BACKGROUND A randomized, controlled trial was conducted in an outpatient setting to examine the effect of beta-blocker dosing frequency on patient compliance, clinical outcome, and health-related quality of life in patients with stable angina pectoris. METHODS One hundred and twelve beta-blockers-naive outpatients with stable angina pectoris were randomized to receive betaxolol, 20 mg once da...

In the title compound, 2C(8)H(20)N(+)·2C(4)H(5)O(6) (-)·C(4)H(6)O(6)·H(2)O, the presence of the two tetra-ethyl-ammonium cations is balanced by two hydrogen l-tartrate anions. Also present in the asymmetric unit are a mol-ecule of l-tartaric acid and a water mol-ecule. The various components are linked by O-H⋯O hydrogen bonds. In the crystal, two-dimensional networks are formed via O-H⋯O hydrog...

A monoclinic polymorph of the title compound, [Na(C(4)H(5)O(6))(H(2)O)](n), is reported and complements an ortho-rhom-bic form [Kubozono, Hirano, Nagasawa, Maeda & Kashino (1993 ▶). Bull. Chem. Soc. Jpn, 66, 2166-2173]. The asymmetric unit contains a hydrogen tartrate anion, an Na(+) cation and a water mol-ecule. The Na(+) ion is surrounded by seven O atoms derived from one independent and thre...

In membranes, the chirality of the amphiphile constituents is sometimes expressed at a supramolecular scale of nanometers or micrometers. We have recently reported that membranes of nonchiral dicationic n-2-n amphiphiles can also be chirally twisted upon interacting with chiral tartrate counterions. Here, we demonstrate that the mechanism of the chiral induction by counterions involves specific...

There is some evidence that atropine interferes with pharmacologically induced ejaculation in the mouse (Loewe, 1938; Loewe & Puttuck, 1953) and alters the physical and chemical composition of semen of other animals (Dziuk & Norton, 1962; Dziuk & Mann, 1963). Very little, however, is known about the effect of adrenaline on the composition of semen, and of adrenaline and atropine on the morpholo...

To the Editor, The Indian Medical Gazette. Sir,?Dr. Brahmachari advises the use of sodium chloride in making up antimony solutions for injection, ' and Drs. Napier and Muir state that the use of sodium chloride does not matter much and their injections can be given without sodium chloride. I have recently noticed in my kala-azar centres that while using scale preparation of sodium antimony tart...

THE PRINCIPAL CONCLUSIONS THAT SEEM TO ME JUSTIFIED ARE AS FOLLOWS: 1. The fluorescent pigment formed by some varieties of B. pyocyaneus is produced under conditions identical with those governing the production of the pigment by other "fluorescent bacteria." 2. The production of pyocyanin is not dependent upon the presence of either phosphate or sulfate in the culture medium. It is formed in n...

The asymmetric unit of the title compound, 2C(14)H(13)N(2) (+)·2C(4)H(5)O(6) (-)·9H(2)O, contains two cations and two anions in addition to nine mol-ecules of water. Each of the hydrogen tartrate anions is hydrogen bonded to itself by translation along [100] in a head-to-tail fashion via a short hydrogen bond with donor-acceptor distances of 2.473 (4) and 2.496 (4) Å. A large number of inter-mo...

The method for sulfamethazine using post column derivatization (Associate Referee Robert Smallidge) was adopted First Action in 1999. There are a number of methods which could be readied for collaborative study with relatively little work, i.e., carbadox, ethopabate, lasalocid, or morantel tartrate. In addition to the remarks made for the following Associate Referee topics, readers can refer to...

Major J. A. CRUICKSHANK, m.c., m.d., i.m.s., (Assistant Director.) (From the King Institute of Preventive Medicine, Guindy, Madras.) Sami Sabongy Be;y in his article on smallpox in volume III of Byam and Archibald's " Practice of Medicine in the Tropics " has published a series of photographs illustrating the treatment of the disease in the human subject by means of intravenous injections of an...
