A new report on the occurrence of clinico-histopathological diagnostic criteria for Spinodiplotriaena.

Parasitic diseases of wild birds follows its companion volume, infectious diseases of wild birds, both of which complement the third edition of infectious diseases of wild mammals and second edition of parasitic diseases of wild mammals. In October 2012, a mature black male mynah with lack of balance and ataxia was brought into the birds department of educational hospital in veterinary medicine faculty of Tehran University. Because of no cure in clinical signs after several days of empirical therapy euthanasia and clinical pathology studies were performed. There was no microscopic pathological lesions in brain, bone marrow, heart, lung, liver and the microscopic results were as following; bone marrow: hemophagocytosis reactive macrophages, liver: infiltration of inflammatory cells (hepatitis) and hemosiderin-laden macrophages. Lung: hemosiderin-laden macrophages and spleen findings: infiltration of inflammatory cells, heterophils with phagocytic bacteria. In abdominal cavity two male and one female parasite was detect. Three parasites were cleared with lactophenol and investigated under the light microscopy and important morphological parts of them measured. Also these parasites in serum containing send to the department of parasitology. Based on all collecting data, Spinodiplotriaena (three parasites each by the length of 2/5, 1/7 and 1/5 cm were found) were diagnosed. Report of this case in important because of first report of this infection in a black mynah in Iran.

An overall assessment of circumanal gland adenoma in a terrier mix breed dog.

In September 2012, a 10-year-old, intact male, terrier mix breed dog was evaluated because of multiple, 0.5 to 1.2 cm in diameter, round, intradermal nodules around the anus. It had surgery to excise a firm, painful swelling in the left ventrolateral perianal region and the excision part was observed under light microscopy. The mass spreading in to sub acute was of left hind leg out from the ventro-lateral of anus, 1.2 cm×1 cm/ 0 cm×0.5 cm in size and 125 g in weight. A complete blood cell count, serum biochemistry panel, and urinalysis (cystocentesis sample) were evaluated. Significant laboratory data demonstrated microcytic anemia (hemoglobin of 6.4 mg/dL) and normal coagulation times. No remarkable abnormalities were found in the complete blood count and an ionized calcium of 1.91 mmol/L (reference range, 1.1-1.3 mmol/L) was confirmed hypercalcemia. On cytologic and histopathologic examinations, evaluation of the aspirate revealed a prominent population of round-to-polygonal nucleated cells arranged as cohesive groups with isolated individual cells. A mild degree of anisocytosis and anisokaryosis was observed. In addition, smaller reserve type cells, with darker cytoplasm and a higher nucleocytoplasmic ratio. The adenomas generally retain the lobular architecture, but some may contain focal areas of cellular pleomorphism. These changes may suggest malignant transformation and have led to discordant interpretations, the well-developed stroma surrounding the lobules and hepatoid cells was noted. Ulceration, hemorrhage, necrosis and secondary infection with inflammatory cell infiltrates are common. These cytology and histopathology features are consistent with hepatoid gland adenoma.

Evaluation of an anal sac adenocarcinoma tumor in a Spitz dog.

A 9-year-old emasculated male Spitz with tenesmus and constipation had a subcutaneous mass at the left ventral aspect of the anus with history of polyuria and polydipsia. A complete blood cell count, serum biochemistry panel, and urinalysis (cystocentesis sample) were evaluated. Abnormalities in the serum biochemistry panel included a mildly elevated serum cholesterol concentration (7.28 mmol/L; reference interval, 2.70-5.94 mmol/L), increased serum alkaline phosphatase activity (184 U/L; reference interval, 9-90 U/L), alanine transaminase (122 U/L; reference interval, 5-60 U/L) activity and aspartate aminotransferase (80 U/L; reference interval, 5-55 U/L) activity, severe increased total calcium concentration (16.3 mg/dL; reference interval, 8.2-12.4 mg/dL or 9.3-11.4 mg/dL), and decreased total calcium concentration (3.4 mg/dL, reference interval, 2.5-5.6mg/dL). Furthermore, testing revealed an increased intact parathyroid hormone concentration (38.6 pmol/L; reference interval, 3-17 pmol/L). On cytologic and histopathologic examinations, various types of cells were observed. Most of the cells were oval to polygonal and had elliptical or elongate nuclei and a moderate amount of pale to basophilic cytoplasm. The remaining cells had round to oval nuclei and pale to basophilic cytoplasm. Cells of both types were loosely adhered to each other and were arranged in rosette-like structures. Both neoplastic cell types had fine homogenous chromatin and either a small indistinct nucleolus or no visible nucleolus. Mild anisokaryosis and anisocytosis were observed. Histologically, the mass consists of glandular structures formed by cuboidal cells admixed with bundles of spindle cells. Based on location and histologic features, the final diagnosis was adenocarcinoma of the apocrine gland of the anal sac, which should be included as a cytologic differential diagnosis when spindle cells and typical epithelial cells are observed in masses in the region of the anal sac of dogs.

Study on analgesic and anti-inflammatory properties of Cordia myxa fruit hydro-alcoholic extract.

Cordia myxa is a plant which is used in tropical regions of the world. Analgesic and anti-inflammatory effect of fruit of this medicinal plant was investigated in mice. Hydro-alcoholic extract of it was prepared by maceration method. Formalin test was conducted in six groups of mice (6 animals in each group) and acetic acid test in another six groups (6 mice). Groups one to six in each test were administered normal saline, oral indomethacin, intraperitoneal tramadol, 100 mg kg(-1) oral extract, 200 mg kg(-1) oral extract and 100 mg kg(-1) intraperitoneal extract, respectively. The duration of foot lickings were calculated in formalin- administered (1st) group within min 0 to 5 (acute phase) and 15 to 25 (chronic phase). Acetic acid-induced writhings were counted within 10 min in the 2nd group. The results showed that hydro-alcoholic extract of Cordia myxa fruit was considerably effective in formalin test. Also, analgesic and anti-inflammatory properties of this plant's fruit in both acute and chronic phase are somewhat similar to these properties in the study on animal model of experimental colitis.
