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.

Microsurgical reconstruction is necessary for children to correct severe trauma and congenital or acuqired deformity. The aim of this study was to evaluate whether or not microsurgical reconstruction is a safe and reliable operation in children and to analyze the differences of microsurgical reconstruction in children compared to adults. The study included 12 children who underwent 13 microsurgical reconstructions among a total of 251 cases of microsurgical reconstruction from May, 1986 to August, 1998. Their ages ranged from 24 months to 14 years and 8 months. There were 7 males and 6 females. The involved sites were 9 legs, 3 hands and 1 face. The causes of microsurgical reconstruction were 9 traumas, 2 congenital anomalies, 1 acquired deformity and 1 cancer. The applied flaps were 4 scapular flaps, 2 rectus abdominis muscle flaps, 1 de-epithelized groin flap, 1 lateral arm flap, 1 forearm tendocutaneous flap, 1 forearm tendocutaneous flap, 1 latissimus dorsi muscle flap, 1 fibula flap, 1 second toe transfer, and 1 wrap-around flap. All patients have had normal growth of the donor and recipient sites without specific complications during an average 2 years follow-up. We concluded that microvascular reconstruction is a very useful and reliable procedure in children if it is performed in consideration of each child's specific characteristics and conditions.

The authors analysed statistically 186 cases of the glaucoma patients among 20,785 out-patients who visited to our eye clinic from Jan. 1957 to Dec. 1969. The incidence of the glaucoma was 0.895% which was remarkably lower than the other reports. The following results were obtained. 1) Among the 186 cases, there were 85 male and 101 female patients. 2) There was no significant difference in left and right eye. 3) 51-60 year age group was prevalent (49 cases). 4) The age group over 40 occupied 61.3%. 5) The open angle glaucoma was the highest incidence.

A 7 day old female baby suffered from perinatal asphyxia and trauma at birth. Subsequently, she had a violeceous subcutaneous plaque on back. The clinical setting, the skin manifestation and the histologic findings of the lesion were diagnostic of subcutaneous fat necrosis of the newborn. Histologic findings revealed fat necrosis with infiltration of inflammatory cells, foreign body giant cells and several fat cells contain needle shaped cleft in radial arrangement. Four weeks latter, the skin lesion was healed spontaneously.

Cow milk allergy can be defined as an adverse immunologic reactions to cow milk protein. The term is often mistakenly applied to other causes of milk intolerence, such as lactase deficiency and galactosemia, which must be differenciated and excluded. We have experienced 10 children of cow milk allergy at neonatal onset who had suffered from G-I symtoms, such as diarrhea, irritability, weight loss, vomiting and abdominal distension. One half of this patients had family history of allergic diseas. All patients have positive specific IgE RAST to cow's milk protein, milk elimination test and milk challenge test. Brest milk feeding and soy bean formula feeding and soy bean formula feeding have started after diagnosis and then gastrointestinal symtoms and signs of all patients are improved but other allergic diseases are combined in 5 children.

This report is a clinical analysis and comparative study with previous report of bronchial asthma at National Medical Center on bronchial asthma in children who were admitted to the MP dept. of national Medical Center from January 1987 to December 1990. The results of the study were as follows: 1) The out-break ratio of bronchial asthma is 3.7% of hospitalized children which is no change that about 4% since 1980. 2) The children under 6 years of ge was 62.7% which among under 3 years was 33.1%. The rate of under 3 year children is increased as previous study. 3) The out-break of bronchial asthma was most common in September and October and so peak incidence was noted in fall and duration of hospitalization was most 2 week. 4) Familial allergic history was positive in 54.6% and bronchial asthma was most common. The presence of allergic past history was 52.2%) and atopic dermatitis was most common 5) Eosinophilia was found in 80.8% and elevated IgE was also in 61.6% of bronchial asthma. 6) We could get positive results of IgE RAST and skin test: D. pteronyssinus, D. farinae, Houst dust. 7) The most frequent findigs of the chest radiograph were within normal limits. 8) The clinical improvement rate of bronchial asthma is 52.5%.
