1.Postoperative Recurrence Rate of Superior-Inferior Sliding Conjunctival Flap and Mytomycin-C for the Treatment of Primary Pterygium.
Journal of the Korean Ophthalmological Society 1999;40(3):721-727
One of the major problems after pterygium removal are recurrence and complications of the adjunctive therapy. The author compared the recurrence rate, interval and age of the primary pterygium after surgical treatment and with(group 1:94 eyes) or without(group 2: 101 eyes) supple-mentary mitomycin-C therapy. All of whom had been treated by one surgeon using a pterygim and subconjunctival tissue removal and superior-inferor, sliding conjunctival flap to cover the pterygium defect, In group 1, supplementary mitomycin-C was topicall used. In group 1, three pterygia(3.2%) were recurred. Recurrence were more Likey after ealy polstperative wound disruption with flap retraction(2 of 3 recurrences), relativy uoung pationts(all recurrences are under 50), and recurrence occured at a mean interval of 3.8 months after surgery. In group 2, three pterygia(3.0%) were recurred. Recurrencd were monre likely after early postoperative wound disruption with flap retraction(all recurrences). young patients(all recurrences are under 45), and recurrence occured at a mean interval of 3.1 months after surgery. Between two group no significant difference in recurrence rate, age, and interval so pterygium surgical procedure, operator and early postoperative conjunctival flap state are more important factors than adjunctive therapy in recurrence.

The effect of saponin on the Na+ - K+ ATPase of anterior capsule and epithelium of cattle lens has been investigated. The experiment also designed to determine the cation of saponin on the Na+ - K+ ATPase activity in anterior capsule and epithelium of cattle lens. The following results are observed. 1. The Na+ - K+ ATPase activity of cattle lens epithelial cell membrane is inhibited by low concentration of saponin, but increased by high concentration. The strongest activity showed at the dose of 50mg% saponin concentration. 2. The activating effect of saponin on the cattle epithelial cell membrane Na+ - K+ ATPase activity is inhibited by ouabain, but the stimulation of the Mg++ ATPase by high concentration of saponin is not inhibited by ouabain. 3. The activity ratio of Na+ - K+ ATPase by high concentration of saponin is increased by raising the sodium concentration but decreased by raising the potassium concentration. 4. The Na+ - K+ ATPase activity is increased by small amount of calcium but completely inhibited by over 5mM concentration of calcium.

BACKGROUND: The keratinocyte growth factor(KGF) is a recently identified mitogen for epithelial cells produced by nomal stromal fibroblasts. ln the skin, KGF has been shown to stimulate keratinocyte proliferation and differentiatian. Dendritic epidermal T cells(DETC) are skin-specific members of the epithelial y 8 T-cell family that reside normally in the murine epidermis. The DETCs recognize antigen expressed by damaged or diseased neighboring keratinoctyes and consequently secrete cytokines sueh as IFN- y, lL-2, IL-4, GM-CSF. OBJECTIVE: The purpose of this study was to observe the expression of KGF mRNA in keratinocyte and DETC as well as to investigate the cytokine-mediated intercellular communication between kerati- nocyte and DETC. METHODS: Using a RT-PCR(reverse transcription-polymerase chain reaction), we examined the expression of KGF mRNA in keratinocyte and DETC, and compared the level of KGF mRNA between resting and activated DETC with Con-A (concanavalin A).

We report a case of subcutaneous fat necrosis associated with pancreatitis that may be the first case in Korean hterature as for we know. The patient was a 41-year-old man wbo presented erythema nodesum-like erythematous subcufaneous nodules on both lower extremities. Histopathologic findings showed subcutaneoms focal fat necrosis and ghoat-like cells. Granular basophilic material was deposited in and around the necrotic fat cells and stained positively with von Kossa stain. The lesioas subsided gradwdly without any specific treatment, as the underlying pancreatitis was ameliorated.

In order to prevent the development of central island after excimer laser photorefractive keratectomy(PRK), 547 eyes which had undergone PRK were studied to evaluate the incidence, width and height of central island retrospectively. Based on this result, PRK was performed on 63 eyes under conventional protocol(software version 3.20, VISX Twenty/twenty Inc, Santa Clara, CA) and then additional laser ablation with a correction amount of 2.5D and adiameter of 3mm was performed whether the incidence has been decreased and additional complications have occurred. As a result of conventional protocol, central island had occurred in 121 eyes out of 547(22.1%) and the width was 2.94+/-0.22mm and the height was 2.64+/-0.89D. In case of 63 eyes which underwent additional laser ablation, central island occurred in 4 eyes (6.34%) and overcorrection occurred only in 3 eyes(4.76%) at one month after PRK. From the standpoint of the above results, we reached the conclusion that the additional ablation for 2.5D by a 3mm in diameter after PRK under conventional protocol is effective. By using this method, we could reduce the incidence of central island without the aid of the upgraded version that contains the anti-central island program.

We report a case of porokeratosis of Mibelli coexistence with linear porokeratosis in a 28-year old male. He had multiple discrete reddish to brownish annular plaques with peripheral keratotic ridges on the left side of the neck and axilla, and such lesions extended in a linear fashion on the left side of the upper arm and posterior aspect of the lower extremity. The cutaneous lesions started on the left neck and axilla about 6 years prior to consultation. Two years after that, new lesions developed on the left side of the upper arm and lower extremity in a linear fashion. There was no family history of similar skin disorders. A histological examination showed cornoid lamellae in the horny layer. Hypogranulosis, dyskeratotic cells and perivascular mononuclear in-filtrations were also seen beneath the cornoid lamella.

7.The Change of the Intraocular Pressure and Blood Pressure After Exercise.
Journal of the Korean Ophthalmological Society 1986;27(4):567-571
The object of this study was to analyze the effects of exercise on intraocular pressure, blood pressure, and pulse rate. This study was performed in 60 eyes of 30 patients. The intraocular pressure, blood pressure, and pulse rate were taken before exercise, and after exercise for 5 minutes. The change of the intraocular pressure and blood pressure before and after exercise were compared using the t-test. The results of analysis were summarized as follows; 1. The mean of systolic blood pressure was 118.2 +/- 8.2 mmHg before exercise, 145.2 +/- 11.5mmHg after exercise. This change was statistically significant. 2. The mean of diastolic blood pressure was 77 +/- 6.1 mmHg before exercise, 90 +/- 8.3mmHg after exercise. This change was statistically significant. 3. The mean of pulse rate was 73 +/- 11.8/min. before exercise 103.3 +/- 14.4/min. after exercise. This change was statistically significant. 4. The mean of intraocular pressure was 17.41 +/- 1.6 mmHg in right eye 17.80 +/- 1.6rnmHg in left eye respectively before exercise, and 17.34 +/- 1.6 mmHg in right eye 17.64 +/- 1.6 mmHg in left eye respectively after exercise. This change was statistically insignificant. With the above results, we found no clear association between change of intraocular pressure and change of blood pressure after exercise.

Journal of the Korean Ophthalmological Society 1980;21(4):497-503
The author analysed statistically 221 cases of the ocular injuries, among 4056 out-and-in patients who visited to the Red Cross Hospital, during the period of 1979. 6. 1. ~ 1980. 5. 31. The incidence of ocular injuries was 5.4% of all patients. The incidence was exceedingly more common in male (76.5 %) and in the age of first to second decade (56.6 %). The ocular injuries were more common in the spring (33.1 %). Subconjunctival hemorrhage is a most common in the ocular injuries (21.8 %). Small flying particles, such as sand, dust, and iron piece, were most common causative agent of ocular injuries. At the first visit, 15.8 % of all cases were markedly decreased visual acuity and 2.5 % of all cases were not improved. The prognosis of the ocular injury is good with early adeguate management of trauma.

14-3-3 proteins are cytoplasmic proteins of about 29 kDa and have a minimum of seven isoforms. This protein is important in signal transduction with the ability of binding with phosphoserine of many signalling proteins. We expressed 14-3-3 protein tagged with 6 histidine residues in E. coli and purified the protein by nickel affinity chromatography. Using this purified protein as an antigen, we made rabbit antisera and mouse monoclonal antibodies to 14-3-3 zeta isoform. We subcloned cDNA of 14-3-3 zeta isoform derived from HeLa cell lamda gt 11 library into an E. coli expression vector which is designed to express heterologous protein with N- terminal 6 hidtidine tag. BALB/c mice were immunized with purified 14-3-3 protein and the hybridoma clones which produce monoclonal antibodies angainst 14-3-3 protein were selected. These monoclonal antibodies reacted with the recombinant protein expressed in E. coli as well as the 29-kDa native protein in various cell lines. However, they did not immunoprecipitate 14-3-3 protein. The monoclonal antibodies produced in this study can be valuable tools for the identification of the 14-3-3 in signal transduction study.

Annals of Dermatology 1999;11(1):13-18
BACKGROUND: The regular use of soaps and synthetic detergents has been associated with skin dryness and aggravation of dermatological conditions. OBJECTIVE: Our purpose was to investigate the irritancy of 10 hand dishwashing liquids on normal skin. METHODS: The skin changes, responding to repeat patch testing with 10 hand dishwashing liquids, were measured by visual scoring. RESULTS: The results are summarized as follows; 1. Of the 16 healthy volunteers 8 had reactions. 5 women and 3 men, but there was no significant difference in irritancy between men and women. 2. The mean irritancy scores of the 10 hand dishwashing liquids ranged from 0.06 to 0.88. 3. A prominent increase in the degree of erythema in the first 24 hour patch test did not persist beyond exposure day 5, but after day 5, augmented responses of the erythema and scales, even fissuring occurred. 4. The pH of the test solutions of the hand dishwashing liquids ranged from 5.0 to 6.0, but there appeared to be no correlation between pH and irritancy in the dishwashing liquids tested. CONCLUSION: Our data suggests that regular exposure to hand dishwashing liquids may cause disturbances of the skin in a substantial proportion of individuals, and workers should use hand dishwashing liquids in lower concentrations than recommended and only for short periods with protective measures.
