member of the group consisting of N-(3,4-methylenedioxy-benzyl)-N'-(2-pyridyl)-piperazine and its non-toxic, pharmaceutically acceptable acid addition salts and an inert pharmaceutical carrier and to a novel method of treating the symptoms of Parkinson disease.

This invention relates to novel substituted indolopyrones which have utility in preventing allergic and asthmatic reactions in mammals.

The pentapeptide: H-Tyr-Gly-Gly-Phe-Ser-OH, or a non-toxic salt thereof, exerts an analgesic effect in rats by injection into the lateral brain ventricle.

The novel thymic factor polypeptide hormone, elaborated by the thymus and und in the blood serum, is isolated. The hormone is useful for the treatment of autoimmune diseases and for selectively stimulating T-cell activity in aging subjects.

The polypeptides R-Tyr-Gly-Gly-Phe-Met-Thr-Ser-OH in which R is hydrogen or arginyl, or a non-toxic salt thereof, exert an analgesic effect in rats when injected into the lateral brain ventricle.

The polypeptide H-Tyr-Gly-Gly-Phe-Leu-Thr-Ser-Glu-Lys-Ser-Gln-Thr-Pro-Leu-Val-Thr-OH, or a non-toxic salt thereof, exerts an analgesic effect in rats when injected into the lateral brain ventricle.

A portable line activity monitor is disclosed which utilizes a dedicated computer to tabulate a wide range of line traffic parameters. Preferably this monitor is used with a bridging adapter which accepts standard 50 pin telephone connectors as inputs in either the six line or the ten line pin format without adjustment or alteration, and the monitor computer is programmed to ignore all activity on those lines which never enter the idle or onhook state. In the preferred embodiment the computer is...
