    Notes: Summary Rats fed on a diet containing 0.25% DL-ethionine (ethionine), which has been usually used as carcinogenic dose, demonstrated the early elevations of serum alpha-fetoprotein (AFP) approximately in week 6 of the feeding. After declining once between week 10 and week 14, the serum AFP levels increased again in week 22 of the continuous feeding, when well differentiated hepatocellular carcinoma had already developed. The level of serum AFP after development of hepatoma was found to be lower than those seen during the early elevation of AFP. Furthermore, in ethionine-induced hepatoma-bearing rats, AFP levels in the tumors were rather low as compared to those in the non-tumorous portions of the liver surrounding the tumors. The results indicate that ethionine-induced hepatocellular carcinoma is not an AFP-highly-producing tumor.

    Neuroradiological manifestations of suprasellar pituitary adenomas, meningiomas and craniopharyngiomas (1981)
    Springer

    Notes: Summary The radiological manifestations of 16 pituitary adenomas, six meningiomas and 14 craniopharyngiomas were reviewed. The differential diagnosis of these tumors is possible with a few exceptions when skull radiography, CT, angiography and metrizamide cisternography are carefully evaluated. Prolonged injection angiography (PIA) is particularly important for demonstrating the contours of pituitary adenomas and meningiomas. Metrizamide cisternography is indicated when the tumor contours are obscure using PIA, or when the differential diagnosis is uncertain.
