Abstract

The present investigation describes the spontaneous pathological lesions in urinary bladders (n = 177) of slaughtered buffaloes collected from Northern India. Gross examination revealed congestion, haemorrhages, oedematous changes and thickening of mucosa. Microscopically, epithelial abnormalities, inflammatory and neoplastic conditions were noticed. Epithelial abnormalities included epithelial hyperplasia, von Brunn’s nests, cystitis cystica and cystitis glandularis. Inflammatory conditions such as congestion, haemorrhages and cystitis were noticed. Cystitis was classified as lymphocytic, plasmo-lymphocytic, follicular and interstitial types. However, only single case of haemangiosarcoma was observed. Polymerase chain reaction revealed the presence of DNA of only BPV-1 in one sample out of 21, while one sample showed the presence of DNA of both BPV-1 and BPV-2. On immunohistochemistry, Ki-67 expression was observed only in haemangiosarcoma and one case of plasmo-lymphocytic cystitis with immunostaining restricted to nuclei. COX-2 immunostaining was observed in one case each of flat hyperplasia, von Brunn’s nest, haemangiosarcoma and two cases of plasmo-lymphocytic cystitis. Among epithelial abnormalities, COX-2 immunostaining was restricted to epithelial component of the lesions, and it was diffused cytoplasmic type with occasional perinuclear staining particularly in the cytoplasmic membrane. However, in haemangiosarcoma the COX-2 immunoreactivity was noticed in epithelial as well as connective tissue stroma. In conclusion, it may be stated that urinary bladders of slaughtered buffaloes showed a number of epithelial abnormalities, inflammatory conditions and occasionally neoplasms. Further studies to explore the infectious as well as non-infectious etiologies should be undertaken.

印度水牛自发性膀胱病变的病理学研究
本研究描述了在印度北部采集的屠宰水牛膀胱(n = 177)的自发性病理病变。大体检查显示充血、出血、水肿改变及粘膜增厚。显微镜下可见上皮异常、炎症和肿瘤情况。上皮异常包括上皮增生、冯·布伦氏巢、囊性膀胱炎和腺性膀胱炎。炎症情况如充血、出血和膀胱炎被注意到。膀胱炎分为淋巴细胞型、浆淋巴细胞型、滤泡型和间质型。然而,只观察到一例血管肉瘤。聚合酶链反应显示,21份样品中只有一份样品中存在BPV-1的DNA,而一份样品中同时存在BPV-1和BPV-2的DNA。免疫组化显示Ki-67仅在血管肉瘤和1例浆淋巴细胞性膀胱炎中表达,免疫染色仅限于细胞核。扁平增生、冯布伦氏窝、血管肉瘤各1例,浆淋巴细胞性膀胱炎2例,均行COX-2免疫染色。在上皮异常中,COX-2免疫染色仅限于病变的上皮成分,且为弥漫性细胞质型,偶有核周染色,特别是在细胞质膜上。然而,在血管肉瘤中,COX-2免疫反应在上皮和结缔组织间质中被注意到。综上所述,屠宰水牛的膀胱显示出许多上皮异常、炎症状况和偶尔的肿瘤。应进行进一步的研究,以探讨传染性和非传染性病因。
