However, due to global nature and the long term sustainability of this shipbuilding industry, an investigation of competitiveness in terms of global standard is of prime importance. This paper focuses on studying some crucial competitive factors like labor skill, labor availability, labor man-hour, labor cost ＆ productivity for local shipbuilding in Bangladesh. The analysis also focuses on existing access to the resources like materials, knowledge and capital which are equally important factors for the expansion of shipbuilding. Comparison of these parameters with other nations have been made qualitatively and quantitatively to find the level of our shipbuilding. On the basis of existing condition and future vision, some recommendations have been made which might be useful for accelerating the development of this sector.展开更多

METHODS:Concentrations of MCP-1,soluble adhesion molecules intercellular adhesion molecule-1 (sICAM-1),sP- selectin,interleukin (IL) 6,and IL10 in serum were estimated in the group of 40 patients with chronic hepatitis C treated with IFNalpha2 b and RBV in 0,16,32,48 wk of the therapy, RESULTS:In chronic hepatitis C,before and during the treatment,the serum levels of MCP-1 and sP-selectin in responders were similar to those of healthy subjects.In non- responders (NR),MCP-1 increased in the course of IFNc^+RBV treatment,differences were statistically significant as compared to responders.MCP-1 correlated statistically with the activity of periportal inflammation (r=0.35,P<0.05) but not with staging of liver fibrosis,sICAM-1 positively correlated with inflammatory activity and fibrosis in NR.sP-selectin did not correlate with histological findings in the liver.The MCP-1 correlated with the soluble form of sP-selectin concentrations (r= 6,P<0.001) and with IL-10 level in NR (r=0.4,P<0.05).There was no correlation observed between the concentration of MCP-1 and sICAM-1,IL-6 during the treatment. CONCLUSION:MCP-1 concentration may be a prognostic marker of the efficacy of IFN+RBV therapy in patients with chronic hepatitis C.展开更多
