In the course of this program, we have encoun tered some questions which you may be able to answer. Telfer's experience with the use of BAL (British Anti-Lewisite), in the treatment of lead poisoning seems to Indicate that t^is substance acted to delead the patient. Have you had any personal experience with the use of BAL in the treatment of7lead poisoning, either acute or chronic? Would you recommend its use or would you advise physicians to treat oases of lead poisoning by more orthodox methods such as the use of a high calcium diet and Vitamin D? What laboratory procedures would you advise the general practitioner, who does not she a great deal of lead poisoning, to perform in order to help establish a diagnosis? What in your opinion are significant variations from the normal in urinary lead, percentage: of stippled red cells, and basophilic aggregations? I hope that as a result of your wide experience that you can assist us in formulating answers to these questions. Sincerely yours Chief, Bureau of Adult Health N21258
