SFTPD and malaria: The mean levels of SP-D in the plasma were significantly elevated in the malaria-infected mice with ALI/ARDS (24.79 ± 0.23 ng/mL) compared with those in the malaria-infected mice in the non-ALI/ARDS group (6.24 ± 0.69 ng/mL) and the mice in the control group (5.86 ± 0.64 ng/mL) (p = 0.009).
