We experienced a case of Turner variant in 17 year old girl. She showed normal appearance except short stature. The patient was born at term with a birth weight of 2200g and her height was below the 3 percentile at admission. Thelarche appeared at the age of 13 years. FSH and LH levels were elevated, estradiol was within normal range, but progesterone level was decreased, bone age was 14 to 15 year old, and the small sized uterus was detected by abdominal ultrasonogram. Karyotype analysis revealed 46,XXp+(Xqter-->Xp22::Xp22-->Xqter). Her height didn't grow properly despite serial growth hormone therapy, because her epiphyseal growth plate was nearly closed.

This study was designed to validate the usefulness of the near point of convergence(NPC)test in determination of dominant & non-domnant eyes in intermittent exotropia patients. We performed NPC test in 36 intermittent exotrpic patients, and then, determined the non-dominant eye which deviated outward beyond the NPC. The dominant eyes determined by the NPC were compared to those that were determined by amblyopia, sensory fusion and photophobia. Best corrected visual acuity was used to divide patients into two groups : 26 patients without amblyopia, and 10 with amblyopia. Among the amblyopia group, if the eyes with better visual acuity were taken as dominant eyes, then eight(80%)cases were identical with the NPC test and two(20%)cases were different. Ten patients had sensory anomaly, and among then, nine(90%)cases were identical with the NPC test and one(10%)case was different. Twenty six(64%)patients had photophobia in one eye and all(100%)cases were identical with the NPC test. In intermittent exotropia, determination of dominant eye by the NPC test showed high coincidence with other tests. Therefore, we suggest that the NPC test is an easy and accurate method in determining either the dominant or non-dominant eye for surgery.

BACKGROUND: Doppler echocardiography is a non-invasive technique that has been used to evaluate LV diastolic dysfunction. Impaired left ventricular diastolic filling is known to occur in patients with coronary artery disease. Compared with those in normal subjects, Doppler-derived transmitral blood flow velocities have been reported to be reduced during early diastolic filling and to be compensatory elevated subsequent to atrial systole in patinets with coronary artery disease. But stiffness of myocardium normalize the E/A ratio, and normal E/A ratio may reveal increased ventricular filling pressure. We tried to investigate left ventricular filling parameters by Doppler echocardiography in patients with early myocardial infarction, and to compare left ventricular diastolic function regarding infarct location on EKG, one or multivessel disease on coronary angiography, and treatment modality. METHODS: From September 1993 to August 1995, Pulsed wave Doppler echocardiography was performed in patients with early acute myocardial infarction(N=95) and control group(N=20) within 5 days after admission, and parameters of diastolic function was evaluated. RESULTS: Echocardiographic data showed significant differences in mean ejection fraction, mean left ventricular mass, and mean left ventricular mass index between two groups. There was no significant difference in E/A ratio, deceleration time, and isovolumetric relaxation time between two groups. Neither, there was significant difference in each diastolic parameter for infarct related wall on EKG. And there was no significant difference in deceleration time for one or multi vessel disease on coronary angiography, treatment modality(conservative treatment, thrombolytic therapy, or primary PTCA). CONCLUSION: In patients with early acute myocardial infarction, left ventricular diastolic dysfunction was absent. And there was no significant correlation between the presence of diastolic dysfunction and the location of infarct related wall on EKG, or one or multi vessel disease, or treatment modality.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.
