    Description: A laboratory based 2x3 factorial experiment was conducted for 12 weeks to investigate the influences of dietary lipid and phosphorus (P) levels on retention and excretion of phosphorus and nitrogen (N) in fingerling red sea bream. Twolevels of lipid (210 and 260 g/kg) and three levels of phosphorus (17, 14 and 12 g/kgˉ¹) in the dry diets were tested. Duplicate groups of 25 red sea bream (averageweight 3.74±0.07 g) per 60L glass tank were fed experimental diets three times a day near to satiation level at 22 to 28°C water temperature. A reduction in dietary fish meal from 500 to 300 g/kg dry diet, corresponding to a supplementation in both dietary lipid and P resulted in significant increase in both P and N retention which resulted in the reduction of their excretion by red sea bream. The overall results of the present study demonstrated that both lipid and phosphorussupplementation are necessary for developing less-polluting feed which in turn, reduce fish meal level in the diet of fingerling red sea bream. Further studies in this regard with different size and age groups of red sea bream are warranted.

    Description: A laboratory based 2 x 2 factorial experiment was conducted to investigate theinfluences of dietary phosphorus and zinc levels on growth and bone mineralization infingerlings of rainbow trout for 21 weeks. Two levels of phosphorus (19 and 30 mg/g)and two levels of zinc (55 and 103 Ag/g) in the dry diets were tested. Duplicate tanks of30 rainbow trout (average weight 1.56 ± 0.24 g) per 60L glass tank were fedexperimental diets three times a day to apparent satiation level at 15 to 24°C watertemperature. The results of the present study demonstrated that dietary phosphorussupplementation influenced the growth and bone mineralization whereas zinc levelssignificantly (p〈0.05) influenced bone mineralization in rainbow trout. Furtherinvestigations in this area with different size and age groups of this fish are broadlyneeded.

    Notes: Abstract A new type absolute-humidity sensor with very quick response, very small power consumption and high sensitivity, which is based on the detection of the thermal conductivity change in humid air at heated temperature above 400°C, has been developed and demonstrated. Since this new type absolute-humidity sensor is able to be easily heated up above 400°C within 30–40 msec because of a micro-air-bridge heater structure, the surface of its sensing area is refreshed by burning out adsorbed dusts, oil, etc. Thermal conductivity λmix of mixed gas expressed by Sutherland-Wassiljewa equation is applied to the humid air to study this absolute humidity sensor. Only a single micro-air-bridge heater operation driven by double pulse-currents for this humidity sensor is also proposed.

    Effect of the calcium antagonist nilvadipine on haemodynamics at rest and during cold stimulation in essential hypertension (1987)

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The immediate haemodynamic effects of the calcium antagonist nilvadipine have been studied in ten patients with established mild essential hypertension. Nilvadipine 4 mg p.o. reduced both the systolic and diastolic blood pressures within 60 min, associated with a fall in total peripheral resistance and an increase in heart rate and cardiac index. The peak of blood pressure and total peripheral resistance reached during a cold pressor test were reduced by nilvadipine, but it did not affect the haemodynamic responsiveness to cold stimulation. Plasma renin activity was unaltered and the plasma noradrenaline concentration was increased only slightly. Thus, nilvadipine lowered blood pressure at rest and during cold stimulation as a result of arteriolar dilatation. The hypotensive effect at rest was associated with a reflex increase in heart rate and cardiac index.

    Effect of nicardipine on haemodynamic response to stress in hypertension (1992)

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The effects of the calcium antagonist nicardipine on the pressor response to mental arithmetic, cold pressor and exercise tests have been studied in fifteen patients with established mild to moderate essential hypertension. Nicardipine 20 mg p.o. showed a hypotensive effect within 60 min, associated with a fall in total peripheral resistance and an increase in heart rate. As the pressor response to each stress was not affected by nicardipine, the peak blood pressure reached during each stress was lower. Nicardipine lowers blood pressure at rest as a result of arteriolar dilatation, associated with reflex tachycardia. The pressor responsiveness to various stresses was not affected by nicardipine.

    Pharmacokinetics of TZU-0460, a new H2-receptor antagonist, in patients with impaired renal function (1986)

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary We have studied pharmacokinetics of a new H2-receptor antagonist, TZU-0460, in patients with varying degrees of renal impairment. The apparent volume of distribution at steady-state was 1.70 l/kg, and the plasma protein binding of TZU-0460 or its active metabolite, desacetyl TZU-0460 was less than 10% in normal subjects. These variables were not altered with renal impairment. Sixty percent of TZU-0460 given orally was excreted via the kidney, mainly by tubular secretion. The half-time of elimination was 3.94 h in normal subjects, and was prolonged to 12.13 h in severe renal failure (creatinine clearance below 30 ml/min/1.48 m2). Dosage adjustment of TZU-0460 is necessary in renal failure.

    Pharmacokinetics of SUN 1165, a new antiarrhythmic agent, in renal dysfunction (1991)

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The pharmacokinetics of a new Class I antiarrhythmic agent, SUN 1165, has been studied in 32 patients with varying degrees of renal impairment following a single oral dose of 50 mg. The apparent volume of distribution at steady state was 1.48 1 · kg−1, the absorption rate constant was 2.2 h−1, and plasma protein binding was 26.8% in subjects with normal renal function. These variables were not altered with renal impairment. More than 60% of SUN 1165 given orally was excreted unchanged via the kidney, both by tubular secretion and glomerular filtration. The elimination rate constant, the apparent total body clearance and the apparent renal clearance were linearly correlated with the endogenous creatinine clearance. The half-time of elimination was 3.4 h in normal subjects and it was prolonged to 23.7 h in severe renal failure (creatinine clearance below 20 ml · min−1 · 1.48 m−2). Dosage adjustment of SUN 1165 is necessary in renal failure.

    Renal effects of manidipine hydrochloride (1993)
    Springer
    European journal of clinical pharmacology 45 (1993), S. 321-325

    ISSN: 1432-1041
    Keywords: Manidipine ; Essential hypertension ; renal function ; glomerular hypertension
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The renal effects of manidipine hydrochloride were investigated in ten hospitalised patients with mild-to-moderate essential hypertension. After a one-week placebo period, manidipine was given for 1 week in a dose rising from 5 mg to 10 mg or 20 mg daily to normalise the mean blood pressure measured after 2 h. Blood pressure had decreased from 171/101 to 147/86 mm Hg at the end of manidipine treatment. The pulse rate was unaltered. Renal vascular resistance decreased from 1.90 to 1.33 dyn · s · cm−5/1.48 m2 × 104, and renal blood flow and glomerular filtration rate increased from 522 to 662 ml · min−1 · 1.48 m−2 and from 81 to 93 ml · min−1 · 1.48 m−2, respectively, in spite of a fall in renal perfusion pressure. Manidipine reduced the filtration fraction from 0.260 to 0.243, suggesting a preferential reduction in efferent arteriolar resistance. The fractional excretion of sodium and potassium did not change. Manidipine did not produce any significant alteration in plasma renin activity or in the plasma aldosterone concentration. The results indicate that manidipine has favourable renal effects and a concomitant hypotensive action in patients with mild-to-moderate essential hypertension.
