In order to evaluate the neutral red uptake assay as an alternative method for phototoxicity test, we compared the potential of phototoxicity in vitro in cultured human fibroblasts and 3T3 fibroblast cells derived from Balb/c mice. Both fibroblasts were exposed to various known phototoxic chemicals (promethazine, neutral red, chlorpromazine, chlortetracycline, amiodarone, bithionol, 8-methoxypsoralen) and non-phototoxic chemical (ammonium laureth sulfate) and irradiated with 5 J/cm$^2$ of UVA.(omitted)

The objective of this collaborative study was to establish a Korean standard of Japanese encephalitis (JE) vaccine (mouse brain-derived, formalin-inactivated) for potency assay. A candidate preparation proposed as a Korean standard was provided by GreenCross Vaccine, and six laboratories, including one national control laboratory and five manufacturers of JE vaccine, participated in the study. The potency of the candidate preparation and a reference standard obtained from Japan was estimated by mouse immunogenicity assay using the in vitro plaque reduction neutralization test (PRNT). The results of 72 assays conducted by the 6 laboratories showed that the overall mean potency estimate of the candidate preparation was 2.455 log median plaque reduction neutralization antibody titer per 0.5-ml dosage administered twice in mice at 7-day intervals, and that the mean potency ratio of the candidate preparation relative to the reference standard was 1.074. The potency estimates were quite variable among laboratories irrespective of the preparation. The variability of assays assessed by Z scores and coefficient of variation (CV) were in general within the level of acceptance (Z scores within $\pm3$ and $CV\;\leq\;15%$). Therefore, we concluded that the candidate preparation would be suitable as a national standard for testing the potency of JE vaccine (inactivated).

A one-step real-time quantitative RT-PCR assay in combination with automated RNA extraction was evaluated for routine testing of HCV RNA in the laboratory. Specific primers and probes were developed to detect 302 bp on 5'-UTR of HCV RNA. The assay was able to quantitate a dynamic linear range of $10^7-10^1$ HCV RNA copies/reaction ($R^2=0.997$). The synthetic HCV RNA standard of $1.84{\pm}0.1\;(mean{\pm}SD)$ copies developed in this study corresponded to 1 international unit (IU) of WHO International Standard for HCV RNA (96/790 I). The detection limit of the assay was 3 RNA copies/reaction (81 IU/ml) in plasma samples. The assay was comparable to the Amplicor HCV Monitor (Monitor) assay with correlation coefficient r=0.985, but was more sensitive than the Monitor assay. The assay could be completed within 3 h from RNA extraction to detection and data analysis for up to 32 samples. It allowed rapid RNA extraction, detection, and quantitation of HCV RNA in plasma samples. The method provided sufficient sensitivity and reproducibility and proved to be fast and labor-saving, so that it was suitable for high throughput HCV RNA test.

Di-n-butyl phthalate (DBP) is not only a plasticizer and solvent used in industry but also one of endocrine disruptor chemicals, a low level contaminant found in a wide variety of different media ranging from drinking water to infant formulae. To evaluate the cytotoxic function of NK cells in mice after contact with DBP, C57BL/6 female mice were orally dosed with di-n-butyl phthalate (250, 500, or 750 mg/kg body weight) for 14 consecutive days, and the control mice were administered vehicle (corn oil).(omitted)

Dimethyl phthalate(DMP). diethyl phthalate(DEP), di-n-butyl phthalate (DBP). butyl benzyl phthalate(BBP). bis(2-ethylhexyl)phthalate(DEHP) and di-n-octyl phthalate(DOP) in lotions was determined by gas chromatography. and benzyl benzoate was used as the intermal standard. The separation of the six phthalates and internal standard was optimized, and the optimal analytical conditions were as follows: column. DB-1701 (I.D. 0.25mm): mobile phase. helium: oven temperature 20$0^{\circ}C$ (10 min) ${\rightarrow}10^{\circ}C$/min ${\rightarrow}260^{\circ}C$/min(30min), injector temperature 23$0^{\circ}C$, detector temperature 28$0^{\circ}C$.
