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.

This study included 38 children patients of less than 4 years old and 18 kg body weight. After 8 hours of starvation, the children were divided into 2 groups: Group I received Hartmann's solution and Group II received Hartmann's dextrose solution. In both groups, the rates of infusion were 10 ml/kg/hr before and during operation and blood samples were collected just before and 1 hr after induction of anesthesia, respectively. The results were as follows; 1) In the Group I, blood glucose concentration just before induction was decreased than control values that was checked at ward, and 1 hr value after induction was significantly increased then control values. 2) In the Group II, blood glucose concentration was increased just before and 1hr after induction than control values significantly respectively. 3) In the blood glucose concentration 1 hr after induction, difference between Group I and Group II was not significant. 4) In children, duration of starvation about 8 hrs did not significant influence on blood glucose concentration although dextrose was not administered.

We have recently experienced a clinically atypical case of malignant histiocytosis involving the spleen, ileum and bone marrow, in a 25-year-old Korean male. He was admitted to our hospital because of multiple purpuric lesions of skin which had been appearing since 2 years ago. Physical and laboratory examinations revealed marked splenomegaly with pancytopenia. With clinical impression of hypersplenism, splenectomy was performed. During the operation, the surgeons found a dark red mucosal lesion in the ileum incidentally, to resect the segment. Microscopic findings of the spleen and the ileal lesion showed extensive proliferation of atypical histiocytes, many of them phagocytosing numerous erythrocytes. Bone marrow biopsy was done for follow-up study, which showed increased cellularity with infiltration of atypical histiocytes.

BACKGROUND: Cardiac hypertrophy is an adaptive mechanisms in response to an increased cardiac work load. Alterations in gene expression play an important role in this adaptive process. Recent investigations have indicated that the alpha-1 adrenergic stimulation in vitro induces hypertrophic change of neonatal cardiomyocytes. The signalling mechanisms of this alpha-1 agonist induced cardiomyocyte hypertrophy are largely unknown. however, recent evidence favors an effector pathway that involves phospholipase C(PLC) mediated hydrolysis of phosphatidylinositol 4,50 bisphosphate. It should be recognized that the demonstration of enhanced phosphoinositol turnover in the presence of alpha-1 adrenergic agonist in vitro does not necessarily imply that a similar response is operative in vivo. Furthermore, the role of subtypes of phospholipase C in this system should be determined. In this context, we produced in vivo cardiac hypertrophy by repeated injection of alpha-1 adrenergic agonist, phenylephrine, and tried to evaluate any change of phospholipase C subtypes by immunohistochemistry and immunoblotting technique and also measured the phosphatidylinositol hydrolyzing activity of the enzyme. METHOD: To produce cardiac hypertrophy, we injected phenylephrine 12mg/kg i.p. to the 28 female S-D rats weighing 150-250g daily for 5 days. This measures produced 22% increase of heart weight/body weight ratio. After 5 days. rats were sacrificed and hearts were rapid excised and freezed for next procedure. The immunohistochemical stainings of myocardium were carried out using monoclonal antibodies against PLC-beta1,-gamma1,-delta1 with Avidine-Biotin Complex method. Immunoblotting was done with monoclonal anti-PLC-gamma1 antibody after immnoprecipitation. The activity of PLC-gamma1 was determined in the assay mixture containing [3H] phosphatidylinositol of 20,000 cpm. The reaction was performed by incubating with resuspended immunoprecipttol of 20,000 cpm. The reaction was performed by incubating with resuspended immunoprecipitate for 10 min and supernatant was collected for -scintillation counting. RESULTS: Immunohistochemical staining demonstrated increased staining of PLC-gamma1 in the phenylephrine induced hypertrophied heart as compared with normal control heart. PLC-beta1 and-o1 did not showed any change. Elghteen out of 20 hypertrophied cardiac tissue(90%) demonstrated increased expression of the PLC-gamma1 compared with control heart tissue in immunoblotting. [3H] PI hydrolyzing activity of PLC-gamma1 in the immunoprecipitates of the hypertrophied hearts(4650+/-614 cpm) were increased consistently in 6 samples as compared with control normal hearts (2387+/-651 cpm). CONCLUSION: In the present experiments we demonstrated that Phospholipase C-gamma1 was overexpressed compared with control normal heart of rat by immunohistochemistry and immunoblotting technique and showed that the activity of this isoenzyme was elevated. Our findings of increased PLC-gamma1 expression in the alpha1-adrenergic agonist induced cardiac hypertrophy tissue suggest that the phosphatidylinositol signalling pathway is important in the genesis of cardiac hypertrophy and the isoenzyme of PLC-gamma1 may play a central role in this mechanism.

PURPOSE: The purpose of this study was to investigate relationships between the symptoms of Restless Legs Syndrome (RLS), sleep disturbance and depression among middle-aged women. METHODS: The study took a descriptive approach. A self-reported questionnaire was provided to women aged between 45 and 65 living in community area. The data were analyzed via SPSS program (version 25). RESULTS: 47.8% of the respondents showed moderate to severe RLS symptoms and the severity of RLS symptoms was 10.72. Depression score was 13.12 and sleep disturbance score was 4.97. There was a significant correlation between RLS symptoms and sleep disturbance (r=.423, p < .001), and RLS symptoms had a positive impact on sleep disturbance. There was also a significant correlation between RLS symptoms and depression (r=.494, p < .001) and RLS symptoms also had a positive impact on depression. CONCLUSION: Women with RLS symptoms had more severe sleep disturbance, depression and vasomotor syndrome than those without RLS symptoms. If RLS symptoms among middle-aged women is simply diagnosed as a menopausal symptom, this misdiagnosis can lead to sleep disorder and depression. Therefore, further empirical researches should be done to estimate the prevalence of RLS symptoms and to launch a program to detect RLS at the early stage.

PURPOSE: The purpose of this study was to investigate relationships between the symptom of restless legs syndrome (RLS), somatic symptom, depression, and activities of daily living (ADL) among the elderly. METHODS: A descriptive approach was taken in this study. Data were collected from May 23 to July 5, 2019 and 140 elderly people replied to the questionnaire. The data were analyzed by descriptive statistics, t-test, One-way ANOVA, Pearson's correlation coefficient, and χ² test. RESULTS: 48.6% of the respondents had RLS symptom and the severity of RLS symptom was 9.57±11.55. RLS symptom had a positive correlation with depression (r=.538, p<.001), with somatic symptom (r=.528, p<.001), with ADL (r=.308, p<.001), and with IADL (r=.360, p<.001). Depression had the most significant correlation with RLS symptoms. There were significant differences in depression, somatization, ADL, and IADL according to the RLS severity. CONCLUSION The results of this study showed that many elders experienced mild to severe RLS symptom. Also, the elderly with RLS symptom had more severe depression, somatic symptom, ADL, and IADL than those without RLS symptom in this study. Depression, somatic symptom, and ADL could be deteriorated if the RLS symptom is not diagnosed early.

OBJECTIVE: To evaluate the clinical and electrodiagnostic findings of ulnar neuropathy at the elbow. METHOD: Sixty-two patients with ulnar neuropathy at the elbow were reviewed retrospectively to establish causes, severity and type of neuropathy, symptom, sign, operation name and operative findings. RESULTS: 1) Of total 62 cases, 41 were male and 21 were female and the most often were in their forties and fifties. 2) The main cause of the neuropathy is bone deformity caused by previous fracture or dislocation (43.6%). 3) The symptoms observed were motor weakness (66.1%), sensory change (79%) and muscle atrophy (35.5%). 4) Forty-nine cases showed abnormality in nerve conduction study and needle electromyography study, and 9 cases showed abnormality only in the needle electromyography study. 5) On needle electromyography, sparing of flexor carpi ulnaris was shown in 50 cases (80.6%). 6) Operative treatment was performed in 15 cases. Among them, electrodiagnostic and operative diagnosis coincided in only 12 cases (80%). CONCLUSION: We conclude that above clinical and electrodiagnostic findings are useful for the diagonosis ulnar neuropathy at the elbow with consideration of etiology, localization and for the selection of operative treatment.
