  • Rotting bacteria were isolated from decayed root rot of ginseng (Panax ginseng C.A. Meyer), cultured purely, and it's pathogenicity was confirmed by reinoculation test. Two strains (E3, E7) were selected to be tested in more detailed study with respect to their morphological, cutural and biochemical characters. The strains causing red rot of ginsneg were identified as Erwinia carotovora.

  • Idiopathic external root resorption is an apparently infrequently occurrence involving single or multiple teeth. Presented is an unusual case of multiple external root resorption associated with craniopharyngioma. Although the cause of this resorption was not determined, several possibilities are discussed. The literature to a systemic etiology for external root resorption is briefly reviewed.

  • Long-term posttreatment stability is great concern to all orthodontist. So, this article was disussed that etiology of relapse, classificatioan of retention, duration of retention and treat after relapse. The most important thing about stability was considered that growth pattern, periodontal remodeling, neuromuscular factors and applied the appropriate mechanotherapy. Retenton was considered during the treatment planning and required considerable analytic thought.

  • A 3-year-old male Maltese dog(weighing 2.5 kg) was referred with an excessive movement of mandible and depression. Comprehensive diagnostic investigation revealed an end-stage of renal disease with secondary hyperparathyroidism. The renal allograft was performed after the condition of dog was stabilized by hemodialysis and medical treatment. After transplantation, the renal function of this dog was returned to normal. thereafter, the dog died suddenly without apparent clinical signs. The subsequent pathological studies revealed the actual etiology of death was not clearly identified However acute pancreatitis caused by abrupt introduction of food after prolonged luting might be involved in the etiology. This case study showed the necessity of pancreatic function test in postoperative management after renal transplantation.

  • Purpose: The purpose of this study was to investigate the Quality of Life (QOL) and related factors in the patients with dizziness. Methods: The data were collected between March and June 2008 for 200 individuals who agreed to participate in the study. Uncertainty (Uncertainty in illness scale), anxiety, depression (Hospital anxiety & depression scale) and Vestibular disability activities of daily living (Vestibular disability-activities of daily living [ADL] scale) as well as QOL (Dizziness Handicap Inventory) were measured. Results: The mean QOL score was 37.5 (${\pm}23.0$). Monthly income, etiology of, frequency of, and total duration of dizziness were the significant factors related to QOL in these patients. Having had a fall, anxiety, depression, uncertainty and vestibular disability in daily living were also significant factors influencing QOL. In multiple regression analysis, anxiety, vestibular disability-ADL, falls, total duration of symptoms, uncertainty, and etiology of dizziness explained 41% of variance of QOL. Conclusion: The level of QOL in our patients was moderate as compared to those in previous studies. Anxiety and vestibular disability were the most important factors predicting low QOL. Use of nursing intervention programs designed to relieve these factors should also result in improving the QOL in the patients with dizziness.

  • Purpose: Respiratory morbidity is the most common problem among neonates admitted to neonatal intensive care units. Therefore, the aim of this study was to make a differential diagnosis between transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), and pneumonia through comparison of clinical features and test results. Methods: This retrospective study was conducted in 86 infants with TTN, RDS, or pneumonia. These were infants who had respiratory distress, were born after ${\geq}34$ weeks of gestation, and transferred to the neonatal intensive care unit of Kosin University Gospel Hospital between June 1, 2011 and June 30, 2016. Results: The numbers (percentage) of infants with TTN, RDS, and pneumonia were 51 (59.3%), 20 (23.3%), and 15 (17.4%), respectively. Late-preterm and early-term newborns accounted for 65.1% of the infants. Tachypnea was observed in 74.4% of the neonates. The median age at admission was 4 hours (0 to 116) after birth. The infants with RDS had significantly lower birth weights, pH levels, base excess and oxygen saturation levels at admission, longer duration of total ventilator therapy, and hospital stay than those in the other two groups. The infants with pneumonia showed significantly high initial high-sensitivity C-reactive protein levels and significant chest radiographic findings. Conclusion: Early differential diagnosis for TTN, RDS, and pneumonia is challenging because they show similar respiratory symptoms at an early stage. Clinical features and test results can be used to determine the etiology of respiratory distress and early antibiotic treatment.

  • Complexins play a critical role in the control of fast synchronous neurotransmitter release. They operate by binding to trimeric SNARE complexes consisting of the vesicle protein Synaptobrevin and the plasma membrane proteins Syntaxin and SNAP-25, which are key executors of membrane fusion reactions. SNARE complex binding by Complexins is thought to stabilize and clamp the SNARE complex in a highly fusogenic state, thereby providing a pool of readily releasable synaptic vesicles that can be released quickly and synchronously in response to an action potential and the concomitant increase in intra-synaptic $Ca^{2+}$ levels. Genetic elimination of Complexins from mammalian neurons causes a strong reduction in evoked neurotransmitter release, and altered Complexin expression levels with consequent deficits in synaptic transmission were suggested to contribute to the etiology or pathogenesis of schizophrenia, Huntington's disease, depression, bipolar disorder, Parkinson's disease, Alzheimer's disease, traumatic brain injury, Wernicke's encephalopathy, and fetal alcohol syndrome. In the present review I provide a summary of available data on the role of altered Complexin expression in brain diseases. On aggregate, the available information indicates that altered Complexin expression levels are unlikely to have a causal role in the etiology of the disorders that they have been implicated in, but that they may contribute to the corresponding symptoms.
