A 15-year-old female with primary amenorrhea and Tuner's syndrome feature was referred for a chromosome analysis. The karyotype of the patient was 45,X/46,X,der(Y) mosaicism under initial GTG-banding analysis. Fluorescence in situ hybridization (FISH) analysis with probe for CEP X probes and SRY probe (Vysis, Inc. Downers Grove, IL 60515, USA) was carried out. This probe is direct labeled with SpectrumOrange (SRY, Yp11.3) and is available as a single probe or mixed with the CEP X SpectrumGreen probe. SRY SpectrumOrange/CEP X SpectrumGreen hybridized to a specimen obtained from an two isodicentric Y chromosomes. The karyotype of the patient was ish Xcen(DXZ1x1)/Xcen(DXZ1x1), Yp11.3(SRYx2) by using FISH. This karyotype was considered a variant of Tuner syndrome with mixed gonadal dysgenesis (MGD), male pseudohermaphroitism (MPH) and apparently normal male.

This study was aimed to clerify the cytotoxicity of some plant extracts such as Hosta longissima HONDA (HL), Hemerocallis fulva var. Kwanso REGL (HFVK), Hemerocallis fulva L (HF), Macrocapium officinale NAKAI (MO) and Mentha canadensis var. piperascens HARA (MCVP), the cultured NIH3T3 fibroblasts were treated with 25, 50, 100, 150 and $200{\mu}g/mL$ of five kinds of plant extracts for 48 hours, respectively. The cytotoxicity of plant extracts was measured by MTT and NR assays for the cell viability, and XTT assay for the cell adhesion activity. In this study, HL, MO and FHVK extracts showed the range of midtoxic-non toxic by the criteria of chemical cytotoxicity. While, the HF and MCVP extracts showed midtoxic. In the extract cytotoxicity, HL, MO and FHVK extracts showed non-toxic by the criteria of extract cytotoxicity. While, HF extract was determined as lower-toxic. In the responsive sensitivity of each plant extract on colorimetric assays, HF extract was sensitive to mitochondrial enzyme by MTT assay, lysosomal enzyme by NR assay and mitochondrial nucleus by XTT assay. While, MCVP extract was sensitive to mitochondrial enzyme by MTT assay and lysosomal enzyme by NR assay than other assays. While, HL, HFVK and MO extracts were most sensitive to NR assay. Cell culture is one of useful materials in the screening of cytotoxic and recovary effect on the putative chemical agents or plant extract. And also, colorimetric assay is regarded as very useful tools for quantitative measurement of cytotoxic effect on plant extracts in vitro.

HbA1c test measures the amount of glycated hemoglobin in blood. HbA1c shows the average of blood glucose levels for the past three months, this is a better indicator of how overall diabetes is doing. HbA1c gives a much better idea of how the body is breaking down the glucose. Therefore, this HbA1c is very important tool for maintaining normal glucose levels for pre-and diabetic patients. Total 408 participants were tested HbA1c voluntarily from Chosunilbo Health Expo (8th~11th, July 2010). Through this small-scaled direct HbA1c, about 54.7% (207 out of 408) was shown glucose tolerance and diabetes. However, 61 from 157 participants who were shown under 6.9% HbA1c (normal and pre-diabetic stage) are taking only antidiabetic drugs to maintain a normal blood glucose. Regular HbA1c test can bring an important management and awareness about controlling blood sugar level and prevention of diabetic complications.

This study was performed to determine the risk factors associated with increased body mass index (BMI) in 672 heavy industry men workers. Subjects were examined in March, 2010 to September, 2010 in Gyeongnam province. Height, weight, systolic blood pressure, and diastolic blood pressure were measured. And fasting blood glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride levels were measured by Olympus AU 680, and their BMIs calculated. Age, smoking statue, and alcohol drinking of the workers were surveyed by questionnairs. The mean total cholesterol levels were $190.06{\pm}36.62mg/dL$, HDL-cholesterol $53.65{\pm}11.92mg/dL$, LDL-cholesterol $104.28{\pm}30.31mg/dL$, triglyceride $151.11{\pm}99.53mg/dL$, and fasting blood glucose $96.92{\pm}19.53mg/dL$. Mean systolic blood pressure was $126.08{\pm}13.78mmHg$, and diastolic blood pressure $71.88{\pm}10.45mmHg$. Subjects were categorized into two BMI groups, BMI ${\geq}23$ and BMI ${\leq}22.9$. The subjects with BMI of 23 or above had significantly higher levels of LDL-cholesterol, systolic blood pressure, and triglyceride, with lower levels of HDL-cholesterol. BMI showed the highest level at the age of thirties, increasing with age. BMI of smokers was higher than BMI of non-smokers, not showing a link between alcoholics and non alcoholics. In conclusion, age, systolic blood pressure, and HDL-cholesterol are mostly relevant to the increase of BMI in this study.

Cadmium (Cd) is known to exert gonadotoxic and spermiotoxic effects. The present study was performed to investigate the morphological effects and metallothionein (MT) expression by zinc pretreatment in the course of time of cadmium-induced testicular injury in rat. Fifty male Spraque-Dawley rats weighing 160-180 g were divided into two groups: saline-pretreated cadmium group and zinc-pretreated cadmium group. Rats of two groups received subcutaneous injection of saline and 100 mg/kg $ZnSO_4$ at 0, 2, 5 and 8 hrs intervals respectively. Cadmium chloride (4.5 mg/kg $CdCl_2$) was administrated intraperitoneally at 2 hr after zinc injection and rats were killed 0, 12, 24, 48 and 72 hrs later. Testicular tissue damages, Interstitial (Leydig) cells status and MT expression were determined using hematoxylin-eosin stained sections and a computerized image analysis system on sections immunostained with a mouse anti-metallothionein respectively. Zinc pretreatment was significantly reduced testicular damages in five pathological categories after cadmium administation. The number of surviving interstitial cells was significantly higher in the zinc-pretreated group than in the saline-preatreated group at 48 and 72 hrs after cadmium administration. Non-damaged testis showed the positivity of MT staining in spermatogenic cells, Sertoli cells and endothelium of blood vessel, but not in the Leydig cells. The potitivity of MT staining in saline-pretreated group was significantly reduced at 24 hrs after cadmium administration, whereas zinc-pretreated group showed strong MT positive staining similar to the 0 hr by 42 hrs after cadmium administration. In damaged testis, MT positive staining was also observed in the Leydig cells of both groups. These results suggest a major preventive effect of zinc against cadmium-induced testiculat toxicity may be due to its ability to reduce the cytotoxicity of cadmium in spermatogenic cells and Leydig cells by inhibiting the susceptibility of the testis to cadmium but not MT production by cadmium.

To improve accuracy of the immunohistochemical testing and fluorescence in situ hybridization (FISH) study as well as a routine histology diagnosis in breast cancer, quality improvement for optimal tissue handling is mandatory. We evaluate fraction defective of 7107 blocks from 349 breast cancer patients, who underwent surgical treatment at Samsung Medical Center Seoul, Korea from January 1, 2009 to March 31, 2010. We decided pre-improvement period from January, 2009 to June, 2009. In the first quality improvement period (July, 2009 to September, 2009) we made improvements in protocol of gross examination. In the second quality improvement period (October, 2009 to December, 2009) we attempted more effective formalin fixation such as frequent exchange of formalin and use of separate fixation container for each case. In the third quality improvement period (January, 2010 to March, 2010) improvement of tissue processor was performed. We achieved a marked reduction of fraction defective (9-16%) through efforts to improve quality of formalin-fixed, paraffin-embedded blocks when compared to pre-improvement period.

Transcranial Doppler ultrasonography (TCD) allows measurement of blood flow velocity to be made from the basal intracerebral vessels. Blood flow velocity in TCD is highly affected not only by blood vessel diameter, blood flow volume, blood viscosity, but also age and sex. Therefore, the study is focused on the correlation between TCD measurement index and sex/age. Subjects were 214 (male 147, famale 67) who had TCD for headache and stroke evaluations at Dongguk University Ilsan Hospital neurology department from December 2009 to April 2010. Sex did not show significant differences with mean flow velocity (MFV), peak systolic flow velocity (PSFV), end diastolic flow velocity (EDFV), pulsatility index (PI) and resistance index (RI) in middle cerebral artery (MCA). Although age also did not show significant differences with MFV and PSFV, EDFV has statistically decreased with age, and PI and RI has statistically increased with age. In addition, age showed significant correlation with MFV, EDFV, PI and RI, but not with PSFV. Therefore, TCD is definitely correlated with age and sex, so that those influencial factors must be considered when being tested.
