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.

Ligamentum flavum cysts (LFCs) are rare but clinically significant lesions in the lumbar spine. These cysts, often found incidentally, can mimic the symptoms of intervertebral disc herniation and cause radiculopathy. This article details a case involving an 80-year-old woman with severe lower back and radicular pain due to an LFC at the right L5/S1 facet joint that was unresponsive to conservative treatment. Magnetic resonance imaging and neurography confirmed that the cyst compressed the right S1 nerve root. Surgical excision via partial hemilaminectomy resulted in complete symptom relief and nerve decompression. Histopathological analysis identified the cyst as degenerative without a synovial lining. This case underscores the importance of considering LFCs in the differential diagnosis of neurogenic leg pain and highlights the efficacy of surgical excision for symptom resolution and preventing recurrence.

A 44-year-old man, who had a history of myocardial infarction (MI) due to thrombotic occlusion of right coronary artery (RCA) aneurysm, visited emergency department presenting with ST-segment elevation myocardial infarction (STEMI). The patient had been on oral anticoagulant therapy (warfarin) from the first thrombotic event, but the medication had been recently changed to aspirin 4 months before the second event. Emergent coronary angiography revealed thrombotic total occlusion of RCA with heavy thrombotic burden from middle RCA to the ostium of the posterior descending branch. Combination pharmacotherapy was performed with anticoagulants (heparin), fibrinolytics (urokinase), and Glycoprotein IIb/IIIa antagonists (abciximab), in addition to mechanical thrombosuction. However, on hospital day 2, the patient complained recurrent chest pain and again underwent coronary angiography, which revealed distal embolization of large thrombus to the posterior lateral branch. Coronary flow was recovered after repeated mechanical thrombosuction was performed. This case has shown the importance of aggressive combination drug therapy, accompanied by mechanical thrombosuction in patient with myocardial infarction due to thrombotic occlusion of coronary artery aneurysm and the importance of unceasing life-long anticoagulant therapy in those particular patients.

OBJECTIVE: Radiation injury includes radiation necrosis and apoptosis. The purpose of this study is whether steroids and calcium channel blockers are effective for the prevention of single high dose irradiation-induced apoptosis in the rat brain. METHODS: Eighty Sprague-Dawley rats were divided into four experimental groups: Control(nontreated, n=20), Dexamethasone-treated(0.1mg/kg, n=20), Prednisolone-treated(2mg/kg, n=20), Nimodipine-treated (0.5mg/kg, n=20). After drug was administered, the right hemisphere of rat's brain was exposed to a single 10Gy dose of gamma rays using Ir-192. All brains underwent histological examination at 1 week, 2 weeks, 4 weeks, and 8 weeks after irradiation to evaluate cortical thickness and number of apoptotic cells. Apoptotic cells were detected by TUNEL assay. RESULTS: In nimodipine-treated group, apoptotic cell count was reduced significantly, compared to that of control(non treated) group at 4 and 8 weeks after irradiation(p<0.05). The decrease of cortical thickness was reduced significantly in nimodipine-treated group, compared to that of control group(p<0.05). There was no significant changes in the number of apoptotic cells and cortical thickness in prednisolone and dexamethasone-treated groups compared with those of control. CONCLUSION: These results suggest that nimodipine treatment may have effects on the prevention of radiation-induced apoptosis. If it could be established that calcium channel blockers inhibit radiation injury, they might be useful in radiation therapy. Further investigation of calcium channel blockers including dosage effectiveness, intracellular calcium ion concentration and effects on tumor tissue are necessary to clarify the usefulness of nimodipine.

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.
