The utilization of urea nitrogen was examined in 10 healthy adult men from a village near Lufa, in the Eastern Highlands Province of Papua New Guinea. The staple diet of these men was sweet potatoes. [15N]urea was used as tracer for urea released into their intestinal tracts and the utilization of the urea-N was estimated from the trend of 15N. The men were(More)
We compared the visceral fat accumulation between Indonesians and Japanese. Non-obese (25>BMI> or =18.5) men aged between their 20s and 50s were collected in Toban including moderately populated middle-sized cities of Hyogo Prefecture in Japan, and Sangsit town and Pedawa village in Indonesia. Their visceral fat accumulation was assessed by determination of(More)
For determination of the responses of sodium balance, blood pressure, and other relevant variables to Na loading in people with a low intake of Na, 10 male Papua New Guinea highland subjects were given additional Na at two levels (128 and 256 mmol/d) for 10 d after a 3-d control period of low-Na diet. Na loading caused a marked positive balance of Na,(More)
A nutritional survey was held in August, 1978, at Kalugaluvi (altitude: 1,500m) near Lufa, which is 60 km from Goroka, in the Eastern Highland Province of Papua New Guinea. Anthropometric measurements were carried out on 55 males and 37 females aged from 7 to 64 years. whereas the physiques of the children looked as good as those of Japanese of a comparable(More)
We found alpha-glucosidase inhibitory effect of Zn(II) complex with 6-methyl-2-picolinmethylamide (6mpa-ma) which showed the highest blood glucose lowering effect in Zn(II) complexes with picolinamide derivatives in KK-A(y) mice. The Zn(II) complex showed strong alpha-glucosidase inhibitory activity greater by about eighty times (substrate: maltose) and(More)
A study on the prevalence of coronary heart disease (CHD) and its risk factors in Ceningan Island was conducted. The prevalence of CHD was 11.5%. Older age (odds ratio, OR, 27.0), underweight (OR, 3.6), systolic hypertension (OR, 4.6), high total cholesterol (OR, 5.9), and high low-density lipoprotein cholesterol (OR, 3.1) were risk factors for a history of(More)
Endogenous nitrogen excretion was examined in highlanders of Papua New Guinea. Eight highlanders were fed a semisynthetic protein-free diet with about 49 kcal/kg of energy for 11 days. At the end of this period they excreted 29.2 +/- 4.0 mg N/kg of urinary nitrogen and 13.9 +/- 2.5 mg N/kg of fecal nitrogen per day. When the values were expressed per basal(More)
AIMS Previous studies reported the anti-diabetic effects of α-lipoic acid (αLA) isomers: racemic-αLA, R-αLA, or S-αLA. Previously, we examined the anti-diabetic effects of αLA administered as a food additive, but were unable to demonstrate the differences among different isomers. In this study, αLAs were complexed with γ-cyclodextrin (γCD) for the(More)
We prepared 4 new Zn(II) complexes with Zn(O4), Zn(N(2)O(2)), and Zn(S2O2) coordination modes and evaluated their insulinomimetic activities in an in vitro study. The insulinomimetic activities of bis(pyrrole-2-carboxylato)zinc (Zn(pc)2), bis(alpha-furonic acidato)zinc (Zn(fa)2), bis(thiophene-2-carboxylato)zinc (Zn(tc)2), and bis(thiophene-2-acetato)zinc(More)
