This results in the buildup of porphobilinogen and aminolevulinic acid.

这会造成大量卟胆原和氨基乙酰丙酸累积。

Furthermore, it causes the buildup of the earlier metabolites like porphobilinogen and aminolevulinic acid, which can be toxic to the body.

这会进一步导致大量生成早期代谢产物，比如卟胆原、氨基乙酰丙酸，对机体有害。

Glucose and heme are the treatments for acute intermittent porphyria as they inhibit aminolevulinic acid synthase, the first enzyme involved in heme synthesis.

葡萄糖和血红素用于治疗急性间歇性卟啉病，他们能抑制氨基乙酰丙酸的合成，即影响参与血红素合成的第一种酶。

Aminolevulinic acid, in particular, is the most likely culprit since it could cross the blood brain barrier and affect the central, autonomic, and peripheral nervous systems.

特别是氨基乙酰丙酸，是最可能的“嫌疑犯”，因为它可以跨越血脑屏障，影响中枢、自主和外周神经系统。
