Familial Idiopathic Thrombocytopenic Purpura

Abstract

Closer examination of the inside of the tube, however, revealed the remains of the original large blister and two smaller blisters.Another section of the tube was half cut across at one of the light patches.Two layers of the tube were clearly discernible, one on each side of the metal reinforcement (see 'Fig.).These layers could be separated quite readily, and it was found that the inner layer would swell very con- siderably if trichlorethylene were applied to it.The swelling continued until the entire lumen of the tube was obstructed.When fresh air was blown through the tube the process was shown to be reversible and the swelling almost entirely disappeared.
