The vomeronasal organ (VNO), also know as Jacobson’s organ, is a paired chemosensory organ mediating the perception of chemical stimuli related to social and/or reproductive behavior (for review, see Farbman, 1992). In rodents, it is an elongated tube, with a crescentshaped sensory epithelium (SE) consisting of basal cells, bipolar neurons and supporting cells. Proliferation continues throughou...

Calcitonin was extracted from the ultimobranchial gland of salmon in quantities sufficient to permit purification and chemical characterization. The partially purified extract was subjected to gel filtration and ion exchange chromatography. Purification was monitored by bioassay of column e&tents against a standard prepared from the starting material. These methods led to detection of two chemi...

Because of the remarkable rate of restoration of liver tissue, the partially hepatectomized rat has been recognized as a useful preparation in which to study the process of active tissue growth (1-13) and the participation of various cellular components in this process (cf. (14)). However, the very early postoperative period, during which extreme fluctuations in liver constituents occur, has be...

BACKGROUND Nonalcoholic fatty liver disease (NAFLD) includes a group of chronic liver disorders caused by irregular accumulation of fat in liver tissue. The current study aimed to evaluate chemical composition and the effect of fruit extract and essential oil of Pimpinella anisum in experimental model of NAFLD. MATERIALS AND METHODS Sixty rats were randomly divided into ten groups, six in eac...

Herbal based remedies are used worldwide to treat psychiatric disorders. The aim of this study was to analyse the essential oil composition of Achillea Wilhemsii C. Koch (Asteraceae) and to evaluate its anxiolytic effects in the elevated plus maze (EPM) model of anxiety in rat. Gas chromatography/mass spectrometry (GC/MS) analysis of the essential oil showed that the main compounds of the oil w...

Mucus glycoproteins from newborn and adult rat small intestine were radiolabelled in vivo with Na2 35SO4 and isolated from mucosal homogenates by using Sepharose 4B column chromatography followed by CsCl-density-gradient centrifugation. Non-covalently bound proteins, lipids and nucleic acids were not detected in the purified glycoproteins. Amino acid, carbohydrate and sulphate compositions were...

Radiochemical and biochemical methods were used to characterize post-mortem and osteoarthrotic femoral head cartilage. Fixed charge density measurements were correlated with glycosaminoglycan content as estimated by uronic acid and hexosamine analyses. In post-mortem cartilage water content decreased from a maximum at the surface to a minimum in the deep zones. In the osteoarthrotic specimens ...

2. The nuclei in vitro incorporate [2-14C]glycine and [1-14C]valine into nuclear protein and [6-14C]orotic acid and [8-14C]adenine into nucleic acids. 3. Anoxia and 2,4-dinitrophenol inhibit the incorporation of the radioactive precursors into nuclear proteins and nucleic acids. Chlorpromazine inhibits the incorporation of valine, but has no effect on the incorporation of orotic acid. 4. The sp...

Bioactive compound from essential oils of Alpinia malaccensis (AM) and Kaempferia galanga (KG) rhizomes, respectively, such as methyl cinnamate ethyl-p-methoxycinnamate (EPMS) have been reported to anti-inflammatory activity. The present study aimed determine the topical activity 3 gel formulations (Formula 1, 2 3) having different concentrations oil AM KG rhizomes. gelling agent used in this w...

almabulage complex is located in the north of asadabad city, northwestern hamedan province, in sanandaj-sirjan structural zone. the complex includes several types of low-grade metamorphosed rocks with various protoliths as well as two intrusion having different chemical compositions of synogranite and gabbro. the synogranite intrusion rock has perthite and granophyric co-growths textures and au...
