The development of the cardiac ganglion was studied by electron microscopy in human fetuses ranging from 30mm to 270mm crown rump length. At 40mm fetus, the cardiac ganglia were observed in the adventitia of both the aorta and pulmonary artery, superior aspect of the left and right atrium, and interatrial septum. The cardiac ganglia were comprised of clusters of undifferentiated cells, neuroblasts, and unmyelinated nerve fibers. The ganglia were small and uncapsulated until 70mm fetus. At 70mm fetus, the cardic ganglia consisted of neuroblasts, satellite cells, and unmyelinated nerve fibers. Each ganglion was ensheathed in a connective tissue capsule. The cytoplasm of neuroblast contained Nissl bodies, mitochondria, coated vesicles, extensive Golgicomplex, and rough endoplasmic reticulum. Synaptic contacts between the cholinergic preganglionic axon and dendrites of postganglionic neuron were first observed. At 100mm fetus, the cardiac ganglia consisted of small clusters of ganglion cells and dendrites, together with supporting elements and blood vessels. During next prenatal stage from 170mm fetus, the ganglion cells were large and each contained a large nucleus with one or more nucleoli. The cytoplasm of ganglion cells contained much rough endoplasmic reticulum and extensive Golgi complex. Cholinergic preganglionic axons were numerous and interposed between the satellite cells. Adrenergic axons were rarely observed. A great number of synaptic junctions between the cholinergic preganglionic axon terminals and the dendrites of postganglinic neuron were found, and a few axosomatic synapses were also observed. Adrenergic nerve terminals did not seem to be involved in the synaptic transmission. The cardiac ganglion cells of the human fetal heart were innervated only by cholinergic nerve.

A statistical study of soldiers who visited the outpatient ciepartment of the Capital Armed Forces General Fiospital from 1987 to 1989 was performed. The results were as follows : 1. The total number of outpatients was 9969 with peak clinic visits in June(11.2%) and the lowest number of clinic visits in February(6.4% ). 2. The most frequent age was 22 years(20.7% ). Soldiers between 19 and 24 years old comprised 68.1% of total patients. 3. By rank 69.3% of the outpatients were private', 16.0% sergeant and 14,4% officers. 4. The most common dermatoses were dermatophytosis, contact dermatitis, scabies, acne, seborrheic dermatosis, urticaria, alopecia, condyloma acuminatum, verruca, folliculitis, psoriasis, insect bite reactions, pityriasis rosea, herpes zoster and corns. 5. Frequent diseases, which occured during summer season, included dermatophytosis, contact dermatitis and inser,t bites. The incidence of scabies, pityriasis prsea was increased during winter and that of psoriasis was increased during spring.

A case of hypertrophic lichen planus was reported and the literature reviewed. A 69-year-old widowed woman displayed generaIized discrete, multiple, round, various sized, flat-topped, hypertrophied papules and nodules on the abdomen, trunk and four extrimies for 42 years. An electron microscopic finding revealed widespread breakdown and thickening of the basal lamina at the dermo-epidermal junction and a degenerating change of the desmosomes. No particular intran uclear particles or bodies were discovered. We suggest that emotional factors and autoimmune mechanism might be the cause of the eruption in this case.

A retrospective study was designed to determine the diagnostic contribution of oblique view in 740 consecutive lumbar spine examinations done in adults. In 12 cases (1.62%) there was a change in the radiographic interpretation when the oblique views were used for diagnosis. Considering the significant gonadal radiation, additional cost, and limited diagnostic value, the authors feel that the oblique view should not be a routine part of the initial lumbar spine examination in adults.

Pulmonary edema is a rare adverse reaction to the iodinated contrast medium. Complaining of huge abdominal mass, a 52 years-old female was admitted to the Hangang Sungsim Hospital. On physical examination, the patient appeared to be healthy. She had stable vital Signs, i.e. BP: 120/80 mmHg, pulse rate: 80/min. etc. An adult head sized mass was palpated in the left mid and lower abdomen. Otherwise nonspecific. On laboratory studies, the positive findings were 8-10 WBC/HPF in urine, 25.6 mg/dl for BUN and PVC in EKG. It was negative for urine protein, serum creatinine and liver function test. We injected 100ml and 30 ml for Urografin 60 through the abdominal aortadividing 3 times and major branches of the abdominal aorta, respectively. Immediately after completing angiography, interstitial pulmonary edema was found, showing blurring of the vascular margins, perivascular haziness and thickening of the interiobular septal lines in the both lower lung fields. The blood pressure was dropped to 80/60 mmHg, but pulse rate was normal. She did not complian of dyspnea, and cyanosis was not developed. The urine volume was normally maintained. She was treated for pulmonary edema, which was completely absorbed after 20 hours. And the blood pressure was also normalized. We has experienced a case of pulmonary edema developed after intraarterial injection of the iodinated contrast medium without underlying cardiac, renal and hepatic problems, and reviewed the literatures on mechanisms of pulmonary edema caused by intravascular injection of the iodinated contrast materials.

1. The plain abdominal films of 246 cases of intussusception preceding hydrostatic barium enema were analysedin order to reassess the diagnostic reliability of the abdominal plain film examination. Then, these were comparedwith 42 cases in which the diagnosis had been rejected by means of barium enema. 2. It was found that diagnosis ofthe intussusception was possible in 80% of 246 cases on the basis of plain film findings alone. 3. The most commonand reliable findings of intussusception in plain film diagnosis are those of sparse faecoloid bowel content andsparse amount of intestinal gas. 4. The loops of distended small bowel in cecal or ascending colon area andintraabdominal soft tissue mass are considered to be relatively reliable findings. 5. In 42 cases in which thediagnosis had been rejected by means of barium enema, intussusception was excluded in 745 of the cases on thebasis of plain film findings alone.

Although many invasive studies in the biliary tract disase are replaced by noninvasive techniques such asultrasonography and CT, PTC does still play an important role indiagnosis of obstructive jaundice. Authors hadperformed 42 patients of PTC with Chiba needle at the department of radiology, Han Gang Sacred Heart Hospital for4 years from Jan. 1978 to April 1982. And we reviewed literatures. The results were as follows; 1. Forty twopatients of PTC were 22 males and 20 females. The success rate was 90.5%(38/42). The failed 4 cases of PTC werenonobstructive hepatobiliary diseases. 2. The PTC diagnosis of 38 cases were biliary stone (21 cases),cholangiocarcinoma(7 cases), pancreatic carcinoma (2 cases), hepatoma (2 cases), ascariasis(2 cases), andclonorchiasis(1 case), and the remainders were normal. 3. We made 2 cases of misdiagnosis on the basis of PTCfindings. They were one case of distal CBD stone with severe cholangitis diagnosed as ampullary carcioma andanother case of proximal CBD stone with cholangitis diagnosed as pancreas carcinoma. 4. We experienced 2 cases ofcomplication such as sepsis and severe hypotension, but they were recovered.

An ABO discrepancy was observed in a 19-year-old man clinically diagnosed as congenital hypogammaglobulinemia. The patient's red cell was typed as group O, and his serum had no ABO isoagglutinins. Absence of A antigen and B antigen on patient's RBC was confirmed by adsorption- elution test and saliva test. A-transferase and B-transferase activities were not demonstrated in patient's serum. Patient's serum protein electrophoresis revealed hypogammaglobulinemia pattern, and immunoglobulin levels were markedly decreased. Complete absence of B lymphocytes was observed on patient's lymphocyte subset profile. Patient's father and mother were typed as blood group O and no abnormalities were recognized in their serum protein electrophoresis patterns and immunoglobulin concentration.
