Thirty cases of peripheral nerve injury were selected and analysed by means of electromyographic studies at Severance Hospital, Yonsei University, from January 1972 to August 1972. 1. The sex ratio was 17:13 (male: female). The peak incidence occurred in the twenty to thirty year age group. Involved side: right side 18 cases: left side 12 cases. 2. Nerve involved: peroneal nerve (15 cases), tibial nerve (2 cases), median nerve (7 cases), ulnar nerve (4 cases) and radial nerve (2 case). 3. Mode of nerve injuries 1) Peroneal nerve: Nerve compression, variable (10 cases) Tibia & fibular fracture complication (4 cases) Stab wound, fibular neck region (1 case) 2) Tibial nerve: Injection neuritis, buttock (2 cases) 3) Median nerve: Cut glass laceration, wrist region (3 cases) Carpal tunnel syndrome (3 cases) Undetermined mode (1 case) 4) Ulnar nerve: Cut glass laceration, wrst region (2 cases) Forearm bones fracture complication (1 case) Supracondylar fracture (cubitus valgus) (1 case) 5) Radial nerve: Cut glass laceration, wrist region (1 case) Crushing injury, elbow region (1 case) 4. Among the 15 cases of peroneal nerve injury, there were 10 cases of partial denervation and 5 cases of complete denervation. 5. The mode of injury in 10 cases of partial denervation was nerve compression from the following causes: lithotomy posture during forceps delivery (1 case), external rotation of legs during recovery state after surgery (3 cases), abnormal posture during coma state after CO intoxication (2 cases), tight long leg cast (3 cases), and direct trauma while descending stairs (1 case). 6. In all 10 cases of partial denervation of the peroneal nerve, decreased motor nerve conduction velocities, diminished amplitude and prolonged latencies were observed. 7. In partial denervation of the peroneal nerve, the earliest that reinnervation was observed was within 3 weeks in 3 out of 10 cases. 8. Spontaneous fibrillation was observed 3weeks after injury in all cases except one in which it was observed only 7 days after peroneal nerve injury. 9, The earliest appearance of positive sharp waves among all peroneal nerve injuries was observed 2 weeks after injury. 10. The initial appearance of nascent potentials (polyphasic potentials) in peroneal nerve injuries was observed 3 weeks after injury (1 case), 5 weeks after injury (1 case), and 5 months after injury (1 case). They are all partial denervation cases due to nerve compression. 11. Ten cases of partial denervation of the peroneal nerve were treated with electrical stimulation and drop foot board with good recovery. Five cases of complete denervation of the peroneal nerve were treated with neurorrhaphy (1 case) and short leg bracing (4 cases). 12. The initial appearance, of polyphasic potentials was observed 5 months after injury in one case out of 3 cases of median nerve injury. 13. Three cases of median nerve injury were classified as carpal tunnel syndrome and occurred in women only. Observations included absence of sensory nerve action potentials below the lesion, delayed distal latency at wrist and normal motor nerve conduction velocity. They were treated by division of the deep transverse carpal ligament with good result. 14. The initial appearance of nascent potentials was observed 7 months after injury in one case among 3 cases of ulnar nerve injury. 15. In two cases each of radial and tibial nerve injury, no reinnervation pattern was observed until the six month follow-up study after injury. At that time no muscle contraction could be seen or palpated clinically. 16. We observed normal motor unit potentials in the muscles in the follow-up studies even though muscle contraction could not be seen or palpated clinically. 17. Electromyographic examination at selected intervals made accurate diagnosis and prognosis possible and aided in evaluating the course of nerve regeneration, which permictted the choice of appropriate treatment.

We present an autopsy case of signet ring cell carcinoma of urinary bladder which underwent widespread metastsis through nearly entire organ. The patient, 45-year old male, suffered from hematuria, dysuria and flank pain for 6 months. Under the diagnosis of the signet ring cell carcinoma by the cystoscopic biopsy, radical cystectomy and ileocutaneous ureteral division were performed. But he died after 11-months after the diagnosis. The autopsy confirmed the widespread metastasis at the lung, kidney, adrenal gland, parathyroid gland, heart, stomach, ileum, spine, rib and meninges. The preveously resected urinary bladder discolosed the well defined fungating mass at the dome and anterio-lateral portion without apparent evidence of the remnant of the urachus. Histologically, the signet ring cells were predominent and focally mucinous pool floating the signet ring cells was noted. We could find several foci of the well differentiated adenocarcinoma and poorly differentiated adenocarcinomas. The above findings may reflect that the origin of carcinoma may be from the multipotential transitional cell epithelium.

In this study, the feasibility of identification and genotypic differentiation of enteroviruses was investigated by using nested reverse transcription-polymerase chain reaction (nested RT-PCR), single-stranded conformation polymorphism (SSCP), and restriction fragment length polymorphism (RFLP) techniques. Two hundred seventy-four clinical samples were assayed by both nested RT-PCR and tube culture method using MRC-5 and MK cells; 58 (86.6%) out of 67 enterovirus culture-positive samples contained enteroviral RNA. In addition, 114 (55.1%) of 207 samples from patients with suspected enteroviral CNS disease with negative viral cultures were positive by the nested RT-PCR. The nested RT-PCR products were genotyped by the SSCP method and the results were compared with serotypes. We could differentiate 6 subtypes, 3 of which are similar to coxsackievirus B3, B5, echovirus 11, plus 3 other subtypes. RFLP cleaved with Sty I, Bgl I, and Xmn I yielded characteristic patterns for each laboratory strains. This study demonstrates the usefulness of the RT-PCR for the rapid diagnosis of enterovirus infection and the potentials of the SSCP method for differentiation of enterovirus strains.

The purpose of this study was to investigate the nutrient intakes, nutritional knowledge, food habits, and lifestyle behaviors of moderately or severely obese children living in the Kyonggi-do area. The subjects in this study were 37 obese children with an obesity index higher than 130% in the forth to sixth grades of elementary school. Anthropometric measurements, 24-hour recall of dietary intakes, and a survey on nutritional knowledge, food habits, and lifestyles behavior were conducted in the 37 obese children (25 boys and 12 girls). The average age, body weight, BMI, and Rohrer Index were 12.4 years, 68.6 kg, 29.6 kg/m2, and 194.9 in boys and 12.7 years, 65.7 kg, 29.8 kg/m2, and 201.8 in girls, respectively. The percentage of correct answers on nutritional knowledge and nutritional attitude score/max score were 85.8% and 23.0/50 in boys and 87.0% and 17.5/50 in girls, respectively. Except for calcium (85.3%) in girls and calcium (62.7%) and folic acid (83.3%) in boys, the average daily nutrient intakes percentages of nutrients were greater than the DRIs values (107.9~327.3% in boys and 103.0~416.0% in girls). This study showed the existence of some problems associated with obesity, such as higher frequency of skipping breakfast, irregular meal times, unbalanced diet, lack of intake of some nutrients, low nutritional attitude, lack of physical activity, and time management in obese children. These results suggest that a systematic education program including nutritional education on balanced diet, good eating habits and behaviors, and importance of eating breakfast and meal regularity must be emphasized to improve nutrient intakes and food habits in obese children. Obese children also require a more concentrated program that includes physical activity, weight reduction, and weight maintenance strategies to improve their life habits.

BACKGROUND: The purpose of this study is to evaluate what kind of crystalloid solution could function as the best buffer and correct the metabolic acidosis most effectively in rabbits with hemorrhagic shock. METHODS: Twenty eight rabbits were bled until mean arterial pressure(MAP) became 70% of control. Thirty minutes after hemorrhagic shock fluid resuscitation was started with either plasmalyte or Hartmann's solution or 0.9% normal saline until MAP returned to 90% of the control. Hemodynamic and blood gas study, plasma lactate and electrolyte concentration were measured before, during, and 30 minutes after recovery from shock. RESULTS: The amount of shed blood to reduce MAP to 70% of control ranged 76~87 ml. And the volume for fluid resuscitation was 274~324 ml. There was no statistically significant difference among the three groups. The pH decreased during shock in all group and still decreased after resuscitation in Hartmann's solution and normal saline. But it increased significantly after resuscitation in plasmalyte. Lactate was increased in all group during shock and decreased by 22 and 23 mg/dl after resuscitation in plasmalyte and normal saline. But it still increased by 40 mg/dl in Hartmann's solution. Serum potassium level decreased significantly after resuscitation with normal saline. Serum calcium level decreased significantly after resuscitation with plasmalyte and normal saline. CONCLUSION: With the above results the plasmalyte which has pH closer to that of normal blood might be able to avoid the metabolic acidosis and maintain acid-base equilibrium effectively after fluid resuscitation in acute hemorrhagic shock.

BACKGROUND: Baroreceptor reflex responds to the decrease in blood pressure caused by drug, dehydration, or severe bleeding. Vagal reflex caused by direct pressure on vagus nerve, the traction, or lung inflation develops bradycardia and severe arrhythmia. Lung inflation elicits a vasodepressor reflex, resulting in stimulation of the vagus nerve which causes a decrease in sympathetic outflow. METHODS: 75 patients who had elective surgery were divided into 3 groups according to the age, such as group I: < or =15 years of age, group II: 16-64 years of age, group III: > or = 65 years of age. Lung inflation test has been performed at 20 cmH2O for 20 seconds. Baroreceptor was stimulated by lowering blood pressure with intravenous infusions of nitroglycerin. Baroreceptor sensitivity was assessed by measuring the decrease in blood pressure. Vagal reflex sensitivity was calculated by the subtraction of G2 (baroreceptor reflex sensitivity after introglycerin infusion) from G1 (heart rate response to lung inflation). RESULTS: Baroreceptor reflex induced by hypotension and vagal reflex originated from lung influe-nced the heart rate inversely when lung inflated. Baroreceptor reflex sensitivity was highest in younger patients and lowest in older patients when nitroglycerin infused. Vagal reflex sensitivity was highest in older patients and lowest in younger patients. CONCLUSIONS: Baroreceptor reflex was most sensitive in younger patients, but vagal reflex was moresensitive in older patients.

We report a case of Hunter' s syndrome with characteristic nodules on the upper back. The patient was a 7-year-old Korean boy who presented with ivory-colored papules and nodules on both sides of the scapula, pectoral regions and lateral aspects of the upper arms. These lesione are regarded as pathognomonic cutaneous markers for Hunter s syndrome. He also presented with truncal hypertrichosis, retarded growth, short neck, round face, claw like contractures of hands, multiple joint contractures, and a clear cornea. Severely elevated glycosaminoglycan levels were present in the patient s urine samples. The patient s 5-year-old brother had similar clinical features.
