Effect of vasoactive intestinal peptide on the wound healing of alkali-burned corneas

International Journal of Ophthalmology(English edition) 2016年第2期9卷 204-210页

AIM： To study the effect of vasoactive intestinal peptide （VIP） on wound healing in experimental alkali burns of the cornea. METHODS： Twenty-seven albino rabbits, weighing 3.2 -0.75 kg were used. Alkali burns were induced on corneas by applying 10 mm Whatman paper No：50 soaked in 1 mol/L NaOH. They have further classified into 5 groups as follows： 1） control group given no treatment （n=5）; 2） VIP given subconjunctivally （n=6）; 3） VIP injected into anterior chamber （n=6）; 4） NaCI 0.9% given subconjunctivally （n=5）; 5） NaCI 0.9% given into the anterior chamber （n=5）. All treatment protocols except control group were followed by topical eye drops composed of VIP at two hourly intervals for one week from 8 *** to 6 p.m, RESULTS： VIP treated groups of rabbits with alkali burns were found to have better wound healing findings histo-pathologically when compared to those of control group who have received no treatment on day 30. No differences were observed between groups in respect to degree of polymorphonuclear leukocytes （PMNL） infiltration and degree of loss of amorphous substrate on day 15. However, PMNL infiltration and degree of loss of amorphous substrate were lower in Groups 2 and 3 when compared to that of control group on day 30 （P〈0.05）. CONCLUSION： We have shown that VIP has positive effects on alkali induced corneal burns. VIP may inhibit PMNL migration to cornea through an immunomodulatory effect. Inhibition of PMNL migration might reduce the release of collagenaees and this might prevent the extracellular amorphous substance loss.

AIM： To investigate the role of vasoactive intestinal peptide（VIP） in form-deprivation myopia（FDM）.METHODS： FDM was created in three groups of eight chicks by placing a translucent diffuser on their right *** injections of saline and VIP were applied once a day into the occluded eyes of groups 2 and 3,*** and axial length（AL） measurements were performed on the first and 8^th days of diffuser *** retina mR NA levels of the VIP receptors and the ZENK protein in right eyes of the three groups and left eyes of the first group on day 8 were determined using real time polymerase chain reaction（PCR）.RESULTS： The median final refraction（D） in right eyes were-13.75（-16.00,-12.00）,-11.50（-12.50,-7.50）,and-1.50（-4.75,-0.75） in groups 1,2,and 3,respectively（P〈0.001）.The median AL（mm） in right eyes were 10.65（10.00,11.10）,9.90（9.70,10.00）,and 9.20（9.15,9.25） in groups 1,2,and 3,respectively（P〈0.001）.The median delta-delta cycle threshold（CT） values for the VIP2 receptors were 1.07（0.82,1.43）,1.22（0.98,1.65）,0.29（0.22,0.45） in right eyes of groups 1,2,and 3,and 1.18（0.90,1.37） in left eyes of group 1,respectively（P=0.001）.The median delta-delta CT values for the ZENK protein were 1.07（0.63,5.03）,3.55（2.20,5.55）,undetectable in right eyes of groups 1,2,and 3 and 1.89（0.21,4.73） in left eyes of group 1,respectively（P=0.001）.CONCLUSION： VIP has potential inhibitory effects in the development of FDM.

Transmittance Spectrum of Unbranded Sunglasses Using Spectrophotometer

引用

Open Journal of Ophthalmology 2015年第1期5卷 1-5页

作者： Huseyin Gursoy hikmet basmak Hamza Esen Ferhan Esen Eskisehir Osmangazi University Medical Faculty Department of Ophthalmology Eskisehir Turkey Eskisehir Osmangazi University Medical Faculty Department of Biophysics Eskisehir Turkey

Background: The sunglass standards are not strictly implemented in many countries except Aus-tralia. The purpose of the study was to evaluate the optical properties of unbranded sunglasses for light transmittance. Methods: Unbranded sunglasses with no information about their specifications were included. They were allocated to two groups based on their prices;the ones > 25 US$ (Group A) and the cheaper ones (Group B). Their transmittance spectrum was measured between 190 nm and 900 nm using a double beam scanning spectrophotometer. The European standard for sunglasses was used to evaluate their compliance regarding ultraviolet radiation (UVR) transmittance and minimum requirement for wearing when driving. Results: Thirty-eight sunglasses (Group A = 20 and Group B = 18) were evaluated. Four sunglasses in each group were non-compliant. Percentage transmittance of visible light was <8% in five sunglasses of Group A and in three of Group B, so these were not appropriate to wear when driving. Totally six sunglasses of Group A and five of Group B were non-compliant and/or inappropriate to wear when driving. Conclusions: Based on our findings about their UVR protection and visible light transmittance %, eye care professionals must warn people against the use of unbranded sunglasses without any information about their specifications.

Chinese Journal of Traumatology 2009年第5期12卷 -页

Orbitocranial penetrating injuries are uncommon and usually life threatening, which constitute about 0.4% of all head injuries, 24% of penetrating head trauma in adults, and 45% in children.1,2,3They may occur accidentally or due to an assault and may have serious consequences and can be potentially fatal.4,5 Immediate plastic and reconstructive surgery, ophthalmology and radiology consultations are essential for the proper diagnosis and treatment. We reported an adult patient with a transorbital cerebral injury by an unusual material---grinding wheel. To our knowledge, this is the first reported case of transorbital penetrating injury by a grinding wheel in the literature.
