In fabricating plasma display panels, the photolithographic process is used to form patterns of barrier ribs with high accuracy and high aspect ratio. It is important in the photolithographic process to control the refractive index of the photosensitive paste. The composition of this paste for photolithography is based on the $B_2O_3-SiO_2-Al_2O_3$ glass system, including additives of alkali oxides and rare earth oxides. In this work, we investigated the density, structure and refractive index of glasses based on the $B_2O_3-SiO_2-Al_2O_3$ system with the addition of $Li_2O$, $K_2O$, $Na_2O$, CaO, SrO, and MgO. The refractive index of the glasses containing K2O, Na2O and CaO was similar to that of the [BO3] fraction while that of the SrO, MgO and Li2O containing glasses were not correlated with the coordination fraction. The coordination number of the boron atoms was measured by MAS NMR. The refractive index increased with a decrease of molar volume due to the increase in the number of non-bridging oxygen atoms and the polarizability. The lowest refractive index (1.485) in this study was that of the $B_2O_3-SiO_2-Al_2O_3-K_2O$ glass system due to the larger ionic radius of $K^+$. Based on our results, it has been determined that the refractive index of the $B_2O_3-SiO_2-Al_2O_3$ system should be controlled by the addition of alkali oxides and alkali earth oxides for proper formation of the photosensitive paste.

<P>The colibacillosis caused by avian pathogenic <I>E. coli</I> (APEC) is responsible for a significant loss of productivity and mortality in the poultry industry. The pathogenicity of these bacteria is based on the presence and expression of various virulence factors. In this study, the presence of the 19 virulence-associated genes in APEC was determined using PCR. Among the 118 <I>E. coli</I> isolates from the chickens with colibacillosis, all contained at least one of the 19 genes as approximately 95% of the isolates contained <I>fimC.</I> Interestingly, the <I>clpG</I> gene, which has not been detected in APEC previously, was detected in half of the isolates. The ColV plasmid-associated genes such as <I>colV, tsh, iucC, iucD and iss</I> genes were also detected in 57.6, 55.9, 50.0, 47.5, 47.5 and 41.5% of isolates, respectively. With regard to the fimbrial genes, the <I>papA</I> (14.4%), papC (14.4%) and <I>papG</I> genes (15.2%) were identified at relatively low rates, none of the isolates harbored <I>afa8D, f17A</I> or <I>facA</I>, and only 3 of the isolates (2.5%) contained <I>eaeA.</I> In this study, 94 isolates harbored two or more of the genes, and there were 43 different patterns of gene combination in the isolates. The most common pattern, which was found in 14.4% (17 isolates), was <I>clpG-fimC-iutA-colV-tsh-iucC-iucD-irp2-fyuA-vat-iss.</I> Overall, these results suggest that APEC strains in this area commonly contain multiple virulence factors and approximately half of the APEC strains contained the ColV plasmid-associated genes. Especially, <I>colV</I> and <I>tsh</I> were detected more than half of the isoaltes.</P>

So-Hap-Hyang-Won, a traditional oriental medicine used in the treatment of stroke patients, was examined for its ability to reverse the cell damage caused by lipid peroxidation products and oxidative stress in bovine aortic endothelial cells (BAEC). The effects of herbal medicine on cell proliferation and recovery of oxidative damaged situation were studied in BAEC, which was considered an appropriate in vitro model for stroke resulting from various vascular diseases prevalent in advanced age. In a clinical study of stroke patients, So-Hap-Hyang-Won appeared to improve considerably arm and leg movements as well as consciousness disturbance condition, compared with other traditional medicines used for stroke. When BAEC were treated with extracts of the lyophilized herbal medicines, only that of So-Hap-Hyang-Won stimulated cell proliferation and showed no toxicity even at high concentrations. In studies of BAEC treated with extracts of the lyophilized material of the 14 components of So-Hap-Hyang-Won, only the extract of Foeniculi Fructus stimulated cell growth at all concentrations tested. Moreover, when cells were treated with Foeniculi Fructus (10 and 100 mg/ml) extract after prior exposure to t-BHP ($l0\mu\textrm{M}$) or HNE ($0.2\mu\textrm{M}$), lipid peroxidation products which are known to be involved in aging and vascular diseases, or after the exposure to SIN-l ($500\mu\textrm{M}$), which generates nitric oxide (NO) and other reactive oxygen species, there was substantial recovery from the oxidative damage, presumably due to the radical-scavenging effect of Foeniculi Fructus extract. Foeniculi Fructus not only showed stimulatory effects on cell growth and cell damage repair in BAEC, but also appeared to show the most anti-aging activity among all the herbal components of So-Hap-Hyang-Won.
