Retrospective study on the cytological exams in a veterinary technic hospital in a five year period

The cytological exam is a practical diagnostic aplication which allows the detection of inflammatory, proliferative and infectious disturbances. In the present study, the results of cytological exams during six years were evaluated, determining the most common type of disorder (inflammatory, infectious, proliferative). Epidemiological aspects such as species, breed, sex and age were taken into account. 270 reviews were evaluated and the prevalence was neoplasms (53%). The canine specie was the most observed, with 92% of cases. Females totaled 53%. The age ranged from one to 17 years and the interval of six to 10 years was most observed (40% of cases). The round cell neoplasms were the most prevalent, followed by breast neoformations.

Prevalence of neoplasia diagnosed in dogs at the veterinary hospital at eduardo mondlane university, mozambique

A retrospective study of tumors in dogs was carried out in the School Veterinary Hospital (HVE), Eduardo Mondlane University, Mozambique, between January 2004 and January 2009. Data from clinical-surgical records of tumor samples surgically removed, necropsy and cytological exams were used and sent for histopathology exams. During the study 210 tumors and about 27 different types of tumors were identified. Skin tumors (61.0%) were the most frequent, followed by mammary gland tumors (27.60%), reproductive system tumors (11.90%) and bone system tumors. The mammary gland tumors were observed only in females, with high prevalence in bitches which were not spayed or spayed after two years old. It was concluded that the neoplasia prevalence increase was correlated to the higher longevity of dogs, and breed also contributed for the development of determined tumors due to high incidence of mastocitomas in Boxer and German Shepherd breeds. The 100 % incidence of mammary gland neoplasia in females confirmed the higher predisposition for mammary gland neoplasia in females.

Stem anatomy and development of successive cambia in Hebanthe eriantha (Poir.) Pedersen: A neotropical climbing species of the Amaranthaceae

Hebanthe eriantha (Poir.) Pedersen, a climbing species of the Amaranthaceae increases in stem thickness by forming successive cambia. The family is dominated by herbaceous species and is constantly under discussion due to its disputed nature of the meristem. In the young stem small alternate segments of vascular cambium cease to divide and new arc of cambium initiates outside to it. The newly formed arcs connect with pre-existing alternate segments of cambium to complete the ring. On the contrary, in thick stems, instead of small segments, complete ring of cambium is replaced by new one. These new alternate segments/cambia originate from the parenchyma cells located outside to the phloem produced by previous cambium. Cambium is storied and exclusively composed of fusiform initials while ray cells remain absent at least in the early part of the secondary growth. However, large heterocellular rays are observed in 15-mm diameter stems but their frequency is much lower. In some of the rays, ray cells become meristematic and differentiate into radially arranged xylem and phloem elements. In fully grown plants, stems are composed of several successive rings of secondary xylem alternating with secondary phloem. Secondary xylem is diffuse-porous and composed of vessels, fibres, axial parenchyma while exceptionally large rays are observed only in the outermost regions of thick stems. Vessel diameter increases progressively from the centre towards the periphery of stems. Although the origin of successive cambia and composition of secondary xylem of H. eriantha remains similar to other herbaceous members of Amaranthaceae, the occurrence of relatively wider and thick-walled vessels and large rays in fully grown plants is characteristic to climbing habit. © 2013 Springer-Verlag Wien.

Morphology and anatomy of the diaspores and seedling of Paspalum (Poaceae, Poales)

RESUMO O conhecimento relativo ao diásporo e ao desenvolvimento pós-seminal de Paspalum L. é importante para a conservação da biodiversidade dos campos, devido sua importância na representatividade e no melhoramento genético de pastagens. A morfologia do diásporo e do desenvolvimento pós-seminal de Paspalum dilatatum Poir. (rizomatosa); P. mandiocanum Trin. var. subaequiglume Barreto (estolonífera), P. pumilum Nees. (cespitosa decumbente) e P. urvillei Steud. (cespitosa ereta) foi descrita procurando distinguir as espécies com diferentes formas de crescimento, e levantar características úteis para a taxonomia. P. dilatatum se diferencia por apresentar diásporo oval, de maior tamanho que as demais, com cinco nervuras salientes e tricomas; P. urvillei por apresentar diásporo com uma nervura central mais desenvolvida do que as duas nervuras laterais e tricomas; P. mandiocanum var. subaequiglume por apresentar diásporo com tricomas apenas na margem; e P. pumilum por apresentar diásporo glabro. A cariopse envolve a semente que apresenta embrião diferenciado, disposto lateralmente; apresenta hilo elíptico em todas as espécies estudadas e rostelo em P. dilatatum e P. mandiocanum var. subaequiglume. O desenvolvimento pós-seminal é semelhante nas quatro espécies e se inicia com a germinação, que é marcada pela emergência da coleorriza, seguida pelo coleóptilo. Essas características são comuns às demais Poaceae já estudadas, indicando um padrão para a família e não diferenciam as formas de crescimento.

Ultrassonografia transcraniana em cães hígidos: padronização da técnica e descrição anatômica

The study of the nervous system is increasing in Veterinary Medicine. Transcranial ultrasonography (TCUS) has the advantage of being a non-invasive and low cost method compared to computerized tomography (CT) and Magnetic Resonance Imaging (MRI). The temporal bone has been used as an acoustic window in TCUS in humans. This study aimed to correlate transcranial ultrasonographic images obtained through the temporal and occipital window with healthy dog's encephalic anatomy, and to standardize the technique. 37 adult mongrel dogs were used: 30 animals in vivo, in order to perform USTC screening and seven dog corpses for brain section as well as USTC planes. Data analysis was accomplished by the non parametric Wilcoxon test. Results obtained indicate that TCUS (in dorsal and oblique planes) is a viable method for brain evaluation in dogs weighting up to 10kg without anesthesia.
