药媒—2000在青霉素发酵生产上的应用

药媒－2000作为微生物发酵的一种新型氮源，我们首次在青霉素发酵生产上应用，通过实验结果分析表明，利用药媒－2000作为青霉素发酵生产上的补充氮源，其发酵水平优于其它氮源。     

Abdominal aortic aneurysm and renal hamartoma in an infant with tuberous sclerosis.

A case is presented of an infant with tuberous sclerosis admitted with status epilepticus. When the seizures were controlled, it was found that the child was hypertensive. A large renal tumor and an abdominal aortic aneurysm was found during the hypertensive evaluation. She underwent abdominal aortic aneurysm resection and radical nephrectomy, and vascular continuity was re-established sucessfully with a Dacron prosthesis. The technique is illustrated. The reconstruction is patent one year following reconstruction. The etiology of the aneurysm is discussed.
