Determination of fluorometholone purity by very high-performance liquid chromatography
Selective reduction of aromatic / aliphatic nitro groups by sodium sulfide.
[Comparative study of the antiglaucomatous activity of Glauplex 2 and pilocarpine nitrate on alpha-chymotrypsin-induced experimental glaucoma].
The antiglaucomatous effects of Glauplex 2 and pilocarpine nitrate on alpha-chymotrypsine-induced experimental glaucoma were studied in 8 rabbits and the antihypertensive effect of a single instillation of GlAUplex 2 was shown to be approximately equivalent to that of two instillations of 2.6 p.
The bioavailability and pharmacokinetics of three zinc salts: Zinc pantothenate, zinc sulfate and zinc orotate
It was shown that the dissolution behaviour of these zinc salts in water does not correlate with the parameters found in vivo, and they appear to be bioequivalent.
Simultaneous determination of atropine sulphate and tropic acid by reversed phase high-pressure liquid chromatography.

An improved spectrophotometric procedure for oxidized and reduced glutathione determination in erythrocytes is described, which offers the advantage of not having to use alkylation products to prevent oxidation of GSH during protein precipitation.

The accuracy and reproducibility of this rapid method make it useful for chlorhexidine determination in the manufacturing control of pharmaceutical mixtures.
Characterization of alpha 2-adrenergic receptors, negatively coupled to adenylate cyclase, in rabbit ciliary processes.
Alpha 2-receptor selectivity in rabbit ciliary processes and their negative coupling to an adenylate cyclase via a NaCl-dependent GTP binding protein, Ni, is thus well established.
New chiral and isomeric cyclopropyl ketoxime propanolamine derivatives with potent beta-adrenergic blocking properties.
The synthesis of R-(+) and S-(-) isomers of O-[3-tert-butylamino)-2-hydroxypropyl] cyclopropyl methyl ketone oxime (falintolol) is described and structure-activity relationships are described.
Effects of adrenergic agents on alpha-chymotrypsin-induced ocular hypertension in albino and pigmented rabbits: a comparative study.
Comparing the intraocular pressure response following the ocular application of single or repeated adrenergic agents in conscious albino and pigmented rabbits suggests that the pigmented layers of the iris-ciliary body may act as sites for topically applied antiglaucoma drugs.
