In presenting some patients with spine cord diseases detected by MR imaging in Huu Nghi Hospital, the author leads to remark that MRI has advantages in diagnosis of congenital malformations, degenerative diseases, syringomyelia and neoplasia of the spine and spinal cord. MRI indications for spine examination are suggested in conclusion.

36 patients with age of 15-63 found the cerobrovascular pathology during 2/1997-2/1998 in friendship hospital by the cerebrovascular angiography. Methods: analysis of cerebral parenchyma to find the empty focus of sign and abnormal focus, taking the vascular photograph and analysis of the cerebrovasular by resetting as MIP program comparing with the images of CT scanner, image of DSA technique (4 patients) and results of operation (6 patients). The results have shown that the comparison of the operation (6 patients) with the angiography as technique DSA found that the MRI were suitable with the arteries with diameter of 5 mm and the abnormality of the vascular. The MRI of the cerebral parenchyma give the images which was more obviously than these of CT. scanner

Aims: The objective of the study was to isolate bacteriophages and conduct a comprehensive analysis of their potential against Xanthomonas oryzae pv. oryzae (Xoo) strains in the Mekong Delta, Vietnam. Methodology and results: Twelve Xoo strains were isolated from rice fields located in the Mekong Delta, Vietnam. Among these strains, three strains Xoo L019, L020 and L024, showed the highest disease index of bacterial blight. Four phages specific to Xoo were isolated from soil, water and leaf samples, and their morphologies were determined. In a test against 12 Xoo strains, phage L541, MLA23 or W41 could infect 10 of the 12 Xoo strains, while phage LBH01 could infect 8 of the 12 Xoo strains. The stability of the phages to pH, organic solvents, UV-A and UV-B was also evaluated. Conclusion, significance and impact of study The initial characterization of the phages indicates their potential as biocontrol agents against bacterial blight in rice. The study is one of the very first studies about Xoo phages in rice in Vietnam.
