The development of new investigative technology and the changing roles of other biological and medical disciplines will result in major changes in the way veterinary pathology is practiced in the future. Unless the pathologists strategically prepare themselves to adopt and incorporate these changes into their modest operandi, the veterinary pathologist's traditional dominance in the diagnosis of spontaneous animal diseases and experimentally induced lesions in animals will be at risk. Although the distinguishing feature of pathologist is their artful ability to read and interpret the pathologic changes of cells and tissues, we must strive to enhance and expand our ability beyond and above the simple reading of H&E stained slides. Also, we must be prepared to meet the ever increasing demand of diagnostic accuracy and timeliness. To do so, we have to employ the new biological and toxicological technologies into our routine.

In domestic rabbits, pasteurellosis is a primary respiratory disease entity caused by Pasteurella multocida. Respiratory pasteurellsos in rabbits is highly contagious due to dissemination of the organism in the nasal discharge (Benirschke, et al., 1978). The disease reflects a varied and complex host-parasite relationship. Acute infection with high mortality occurs sporadically especially in stressed rabbits less than 10 weeks old, in the form either an enzootic pneumonia, infection of the upper respiratory tract or septicemia. In addition to respiratory form, infection with P. multocida results in a variety of disease processes in rabbits including rhinitis, otitis media, otitis interna, abscesses, metritis, orchitis and meningoencephalaitis (Manning et al., 1989). The deleterious effects of pasteurellosis are common and pose serious problems for rabbit breeders and researchers (Flatt, 1974). (omitted)

Most renal diseases progress by consecutive cell responses such as hypertrophy, hyperplsia, proliferation, defferentiation, sclerosis, fibrosis and other cellular degenerative process. These cellular responses are mediated by the activation of various mitogens such as vasoconstrictors, growth factors, hormone, genotoxins and cytokines through mechanical, hemodynamic, immunological injury as well as metabolic abnormality.

The objective of this investigation was to evaluate of influence of gestational age at exposure on the prenatal effects of gamma-radiation. Pregnant ICR mice were exposed to single dose of 2.0 Gy gamma-radiation at gestation days from 2.5 to 15.5 days post-coitus. The animals were sacrificed on day 18 of gestation and the fetuses were examined for mortality, growth retardation, change in head size and any other morphological abnormalities. The only demonstrable effect of irradiation during the pre-implantation period was an increase in prenatal mortality. (omitted)

We performed this study to determine the effect of Bu-Zhong-Yi-Qi-Tang, as a prescription of traditional Oriental medicine, and its major ingredients on jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells of mice irradiated with high and low dose of r-radiation. Bu-Zhong-Yi-Qi-Tang administration before irradiation protected the jejunal crypts (p<0.0001), increased the formation of endogenous spleen colony (p<0.05) and reduced the frequency of radiation-induced apoptosis (p<0.05).

A case of renal candidiasis is reported in a 4-year-old male Masked Palm civet (Paguma larvata). On necropsy, the kidneys were bilaterally swollen, pale and had numerous 1 to 3 mm diameter white foci throughout the parenchyma on cut section. The urinary bladder was filled with opaque and milky exudate. Histologically, severe infiltration of neutrophils and macrophages and necrosis were noted in the interstitial areas of both cortex and medulla and in the lumens of renal tubules and collecting duct often resulting in cystic dilation of the tubules.

A case of leiomyosarcoma is reported in a 9-year-old female Jin Do. The dog has been suffered from 1 week history of abdominal distension, dyspnea, depression and anorexia. On routine physical examination, radiology and ultrasound, a large occupying mass was noted in the reptroperitoneum. Due to poor prognosis, the uterine mass removed by ovariohystrectomy and submitted to pathology department for diagnosis. Grossly, the mass was firm, tan and contained several areas that were necrotic and hemorrhagic. (omitted)

A case of mammary gland adenocarcinoma is reported in a 22-year-old female Mandril (Mandrillus sphinix). The veterinarian noted a fast growing mass, which was inflammed and perforated, involving both mammary gland during the last 4 months. Supplement antibiotic and chemotherpay were unsucessful and the monkey was found dead. On necropsy, both right and left mannary gland were replaced by firm, tan, perforating neoplastic mass.

N. caninum infections have been associated with neonatal paresis as well as abortion around the world. Bovine abortion induced by N. caninum was first reported in 1997 in Korea. Diagnosis of N. caninum infection is usually based on histopathology and immunohistochemical detection of organism. However, often the tissues having lesion suggestive of N. caninum infection were negative on immunohistochemistry. (omitted)

The consumption of cruciferous vegetables such as cabbage and broccoli have been shown to have a chemopreventive effect in human and in experimental animals. Indole-3-carbinol (I3C), one component of cruciferous vegetables, has been shown to exert its chemopreventive effect in liver, colon and mammary tissue before or concurrent exposure of carcinogen, but in some reports, there have been several evidence that consumption of I3C after carcinogen treatment induced tumor promotion in some tissues. There have been no reports about the effect of I3C after carcinogen exposure in N-Nitroso-N-methylurea (MNU)-induced mammary tumor model of rats. (omitted) -
랫드의 치아에서 발생하는 종양에는 에니멜모세포종 (ameloblastoma), 에나멜모세포성 치아종 (ameloblastic odontoma), 치아종 (odontoma) 이 있다 . 에나멜모세포종은 상피종양으로서 법랑질(enamel), 상아질 (dentin) , 시멘트질 (cementum) 을 형성하지 않는다 . 대부분의 에나멜모세포종은 소포성 (follicular) 성장이나 얼기상 (plexiform) 성장방식을 띠게 된다. 에나멜모세포성 치아종(ameloblastic odontoma) 은 치조직 종양으로서 에나멜모세포종 같이 연조직으로 된 부분과 치아종 (odontoma) 처럼 상아질, 법랑질, 시멘트질과 같은 단단한 부분으로 구성되어 있다.

Postweaning Multisystemic Wasting Syndrome (PMWS) is a recently described disease of growing pigs characterized by progressive weight loss and chronic pneumonia. PMWS was first identified in western Canada in 1995, and has now been diagnosed in the US, Europe and Asia. Since 1999, 57 pigs from 23 farms of PMWS have been diagnosed in the National Veterinary Research and Quarantine Service (NVRQS). The most common age of onest was clustered around 6-week age.

Intestinal adenocacinomas are uncommon in dogs, and they occur most frequently in the colon and rectum of animals averaging 8-9 years old. Also, they have been reported rarely in cattle, goats, horses and swine. This tumors occur slightly higher in males than in females. Boxers, collies, poodles, and German shepherds are prediposed.

Hepatic fibrosis/cirrhosis is characterized by increased production and deposition of collagen, noncollagenous glycaproteins, and proteoglycans, which mainly compose the extracellular matrix (ECM). Recently, activations of macrophages, myofibroblasts and mast cells are thaught ta be associated with the accumulation of ECM. In order to investigate the kinetics of macrophages, myofibroblasts and mast cells and the relationship between these cells and the accumulation of ECM in carban tetrachloride (CCl
$_4$ )-injected rat liver, we induced liver cirrhosis of rat by an injection of CCl$_4$ for 14 weeks. (omitted) -
최근 원전주변지역을 중심으로 한 기형가축이 발생함에 따라 이의 원인을 규명하기 위하여 우선 역학적 조사와 혈청학적 검사 및 기형송아지 , 유산·사산 태아 등의 수집가 검물을 중심으로 하여 병리학적 검사를 실시하였다. 원전주변 기형우 발생농가의 역학적 조사와 모우의 임상적 소견에서는 하동의 이상을 관찰할 수 없었다 . 수집된 가검물 (울진원전주변지역 : 3두, 월성원전주변지역 : 3두, 고리원전주변지역 : 3두, 기타지역 2두) 총 11개 농가 11두에 대한 병리학적 검사와 모우 및 자우의 혈청학적 검사에서 9두가 Akabane 병으로 진단되었고, 나머지 2 두는 곰팡이감염증 1두 그리고 간경화 l 두로 판정되었다. Akabane virus에 감염된 9두는 기형송아지, 유·사산태아로서 사지기형, 척추만곡 및 중추신경계이상(대뇌결손, 뇌수두증)등이 관찰되었다. (중략)
