Three different cats who had chronic kidney disease (CKD) were treated for more than one month with fluid therapy in an animal clinic. Although this long-term treatment and hospitalization, there was no clinical improvement in clinical signs as well as serum biochemical indexes including blood urea nitrogen (BUN), creatinine (CREA), and phosphate (PHOS). All cases were then injected three times with allogeneic stem cells through an intravenous route for treatment on Day 0, 7, and 14 or 30. On the same day, clinical observation and blood tests for serum biochemistry were conducted together. Upon administrating stem cells to the CKD cats, clinical conditions and the indexes of BUN and CREA were clinically improved within normal ranges. Additionally, one of the cats who had the renal cysts presented clinical improvement with showing decreased cysts size than before.

A cat who is a 15-year-old and spayed female visited an animal clinic with severe coughing symptoms. Since the cat's coughing symptoms had worsened from the age of 10 and X-rays showed a bronchial pattern in the lungs, it was diagnosed as Chronic Obstructive Pulmonary Disease (COPD). She received three injections of stem cells isolated from the amniotic membrane on days 0, 7, and 23. Although there was no improvement in the clinical findings on the x-ray, the number of coughing was significantly reduced. In addition, even after long-term follow-up post treatment for a month, she was stable with almost no coughing.

When {Xni|1 ≤ i ≤ n, n ≥ 1} be an array of rowwise negatively superadditive dependent(NSD) for semi-Gaussian random variables and {ani|1 ≤ i ≤ n, n ≥ 1} is an array of constants, we study the almost sure convergence of weighted sums ∑ni=1 aniXni under some appropriate conditions and we obtain some corollaries.

Hershberger assay is known as one of the in vivo-short-term scrrning assays for endocrine disrupting chemicals (EDCs), but this method is not a validated test system. In the present study, the establishment of Hershberger assay to detect EDCs was tried using a model substance, di(n-butyl)phthalate (DBP), a plasticizer for plastics. Thirty-six immature male rats were randomly assigned to six groups: DBP 0, 40, 200, and 1000mg/kg, a positive control (flutamide 20 mg/kg), and a combination group(DBP 1000mg/kg and testosterone 50 ug/kg). DBP and flutamide were administered by gavage to male rats from day 21 to 40 post partum. Testosterone was subcutaneously injected during the same period. We evaluated body weigth gain, weights of ventral prostate, seminal vesicle, and levator ani and bulvocavernous muscle, and serum concentrations of testosterone and lutenizing hormone in male rats. The weights of seminal vesicle and levator ani and bulvocavernous muscle of males receiving 1000mg/kg of DBP was significantly lower than controls. There was no effect of DBP-treatment on body weight gain, prostate weight, and hormone concentrations. In the positive control group, the weights of seminal vesicle and levator ani and bulvocavernous muscle of males receiving 20mg/kg of flutamide were significantly lower than controls. In the combination group, there was no effect of co-treatment of DBP and testosterone on all parameters effect against DBP. This method was found to be a useful short-term screening assay system for EDCs.

We tested Trichoderma harzianum as a biocontrol agent for Rhizoctonia solani AG2-1, using six natural antifungal materials to improve its efficacy. Among the six materials tested, peony (Paeonia suffruticosa) root bark (PRB) showed the strongest antifungal activity against R. solani AG2-1, and was not antagonistic to T. harzianum. Scanning electron microscopy showed that treatment with PRB extract resulted in shortened and deformed R. so/ani AG2-1 hyphal cells. The control of radish damping-off caused by R. so/ani AG2-1 was greatly increased by combined treatments of T. harzianum and PRB, as compared with either of the two treatments alone, with the control effect increased from 42.3-51.5% to 71.4-87.6%. The antifungal compound in PRB, which was isolated in chloroform and identified as paeonol by mass spectrometry, $^1H$ NMR, and $^{13}C$ NMR analyses, inhibited the growth of R. so/ani AG2-1 but not that of T. harzianum. Thus, PRB powder or extract may be used as a safe additive to T. harzianum to improve the control of the soil borne diseases caused by R. so/ani AG2-1.

4주령의 0.6 kg 암컷 스콧티쉬 폴드 고양이가 예방 접종을 위해 내원하였다. 신체 검사에서 수양성 분변이 질에서 나오는 것이 확인 되었고 항문은 폐쇄되어 있었다. 방사선 양성 조영 검사에서 직장질루, 확장된 결장이 확인 되었다. 영상 검사에 기초하여 Type III 의 항문 무형성과 직장 질루가 병발한 것으로 최종 진단 하였다. 수술적인 직장 질루의 폐쇄와 항문의 재건이 실시되었다. 수술 후 소화능력을 향상시키기 위해서 락툴로즈와 식이요법을 실시 하였고, 고양이는 수술 후 2주에 배변 조절이 가능해졌으며, 8개월 후 추적조사에서 합병증 없이 배변조절 상태가 유지 되었다.

The strain KIST612, initially identified as E. limosum, was a suspected member of E. callanderi due to differences in phenotype, genotype, and average nucleotide identity (ANI). Here, we found that E. limosum ATCC 8486^T and KIST612 are genetically different in their central metabolic pathways, such as that of carbon metabolism. Although 16S rDNA sequencing of KIST612 revealed high identity with E. limosum ATCC 8486^T (99.2%) and E. callanderi DSM 3662^T (99.8%), phylogenetic analysis of housekeeping genes and genome metrics clearly indicated that KIST612 belongs to E. callanderi. The phylogenies showed that KIST612 is closer to E. callanderi DSM 3662^T than to E. limosum ATCC 8486^T. The ANI between KIST612 and E. callanderi DSM 3662^T was 99.8%, which was above the species cut-off of 96%, Meanwhile, the ANI value with E. limosum ATCC 8486^T was not significant, showing only 94.6%. The digital DNA-DNA hybridization (dDDH) results also supported the ANI values. The dDDH between KIST612 and E. callanderi DSM 3662^T was 98.4%, whereas between KIST612 and E. limosum ATCC 8486^T , it was 57.8%, which is lower than the species cut-off of 70%. Based on these findings, we propose the reclassification of E. limosum KIST612 as E. callanderi KIST612.

목적: 본 연구는 임상에서 종종 마주치는 만성적이고 낫지 않는 항문거근증후군 환자의 한의학적 치료 유용성을 공유하고자 한다. 방법: 14년 전에 치질수술 후에 발생한 항문통증이 개선되지 않고 지속되어 고통스러웠던 47세 남자 환자의 병력과 한의학적 치료 후의 임상적 개선과정을 자세히 제시하였다. 결과: 환자는 평소 건강하였는데, 치질수술 후에 대변을 보면 시작되는 항문통이 발생하였으며, 경우에 따라서는 오전 내내 불편함이 지속되었다. 14년 동안 종종 줄어들기도 하였지만 점진적으로 심해지는 경과를 보였고, 특히 1년 전부터는 더욱 심해졌으나 다양한 치료에도 호전이 없었다. 외국에 거주하는 이유로 한국에 방문하는 기회에 본원에서 한의학적 변증 하에 한약치료 및 약침을 포함하는 침치료와 뜸 치료 후 빠르게 호전되었다. 8주 정도의 치료 후에 NRS 2로 개선되어 만족한 상태로 출국하였다. 결론: 본 증례는 특별한 치료법이 부재하는 만성적이거나 혹은 난치성 항문거근증후군에 대하여 한의학적 치료법이 하나의 훌륭한 치료법일 수 있음을 보여주는 임상 예로서 의미가 있다고 하겠다.

본 논문에서는 비접촉식 미세 측정 광학기에 의해 측정된 이미지를 Stitching 기술과 B-Spline 보간법에 의해 보다 빠르고, 정밀한 복원 기법을 제안한다. 이를 위해 먼저 각각의 이미지로부터 매칭, 피매칭 템플릿(Template)을 검출한다. 그런 다음 두 이미지의 오버랩(Overlap)되는 부분을 기준하여 기준면으로부터 roll, pitch, yaw 오차를 계산하여 매칭시킨다. 마지막으로, B-Spline 보간법에 의해 매칭된 부분을 연속화한다. 제안된 방법은 실험을 통해 그 응용 가능성을 증명한다.
