As there are few data on primary structures of fish apolipoproteins (apo), we determined the N-terminal sequence of a 28 kDa major serum protein of rainbow trout, a possible homologue of apoAI protein in higher vertebrates. Rainbow trout serum was separated by two-dimensional electrophoresis. A spot of the 28 kDa protein (pl 5.

Monoclonal antibodies (MoAbs) against Theileria sergenti Fukushima stock, an intraerythrocytic protozoan parasite of cattle, were produced. The MoAbs reacted with 32 kDa or 23 kDa piroplasm surface protein (p32 or p23) in Western blot analysis. Using a panel of the MoAbs, antigenic analysis of the stocks and field isolates distributed in Japan was carried out.

In Zambia, theileriosis manifests itself in the form of Corridor disease (CD), caused by Theileria parva lawrencei, and East Coast fever (ECF), caused by T. parva parva. Of the approximately 3 million cattle in Zambia, 1.

We examined the relationship between cellular glutathione (GSH) level and susceptibility to lymphokine-activated killer (LAK) cell-mediated cytolysis in KB human pharyngeal carcinoma cells. Treatment of KB cells with D,L-buthionine-S,R-sulfoximine (BSO), a gamma-glutamyl cysteine synthetase blocker, resulted in decreased total intracellular GSH levels associated with increased susceptibility to LAK killing. In contrast, treatment with oxothiazolidine-4-carboxylate (OTZ, a precursor of cysteine), which is known to increase cellular GSH level, decreased the susceptibility of KB cells to LAK killing.

Recent studies have revealed that altered mineral and vitamin D metabolism is observed in diabetic patients with the complication of osteopenia. In order to elucidate the role of parathyroid hormone-related peptide (PTHrP) on calcium homeostasis in diabetes, we have measured the serum level and urinary excretion of PTHrP as well as other serum calcium-regulating hormones in 106 patients with non-insulin-dependent diabetes mellitus (NIDDM) and 43 control subjects. The serum concentration of intact PTH was 2.

The gene for the 32 kDa surface protein (p32) of Theileria sergenti was cloned into lambda gt11 and its nucleotide sequence was determined. The gene encodes a protein of 283 amino acids as deduced from its nucleotide sequence with a 22 residue N-terminal signal peptide. Using this cDNA as a probe we have isolated another two clones from a cDNA library with a CDM8 vector system derived from the same parasite stock.

A pair of synthetic oligonucleotide primers, designed from the gene encoding a 32-kDa intraerythrocytic piroplasm surface protein of Theileria sergenti, were used to amplify parasite DNA from the blood of T. sergenti-infected cattle by means of the polymerase chain reaction (PCR). PCR-amplified DNA was examined by electrophoresis and by dot blot or microplate hybridization using a parasite-specific cDNA probe.

For the purpose of obtaining basic data and for establishing a support system for elderly people with various health and social problems, a population survey was performed in 1990 to investigate the health and living conditions of elderly people living alone, elderly couples and the bedridden elderly in the town of Shigaraki, Shiga Prefecture. A total of 275 subjects (103 male, 172 female) 65 years of age and over were surveyed. The participation rate in this survey was 88.

Restriction fragment length polymorphisms (RFLPs) of Theileria sergenti DNA were analysed using probes of a genomic DNA fragment (pTs 2) and a cDNA corresponding to this genomic probe (C-Ts 2). Each of the probes detected RFLPs in DNA from different stocks of Theileria sergenti. Additionally, using these probes, alterations in hybridization patterns were observed in samples of the parasites harvested at different times after individual calves had been infected with Theileria sergenti.

Epitopes on a 32 kDa protein, which is an immunodominant major surface protein of Theileria sergenti, recognized by anti-merozoite monoclonal antibodies were characterized. The results of a competitive binding assay between monoclonal antibodies indicated that there were at least three epitopes in this protein. The presence of repeated epitopes was suggested by using two-site enzyme-linked immunosorbent assay.

The pharmacological effects of the toad venom-containing drug "kyushin" on aconitine- and thyroxine-induced arrhythmia in guinea pigs, on the conduction system in Langendorff preparations of rabbit hearts and on the autonomic nervous system in cats were studied. "kyushin" significantly inhibited the aconitine-induced arrhythmia after intraduodenal administration (i.d.

The nucleotide sequences of the cDNAs encoding a 33-kDa piroplasm protein of Theileria sergenti (p33) and a similar protein of Theileria buffeli (p34) were determined. Both of the genes contained an open reading frame of 849 base pairs. The predicted amino acid sequence of p33 and p34, consisting of 283 residues, showed 82% similarity.

The lysate of Theileria sergenti piroplasms was tested for proteinases using sodium dodecyl sulfate-polyacrylamide gel electrophoresis in which substrate was included in gel matrix. Six proteinases of molecular weight 330, 125, 98, 94, 67 and 58 kilodalton (kDa) were detected. From the results of the Triton X-114 phase partition, 330, 125 and 58 kDa proteinases were partitioned into aqueous phase, which indicated that they were not associated with parasite membranes.

Theileria parva is an obligate intracellular protozoan parasite which is the causative agent of East Coast fever, an acute, leukemia-like disease of cattle. The intralymphocytic stage of the parasite induces blastogenesis and clonal expansion of quiescent bovid lymphocytes. Experiments in our laboratory have shown a marked increase of casein kinase II- (CK II-) like activity in T.

The influence of aminotriazole treatment on primary bile acid biosynthesis was studied in detail. After administration of aminotriazole to rats, bile was collected for 8 h. The content of chenodeoxycholic acid in the bile was increased to 144% of the control by aminotriazole treatment, but that of cholic acid was decreased to 48.

Pharmacological effects of Gosha-jinki-gan-ryo extract (KJE) on experimental diabetes induced by cyproheptadine (CPH), aldose reductase activity, and experimental peripheral neuropathy were studied. The effects of KJE were compared with those of Hachimi-jio-gan-ryo extract (HJE). KJE at 417 mg/kg/day (5 times the daily dose in humans) and HJE at 367 mg/kg/day (5 times the daily dose in humans) significantly inhibited the decrease in glucose tolerance by CPH.
