This transitive sense is very rare in everyday English. Avoid using 'gangrene' as a transitive verb ('X gangrened Y') — instead use the natural alternatives shown in the examples: 'cause gangrene in' or 'lead to gangrene in'. The passive form ('was gangrened') is somewhat more common in medical writing than the active, but 'cause gangrene' remains the preferred choice in most contexts.

用法筆記
Like the transitive sense, this intransitive use is extremely rare in spoken and written English. Avoid using 'gangrene' as an intransitive verb ('the tissue gangrened') — instead use the natural alternatives shown in the examples: 'develop gangrene', 'become gangrenous', or 'gangrene sets in'. The intransitive verb is found mainly in older medical textbooks, not in modern everyday usage.
