[Metabolism of 99mTc-ethyl cysteinate dimer (99mTc-ECD) in blood--mainly in vitro].

Metabolism of 99mTc-ethyl cysteinate dimer (99mTc-ECD) in blood was studied mainly in vitro. When 99mTc-ECD was mixed with blood taken from 12 subjects, the octanol extraction ratio of ECD (y) decreased rapidly and the octanol extraction ratio-time profile well fitted a monoexponential curve (y = Ae-kt/1000, A, k: constant, t: time after mixing). The k value and hematocrit (Ht) were significantly correlated (k = 0.376Ht-3.27, r = 0.897, p less than 0.001), therefore, it was suggested that the majority of the enzyme which dissolves ECD exists in red blood cells. When ECD was mixed with blood, there were more hydrophilic products of ECD in plasma than those generated by the enzyme in plasma. In vivo input function of 99mTc-ECD was calculated by arterial blood sampling and octanol extraction. The duration of effective input was relatively short, which was attributed to rapid decrease of octanol extraction ratio in vivo.

[67Ga scintigraphic study of a case of recurrent extra-abdominal desmoid tumor].

A case of extra-abdominal desmoid tumor was studied with 67Ga scintigraphy. Extra-abdominal desmoid tumors show an aggressive clinical course with tendency of recurrence in high percentage. On 67Ga scintigraphy, our case revealed a hot spot which is useful of recurrence. 67Ga scintigraphic study was useful in searching for local and recurrence after surgery.

[Clinical evaluation of serum CEA levels in uterine cervix cancer].

Serum CEA levels were measured in the blood of 98 patients with uterine cervix cancer before, during, and after treatment to investigate the relationship among the CEA level, the extent of the disease, and recovery. The CEA level rose as the disease progressed. Although there was no significant difference in the survival rates of patients with various CEA levels, those who returned to normal levels after treatment recuperated better. There was not clear evidence that CEA levels are clinically significant. However, it can be concluded that CEA levels at pre- and post-treatment times are helpful in the early detection of disease, prognosis, and in predicting recurrence or metastasis.
