Korean Journal of Pathology 2000;34(6):413-418
We induced apoptosis in normal rats by intramuscular injection of 5-fluorouracil (5-FU) and immunohistochemically evaluated the thymus for the TdT-mediated dUTP biotin nick end labelling on the 1st, 3rd, 6th, 9th, 15th and 21st days following the bolus intramuscular injection. The injections of 5-FU induced a greater extent of apoptosis in the thymus. In the thymus, a mild increase in apoptosis was observed 24 hours after injection. The greatest number of apoptotic cells were seen at 72 hours. The size of the thymus decreased and the cortex thinned with hypocellularity. The injection of 5-FU caused massive cell loss in the thymus. Most apoptotic cells were scattered in the cortex and lower levels of apoptosis were also observed in the medulla. After 72 hours, the level of apoptosis returned to the control level. Considering the above results, we think that 5-FU induced toxicity may be related to 5-FU induced apoptosis in normal tissue, especially the thymus.

The study was undertaken to determine the most adequate tidal volume when used volume preset ventilator during anesthesia. The thirty patients were received controlled mechanical ventilation with constant inspiratory pressure of 10 cmH2O and respiratory frequency of 12/minute. The results were as follows: 1) The PH was 7.39±0.01 and it is within normal limit. 2) The PaCO2 was 34.0±0.6 mmHg and it is a slightly hyperventilatory state. 3) The PaO2 was 228.0±8.2 mmHg. 4) The Buffer base was 20.7±0.3 mEq/L and it is a slightly buffer base deficient state. From the above results. We concluded that if patients were fully relaxed during general anesthesia, it is desirable to maintain the inspiratory pressure of anesthetic mechanical ventilator to 10 cmH2O for adequate alveolar ventilation.

Williams syndrome is a progressive and multisystemic disorder. We experienced one case of Willams syndrome which was characterized by elfin facies, mental retardation, diffuse aortic hypoplasia, mitral regurgitation and chronic nonparoxysmal sinus tachycardia. The tachycardia has been managing with beta-blocker successfully. We presented a case of unusual form of Williams syndrome with a reivew of literatures.

6.A Case of Type I Glycogen Storage Disease with Decreased Growth Hormone Secretion.

Glycogen storage diseases(GSD) are inherited disorders affecting glycogen metabolism and type I GSD is due to the absence or deficiency of glucose-6-phosphatase(G6Pase) enzyme in the liver, kidney, and intestinal mucosa. The defect leads to inadequate hepatic conversion of G6P to glucose and thus make affected individuals susceptible to fasting hypoglycemia, and the accumulation of glycogen occurs in the liver and other organs. Type Ia is the most common form of GSD and clinically growth retardation may manifest of GSD itself rather than growth hormone deficiency(GHD), but we experienced a case of type I GSD with GHD in a 14-year-o1d male. The height was 125 cm, compatible with 50 th percentile of height of 8 years of age. He has doll-like face with fat cheek, relatively thin extremities, and metabolic acidosis, hyperuricemia, hypoglycemia, hyperlipidemia. GH stimulation test with clonidine and L-dopa revealed that the patient had decreased GH secretion. After laboratory work up including liver biopsy, he was diagnosed as type I GSD. Hypoglycemia was managed with frequent feeding with high starch diet(uncooked cornstarch). Metabolic acidosis and hyperuricemia were treated with sodium bicarbonate, allopurinol and probenecid. The patient is being followed at out-patient clinic with clinical improvement after of diet therapy and GH administration.

Chronic hepatitis associated with the idiopathic hypereosinophilic syndrome has been very rarely reported worldwide. Recently, we experienced a case of chronic hepatitis with piecemeal necrosis as the clinical feature of the idiopathic hypereosinophilic syndrome. The patient was a 49-year-old woman who complained of a mild fever, nausea, vomiting, and pain in the right upper quadrant. The eosinophil count of peripheral blood increased up to 14,020/microliter (64% of WBC). Liver biopsy specimen showed severe porto-periportal inflammation with marked eosinophilic infiltration and ballooning degeneration of hepatocytes. Corticosteroid therapy significantly normalized the eosinophil count of peripheral blood.

Benign hemangioma of the mediastinum is rare. This slowly growing tumor is described as well circumscribed, cystic, hemorrhagic tumor. Histologically it can be differentiated into capillary or cavernous form. We present a case of mediastinal hemangioma. A 20-year-old-man was presented with a slowly growing posterior mediastinal mass of 6 years duration, 8x6 cm in size. The mass was relatively well defined but focally invasive. Microscopically, it was differentiated into vessels of capillary, cavernous, and venous patterns. A solid cellular proliferation with inconspicuous capillary lumens was focally seen. The stroma between variable-sized vessels showed marked myxoid change associated with some smooth muscle bundles and adipose tissue. Ultrastructurally, areas of solid cellular proliferation showed formation of lumens. These lumens were lined by active endothelial cells showing plasmalemmal vesicles and Weibel-Palade bodies on the abluminal surface.

We reviewed 7 cases of congenital mesoblastic nephroma (4 cases of classical mesoblastic nephroma (CMN) and 3 cases of atypical mesoblastic nephroma (AMN)) using immuno-histochemical and flow cytometric study. Results are as follows. 1) The mean tumor size was 5 (3 to 7cm)cm in CMN and 9 (7 to 10cm)cm in AMN. The AMN revealed hemorrhage and necrosis in two Of three cases. A case of AMN showed cystic change without hemorrhage and necrosis. Mitotic count ranged in 0~4/10HPF in CMN and 20-35/10HPF in AMN. 2) Immunohistochemistry for vimentin was all positive. Actin, desmin were weakly positive in CMN, but negative in AMN. The findings were consistent with myofibroblastic differentiation in CMN and AMN was considered to be the less differentiated form of CMN. 3) Flow cytometiic analysis showed diploidy in two of two CMNs and two of three AMNs. Only one AMN showed aneuploidy with DNA index of 1.41. %SG2M were 8.1 and 15.9 (mean 12.0) in CMN and 16.9, 32.9 and 19.3 (mean 22.9) in AMN, respectively. We concluded that AMN should be distinguished from CMN, clinicopathologically.
