The technique for solubilization of various filter samples into a liquid scintillator has been established to overwhelm the inherent shortcomings of a disc counting technique. Conventional liquid scintillation measurement methods that employ the quenching correction methods can be adopted to the homogeneously dispersed filter samples, which consequently enable the activity of the filter samples to be determined.
This technique involves a resolution of the last problem in a sample preparation technique.

In order to know in detail the distribution, absorption and excretion of putrescine (1, 4-diaminobutane), after a single subcutaneous injection of 14C-
putrescine (carrier free) in mice, localization of radioactivity in various tissues was followed by whole-body autoradiography and changes in radioactivity levels in blood, various tissues, expiration, urine and feces were examined.
During 6 hours after injection, 22.5±3.2% of radioactivity was excreted in the urine, and after that the percentage excretion increased only slightly.
The percentage of fecal excretion was small, being 2.7±0.2% during 5 days after injection.
A considerable amount of putrescine was rapidly degraded to 14CO
2;
during 2 hours 34.4±4.9% of radioactivity was expired as 14CO
2.
In the studies on distribution in the tissues, at 10 minutes after injection, the highest radioactivity per g wet tissue was found in the kidney, but the radioactivity decreased rapidly. At 10 minutes after injection, the next highest distribution was found in the intestine. The high radioactivity in the intestine was detected also at 1 hour and 24 hours. The radioactivity in the pancreas was highest at 1 hour and 24 hours. A high radioactivity was also detected in the bone marrow by autoradiography.
Therefore, the present study suggests that the accumulation of putrescine in mice take place mainly in the pancreas, bone marrow, intestine and liver.

Recently galactosyltransferase has been noted as a new tumor marker. In this report galactosyltransferase activity was measured in sera of various diseases including malignant tumors and the levels of the enzyme activities were compared. The levels of the enzyme were higher in sera of malignant tumors and liver diseases than those in sera of other diseases. In malignant tumors little organ specificity was found with respect to the levels of galactosyltransferase activities. The levels of the enzyme were considered to have no relation to carcinoembryonic antigen or a feto protein. On the other hand, in liver diseases the levels of the enzyme were correlated to the severity of liver damage. Therefore, it is reasonable to presume that the elevation of serum galactosyltransferase activity is caused chiefly by malignant tumors and liver damage.

The elution of the neutron activated elements out of hair soaked in some organic solvents and EDTA solution was studied. Soakage of the hair sample, which was washed with water and acetone in advance as IAEA's proposal, in ether and acetone for 30 minutes each resulted in no elution of Hg, Zn, Co
and Se.
Elution of Zn
and Co
from the powdered hair sample soaked in 0.1 M EDTA solution was rapid, while Zn
did not elute out from the cut hair (2-3 mm length) on the same condition.
Hg, Se
and Au
were not eluted out by 0.1 M EDTA solution in the both case of cut hair and of powdered hair.
Br
was removed by 0.1 M EDTA solution from the cut hair and from the powdered hair with equal ease.
