BACKGROUND: Relative changes of astroglial volume constitute the major part of brain edema, which is related to delayed neuronal damage. Several factors including glutamate may contribute to astroglial swelling. Intravenous anesthetic, ketamine was known to restore neuronal damage by inhibiting NMDA receptor activity. Therefore, we decided to investigate the effect of ketamine on the astrocyte swelling by glutamate in the present study. METHODS: To analyze cell swelling in vitro, glial cell line, U1242MG was used. The effects of glutamate (1, 2, 3 mM), and glutamate with ketamine (1 mM) on the regulation of astrocyte volume were achieved by flow cytometry system. To eliminate the dead cells from experimental cell suspension and to assess cell viability, fluorescent dye propidium iodide was used. RESULTS: Glutamate addition (1, 2, 3mM) caused astroglial swelling both in calcium present and calcium absent buffer. The difference of cellular swelling dependent on glutamate concentration was only seen in calcium free buffer (p<0.05). Ketamine per se did not affect astroglial volume. However, when it was added to glutamate perfusion, 1 mM ketamine diminished cellular swelling by glutamate during first 10 minutes (p<0.05), and cellular shrinkage by glutamate after 1 hour incubation (p<0.05). CONCLUSIONS: Ketamine (1 mM) is effective in the regulation of astroglial volume alterations induced by glutamate in both short time and long time perfusion.

There are various methods to correct mild ptosis and to make a double fold. However, all pre-existing methods have similar disadvantages, such as long-lasting swelling and down time. Recently, many patients prefer more convenient and minimal invasive methods with faster recovery. So we have devised a new technique to correct mild ptosis. Our technique is very similar to other non-incisional stitch methods. We try to correct ptosis through Muller's muscle tucking using the non-incisional stitch method. We think this method could be applied to mild degree ptosis. We hope to report the long-term follow up data of our cases and analysis with more efficient technique in the near future.

Between Feb. 1992 and Apr, 1995, the authors have performed arthroscopic abrasion arthroplasty in 78 knees of 76 patients with degenerative osteoarthritis. The followup period was between 24 and 58 months, with on an average of 41 months. All patients had Zarins grade IV articular cartilage change. The results were as follows. 1. Of the total 78 knees, results were excellent in 25(32%), good in 33(42A), fair in 12(17%), poor in 8(10%) knees respectively. 2, The best results were obtained patellofemoral abrasion arthroplasty. 3. The poor results were obtained in patients with the both femoral condyle, lesion. 4. The results were much better in young age group (below 40 years). Aroscopic abrasion arthroplasty is not a curative but palliative method. But it could be an appealing altemative to total knee arthroplasty or high tibial osteotomy or can be performed postoperated after these reconstructive proeedures.

People increasingly prefer fast and convenient methods for aesthetic procedures in busy modern society. Therefore, physicians and patients increasingly desire to improve cases of mild ptosis of the eyes in a simpler way. The purpose of this review is to organize the surgical methods of minimal incisional ptosis correction that the author has developed to satisfy this need and to examine the indications of each method and its advantages and disadvantages. The basic technique is a triangular single-knot stitch method using five points. Additionally, the method of applying a special loop (tucking the Müller muscle by pulling the conjoint fascial sheath) and the method of combining a non-incisional method with making a loop will be explained herein.
