Abstract PDF

Delayed emergence of speech or language are frequent causes for concern about development during early childhood. Delay in evaluation and proper management until school entry in more likely to result in frustration, anxiety and school failure. Many language disturbances and their attendant behavior disorders respond to intensive language therapy. Authors analyzed the medical records of 52 children with delayed language development evaluated during 30 months from January 1986 through June 1988. The results were as follows: 1. The majority of cases were evaluated at the age of 2-2.9 year old (16 cases, 30.8%) and 3-3.9 year old (11 cases, 21.2%) 2. Male to female ratio was 3:1 3. The most common cause was mental retardation (53.8%), followed by developmental language disorder (23.1%) and autism (13.5%) 4. The most common associated condition was dysarticulation (17.3%), followed by strabismus (9.6%) and seizures (7.7%) 5. Special education was recommended in cases of 23 (44.2%), speech therapy in 12 cases (23.1%) and consultation to child psychiatry in 7 cases (13.5%) Making diagnosis of underlying disorders in not simple because assessment of intelligence in young children in difficult and only a few tests are standardized. More detailed study on children with delayed language development and development of psychometric tests for handicapped children are necessary, especially in Korea.

Abstract PDF: Recently, many authors have reported about the relationship of the volumes of hemorrhage in the brain parenchyma, hemorrhagic sites, optimal operation time, and the effects of mannitol and steroid on control of ICP to clinical manifestations. Many attempts to measure ICP in hydrocephalus, brain tumor, and head injury have been reported. But the measurements of intracranial pressure in spontaneous intracerebral hemorrhage are rare. Intracranial pressure was monitored prospectively in 30 patients who had stereotaxic surgery for spontaneous intracerebral hemorrhage. The results are as follows. 1. Intracranial pressure was increased in high PaCO₂. 2. There were no correlation in ICP, rebleeding and ADL ad discharge (P>0.05). 3. ICP was the most high level in 72 hours after operation. 4. There was 63.2% decrease in ICP after irrigation with 6000 IU urokinase in the site of hemorrhage. 5. There was no correlation between the numbers of natural drainage and ADL at discharge (P>0.05). 6. The higher the initial GCS, the higher the postoperative GCS.

Abstract PDF: There had been no reports of trichophyton tonsurans infection in Korea yet. We have much chances to import the organism through international travels and exchanges. But we, Korean, have no experiences to observe T. tonsurans. Author tried mycological studies with T. tonsurans insolated in New Orleans, USA. The results are as follows: Gross findings of T. tonsurans showed that fine granular surface with light yellow hue or white color and grooving in the central area on the front side and mahogany brown color on the reverse side. On the urease test, various reddish discoloration was noted. Microscopic findings showed that septated hyphae, macroconidia, chlamydoconidia and microconidia. Macroconidia were 305 septated, smooth-surfaced, and were found more frequently in the whitish colony. Microconidia were characteristic in their arrangement and shape; round or oval shaped microconidia laterally to hyphae, some were match-head like terminal swelling. Hair perforation test showed positive results in 16 strains among 19 tested strains. All these findings are similar to T. rubrum and T. menatgrophytes, the most frequent isolates of dermatophytes in Korea, and we have to pay an attention to differentiate carefully.

Abstract PDF: The toxic effect of azalea extract, especially on cardiovascular system, in relatively unclear. The purpose of this study is to study the possible underlying mechanism and effect of toxic ingredient of azalea on cardiovascular system. The 71 healthy rabbits were divided into 10 groups: In group as preliminary study; 4 cc of normal saline was administered intravenously (N); 0.7 gm/kg and 1.0 gm/kg of azalea extract was administered respectively in the same route, volume (A1, A2); atropine was administered intravenously (A); after pretreatment with atropine (0.04 mg/kg) to block parasympathetic system, azalea extract was injected like the above groups (AA1, AA2); normal saline, 0.7 gm/kg and 1.0 gm/kg of azalea extract were administered respectively with 0.2 cc (1:1000) epinephrine (E0, E1, E2). We measured the following indices at I minute interval during first 10 minutes and then 10 minute interval during next 30 minutes: RR interval, QTc interval, maximal systolic and diastolic pressure drop with occurring time and presence of significant arrhythmia. The results were as follows: 1. The changes of RR interval, QTc interval were significantly increased in groups by Azalea extract. The blood pressure change was significantly decreased in groups by Azalea extract. There were no significant differences according to dosage of Azalea extract. 2. The changes of RR interval, blood pressure were significant differences between administration of atropine and Azalea extract after pretreatment with atropine, but not in the change of QTc interval. 3. There were no significant differences in the change of RR interval, ATc interval, blood pressure drop according to pretreatment with atropine. 4. The interaction between epinephrine and Azalea extract was not noted by the effect of epinephrine itself. 5. The ST change by 0.7 gm/kg, 1.0 gm/kg of Azalea extract was revealed in 1 case (14.0%), 7 case (100%), respectively. 6. Most of all cases with arrhythmia, ventricular tachycardia, ventricular fibrillation, were noted in the group by epinephrine, except on case by Azalea extract (1.0 gm/kg). It was idioventricular rhythm. In conclusion, azalea extract has negative inotropic and chronotropic effect with arrhythmogenic potential possibly through direct myocardial ischemia or injury but we can't be absolutely exclusive of actions of autonomic nervous system, especially parasympathetic nervous system.

Abstract PDF: Nucleolar organizer regions (NOR) are loops of ribosomal DNA (rDNA) which are transcribed by RNA polymerase I. They produce ultimately ribosome and protein. Thus they are believed to reflect nuclear activity. We applied silver colloid staining technique to human glioma to examine relationship between the mean number of Ag-NOR and histopathological grading. The mean number of Ag-NOR (±S. E of the mean) were 1.17±0.07 in normal brain, 1.53±0.25 in astrocytoma, 2.37±0.71 in malignant astrocytoma. And 2.88±0.41 in glioblastoma multiforme. And there was a statistically significant difference among these. The results show that Ag-NOR technique is a rather simple and rapid method and will become a helpful tool for estimation of the proliferative potential of glioma.

Abstract PDF: A total of 53 gastric adenomas from endoscopically biopsied gastric mucosa were examined histopathologically. The average age at the time of endoscopic biopsy was 59 years, and gastric adenomas were found to be more frequent in the aged, particularly above the age of 50. The majority of adenomas occurred at the antrum. Concerning the shape of the adenomas, Yamada type II was more frequent (55%). All adenomas were accompanied by varying degree of intestinal metaplasia, and this findings suggest that gastric adenoma develops from intestinal metaplasia. In adenomas with severe atypia (grade III), endocrine cells (argyrophil and argentaffin cells) were markedly decreased or absent. Gastric adenocarcinomas coexistent with adenoma were seen in 5 (9.4%) out of 53 cases, and were more frequent in male than female patients (sex ratio, 4:1) and the average age was 61.4 years. It is suggested that there is a necessity of thorough follow-up study for definitive correlation between gastric adenoma and adenocarcinoma.

Abstract PDF: The purpose of this study was to evaluate the influence of high dose carbon tetrachloride (CCI4) on the hepatotoxic effect of dimethylnitrosamine (DMN) which induces acute hemorrhagic necrosis in liver. Rats were injected intraperitoneally DMN dissolved in physiologic saline by a dose of 40 mg/kg. For changes related to CCI⁴ pretreatment, rats were injected intraperitoneally CCI⁴ dissolved in olive oil by a dose of 0.4 mg/kg, and then injected DMN. The livers were extracted from the rats 3, 6, 12, 24, 48, 72, and 120 hours after CCI⁴ and/ or DMN injection. Liver tissues were examined with light and electron microscopes. The results were summarized as follows; Light microscopic findings: Severe centrilobular hemorrhagic necrosis developed from 12 hours after injection of DMN and continued to 120 hours. On injection of DMN after CCI4 pretreatment, Massive necrosis occurred early. But active regenerative changes were produced in 24 hours. In 120 hours, the liver recovered in almost normal appearance. The degree of necrosis in pretreated group was similar to that in DMN injection only, and the time of recovery was faster in pretreated group. Electron microscopic findings: The early change was mainly disorganization of RER in DMN injection, and clumping and vesicular dilatation of ER in injection of CCI4. In pretreatment group, the early change was similar in appearance with CCI4 group, but severer in degree. According to the results, it was revealed that acute toxic effect of DMN was recovered more rapidly in pretreatment group. Thus it was suggested that CCI4 had protective effect in DMN hepatotoxicity.

Abstract PDF: This study was designed to investigate the effect of GABA and related substances on the spontaneous contraction of rat small intestine. The rats (Sprague-Dawley), weighing 200-250g, were sacrificed by cervical dislocation, and the small intestine was isolated. Longitudinal muscle strips from duodenum, jejunum and ileum were suspended in Biancani's isolated muscle chambers and myographied isometrically. GABA and muscimol, a GABA A receptor agonist relaxed the duodenum and jejunum significantly, but baclofen-induced relaxation in those muscle strips negligible. The effectiveness of GABA and muscimol in various regions were the greatest on duodenum, and greater on jejunum than on ileum The effect of GABA and muscimol was antagonized by bicuculline, a competitive GABA A receptor antagonist and picrotoxin, a noncompetitive GABA A receptor antagonist. Duodenal relaxation induced by GABA and muscimol was unaffected by hexamethonium, but was prevented by tetrodotoxin. These results suggest that GABA inhibit the contractility of smooth muscle with distinct regional difference of efficacy, and the site of inhibitory action is the GABA A receptor existing at the presynaptic membrane of postganglionic excitatory nerves.

Abstract PDF: We have reviewed seven cases of fracture-separation of the distal humeral epiphysis, one of which was initially misdiagnosed as a fracture of the lateral condyle. There were difficulties in making the diagnosis. The injury must be distinguished from an elbow dislocation and a fracture of the lateral humeral condyle. All seven patients revealed posteromedial displacement of the distal humeral epiphysis on initial x-rays. Three patients were treated by closed reduction and cast immobilization, and four patients by open reduction and internal fixation. All three patients with conservative treatment had slight cubitus varus (under 5 degrees). Two patients with operative treatment had significant deformities of the elbow, one 25 degrees of valgus and one 20 degrees of varus. In treatment of these injuries, accurate evaluation of the state of reduction is most important. We got acceptable results with a conservative treatment.

Abstract PDF: Peritoneal dialysis has been widely considered to be the dialytic treatment of choice for acute renal failure in infants and young children, because the technique is simple, safe and easily adapted for these patients. Also peritoneal dialysis in infants might have more effective ultrafiltration and clearance than in adults. In certain circumstances associated with hemodynamic instability, ordinary volume peritoneal dialysis (30-50 ml/kg body weight per exchange) or hemodialysis may not be suitable unfortunately. But frequent cycled, low volume, high concentration peritoneal dialysis may be more available to manage the acute renal failure of newborns and infants. Seven infants underwent peritoneal dialysis for hemodynamically unstable acute renal failure with low exchange volume (14.2±4.2 ml/kg), short exchange time (30 to 45 minutes) and hypertonic glucose solution (4.25% dextrose). Age was 1.9±1.3 months and body weight was 4.6±1.6 kg. Etiology of acute renal failure was secondary to sepsis with or without shock (5 cases) and postcardiac operation (2 cases). Catheter was inserted percutaneously with pigtail catheter or Tenkhoff catheter by Seldinger method. Dialysate was commercially obtained Peritosol which contained sodium, chloride, potassium, magnesium, lactate and calcium. Net ultrafiltration (ml/min) showed no difference between low volume dialysis and control (0.27±0.09 versus 0.29±0.09). Blood BUN decreased from 95.7±37.5 to 75.7±25.9 mg/dl and blood pH increased from 7.122±0.048 to 7.326±0.063 after 24 hours of peritoneal dialysis. We experienced hyperglycemia which were controlled by insulin (2 episodes), leakage at the exit site (2), mild hyponatremia (1) and Escherichia coli peritonitis (1). Two children of low volume dialysis died despite the treatment. In our experience, low volume and high concentration peritoneal dialysis with frequent exchange may have sufficient ultrafiltration and clearance without significant complications in the certain risked acute renal failure of infants.
