  • Many diabetic patients develop serious complications during the course of the disease, including cardiovascalar disorders, nepropathy, neuropathy and retinopathy. Because some physiological changes occurring in diabetes mellitus patients could alter the pharmacokinetics of drugs used to treat the disease, the pharmacokinetics of gentamycin was investigated after intravenous administration (2 mg/kg) to control rabbits and acute or chronic alloxan-induced diabetes mellitus rabbits (AIDRs). After intravenous administration, the serum concentrations of gentamycin were significantly higher between 6 and 12 hr in chronic AIDRs compared with those in control rabbits. The AUC was significant greater in chronic ($31.91\;{\pm}\;3.76\;{\mu}g/ml{\cdot}hr$) AIDRs than that in control ($21.60\;{\pm}\;2.45\;{\mu}g/ml{\cdot}hr$) rabbits. Total body clearance (CLt) in AIDRs were significantly decreased compared with that in control rabbits. Cumulative urinary excretion of gentamycin was decreased, although not significantly, in AIDRs compared with that in control rabbits.

  • This study was accomplished to illuminate factors of contamination of microbes in the culture medium and effect of antibiotics on prevention of contamination in the medium when bovine follicular oocyte was matured, fertilized and developed in vitro. 1. When washed or unwashed semen diluted with TCM 199 was incubated for 24∼72hr, contamination was come out. 2. When diluted semen with TCM 199 which has penicillin, streptomycin, gentamycin, kanamycin or nystatin was incubated for 24∼72hr, contamination was not come out only in kanamycin. 3. When imported semen which was diluted in TCM 199 with penicillin, streptomycin, gentamycin, kanamycin or nystatin was incubated for 24∼72hr, contamination was not come out in all treatments. 4. When semen which was diluted in BO, CZB, Ham's F10 or TCM 199 was incubated for 24∼72hr, kanamycin showed no contamination in all treatments, but gentamycin showed contamination in CZB, Ham's F10 and TCM 199. 5. When the semen diluted in BO was moved at 24hr after incubation into BO and incubated for 72hr, contamination was not come out, but when it was moved into the TCM 199 and incubated for 72hr, contamination was come out at 48 to 72hr of incubation. 6. When the semen diluted in BO, BO+BSA or BO+FBS containing gentamycin, kanamycin or nystatin was incubated for 24∼72hr, the diluted semen in BO or BO+BSA showed no contamination in all antibiotics but the diluted semen in BO+FBS showed no contamination only in kanamycin. 7.The Pseudomonas cepacia, Serratia liquefaciens, Klebsiella pneumaniae was respectively isolated in the semen of A, B, and C bull and the microbes are highly affected by amikacin, tobramycin and kanamycin. 8. When bovine folicular oocyte was in vitro matured, fertilized and developed in the simple medium with kanamycin, 26.6% was developed to over 32cell stage embryo.

  • 인삼 saponin과 항생 물질의 사용에 따른 in vivo에서 출현 가능한 영향을 in vitro에서 미생물을 대상으로 검토하였다. aminoglycoside 항생 물질인 streptomycin·sulfate, kanamycin·sulfate, gentamycin·sulfate 등은 인삼 saponin과의 상호 작용으로 그 항균 활성이 대체로 상승되었으며 Erwinia aroideae에 대해서만 그 항균활성이 항상 상승되지는 않는 경향을 나타내었다. benzene 유도체항생 물질인 chloramphenicol은 인삼 saponin과의 상호 작용으로 그 항균활성이 Salmonella typhi. Aerobacter aerogenes, Serratia속 세균등에서는 상승하였으나 Bacillus suhtilis, Bacillu, megaterium, Escherichia coli균에서는 활성이 감소되었고 그 밖의 세균에서는 항균활성에 변화를 나타내지 못하였다.

  • To investigate e effect of antimicrobial ointments on wound healing wound contraction was measured in rabbits with daily application of ointments. Full thickness skin defects(1cm$\times$1cm) were made in three different areas on the back. Percentage of wound contraction based on wound area measured on the day of surgery was calculate every other day until day 9. The percentages of wound contraction in saline and gentamycin solution-treated groups were 86.0% and 75.0%, respectively and higher than those in animicrobial ointments, especially gentamycin cream, silver sulfadiazine and madecasol ointments. It was suggested that the effect of antimicrobial ointments on wound healing were not superior to at of physiological saline in respect to wound contraction in rabbits.

  • Caveolin may be a molecular target for modulation of aging process in cochlear hair cells and have association with oxotoxicity. First we investigated the basal expression of caveolin-1, caveolin-2, caveolin-3, nitric oxide synthase, and superoxide dismutase in UB/OC-1 cochlear hair cell line. By using a RNA interference technique, we investigated whether down-regulation of caveolin influenced telomerase activity and reactive oxygen species (ROS) production in cochlear hair cells. In addition, cisplatin and gentamycin, known ototoxic drugs, were administered to the cochlear cells to determine their impact on caveolin expression. Further attempts at elucidating cellular aging mechanism with caveolin and ototoxic drugs were carried out. The main discoveries were the presence of caveolin-1 in UB/OC-1 cells and that down-regulation of caveolin-1 reduced protein kinase A activity. Telomerase was activated by caveolin down-regulation and caveolin down-regulation inhibited oxidative stress at the mitochondrial level. When cisplatin and gentamycin were administered to the cochlear hair cells during a caveolin expression state, a decrease in telomerase activity and increase ROS activity was observed. Caveolin-1 may modulate the senescent mechanisms in cochlear cells. An increase in caveolin-1 levels can lead to ROS production in the mitochondria which may cause ototoxicity.

  • Bifidobacteria를 다양한 유산균이 함께 공존하는 발효식품에 첨가시 이들을 분리할 수 있는 선택배지를 제조하기 위해 다양한 항생제의 생육저해 효과를 조사하였다. Gentamycin과 ripampicin은 $100\;{\mu}g/mL$의 농도에서 일반 유산균의 생육을 심하게 억제하였으나, bifidobacteria의 생육은 억제하지 않았다. ampicillin은 $50\;{\mu}g/mL$의 농도에서 일반 유산균은 거의 생육하지 못하였으나, bifidobacteria의 생육도 억제되었다. fosfomycin은 $100\;{\mu}g/mL$이상의 농도에서 일반 유산균보다 bifidobacteria의 생육이 더 억제되었다. Neomycin $80\;{\mu}g/mL$, gentamycin $50\;{\mu}g/mL$, ripampicin $50\;{\mu}g/mL$, nalidixic acid $15\;{\mu}g/mL$, $LiCl_2$ $3\;{\mu}g/mL$의 항생제가 함유된 MRS배지를 이용하였을 때 김치나 치즈에 존재하는 다양한 유산균의 생육을 억제시키지만 bifidobacteria의 생육을 억제시키지 않아 이를 선택적으로 분리할 수 있었다.

  • A total of 98 strains of Bordetella bronckiseptica isolated from pigs affected the infectious atrophic rhinitis(AR) during 1978 were surveyed for drug sensitivity to 26 chemotherapeutic agents, and minimum inhibitory concentration(MIC), incidence rate of resistant strain and resistant patern from the strains which were obtained from the different pig farm in Jeonnam province were examined. The results obtained are summarized as follows. 1. Most of the strains tested were resistant to Ampicillin (AB, PC), spiramycin(SPO, sulfa drugs (SD) (MIC:$400.0{{\mu}g/ml}$) and streptomycin(SM) (MIC:$200.0{{\mu}g/ml}$). Of the 75.0% of strains were also resistant to penicillin(PC) (MIC:$200.0{{\mu}g/ml}$) and of the 14.3 of strains were inhibited to grow to tetracycline(TC), chlortetracycline(CTC), oxytetracyc-line(OTC), erythromycin(EM), tylosin(TS), leucomycin (LM) and chloramphenicol (CP) (MIC:$6.25{{\mu}g/ml}$). On the other hand, most of the strains tested were inhibited to grow to kanamycin(KM), gentamycin(GM) neomycin(NM) (MIC:$25.0{{\mu}g/ml}$) and to colistin(CL) (MIC:$12.5{{\mu}g/ml}$). 2. Incidence rate of resistant strains to main chemotherapeutic agents was 100.0% of sulfa drugs, 96.4% of streptomycin, 85.7% of penicillin, tetracycline, chloramphenicol and erythromycin, 46.4% of gentamycin, 17.9% of colistin and 0.0% of kanamycin and nalidixic acid.
