The Electrolyte Changes of Pig`s Lens in Experimentally Induced Cataract

Protein accounts for over one third of the human lens, the remaining two thirds being water. The other constotuents of the lens including lipids, amino acids, electrolytes and a variety of peptides and carbohydrates, account for about 1% of the lens wet weight. Since transparency of the lens is so highly dependent on protein order and structural integrity, it is not surprising that relatively small changes in any of these parameters might lead to the development of opacification resulting in a cataract.We have analyzed electrolytic differences between normal lens and lens of experimentally induced cataract to find the important factor in including cataract after we had extracted one hundred eight pig lenses. We divided these experimentally induced cataract into a group of normal lens capsule and another group of lenses which we performed with a 26 gauge needle. The sodium level was decreased in 15% mannitol solution and increased in normal saline. In every solution the potassium level was decreased. The chloride level was decreased in the 15% mannitol solution and increased in the normal saline solution. The calcium level also was decreased in mannitol and distilled water.Our results indicate that the potassium level of the experimentally induced cataracts decreased in any conditions and may be an important factor in inducing cataract.

Effect of adenoidectomy on dentofacial skeleton in naso-respiratory dysfunction children / 영남의대학술지

This study was made to investigate the effect of adenoidectomy on dentofacial skeleton in naso-respiratory dysfunction children. The clinical material compromised the 24 children in a previous study who had naso-respiratory dysfunction and 24 children who were the nasal breathing with normal occlusion. The cephalograms were taken at the initial examination and 1 year later for the control group and experimental group the paired sample statistical analysis was performed. The results were as follows. 1. In cranial base variable, difference between two groups were not statistically significant. 2. In craniofacial variables, experimental group showed brachyfacial pattern but control groups didn't show significant growth pattern. 3. In maxillary variables, experimental group showed flattening the plane. 4. In mandibular variables, experimental group showed the decrease of mandibular plane angle and gonial angle. 5. In facial height variables, experimental group showed horizontal growth rotation.

Argon Laser Treatment of Trichiasis

Recurrent trichiasis is a persistent annoyance and, too often, resists conventional treatment. We tried the application of argon laser in the treatment of trichiasis. The technique involves the destruction of the follicles of the abnormal cilia. This method proved safe, convenient, precise, and effective in 6 cases out of 6. The technique is most suitable when a few fine cilia are involved, but repeated treatment may be required for more and thicker eyelashes.

Treatment of Macular Hole Retinal Detachment with Intravitreal Gas

Exchanging liquid vitreous with an air bubble was used to treat the eye with retinal detachment caused by a myopic macular hole. This retina was successfully reattached after keeping the patient in a prone position for 24 hours. No cryotherapy, diathermy, or photocoagulation was used to creat a choroidal adhesion. This procedure may be the treatment of choice in patients with retinal detachment due to macular holes but withour other breaks or visible vitreous adhesion.

The Effect of Mouth Breathing Due to Nasopharyngeal Obstruction by Adenoids on the Tongue, Mandible and Hyoid Bone Position / 영남의대학술지

This study was made to investigate the influence of mouth breathing to tongue, mandible and hyoid bone position. It has been clinically suggested that the mouth breathing is induced by the respiratory dysfunction of nasopharyngeal airway causing by the Adenoids. The author used the 50 children, who were the nasal breathes with normal occlusion as the control group, and 50 children, who were mouth breathers with Adenoid as the experimental group. Results were as following: 1. In experimental group, the tongue was positioned more anterior and lower than that of the normal children. 2. In experimental group, the mandible was positioned more lower than that of the normal children. 3. In experimental group, the hyoid bone was positioned more anterior and lower than that of the normal children.
