b-chain shortening of matrix-bound insulin with pepsin, ii. preparation and properties of camel des-pentapeptide (b26-30)- and des-pheb1-des-pentapeptide (b26-30)- insulin.digestion of matrix-bound camel insulin with pepsin was found to be restricted to the cleavage of the peptide bond between phenylalanine(b25) and tyrosine(b26). purification of the camel des-pentapeptide(b26-30)-insulin obtained was achieved by gel filtration and ion exchange chromatography, yielding a molecularly uniform product. in the same way, camel des-pheb1-insulin prepared according to a method described for bovine insulin was hydrolyzed with pepsin and purified to give the des-pheb1-desp ...19751100508

male meiosis in camel-flies (raphidioptera; neuropteroidea).male meiosis in 3 species of the raphidioptera genus agulla-- a. bicolor banks, a. astuta (banks), and a. bractea carpenter-- closely parallels that of neuroptera. the diploid complement in each comprises 12 pairs of autosomes plus x and y; all are mediokinetic. one male of a. bicolor carried an extra pair of autosomes indistinguishable from the shortest member of the usual set: these formed a normal bivalent and segregated synchronously with the other autosomes. the spindle is formed by the col ...19751140044
effects of dehydration on body-water distribution in desert kangaroos.the effect of dehydration on the distribution of water in the bodies of two species of desert kangaroos, the red kangaroo megaleia rufa and the euro macropus robustus, has been examined. the volumes of various body-fluid compartments were determined in normally hydrated animals and then after the kangaroos had been dehydrated until body weight declined to 80% of the initial weight. the fluid compartments examined were total body water, plasma volume, intracellular volume (cellular and gut water) ...19751147052
relationship and possible function of the nasal sacs and glands of the one-humped camel, camelus dromedarius.the relationship between the lateral nasal gland and sacs of the maxillary recesses was investigated. the nasal sacs possess a well-defined aperture communicating with the nasal cavities. it was concluded that the sacs and not the body of the gland produce mucous secretions that moisten the inhaled dry air of the desert and may also act as reservoirs. a possible function of the body of the nasal gland is water economy by excretion of concentrated salts.19751155005
carotid body of camelus dromedarius.the carotid body of the camel is located between a mass of loose connective tissue at the point of separation of the internal carotid artery from the carotid trunk. a capsule-like connective tissue sheath sends strands in between the parenchyme of this organ and separates lobes and lobules, making it disseminated in type, as in man and in the horse. two distinct types of cells were found in the parenchyma. type i cells with specific electton-dense, cored vesicles, and type ii cells with protopla ...19751163190
epidemiological and clinical aspects echinococcosis in east iran.three hundred and fifty two cases of hydatid disease were diagnosed in a three year study in eas iran, where the disease is found frequently in rural areas. camel meat is consumed in this region. the offal is given to domestic carnivorous animals, for example sheep dogs, and in these circumstances camels could contribute to the cyclozoonotic spread of the disease. clinical symptoms are briefly mentioned.19751165584
