The survival of thyroid allografts in mice was prolonged by either holding the grafts in vitro culture for 20 to 27 days or by cobalt-60 irradiation of the donor 2 days before transplantation with or without the intravenous injection of colloidal carbon just before removing the thyroid from the donor. In both cases the rejection process was restored by an intravenous injection of recipients wi...

The pharmacokinetics of ceftriaxone were investigated in six healthy adults. One-gram doses were administered either intramuscularly or intravenously in a crossover design study. Mean peak ceftriaxone concentrations in plasma of 79.2 and 123.2 micrograms/ml were achieved with intramuscular injection and intravenous infusion, respectively, with plasma half-lives of 5.4 and 5.8 h. The urinary rec...

Regional lung function using xenon-133 was studied in 45 seated patients aged 11 to 78 years with untreated idiopathic scoliosis and angulation of curvature between 10 and 1900. Perfusion distribution was assessed by intravenous bolus injection of '33Xe and distribution of ventilation to volume ratios by washouts after inhalation and intravenous injection. No consistent differences between the ...

BACKGROUND The challenge in providing analgesia for spine surgeries is to provide extended postoperative pain relief and simultaneously allow early neurological assessment and mobilization. Our study aimed to evaluate the analgesic efficacy of intravenous versus caudal dexamethasone in lumbosacral spine surgeries. MATERIALS AND METHODS In this prospective double-blind study, a total of 96 pat...

The level of plasma radioactivity following a single intravenous injection of (131)I-labelled sodium orthoiodohippurate (radiohuppuran) falls with time in a tri-exponential fashion. The rate of fall of plasma radioactivity after an intravenous injection of radiohippuran was measured over the period 25 to 40 minutes from the time of injection and was expressed as the half-life of radiohippuran. ...

This study was done in an effort to improve the intravenous dye injection technique used in fluorescent indocyanine green and sodium fluorescein dye angiography of the eye. The concentrations of these two dyes in blood at which maximum fluorescence occurs were determined, and methods of achieving these concentrations in the ocular vasculatures via cubital vein injection were investigated. The e...

 Abstract Background: Providing better surgical conditions with meticulous control of Intraocular Pressure (IOP) is one of the most important factors that affect the success rate in ophthalmic surgery. Clonidine is a selective central α2 agonist with analgesic, antianxiety and sedative effects which makes it a good choice in premedication recently. In this study, we compared the effects of oral...

A decrease in arterial oxygen saturation (Sao2) has been observed to follow intravenous aminophylline administration in patients with chronic pulmonary disease (Halmagyi and Cotes, 1959). The decrease in Sao2 occurred 40 minutes or more after the injection in a group of patients who had shown an increase in maximum breathing capacity (M.B.C.) in response to the drug. The onset of symptomatic re...
