Levosulpiride is the levo-enantiomer form of racemic sulpiride, a benzamide derivative selectively inhibiting dopaminergic D_2 receptors at the trigger zone both in the central nervous system and in the gastrointestinal tract. The purpose of the present study was to evaluate the bioequivalence of two levousulpiride tablets. Levopride (SK Pharmaceutical Co. Ltd.) and Levopid (Dae Won Pharmaceutical Co. Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). The levosulpiride release from the two levosulpiride tablets in vitro was tested using KP Ⅶ Apparatus Ⅱ method with various different kinds of dissolution media (pH 1.2, 4.0, 6.8 buffer solution and water). Twenty eight normal male volunteers, 23.82 ±3.26 years in age and 69.13 ±8.58 ㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After one tablet containing 2.5 ㎎ of levousulpiride was orally administered, blood was taken at predetermined time intervals and the concentrations of lovosulpiride in serum were determined using HPLC method with fluorescence detector. The dissolution profiles of two levosulpiride tablets were very similar at all dissolution media. Besides, the pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed AUC_t, and C_max and untransformed T_max. The results showed that the differences in AUC_t, C_max and T_max between two tablets based in the Levopride were -1.17%, 1.20% and -1.09%, respectively. There were no sequence effects between two tablets in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.25) (e.g., log(0.93)∼log(1.07) and log(0.90)∼log(1.14) for AUC_t and C_max, respectively). The 90% confidence interval using untransformed data was within ±20% (e.g., -19.47 ∼16.20 for T_max). All parameters met the criteria of KFDA guideline for bioequivalence, indicating that Levopid tablet is bioequivalent to Levopride tablet.

The photodegradation of phenol and toluene with the Ti0₂-coated polyethylene (PE) particles were investigated in the slurry type photocatalytic reactor, changing the Ti0₂ particle sizes, initial phenol and toluene concentrations, and the oxygen flow rate. The nano-sized Ti0₂ photocatalyst particles were prepared by the diffusion flame reactor and they were coated onto PE particles by using the hybridization system for the efficient recollection of Ti0₂- coated particles after photodegradation experiments. The degradation efficiencies of phenol and toluene with the Ti0₂-coated PE particles were more than 90% after photodegradation of 80 minutes for most cases. The efficiencies of photodegradation with the Ti0₂-coated PE particles were found to be lower than those by the pure Ti0₂ particles by 50%, because of the decrease in specific surface area of Ti0₂ particles in PE particles.

The recombinant pseudorabies virus major capsid protein (rMCP) was produced by expression of the MCP gene in Sf-9 cell using baculovirus transfer vector system. Following evaluation of the immunochemical properties of the rMCP, the immunogenicity of the recombinant subunit protiens were investigated in guinea pig and swine to obtain the preliminary guide line for the subunit vaccine using rMCP and gP50. It was proved that ultrasonication and 30% ammonium sulfate was most efficient to concentrate and purify the protein. The rMCP was safe in mice, guinea pigs and piglets. In guinea pigs, rMCP mixed with various adjuvants induced substantial degree of serum neutralizing antibody titers, but revealed incomplete protecivity against challenge. In swine, the combination of rMCP and gP50 showed the higher serum neutralizing antibody titers and cellular immune responses than rMCP alone. However, the protectivity was lower in comparison with the commercial gI-deleted inactivated vaccine. We expect these results to contribute to characterization of MCP gene of Korean isolate of PRV and to ultilize as preliminary information for prodution and evaluation of PRV recombinant subunit vaccines.
