Abstract
A new method has been developed for imaging the thyroid gland by the use of 201Tl radioactive implant induced X-ray emission (RIXE). The thyroid phantom was made from two cylindrical tubes embedded in plastic neck phantom. Each tube consisted of stable iodine and 201Tl radioactive source in 10 ml water solution. Some photopeaks in the energy range from 20 to 200 ke V were scanned along a horizontal axis by the collimated Ge detector with high energy resolution. The distribution on the horizontal axis was obtained for the generated I K alpha-ray and some primary 201Tl radiations. The 201Tl RIXE scanning can provide information about the distribution of iodine with 201Tl as well as 201Tl distribution in the thyroid gland. The effectiveness of the 201Tl RIXE technique as a thyroid scanning method is discussed.

Abstract
Using normal rats, retention values and subcellular distribution of 67Ga in each organ were investigated. At 10 min after administration of 67Ga-citrate the retention value of 67Ga in blood was 6.77% dose/g, and this value decreased with time. The values for skeletal muscle, lung, pancreas, adrenal, heart muscle, brain, small intestine, large intestine and spinal cord were the highest at 10 min after administration, and they decreased with time. Conversely, this value in bone increased until 10 days after injection. But in the liver, kidney, and stomach, these values increased with time after administration and were highest 24 h or 48 h after injection. After that, they decreased with time. The value in spleen reached a plateau 48 h after administration, and hardly varied for 10 days. From the results of subcellular fractionation, it was deduced that lysosome plays quite an important role in the concentration of 67Ga in small intestine, stomach, lung, kidney and pancreas; a lesser role in its concentration in heart muscle, and hardly any role in the 67Ga accumulation in skeletal muscle. In spleen, the contents in nuclear, mitochondrial, microsomal, and supernatant fractions all contributed to the accumulation of 67Ga.

Abstract
Normal male rats were injected with either gallium citrate Ga 67 or sodium sulfate S 35. After 24 h, the stomach, small intestine, pancreas, and muscle were excised and homogenized. After the removal of the nuclear fraction, each of these homogenates was digested with protease. After digestion, the supernatants of the reaction mixtures were applied to a Sephadex-G-100 column. The radioactivity was eluted with buffer solution. The resultant eluates were analyzed for radioactivity and the levels of proteins, uronic acids, and sialic acids. In all four organs, sizable amounts of 67Ga were bound to sulfated acid mucopolysaccharides with molecular masses of about 10,000 daltons and to sulfated acid mucopolysaccharides, a species whose molecular masses exceed 40,000 daltons. In the stomach, large amounts of 67Ga were bound to sulfated acid mucopolysaccharides with molecular masses of about 10,000 daltons. From these results, it is obvious that the main 67Ga-binding substances in these four organs are sulfated acid mucopolysaccharides, and that these acid mucopolysaccharides play the most important role in the concentration of 67Ga in these organs.

Abstract
The kinetic and pharmacological characteristics of 3H-spiroperidol binding sites were studied in slide mounted sections of rat forebrain, and optical binding conditions were defined. Using the receptor macroautoradiographic techniques with tritium-sensitive LKB sheet film, the distribution of dopamine (D2) receptor was determined in slices including striatum of rat brain. The autoradiograms were analyzed using Video Digitizer System combined with video camera and minicomputer, and the subtraction images were obtained. These studies suggest that this quantitative receptor macroautoradiography might be useful in the explanation of etiology in the field of neuro-psychiatric diseases and the fundamental studies of positron emission computed tomography, since this method has several advantages over in vivo autoradiography and in vitro receptor assay.

Abstract
The results of 201Tl per-rectal scintigraphy in 10 patients with primary hepatocellular carcinoma (HCC) were presented together with the findings from contrast angiography, computed tomography and ultrasonography. 201Tl accumulation within the tumour was seen in seven of ten patients. This accumulation was thought to be due to 201Tl supply not from the portal vein but from the hepatic artery since significantly high heart to liver uptake (H/L) ratio from 0.71 to 1.21 and clear visualization of the heart and kidneys, indicating the presence of abundant portal-to-systemic shunting, were observed. Another three patients showed negative 201Tl accumulation within the tumour and near-normal H/L ratios from 0.32 to 0.47 which indicates little portal-to-systemic shunting. This finding reveals the evidence of the lack of 201Tl supply to the tumour from the portal vein. It seems that HCC does not receive any significant amount of blood flow from the portal system.

Abstract
The growth and ochratoxin A production of Aspergillus ochraceus strains S-235-100 and IFM 0458, which were isolated from green coffee beans and glutinous rice, respectively, were examined in yeast extract-sucrose (YES) medium containing 0.1 to 1.0% caffeine. The mycelial growth and ochratoxin A formation of strain IFM 0458 was inhibited by caffeine at concentrations over 0.1%, and ochratoxin A was not produced at caffeine levels of 0.5% and 1.0%. Contrary to this, A. ochraceus strain S-235-100 produced a larger amount of ochratoxin A in the presence of 0.5% and 1.0% caffeine when grown on YES medium, reaching a maximum after 15 to 20 days of incubation. The formation of ochratoxin A by nine additional strains of A. ochraceus, three strains of A. elegans and one strain of A. sclerotiorum isolated from green coffee beans was determined on rice and ground green coffee media. A significant degree of degradation of caffeine in the green coffee medium was demonstrated with cultures of nine A. ochraceus isolates from green coffee beans. Most of these isolates showed the potential to grow on moist green coffee beans and to produce a significant amount of ochratoxins.

Abstract
In the previous paper, we reported that 67Ga was accumulated in abscess and uptake rate of 67Ga in abscess increased with time after the injection of 67Ga-citrate. The present study was undertaken to elucidate the influence of blood flow on the accumulation of 67Ga in abscess. Five days after subcutaneous injection of 0.2 ml of turpentine to the rats, 131I-human serum albumin (HSA) was injected intravenously to the rats. At an appropriate time after the injection (10 min to 6 days), uptake rates of 131I-HSA in abscess and normal tissues were measured. Similarly, 51Cr-red blood cells (RBC) were injected intravenously to the above rats and the uptake rates of 51Cr-RBC were also measured. One, three, and 24 hours after injection of 131I-HSA, the uptake rates of 131I-HSA in abscess were 1.32 %dose/g, 1.84 %dose/g, and 0.82 %dose/g, respectively. However, the uptake rates of 51Cr-RBC in abscess was very small, and the value was 0.14 %dose/g at 24 hours after the injection. In the case of abscess, blood in the tissue fluid was very little, but the permeability of 131I-HSA from the blood vessel in the tissue was much larger than that of normal tissues. From these facts, it was deduced that the accelerated permeability caused the abscess accumulation of 67Ga.

Abstract
The purpose of this study was to evaluate the usefulness of tomographic phase analysis in detecting the site of the accessory conduction pathway (ACP) in patients with Wolff-Parkinson-White (WPW) syndrome. Gated emission computed tomography and planar gated blood pool scintigraphy were performed in 20 patients with WPW syndrome, 14 with delta waves and six without delta waves (two intermittent types and four concealed types). The abnormal initial contractions in both planar and tomographic phase images were compared with the sites of ACPs confirmed by epicardial mapping and surgery. The atrioventricular ring was divided into eight segments on each side, and the identification of the initial phase in the segment in which the ACP was located, or that adjacent to it, was considered to be the correct diagnosis. In planar phase analysis, the abnormal initial phase was identified correctly in 8 of 14 patients (57%), whereas in tomographic phase analysis, the site of the ACP was detected in 12 of 14 patients (86%). Tomographic phase analysis can be a helpful adjunctive method in patients with WPW syndrome.
