These study was designed to observe the appearance and the characteristics of apoptotic cells during the development of knee joint in rat. The fetus were collected on the 16th, 17th, 18th, 19th, and 20th day of pregnancy. In this study, TUNEL staining, electron microscopic investigation and immunocytochemical gold labeling techniques were used. In the immuno-cytochemical gold labeling techniques, primary antibodies were used, which were to be polyclonal rabbit anti-mouse/ rat Bax, polyclonal rabbit anti-tissue transglutaminase C, and polyclonal goat anti-cpp32p20. The samples were observed under JEOL 1200 EX-II transmission electron microscope. The results were as follows. 1. In a 16-day-old fetus, between femur and tibia cartilages, mesenchymal cells were observed. Mesenchymal cells had marginated heterochromatin and dilated rough endoplasmic reticulum. 2. In a 17-day-old fetus, the knee joint clefts were first formed. In the primordial cruciate ligaments between the cartilages, capillaries were scattered. The apoptotic cells, which had fragmented and condensed nucleus, showed in the synovium. And necrotic cells, which had nuclear chromatin margination, perinuclear cisternae, and dilated rough endoplasmic reticulum, also were observed in the joint cleft surface. 3. From the 18-day-old fetus, phagocytic synovial cells and secretory synovial cells could be confirmed. The apoptotic cells were not seen. 4. In a 17-day-old fetus, a few cells were positive for TUNEL reaction in the joint cleft region. 5. In a 17-day-old fetus, Bax were marked on the mitochondria, endoplasmic reticulum of apoptotic cells. Also, it was marked at the phagocytosed apoptotic bodies in the neighboring cells. 6. In a 17-day-old fetus, the tissue Transglutaminase C were marked in the perinuclear region, vacuoles, cell membrane and extracellular matrix of the apoptotic cells. Also, it was marked at the phagocytosed apoptotic bodies in the neighboring cells. 7. In a 17-days-old fetus, CPP32 labeling were marked in the cytoplasm of the apoptotic cells. Practically, it was distributed between the phagocytosed apoptotic bodies and the neighboring cells. On the basis of above findings, it is obvious that the joint cleft are first formed in a 17-day-old fetus, a few cells are to be TUNEL positive signals, and the apoptotic cells contain Bax, tissue Transglutaminase C, and CPP32. Therefore the apoptotic cells and the necrotic cells are appeared in the 17-day-old fetus, and these cells are concerned with joint cleft formation.

BACKGROUND: We investigated the association between socioeconomic status and adherence to health check-ups in a Korean population aged 40 years or older. METHODS: This cross-sectional study included 12,311 participants who participated in the 2010–2012 Korean National Health and Nutrition Examination Survey. Self-reported questionnaires were used to assess each participant's socioeconomic status (household income, occupation, and education) and adherence to health check-ups. RESULTS: Men with a higher income (highest vs. lowest: odds ratio [OR], 1.799; 95% confidence interval [CI], 1.296–2.497) and men with a higher education level (≥12 vs. < 6 years: OR, 1.488; 95% CI, 1.078–2.054) and office workers compared with manual workers (men: OR, 1.431; 95% CI, 1.077–1.902; women: OR, 1.783; 95% CI, 1.256–2.532) appeared to undergo more health check-ups. In particular, men and women with a higher income and education appeared more likely to undergo opportunistic health check-ups (men: highest vs. lowest income: OR, 2.380; 95% CI, 1.218–4.653; ≥12 vs. < 6 years education: OR, 2.121; 95% CI, 1.142–3.936; women: highest vs. lowest income: OR, 4.042; 95% CI, 2.239–7.297; ≥12 vs. < 6 years education: OR, 2.475; 95% CI, 1.283–4.775). CONCLUSION: A higher socioeconomic status was associated with a higher rate of participation in health check-ups. More efforts are needed to identify the factors associated with disparity in adherence to health check-ups.

The supranuclear control of eye movement invo l ves the pathway extending from the cerebral cortex to theocular motor nuclei located in the brain stem. This paper de-scribes the normal supranuclear pathway, whichcontrols eye movement. We also include magnetic resonance imaging findings of the typical ocular manifestationscaused by disorders involving the supranuclear pathway, providing the anatomic ex-planations for certain clinicalsigns.

BACKGROUND: The purpose of this study was to investigate the differences in health behaviors and dietary habits between the metabolically healthy group and the metabolically abnormal group in overweight and obese subjects based on the data of National Health and Nutrition Survey (NHANES). METHODS: Using the NHANES data (2007–2010), a total of 18,188 subjects were grouped into the metabolically healthy group and the abnormal group using the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) definition. Then we compared their health behaviors, dietary behaviors and nutrient intakes after adjustment for variables in overweight and obese groups. RESULTS: The proportion of metabolic abnormalities tended to increase with increasing age in both overweight and obesity groups.(P for trend <0.001) After adjusting various confounding variables, the odds ratio (95% confidence interval) of skipping any meal and breakfast for metabolically abnormality were 1.318 (1.066–1.631) and 1.354 (1.076–1.705) in male obese group and those of skipping breakfast and carbonated drink intake were 1.578 (1.168–2.133) and 1.540 (1.188–2.492) in female obese group. Daily potassium intake (P=0.032) and daily vitamin C intake (P=0.048) in the male overweight group and daily water intake (P=0.046) and daily carbohydrate intake (P=0.038) in the female overweight group were associated with metabolically abnormality. CONCLUSIONS: There were differences in health behaviors and nutrient intake according to metabolically abnormality in overweight and obese groups.

PURPOSE: To evaluate the effects of an intravitreal amniotic membrane (AM) injection on a rat model of laser-induced choroidal neovascularization (CNV). METHODS: Intravitreal injection of AM (12.5 microgram/mL) into the left eyes and phosphate-buffered saline into the fellow eyes of 15 rats was performed immediately after laser injury. At week 2, after angiography, the rats were sacrificed, and histopathologic analysis was performed. Angiographic and histopathologic assessments of the effects of AM injection on CNV growth were compared between the two groups. RESULTS: CNV thickness was found to have increased more in the AM treatment group (141.54+/-8.12 micrometer) than in the experimental control group (65.23+/-16.90 micrometer) (p=0.010). CONCLUSIONS: Intravitreal AM injection demonstrated histopathologic pro-angiogenic properties in a rat model of CNV.

Cerebral malalria is a life-threatening complication of Plasmodium falciparum infection. RBC exchange transfusion (RCE) can reduce the burden of parasitemia in this situation. We have experienced two cases of cerebral malaria treated with automated RBC exchange as an adjunct to standard chemotherapy. Case 1: A 42-year-old male was referred to the emergency room with a history of 3 days of fever after having returned from Congo. Peripheral blood smear showed the P. falciparum parasitemia of 70-80%. Quinidine and doxycycline were administered but, mental state started to deteriorate. He underwent RCE on hospital day 2 to reduce the parasitemia to 10% after 8 hours. No parasite could be found on day 3 after the RCE. Case 2: A 62-year-old male was referred to the emergency room with a history of 3 days of fever after having returned from Cameroon. P. falciparum parasitemia was 10% on peripheral blood smear. Quinidine and doxycycline were immediately started but headache developed abruptly and he underwent RCE on hospital day 3. After 8 hours following the completion of RCE, parasitemia decreased to less than 1%. Automated RBC exchange transfusion can rapidly reduce the burden of parasitemia and achieve improvement of neurologic symptom and sign in patients with cerebral malaria.

Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery.
