Evlauation of pulmonary vascular changes and pre-and postoperative hemodynamic findings were performed in 25 patients who had ventricular septal defect associated with sevese pulmonary hypertension. Lung biopsy were done preoperatively in two patients and during operation in twenty three patients. Also the postoperative systemic and polmonary arterial pressure were obtained about 10-20 minutes after the cardiopulmonary bypass. The results were as follow: 1) There was no relationship between the severity of pulmonary vascular changes(Health-Edwards classification) and the patients age(X2=4.4427, P=0.2175). 2) There was a good correlation between preoperative ratio of pulmonary to systemic vascular resistance(Rp/Rs) and ratio of pre-and postoperative pulmonary to systemic arterial pressure(r=0.4846, P<0.05). 3) There was a significant correlation between the degree of medial wall thickness and preoperative Rp/Rs(r=0.6535, P<0.005). 4) There was no correlation between perioperative hemodynamic findings and medial wall thickness in the patients aged below 2 years.

Transforming growth factor beta(TGF-p), initially identified in vlatelet extracts by virtue of its ability to confer anchorage of independent growth and a necplastic phenotype on mesenchymal cells, has subsequently been identified as a potent inh bit or of proliferation in most cells of epithelial origin. The family of TGF-p peptides is currenly onsisted of four subtypes (TGF-pl, p2, p3, p4). Tkiey are initially translated very larged are urssors of approximately 390 amino acids and produced by a wide variety of cell type. iricluding normal cells and tumor cells. TGF-ps promote deposition of extracellular matrix compcineits, facilitate remodeling events during embryonic development, and suppress immune ce 1 fimetion during the inflammatory process. Several nutaneous diseases are characterized typxcessive and progressive fibrosis of the dermis anil subcutaneous tissues. Prominent amon these disorders are progressive systemic sclerosi(PSS) and generalized morphea(GM), is well as the recently described syndrome of diffuse fasciitis eosinophilia(DF), also known; Shulmans syndrome. The hallmark of the pathologic alteration in these disorders is the excessive deposition of collagen and other connenctive iissues. Macromoleculse in the aerriis and/or the subcutaneous and fascial strutures often accompanied by variable degress of hronic inflammatory cell infiltrates. Now we have examined the expression of TGF-b1 mRNA using of northern blot hybridization with specific sequenced cDNA probe in the normal curltured fibroblasts, placental tissues, and fibrosarcorna derived tumor cell line(HT1080). We found that the size of TGF-b mRNA of each specimen was 2.5kb and theres no alteration of its quality.

A 19-month old male patient developed mutiple, firm, plum-colored, finger tip to chestnut sized nodules on the left cheek, right preauricular area, both elbow joints, and right wrist. On physical examination, a right cervical lymph node was palpable. Histology from one of the nodules revealed a diffuse infiltration of atypical, hyperchromatic, polymorphous lymphocytes in the dermis and subrutaneous fat. Bone marow aspiration, chest X-ray, ultrasonogram, and computerized tomogram were performed revealing bone marrow and lymph node involvement. The patient was treated with a POG @8617 schedule. Skin lesions markedly improved after one cycle regimen. We present a case of diffuse, ponrly differentiated, malignant lymphocytic lymphoma in the early childhood.
