Objective: The aim of this study was to assess the changes of follicular fluid (FF) and serum levels of cerebellin precursor protein 1 (cbln1) and betatrophin in patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) with a gonadotropin-releasing hormone (GnRH) antagonist protocol. Methods: Twenty infertile women with PCOS and 20 control women diagnosed as poor responders undergoing ovarian stimulation with a GnRH antagonist were included. Blood samples were obtained during ovum pick-up. Follicular fluid from a dominant follicle was collected from the subjects. Using enzyme-linked immunosorbent assays, FF and serum levels of cbln1 and betatrophin were measured in both groups of participants. Metabolic and hormonal parameters were also determined and correlated with each other. Results: Both groups of women had similar serum and FF betatrophin levels ($55.0{\pm}8.9ng/mL$ vs. $53.1{\pm}10.3ng/mL$, p=0.11). The serum and FF betatrophin levels of poor responders were found to be similar ($49.9{\pm}5.9ng/mL$ vs. $48.9{\pm}10.7ng/mL$, p=0.22). Conversely, the FF cbln1 levels of PCOS women were found to be significantly higher than the serum cbln1 levels ($589.1{\pm}147.6ng/L$ vs. $531.7{\pm}74.3ng/L$, p<0.02). The FF cbln1 levels of control participants without PCOS were significantly higher than their serum cbln1 levels ($599.3{\pm}211.5ng/L$ vs. $525.3{\pm}87.0ng/L$, p=0.01). Positive correlations were detected among body mass index, insulin resistance, serum insulin, total testosterone, and betatrophin levels in the PCOS group. Conclusion: Follicular fluid betatrophin and cbln1 concentrations may play a pivotal role on follicular growth in PCOS subjects undergoing IVF/ICSI with an antagonist protocol.

Deoxynivalenol (DON) is a common food borne mycotoxin and occurs predominantly in grains such as wheat, barley, oats, etc. DON induces systemic health problems such as loss of appetite, emesis and diarrhea in both human and farm animals. Reliable diagnostic parameters for DON intoxication are needed to prevent deep health impact. In order to establish useful diagnostic parameters, we investigated clinical signs, hematological values, serum biochemical values, gross-, histo- and toxico-pathological findings in B6C3F1 male mice after oral administration of DON (0.83, 2.5 and 7.5 mg/kg) for 8 days. Body weight gain was significantly decreased at the highest dose of DON. Anorexia, ataxia, for crudness and lack of vigor were observed at the highest dose DON group. In hematological values, the numbers of WBC and platelets and hemoglobin content were reduced with decreased neutrophil and monocytes by 7.5 mg/kg DON. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were prolonged in a dose-dependent manner and the content of fibrinogen was elevated at high dose of DON. Of serum biochemical values, total protein, globulin, BUN, cholesterol and test-osterone were reduced but total bilirubin and albumin/globulin ratio increased. The enzyme activity of alkaline phosphatase was decreased while that of alanine aminotransferase was elevated. Relative organ weights of thymus, seminal vesicle/prostate and testes were dose-dependently reduced but those of liver and left adrenal gland increased with dose dependency. As for pathological findings, atrophy of thymus, seminal vesicle/prostate and testes and submucosal edema and ulceration in stomach and depletion of lymphocytes in thymus cortex were observed. In conclusion, these clinical, hematological, blood biochemical and patholgical parameters obtained in the present studies can be used for diagnosis of DON-mycotoxicosis, especially, low WBC, platelets, protein, BUN and testosterone and delayed prothrombin time can be available as for reliable diagnostic parameters.

클라인펠터 증후군은 다양한 임상양상을 나타내는 유전질환으로 알려져 있다. 그 중 드물게 경련과 같은 신경학적 증상을 동반하는 경우가 보고되고 있으며 보통 1세 이후의 연령에서 발병하며 항경련제에 반응이 좋은 것으로 알려져 있다. 5개월 남아가 얼굴 찡그림과 딸꾹질을 주소로 내원하였다. 환아는 출생 시 시행한 검사에서 클라인 펠터 증후군으로 진단된 병력이 있었으며 생후 26일에 안구편위로 입원치료의 병력이 있었다. 내원하여 시행한 혈액검사에서 특이소견 없었으나 혈중 테스토스테론 수치가 감소되어 있었고 항뮬러관 호르몬 수치가 증가되어 있었다. 시행한 영상검사에서 정상이었으나 경련이 재발하여 항경련제 복용하기 시작하였으나 간헐적인 경련이 반복되며 난치성 경과를 보이고 있다. 따라서 클라인펠터 증후군 환아에서 경련과 같은 신경학적 증상이 동반될 수 있음을 인지하고 면밀한 검사를 통해 조기에 진단하여 환아의 예후를 향상 시켜야 할 것이다. 이에 저자들은 클라인펠터 증후군으로 진단된 영아에서, 비발열성 난치성 경과를 보이는 1예를 경험하였기에 보고하는 바이다.
