哈萨克斯坦共和国的学者用活性炭做为肠道吸附剂内服，对实验动物和人的铅中毒进行治疗观察取得了可喜的结果。染醋酸铅动物治疗后症状消失，血和尿中铅的浓度、尿中粪卟啉含量、网织红细球等均比对照组减少；慢性铅中毒病人治疗后自觉症状明显改善，血铅、尿铅、尿δ－ＡＬＡ、尿粪卟啉等指标明显好转。肠吸附剂治疗铅中毒的机理在于吸附胃肠道中的铅，阻断肠壁对铅的重吸收；吸附肠道中的胆汁酸，促进肝内胆汁酸的生成，激活肝脏混合功能氧化酶。
Scholars in the Republic of Kazakhstan used activated carbon as an intestinal adsorbent for oral administration, and observed promising results in the treatment of lead poisoning in laboratory animals and humans. The symptoms of lead acetate-treated animals disappeared, the concentration of lead in blood and urine, the content of urinary fecal porphyrin and reticulocytes decreased compared with the control group. The symptoms of chronic lead poisoning patients were significantly improved after treatment, blood lead and urine Lead, urine δ-ALA, urine coproporphyrin and other indicators significantly improved. The mechanism of gut adsorbent in treating lead poisoning is to adsorb the lead in the gastrointestinal tract and block the reabsorption of lead in the gut wall; to adsorb the bile acid in the intestinal tract, to promote the production of bile acid in the liver, and to activate the liver mixed-function oxidase.
