Figure 5From: Evaluation of drug-induced tissue injury by measuring alanine aminotransferase (ALT) activity in silkworm hemolymph ALT activity in the silkworm hemolymph injected with N -nitroso-fenfluramine and D -galactosamine. Silkworms fasted 6 h were injected with N-nitroso-fenfluramine (A), and with injected D-galactosamine (B), and 1 d later the silkworm hemolymph was collected to measure ALT activity. **P < 0.01 and ***P < 0.001 vs. negative control.
