After long exposure to low-density $SO_2$ the five tree species showed different changes in their visible damage: Ailanthus altissima showed no visible damage; Acanthopanax sessiliflorus, Populus alba ${\times}$ Populus glandulosa, and Platanus orientalis showed typical damage of yellow spots on their leaves; and Liriodendron tulipifera showed serious damage on the end of leaf tip. The photosynthesis rate of Liriodendron tulipifera and Acanthopanax sessiliflorus was usually lower than the control group: Ailanthus altissima, Populus alba ${\times}$ Populus glandulosa, and Platanus orientalis showed no difference from the control group, while Acanthopanax sessiliflorus and Liriodendron tulipifera showed large changes. In regard to the light compensation points, Ailanthus altissima showed similar values, Populus alba ${\times}$ Populus glandulosa and Platanus orientalis exposed to $SO_2$, showed 3 to $5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ higher values than the control group, and Acanthopanax sessiliflorus and Liriodendron tulipifera exposed to $SO_2$ showed approximately twice higher light compensation points.

This study was designed to investigate the effects of Acanthopanax sessiliflorus 5.,M (ASS) on the regional cerebral blood flow (rCBF) and mean arterial blood pressure (BP) in normal rats and ischemic rats. Experimental groups of rCBF and BP in normal and ischemic rats as follows ; ALE was injected ASS leaves 45% ethyl alcohol extract, ASE was injected ASS stems 45% ethyl alcohol extract, ARE was injected ASS roots 45% ethyl alcohol extract. The results were as follows ; In normal rats, ALE and ARE significantly increased rCBF in a dose-dependent manner, but ASE significantly decreased rCBF and MABP in a dose-dependent manner, ALE increased MABP In ischemic rats, rCBF was significantly and staDly improved by ARE (10 mg/kg, i.p.) during the period of cerebral reperfusion, which was contrasted with the findings of rapid and marked increase in control group. From the above results, it was thought that all part of Acanthopanax sessiliflorus $S_{EEM}$ was effective for hemodynamics and especially ARE was more effective than other parts.

Efficacy of antioxidative activity and nitrite scavenging ability of methanol extract from Acanthopanax sessiliflorus was investigated. Electron-donating ability of extract at $RC_{50}$ was 29.93 ${\mu}g/mL$. After addition of 0.96 mg/mL extract, autooxidation of pyrogallol decreased to 22.85% by superoxide dismutase-like activity. In antioxidative activity of extract against linoleic acid during incubation times of 24, 48, 96 hours at $40^{\circ}C$, lipid peroxidation values significantly decreased by 48.89%, 45.0%, 46.34% with addition of 0.2 mg/mL, respectively. Total phenolic content was determined as gallic acid equivalents (GAE) and values revealed $410.25{\pm}4.74$ GAE ${\mu}g/mg$ of extract. Nitrite scavenging ability showed the most remarkable effect at pH 1.2, exhibited to 88.3% by addition of 0.2 mg/mL. These results suggest that methanol extract from A. sessiliflorus can be used as bioactive and functional material.

${\gamma}$-Aminobutyric acid (GABA) content in fermented plant products and their main plant materials (aerial part of Acanthopanax sessiliflorus, fruit of Crataegus pinnatifida, and whole plant of Morus alba) was determined by high-performance liquid chromatography. GABA was quantified using a reverse-phase column with a gradient elution program (water:acetonitrile =90:10 to 0:100 for 40 min). UV detection was conducted at 280 nm. GABA content was measured in fermented plant products (15.07 mg/g), aerial part of A. sessiliflorus (4.49 mg/g), fruit of C. pinnatifida (10.59 mg/g), and whole plant of M. alba (2.31 mg/g). The presence of GABA in fermented plant products, including A. sessiliflorus, C. pinnatifida, and M. alba is important in industrial application for health supplements.

Dieldrin, one of the organochlorine pesticides (OCPs), induced the damages in neuroblastoma cells and DNA damages in lymphocytes. The ethanol extracts of A. sessiliflorus leaves were examined for the suppressive effects on the dieldrin-induced cell damages. Moreover, the extract was used to test whether it might inhibit the oxidative DNA damage of lymphocytes using Comet assay. The cell and DNA damage by dieldrin were suppressed in vitro upon treating A. sessiliflorus extract. This result suggests that A. sessiliflorus extract might be useful to reduce dieldrin toxicity.

To establish the optimum condition for plant regeneration from somatic embryos of Acanthopanax sessiliflorus Rupr. et Maxim, a medicinal plant, somatic embryos were induced from zygotic embryo-derived embryogenic callus in hormoen-free MS medium. To induce plantlet conversion, cotyledonary somatic embryos were cultured on MS solid medium with GA$_3$at various concentrations (0~10 mg/L) for three weeks. Plantlets were transferred to 1/3 MS solid medium with 0.5% charcoal for 7 weeks. Stem length was increased proportionally to the concentration and treatment period of GA$_3$. Also, the highest leaf width (8.9 mm) and leaf number (2.84) of plantlet were obtained when plantlets were converted on 5,10 mg/L GA$_3$pretreatments, respectively. The highest plant conversion frequency (66.7%) was obtained when the somatic embryos were cultured on medium containing 5 mg/L GA$_3$ for 3 weeks and then were transferred to 1/3 MS medium with 0.5% charcoal. The highest survival rate of soil transfer was 90% when plantlets were regenerated on medium with 5 mg/L GA$_3$ for 3 weeks and then transferred to plastic pots containing vermiculite and sand mixture for 4 weeks.
