To investigate relationship between alpha1-acrenoceptors and nicardipine, an 1,4-dihydropyridine calcium antagonist, effects of nicardipine, on phenylephrinne(PE)-induced vasoconstriction in isolated arterial rings and pressor response of rabbits were observed. In normal physiological salt solution(NPSS), 35mM KCI produced persistent contractions of thoracic aorta and carotid artery and the contractions were dose-dependently inhoboted by cumulative admini-stration of nicardipine in the range of doses from 10(-10)M to 10(-4)M, IC50s of nicardipine in the thoracic aorta and carotid artery were 3.3x10(-7)M and 4.6x10(-7)M, respectively and there was no difference between both values. Constant contractions induced by 10(-5)M PE in both rings were inhibited by the same doses of nicardipine in a dose-dependent fashion. The IC50s were 2.8x10(-4)M in thoracic aorta and 2.9x10(-5)M in carotid artery respectively, and the former was about 10 times greater than the latter. In Ca2+ free PSS, KCI did not produce any contractionn. Though constant and reproducible in NPSS, PE-induced contraction was transient and not reproducible in Ca2+ free PSS. The contraction in both rings were weakened to about 70% of those in NPSS. Pretreatment with nicardipine in the range of doses from 10-8M to 10-5M hardly affected the PE-induced contraction and the largest dose 10(-4)M slightly inhibited the contraction. Intravenous injection of nicardipine 10 to 1000microg/kg decreased blood pressure and heart rate of rabbits in a dose-dependent manner. The % decrease of heart rate was much smaller in comparison with the %decrease of blood presseure. Pressor effect of 30microg/kg PE was dose-dependently inhibited after treatment with nicardipine 10 to 1000microg/kg and ID50 was 314microg/kg(6.1x10(-7)mole/kg). Above results suggest that nicardipine blocks extracellulr Ca2+ influx by membrane depolarization and in a part by alpha1-adrenceptors, then relaxes arterial smooth muscles in rabbits.

A case of histiocytosis X with the involvement of pituitary stalk in a 5 year old boy was described. He presented with diabetes insipidus and the endocrinological study showed growth hormone deficiency. On computerized tomography and magnetic resonance imaging, the pituitary stalk was abnormally thick. Overlooking of the skull lesion on plain X-ray film led to an erroneous diagnosis of germ cell tumor'. Gross total removal of the lesion and chemotherapy were performed. In the differential diagnosis of suprasellar masses, this disease entity should be included. The importance of histological diagnosis of the infundibular lesion in cases of central diabetes insipidus is also emphasized.

Since the identification of the C-group chromosome has been made possible by the introduction of banding technique, the features of the trisomy-8 syndrome have been defined. Most of them have been mosaics and have had similar clinical findings. A case of Trisomy-8 mosaicism confirmed by G-banding analysis by skin fibroblast and heart blood in a dead female fetus of 35 weeks of gestation is described.

Currently the number of pregnant women who have indications for, but do not receive, prenatal cytogenetic diagnosis is increasing. The purpose of this study was to review the prenatal cytogenetic services and to analyze the effect of genetic counseling on performance of the prenatal cytogenetic test. From January 1987 to July 1988, there were 2,796 deliveries at Severance Hospital, Yonsei Medical Center, of which 126 patients had indications for prenatal cytogenetic diagnosis. Chromosomal abnormalities were found in 5 patients (1, monosomy X; 1, trisomy 18; and 3, trisomy 21). Four patients were found in the group who had indications for prenatal cytogenetic diagnosis while only one was found in the group who did not (p less than 0.01). The most common indication for prenatal cytogenetic diagnosis was advanced maternal age (59%). The prenatal test rate was highest in patients whose indications were a previous child with chromosomal abnormality (100%) and parental translocation carrier (100%). Most (89%) of the patients were tested by amniocentesis between the 16th and 20th week of gestation. The two most common reasons for patients not receiving a prenatal cytogenetic diagnosis were late registration (41%) and absence of genetic counseling (34%).

Seventy cases of empyema treated on the pediatric Service of Kwangju Christian Hospital during 9 years 6 months from Jan. 1970 to Jun. 1979 were analyzed and summerized as follows : 1. Males outnumbered females 38 to 32. No seasonal difference in prevalence was notes. 2. About 60% of empyema(41 cases) were on the right side and 36% on the left side. In 3 cases both sides were affected. The most common concurrent disease was pneumonia, which was suspected as th etiology of empyema. 3. Common chief complaints were dyspnea(53%), fever(47%) and cough(43%). 4. Upon culture of pus, 21 cases among 63 cases(33%) showed no bacterial growth, indicating that had under gone antibacterical treatment before admission. 5. The most common causative organism was Staphylococcus aureus(41.2%) followed vy Pseudomonas(7.9%) Streptococcus(4.8%) E.Coli(4.8%) and Pneumococcus(4.8%). 6. Upon sensitivity test, no resistance was observed to Methicillin and Amikacin, but most of the causative agents were sensitive to Gentamicin, Cephalothin and Novobiocin, while they were least sensitive to Penicillin(17%) and colimycin(9%). 7. Average hospital days were 18, and two cases(2.9%) expired, both one year of age. Average duration of closed drainage was two weeks.

Apert syndrome is a rare disorder characterized by malformation of the skull, (usually oxyce-phaly or acrocephaly), in association with sys temic syndactyly It is due to congenital disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. The original description was presented by Troquart in 1886. Since then, more than 200cases have been reported in the world up to 1970. Recently we have seena patient with typical Apert Syndrome and report it here with a brief eviewr of the relevant literature.

Leukemia is a rare disease in the newborn infant. We have presented an autopsy case of congenital acute myelocytic leukemia in a female neonate and discussecd with review of literature. At birth, she was relatively in good health with 4.2 kg in body weight except a large cephalhematoma on left parietal scalp and multiple subcutaneous nodules with ecchymosis on entire body surface. Hemoglobin concentration was 12.0 gm/, Hct 34.6% and erythrocyte count was 2.24 millions. Of 212,400 leukocytes/mm2, 47% were myeloblast. Biopsy of skin nodules reveal leukemia cutis, which disappear dramatically with anticancer drug. The infant was expired 12 days after admission due to intracerebral hemorrhage and acute renal failure.
