Quality control survey was done on the plasma triglyceride determination of six laboratories and following results were obtained. 1) Coefficients of variation were less than 5% in 3 laboratories and over 10% in one laboratory. 2) High interlaboratory variation was inferred from the mean values ranging from 104.0~136. 4mg% (sample A) with enzyme method and 44.7~65.3 (Sample B) with acetylaceton method. 3) Establishment of normal plasma triglyceride level in Koreans and supervised quality control by the authority seemed to be urgent.

To determine the types of metabolic a cidosis using anion gap in acute infantile diarrhea and to correlate it with clinical outcome, we examined 103 infants admitted with acute diarrhea. The serum electrolytes (sodium, potassium, chloride, phosphorus), creatinine, CO2 content and anion gap were measued on first admission day. They were classified group A with normal anion gap (8~16mEq/L) and group B with increased anion gap (>16mEq/L). The results were as follows. 1) The number of group A with normal anion gap (11.6+/-3.3mEq/L) was 62 and the number of group B with incresed anion gap(21.1+/-5.5mEq/L) was 38. 2) The duration of diarrhea was significantly prolonged in group B (9.0+/-2.5 days), compared with group A (5.9+/-1.1 days)(p<0.001). 3) The duration of admission was significantly prolonged in group B(5.6+/-2.2 days), compared with group A (4.+/-01.4days)(p<0.001). 4) Infants in group B, compared with group A, were significantly more severe dehydrated (p.

PURPOSE:Craniopharyngioma is one of the most common causes of organic growth hormone deficiency leading to pituitary hormonal insufficiency. However, some growth hormone(GH)-deficient children with craniopharyngioma may grow normally or even show accelerated growth. This study was designed to evaluate several factors associated with growth of patients with craniopharyngioma. METHODS:Forty children operated on for craniopharyngioma were evaluated for their pituitary function, serum insulin like growth factor-I(IGF-I), serum insulin like growth factor binding protein-3(IGFBP-3) and serum prolactin levels. We also observed their growth status and corresponding changes with or without GH treatment. RESULTS:Among 40 patients, one had normal pituitary hormonal status and one had isolated GHD(GH deficiency). The other patients showed multiple pituitary hormone deficiency including GH(98%), LH, FSH(75%), TSH(65%), ACTH(62%), and ADH(38%) deficiencies. Patients with GHD were categorized into 2 groups. Group 1 consisted of children who showed normal growth, thus had not received GH treatment(n=14) and Group 2, those who showed subnormal growth(n=25). Patients in Group 2 were subdivided into Group 2A, when the patients had not received GH treatment in spite of subnormal growth(n=9) and Group 2B, when GH treatment had been added later on(n=16). There were no differences in the age at diagnosis of GHD, initial height standard deviation score(Ht SDS), body mass index(BMI), peak GH concentration between Group 1 and Group 2. Height velocities in Group 1, 2A, and 2B were 8.1+/-.2 cm/yr, 2.4+/-.2 cm/yr, 2.7+/-.2 cm/yr during the first year of endocrinologic follow-up, 7.1+/-.8 cm/yr, 1.2+/-.1 cm/yr, 7.6+/-.7 cm/yr during the second year, 5.9+/-.0 cm/yr, 2.8+/-.9 cm/yr, 7.3+/-.7 cm/yr during the third year, respectively. BMI changes during the first year of endocrinologic follow-up and postoperative prolactin levels were not significantly different between Group 1 and Group 2A. Postoperative IGF-I and IGFBP-3 levels in Group 1 were significantly higher than those in Group 2A(P<0.05). Both IGFBP-3 and prolactin levels correlated significantly with height velocity in Group 1 and 2A(P=0.004 r=0.64 and P= 0.035 r=0.74 , respectively). CONCLUSION: In this study, growth in children with craniopharyngioma was likely to be associated with IGF-I, IGFBP-3 and prolactin levels. Further studies are needed to unravel other growth promoting factors related to GH independent growth.

9.A Study on the Effect of Topical Indomethacin on Sunburn.

It is generally recognized that several chemical mediators are involved in tbe pathogenesis of sunbum; however, the exact mechanism is still to he resolved. Recently, prostaglandin has been found to be one of the inflammatory mediators in sunbum, particularly in the delayed erythema response and several investigators have shown that the nonsteroidal antiinflammatory drugs inhibit the in vivo synthesis of prostaglandin. On the assumption that the nonsteroidal antiinflammatory drugs might exert a beneficial effect on the sunbum through the antiprostaglandin effect, several authors have reported the effect of indomethacin on sunbum. This study was undertaken to evaluate the effect of topical indomethacin on the delayed erythema response induced by artificial sunlamp and sunlight by clinical and histopathological examination. Indomethacin(2. 5% ointment, 2. 5% solution, 5% solution) was applied immediately after 3 MED irradiation of artificial sunlamp to the shaved back skin of 6 healthy albino guinea pigs weighing 550-850gm and 9 human volunteers and the delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours after irradiation respectively. Punch biopsies of the skin were performed on 6 guinea pigs at 6, 12, 24 a.nd 48 hours after irradiation and the histologic changes were observed. Four human volunters were exposed t,o 3 MED of sunlight and indomethacin preparations were applied immediately after irradiation. The delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours postirradiation and in one volunteer, the skin was biopsied at 24 hour for histologi.c evaluation. The results were as follows: 1. Topical indomethacin in ointment or solution forms delayed and decreased the appearance and degree of erythema induced by sunlight and artificial sunlamp in both human and animal subjects. 2. Histologically, the number of sunbum cells at 24 hour in the epidermis of one human volunteer was decreased on indomethacin applied sites. The dermis showe6 no difference in histologic changes between control and indomethacin sitea. In animal study, however, no detectable difference in epidermal or dermal changes was observed between control and indomethacin applied sites. The autors confirmed that topical indometha,cin was effective in delaying and blanching of the delayed erythema of sunbum in guinea pigs as well as in human volunteers, though there was no difference in histologic changes between indomethacin and control sites in guinea pigs. The mechanism involvel on this aspect is remained to be resolved.
