During the period of 4 years from May, 1981 to April, 1985, 71 cases of obstructing subinfundibular muscular bundles of the right ventricle in congential cardiovascular anomalies were diagnosed by cariac catheterization and angiography at Hanyang University. The finding of right ventricular angiogram and degree of the right ventricular outflow obstruction, clinical data, electrocardiographic data and hemodynamic data were correlated irrespectively. The summary of this article is as follows. 1) The age of patients was ranged from 1 to 22 years old with a mean age of 8 years old. There were 39 males and 32 females with M:F ratio of 1.2:1. The incidence of obstructing subinfundibular muscular bundles of the right ventricle in congenital cardiovascular anomalies was higher with increasing age. 2) The associated cardic anomalies were as follows: 40 cases (56%) of isolated ventricular septal defect(VSD), 13(18%) of tetralogy of Fallot physiology, 7(10%) of patent ductus arteriosus(PDA), 3(4%) of pulmonary stenosis, 1 aortic stenosis, 1 double outlet of right ventricle(DORV), 1 trilogy, 1 ostium secundum defect, etc. The incidence of VSD with or without other associated cardiovascular anomalies was 56 cases(79%) out of 71 cases. 3) Maximum systolic pressure gradient between proximal and distal chamber of the right ventricle were under 25 mmHg in 32 cases, between 25 and 50 mmHg in 13 and above 50 mmHg in 26. Pressure gradients of all 7 cases with PDA were under 25 mmHg. 4) Correlative assesment of angiographic manifestation(2 indicies:Diameter of right ventricular outflow tract(systolic phase)/diameter of tricuspid valvular annulus(diastolic phase)=OT/TV, Diameter of right ventricular outflow tract(systolic phase)/Length of right ventricular diaphragmatic surface(systolic phase)=OT/RV) according to pressure gradient, OT/Tv and OT/RV values were lower the increasing pressure gradient, between proximal and distal chamber of the right ventricle. These were reverse correlations but coefficients of correlation(r) were-0.49and -0.48. Therefore, the degree of right ventricular outflow obstruction could be predicted, using 2 indices of right ventricular angiogram in individual cases, but could not be calculated accurately. 5) This indicated that pressuer gradient was also affected by technical errors, variable cardic anomalies, development of sinusoid, age and the other factors. 6) We assumed that non-invasive Doppler echocardiography could be useful in making the diagnosis and follow up of the patient with obstructing subinfundibular muscle bundles in right ventricle.

Ganglioneruroblastoma and neuroblastoma are among commonest types of childhood malignancy and a number of unique paraneoplastic syndromes have associated with both localized and disseminated neuroblastoma. The coincidence of neuroblastoma and myoclonic encephalopathy or other paraneoplastic syndromes occurs relatively rare, and therefore, failure to recognize this association could result in delays in both diagnosis and treatment, and the result could prove to be unfortunately fatal. The mechanism which underlies the remote damaging effect of neural crest tumor, especially neuroblastoma, on the nervous system resulting in myoclonic encephalopathy is by no means clear. In addition the nature and the extent of the pathologic lesion are inconsistent. We experienced a case of myoclonic encephalopathy associated with an occult mediastinal ganglioneuroblastoma in a 22-month-old girl who was hospitalized for inability to walk without support and tilting of the head to the left side. She became increasingly ataxic, and during the hospitalization myoclonic jerks of upper extremities and head along with chaotic, rapidly flickering, multidirectional spontaneous eye movements, were noted. Laboratory data included normal complete blood count, urinalysis, BUN and creatinine, electrolytes and bone marrow. Chest X-ray and chest CT revealed a relatively well marginated right posterior mediastinal mass. In a 24 hours urine excretion test, VMA and catecholamines were increased. Over the next 2 weeks, a surgical exploration revealed a right posterior mediastinal mass. Microscopically the mass proved to be a ganglioneuroblastoma, extending to right innominate artery and right axillary lymph nodes. Within 2 weeks after the surgery, radiotherapy (2,400 rads) and chemotherapy (CTX, DTIC, VCR) were started, but corticosteroid was not used. She has been free of tumor and abnormal neurological systemic symptoms and signs for 1 1/2 year since the completion of chemotherapy. In the 3 1/2 years follow-up period, her neurologic symptoms has completely resolved by the completion of 2 years chemotherapy. We report a case of mycoclonic encephalopathy associated with hidden ganglioneuroblastoma in 22-month-old girl.

The purpose of this study was to compare surface roughness and bone formation around two types of threaded commercially pure titanium implants manufactured by two different companies. The test implants were manufactured by Sumin synthesis dental materials Co. (Avana, Busan, Korea), while the controls were manufactured by Nobel Biocare (MK II, Goteborg, Sweden). To compare bone formation adjacent to newly product with Branemark MK II implant, surface roughness was measured by Accurate 1500M and histomorphometric analysis was done. The results were as follows : 1. Measurement of surface roughness showed that Avana implant had a slightly more irregular surface compared with Branemark implant. 2. In the light microscopic studies, no infiltration of inflammatory cells nor the giant cells wee observed on both groups. 3. In th light and fluorescent microscopic studies, the amount of osseointegration and the extent and the timing of bone formation were similar. 4. There were no statistically difference between two groups in the average bone to implant contacts. Branemark implant ; 67%(SC 23%), Avana implant ; 70%(SD 16%). Comparing with Branemark implant, Avana implant made of CP grade II titanium showed similar good bone healing, formation and osseointegration.

The potential mechanism by which sodium-glucose cotransporter 2 (SGLT2) inhibitors prevent cardiovascular disease (CVD) is being widely investigated. Improved insulin resistance, along with decreased body fat mass associated with SGLT2 inhibitor treatment is consistent with previously well-established factors contributing to the prevention of CVD. These factors are responsible for reduction of oxidative stress as well as improvement of systemic inflammation. Because heart failure was one of the most dramatically improved cardiovascular events in various clinical trials and because SGLT2 inhibitors promote osmotic diuresis and natriuresis, hemodynamic changes are considered as a critical mechanism responsible for the cardioprotective effect of SGLT2 inhibitors. Restored tubuloglomerular feedback by SGLT2 inhibitors might play a role in renoprotection, which in turn, leads to fewer CVDs. Finally, blood ketone body increments in response to SGLT2 inhibition might act as a “super-fuel” for salvaging the failing diabetic heart.

In the present study we first report in Korea the identification and characterization of Fusarium oxysporum isolated from rotten stems and roots of paprika (Capsicum annuum var. grossum) at Masan, Kyungsangnamdo in 2006. The fungal species produced white aerial mycelia accompanying with dark violet pigment on PDA. The optimal temperature and pH for the growth of the species was 25degrees C and pH 7, respectively. Microscopic observation of one of isolates of the species shows that its conidiophores are unbranched and monophialides, its microconidia have oval-ellipsoidal shape with no septate and are of 3.0~11 x 1.5~3.5 microm sizes, its macroconidia are of 15~20 x 2.0~3.5 microm sizes and have slightly curved or slender shape with 2~3 septate. The results of molecular analysis show that the ITS rDNA of F. oxysporum from paprika shares 100% sequence identity with that of known F. oxysporum isolates. The identified species proved it's pathogenicity by causing rotting symptom when it was inoculated on paprika fruits. The growth of F. oxysporum from paprika was suppressed on PDA by agrochemicals such as benomyl, tebuconazole and azoxystrobin. The identified species has the ability of producing extracelluar enzymes that degrade cellobiose and pectin.
