objective in previous studies, the relaxant, anticholinergic (functional antagonism), antihistaminic and its stimulatory effects on b-adrenoceptors of nigella sativa have been demonstrated on guinea pig tracheal chains. in the present study, the relaxant effects of hydro-ethanolic, macerated aqueous (ma) and lipid-free macerated aqueous (lfma) extract of nigella sativa on tracheal chains of gui...

background and purpose: generated dye wastewater by the textile industry is usually toxic, non-biodegradable and resistant in the environment. eggshell is one of the inexpensive material and for the reason the vesicular structures can be used as a proper adsorbent for pollutants removal. the aim of this study is to investigate the efficiency of eggshell for removal of acid orange 2 dye from aqu...

background: phenol is an organic pollutant found in industrial effluents that is very toxic to humans and the environment. this study used pomegranate peel ash as a natural absorbent to remove phenol from aqueous solutions. methods: in this study, pomegranate peel ash in different doses was used as a new adsorbent for the removal of phenol. the effects of contact time, ph, adsorbent dose and in...

background : textile wastewater is the most important pollutant of the environment. navy blue (nb) ce-rn is an important chemical dye widely used in the textile industry. the present study aimed to investigate the removal of nb textile dyes from aqueous solutions using magnetic iron oxide absorbents. methods: in this study, a sample of synthetic wastewater with nb concentration of 50 mg/l was u...

Antibiotics such as fluoroquinolones (FQLs) are commonly used to treat ocular infections but are also known to cause dermal melanocyte toxicity. The release of dispersed pigments from the iris into the aqueous humor has been considered a possible ocular side effect of the systemic administration of FQLs such as Moxifloxacin, and this condition is known as bilateral acute iris transillumination ...

forty patients with cataracts, as well as 40 patients with proven ocular toxoplasmosis were enrolled in this prospective clinical study. serum igg and aqueous igg in both groups were measured by enzyme-linked immunosorbent assay (elisa) and the corresponding ratios were calculated. serum igg/aqueous humor igg ratio was less than 100 in the patient group and more than 100 in the control group. o...

background: contamination of water with arsenic has attracted the researchers’ attention as a global problem in recent years and has been observed in some parts of iran. the purpose of this study is to assess the efficiency of welding iron waste in removing arsenic from aqueous solutions.   methods: in this study, the effects of different parameters, such as ph (3-9), initial concentration of a...

Purpose. To evaluate aqueous humor MMP-9 levels in alkali-burned rabbit cornea following KPr implantation and their roles in RPMs formation. Methods. Left eyes of 36 rabbits received a deep corneal alkali wound. 12 corneas were implanted with KPro and the other 24 control corneas were either penetrating keratoplasty or left without keratoplasty. Aqueous humor MMP-9 and TIMP-1 levels were determ...

Oh, J. O. (University of British Columbia, Vancouver, B.C., Canada), and E. J. Gill. Role of interferon-like viral inhibitor in endotoxin-induced corneal resistance to Newcastle disease virus. J. Bacteriol. 91:251-256. 1966.-A state of marked resistance to the toxic corneal effects of Newcastle disease virus (NDV) was observed in rabbit eyes after intravenous injection of 10 or 100 mug of typho...
