There had been a continuous evolution of lymphoma classification and recently a Revised European-American Lymphoma Classification was proposed by the International Lymphoma Study Group. This new classification often requires information on immunophenotypic and molecular biologic markers in addition to the usual histologic findings. Recent advances in the production of commercially available monoclonal antibodies reactive on formalin-fixed paraffin-embedded tissues provide us a great help to classify the non-Hodgkin's lymphoma. We have analyzed 31 low grade B-cell lymphomas by the schemes proposed by the International Lymphoma Study Group using antibodies to CD3, CD5, CD20, CD23, CD43, cyclin D1, and bcl-2 protein, and have analyzed the immunophenotypic features. Among 31 low grade B-cell lymphomas, 8 small lymphocytic lymphomas, 5 mantle cell lymphomas, 7 follicle center lymphomas (2 grade I, 3 grade II, and 2 grade III), and 11 marginal zone B-cell lymphomas (all of which were extranodal) were identified. Among 8 small lymphocytic lymphomas, 5 cases were positive for CD5; 6 cases were positive for CD23; 7 cases were positive for CD43; all 8 cases were negative for cyclin D1; and 7 cases were positive for bcl-2. Among 5 mantle cell lymphomas, 4 cases were positive for CD5 and CD43; all five cases were negative for CD23; 4 cases were positive for cyclin D1 and bcl-2. All 7 follicle center lymphomas were negative for CD5, CD43 and cyclin D1 and 2 cases were positive for CD23; and 6 cases were positive for bcl-2. All marginal zone B-cell lymphomas were negative for CD5, CD23 and cyclin D1; 3 cases were positive for CD43 and 9 cases were positive for bcl-2. Diagnostic utility for CD5 antigen detection on paraffin embedded tissue has a limitation due to weak antigen expression in tumor cells of B-cell lymphomas; however, still be useful in differentiating small lymphocytic lymphoma and mantle cell lymphoma from other B-cell lymphomas when applied in conjunction with CD43. CD23, CD43, and cyclin D1 appear to be of great help in differentiating subgroups of low grade B-cell lymphomas. Bcl-2, as known, is found to be useful to rule out reactive follicular hyperplasia.

The purpose of this study was to investigate effects of nutrition education program and pamphlet for the lower grades elementary students focused on individual daily needed food exchange units using Food Exchange System. Program consisted of four lessons (40 min/lesson), "5 major nutrients & function", "6 food group and sources", "daily needed food exchange units for normal body weight", and "smart snack choice and exercise". Pamphlet as activity book was developed for the program. The subjects were 3rd grade elementary students (educated group, 31 vs. non-educated group, 31). Educated group were lessoned as group and/or individual. We examined the differences in nutrition knowledge, dietary attitudes, dietary intakes and satisfaction of the program and pamphlet. In educated group, there were positive improvements on nutrition knowledge score "function and foods of 5 nutrients" and on dietary attitudes "type of breakfast and snacks". In the evaluation of dietary intakes according to KDRI, there were positive improvements on intakes level of riboflavin, vit. C, folate, Ca, P, Fe and Zn in educated group. In satisfaction with the program and pamphlet, contents, font size, visual, figure, difficulty and program curriculum were over 2.90/3.0. It showed that the developed nutrition education program and pamphlet focused on individual daily needed food exchange units using Food Exchange System improved nutrition knowledge, dietary attitudes and nutrients intake level in the lower grades elementary students.

The angiotensin I converting enzyme inhibitor (Captopril) has recently been studied extensively in various experimental models of radiation injury and has proven its protective effects in various organs, such as the lungs, gastrointestinal tract, and kidneys. Twenty-three Sprague-Dawley rats were divided into experimental and control group. The experimental group was divided into two large groups: the first one received a single dose of 18 Gy irradiation from an electron beam on the local field of the kidney region only, and the second group received captopril per oral continuously after the same doses of irradiation. The second experimental group was divided into four subgroups by captopril doses: 62.5 mg/l, 125 mg/l, 250 mg/l, and 500 mg/l, respectively. On light and electron microscopy, the kidneys of the irradiated rats with no captopril treatment showed diffuse glomerular contraction, congestion with occlusion and focal necrosis of the endothelial, and mesangial cells. The tubules showed ballooning degeneration, desquamation, and diffuse coagulation necrosis. Captopril treated rats, especially those given a high dose (more than 250 gm/l), revealed a marked reduction of the tubular and glomerular injuries. There was a statistically significant difference in the degree of renal injury among the experimental groups (p<0.05). The result of this study suggests that an administration of high dose captopril might prevent radiation-induced renal injury, especially in the early post-irradiation period.

The serum value of immunoglobulin E (IgE) in 47 cases of atopic dermatitis and 43 cases of urticaria were determined by Phadebas PRIST(R) method in department of dermatology at National Medical Center, from Jan., 1982 to Sep., 1982. The results were as follow; 1. The mea,n IgE value in atopic dermatitis was significantly higher (408+/-l43 u/ml) than that of normal subjects (p>0.01). 2. The mean value of IgE in urticaria (310+/-299 u/ml) was not significantly higher than tha,t of normal subjects (p>0.05). 3. The rnean value of IgE in severely expanded atopic dermatitis (664+/-404 u/ml) was significantly increased than that of normal subjects (p>0.01) 4. The mean value of IgE in 7 cases of atopic dermatitis with allergic respiratory diseases (817+/-233 u/ml) was significantly elevated (p>0.01). 5. No close correlation was seen between IgE value and eosinophilia. 6. IgE in 2 cases of the urticaria infested with PW, CS were extended over 1000u/ml.

Eighty cases of malignant effusion were cytologically studied to elucidate the incidence of primary tumor site and cytologic characteristics of each tumor types. Eighty fluid specimens were composed of 43 ascitic, 35 pleural, and 2 pericardial effusion and primary tumor site had been confirmed by histology. The frequent primary sites were stomach (22 cases, 28%), lung (21 cases, 26%), ovary (11 cases, 14%), liver (7 cases, 9%), and breast (4 cases, 5%). The principal malignant tumors were adenocarcinoma (56 cases, 70%), squamous cell carcinoma (7 cases, 9%), liver cell carcinoma (7 cases, 9%), small cell carcinoma (4 cases, 5%), and non-Hodgkin}s lymphoma (4 cases, 5%). The distinctive cytologic findings according to primary tumor types were as follows ; the gastric adenocarcinomas were mainly characterized by isolated cells and irregular clusters sometimes with signet ring cells. Papillary serous cystadenocarcinoma of ovary showed frequently papillary clusters and occasional psammoma bodies. Breast carcinoma of ductal type showed cell balls with smooth margins. Colonic adenocarcinoma showed rather irregular clusters or palisading pattern of cylindrical cells. Metastatic squamous cell carcinoma, liver cell carcinoma, small cell carcinoma, and non-Hodgkin}s lymphoma showed also characteristic features. These findings indicate that the cytological features observed in the great majority of malignant effusion are similar to those of primary tumor types, which are very helpful to indentify the primary tumor site.

PURPOSE: Persistent pulmonary hypertension (PPHN) of the newborn has been treated with some vasodilators including tolazoline. But these drugs have many side effects, especially systemic hypotension . To investigate the usefulness of the nitroglycerin as a specific vasodilator with few side effects, this study was done. METHODS: Nitroglycerin was administered within 1st one day after birth in 8 newborn infants who were diagnosed as PPHN by echocardiography. They were born at Il Sin hospital from March 1994 to March 1996. Nitroglycerin was started as 2microgram/kg/min and its maximum dose was 6microgram/kg/min. Muscle relaxants and inotropic drugs were used together in all cases. Arterial blood gas analysis, systemic blood pressure, heart rate, renal function and electrolyte were checked in all patients. Alveolar-arterial oxygen difference (AaDO2) and oxygenation index (OI) were measured. RESULTS: 6 cases (75%) survived but 2 cases expired due to air leak.1) Basal mean AaDO2 was 631.4+/-21.7mmHg. It decreased to 493.9+/-1453.1 mmHg at 10hr after loading infusion and to 373.6+/-217.7mmHg at 48hr (P<0.05). 2) Basal mean OI was 35.1+/-15.7 and it decreased significantly to 12.6+/-14.8 (P<0.05) at 10hr. 3) There was no significant hypotension in systolic, diastolic and mean blood pressure during treatment of nitroglycerin. 4) There was no significant change in renal function, serum electrolyte and heart rate during treatment of nitroglycerin. CONCLUSIONS: Nitroglycerin produced systemic venodilatation and pulmonary arterial dilatation at the dose that produce only minimal systemic arterial dilatation. Nitroglycerin is an effective and safe drug in the treatment of PPHN.
