Adaptability is probably the most distinct characteristics of life which may be defined as sum of all nonspecific response of the body to any demands made upon it; fundamentally it was a physiological response; primary object of which was to maintain life and to re-establish the normal state. Analgesic and Immunomodulator activity of leaves of Artocarpus heterophyllus Lam. was evaluated by usin...
The study was designed to investigate analgesic and antipyretic activities of petroleum ether and alcohol extracts of Centratherum anthelminticum (L) Kuntze (family: Asteraceae) seeds (100 and 200 mg/kg, p.o.) in brewer's yeast-induced fever model in rats, acetic acid-induced writhing and Eddy's hot plate methods in mice. Both petroleum ether and alcohol extracts showed significant decrease in ...
This manuscript describes a new protocol for determination of Pa/Th/U in marine sediments. It is based on microwave-assisted digestion and represents an important reduction of working time over conventional hot-plate digestion methods, and the use of HClO(4) is avoided. Although Th and U are completely dissolved with a first microwave step, around 40% of (231)Pa remains undissolved, and a short...
The objective of this study was to evaluate the anti-inflammatory and analgesic activities of the hydro-alcoholic extract of the pods of Astragalus hamosus (HAAH), a plant used in Iranian traditional medicine, and antinociceptive effects of different fractions in animal models. The anti-inflammatory effect was evaluated by the rat paw edema induced by formalin. Also the analgesic effect was exa...
The effects of combined exposure to n-butyl alcohol and n-butyl acetate on rotarod performance and hot plate behaviour in rats and respiratory rate in mice were investigated in the condition of an acute inhalation experiment. Rotarod performance and hot-plate behaviour were tested in rats exposed to various concentrations of n-butyl alcohol, n-butyl acetate and their mixture consisting of 50 Vo...
The analgesic activity of ethanolic extract of Justicia beddome leaves (Family: Acanthaceae) was evaluated in albino rats using Eddy's hot plate method. The extract at 50 and 100 mg/ kg, (i.p), showed significant analgesic activity at 90 minutes of administration. The analgesic effect of the extract was comparable to that of morphine sulphate.
A colorimetric method for arsenic in urine utilizing a portable hood and requiring minimal laboratory facilities is described. Urine samples are combusted in a hot plate-oven with MgO and Mg(No3)2. Arsine is generated from the ashed product and passed into silver diethyldithio-carbamate in pyridine. Inorganic and organic arsenicals in urine at 0.03 ppm with 6% variation is detectable.
سابقه و هدف: با توجه به اثر ثابت شده ضد درد مرفین و نتایج مغایر حاصل در ارتباط با نقش گیرنده های cck در پدیده درد و از طرفی، نقش جراحی و گره زدن عصب سیاتیک (nerve ligation) به عنوان عامل ایجاد کننده درد و هیپرآلژزی که موجب کاهش پاسخ به داروهای ضد درد اوپیوئیدی می شود. از این رو، به منظور تعیین تاثیر بستن عصب سیاتیک بر روی بی دردی ناشی از مرفین، همچنین آگونیست گیرنده های cck این تحقیق در سال 77-...
In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...
