7개월된 암컷 Cocker spaniel견이 3주전부터 체중감소, 구토, 탈수, 식욕저하를 보이면서 지속적인 미열을 동반한 다음과 다뇨를 주증상으로 시내 병원에 내원하였다. 담당 수의사의 진료내역을 검토한 결과 복수와 간종대, 혈액 도말 검사에서 비재생성빈혈과 흉부방사선 사진에서 좌측 중심부에 불규칙한 음영이 관찰된 것으로 기록되었다. 이후 prednisolone으로 치료하였지만 증상의 경과가 호전되지 않아 정밀진단을 위하여 환자의 혈액을 강원대학교 부속동물 병원에 분석, 의뢰하였다. 혈액화학검사에서 고칼슘혈증, 고질소혈증, 콜레스테롤혈증, 고인혈증, 저알부민혈증 및 대사성 산증을 보였으며 뇨검사에서 단백뇨를 동반한 약산성의 등장뇨가 관찰되었다. 임상증상과 실험실 소견에 근거하여 간과 신장에 대한 정밀한 검사를 위하여 입원을 요청하였으나 다음 날 환자는 폐사한 상태로 병원에 후송되었다. 보호자의 동의를 얻어 부검과 조직병리학적인 검사를 실시한 결과 간, 신장, 비장 등의 전신 장기에 과량의 아밀로이드가 침착되어 있음을 확인하였다.

This experiment was designed to investigate the effect of Phellodendron amurense(PLDA) on the Alzheimer's disease. The effects of PLDA extract on $IL-1{\beta}$, IL-6, amyloid precursor proteins(APP), acetylcholinesterase(AChE), glial fibrillary acidic protein(GFAP) mRNA of PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$ and AChE activity of PC-12 cell lysate treated by $A{\beta}$ plus $rIL-1{\beta}$ and behavior of memory deficit mice induced by scopolamine and mice glucose, uric acid, AChE activity of memory deficit rats induced by scopolamine were investigated, respectively. PLDA extract suppressed $IL-1{\beta}$, IL-6, APP, AChE, GFAP mRNA in PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$ ; AChE activity in cell lysate of PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$. PLDA extract increased glucose, decreased uric acid and AChE significantly in the serum of the memory deficit rats induced by scopolamine. PLDA extract group showed significantly inhibitory effect on the memory deficit of mice induced by scopolamine in the experiment of Morris water maze. According to the above results, it is suggested that PLDA extract might be usefully applied for prevention and treatment of Alzheimer's disease.

This experiment was conducted to assess the changing patterns and relative values of acute phase proteins and inflammatory cytokines in experimental caprine coccidiosis. Eighteen newborn kids were allocated to 3 equal groups. Two groups, A and B, were inoculated with a single dose of $1{\times}10^3$ and$1{\times}10^5$sporulated oocysts of Eimeria arloingi, respectively. The third group, C, received distilled water as the control. Blood samples were collected from the jugular vein of each kid in both groups before inoculation and at days 7, 14, 21, 28, 35, and 42 post-inoculation (PI), and the levels of haptoglobin (Hp), serum amyloid A (SAA), TNF-${\alpha}$, and IFN-${\gamma}$ were measured. For histopathological examinations, 2 kids were selected from each group, euthanized, and necropsied on day 42 PI. Mean Hp concentrations in groups A and B (0.34 and 0.68 g/L) at day 7 PI were 3.2 and 6.3 times higher than the levels before inoculation. The mean SAA concentrations in groups A and B (25.6 and 83.5 ${\mu}g$/ml) at day 7 PI were 4.2 and 13.7 times higher than the levels before inoculation. The magnitude and duration of the Hp and SAA responses correlated well with the inoculation doses and the severity of the clinical signs and diarrhea in kids. These results were consistent with the histopathological features, which showed advanced widespread lesions in group B. In both groups, significant correlations were observed for TNF-${\alpha}$ and IFN-${\gamma}$ with SAA and Hp, respectively. In conclusion, Hp and SAA can be useful non-specific diagnostic indicators in caprine coccidiosis.

Diarrhea is the most common cause of death in calves, and remains a major health challenge. Although there are many studies on the related pathogens, the understanding of the clinicopathological changes is limited. This study aimed to identify the pathogens and observe the clinicopathological changes in electrolytes and acute phase proteins (APPs) associated with diarrhea. Blood samples and fecal samples were collected from 141 calves for the determination of APPs, electrolyte and acid-base status and identification of enteropathogens, respectively. Single or co-infections with enteropathogens, including virus (bovine viral diarrhea virus, coronavirus, and rotavirus), Eimeria, Cryptosporidium, and Escherichia coli K99 were detected in both non-diarrheic and diarrheic calves. Levels of APPs such as serum amyloid A, haptoglobin and fibrinogen were comparable between diarrheic and non-diarrheic calves. Hypoglycemia, high blood urea, electrolytes and acid-base imbalance (hyponatremia, hypochloremia, and decreased bicarbonate), and strong ion difference (SID) acidosis showed a significant association in diarrheic calves (p < 0.01). Particularly, significant hyponatremia, bicarbonate loss, SID acidosis, hypoglycemia, and elevated blood urea nitrogen were found in rotavirus-infected calves. Monitoring the clinicopathological parameters of APPs and electrolyte levels could be vital in the clinical management of diarrheic calves.

Objectives : The oriental medicine Jangwonhwan, a boiled extract of 12 medicinal herbs/mushrooms, has been prescribed to patients with cognitive dysfunction, as originally described in the Korean medical text, DonguiBogam(amnesia chapter). Recently, a modified formula of Jangwonhwan (LMK02-Jangwonhwan) consisting of seven medicinal plants/mushrooms, was shown to reduce the ${\beta}$-amyloid deposition in the brain of Tg-APPswe/PS1dE9 mouse model for Alzheimer's disease. The toxicity of LMK02-Jangwonhwan was investigated in SD rats, by a daily oral administration for 13 weeks and NOAEL(No observed adverse effect dose), a definite toxic dose and target organ, as well. Methods : Quality control of the tablet form of LMK02-Jangwonhwan was established by estimating the indicative components, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelicagigas Nakai. The toxicity of LMK02-Jangwonhwan was investigated in 6 week old, specific pathogen free (SPF), Sprageu-Dawley rats by oral administration. Each test group consisted of 10 male and 10 female rats. The groups received doses of 500, 1,000 or 2,000 mg/kg/day of test substance for 13 weeks. The clinical signs, death rate, body weight, food consumption, ophthalmic examination, urinalysis, hematological and serum biochemistry, organ weight and pathological changes were examined and compared with those of the control group. Results : The 13-week repeated oral treatment doses didn't result in any specific symptoms or death. There were no significant changes in the rat's weight and food consumption. Further, ophthalmic examination, urinalysis, hematological, serum biochemistry test and organ weight revealed no significant differences. Conclusions : The no-observed-adverse-effect level(NOAEL) of LMK02 for male and female Sprague-Dawley rats was determined as 2,000mg/kg/day and the target organ wasn't confirmed. Because no significant adverse effects were observed, the target organ could not be determined.

The oriental medicine Jangwonhwan, which is a boiled extract of 12 medicinal herbs/mushroom, has been prescribed for patients with cognitive dysfunction and it is originally from the Korean medical text, DonguiBogam(amnesia chapter). Recently, a modified recipe of Jangwonhwan (LMK02-Jangwonhwan) consisting of seven medicinal plants/mushroom, was shown to reduce ${\beta}$-amyloid deposition in the brain of Tg-APPswe/PS1dE9 mouse model of Alzheimer disease. The toxicity of LMK02 was investigated in SD rats by oral repeated adminstration for 4 weeks and we tried to determine test does for 13 weeks repeated study. Quality control of tablet form of LMK02 was established by estimating indicative components, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelicagigas Nakai. The toxicity of LMK02 was investigated in 6 weeks old specific pathogen free (SPF) Sprageu-Dawley rats by oral administration. Each test group were consist of 5 male and 5 female and they received doses of 500, 1,000 and 2,000 mg/kg/day of test substance for 4 weeks. The clinical signs, death rate, body weight, food consumption, ophthalmic examination, urinalysis, hematological and serum biochemistry, organ weight and pathological changes were examined and compared with those of control group. Urinalysis : We observed increase of PRO(p<0.01), SG(p<0.01) in female rats of 1,000 mg/kg/day and 2,000 mg/kg/day(p<0.01). Also, we observed increase of pH and KET in female rats of 1,000 mg/kg/day(p<0.05) and of 2,000 mg/kg/day(p<0.01). WBC in female rats in 1,000 mg/kg/day and 2,000 mg/kg/day were on increase. Hematological test : We observed increase of MCV in male rats of 250 mg/kg/day. (p<0.05) Serum biochemistry test : We found increase of CHO in female rats of 2,000 mg/kg/day(p<0.05). During the experimental period, there were no animals dead or moribund. There were no treatment related changes of general symptom, food and water consumption, organ weight and autopsy According to the results of 4-week repeated dose range finding study, the highest dose was established as 1000 mg/kg for 13-week repeated dose toxicity study and we determined to put 2 more groups by common ratio two.
