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...
15 صفحه اولHeterokaryon myotubes with normal mouse and Duchenne nuclei exhibit sarcolemmal dystrophin staining and efficient intracellular free calcium control.
Duchenne and mdx muscle tissues lack dystrophin where it normally interacts with glycoproteins in the sarcolemma. Intracellular free calcium ([Ca2+]i) is elevated in Duchenne and mdx myotubes and is correlated with abnormally active calcium-specific leak channels in dystrophic myotubes. We fused Duchenne human and normal mouse myoblasts and identified heterokaryon myotubes by Hoechst 33342 stai...
متن کاملA simulation study of calcium release channel
The IP3R calcium release channel has been simulated using a stochastic simulation algorithm (SSA;Gillespie algorithm) and De young-Keiser model. A set of different concentration for Cat' and IP3 havebeen used. Considering the Number of molecules in each state, a non linear behavior of the system can beseen clearly. The inhibiting role of the Ca+2 on the open state (X110) has been studied. The d...
متن کاملA Study on the Effects of Modulation of Intracellular Calcium on Excisional Wound Healing in Rabbit
An in vitro study on the role of intracellular calcium ions in healing of excisional wound in rabbit was undertaken. We employed two drugs namely, glibenclamide and nitroglycerin that are topically applied in vivo to modulate the activity of intracellular calcium. Our model consisted of a 15 ´ 15 mm excisional wound. Seven groups of New Zealand rabbits were used. The first three groups served a...
متن کاملIncreased calcium influx in dystrophic muscle
We examined pathways which might result in the elevated resting free calcium [( Ca2+]i) levels observed in dystrophic mouse (mdx) skeletal muscle fibers and myotubes and human Duchenne muscular dystrophy myotubes. We found that mdx fibers, loaded with the calcium indicator fura-2, were less able to regulate [Ca2+]i levels in the region near the sarcolemma. Increased calcium influx or decreased ...
