Fowl cholera found in imported myna birds (Eulabes intermedia).

Of 480 myna birds imported from Thailand in 1976, 54 birds died shortly after arrival in Japan. Bacteriological and pathological examination were carried out on seven of them. Pasteurella multocida was almost purely isolated from all the liver, heart, spleen and trachea examined. Somatic antigen of the isolants was O-5 of Namioka and Murata. Dissection revealed hyperemia of the trachea, edema of the lungs, increase of pleural fluid, and petechial or ecchymotic hemorrhages in the liver, heart and duodenum. Minute necrotic foci in the liver and bacterial clumps in the foci, pulmonary exudate and septa were found under the microscope. Severe pathogenicity of one of the isolated strains was proved by inoculation of 50-day-old broiler chickens with 10(3)-10(5) viable cells and by death within 18 hours, following the inoculation.

Clinical evaluation of 201thallium chloride scan for thyroid nodule.

Thyroid scintigraphy with Tl in the evaluation of nodules was investigated. A Tl scan was performed on 55 patients with thyroid nodules previously scanned with Tc or I. In the case of 16 carcinomas, accumulation of Tl was shown in every case. In addition, some lymph node metastases were depicted. (Accumulation was noted also in some of the metastatic lymph nodes.) Cold defect was delineated in ten cases of colloid and fetal adenoma, although accumulation was shown in four cases of Hürthle and embryonal adenoma. Six cases of degenerative cysts were delineated as cold defect. As for colloid nodular goiter, the affinity to the individual nodule was not constant. In general, degenerative and cystic nodules showed less activity and hyperplastic solid nodules showed more activity than normal tissue. We concluded that although a Tl scan cannot differentiate between benign and malignant tumors satisfactorily, it is nevertheless useful for determining surgical indication, as the case showing Tl accumulation on the scan is malignant or benign tumor with poorly differentiated solid type and possiblility of further growth and malignant change.

The nucleotide sequence of human fibroblast interferon cDNA.

DNA synthesized by in vitro reverse transcription of the interferon mRNA has been cloned and amplified as recombinant DNA, TpIF319-13 (Taniguchi et al., 1979). The nucleotide sequence of this IF cDNA which consists of 770 bp (excluding the A:T tails) has been determined. The data reported predict the hitherto unknown amino acid sequence of human fibroblast interferon and its putative signal peptide.

Molecular cloning of human interferon cDNA.

A hybrid plasmid, TpIF319, has been shown to contain the sequence for human fibroblast interferon mRNA [Taniguchi, T., Sakai, M., Fujii-Kuriyama, Y., Muramatsu, M., Kobayashi, S. & Sudo, T. (1979) Proc. Jpn. Acad. 55, Ser. B, 464-469]. This conclusion was confirmed by a hybridization-translation assay, using rabbit globin mRNA and its cDNA-containing plasmid as a control. Plasmid TpIF319 was used as probe and another recombinant plasmid, TpIF319-13, whose cDNA insert consists of about 800 base pairs, was isolated. Nucleotide sequence analysis of the cDNA revealed that the DNA in fact codes for human fibroblast interferon.

Expression of the human fibroblast interferon gene in Escherichia coli.

We applied the method of Guarente et al. [Guarente, L., Lauer, G., Roberts, T.M. & Ptashne, M. (1980) Cell 20, 543-553] to construct plasmids that direct expression in Escherichia coli of the human fibroblast interferon (F-IF) gene. Two plasmids were recovered. One directs efficient synthesis of a protein whose primary sequence is that of pre-F-IF and the other, that of mature F-IF. Extracts of bacteria synthesizing mature F-IF display antiviral activity characteristic of human F-IF. This activity is lower than that expected from the differential rate of synthesis of the protein. We have detected no such activity in extracts of bacteria synthesizing pre-F-IF.

Purification and characterization of galactosyltransferase in human parotid saliva.

The galactosyltransferase has been purified from human parotid saliva by ammonium sulfate precipitation (25-70% saturation), followed by repeated affinity chromatography on Sepharose-alpha-lactalbumin. The molecular weight of the enzyme was estimated to be approximately 56,000. The enzyme catalyzes the transfer of galactose from UDP-galactose to the exposed N-acetylglucosamine residues derived from glycoproteins, forming a Gal beta (1-4)GlcNAc linkage.

Hypolipidemic effects of S-methylmethionine (vitamin U) using various experimental procedures.

The hypolipidemic and anti-atheromatous effect of S-methylmethionine sulfonium chloride (Vitamin U, MMSC) were investigated using various experimental procedures. In the results, orally administered MMSC markedly normalized dietary-induced hyperlipidemia in rats and rabbits, demonstrating the lowering effects on plasma total cholesterol, beta-lipoprotein and phospholipids, and no appreciable effect on plasma triglycerides. In normolipidemic and a surfactant-induced hyperlipidemic rats, MMSC did not decrease plasma lipids level, nor MMSC-affected plasma lipoprotein lipase and liver catalase activities. In contrast, clofibrate showed little or no effect on plasma lipids level of dietary-induced hyperlipidemic rats, with exception of plasma triglycerides, whereas clofibrate lowered plasma lipids level in normolipidemic and surfactant-induced hyperlipidemic rats, and enhanced liver catalase activity. From the results, the lipids lowering effects of MMSC using various procedures were clearly differentiated from those of clofibrate. Additionally, the anti-atheromatous effect of MMSC was histopathologically demonstrated in dietary-induced ahteromatous rabbits. A unique hypolipidemic effect of MMSC is discussed from therapeutic viewpoint.
