Myelin packing is affected by acute H2S exposure. (A) Under control conditions, myelin was well-developed, with a compact structure with axons enclosed in myelin visible (indicated by the arrows), and the layers exhibited a highly organized appearance. (B,C) In the H2S-exposed group, many small vacuoles (not quantified) were observed in the myelin at 24 h, 48 h, and 72 h (asterisks). In (C), myelin exhibited a loose structure and an increased inter-layer gap with visible stratification, which indicated a disrupted development (thin arrows).
