  • Hepatoprotective activity of different extracts of Citrullus colocynthis L. sch. (roots) (cucurbitaceae) was investigated in albino rats by inducing hepatotoxicity with carbon tetrachloride. The alcoholic extract of Citrullus colocynthis sch. 100 mg/kg b.w. has been shown to posses significant hepatoprotective effect by lowering the serum level of transaminases (GPT & GOT), alkaline phosphate (ALP) and bilirubin (P < 0.05 to P < 0.001).

  • 산업폐기물 소각시스템으로 현재 널리 이용되고 있는 대형 로타리 킬른형 소각로를 모델로 선정하여 소각로 설계에 필요한 제반변수에 대한 영향을 슈퍼컴퓨터를 이용하여 분석하였다. 화염억제 작용이 있으며 소각처리시 유독물질을 배출하는 $CCl_4$를 폐기물로 주입하는 경우 비평형 난류반응모델을 도입하여 반응장 해석을 한 결과 실험결과와 정성적으로 일치된 결과를 얻을 수 있었다.

  • A gas chromatographic utilizing procedure headspace gas analysis is performed to study effect of malotilate on levels of ethanol and its metabolite acetaldehyde in a blood sample from the rat. The concentrations of ethanol and acetaldehyde were determined simultaneously at 1, 3, and 6h after ethanol administration. Our results would suggest the malotilate could promote clearances of ethanol and acetaldehyde in blood, and could accelerate it, especially, in $CCl_4$ pretreated rats.

  • Pharmacological studies have been carried out with the methanol extract of the whole plant of Pseudostellaria palibiniana Ohwi (Caryophyllaceae). The results showed that it had stimulation effect on heart, hypotensive actions depending on extract contents, stimulation effect on respiration, contraction on excised intestines, enhancement of tension on excised uterus, antineoplastic activity on Ehrlich carcinoma, liver protective activity against $CCl_4$ intoxication, writhing and diuretic activities.

  • A theory in which the Enskog hard sphere collisional dynamics complements the hydrodynamic theory is applied to the fast modulation dephasing dynamics in liquids which leads to homogeneous line broadening in the isotropic Raman spectra. The dephasing times of several molecules in pure liquids and in trace solutions in the solvent $CCl_4$ are calculated and these are compared with experimental values. The temperature dependence of the dephasing time of liquid acetonitrile and the isothermal density dependence of the dephasing time of liquid methyl iodide are also investigated.
