| 1 | Morphological and biochemical responses of Oryza sativa L.(cultivar MR219) to ion beam irradiation显示文摘Objective: Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation. Methods: In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation. Results: The study demonstrated that low doses(10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam(10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples. Conclusions: Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics. | Anna Pick Kiong LING Ying Chian UNG Sobri HUSSEIN Abdul Rahim HARUN Atsushi TANAKA Hase YOSHIHIRO | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，12： | 5 |
| 2 | Gastrointestinal sarcoidosis associated with pneumatosis cystoides intestinalis显示文摘A 39-year-old male reported fevers,weight loss,watery loose stools,and decreased visual acuity in his right eye over the prior five years.He was pancytopenic,had an elevated American council on exercise level,total bilirubin,and alkaline phosphatase.Computed tomography revealed massive hepatosplenomegaly and emphysematous lung changes.Liver biopsy showed non caseating granulomas.The patient was diagnosed with extrapulmonary sarcoidosis and was treated with prednisone.The patient symptomatically improved but 5 mo later presented with abdominal pain caused by perforation of the cecum.He underwent a cecectomy and pathology revealed pneumatosis cystoides intestinalis.This represents the first reported association between pneumatosis cystoides intestinalis and sarcoidosis.The etiology of pneumatosis cystoides intestinalis in this case was likely multifactorial and involved both effects of the corticosteroids as well as the advanced nature of the gastrointestinal sarcoidosis.Furthermore this case has the unique features of emphysematous lung changes and pancytopenia which are uncommon with sarcoidosis. | Hussein Rahim Mubashir Khan Jay Hudgins Kevin Lee Lei Du Louis Amorosa | 2013 | World Journal of Gastroenterology2013，19，7： | 3 |
