The present study was carried out to establish a practical regimen for artificial parturition induction using prostaglandin F2$\alpha$(PGF2$\alpha$) and estradiol-benezoate in Korean native goats. The effect of parturition induction and the time intervals to induced parturition after injection were investigated. The birth weight and body weight of kids at 15 days of age were measured. A total of 24 pluriparous goats were offered for this experiment. The animals were divided into 4 goats per treatment by the injection time(142, 145 or 148 day of pregnancy) and dosage(5.0$\times$10 or 7.5$\times$7.5mg). The results obtained were summarized as follows : A total of 24 pregnant goats were intramusculary treated with 5.0$\times$10 or 7.5$\times$7.5mg of PGF2$\alpha$ and estradiol-benzoate for parturition induction of Day 142, 145 or 148 of gestation. Parturition was induced in all of the goats(100%) treated. The kids produced from induced parturition were all healthy. The time intervals to induced parturition after PGF2$\alpha$ and estradiol-benezoate injection of 5.0$\times$10 or 7.5$\times$7.5mg to pregnant goats on Day 148(23.22$\pm$0.51~23.40$\pm$1.26hrs) were significantly(P<.01) shorter than those of the 142 days of the gestation(26.34$\pm$2.22~28.39$\pm$3.02hrs). No significant difference was found in the time intervals between the doses(5.0$\times$10 or 7.5$\times$7.5mg) treated for parturition induction. The birth weight of kids from induced parturition was no significant difference between on Day 148 and on Day 142 of gestation. However, the birth weight of kids from parturition induced on Day 148 was found significantly(P<.01) heavier than that of the 142 days of gestation. The body weight of kids at 15 days old was also significantly(P<.01) lighter in the parturition induced on day 142 than those on Day 142. The birth weight and body weight of kids at 15 days old were not affected by 5.0$\times$10 or 7.5$\times$7.5mg injection of PGF2$\alpha$ and estradiol-benzoate for inducing parturition. From the above results, it was concluded that the parturition induction by PGF2$\alpha$ and estradiol-benezoate injection of 5.0$\times$10 or 7.5$\times$7.5mg on Day 142 of gestation, which was correspondent to 8 days before expected spontaneous parturition, was available without any significant troubles.

Indobufen ($Ibustrin^{(R)}$), a reversible inhibitor of platelet aggregation, exists in two enantiomeric forms in 1:1 ratio. Here, we characterized the anti-platelet effect of S- and R-indobufen using response surface modeling using $NONMEM^{(R)}$ and predicted the therapeutic doses exerting the maximal efficacy of each enantioselective S- and R-indobufen formulation. S- and R-indobufen were added individually or together to 24 plasma samples from drug-naïve healthy subjects, generating 892 samples containing randomly selected concentrations of the drugs of 0-128 mg/L. Collagen-induced platelet aggregation in platelet-rich plasma was determined using a Chrono-log Lumi-Aggregometer. Inhibitory sigmoid $I_{max}$ model adequately described the anti-platelet effect. The S-form was more potent, whereas the R-form showed less inter-individual variation. No significant interaction was observed between the two enantiomers. The anti-platelet effect of multiple treatments with 200 mg indobufen twice daily doses was predicted in the simulation study, and the effect of S- or R-indobufen alone at various doses was predicted to define optimal dosing regimen for each enantiomer. Simulation study predicted that 200 mg twice daily administration of S-indobufen alone will produce more treatment effect than S-and R-mixture formulation. S-indobufen produced treatment effect at lower concentration than R-indobufen. However, inter-individual variation of the pharmacodynamic response was smaller in R-indobufen. The present study suggests the optimal doses of R-and S-enantioselective indobufen formulations in terms of treatment efficacy for patients with thromboembolic problems. The proposed methodology in this study can be applied to the develop novel enantio-selective drugs more efficiently.

Objectives: Surgical intervention for removal of an impacted third molar can lead to significant pain and swelling. Corticosteroids show promise for mitigating postoperative sequelae across various surgical contexts. The use of corticosteroids following minor oral surgery, though controversial, has already been proven effective. However, little research has explored peroral prescription of corticosteroids despite its convenience for outpatients and for non-surgeons like implantologists and periodontists and others who don't have access to needle injections. The aim of this study was to address a void in the literature by comparing the effects of two styles of preoral administration of prednisolone after surgical removal of the mandibular third molar and to determine which style minimizes postoperative sequelae. Materials and Methods: A randomized, split-mouth clinical study was conducted to investigate the efficacy of two different styles of preoral prednisolone in mitigating postoperative sequelae following surgical extraction of impacted mandibular third molars. Fifteen participants were enrolled in the study. Random selection was used to determine the prescription style for the right and left mandibular arch. Group A included those who received a single dose of prednisolone 25 mg, while group B received prednisolone 5 mg postoperatively for a period of three days (5 mg three times/day on the first postoperative day, 5 mg twice/day on the second postoperative day; 5 mg once/day on the third postoperative day). Results: There was a significant difference in the distance between the corner of the mouth and tragus, which decreased with the time interval with respect to group B when compared to group A. Conclusion: The present study showed that a three-day tapered dose of prednisolone postoperatively was more effective in reducing post-extraction sequelae than a single-dose regimen.

목 적 : 본 연구는 발열성 요로감염으로 입원한 영아에서 항생제 연관 설사(Antibiotic-associated Diarrhea, 이하 AAD)의 양상 및 연관인자를 조사하였다. 이 연구는 영아 AAD의 예방과 치료에 사용되는 생균제에 대한 기초 연구이다. 방 법 : 가천의대길병원에서 2008년 1월부터 2010년 9월 사이에 급성 발열성 요로감염으로 입원한 생후 3-6개월의 영아들의 의무기록을 후향적으로 조사하여 AAD를 보인 환자(AAD군)와 보이지 않은 환자(non-AAD군)를 비교하였다. AAD군 내에서 사용한 항생제 요법과 용량, 설사의 양상을 비교하였다. 결 과 : 총 147명 중 AAD군은 54명(36.7%)이었고, 이 중 3세대 세팔로스포린($3^{rd}$ CS) 단일요법군, $3^{rd}$ CS과 비세팔로스포린 혼합요법군, 비세팔로스포린 혼합요법군 간의 설사의 발현 시점, 지속기간 및 횟수의 유의한 차이가 없었다(P>0.05). AAD군과 non-AAD군과의 cefotaxime 사용량의 유의한 차이는 없었다. 결 론 : 생후 3-6개월 영아의 발열성 요로감염 환자에서 AAD는 항생제의 요법과 평상적 투여량 범위내에서 용량에 관계없이 흔하게 발생하였다. 영아 AAD의 예방과 치료에 사용되는 생균제의 효과에 대한 추가적인 연구가 필요하다.

항결핵치료 시작 후 3개월간의 치료 경과와 치료 순응과의 관련성을 조사하기 위하여 3개 보건소(대구시 달성군, 경주시, 구미시)에 1995년 10월 15일 현재 단기 6개월 표준처방으로 치료 시작 후 3개월 이상 경과된 초치료 결핵환자 중 계속적인 추적관찰에서 누락된 10명을 제외하고 104명의 자료를 분석한 결과는 다음과 같다. 연구 대상자 104명 중 호전군은 80.8%였고, 비호전군은 19.2%였다. 호전군과 비호전군간에 성, 연령, 교육 수준, 직업, 동반 가족유무, 흡연 및 음주습관의 변화 등에 유의한 차이는 없었고, 평균 연령은 비호전군이 51세로 호전군 42세보다 많았으나 유의 한 차이는 아니었다. 호전군에서는 약제의 복용을 식전과 식후 30분에 복용하는 경우(p<0.05), 약의 복용을 잊지 않도록 가족들이 챙겨 주는 경우(p<0.05), 약을 규칙적으로 복용하는 경우(p<0.01), 항결핵치료 도중 의문점을 가족이나 결핵담당자와 상의하는 경우(p<0.01) 등이 유의하게 많았다. 비호전군에서는 당뇨병이나 위장 질환 등을 않고 있는 경우가 유의하게 많았다(p<0.01). 결핵에 대한 지식점수는 호전군이 12.9로 비호전군 10.6보다 유의하게 높았고(p<0.01), 지식정도의 문항에 대한 신뢰도 검증 결과 신뢰성$(Cronbach'\alpha:0.703)$이 있었다. 치료경과를 호전군과 비호전군으로 나누어 종속변수로 놓고 시행한 다중 지수형 회귀분석에서는 약의 복용을 잊지 않도록 가족들이 챙겨주는 경우(p<0.05)가 유의한 변수로 채택되었고, 결핵에 대한 지식이 높은 경우(p=0.054), 약을 규칙적으로 복용하는 경우(p=0.062), 항결핵치료 도중 의문점을 가족이나 결핵담당자와 상의하는 경우(p=0.075)는 경계역의 변수로 채택되었다. 결론적으로 약을 규칙적으로 복용할 수 있도록 항결핵치료에 대한 신념을 불어넣고 경각심을 높임으로써 환자의 치료 결과를 향상시킬 수 있을 것으로 생각되며, 향후 단기 6개월 표준요법에 의한 치료에 있어서 치료시작 후 3개월간의 치료 경과로 치료 결과를 예측하고 환자의 치료순응을 평가하기 위한 변수로 사용하기 위해서는 보다 많은 결핵환자를 대상으로 한 연구가 필요할 것으로 생각된다. 또한 환자의 치료 순응을 높이기 위하여 환자에 대한 교육과 의사 또는 결핵관리자와 환자, 조력자간의 강한 유대 관계의 형성에 도움을 줄 수 있는 방안의 모색이 필요할 것으로 생각된다.
