Sick neonates often require periodic small volume transfusion (10mg/kg) to replace blood draw for laboratory monitoring during their hospital stay. The effect of packed red cel transfudion on the hematocrit, potassium, ionized calcium, acid base status, glucose and indirect bilirubin was investigated in 25 transfusions. Analysis of transfused blood by the age of the red cells, older red cells (more than 5 days old, 13+/-7 days) showed increased potassium (27.2+/-14.1mEq/L vs 11.3+/-4.9mEq/L), decreased bicarbonate (14.4+/-2.6mEq/L) and glucose (130+/-28mg/dl vs 203+/-93mg/dl) compared with newer red cells (less than 5 days)(p<0.05). No significant changes occured in hematocrit and pH. Inspite of these results, the transfusion of the older red cells did not affect the older red cells did not affect the serum potassium, ionized calcium, pH, bicarbonate, glucose and indirect bilirubin level in neonates. The hematocrit of infants increated significantly after transfusion from 29.6%+/-4.3% to 38.3%+/-6.1%(mean+/-SD)(P<0.05). Transfusion of older red cells seemed to be as equally effective as newer ones. The valus of hematocrit obtained immediately after transfusion does not show any differences compared to those obtained 30 min, 1, 2, 4, 6 and 24 hours after transfusion. The result in the study indicate that there was no adverse effect after transfusion with packed red cell more than 5 days old and no significant difference in hematocrit observed between 0 to 24 hours following transfusion. Therfore old red cell more than 5 days can be used safely for sick neonatal transfusion and the stored donor blood can be optimzed for repeated blood transfusion.

This study was performed with the purpose of histochemical comparison of CEA and EMA localization between adenoma and well-differentiated adenocarcinoma of the stomach. The specimen was 12 lesions of adenoma and 15 foci of well-differentiated adenocarcinoma of the stomach. The markers in neoplastic tissue and neighbouring mucosa of the tumors were examined in paraffin sections using peroxidase-antiperoxidase method. The data obtained were evaluated statistically. The results were summarized as follows: 1) In 12 lesions of stomach adenoma, the positive reaction to CEA was seen in 3 lesions (20.0%), and to EMA in 10 lesions (83.3%). The positive rate of CEA in adenoma was lower than that of the neighbouring normal mucosa, but the positive rate of EMA was similar between the two. 2) In 15 foci of well-differentiated adenocarcinoma of the stomach, the positive reaction to CEA was seen in 13 foci (86.7%), and to EMA in 12 foci (80.0%). The positive rate of CEA in well-differentiated adenocarcinoma was higher than that of the neighbouring normal mucosa, while the positive rate of EMA was similar to each other. 3) Immunoreactivity to CEA in adenocarcinoma showed good positive correlation with the development of cuticular border of the neoplastic glands, while reactivity to EMA in adenocarcinoma was not related with the development of cuticular border. 4) The positive rate and intensity of CEA reaction in adenocarcinoma were higher than those in adenoma, but the positive rate and reactiveity of EMA were similar to those of adenoma. 5) The positive rate of CEA or EMA in the neighbouring mucosa of adenoma was not different compared with those in the neighbouring mucosa of adenocarcinoma. With the above results, it is concluded that adenoma and adenocarcinoma of the stomach may be different each other, biologically, and further more, it is presumable that adenoma may not be a premalignant lesions. It is considered that examination of CEA immunoreactivity may be helpful in differentiated of adenoma from well-differentiated adenocarcinoma, in most cases.

A case of mucous gland adenoma arising from the main bronchus of the middle lobe of the right lung is reported, with review of related literatures. The patient, a 12 year-old Korean male, was admitted to Pusan National University Hospital with complaints of progressive coughing and dyspnea. Roentgenographic studies revealed a well defined mass involving the right middle lobe of the lung. With the impression of benign tumor, right middle lobectomy was performed. The gross specimen revealed a polypoid mass involving the main bronchus, measuring 4.5x 3.7 x 2.5cm. The cut surface of the mass revealed yellow-gray myxoid tissue. Histologically, the mass consisted of glandular structures filled with mucus, which proved to be acid one on histochemical study. The glandular lining was made up of a single layer of berign mucous cells, many of them being flattened.

In 56 breast cancer tissues (infiltrating ductal carcinoma) with a clinical follow-up period of more than 5 years, positivity of estrogen receptor(ER) by enzyme immunoassay and expressions of bcl-2 and p53 oncoproteins by immunohistochemistry were evaluated. The purposes of this study were to determine prevalence of bcl-2 and p53 in breast cancer, the interrelationship between expression of the proteins and estrogen receptor, correlation between histologic grade and the expression of the tumor-related oncogenes, and to explore the biologic bahavior of breast cancer (lymph node metastasis, recurrence rate, and survival) via expression of bcl-2 and p53. Twelve of 56 (21.4%) carcinomas were bcl-2 positive, and seventeen (30.4%) were p53- positive. Eleven of 12 bcl-2 positive tumors (91.7%) were ER-positive, and bcl-2 expression was significantly associated with ER-positivity(P=0.043). Seven of 36 ER-positive tumors (12.5%) were p53 positive, and p53 expression was inversely associated with ER-positivity(P=0.006) significantly. The bcl-2 protein expression showed a significant relationship to low histologic grade of tumor (P=0.0002), and an almost significant relationship to lower recurrence rate (P=0.09). The p53 protein expression showed a significant relationship to high histologic grade of tumor (P=0.002) and an almost significant relationship to lymph node metastasis (P=0.09). Also an almost inverse relationship between bcl-2 and p53 was demonstrated (P=0.057). The bcl-2 expression had a tendency to be associated with longer patient survival(P= 0.09), but p53 immunoreaction was found not to be associated with shorter patient survival(P=0.16). These results provide further evidence that higher incidence of bcl-2 expression is correlated with higher incidence of ER and lower grade of tumor, while p53 expression is correlated with lower incidence of ER and higher grade of tumor. In conclusion, although the biologic function of bcl-2 protein is not yet well understood in breast cancer, our results suggest that bcl-2 and p53 oncoproteins might play significant roles in estrogen receptor and development of breast cancer. But their prognostic significance could not be determined; our results are 'not significant' but 'almost significant'. Thus, contribution of bcl-2 and p53 immunohistochemical phenotyping of breast cancer with ER to the clinical management need verification in larger series.

Dysplasia epiphysealis captitis femoris is a rare syndrome which after the hip joing in childhood. Pedersen(1960) was the first to differentiate dysplasia epiphysealis capitis femoris(DECF) from Perthes' disease. Scattered reports of this entity have appeared, and in 1964 Meyer defined the syndrome through explanation of its clinical and radiological characteristics. There is a clinical significance that DECF is clinical-radiologic syndrome which resemble Perthes' disease but has important differences, especially in its treatment and prognosis, We experienced two cases of DECF which are misdiagnosed as Perthes' disease. Therefore, pediatricians should keep in mind the possibility of the DECR among the Perthes' disease of younger children.
