The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Z .Z .E to Z ,Z,Z-isom erization of dihydrobilins. Its amplitude depends on the reaction conditions, with a maximum corresponding to 15% conversion of one of the three PC chromophores. This chromophore is suggested to be ß-153, for which recent X-...

PURPOSE To investigate the efficacy of 0.1%, 0.15%, and 0.3% sodium hyaluronate (SH) artificial tears compared with 0.05% cyclosporine (CS) ophthalmic solution for the treatment of dry eye. METHODS One hundred seventy-six patients were recruited and randomized to receive of 0.1%, 0.15%, and 0.3% SH and 0.05% CS. There was a primary end point which is the changes in the fluorescein corneal sta...

PURPOSE To determine the correlative relationship between the prevalence of Demodex in eyelashes and the severity of ocular discomfort, by investigating the demographic epidemiology associated with Demodex. METHODS One hundred seventy patients underwent epilation of four eyelashes of each eye, and the number of Demodex was counted. The patients answered questionnaires about ocular surface dis...

PURPOSE To compare corneal reepithelialization, pain scores, ocular discomfort, and tear production after photorefractive keratectomy (PRK) and butterfly laser epithelial keratomileusis (LASEK). METHODS This prospective, randomized, double-masked study comprised 102 eyes of 51 patients who underwent laser refractive surgery. Each patient was randomized to have one eye operated on with PRK and...

Aim of the study was to evaluate the diagnostic performance of the Rose Bengal score test for Sjøgren's syndrome (SS), and to explore differences between other tests and examinations. All participants were examined, including (but not limited to) unstimulated (UWS) and stimulated (SWS) whole saliva, labial gland biopsy (LGB or focus score), ophthalmologic questionnaire (ocular surface disease i...

Tension pneumocephalus is the presence of air or gas in the cranium that is under pressure. It occurs due to disruption of the skull, including trauma to the head or face, after neurosurgical procedures and occasionally, spontaneously (Schirmer et al., 2010). Patients typically present with headache but can also have neurological deficits such as decreased mental status, numbness, and weakness ...

The purpose of this study was to determine the prevalence of ocular surface disease symptoms and the state of the tear film among patients with glaucoma who are receiving topical intraocular pressure lowering monotherapy. 62 responders were divided in 2 groups: 32 glaucoma patients and 30 healthy individuals. Tear film break-up time (TBUT), Schirmer 1 testing and ocular surface disease question...

a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

THE Schirmer I tear test developed and standardized by Halberg and Berens, New York City (Contactisol Inc. Lindenhurst, N.Y.) is a useful screening procedure for keratoconjunctivitis sicca in large numbers of patients suffering from various connective tissue disorders. When all the patients attending a centre for rheumatic diseases were subjected to this test it was noted that a surprisingly hi...
