Podocyte is a terminally committed cell in G1 arrest of cell cycle, and is unable to overcome G1/S transition phase in children with minimal change disease (MCD) and classic focal segmental glomerulosclerosis (FSGS), in contrast to dysregulated proliferative phenotype of idiopathic collapsing glomerulopathy (CGN) in adults. Forty-two kidney biopsies, MCD (14), FSGS (12), CGN (4), and normal (CON) (12), were evaluated by immunohistochemistry using dual staining for expression of p27, p21, and p57, and cyclins D and A, in podocytes of children with CGN. On light microscopy, all podocytes expressed p27, whereas p21 and p57 expression was seen in a …
A Comparative Study Of Steroid Hormone Levels And Oestrogen Receptor Alpha (Erα) Between Normal Bitch Uteri And Pyometra During Dioestrus, Sayamon Srisuwatanasagul, Kongkiat Srisuwatanasagul, Sudson Sirividayapong
A Comparative Study Of Steroid Hormone Levels And Oestrogen Receptor Alpha (Erα) Between Normal Bitch Uteri And Pyometra During Dioestrus, Sayamon Srisuwatanasagul, Kongkiat Srisuwatanasagul, Sudson Sirividayapong

Ovarian steroid hormones and their receptors play an important role in both physiological as well as pathological changes seen in the uterus. For the further understanding of the mechanism of pyometra, in relation to steroid hormones and their receptors in the bitch, the difference between the expression of the oestrogen receptor alpha (ERa) between normal and pyometra bitches during dioestrus was investigated. Uterine samples were collected during dioestrus from normal and pyometra bitches. Immunohistochemistry was used to investigate the expression of ERa in the different compartments of the uterus. The results showed that the levels of steroid hormones in the …

We present the morphological, immunohistochemical, and molecular genetic features of three cases of testicular and four cases of ovarian mixed germ cell sex cord-stromal tumors (MGSCT). The germ cells in the testicular MGSCTs morphologically differed from those in classical seminomas by lacking the typical "square off" quality of the nuclei. In contrast to the nuclei in classical seminomas, their size in testicular MGSCTs was smaller and nucleoli were inconspicuous and the cytoplasm was Periodic Acid-Schiff(PAS) negative. Quite on the contrary, the variability in the size of the nuclei of the germ cells in the testicular MGSCTs was more similar to …

Two commercially available automated immunohistochemistry platforms, Ventana NexES and DakoCytomation Autostainer Universal Staining System, were compared for diagnosing sheep scrapie and cervid chronic wasting disease. Both automated platforms used the same antiprion protein monoclonal primary antibodies, but different platform-specific linker and amplification reagents and procedures. Duplicate sections of brainstem (at the level of the obex) and lymphoid tissue (retropharyngeal lymph node or tonsil) from the same tissue block were immunostained for the comparison. Examination of 1,020 tissues from 796 sheep revealed 100% concordance of results between the Ventana NexES and DakoCytomation platforms for diagnosing sheep scrapie from lymphoid tissue (103/103 …

Aim: In immunohistochemistry, antibodies are used to detect and localize antigens in cellular compartments in sections taken from frozen or paraffin blocks. Currently, computerized image processing techniques are widely available to analyze immunohistochemically stained tissues; however, the image analysis programs are generally highly specific and expensive. We aimed to show the feasibility of computer assisted image analysis (CAIA) by using two computer programs currently in widespread use. Methods: Two available computer programs, Adobe Photoshop CS and ImageJ, were used to separate areas in the same tissue sections stained with NOS antibody and labeled with peroxidase in human endometrial tissue. CAIA …

Systemic candidiasis is a rare disease of animals. In this study, the clinical course, and cultural and pathological findings of systemic candidiasis are described and presumed predisposing factors are investigated in 3 dogs. Pathologically, pyogranulomatous lesions in various organs were present in all dogs. Blastospores, pseudohyphae, and true hyphae of Candida albicans were observed with periodic acid Schiff, Gomori's methenamine silver, and immunohistochemistry. Administrations of broad-spectrum antibiotics and corticosteroids and, in one dog, parvoviral infection were thought to be predisposing factors leading to opportunistic infection. The combined effect of immunosuppressants and antibiotics might have led to Candida colonization and dissemination …
