Isoproterenol is a potent B-adrenergic agonist which its effect on rabbit salivary Glands has been studied in this research.two groups of male albino rabbits(five in each group with the mean weight of 1000+_300 gr) were injected with 20 mg/kg of  isoproterenol intrapritoneally each day for fifteen days and one similar group(n=5) was chosen as control group.in one of the test groups in addition ...

the aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in dunaliella salina teod. the algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 m nacl under three illumination regimens [4500 (control), 9000 and 11000 lux]. the results showed that most electrophoresis protein bands were separa...

allergy to prosopis juliflora (mesquite) pollen is one of the common causes of respiratory allergy in tropical countries. mesquite is widely used as street trees in towns and ornamental shade trees in parks and gardens throughout arid and semiarid regions of iran. the inhalation of mesquite pollen and several species of amaranthus/chenopodiaceae family is the most important cause of allergic re...

copper is most toxic metal in marine organisms. characterization of protein occurring in the metabolically active tissues of muscle (mu), hepatopancreas (hp) and gills (gl) of the spiny lobster, panulirus homarus homarus on exposure to two sub-lethal doses (9.55 and 19.1 µg/l) of copper were studied for 28 days of exposure (doe). the electrophoretic pattern of muscle, hepatopancreas and gill pr...

One of the mainly popular consumed colloid protein materials in pharmaceutics, medical, food and military industries is Gelatin. Especially from warm-water fish gelatin report poss similar characteristics to mammalian’s gelatin .Yellow fin tuna (Thunnus albacares) gelatin skin, lots of waste in form of skin and bones of the fish are produced every day. Analysis factors were extracted alkaline g...

Mastitis is one of the most important diseases of dairy cattle in the world. The identification and characterization of the constituent proteins in milk can be useful for studying the biochemistry and pathogenesis of mastitis. In this study, the electrophoretic patterns of milk from 10 healthy and 30 mastitic cows were studied. All of the latter milk samples were California Mastitis Test (CMT) ...

abstract: cryptosporidium parvum is an apicomplexan protozoan parasite which causes diarrhea in both human and wide range of animals. since this protozoa causes remarkable economic losses in cattke industry in iran, the molecular determination of porotozoa and characterization of its protein pattern and immunogenic antigend are the aim of this study. in this study, diarheatic fecal samples of c...

1. The absorption spectra of a number of proteins in the region 2500 to 3000 A. have been found to comprise from six to nine narrow bands. In consequence of variation in the relative intensity of these bands from protein to protein, the absorption curve has a characteristic configuration for each protein. 2. These bands correspond closely in position with the narrow bands which appear in the ab...
