Aims: To assess the degree of liver fibrosis in the chronic hepatitis patients in comparison with liver biopsy performed at the same time. Methods: We studied 66 consecutive patients with chronic hepatitis, in which liver stiffness was measured by FibroScan and liver biopsy was performed in the same session (assessed according to the Metavir score). Results: FibroScan values ranged from 3.8 to 75 kiloPascal (median, 16.46 kPa). According to the Metavir score of the 66 patients: 22,1% had F0 and F1, 12 had F2, 16.6% had F3 and 43,9% had F4. The mean values of liver stiffness in patients were: F0 & F1: 5.35 ± 2.73 kPa; F2: 8.59 ± 3.37 kPa; F3: 12.45 ± 4.69 kPa; F4: 32.44 ± 18.52 kPa. There were the significant positive correlation between the liver stiffness measured by FibroScan and liver biopsy (r = 0.6, p < 0.05). Conclus...

Considerable economic development is expected in particularly for tourism, navigation and aquaculture. However, in recent years the environmental quality of the Bay has been degraded by human activities and impacts. Even though the conditions of the Bay are monitored with in-situ measurements in a marine station, the environmental data, measured only in half-yearly intervals, are not sufficient for comprehensively assessing environmental quality at various temporal and spatial scales. Therefore, it is necessary to seek for complementary data sources to assess, control and manage the marine environment of Nha Trang Bay. We conducted three field trips in Nha Trang Bay at 23 stations, including 6 off-shore stations that are not influenced by freshwater from land, and measured the distribution of marine optical properties. These properties include the light e...

However, they have been degraded under high pressures of human activities. Combining depth-invariance index and ground-truthing, distribution of seagrass beds in Cam Ranh Bay was identified by analyses of multi-remote sensing images such as LANDSAT, SPOT and ALOS AVNIR-2. Although coverage of seagrass meadows was1178 ha, the seagrass meadows were being degraded by illegal fishing methods, aquaculture and discharges from industries and living domestics. The reducing ratio of seagrass coverage has been increased in recent years. While the depth-invariance index method would help to detect the areas of seagrass beds, this method requires combination of field trip and absorption library methods to increase classification accuracy. Final maps of the status and changes of seagrass beds could help to integrate the sustainable development of economy with protection of natural resources.
