Present experiments were undertaken in order to find out the most available diagnostic method for acute pancreatitis. Experimental dogs were divided into experimental group and control group. The experimental dogs were laparotomized and their pancreatic ducts were ligated for the induction of pancreatitis. The control dogs were laparotomized only for comparison. In addition to the complete blood count, serum amylase and lipase activities, serum glucose, total protein and albumin contents were measured daily for 11 days after the operation. Fecal fat droplet count by Sudan III staining and fecal trypsin activity examination by x-ray film digetion test were also undertaken daily. The results obtained were summarized as follows; 1. Serum amylase activities of the experimental group increased to peak on the third day and returned to the preoperative values on the eighth day. 2. Serum lipase activities of the experimental group increased to peak on the first day and returned to the preopertive values within six to eight days. 3. Serum glucose contents of the experimental group showed significant increse only on the first day. 4. Serum albumin contents of the experimental group decreased significantly during the experimental period. Whereas those of the control group significantly decreased only on the first day. 5. The experimental group showed marked leukocytosis, neutrophilia, and lymphopenia for the first 5 or 8 days. Whereas the control group showed only neutrophilia for the first 3 days. 6. The results of fecal fat droplet count showed some diagnostic value on the third and fourth day in only one experimental dog(No 1). No significant changes in the fecal trypsin activity were noticed in all dogs. 7. Histopathologically. all dogs of experimental group showed changes of pancreatitis. However the degree of the pancreatic lesion was not pararell to the degree of the serum amylase or lipase activity changes.

Reference interval is critical for interpreting laboratory results, monitoring response to therapy and predicting the prognosis of the patients in clinical settings. The aim of the present study was to update established reference intervals for routine hematologic and serum chemistry values for a population of clinically healthy dogs (range, 1-8 years) seen in an animal hospital. Blood was obtained by venipuncture while animals were physically restrained, and samples were analyzed for 9 chemistries on MS9-5H (Melot Schloesing Lab, France) and 6 hematology on Vet Test 8008 (IDEXX, USA). Data from 105 dogs (52 males and 53 females) for hematology and 113 dogs (37 males and 76 females) for chemistry were used to determine reference intervals using the parametric, nonparametric and bootstrap methods. Prior to analysis, all parameters were tested for normal distribution using Anderson-Darling criterion. Of the 9 biochemical analytes, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, creatinine, total protein, and glucose concentrations did not fit normal distribution for both original and transformed data. All but eosinophil count satisfied normal distribution for either original or transformed data. Parametric method can be used for original cholesterol concentrations, RBC, WBC, and neutrophil counts. This technique can also be used for power-transformed values of blood urea nitrogen concentrations and for logarithm of lymphocyte and monocyte counts. Non-parametric or bootstrap method was the preferred choice for the remaining 7 biochemical parameters and eosinophil count as they did not follow normal distributions. All three statistical techniques performed in similar reference intervals. When establishing reference intervals for clinical laboratory data, it is essential to assess the distribution of the original data to increase the accuracy of the interval, and non-parametric or bootstrap methods are of alternative for the data that do not fit normal distribution.

Agkistrodon halys (Crotalidae) is the only species of poisonous snakes in Korea, and is divided into three subspecies; Agkistrodon bromhoffii brevicaudus, Agkistrodon calaginosus and Agkistrodon saxatilis. With the three venoms, the pharmacological actions on the cardiovascular system and intestine as well as some toxicological characteristics were studied. In addition, the precipitin test in an agar gel medium was employed for immunological comparison of the venoms and the sera of envenomed patients. The results obtained were as follows: Lyophilized venoms contained solids of $211{\sim}273mg/ml$, and LD50 to mice were 1.73 and 0.86 mg/kg in venoms of Agkistrodon bromhoffii brevicaudus obtained on July and October respectively, and 0.40 and 0.32 mg/kg in Agkistrodon calaginosus and the venoms of Agkistrodon saxatilis obtained on October was 2.29 mg/kg. Isoelectric focusing of lyophilized snake venoms showed 19 to 22 protein fractions and 2 to 3 isoamylase fractions. Acute irreversible hypotension was caused by the intravenous injection of large doses of venoms in rabbits and cats, but at the small doses, acute hypotension followed by slow recovery. Little changes of cardiac movements by the venom injection despite of marked hypotension were showed except bradycardia and arrhythmia prior the death. Also no changes on the isolated rabbit atria by the snake venoms were noted. The hypotensive effect of the snake venoms was prevented by the bilateral vagotomy or atropine pretreatment (1 mg/kg), but they did not affect when already the hypotension has undergone. In the isolated rabbit duodenum, small doses of venom increased the phasic movement, while large doses decreased after spastic contraction. With the injection of venoms in dog, strong contraction of gall-bladder was caused and it was not blocked by the pretreatment with phenoxybenzamine (10 mg/kg) or atropine (1.4 mg/kg). In the venoms of Agkistrodon bromhoffii brevicaudus and Agkistrodon calaginosus, at least 5 antigenic components were detected, and four of them were shared in common with each other. Polyvalent antivenin (Wyeth Lab. USA) had three common precipitating antibodies with the venom of Agkistrodon bromhoffii brevicaudus and Akistrodon calaginosus. In the serum of envenomed patients, no precipitating antibodies were seen to the venoms and little changes in serum protein, GOT and GPT were observed. In conclusion, the snake venoms obtained in Korea were highly toxic and caused chiefly the vascular collapse leading to death. This vascular collapse was resulted largely by cholinergic effects, and not cardiotoxin of venoms. In human, it is likely that precipitating antibodies to venom were not produced by an envenomed incidence to poisonous snakes.

혈청검사항목의 해석기준으로 사용하는 참고범위는 측정 장비와 병원마다 차이를 보이기 때문에 병원 간 정보를 교환하고 해석하는데 어려움이 많다. 또한 동일한 병원에서도 내원한 환자의 특성을 고려하여 참고범위를 재설정하는 것이 일반모집단의 특성을 제대로 반영한다. 본 연구에서는 강원대학교 수의학부대학 동물병원에서 설정한 혈청화학 검사 항목의 참고범위를 재평가하기 위하여 2005-2006년 동안 본원에 내원한 임상적으로 건강한 개 100두(1-8세, 체중 2.2-5.8 kg)의 혈청검사 일부 항목을 모수 및 비모수적 bootstrap 모의시험으로 분석하였다. 평가항목은 BUN(mg/dl), cholesterol(mg/dl), calcium(mg/dl), aspartate aminotransferase(AST, U/L), alanine aminotransferase(ALT, U/L), alkaline phosphatase(ALP, U/L) 및 total protein(g/dl)으로 Ektachem DT 60 분석기(Johnson & Johnson)로 측정하였다. 칼슘을 제외한 모든 항목이 왜곡이 매우 심한 분포를 보였으며 특히 혈청 효소항목의 outlier는 전체 자료의 5-9%, 기타 항목은 1-2%를 보였다. 각 항목의 분포에 상관없이 모수적 방법에 비하여 비모수적 방법으로 추정한 참고범위가 임상적으로 유용하였으며 추정된 참고범위는 BUN 14.7(7.0-24.2), cholesterol 227.3(120.7-480.8), calcium 10.9(8.1-12.5), AST 25.4(11.8-66.6), ALT 25.5(11.7-68.9), ALP 87.7(31.1-240.8), and total protein 6.8(5.6-8.2)로 나타났다. 이러한 결과는 모집단의 특성을 고려하여 참고범위를 재설정하는데 비모수적 모의시험이 매우 유용하며 특히 측정항목의 분포에 무관하게 사용할 수 있는 장점이 있는 것으로 사료된다.

This study was performed to compare propofol, thiopental, etomidate and diazepam plus ketamin as induction agents for the isoflurane anesthesia in dogs. Experimental groups were divided into low groups (thiopental group: thiopental 15 mg/kg IV, propofol group: propofol mg/kg IV, etomidate group: etomidate 1.5 mg/kg IV, DZP+KET group: diazepam 0.5 mg/kg + ketamine 5 mg/kg, IV) and each group was consisted of 4 dogs. Cardiorespiratory changes (heart rate, $SpO_2$, respiratory rate, End-tidal $CO_2$ and body temperature), blood serum chemistry values (alkaline phosphatase, alanine aminotransforase, and total protein), and recovery and walking time were measured. The end tidal carbon dioxide level was significantly increased in the thiopental group (P<0.05). Heart rate and respiratory rate higher in the DZP+KET groups. There was hypothermia in all groups and significant decrease in body temperature was showed in thiopental group (p<0.05). Mean arousal time and mean walking time were significantly longer in thiopental group (P<0.05). Cardiovascular stimulating effects were minimal in etomidate group. Etomidate provides uneventful and rapid recovery.

Cystatin C is a low molecular weight 13 kilodalton protein. It is known to be a more sensitive marker of glomerular filtration rate than creatinine in humans. The purpose of the present study was to demonstrate the changes of renal markers including cystatin C according to the severity of chronic mitral valve insufficiency (CMVI) and to investigate the clinical relevance of cystatin C as an early renal marker in dogs with CMVI. A retrospective study was performed to assess renal function according to International Small Animal Cardiac Health Council (ISACHC) system classification of heart failure in dogs with CMVI. Thirty seven dogs were divided into a group 1 (healthy dogs ; n = 10), a group 2 (ISACHC I ; n = 10) and a group 3 (ISACHC II-III ; n = 17). In all dogs, serum concentrations of bun (sUr), creatinine (sCr) and cystatin C (sCys-C) were measured with an automated analyzer. In dogs with CMVI, sCys-C concentrations were significantly correlated with sCr concentrations and were independent of age, BW, SBP, and sex. Renal dysfunction tended to occur more frequently as the severity of CMVI increases. In dogs with mild CMVI, only sCys-C concentrations were statistically higher than in healthy dogs. This study demonstrates the clinical relevance of sCys-C. sCys-C may be a valuable renal marker for early diagnosis of renal dysfunction in dogs with CMVI.

This study aimed to determine the effect of feeding Hermetia illucens (H.illucens) pellets with canine diets on fecal properties and digestibility. The canine breeds used in this experiment were nine dogs without discriminating between genders: 3 Maltese (average weight 2.0 kg), 3 Chihuahua (average weight 1.0 kg), and 3 Poodles (average weight 2.5 kg). As canine diets, 70 g of regular diets were mixed with 30 g of H.illucens pellets, and 100 g was weighed on a scale. Dog were fed the experimental diets once a day. No significant changes were observed in the fecal properties in the three types of canines fed a mixture of pellets and canine diets at Days 0 and 7 (p>0.05). At Day 0, the fecal properties of all canines appeared in a less solid state, with scores ranging from 2.00 to 2.22; however, at Day 7, the fecal properties improved to normal (3.00 to 3.33). In addition, the results for nutrient digestibility showed that dry matter and crude fat digestibility were significant (p<0.05); however, crude protein and crude ash digestibility were not affected (p>0.05). In conclusion, these results suggest that feeding a mixture of H.illucens pellets and canine diets to companion canines has beneficial effects on fecal properties and digestibility without adverse effect.

본 연구는 tiletamine/zolazepam 대조군과 대조군에 benzodiazepine의 길항제인 flumazenil을 투여한 실험군의 마취 효과와 혈액생화학, Vital sign, 마취회복시간에 대하여 비교하였다. 건강한 6마리의 개들(평균 체중 $5.2{\pm}2.2$)이 실험에 이용 되었다. Tiletamine/zolazepam 을 투여하였고 20분 뒤에 benzodiazepine의 길항제인 flumazenil 0.1 mg을 투여하였다. 마취효과 (Sedation, analgesia, muscle relaxation, posture and auditory response score), Vital sign (심박수, 호흡수, 체온), 혈액 생화학 (GLU, TP, ALT, AST) 검사들이 두 그룹에서 tiletamine/zolazepam 투여전, 투여후 1, 5, 20, 30, 60 그리고 90분에 실시되었다. 또한 마취회복시간 (head up, sternal recumbency, standing and walking times)은 부동화 상태에서 각 행동양식 이 보이는 시간까지 측정되었다. Analgesia score는 투여 후 20분과 30분에, posture score는 투여 후 30분에 그리고 auditory response score는 투여 후 1분과 20분에 TZF그룹이 TZ그룹보다 유의하게 낮아 benzodiazepine에 대한 flumazenil의 길항효과를 나타냈다. 평균 심박수는 두 그룹 모두 투여 후 1분부터 급상승하여 유의하게 정상 심박수 보다 높았다. 평균 호흡수는 TZF그룹이 TZ그룹보다 유의하지 않았으나 높은 호흡수를 보였다. 결론적으로 개에서 flumazenil의 투여는 tiletamine/zolazepam에 대한 길항작용을 나타내었다. 마취로 부터의 회복에 있어서, flumazenil은 sternal recumbency, standing 및 walking times를 단축시켰다.
