Cardiac size of 291 new-born infants was measured using the method illustated on Fig 1. Among the 291 infants,53 were asphyxiated, and asphxia was only regared from Apgar score below 6 on 1 min. and 5 min. Remaining 238infants were normal, and classified to group with lung abnormalities and without lung abnormalities on chest A-Pfilm. The results are as follows; 1. The average CTR. of normal group was 52.37(C/T1;54.89, C/T2;49.43, C/T3;49.15, C/T;55.97) 2. The average CTR. of asphxiated group was 54.91 (C/T1;57.13, C/T2;51.69, C/T3;51.94,C/T4;58.25) 3. Consequently, asphyxiated infants revealed larger cardiac size than normal infant group.

The double-chambered right ventricle is congenital or acquired cardiac anomaly, which is characterized by aberrent hypertrophied muscular bands that divide the right ventriclar cavity into two different pressure chamber. This anomaly can complicate the natural history of patient with isolated ventricular septal defect. We experienced two cases of cases of acquired DCRV, which confirmed by two separate cardiac catherterization and angiography. The purpose of this report is to show that the aberrant muscular bands may be nonobstructive in early infancy and that the obstructive effect is developed with time as the bands become progressively more hypertrophied.

Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.

Acute necrotizing encephalopathy is a recently established disease entity, proposed by Mizuguchi et al in 1995, that shows a characteristic symmetric and multifocal involvement of both thalamus, brainstem tegmentum, cerebral periventricular white matter, and cerebellar medulla. It is known to be prevalent in Japan and other Far Ease countries. The etiology of the acute necrotizing encephalopathy remains unknown. The typical course of acute necrotizing encephalopathy is the development of the irreversible neurologic symptoms related to brain lesions. The diagnosis can be made on the basis of the combination of a typical clinical profile and characteristic radiologic findings. We experienced a first case of acute necrotizing encephalopathy in a 9 month old boy in Korea. We report this case with the brief review of related literatures.

We evaluated the accuracy of a noninvasive method for estimating right ventricular systolic pressures in patients with atrial septal defect and tricuspid regurgitation defected by two-dimensional and Doppler ultrasound. Of 54 patients with atrial septal defect, 24(44%) had jets of tricuspid regurgitation. By use of the maximum velocity(V) of the regurgitatant jet recorded by continuous wave Doppler ultrasound and the Bernoulli equation, we predicted right ventricular systolic pressure(RVP) calculated by the equation of RVP=4V2+10 proposed by Tei et al.The values correlated well with catheterization values(r=0.851, standerd error of estimate=4mmHg). In addition the relation between the Lt to Rt shunt amount and the severity of tricuspid regurgitation was assessed. The severity of tricuspid regurgitation graded on a four-pointscali by pulsed Doppler and two-dimensional echocardiography correlated with Qp/Qs ratio calculated by the Fick's method(p<0.05).

In the practice of modern craniomaxillofacial surgery, there is a general agreement in favor of obtaining solid bony union through the use of titanium and vitallium rigid fixation. These metallic osteosynthesis are not free from inherent drawbacks and limitation. They are liable to have an adverse effect on the growth of the craniofacial skeleton, be a cause of secondary bony resorption, increase risk of infection, result in palpability or exposure and cause artifact in radiologic imaging. These can lead to undue secondary operations necessitating their removal. To overcome there shortcomings, there had been a continuous research on the development of a bioabsorbable skeletal fixation system using polymer of polylactic and polyglycolic acid. Recently, with introduction and commercial availability of a product(Lactosorb, Walter Lorenz) with a minimized resorption period and foreign body reaction, there is an increasing acceptance of its use as an alternative fixation device in craniomaxillofacial surgery. In effort to extend its use in facial bone fractures, Tatum and Eppley were the first report in its successful application in a clinical setting. We report on the clinical experience of such bioabsorbable rigid fixation in patients with maxillofacial trauma. In included one adult and three children in their growth period, underwent open reduction of facial bone fractures. They were followed up in terms of clinical and radiologic outcome for six months. Stalbe and adequate longterm fixation was obtained and no recurrences were noted.

Hysterosalpingograms of 375 patients with infertility were reviewed with reference to radiological features of each pathology and a comparative study of hysterosalpingography and laparoscopy in 36 patients was presented. The results were as follows; 1. In 375 cases infertility, 191 cases (50.9%) were primary infertility and 181 cases(49.1%) were secondary infertility. 2. The peak age distribution was 26 to 30 year old group in 211 cases (56.3%),and the peak duration of infertility was less than 3 years in 256 cases (68.3%). 3. Abnormal uterine findings were 115 cases (30.7%) and there were 73 cases of filling defects, 13 cases of irregularity , 12 cases of uterineflexion, 11 cases of congenital anomaly, and 9 cases of hypoplasia among them. 4. Abnormal tubal findings were 196 cases (52.3%) and there were 103 cases of simple obstruction, 69 cases of hydrosalpinx, and 50 cases of peritubal adhesion among them. 5. Intravasation of contrast media was noted in 42 cases (11.2%). 6. In 36 cases of laparoscopy, 23 cases (63.7%) was agreed to hysterosalpingography. 7. Aothough laparoscopy was better than hysterosalpinography in external anatomy of salpinx and relationship to overay, hysterosalpingography should be important for fundamental study of infertile women because of lower failure rate, lower risk of complications,therapeutic effect, and lower cost.

Oxidative stress can cause generation of uncontrolled reactive oxygen species (ROS) and lead to cytotoxic damage to cells and tissues. Recently, it has been shown that transient ROS generation can serve as a secondary messenger in receptor-mediated cell signaling. Although excessive levels of ROS are harmful, moderated levels of ROS are essential for normal physiological function. Therefore, regulating cellular ROS levels should be an important concept for development of novel therapeutics for treating diseases. The overexpression and hyperactivation of NADPH oxidase (Nox) can induce high levels of ROS, which are strongly associated with diabetic nephropathy. This review discusses the theoretical basis for development of the Nox inhibitor as a regulator of ROS homeostasis to provide emerging therapeutic opportunities for diabetic nephropathy.

Blood glucose homeostasis is well maintained by coordinated control of various hormones including insulin and glucagon as well as cytokines under normal conditions. However, chronic exposure to diabetic environment with high fat/high sugar diets and physical/mental stress can cause hyperglycemia, one of main characteristics of insulin resistance, metabolic syndrome, and diabetes. Hyperglycemia impairs organogenesis and induces organ abnormalities such as cardiac defect in utero. It is a risk factor for the development of metabolic diseases in adults. Resulting glucotoxicity affects peripheral tissues and vessels, causing pathological complications including diabetic neuropathy, nephropathy, vessel damage, and cardiovascular diseases. Moreover, chronic exposure to hyperglycemia can deteriorate cognitive function and other aspects of mental health. Recent reports have demonstrated that hyperglycemia is closely related to the development of cognitive impairment and dementia, suggesting that there may be a cause-effect relationship between hyperglycemia and dementia. With increasing interests in aging-related diseases and mental health, diabetes-related cognitive impairment is attracting great attention. It has been speculated that glucotoxicity can result in structural damage and functional impairment of brain cells and nerves, hemorrhage of cerebral blood vessel, and increased accumulation of amyloid beta. These are potential mechanisms underlying diabetes-related dementia. Nutrients and natural food components have been investigated as preventive and/or intervention strategy. Among candidate components, resveratrol, curcumin, and their analogues might be beneficial for the prevention of diabetes-related cognitive impairment. The purposes of this review are to discuss recent experimental evidence regarding diabetes and cognitive impairment and to suggest potential nutritional intervention strategies for the prevention and/or treatment of diabetes-related dementia.
