In the present study, the existence of serotonin immunoreactivity was investigated in the adrenal gland and kidney of porcupine, Hystrix cristata, using immunohistochemical techniques as a pioneer attempt. Serotonin immunoreactivity was detected in adrenal medullary cells, distal tubules and collecting duct cells in kidney.

Laboratory-raised Northeirn blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependenit upon the motivational state of the jay and the presence of food pellets.

BACKGROUND Celosia cristata Linn. (Amaranthaceae) is used in traditional medicine for the treatment of headache, sores, ulcers, eye inflammations, skin eruption, painful menstruation and carpal tunnel syndrome. This study was performed to evaluate the antinociceptive activity of methanol extract of the whole plant of C. cristata (MECC). METHODS The evaluation of the antinociceptive effect of ...

Abstract Background Species of Sarcocystis are parasitic protozoa in poikilothermic and homeothermic animals. Out the 26 valid species birds as intermediate hosts, none has been reported those order Musophagiformes, such great blue turaco Corythaeola cristata (Vieillot, 1816), which is a bird endemic to Central Western Africa. The examination turacos imported from Africa Republic Czech allowed ...

The twenty species of Scleractinia (all azooxanthellate) known to occur off Argentina and the Falkland Islands (the At lantic component of the cold temperate Magellan Province) are discussed, 15 of which are documented by new records Five new species are described: Caryophyllia kellerae, C. coronula, Solenosmilia australis, Flabellum cinctutum, and Ja vania cristata. Five geographic and nine ba...

Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone, 1), known as a host-specific attractant towards the zoospores of Aphanomyces cochlioides, a cause of root rot and damping-off diseases of Chenopodiaceae, was found in the Amaranthaceae plant, Celosia cristata, that is susceptible to the pathogen. The content of 1 in Celosia seedlings was quantified as 1.4 microg/g fresh weight. A new isoflav...

Celosia cristata is one of the floricultural commodities which also beneficial as a medicinal plant. Mutation techniques can effectively increase morphological diversity and biochemical content C. cristata. Chronically induced mutation using ethyl methane sulfonate (EMS) was first applied to properties. This study proposes modifying induction technique that allows plant material be exposed muta...
