Plasma Emission Spectrometry: Measurement of Calcium, Phosphorus and Chromium in Metabolic Balance Studies

the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...

Attosecond emission from chromium plasma.

We present the first measurement of the attosecond emission generated from underdense plasma produced on a solid target. We generate high-order harmonics of a femtosecond Ti:sapphire laser focused in a weakly ionized underdense chromium plasma. Using the "Reconstruction of Attosecond Beating by Interference of Two-photon Transitions" (RABITT) technique, we show that the 11th to the 19th harmoni...

Effect of dietary calcium and phosphorus level upon calcium, phosphorus and nitrogen balance in swine.

A comparison of chromium sesquioxide and [51Cr]chromic chloride as inert markers in calcium balance studies.

1. Chromium sesquioxide (Cr2O3; 1.5 g/day) and [51Cr]chromic chloride [51CrCl3 (0.3 muCi/day)] were compared as continuously administered non-absorbed markers for the correction of faecal recoveries in 14 calcium balance studies each lasting at least 18 days. 2. The mean recoveries of each, 98.4% for Cr2O3 and 101.9% for 51CrCl3, were not significantly different from 100%. 3. The two markers re...

Studies of Calcium Metabolism in Multiple Myeloma with Calcium and Metabolic-balance Techniques.

Despite the fact that approximately 90% of patients with multiple myeloma present themselves with skeletal complaints (1, 2), few studies of bone mineral metabolism in this disease have been reported. Stable calcium studies in multiple myeloma were first reported in the literature by Blatherwick (3) in 1916. Since that time there have been only infrequent reports using balance techniques, or is...
