Patients were randomly allocated to one of two groups; intravenous or epidural analgesia, with twenty patients in each group. General anesthesia was induced with thiopentone 5-6 mgkg-1 and maintained with 0.8-1.0% isoflurane and 66% nitrous oxide in 33% O2. The trachea was intubated after administration of vecuronium 0.1 mgkg-1. Patients in the epidural analgesia groups then received, by random...

LIFSCHITZ, M. D., AND R. I. HENKIN. Circadian variation in copper and zinc in man. J. Appl. Physiol. 31(l): 88-92. 1971.~Copper and zinc metabolism were studied in 10 normal volunteers on a constant regimen consisting of an alternate 4 hourly intake of a liquid diet or distilled water, and a regulated amount of activity. Urine was collected in 4-hr periods and blood samples drawn in the middle ...

Biological uranium reduction was investigated using bacteria isolated from a uranium mine in Limpopo, South Africa. Background uranium concentration in soil from the mine was determined to be 168 mgkg(-1) much higher than the typical background uranium concentration in natural soils (0.30-11.7 mgkg(-1)). Therefore it was expected that the bacteria isolated from the site were resistant to U(VI) ...

Comparative Effects of Diaxepam and Midazolam on Paraoxon Toxicity in Rats. KRUTAKKROL, H., AND DOMINO, E. F. (1985). Toxicol. Appl. Pharmacol. 81,545-550. The present study was undertaken to compare the effectiveness of a new water-soluble benzodiazepine, midazolam, to diazepam, both administered im for protection against diethyl-pnitrophenyl phosphate (paraoxon) toxicity. Adult male Sprague-D...

Purpose: To investigate the effect of Flueggea leucopyrus Wild aqueous extract (FLAE) on the urinary output of rats. Method: Three different doses of FLAE (500, 1000 and 1500 mgkg), furosemide (13 mg kg as diuretic reference) and distilled water (as control) were orally administered to healthy adult hydrated rats. Cumulative urine output was monitored hourly over 6 h. Selected urinary parameter...

Male Malin x Polled Dorset crossbred sheep were stall-fed with grass (10%) and PKC (90%) and supplemented with either zinc at 500 ug/g, as zinc sulfate (PKC+Zn group) or zinc (113 ug/g) and ammonium molybdate (500 ug/g) (PKC+Zn+Mo group) or unsupplemented diet (PKC group) for 20 weeks. Another group which acts as a control was fed with a diet consisting of corn and fish meal (2 0%) and grass (8...

OBJECTIVE Determine the effect of a matrix metalloproteinase inhibitor (MMPi) and angiotensin converting enzyme inhibitor (ACEi) on collagen, MMP, tissue inhibitors of MMPs (TIMPs) expression in the spontaneously hypertensive heart failure (SHHF) rat. METHODS Six groups were tested: normotensive 9- and 13-month-old Wistar-Furth (WF) rats, 9-month-old SHHFs (compensatory hypertrophy), 13-month...

This study aims at determining the level of pollution heavy metals (Cr, Cu and Hg) in soils illegal mining sites Atiwa East District Ghana. The concentrations Copper (Cu), Chromium (Cr), Mercury (Hg) were determined using Atomic Absorption Spectrometry (AAS). extent metal risk assessment was analyzed site. Thirty (30) soil samples collected from three (3) within district. average levels Cu, Cr,...

OBJECTIVES To better define the relationship between dietary zinc and copper for humans so that sound recommendations for intakes of these elements can be made. METHODS A study was conducted to ascertain the effect of moderately excessive and deficient intakes of zinc on copper metabolism and use in humans fed low and luxuriant amounts of copper. Twenty-one postmenopausal women housed in a me...
