    A survey on nutritional status of vitamin B1 intake was carried out on middle-aged farming (n=196) and clerical couples (n=206) living in Kyushu in 1985 and 1980. The results of the survey were as follows. 1) In 30 farming couples, blood vitamin B1 levels were very low (40.68±20.04ng/ml for husbands and 33.16±12.77ng/ml for wives), and 60.0% of husbands and 73.3% of wives had levels less than 40ng/ml. 2) Amount of vitamin B1 intake was 0.78±0.38mg/day and 0.65±0.32mg/day (loss of vitamin B1 by cooking estimated at 50%) on average in husbands and wives, respectively. Proportions of intake relative to the requirement calculated from total energy intake (0.4mg/1, 000kcal) were 80.4% and 81.3%, respectively. 3) Both farming and clerical couples showed relatively low intake of vitamin B1. 4) The amount of vitamin B1 intake tended to be insufficient under conditions of higher rice intake.

    The effects of indigestible dextrin on lipid and glucose metabolism were investigated in experimental animals and hyperlipidemic patients with non-insulin-dependent diabetes mellitus (NIDDM). In the animal experiment, SD rats were fed for two weeks with a cholesterol-free standard diet, then 5% indigestible dextrin was added for 9 weeks. In the NIDDM patients, 20g of indigestible dextrin was administered with each meal for 12 weeks. Changes in serum lipid levels and fasting plasma glucose concentrations were monitored periodically. In the rats fed indigestible dextrin, levels of serum cholesterol and plasma glucose were significantly decreased at the end of the study. Even in the hyperlipidemic diabetic patients, after 12 weeks of administration of indigestible dextrin, fasting serum cholesterol and plasma glucose concentrations were significantly decreased. These results show that indigestible dextrin as soluble dietary fiber is effective for improving hyperlipidemia and glucose tolerance.

    The inhibitory actions of AO-128, an N-substituted derivative of valiolamine, on intestinal α-, glucosidase activity and postprandial hyperglycemia were examined in rats. AO-128 showed about 2Q-30-fold more potent inhibition of semi-purified parcine small intestine disaccharidases and about 190-3, 900-fold more potent inhibition of purified rat small intestine sucrase-isomaltase (S-I) complex than acarbose, a typical α-glucosidase in hibitor. on the other hand, the inhibitory activity of AO-128 on α-amylase was only 1/3, 400 that of acarbose. AO-128 suppressed the elevation of blood glucose after oral administration of sucrose, maltose or starch, but had no effect on the elevation due to ingestion af glucose, fructose or lactose, In rats receiving AO-128, adipose tissue weight was reduced, and intestinal disaccharidase activities were inhibited completely, even though the S-I complex content was increased.

    The ameliorating activity of an intestinal disaccharidase inhibitor, AO-128, was evaluated in rats with diabetes of varying severity. Diabetic rats were produced by injecting 120mg/kg streptozotocin (STZ) into 1.5- and 5-day-old neonates. From the age of 9 week, the rats were given AO-128 as a dietary admixture at a dose of 5 mg/100g of diet for 28 days. AO-128 normalized the basal levels of plasma glucose, which were elevated, and both glucose tolerance and insulin response, which were impaired in animals injected with STZ at the age of 1.5 days. On the other hand, animals administered STZ at the age of 5 days showed overt diabetes syndrome including features such as hyperglycemia, hypoinsulinemia, hyperphagia, polydipsia, polyuria and glucosuria. AO-128 partly ameliorated these diabetic symptoms.

    The distribution of enteroglial cells in the enteric nerve plexuses of the rat small intestine was examined immunocytochemically using an improved peroxidase-antiperoxidase method with antiserum against S-100b protein. Enteroglial cells and enteroneuronal projections were stained at the same time by the Champy-Maillet (ZIO) method. It was demonstrated that the enteric nerve plexuses extended into the mucous coat, the submucous coat including the submucous plexus, the circular muscle layer, the myenteric plexus, the longitudinal muscle layer and the serous coat. The enteric nerve plexuses constituted a three-dimensional network of ganglia, primary and secondary nerve strands and tertiary nerve strands, termed the autonomic ground plexus. The submucous plexus contained numerous small ganglia, whereas the myenteric plexus contained many long and large ganglia. The autonomic ground plexus in the myenteric plexus formed loose networks.

    The effects of feeding palatinose and its condeasates (PC) to rats for 13 weeks on the contents of Ca, Mg, P, Fe, Zn, Cu and Mn in various tissues were examined. There were no significant differences in body weight, hematocrit and tissue mineral (Ca, Mg, P and Fe) contents between the control and other groups, except for a sigmificantly higher plasma P content in the PC group. On the other hand, with regard to trace minerals (Zn, Cu and Mn), remarkable changes were observed, especially by the PC intake. These included an increase of Zn concentration in the brain, an increase of Cu concentration in the liver and kidney, an increase of Mn concentration in the brain and tibia, and a decrease of Mn concentration in the liver.

    Four-week-old Wistar male rats were fed a vitamin E (VE) -deficient diet for 8 weeks, followed by intraperitoneal injection of DL-buthionine- [S, R] -sulfoximine (BSO), an inhibitor of γ-glutamylcysteine synthetase, at 1mmol/kg body weight once a day for 3 days. Rats in a glutathione (GSH) treatment group were injected intraperitoneally with GSH monoisopropyl ester at 2.5mmol/kg body weight twice a day for 3 days in addition to BSU administration. The TBA (2-thiobarbituric acid) value, GSH conetnt, lipofuscin content and enzyme activities in the kidneys of rats, and BUN (blood urea nitrogen) content, creatinine conent and LDH (lactate dehydrogenase) activity in their sera were measured. GSH depletion by BSO administration decreased the renal TBA value, and increased markedly the renal lipofuscin content, The increase of renal lipofuscin was partly prevented by GSH treatment. The increase in serum creatinine and the decrease in renal enzyme activities of rats administered BSO were inhibited by GSH treatment, but the treatment could not completely protect against necrosis of the proximal renal tubule epithelia. It appears that lipid peroxides produced by VE deficiency may cause the accumulation of lipofuscin under renal GSH depletion, followed by necrosis of the proximal renal tubule epithelia. These results suggest that GSH has an important role in preventing lipofuscin production through the reaction of lipid peroxides with amino acids.

    Polycyclic aromatic sulfur heterocycles (PASH) were identified and determined in 15 kinds of tea leaves and 2 kinds of healthy food by capillary FPD/GC and capillary GC/MS. Benzo [b] naphtho [2, 1-d] thiophene, benzo [b] naphtho [2, 3-d] thiophene, chryseno [4, 5-bcd] thiophene and benzo [2, 3] phenanthro [4, 5-bcd] thiophene were identified in tea leaves. Alkyl (methyl, dimethyl) derivatives of benzonaphthothiophenes were also identified using mass chromatography (m/z=234, 248, 262). Samples produced in foreign countries contained higher levels of PASH (258≥MW≥234) and PAH (252≥MW≥228) than Japanese ones. The ratio of total-PASH to total-PAH was approximately within the range 0.1-0.3.

    The effects of hemicellulose (“hemicellulose B”fraction) isolated from corn and wheat bran, on growth, apparent utilization ratio of nutrients and gastrointestinal transit time, were investigated in rats and compared with those of refined corn bran (RCB). (1) Two different hemicelluloses (CBH, WBH) and RCB were added to the diet at a level of 1% for the former and 5% as DF for the latter. These diets were given to weaning rats for 28 days. Both diets, containing CBH or WBH, had no effect on the growth of rats, whereas the ceca in both rat groups were enlarged. The apparent utilization ratios of starch and fat were very similar in all dietary groups. However, CBH, WBH and RCB exerted weak inhibitory effects on the utilization ratio of protein. (2) Gastrointestinal transit time and water content of feces ware examined in adult rats. The mean transit times were 43.1h for CBH, 38.9h for WBH, 32.5h for RCB and 50.8h for the DF-free group. Fecal moisture was increased markedly in the RCB diet group. These results indicate that hemicellulose isolated from corn and wheat bran (CBH and WBH) is effective for shortening of gastrointestinal transit time in rats without adversely affecting growth and digestion and absorption of nutrients.

    The concentrations of free amino acids in plasma of patients with multiple myeloma (MM), malignant lymphoma (ML) and chronic renal failure (CRF) were determined using an automatic amino acid analyzer. Values of plasma ΣNEAA (total non-essential amino acids) in patients with MM, ML and CRF were higher than in normal subjects. Therefore, ΣEAA (total essential amino acids) /ΣNEAA ratios (E/N ratios) in patients with MM, ML and CRF were significantly lower than in normal subjects. The ratio of branched-chain amino acids to aromatic amino acids (Fischer's ratio) in patients with MM and ML was significantly lower than in normal subjects.
