The formation of tretinoin-PEG 6000 solid-solid solution to increase the dissolution rate of tretinoin

The formation of solid-solid dispersion of tretinoin which is insoluble in water into water soluble carrier PEG, might accelerate solubility and dissolution rate. The objectives of this study were to obtain dissolution profile and physical properties of Tretinoin-PEG solid dispersion which was prepared by solventfusion method, to obtain the composition of Tretinoin and PEG in which produce solid dispersion with optimum dissolution rate and to obtain the composition of Tretinoin-PEG, which produce an interstitial solid-solid solution. Solvent fusion method at low temperature was choosen to prepare the solid dispersion system. The physical state of formed solid dispersion was determined by X-Ray diffractometer. To unveil the information about the solubility and dissolution rate of tretinoin, a test toward the dissolution rate of tretinoin was performed into the dissolution medium phosphate buffer. The X-Ray diffractogram of tretinoin-PEG solid dispersion in all composition indicated that tretinoin hasformed a molecular dispersion in the PEG crystals in all composition. In solid dispersion was obtained by solvent-fusion method in molecular or in solid-solid solution. Dissolution efficiency (DE) value prooved that molecular dispersion of tretinoin-PEG could increase the dissolution rate of tretinoin. Thus it could concluded that in comparison to the tretinoin and its physical mixture, the solid dispersion of tretinoin-PEG led the higher dissolution rate and the optimum rate was achieved by composition of 1=100 with DE value = 74.Key words : Tretinoin, PEG, Solid Dispersion, Dissolution Rat

Serologi dan virologi virus avian influenza H5N1 pada kucing jalanan di Kota Bogor

Highly  pathogenic avian influenza (HPAI) H5N1 virus is a known pathogen in birds. Recently, the virus has been reported to cause sporadic fatal disease in tigers, leopards, and other exotic felids as well as domestic cats  in Thailand. The present study was carried out to investigate the presence of AI H5N1 virus infection in stray cats roaming around residential, traditional and chicken farms in Bogor, West Java. Ninety serum samples were tested using HI test to screened for the presence of antibody to AI H5N1. Virus isolation was done in SPF embrionated chicken eggs and identify using HI, AGP and RT-PCR. The results showed that 18,9% of stray cats developed antibodies against H5 with geometric mean titre 23,1 . Stray cats lived in traditional markets 18–40% developed antibodies in the titre ranging from 22,8  to 24,5. Only two out of nine stray cats which lived in chicken farm developed low antibody titres again H5 (21). None of the stray cats lived in residencial area have developed antibodies against H5. This study revealed that stray cats have been contact with AI H5. Avian influenza H5 viruses were isolated in eight out of 33 pooled of rectal swab samples. The viral cleavage site sequences are CCTCAAAGAGAGAGC AGAAGAAAGAAGAGAGGT which represent amino acid sequences of PQRESRRKKRG. Based on the cleavage site sequence, the isolates are similar with the AI H5 virus subtype isolated from human in Indonesia during 2005–2007

Extrahepatic bile duct ligation in broiler chickens: ultrastructural study of Ito cell

The Ito cell (fat-storing cell) is a cell lying in perisinusoidal space of liver. The function of Ito cell is expanding from a site of fat-storing site to a center of extracellular matrix metabolism and mediator production in the liver. This study was performed in order to evaluate the Ito cells in cholestatic condition. The artificial cholestatic was conducted by ligation of extrahepatic bile ducts (bile duct ligation = BDL) in broilers. The results showed that BDL induced bile congestion, fibrosis, proliferation of Ito cells and intrahepatic bile ductules. Immunohistochemistry demonstrated that Ito cells were scattered throughout the fibrotic areas, and larger in size with more extensive immunoreactivity than those in normal livers. Ultrastructural study demonstrated that Ito cells were closely associated with the production of extracellular collagen fibers. Ito cells actively react against hepatocytic injuries, especially in fibrogenesis of cholestatic livers.   Key words: Bile duct, ito cell, broile
