OBJECTIVES: The aim of this study was to investigate the influences of affect states and mood congruent/incongruent variables in psychosis-proneness. METHODS: Five hundred and two undergraduate students completed the SPQ and other scales. Psychosis-proneness was measured by Schizotypal Personality Questionnaire (SPQ), and affect states were measured by Positive Affect and Negative Affect Schedule (PANAS). Mood congruent variables were measured by Mood reactivity in Mood Survey and Affect Intensity Measure (AIM), and mood incongruent variables were measured by Trait Meta-Mood Scale (TMMS), Emotional Inhibition and Aggression Control in Emotional Control Questionnaire (ECQ). RESULTS: By hierachical regression analysis, total 39.1% of SPQ total score variance was explained by emotion related variables. In detail, negative and positive affect states explained 26% of variance, and affect intensity and mood reactivity of mood-congruent variables added 7.7% and mood aware, emotional inhibition & aggression control among mood-incongruent variables added 5.5%. And emotion related variables explained 43.8% of negative symptom, 27.6% of positive symptom and 23.6% of disorganization score. CONCLUSION: Negative affect was revealed as important factor for psychosis-proneness, and positive affect acted as the reversed role. Mood reactivity and affect intensity acted as mood congruent variables which amplified and reinforced the influence of negative affect on psychosis-proneness. Mood aware, repair and aggression control acted as mood incongruent variables which modulated and reduce the influence of negative affect, while mood attention and emotional inhibition acted as mood congruent variables in contrast with the prediction.

Objective: Precise knowledge regarding the mechanical stress applied to the intervertebral disc following each individual spine motion enables physicians and patients to understand how people with discogenic back pain should be guided in their exercises and which spine motions to specifically avoid. We created an intervertebral disc degeneration model and conducted a finite element (FE) analysis of loaded stresses following each spinal posture or motion. Methods: A 3-dimensional FE model of intervertebral disc degeneration at L4–5 was constructed. The intervertebral disc degeneration model was created according to the modified Dallas discogram scale. The von Mises stress and range of motion (ROM) regarding the intervertebral discs and the endplates were analyzed. Results: We observed that mechanical stresses loaded onto the intervertebral discs were similar during flexion, extension, and lateral bending, which were greater than those occurring during torsion. Based on the comparison among the grades divided by the modified Dallas discogram scale, the mechanical stress during extension was greater in grades 3–5 than it was during the others. During extension, the mechanical stress loaded onto the intervertebral disc and endplate was greatest in the posterior portion. Mechanical stresses loaded onto the intervertebral disc were greater in grades 3–5 compared to those in grades 0–2. Conclusion Our findings suggest that it might be beneficial for patients experiencing discogenic back pain to maintain a neutral posture in their lumbar spine when engaging in daily activities and exercises, especially those suffering from significant intravertebral disc degeneration.

OBJECTIVE: The present study was conducted to evaluate the viability of germ cells form the adult and fetal ovarian tissues after vitrification followed by xenografting. METHOD: The human adult ovarian tissues were obtained from 33 years old patients, and the fetal ovarian tissues were obtained from 22 weeks and 25 weeks in gestation. ovarian tissues were cryopreserved by vitrification with 5.5 M ethylene glycol (EG 5.5) and 1.0 M sucrose as cryoprotectants. Adult and fetal ovarian tissues were pre-equilivrated with EG 5.5 at room temperature for 10 and 5 minutes, respectively and plunged into liquid nitrogen immediately. Frozen-thawed tissues were xenografted into NOD-SCID mice to evaluated the viability and capacity for further growth of the primordial follicles. Grafts were recovered from the recipients 4 weeks after transplantation and histological analysis was accomplished. RESULT AND CONCLUSION: Grafts recovered 4 weeks after transplantation contained less number of oocytes and primordial follicles compared to that of the fresh tissues. Survived follicles were mainly primordial and intermediary with larger diameter and more granulosa cells. It is confirmed that 1) the ovarian tissues were healthy and the germ cells were survived after vitrification, and 2) the survived fetal primordial follicles after vitrification resumed the growth in the xenofrafts.

OBJECTIVE: The aim of this study was to investigate the relationship between emotional traits and schizotypal symptoms and to establish a hypothetical model for the causal relationship between them. METHODS: Schizotypal symptoms were assessed using the Schizotypal Personality Questionnaire (SPQ), and a total of seven emotional traits considered to be potential risk factors for schizotypy were categorized as emotional disturbances, emotional attenuators or emotional amplifiers. A total of 502 undergraduate students completed the SPQ and other scales. RESULTS: The result of the present study suggested that the high levels of emotional disturbance in individuals who are prone to schizotypy or psychosis are amplified by their intensity and fluctuation. However, if their emotion attenuating abilities function well, these disturbances can be controlled and the schizotypal symptoms and progression to psychosis can be contained. Discriminant analysis showed that 69.0% of the subjects with many schizotypal symptoms and 80.7% of the subjects with few schizotypal symptoms were correctly classified. CONCLUSION: The present study suggests the possibility of using emotional traits to identify the risk factors for psychosis.

BACKGROUND: A predominant accumulation of adipose tissue in abdominal region confers increased risk of cardiovascular disease. The best technology available for measurement of regional fat distribution is computed tomography. However, computed tomography is limited its use for clinical purposes by cost. The aim of this study is to identify the best simple anthropometric index of abdominal visceral fat accumulation. METHODS: To quantify the relationship between anthropometric indices of abdominal obesity(waist circumference, waist to hip ratio, waist to height ratio, body mass index, abdominal sagittal diameter) and abdominal(total, visceral, subcutaneous) fat areas measured by computed tomography, correlation and multiple regression analyses have been conducted. RESULTS: No significant difference for waist circumference, body mass index and sagittal diameter between men and women have been found. Mean value of waist to hip ratio is larger in women, but waist to height ratio is larger in men. The mean abdominal total fat area and mean subcutaneous fat area are higher in women. Interestingly, men, despite lower total fat area, have higher mean abdominal visceral area. Thus, the mean visceral fat to subcutaneous fat ratio is much higher in men. Abdominal sagittal diameter shows the highest correlation(men: 0.69, women: 0.76) with abdominal visceral fat area in both genders. Stepwise regression analyses have been performed to determine the best simple anthropometric index of abdominal visceral fat accumulation. In men, the significant indices are abdominal sagittal diameter, body mass index, and waist to height ratio. In women, abdominal sagittal diameter is the only significant index. CONCLUSION: Abdominal sagittal diameter, in comparison with the waist circumference, waist to hip ratio, waist to height ratio and body mass index, is the best predictor of the amount of abdominal visceral fat.

Isolated ACTH deficiency is a rare cause of secondary adrenocortical insufficiency. The clinical presentation can be similar to that of primary adrenal insufficiency, but most of them may be nonspecific. A female patient of 25 months of age, complainig short stature, showed hypocortisolemia without ACTH & cortisol stimulation by insulin-induced hypoglycemia test. All the other hormone state was normal. Left hand AP view revealed delayed bone age(3 month) compared with chronological age. No radiologic abnormality was found in sella MRI and adrenal CT. Here we report a case of isolated ACTH deficiency presented by short stature.
