Streptomycin 은 아직까지 가장 동물체에 안전한 항생물질로 알려져 왔으나, BROWNLEE와 BUSHBY (1948)에 의하면 백혈구가 Streptomycin 처리에 의해 죽는다고 하였다. 본인등은 Streptomycin을 처리한 흰쥐의 백혈구수의 변화와 백혈구 지체의 운동능에 미치는 영향을 조사하였다. 치사를 이르키게하는 최저를 이내인 10mg, 5mg, 2mg. 1mg. 0,5mg을 각각 흰쥐에 주사한 후 일정한 시간내의 백혈구수의 변화를 보면 처리후 1시간에서부터 6시간 사이에 백혈구수가 급격히 감소하며 정상지인 12,000에서 최하 3,000수까지 내려간다. 감소하는 정도는 처리량의 다소에 관계없이 대개동일하게 일어나는 것이다. 감소하는 원인을 추구하고저 쥐의 미부로부터 탐혈하여 이에 Streptomycin을 직접 접촉시켜 백혈구의 운동능을 조사하였다. Streptomycin의 량에 tt례하여 백혈구의 운동속도는 저하한다. 일정량을 초과할 때는 백혈구는 단시간내에 죽는다. 처리량의 다소를 불문하고 일정한 정도로 수의 감소가 일어나는 것과는 달리 백혈구의 운동능은 량에 따라 많은 변화를 가져온다. 이것으로 보아 백혈구수의 감소와 운동능의 저하와는 특별한 관계가 없는 것으로 보며 백혈구수 감소의 원인에 대해서는 추후 실험에서 밝혀야 할 것이다.

청열조습(淸熱燥濕), 거풍살충(祛風殺蟲)의 효능이 있는 고삼(苦蔘)의 체내 면역활성에 미치는 영향에 대해 실험한 결과 아래와 같은 지견을 얻었다. ICR 생쥐에 고삼(苦蔘) 수침액을 투여한 결과 백혈구수 및 면역장기 변화는 없었다. in vitro실험에서 IgM PFCs에 유의성 있는 영향을 주지 못했고, BSA를 주사한 생쥐에서의 Arthus 반응에도 영향이 없었다. 그러나 지연형 과민반응을 억제하였으며, 비특이적 면역에 관여하는 macrophage의 탐식능을 약간 저하시켰다. 이상의 결과 고삼(苦蔘) 수침액(水浸液)은 세포성 면역을 억제하는 것으로 사료된다.

Purpose : Matrix metalloproteinase(MMP)-9 is known to breakdown the blood-brain barrier by degrading the extracellular matrix of the subendothelial basement membrane in meningitis. Tissue inhibitor of metalloproteinase(TIMP)-1, a known inhibitor of MMP-9, has been postulated to inhibit the proteolytic activity of MMP-9 by bindng to MMP-9, but their interaction has not been fully understood yet. So far, there have been some reports on the relationship of MMP-9 and TIMP-1 in bacterial meningitis, but few reports in viral meningitis. Furthermore, there has been no report on this in Korea. We investigated the concentrations of MMP-9 and TIMP-1 in cerebrospinal fluid (CSF) and serum of patients with viral meningitis and control subjects, and evaluated their relationship with other clinical parameters of meningitis. Methods : CSF and blood were obtained from 25 subjects with viral meningitis and 14 control subjects. After centrifugation, supernatants were stored at $-20^{\circ}C$ and we assayed concentrations of MMP-9 and TIMP-1 by the sandwich ELISA method. Results : Concentrations of CSF MMP-9 and TIMP-1 were significantly elevated in patients with viral meningitis, when compared with those in control subjects. Their serum levels showed no differences between the two groups. MMP-9 levels were closely correlated with TIMP-1 levels in the CSF($r_s=0.42$, P<0.05). CSF MMP-9/TIMP-1 ratios were significantly higher in patients with viral meningitis than those in the control subjects(P<0.05). Both CSF MMP-9 and TIMP-1 levels positively correlated with CSF total leukocyte counts($r_s=0.43$, P<0.05, $r_s=0.48$, P<0.05). TIMP-1 levels positively correlated with total protein concentrations in the CSF($r_s=0.43$, P<0.05). Conclusion : MMP-9 and TIMP-1 may play an important role in the breakdown and maintenance of BBB in viral meningitis, respectively.

The calcium balance study was carried out to determine the availability of calcium in different sources for chicks and laying hens. The sources of calcium were calcium carbonate (CC), dicalcium phosphate-dihydrate (DCPH), and dicalcium phosphate-anhydride (DCPA) for chicks and calcium carbonate (CC) and oyster shell (OS) for laying hens. The radioisotope dilution method was employed to measure the endogenous excreta calcium during the period of balance study following preliminary feeding. A. Experimental results with chicks: No significant difference was found among feed consumption of chicks fed diets containing different sources of calcium. Body weight gain of chicks was dependent upon the source of calcium. The gain decreased in the order of DCPH, DCPA and CC (P<0.01). The feed conversion efficiency in chicks fed DCPH was better than those in chicks fed CC or DCPA. The average tibia ash contents for chicks fed different sources of calcium were similar. The DCPH was superior to CC or DCPA regarding the calcium content in tibia ash. There were no significant differences among the average calcium contents in plasma trichloracetic acid filtrate in chicks irrespective of calcium sources. The mean apparent retention of calcium by chicks fed DCPH, CC and DCPA were 65.9, 64.0 and 59.9% respectively. The calcium to phosphorus ratios in tibia ash and plasma trichloracetic acid filtrate for chicks fed different sources of calcium were similar. The chicks fed DCPH showed the partition of endogenous excreta calcium in total excreta calcium as 35.6% which was higher than 31.0 or 31.4% for chicks fed CC or DCPA. The endogenous excreta calcium per day per chick in group fed DCPH, DCPA or CC were 17.2, 16.1 and 14.6mg respectively. The true retained calcium per day per chick in group fed DCPH were 109.9 mg which was higher than those observed with CC or DCPA group (P<0.01). The true retention of calcium by the birds fed diets containing DCPH, CC or DCPA were 78.1, 75.1 or 72.6% respectively. B. Experimental results with laying hens: The feed consumption, egg production and feed converion efficiency of laying hens fed diets containing different sources of calcium were similar. Calcium concentration in plasma trichloracetic acid filtrate in laying birds fed CC was equivalent to the value obtained by feeding OS. The apparent calcium retention by laying birds fed CC was 61.6% and it was significantly more than that of hens fed OS of 51.6% (P<0.05). The partition of endogenous excreta calcium in total excreta calcium of laying hens fed CC was 23.5% and this was higher than that of birds fed OS of 15.6%. The laying hens fed CC showed 310 mg of endogenous excreta calcium per day per bird while birds fed OS showed 261mg. The true retention of calcium by layers fed CC was 70.7% against 59.2% for birds fed OS (P<0.05).

Purpose : Cow's milk protein-induced enterocolitis(CMPIE) is a symptom complex of vomiting and/or diarrhea caused by delayed hypersensitivity and may result in serious complications. This study was undertaken to identify high risk factors to facilitate the early recognition of CMPIE. Methods : We reviewed the data of 101 patients, aged 15 to 45 days, admitted due to vomiting and/or diarrhea between 2003 and 2004. After excluding 13 patients absolutely breast-fed and 2 patients transferred from other hospitals with the impression of CMPIE, the 86 study subjects were divided into three groups based on the underlying etiologies; CMPIE, infectious and non-infectious group. Results : CMPIE was diagnosed in 11 patients(12.8%). On admission, failure to gain weight(P=0.003), hypoalbuminemia(P=0.003), peripheral leukocytosis(P=0.015), and metabolic acidosis(P=0.014) were more significant in the CMPIE group than in the others. Multiple logistic regression analysis showed that the independent predictors of high risks for CMPIE were failure to gain weight <10 g/day(OR, 10.25[95% CI, 1.62-65.06]) and serum hypoalbuminemia <3.5 g/dL(OR, 9.18[95% CI, 1.69-49.74]). Cow's milk challenges were performed in the 11 CMPIE patients; vomiting(81.8%), abnormal stool test(80.0%), peripheral leukocyte count and absolute neutrophil count(ANC) increase(100.0%) (P<0.05), and enteropathy(100.0%). Conclusion : CMPIE is not a rare clinical disease in early infancy. The high risk factors of CMPIE were identified as follow : failure to gain weight below 10 g/day, hypoalbuminemia on admission and a rapid decrease during admission. Cow's milk challenge test with endoscopic duodenal biopsy was helpful to confirm CMPIE.

Background : Isolated leukopenia is rare, but it has important clinical implications during antituberculosis treatment. Inadvertent discontinuation of short-course regimen drugs for fear of leukopenia inevitably will extend the duration of treatment, and the completion of treatment will be delayed. However no guidelines concerning proper management for leukopenia during antituberculosis treatment have been presented. Therefore, this study was performed to evaluate the possibility of continuing the same short-course regimen if a mild-to-moderate degree of isolated leukopenia was to develop during antituberculosis treatment. Method : Thirty-six patients who had been prescribed a short-course antituberculosis regimen between January 1997 and August 1999, had newly developed, mild-to-moderate degree, isolated leukopenia during medication, and had continued the same drug regimen despite leukopenia were enrolled. One patient was not available for the follow-up, so the remaining thirty-five (twenty-five prospectively and ten retrospectively) patients were analyzed. Patients who had other known causes of leukopenia were excluded. A mild-to-moderate degree of isolated leukopenia was arbitrarily defined as having a peripheral blood leukocyte count between 2,000 and $3,499/mm^3$ and no evidence of coexisting hematologic abnormalities. Results : 1) All thirty-five patients were able to complete short-course anti-tuberculosis treatment without complication or further decrease of leukocytes count to less than $2,000/mm^3$ despite continuous treatment with the same regimen. 2) The mean duration from start of antitituberculosis medication to detection of leukopenia was $64{\pm}65$ days. 3) The mean leukocyte count was $5,035{\pm}1,583/mm^3$ before treatment, and the its lowest count was $2,908{\pm}390/mm^3$ during treatment. Leukopenia recovered after completion of treatment ($4,283{\pm}1,269/mm^3$). 4) The main component of leukopenia was the decrease in neutrophil count ($3,361{\pm}1,732$ vs. $1,512{\pm}423/mm^3$, p<0.05). Conclusion : For mild-to-moderate degree of isolated leukopenia ($2,000/mm^3{\leq}$ WBC < $3,500/mm^3$), developing during short-course antituberculosis treatment, the short-course antituberculosis regimen may be continued without complications.
