461 cases of renal biopsy specimens were summerized correlated with their light microscopic and immunofluorescence findings, which obtained from Jan. 1981 to Jul. 1986 at Department of Pathology, Kyung Hee School of Medicine, The results were as follws: 1) The incidence of IgM nephropathy was about 5.8% of the primary glomerulopathy. 2) Sex distribution showed male preponderance with male: female ratio of 1.7:1. 3) Age distribution were 0-9 years 7.4%, 10-19 years 29.6%, 20-29 years 37.0%, 30-39 years 7.4%, 40-49 years 7.4% and 50-59 years 11.1%. 4) The clinical symptoms were gross hematuria 7.4%, microscopic hematuria 59.2%, proteinuria (nonnephrotic) 37.0%, nephrotic syndrome 55.5%, hypertension 7.8% and edema 59.2%. 5) 9 cases (33.3%) had past histories of upper respiratory infections. 6) The distributions of the light microscopic deagnosis were minimal histologic change 11 cases (40.7%), focal glomerulonephritis 7 cases (25.9%), measangial proliferative glomerulonephritis 5 cases (18.5%), focal and segmental glomerulosclerosis 1 case (3.7%) and poststreptococla glomerulonephritis 1 case (3.7%). 7) Immunofluorescence study showed significant diffuse mesangial granular deposits of IgM and C3 in all of the 27 cases. 8) It was demonstrated that in the patients with nephrotic syndrome, the prognosis for the patients with IgM deposition were less favorable than those without IgM deposition.

To evaluate the effect of allergic parameters, such as serum IgE, eosinophil, and skin test on the bronchial hyperresponsiveness (BHR) in patients with chronic airflow obstruction, we performed methacholine bronchial provocation test, pulmonary function test, skin prick test, and measured blood eosinophil counts and serum IgE level from seventy-nine patients who showed persistent fixed airflow obstruction, less than 75% of predicted value in FEV~ and FEV1/FVC, despite of conventional treatment without steroid therapy for more than 3 months. The results were as follows 1) There were 53 patients with BHR and 26 patients without BHR. There were no statistically significant differences in sex, age, and smoking duration between positive BHR group and negative BHR group (p>0.05). 2) There was no statistically significant difference in absolute and predicted value of FVC(p>0.05). But there were significantly lower absolute, predicted value of FEV1 and FEV1/FVC% in positive group compared with negative group (p<0.05). 3) There was somewhat higher trend of serum IgE level in positive group. Skin test was not significantly different between two groups (p > 0.05 ). 4) Blood eosinophil count was significantly higher in positive group than in negative group(p<0.05). Conclusion of this study is that increased bronchial responsiveness in patients with chronic airflow obstruction is inversely related to the level of pulmonary function and significantly associated with blood eosinophilia.

BACKGROUND: To evaluate airway responses and inflammation to antigen in Sprague-Dawley rat asthma model, we examined airway responses, serial histologic changes of the lung, and the relationship between airway responses and airway inflammation after antigen airway challenge. METHODS: Sprague-Dawley rats were sensitized with subcutaneous injection of 10 microgram ovalbumin(OA). Antigen airway challenges were done 14 ~16 days after sensitization and the sensitized rats were sacrificed 1h(AE), 6 ~8h(AL) and 1day(AD) after airway challenge, to examine the histologic changes of the lung. Airway responses were measured by body plethysmograph and recorded by enhanced pause(Penh) as an index of airway obstruction 6 ~8h after antigen challenges. Nonsensitized controls(10 rats) were also challenged with antigen and sacrificed 1 day later. Histopathologic examination of two trachea, large bronchi, small bronchi, and vessels was performed to evaluate the severity of inflammation and eosinophilic infiltration with H&E stain. RESULTS: In 17 of 20 rats(85%) in both groups, we observed airway responses. Among them, an early response(ER) in 15 rats(75%), an dual response in 5(25%), and an late response(LR) only in 2 rats(10%) displayed. There were no significant differences in the severity of inflammation among the trachea, large bronchi, small bronchi and vessels in all groups after antigen challenge(p>0.05) and between early and late responders. The significant eosinophil infiltration was observed in 5 rats(50%) of AL(p<0.05) compared with in AE and controls. Also, eosinophil infiltration was observed in higher trend in LR(57.1%) compared to ER(40%)(p>0.05). CONCLUSION: Sprague-Dawley rats sensitized with subcutaneous injection of OA showed a significant airway responses to antigen challenge. But antigen challenges caused a little eosinophil infiltration and no significant airway inflammation. Asthma model of Sprague-Dawley rats could be useful for antigen-induced airway responses, but this model has a limitation for the study of human asthma because of no significant pathologic change.

Multiple endocrine neoplasia (MEN) Ila is an inherited disease characterized by the development of medullary thyroid carcinoma, pheochromocytoma and hyperparathyroidism. It has been shown to be associated with germ-line mutatians in the RET proto-oncogene. Presymptomatic screening of medullary thyroid carcinoma in MEN IIa families enables the early diagnosis of this tumor with its significant morbidity, We describe a 19-year-old woman fmm a MEN IIa family who was founded by DNA analysis to be a gene carrier of MEN IIa and then was diagnosed, using a pentagastrin stimulation test, as having presymptomatie medullary thyroid carcinoma She underwent thyroidectomy and histologic examination confirmed medullary thyroid carcinoma. It is cancluded that direct genetic analysis for mutations in the RET proto-oncogene should be the diagnstlc test of choice for identifying family members at risk for MEN IIa and thyroidectomy on the basis of genetic analysis is a rational course of action.

Cardiac rhabdomyomas are the most common primary tumor in infancy and childhood and are frequently associated with tuberous sclerosis. Although spontaneous regression of cardiac rhabdomyoma has been reported , prognosis of this tumor associated with subaortic stenosis is still considered to be poor and surgery continues to be indicated. A 4-day-old female was admitted due to tachypnea and cyanosis. Single rhabdomyoma arising from the interventricular septum associated with severe subaortic stenosis was partially removed under cardiopulmonary bypass. Excised tumor size was 0.7 X 0.9 X 0.4 cm in dimension. The postoperative course was uneventful and the infant discharged on the 14th postoperative day.
