In the current study, we conducted a study to examine HRCT changes in patients who recovered from the acute phase of SARS at days 60 and 90, and measured the associated inflammatory profiles directly by examining bronchoalveolar lavage fluid (BALF). At 60 days, compared to normal subjects, there was a significant increase in total cell counts in BAL fluid from SARS patients (Table 3 ) with a significant increase in alveolar macrophages (AM) and lymphocytes., The proportion of CD8+ T cells was increased to a greater extent than CD4+ T cells, leading to a significant decrease in CD4/CD8 ratio (Table 4 ). Coronavirus infected cells were not detected in any of SARS patients with low HRCT score or in normal subjects (Table 1) .	./cache/cord-320788-ln8ddyuj.txt	./txt/cord-320788-ln8ddyuj.txt
