Neutralization of Chlamydia trachomatis was assayed by the decrease in inclusion-forming units in baby hamster kidney cells grown in culture. Five percent fresh guinea pig sera increased neutralization titers of rabbit antisera 100- to 1,000-fold but had no effect when normal rabbit sera were tested. Neutralization of a type A or B trachoma isolate was strain specific. Neutralization by human e...
PURPOSE To demonstrate a Scheimpflug-based imaging procedure for investigating the depth- and time-dependent strain response of the human cornea to inflation testing of whole eye globes. METHODS Six specimens, three of which with intact corneal epithelium, were mounted in a customized apparatus within a humidity and temperature-monitored wet chamber. Each specimen was subjected to two mechani...
When carefully controlled numbers of alloantigenic cells are injected into the anterior chamber o f the eye, they elicit an unconvent ional host immune response. This phenomenon, first described in a rat a l lo immune system (1, 2), has been successfully adapted to mice. B A L B / c mice, injected intracamerally with P815 tumor cells derived from the D B A / 2 mouse strain, can be rendered spec...

The ADAMTS family comprises 19 secreted metalloproteinases that cleave extracellular matrix components and have diverse functions in numerous disease and physiological contexts. A number of them remain 'orphan' proteases and among them is ADAMTS18, which has been implicated in developmental eye disorders, platelet function and various malignancies. To assess in vivo function of ADAMTS18, we gen...
We used the chemical mutagen, N-ethyl-N-nitrosourea, to induce random point mutations in the germline of the mouse strain C57BL/6 in order to generate models of retinal diseases. 1163 mutagenised first generation mice produced using this approach were examined for eye abnormalities. Approximately one-third (412) presented with some form of ocular abnormality. Most changes were unilateral and co...
Two congenic strains of RCS rats, RCS-p/+ and RCS-c, have been developed that differ from the parental strain at genetic loci affecting pigmentation. Inbred RCS rats are pink-eyed, while RCS-p/+ rats produce segregating litters of pink-eyed (p/p) and black-eyed (p/+) offspring, and RCS-c rats are albinos. All the strains are homozygous for the mutant form of the retinal dystrophy gene. The blac...
Eye trauma is a major problem in emergency rooms that could be prevented in the world. Over 0.5 milion individuals lose their vision due to eye trauma. Eye trauma is a major cause of monocular blindness. After occupational trauma, eye trauma at home, is a second cause (15-41%) of blunt trauma. Therefore in this study, we investigated home eye trauma in the emergency unit of Alavi Eye Center, ...
The majority of individuals appear to have insight into their own sleepiness, but there is some evidence that this does not hold true for all, for example treated patients with obstructive sleep apnoea. Identification of sleep-related symptoms may help drivers determine their sleepiness, eye symptoms in particular show promise. Sixteen participants completed four motorway drives on two separate...
