N-[2-(2-Chloro-phen-yl)-2-hydroxy-ethyl]propan-2-aminium hemioxalate.

The asymmetric unit of the title compound, C(11)H(17)ClNO(+)·0.5C(2)O(4) (2-), consists of one N-[2-(2-chloro-phen-yl)-2-hydroxy-ethyl]propan-2-ammonium cation and one-half of a centrosymmetric oxalate anion. In the cation, the C/C/N plane of the ethyl-ammonium group is almost perpendicular to the benzene ring, with a dihedral angle of 88.

[Determination of three formulations of pilocarpine in rabbit ocular aqueous by RP-HPLC].

Objective: To develop an RP-HPLC method for assay of pilocarpine in rabbit ocular aqueous humor.

Methods: The RP-HPLC method was performed on a column of ODS-C(18) with the mobile phase consisting of 0.5% of triethylamine (TEA) of phosphate solutions (10 mmol/L, pH 2.

[Action of miosis of 1% pilocarpine liposome in rabbits].

Objective: To compare the action of miosis of 1% pilocarpine liposome with 1% pilocarpine solution in rabbits.

Methods: 18 white rabbits were randomly divided into 3 groups. Test group received 1% pilocarpine liposome, positive control group received 1% pilocarpine solution, negative control group received liposome.

[Peripheral iridoplasty with doubled-frequency Nd:YAG laser as treatment for angle-closure glaucoma].

OBJECTIVE: To examine the effects and safety of doubled-frequency Nd:YAG laser peripheral iridoplasty(LPI) for angle-closure glaucoma (ACG) with relieving the pupillary block. METHODS: Thirty-seven eyes of 29 patients of ACG with mean intraocular pressure (IOP) of (33.5+/-9.
