We performed tendon transfer with a microvascular free flap for recovery of handicapped function and reconstruction for the skin and soft tissue loss. We review the clinical data of 11 children who underwent these operation due to injured foot by pedestrian car accident from January, 1986 to June, l994. The mean age of patients was 5.6 years old (3-8). Five cases underwent tendon transfer and microvascular free flap simultaneously. Another 6 cases underwent operations separately. The time interval between tendon trasnfer and microvascular free flap was average 5.8 months (2-15 months). The duration between initial trauma and tendon transfer was average 9.6 months (2-21 months). The anterior tibial tendon was used in 6 cases. Among these, the technique of splitting the anterior tibial tendon was used in 5 cases. The posterior tibial tendon was used in 3 cases and the extensor digitorum longus tendon of the foot in 2 cases. Insertion sites of tendon transfer were the cuboid bone in 3 cases, the 3rd cuneiform bone in 3 cases, the 2nd cuneiform bone in I case, the base of 4th metatarsal bone in I case, and the remnant of the extensor hallucis longus in 3 cases. The duration of follow-up was average 29.9 months (12-102 months). The clinical results were analyzed by Srinivasan criteria. Nine cases were excellent and 2 cases were good. The postoperative complications were loosening of the tranferred tendon in 2 cases, plantar flexion contracture in l case, mild flat foot deformity in I case and hypertrophic scar in 2 cases. So we recommend the tendon transfer with a microvascular free flap in the case of injured foot of children combined with nerve injury and extensive loss of skin, soft tissue and tendon.

To evaluate and compare the clinical results of implantation of the AcrySof(r) with Hydrophilic Acrylic IOLs in early postoperative period(to 2 months), we retrospectively analyzed 34patients who had taken clear cornea incision and had been implanted with AcrySof(r)IOL in one eye and Hydrophilic Acrylic IOL in the other eye. There were no stastically significant difference in postoperative best corrected visual acuity, preoperative and postopearative astigmatic changes between AcrySof(r) and Hydrophilic Acrylic IOLs. But, the rates of postoperative capsular fibrosis and contracture of Hydrophilic Acrylic IOL was higher than those of AcrySof(r) IOL as well as postoperative complications. In conclusion, in the degree and rate of after-cataract, AcrySof(r)IOLs are more useful than Hydrophilic Acrylic IOLs. ;therefore, more excellent in long term visual prognosis. Further studies will be needed for the evaluation of clinical safety and efficacy.

This study was performed in order to recognize the identifications of the glycoproteins containing oligosaccharides in human gingiva. After made paraffin sections of human gingiva at 4µm, the sections were incubated with 7 lectins (UEA-I, BS-I, SBA, DBA, WGA, PNA, PNA after neuraminidase treated, Con-A). In order to increase specificity of reactions, the sections were applicated with ABC system. And then the sections were incubated with DAB and were counterstained with hematoxylin. Using the same sections, the sections were done H-E and PAS stains. In WGA, DBA and Con-A, plasma membranes of the layers of all epithelium and connective tissue were stained. In BS-I ; In the epithelium of marginal gingiva, plasma membranes of upper layer of the spinous cell layer and granular cell layer were stained. And in epithelium of sulcular gingiva, plasma membranes of the all spinous cell layer and granular cell layer were stained. In SBA ; Plasma membranes of the granular cell layer were stained. In PNA ; In the epithelium of marginal gingiva, plasma membranes of the basal cell layer and lower layer of spinous cell layer were stained. But lectin reactions were not occurred in thc sulcular gingiva. In PNA treated neuraminidase, plasma membranes of the all epithelial layer except basal cell layer membranes especially cytoplasms of upper layer at the sulcular gingiva and connective tissue were reacted. 1.

We examined the anatomical position of the mental foramina in mandibles foramen normal adult Koreans. 1. The percentages obtained from the study of the relationships between the mental foramen and the lower teeth showed that the most common location was type lv in which the mental foramen lay at the apex of the second promolar. The foramen between thr apices of ice two premolars (type lll) and the foramen between the second premolar and the first molar (type v) occured often and less often rspectively and find no foramen mesial to the first premolar or at the apex of the first premolar and posterior of the first molar (type l, ll, vl). 2. The study of relationship of the mental foramen to the bo of the mandible revealed that mental foramen was situated closer to the lowed border of the mandibular body. The distance ratio between the mental foramen and the alveolar crest to that between the mental foramen and the lower border was approximately 1.2 : 1. The height of the mandibular body was 31.09±2.80mm on the left side and 30.97±2.48mm on the right. 3. The distance from the mandibular symphysis to the anterior border of the mental foramen measured 29.52±2.01mm on the left, 30.82±2.04mm on the right side, and from the mandibular symphysis to the posterior border of the mandibular ramus was 104.20±4.74mm on the left, 105.44±4.49mm on the right side. It indicates that the mental foramen lies approximately at one-fourth of the distance from the mandibular symphysis to 2017-04-19 the posterior border of the ramus. 4. The distance from the superior border of the mental foramen to the bottom of the lower second premolar socket was found to be positive. It was 5.46±3.09mm on the left, 5.73±3.03mm on the right side. This indicates that the bottom of the lower second premolar socket is slightly higher than the superior border of the mental foramen.

To evaluate antioxidative effect of vitamin E, selenium and zinc sulfate on release of oxygen free radicals from polymorphonuclear leukocytes[PMNs], I measured the amount of superoxide release from human PMNs stimulated by phorbol myristate acetate[PMA]with addition of some antioxidant and antioxidative micronutrients using superoxide-dependent cytochrome c reduction.And to determine a protective effect of them on cultured bovine retinal pigment epithelial cells [RPE]from oxygen radicals, I measured a viability of bovine RPE using MTT assay after incubation with human PMNs and PMA. Vitamin E, selenuim and zinc sulfate are utilized at different concentrations of 1, 10 and 20 microM. Vitamin E and zinc sulfate inhibited superoxide production from PMNs stimulated by PMA from 10 microM concentration gnificantly. But in case of selenium, significant antioxidative effect was not found at each concentration.The antioxidative effect on cultured bovine RPE was evaluated using MTT assay.Among antioxidant and antioxidative micronutrients tested, vitamin E and zinc sulfate inhibited free radical damage to bovine RPE, they increased cell survival rate on culture at concentration of 1, 10 and 20 microM. In contrast, selenium did not increase cell survival rate significantly. With these results, it was found that vitamin E and zinc sulfate had antioxidative effect against superoxide release from PMNs and also protective effect of bovine RPE from free radical damages.Recent studies supported that peroxide may play an important role in causing tissue damage in human and experimental models of ocular inflammation and possibly in Behcet`s disease.It was suggested that antioxidant vitamins and minerals like vitamin E or zinc sulfate might be useful for management and/or prevention of these conditions.

In order to survey the reality of anxiety and depression among the Koreans residing in china, a study was conducted between January and March of 1991, on the residents of Yun-Kil city, with subjects of 472 Koreans and 479 Chinese. The evaluation was based on the questionnaires, named Combined self-rating anxiety depression scale (CADS), distributed among the subjects. ANOVA and t-test were applied for data processing. The results were as follows: There was not significant difference in the mean of total scores between the two groups. The scores of Koreans were 29.70±7.03, while those of Chinese were 29.45±9.01. The score of the CADS above 50 (clinically significant level) was seen in 12 (2.54%) Koreans and 21 (4.38%) Chinese. The anxiety-depression scores relating to the items of indigestion and decreased appetite, sleep disturbance, apprehension, decreased libido were relatively high among the Koreans. The items appeared low in scores among the Koreans were faintness, fear, suicidal rumination, hopelessness, paresthesias. The highs among the Chinese were facial flushing, anxiousness, dissatisfaction, suicidal rumination. The items appeared low among the Chinese were fear, faintness, paresthesias, weight loss, suicidal rumination. In the compatison of evaluation by items between the two groups, the items placing the Koreans significantly higher over the Chinese are indigestion & decreased appetite, sleep disturbance, apprehension, decreased libldo. The Chinese marked significantly higher in facial flushing, anxiousness, dissastisfaction, suicidal rumination. Those in the case of female (p<0.01 respectively), less than twenty years old (p<0.01 respectively), dissatisfied with family relationship (p<0.01 respectively), with past history of psychiatric hospitalization (Koreans p<0.01, Chinese p<0.05), pessimistic toward future, present, past self image (p<0.01 respectively) had significantly higher scores in both groups. In religion, neither group showed significant difference. In religion, neither group showed significant difference. In marital status, the Koreans showed a higher degree of divorce and separation and the Chinese in singleness (p<0.01 respectively). The Korean were higher in illiteracy and the Chinese had more college education (p<0.01 respectively). In place of growth, The Koreans showed not much difference in the areas while more Chinese grew up un large cities (p<0.01). More Koreans lived in the dormitory while the Chinese were engaged more in self-cooking (p<0.01 respectively), In pocket money per mouth, more Koreans were less than 1 dollar while the Chinese were between 7 and 10 dollars (p<0.01 respectively). There were no significant difference between two groups about religion.
