The effect of different surface preparation methods such as mechanical, chemical and electrochemical surface preparation on the formation, stability and deterioration of surface films formed on austenitic 304 stainless steel was investigated in Tyrode’s physiological solution by cyclic polarization curves, AC impedance measurements surface techniques. A hysteresis loop in a cyclic polarization ...
Factors affecting the circulation of haemopoietic stem cells (CFU) in the peripheral blood of mice were investigated. I.v. injection of sublethal doses of endotoxin, trypsin and proteinase appeared to raise the number of CFU per ml blood from about 30-40 to about 300-400 or more within 10 min. The effect was smaller when smaller doses of the substances were injected. After this initial rise the...

In comparison of effects of various drugs with the same indications produced by different companies or comparing drugs manufactured in Iran with their foreign counterparts may result in producing drugs with higher qualities in our country. In this study the spasmolithic effect of two herbal drugs , gripe mixture and caraway mixture , that are prescribed as spasmolithic ...
هدف از این تحقیق ارزیابی اثرات عصاره تام متانولی گیاه سرخاب کولی (Phytolacca decandra L.) بر روی قلب ایزوله رت نر و اختصاصاً اثرات این عصاره بر روی خواص الکتروفیزیولوژیکی گره دهلیزی- بطنی بود. قلب رت نر پس از خارج شدن تحت انفوزیون Antrograde با محلول تیرود (Tyrode) قرار گرفته و با استفاده از روشهای الکتروفیولوژیکی کلیه پارامترهای الکتریکی قلب از قبیل ثبت از دهلیزها، ثبت از بطنها، ثبت از نیروی ...
background and aims: the antioxidant and anti-inflammatory effects of carvacrol were reported. the aim of the current study was an investigation the relaxant effects of carvacrol on acetylcholine-induced contraction in isolated rat's ileum. materials and methods: in this study, the tissues separated from ileum were fixed on the organ bath containing tyrode's solution. the amplitude of...
Extracts of homologous adult tissues detemine an increase in the mass of pure cultures of chicken fibroblasts nourished thereon comparable to that resulting from embryonic tissue juice. But the effect of these extracts differs markedly from that of the latter, since cell multiplication does not continue indefinitely. After a few passages, the fibroblasts cultivated in adult tissue extracts grew...
Background: The effects of cholinergic system are applied through both nicotine and muscarinic receptors. Considering to muscarinic receptorsexistence in therat ileum, in this researchthe effectof carbachol (muscarinic receptor agonist) and scopolamine (muscarinic receptor antagonists) on the ileum contraction induced by KCl in adult male rats were studied. Materials and Methods: The distal pa...
Introduction:The licorice (Glycyrrhizaglabra) rhizome has been widely used in traditional medicine for treatment of gastrointestinal diseases such as gastric ulcer and relieve intestinal spasms. In the present study, the effect of hydro-alcoholic extract of licoricerhizome on mechanical activity of isolated colon of male rats has been studied. Methods: Adult male rats were anesthetized by et...
We investigated vascular reactivity in isolated, Tyrode perfused kidneys from male (blood pressure, 222.6 mm Hg) and female (blood pressure, 178.5 mm Hg) spontaneously hypertensive rats (SHR, 4-6 months age) and sex and weight matched normotensive Kyoto Wistar and Wistar control rats. Optimal perfusion flows and basal pressures were similar in sex-matched SHR and control rats. Subraaximal const...
