  • A necrotizing skeletal myopathy was diagnosed in three flocks of 30,000 thirty-eight-week-old layer breeder chickens. The mortality attributed to the myopathy was 17.7%, 12.3% and 21.1% in flock A, B and C, respectively. Clinically, chickens were showed depression, anorexia, posterior paresis, inability to rise, incoordination, reluctance to move, and leg trembling and weakness. The most striking findings at necropsy was pale streaking in the muscles of the thighs and legs. Microscopic lesions included myofiber degeneration and necrosis with massive cellular proliferation interpreted as sarcolemmal nuclei proliferation. Plasma creatine kinase, asparte aminotransferase and akaline phosphatase were markedly elevated. In conclusion, author suggested that submitted chickens were affected by ionophores poisoning.

  • Verruca vulgaris is one of the most frequent lesions of the skin. Evidences support that this lesion has strong association with low-risk human papillomavirus. Unlike skin lesion, oral verrucae vulgaris are not easily encountered and often misdiagnosed as squamous papilloma. Herein, we reported eight cases of oral verruca vulgaris and analyzed their clinicopathological features.

  • Ameloblastomas are benign epithelial neoplasm of the jaw comprising approximately 1-3.3% of all odontogenic cysts and tumors. Although most are microscopically benign, they are generally considered to be locally aggressive and destructive, exhibiting a high rate of recurrence. Treatments of them contain the conservative treatments on unilocular types and radical treatments on multilocular types. Classifications based on the histologic features of ameloblastoma generally included the follicular, plexiform, acanthomatous, basal cell, uncystic types. However, recently a new and unusual variant has been added by Eversole et. al in 1984, the histologic features of which are characterized by marked stromal desmoplastic proliferation. This is a case report of desmoplastic ameloblastoma in the anterior maxilla of 63 year-old female treated by block excision. This provides a brief review of the literature because of the rarity and unusual radiographic-histologic features of desmoplastic ameloblastoma.

  • Five dogs with renal failure were referred to the Veterinary Medical Teaching Hospital at Kangwon National University. These dogs had the common history of consumption of Pedigree dry dog food produced in Thailand plant for over 1 month. The dogs showed anorexia, emaciation, vomiting, and polydipsia/polyuria. And in one severely affected dog, bloody diarrhea and hypothermia were seen. The remarkable clinicopathological signs were high value of BUN and creatinine. In some dogs, GGT, phosphorus and lipase were increased. However, no significant changes of complete blood count were found. In urinalysis, hematuria, low specific gravity urine, proteinuria, and calcium oxalate-like crystals were observed. Two severely affected dogs were died. The remained dogs were recovered gradually after change of dog food and supportive therapy. Pathological findings were seen typically in kidneys. Renal atrophy, congestion of the glomerular capillary, and diffuse degeneration, necrosis, dystrophic calcification and regeneration in the tubular epithelium were seen. Yellowish brown fluorolucent laminated materials or particles were quite often found in the lumina of the necrotizing renal tubules of cortex and medulla. Proliferation of fibrous tissue in the interstitium was also seen. By the mycotoxin analysis of the Pedigree dry dog food, ochratoxin A (OTA) and citrinin were detected as much as the concentration of 372.8 ppb and 8.3 ppb, respectively. The final diagnosis of renal failure caused by OTA and citrinin toxicosis was made on the basis of history takings, clinical signs, clinicopathological and pathological findings, and analysis of mycotoxins.

  • Purpose: The aim of this study was to compare synchronous and metachronous hepatic metastases in patients with gastric cancer to determine clinicopathologic features and differences in prognosis as a function of the timing of the metastasis and the treatment modality rendered. Materials and Methods: Sixty-seven patients who were diagnosed with gastric cancer metastatic to the liver and treated at the Hanyang University Hospital between June 1992 and December 2006 were retrospectively analyzed to study the pertinent clinicopathologic features and effect of treatment methods. Results: There was a significant difference with respect to lymphatic (P=0.041) and vascular invasion (P=0.036) in comparing the clinicopathologic features between the patients with synchronous and metachronous hepatic metastases. The 1-year survival rate and median survival time of patients with gastric cancer and liver metastases were 38.9% and 9.2 months in the entire patient cohort, 30.9% and 9.2 months in the synchronous group, and 44.5% and 9.7 months in the metachronus group, respectively (P=0.436). The group of patients undergoing local treatment (such as surgery and radiologic intervention) followed by systemic chemotherapy, the group of patients receiving systemic chemotherapy only, and the untreated group of patients were compared, and there was no difference between the synchronous and metachronous groups. The synchronous and metachronous groups had high survival rates with local treatment. Conclusion: In patients with gastric cancer and liver metastases, there was no difference in prognosis based on the timing of the hepatic metastases. Independent of the timing of hepatic metastasis, aggressive treatment, such as surgery and radiologic intervention, may help improve the prognosis.

  • Investigation on health conditions of Thai koi (Anabas testudineus) were carried out through clinical and histopathological observations from different farms of Mymensingh district for seven months during August 2006 to February 2007. Fish sampling and water quality parameters (temperature, dissolved oxygen and pH) were monitored on a monthly basis. Clinical examination of fishes was also carried out for any kind of abnormalities at monthly intervals. Samples of skin, muscle, gill, liver and kidney were observed by histological technique. Among the water quality parameters the values of water temperature, dissolved oxygen were found to be at unfavorable level for fish during the colder months in the farms. Clinically it was observed that fishes were more affected from December to January and almost normal in appearance during August to September and February. Different clinical symptoms like scale loss, dermal lesion, ulcer and loss of caudal fin were noticed in December and January. In histopathological study, structures of fish organs were normal from August to September. In the months of October and November, minor pathologies were found to be started. Marked pathological changes like necrosis, pyknosis, inflammation, hemorrhage, hypertrophy, hyperplasia, missing of primary and secondary gill lamellae were observed in the months of December and January. Whereas, in the month of February the pathological condition of fish gradually reduced. Again when considered individual fish farm, fishes of Reliance Aqua Farm were more affected than Sotota Matshya Hatchery. The study showed that severity of clinical and pathological changes were increased in December and January. During the period EUS and protozoan diseases were noticed in A. testudineus of the investigated farms.

  • Purpose: Superficially spreading (SS) early gastric cancer (EGC) is characterized by wide horizontal extension without deep vertical invasion. It is a relatively rare form of EGC, and it's clinicopathological (C-P) characteristics are not evident. This study aimed to clarify their C-P characteristics. Materials and Methods: We defined SS EGC as invading less than the submucosal layer that measured more than 60 mm in diameter or wider than $5{\times}5cm \;(25cm^2)$ in width. The C-P characteristics and prognosis were compared between 69 patients with SS EGC and 319 patients with the common type EGC (EGC except SS type). Results: For SS EGC lymph node metastases, Lauren's diffuse type, lymphatic invasion were significantly higher than in common type EGC. In patients with SS EGC, all of the metastatic lymph nodes were anatomically distributed within the paragastric region, with fewer along the left gastric artery and common hepatic artery. In 6 cases of SS EGC with resection marqins less than 10 mm, there was no death during the follow-up period (4 to 13 years after operation) if margins were not involved. Age (>58 yrs), tumor site (upper 1/3), lymph node metastasis, submucosal invasion were statistically significant poor prognostic factor in univariate survival analysis. In multivariate survival analysis, age and lymph node metastasis were independent prognostic factors. However, tumor diameter or width was not a significant prognostic factor. Conclusion: Although SS EGC has histologically distinct properties, gastrectomy with free surgical margins and appropriate lymph node dissection $(D1+{\beta})$ could be a suitable treatment.
