Fig. 3: Pathological effects of tail intravenous injection of hydroxy-octadecenoic acids on mouse.

a, b thorax anatomic photos of the DMSO control and the hydroxy-octadecenoic acids-treated group (100 mg kg−1 body mass), respectively. c–e Lung tissue microscopic sections (Bar, 10 µm) of normal control, DMSO control and the hydroxy-octadecenoic acids-treated group, respectively. DMSO control received the same dose of DMSO as the hydroxy-octadecenoic acids-treated group. Hydroxy-octadecenoic acids is an isomeric mixture of 11-hydroxy-9E-octadecenoic acid, 12-hydroxy-10E-octadecenoic acid and 12-hydroxy-10Z-octadecenoic acid obtained from the kernel cake of Jatropha.
