박정흠,김준한,이상렬,박종우,박창엽,Park, Jeong-Heum,Kim, Joon-Han,Lee, Sang-Yeol,Park, Chong-Woo,Park, Chang-Yub 한국전기전자재료학회 1998 전기전자재료학회논문지 Vol.11 No.2
$(Pb_{0.72}La_{0.28})Ti_{0.93}O_3(PLT(28))$ thin films were fabricated by pulsed laser deposition. PLT films deposited on $Pt/Ti/SiO_2/Si$ at $600^{\circ}C$ had a preferred orientation in (111) plane and at $550^{\circ}C$ had a (100) preferred orientation. We found that (111) preferred oriented films had well grown normal to substrate surface. This PLT(28) thin films of $1{\mu}m$ thickness had dielectric properties of ${\varepsilon}_r$=1300, dielectric $loss{\fallingdotseq}0.03 $. and had charge storage density of 10 [${\mu}C/cm^2$] and leakage current density of less than $10^{-6}[A/cm^2]$ at 100[kV/cm]. These results indicated that the PLT(28) thin films fabricated by pulsed laser deposition are suitable for DRAM capacitor application.

세 마리의 군 사역견이 신체검사와 직장 검사 등을 통해 항문주위 누공으로 진단되었다. 초기 치료는 단기간의 싸이클로스포린과 케토코나졸과 0.1%의 타크로리무스 연고제제로 시작하였다. 병변이 거의 다 치료가 되었을 시점부터 0.1% 타크로리무스 연고제제를 도포 횟수를 줄여서 실시하였다. 세 마리 모두에서 병변은 2-8주 사이에 별다른 부작용을 동반하지 않고 거의 대부분 사라졌으며, 완치는 증례 1, 2, 3에서 각 13, 6, 4주에 이루어졌다. 이 세가지 약물의 병용 프로토콜은 항문낭과도 연결된 항문주위 누공에서도 병변을 해소하는데 효과적이었으며, 특히 초기에 빠른 병변의 해소에 도움이 되어 병변으로부터 발생되는 고통을 경감시켜주는 기간이 늘어나는 것이 강점이라고 할 수 있다. 또한 시간적인 측면 외에도 경제적인 측면에서도 도움이 되므로 개에서 발생하는 항문주위 누공에 효과적인 치료 프로토콜로 유용하게 사용될 수 있을 것으로 사료된다. Three military working dogs (MWDs) were diagnosed with perianal fistulae after a complete physical examination and rectal palpation. The initial treatment protocol was used with short-term oral ciclosporine (CyA) and ketoconazole and 0.1% topical tacrolimus ointment. When lesions were nearly healed, treatment was continued with 0.1% tacrolimus ointment only at a lower frequency. The lesions improved significantly within 2-8 weeks with no noticeable side effects. Complete recovery was determined at weeks 13, 6, and 4 for cases 1, 2, and 3, respectively. This combination protocol was effective at resolving or reducing perianal fistulae (PAF) lesions even communicating with anal sacs in three dogs. The major benefit of this protocol was the rapid reduction of fistulae lesions and this could be helpful to extend the pain-free period. Moreover, this protocol appeared cost-saving as well as time-saving option for PAF dogs.

This study was attempted to investigate the influence of estrogen on the contractile function of rat urinary bladder. Animals were pretreated for 1,5 or 10 weeks with estrogen and the contractile response of the detrusor muscle was induced by the treatment with acetylcholine, phenylephrine, ATP or KC1. 3^H-nitrendipine binding was also carried out with the homogena of the rat urinary bladder. The results were as follows: 1. Acetylcholine (10^-6 or 5 × 10 exp (-6)M)-induced contraction was significantly increased in estrog treated group for 1 or 5 weeks (p<0.05), and atropine (10^-6M) completely inhibted the acti of acetylcholine in control and estrogen treated group. 2. Phenylephrine (10^-3M)-induced contraction was significantly increased in estrogen treated group for 1 or 5 weeks (p<0.05), and prazosin(2.2 × 10 exp (-6)M) inhibited the action of phenylephrin about 70-75% in both groups. 3. .ATP(10^-3M)-induced phasic contraction was significantly increased in estrogen treated group for 1, 5 or 10 weeks (p<0.05), and diltiazem(l0 ^-6M) inhibited the action of ATP about 45~74% in both groups. 4. KC1(27mM)-induced contraction was slightly increased in estrogen treated group, and diltiazem(10^-6M) inhibited the action of KCl about 72~75% in both groups. From the above results, it was suggested that the increased response to acetylycholine, phenyl ephrine, ATP or KC1, with the treatment of estrogen, may be related to the alteration of cell membrane and/or the numbers of calcium channels.
급성 세균성 감염증에 대한 Cefotetan(Yamatetan^ⓡ)의 임상적 효과
김주옥,안원전,박종훈,노흥규,박종우 충남대학교 의과대학 지역사회의학연구소 1987 충남의대잡지 Vol.14 No.1
Total 20 cases of infectious diseases were treated with Cefotetan at the Dept. of internal medicine, Chung Nam National University Hospital, Dae Jeon, Korea, from January 1985 to April 1985. Among 20 cases, 6 were the patients with acute pyelonephritis, 7 were pneumonia, 2 were acute cholecystitis, 2 were chronic bronchitis, 2 were cellulitis and 1 was lung abscess. The response was good in 16 cases, and poor in 4 cases. The laboratory tests were normal except I which was reversible. (mild elevation of SGOT and SGPT) The side effects were noted in 2 cases, such as skin eruption and drug fever, which were improved with supportive care. Cefotetan was thought to be useful against acute bacterial infections of respiratory, urinary, biliary tracts and cutaneous tissue.
