a pot experiment in randomized complete blocks design (rcbd) with six treatments in four replications was conducted to study the effect of water stress on morphological characteristics and essential oil content of improved basil (ocimum basilicum c.v. keshkeni luvelou). the irrigation treatments for induction of water stress were: a: (125 ml/ 12 h), b: (250 ml/ 24 h), c: (250 ml/ 48 h), d: (500...

UNLABELLED Hydroxyethyl starches (HES) are almost exclusively excreted glomerularly, in part after hydrolysis by amylase. HES 130/0.4 (Voluven; Fresenius Kabi Deutschland GmbH, Bad Homburg, Germany) was developed to improve pharmacokinetics whereas preserving the efficacy of volume effect. We studied the dependency of pharmacokinetics of HES 130/0.4 on renal function. Nineteen volunteers with s...

Two experiments were conducted to evaluate the effects of eCG, temporary 72-h calf removal (CR), or both on dominant follicle (DF) diameter and pregnancy rates (PR) in suckled beef cows. For Exp. 1, we hypothesized that CR, eCG, or both at PGF2α administration concomitant with synchronization of ovulation protocol would increase DF diameter and alter patterns of LH, estradiol (E), and progester...

Glutamine synthetase (GS), as measured by its 7-glutamyl transferase (GT) activity ~, can be precociously induced in chick embryo retinas in tissue culture at least 7 days before its normal rapid elevation in o v o (Reif-Lehrer, 1968). The enzyme can be induced by a number of glucocorticoids (Chader and Reif-Lehrer, 1972), cortisol being the one most commonly employed. In such experiments , the...

The influence of varying doses of human chorionic gonadotropin (hCG) on the preovulatory luteinizing hormone (LH) surge, estradiol-17 beta (E2) and progesterone (P4) was studied in synchronized gilts. Altrenogest (AT) was fed (15 mg X head-1 X d-1) to 24 cyclic gilts for 14 d. Pregnant mares serum gonadotropin (PMSG; 750 IU) was given im on the last day of AT feeding. The gilts were then assign...

A single dose of the apolipoprotein (apo)A-I mimetic peptide D-4F rendered high-density lipoprotein (HDL) less inflammatory, motivating the first multiple-dose study. We aimed to assess safety/tolerability, pharmacokinetics, and pharmacodynamics of daily, orally administered D-4F. High-risk coronary heart disease (CHD) subjects added double-blinded placebo or D-4F to statin for 13 days, randoml...

Background: Watermelon is a rich natural source of l-citrulline. This non-essential amino acid increases exercise performance. Objective: Evaluate the effect of Fashion watermelon juice enriched in l-citrulline (CWJ) (3.45 g per 500 mL) in physical performance and biochemical markers after a half-marathon race. Design: A randomised, double blind, crossover design where 2 h after drinking 500 mL...

Systemic anthrax manifests as toxemia, rapidly disseminating septicemia, immune collapse, and death. Virulence factors include the anti-phagocytic gamma-linked poly-d-glutamic acid (PGA) capsule and two binary toxins, complexes of protective antigen (PA) with lethal factor (LF) and edema factor. We report the characterization of LF, PA, and PGA levels during the course of inhalation anthrax in ...

BACKGROUND The aim of this study was to evaluate the course of hemoglobin (HGB) concentration and hematocrit (HCT) in donor blood during and after preparatory plasmaphereses (PP) without NaCl and with an infusion of 500 ml 0.9% NaCl during PP. METHODS After informed consent 32 plasma donors were studied in a crossover design. They underwent PP once without NaCl infusion and once, on a differe...

The aim of this study was to characterize the effect of typhoid fever on pharmacokinetic parameters of levofloxacin (LF) and compare the pharmacokinetic parameters of the said antibiotic in healthy human volunteers and patients with typhoid fever. Total of 12 subjects were divided into two groups “A” (healthy volunteers) and “B” (typhoid patients). Single oral dose of LF 500 mg was given and 5 ...
