The value of contact angle on powder polymethylmethacrylate(PMMA) and polyvinylidene fluoride(PVdF) has measured by wicking method on the base of Washburn equation for water, glycerol, formamide, diiodomethane, 1,1,2,2,-tetrabromoethane, 1-bromonaphthalene, and hexadecane. The measured values were comparable that of film type contact angle measurement. In wicking method, pore average radius has determined from measured values wetting height and mass of powder to liquid in packed column. From the measured contact angle values, surface free energy(γs) of powder PMMA and PVdF was determined by using geometric mean, van Oss approach method and equation of state of Neumann. It is shown that the results of γs depends on interaction with liquids. The solid-liquid interfacial free energy(γS L), interaction parameter(φ) and work of adhesion(WA)were also determined for powder PMMA and PVdF to water and organic liquids.

A recombinant human erythropoietin (rHuEPO) was administered intravenously at dosage levels of 0, 100, 500, and 2500 IU/㎏/day for a period of 13 weeks. There were no observed clinical signs and deaths related to treatment in all groups tested. Decreases in body weight gain and food consumption were observed only in males of 2,500 IU/㎏ group after 2 weeks. In hematological parameters, erythrocyte content, hematocrit values and hemoglobin concentration were dose-dependently increased in rHuEPO treated groups. The ratio between kidney weight and whole body weight was significantly increased in females of 500 and 2,500 IU/㎏ groups. The spleen weight was also increased in both sexes of 500 and 2,500 IU/㎏ groups. However, the absolute weight change of other organs was not observed. In histopathological examinations, the renal tubular basophilia was observed only in males and females of 2,500 IU/㎏ groups. From these results, it is concluded that the no-observed adverse effect level(NOAEL) of rHuEPO is 100 IU/㎏ in rats in the present study.

The rain water samples were collected at Chunchon and Seoul by using wet only automatic sampler from January 1996 through December 1997. The daily base rain water samples collected over than 95% rainy events during the whole period. The samples were measured both pH and conductivity, and were analysed major ionic components, SO₄^(2-), NO₃^(-), Cl^(-), NH₄^(+), Ca^(2+), Na^(+) and K ^(+), by ion chromatography. In 1996, about 77% sampled rain water showed below pH 5.6 and the 60% of rain water was lower than pH 5.0. The volume weighted average pH was 4.7 at all sites. In 1997, the volume weighted average pH was 4.6 and 4.9 at Seoul and Chunchon, respectively. Among the rain water samples, 87% and 55% of samples showed below than pH 5.6 and 5.0, respectively. The pH value of Chunchon was significantly (p<0.05) lower than Seoul at the rain samples for less than 20 ㎜ rainfall. However conductivity of the rain samples were 20.9 μS/㎝ for 1996 and 27.7 μS/㎝ for 1997 at Seoul, and 19.1 μS/㎝ for 1996 and 14.1 μS/㎝ for 1997 at Chunchon. H₂SO₄AND HNO₃CONTRIBUTED 65.9% and 29.6% of free acidity at Seoul, respectively. The ratio of [NO₃^(-)]/[nss-SO₄^(2-)] were 0.43 at Seoul and 0.51 at Chunchon for rain samples for less than 20 ㎜ rainfall.

김수진,박은지,안승원,김웅,김미운,임현술 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.5

Background: Propofol is a good induction agent. but it has a disadvantage of pain on intravenous injection. Pretreatment of metoclopramide or lidocaine have been reported to reduce pain on injection. thus, we have evaluated the quantity and quality of anagesic effect of metoclopramide and lidocaine. We observed differences in quality of pain according to venous cannula sizes and intravenous injection sites as well as nausea and vomiting in the postoperative state. Methods: Eighty patients scheduled for an elective operation by general anesthesia were chosen according to ASA (Ⅰ or Ⅱ) and divided into four groups randomly. Each group was injected through venous cannulas with normal saline (control group), metoclopramide 5 mg (group 1), netoclopramide 10 mg (group 2), or 2% lidocaine 40 mg (group 3) respectively. Then, propofol was injected of a 2 mg/kg dose with 0.5 ml/sex to all groups and we asked questions about injection pain after 10 seconds. Results: Pain relief was shown in all groups compared with the control. but metoclopramide 10 mg and lidocaine 40 mg pretreatment groups showed significant pain reief. Pain was relieved significantly when the drug was injected in the antecubital area. Postoperative nausea and vomiting were not observed. Conclusions: Metoclopramide 10 mg or lidocaine 40 mg pretreatment to induction by propofol revealed a good analgesic effect for propofol injection pain. (Korean J Anesthesiol 2002; 43: 558~565)
