Extensive visual loss with topical facial steroids.

Steroid creams applied topically to the skin are routinely used in the treatment of many dermatoses. Their use on the face in severe atopic eczema is relatively common. We report a series of three patients who whilst using topical facial steroids developed advanced glaucoma.

Characterization of 2-[125I]iodomelatonin binding sites in the brain of a marsupial, Bennett's wallaby (Macropus rufogriseus rufogriseus).

1. Specific high affinity binding of 2-[125I]iodomelatonin was detected in the brain of the pouch young of a marsupial, Bennett's wallaby. 2.

The ontogeny of 2-[125I]iodomelatonin binding sites in chicken brain.

The characteristics of the binding sites for 2-[125I]iodomelatonin were studied in chicken brain membranes during development. Specific binding, defined using cold melatonin (1 microM), was detected as early as 8-day-old embryos. Scatchard analysis of saturation experiments showed that 2-[125I]iodomelatonin binds to a single class of site at all ages tested (8-day-old embryos to 3-month-old chicks).

Analysis of priority substituted phenols by micellar electrokinetic chromatography.

The use of micellar electrokinetic capillary chromatography (MECC) for the separation of eleven substituted phenols listed by the United States Environmental Protection Agency as priority pollutants was demonstrated. The effects of the pH and ionic strength of the buffer, and the length of the separation column on resolution were investigated. The retention characteristics of the eleven phenols in MECC are discussed.

Guanine nucleotides regulate 2-[125I]iodomelatonin binding sites in chick retinal pigment epithelium but not in neuronal retina.

The characteristics of the binding sites labeled by the radioligand 2-[125I]iodomelatonin were compared in chicken neuronal retina and retinal pigment epithelium (RPE). Specific binding of 2-[125I]iodomelatonin in both sites was stable, saturable, reversible, and of high affinity. Scatchard analysis revealed an affinity constant (KD) of 446 +/- 55 pM and a total number of binding sites (Bmax) of 25.

Small-scale field trials of Bacillus sphaericus (strain 2362) formulations against Mansonia mosquitoes in Malaysia.

Five formulations of Bacillus sphaericus (strain 2362) including aqueous suspension BSP 1, BSP 2, technical powder ABG 6184, corncob granules ABG 6185 (potencies 2 x 10(10), 2 x 10(7), 9.5 x 10(10), 5 x 10(10), 5 x 10(10) spore/g, respectively) and wettable powder ABG 6232 (1,000 BS ITU/mg) were tested against laboratory-cultured late third/early fourth instar larvae of Mansonia uniformis in floating screened cages in small plots at swampy ditches on Penang Island, Malaysia. Mean dosage/response values at 90% mortality levels were 6.

Pharmacological identity of 2-[125I]iodomelatonin binding sites in chicken brain and sheep pars tuberalis.

2-[125I]Iodomelatonin was used to compare the binding and pharmacological characteristics of the melatonin receptor sites found in chicken brain and sheep pars tuberalis. Scatchard analysis and kinetic experiments showed that 2-[125I]iodomelatonin binds to a single class of site in both tissues with high affinity (Kd 20-34 pM). Competition experiments, using 21 analogues of melatonin, gave inhibition constants (Ki) for the two sites which were significantly correlated (r = 0.

Field efficacy of mosquito coil formulations containing d-allethrin and d-transallethrin against indoor mosquitos especially Culex quinquefasciatus Say.

Comparative field efficacy studies of four mosquito coil formulations containing active ingredient of d-allethrin (0.19 or 0.28 w/w) and d-transallethrin (0.

Retention of eleven priority phenols using micellar electrokinetic chromatography.

The use of micellar electrokinetic chromatography (MECC) for the separation of eleven substituted phenols listed by the United States Environmental Protection Agency as priority pollutants was investigated. Solutions of potassium and sodium dodecyl sulphate in phosphate-borate buffer of pH 6.6, 7.

L-NG-nitro arginine (L-NOARG), a novel, L-arginine-reversible inhibitor of endothelium-dependent vasodilatation in vitro.

1. The effect of L-NG-nitro arginine (L-NOARG) was compared with that of L-NG-monomethyl arginine (L-NMMA) on vasodilatation of the isolated aorta of the rabbit and perfused mesentery of the rat in response to acetylcholine (ACh) and sodium nitroprusside (NP). 2.
