BACKGROUND: It is well known that neuronal degeneration can occur after a brief deprivation of energy source. To investigate whether glial astrocyte can induce a phenomenon of delayed cell death after transient energy loss and to see how different are the effects of nifedipine, lidocaine, carnosine and hypothermia on delayed toxicity in astrocyte. METHODS: Human astrocytoma cells (U1242MG) were used in this study. To assess the astrocyte survival during post-ischemic period after transient histotoxic hypoxia, 3-[4,5-dimethylthiazol-2yl]-2,5, diphenyl tetrazolium bromide (MTT) test was used. Compared to MTT test, tryphan blue test was also used to demonstrate membrane damage of affected cells. Studies on intracellular calcium dynamics during ischemic and post-ischemic period were carried out with fluo-3 and flow cytometry system. RESULTS: The percentage survival of astrocyte during post-ischemic period was decreasing with time. Calcium channel blocker nifedipine, sodium and calcium channel blocker lidocaine and free radical scavenger carnosine could not prevent post-ischemic cell damage. But, hypothermia was only an effective method in ameliorating post-ischemic cell death. Intracellular calcium increase during ischemia and post-ischemia was dependent on extracellular calcium influx. CONCLUSIONS: Only hypothermia was effective in reducing astrocyte death during post-ischemia after transient energy depletion. Intracellular calcium alterations during post-ischemia was from extracellular space.

Adenoid cystic carcinoma occurs most commonly in the salivary glands, and also has been recognized in numerous other locations. However, it is rarely found in the prostate. We report a case of adenoid cystic c arcinoma of the prostate in a 77-year-old man whose chief complaint was urinary retention. Digital rectal examination transrectal ultrasonography revealed a markedly enlarged prostated and PSA was 4.6ng/ml. The transurethral prostatectomy was performed and the histopathological diagnosis was the adenoid cystic carcinoma. We review the clinical and pathologic feature of this disease.

Patellofemoral complications are the most frequent problems in total knee arthroplasty. In the literature, the subject of patella resurfacing and nonresurfacing is controversial. Twenty-seven osteoarthritic patients who received bilateral total knee prostheses were studied to evaluate the advantages and disadvantages of patella resurfacing prospectively. Only patients with mild patellofemoral disease were included in the study. The Ortholoc modular implant was used in all cases. Cementless femoral and tibial component were used. But, if we resurfaced the patella, cement was used. In all patients, patella resurfacing had been done in the left knee but not in the right knee. For the clinical analysis, We used Knee Rating Score of the Hospital for Special Surgery(HSS), For the roentgenographic analysis, We used Laurin's lateral patellofemoral angle & Merchant's congruence angle. In the follow up, blind test for patellar pain was performed to compare between right and left knee joint clinically. The average age was 61 years(range 28-72 years) and the average follow up was 21 months(range 12-27 months). Preoperative ROM was 104.4 degrees in right side and 106.7 degrees in left side. Postoperative ROM was 112.7 degrees in right side and 109.6 degrees in left side. Preoperative HSS Knee Rating Score was 53.1 point in right side and 54.8 point in left side. Postoperative HSS Knee Rating Score was 81.5 point in right side and 81.2 point in left side. In the plain knee AP view, preoperative tibiofemoral angle was varus 7.0 degrees in right side and varus 5.6 degrees in left side. Postoperative tibiofemoral angle was valgus 5.1 degrees in right side and valgus 4.9 degrees in left side. Preoperative Merchant's congruence angle was 14.9 degrees in right side and 15.3 degrees in left side. Postoperative Merchant's congruence angle was

The paramount importance of breast feeding for the health of the infants has been recognized by untritionists and physicians. Although many advantages of the breast feedng, exclusive breast feeding without weaning diet or supplement food during prolonged perind in infants may produce iron deficiencyh anemia. This study was conducted to find out the hematologic state in exclusively prolonged breast-fed infants among these anemic patients and the way of thinking about their baby's feeding method in their mothers. Mothers of the anemic patients has been surveyed with questionare. The results and problems obtained from this study are summerized as follows. 1) Among 40 patients of this study, 27 were male (67.5%) and 13 were female (32.5%). Mean age was 12.6+/-2.7 month and 9 & 11 month of age were the most common, respectively (15.0%). 2) Mean age of mothers was 29.5 year. The 25 34 year-old group was most common. 3) Education levels of mothers were primary 10%, middle 10%, high 60%, and college graduate 20%. 4) In motivatins of breast feeding. Persuasion of husband or the parent of husband' 19(47.5%). 'Convenience for use' 12 (30.0%), and 'Through mass media or public information' 9 (22.5%). 5) In the causes of prolonged breast feeding, 'Think that satisfactory nutrition for baby is possible with breast milk alone' 4(10.0%), 'Due to persuasion of husband or the parents of husband' 11 (27.5%), 'Baby did no suck milk bottle or eat other diet except breast milk' 25 (62.5%). 6) In whether or not acknowledgment of the necessity of weaning diet, 'Know it but not consider so important 22 (55.0)%, 'Do not know at all) 15 (37.5%), and 'Breast milk, that will do' 3(7.5%). 7) Hb level in patient group, from 6 to 6.9g/dl was 2 (50.0%), from 7 to 7.9g/dl was 3 (7.5%), from 8 to 8.9%g/dl was 15 (37.5%), and from 9 to 10 g/dl was 20 (50.0%). From 9 to 10g/dl was the most common. Hematologic findings were Hb 8.8+/-0.9g/dl, Hct 28.8+/-3.0%, MCV 64.7+/-6.7 fl, MCH 20.0+/-2.5pg, MCHC 30.8+/-1.5g/dl. Platelet 452.5+/-142.9x103/mm3, Reticulocyte count 1.4+/-0.6%, Fe 28.6+/-14.1 g/dl, TIBC 446.7+/-66.2 g/dl, Ferritin 10.5+/-7.0ng/ml. Transferrin saturation 6.6+/-3.5%. 8) In association with duration of breast milk feeding and hematologic findings, as duration was prolonged, Hb, Hct, MCV & MCH were significantly decreased (p<0.01).

PURPOSE: The purpose of this research is to identify factors affecting suicidal ideation of the low-income elderly. METHODS: The study subjects were lowest-income(basic living allowance) and lower-income elders who were registered for home visiting services at five District Health Centers in Seoul. Interview data were collected from 280 elders and analyzed. Using SPSS/WIN 21, chi2-test and t-test were conducted to analyze the relationship between the subjects' characteristics and their suicidal ideation, and logistic regression was done to identify factors affecting suicidal ideation. RESULTS: Of the subjects, 48.6% had suicidal ideation for the last one year. Self-evaluated psychological status, quality of sleep, depression, and loneliness were affecting factors to the subjects' suicidal ideation. CONCLUSION: Psychological and social factors are strongly related to the suicidal ideation of the elderly who are living alone in metropolitan areas. Therefore, home visiting services should supply physical, psychological and social cares continuously to the low-income elderly, especially those who live alone in metropolitan areas.

A severe chemical or thermal injury is a troublesome ocular insult, which usually results in persistant corneal epithelial defect, stromal scarring, and neovascularization. For resurfacing chemically burned cornea, limbal autograft transplantation is presented in 2 cases of chemical and/or thermal injury with follow-up of 6, 8 months. The operative technique involved transfer of four free grafts of limbal tissue from the uninjured fellow eye to the severely injured eye. Clinical results of the cases have shown surface healing with stable epithelial adhesion without recurrent erosion or persistant epithelial defect.
