A comparative study of the intraocular pressure-lowering effects of timolol and phospholine iodide in cases of aphakic glaucoma was carried out. The authors compared the I.O.P.-lowering effect of these two drugs in 30 eyes (30 patients) with aphakic glaucoma over an eight-month observation period. The following was established after a statistical analysis of the material: 1. The I.O.P.-lowering effect of timolol in aphakic glaucoma cases is almost identical with the effect of the drug in cases of chronic open-angle glaucoma. 2. The administration of phospholine iodide in such cases leads to a stable I.O.P. regulation and it seems that this therapy should be preferred to treatment with timolol. 3. Timolol therapy in cases of aphakic glaucoma should be considered an enrichment of the known treatment methods. 4. The administration of timolol requires constant follow-up and if this is not possible therapy with pilocarpine or phospholine iodide should be preferred.

Glaucoma Following Cataract Surgery (GFCS) remains a menace, so parents must be counseled prior to cataract removal in children. Age less than 7 months at the time of surgery increases this risk, and IOL placement has no effect. To lower IOP in GFCS, start with drops and before you escalate to surgery, consider phospholine iodide.

Enzyme-catalyzed hydrolysis of echothiophate, a P-S bonded organophosphorus (OP) model, was spectrofluorimetrically monitored, using Calbiochem Probe IV as the thiol reagent. OP hydrolases were: the G117H mutant of human butyrylcholinesterase capable of hydrolyzing OPs, and a multiple mutant of phosphotriesterase, GG1, designed to hydrolyze a large spectrum of OPs at high rate, including V agents. Molecular modeling of interaction between Probe IV and OP hydrolases (G117H butyrylcholinesterase, GG1, wild types of and phosphotriesterases, and human paraoxonase-1) was performed.

The single residue mutation of butyrylcholinesterase (BChE) hydrolyzes a number of organophosphosphorus (OP) anticholinesterases. Whereas other BChE active site/proximal mutations have been investigated, none are sufficiently active to be prophylactically useful. In a fundamentally different computer simulations driven strategy, we identified a surface peptide loop (residues 278-285) exhibiting dynamic motions during catalysis and modified it via residue insertions.
