Comparison of different brown and white layer hybrid embryonic development and uptake of nutrients in the egg.

The objective of this study was to evaluate the comparison of different brown and white layers in embryonic development and uptake of nutrients in the egg. A total of 360 fertilized eggs obtained from two brown (Atak-S and Brown Nick) and two white (Atabey and Nick) layer breeders at 28 wk old. Hatching eggs from each genotype were examined on the day of setting for fresh egg analysis and then at the beginning of the embryonic day (E19) and embryonic day (E21) for egg, embryo and villus analysis. Differences in egg weight, shell percentages, relative weight of yolk and albumen, relative weight and length of embryo, villus height, some values of shell, yolk and albumen and relative chick weight in examined hybrids were significant. Yolk sac utilization of embryos during the incubation in the white layer hybrids was greater than that in the brown layer hybrids. Villus heights in the duodenum, jejenum and ileum of embryos in the brown layer hybrids was greater than that in the white layer hybrids. Genotype is important parameter to determine the egg composition at the same age and in animals being fed the same diet. It was observed that the consumption of yolk and shell nutrients from the embryos during the incubation was not related to whether embryos were from the brown or white layer hybrids. Only uptake of the yolk sac and villus height in the embryo among examined variables varied depending on whether the embryos were from the brown or white layer hybrids.

Differences in egg nutrient availability and embryo development in white layer breeder genotypes.

Because of consumers' preferences and also due to changes in production systems, the importance of pure breeds has increased again. There are a lot of differences among breeds which have been studied extensively, however, the differences during the incubation period are not yet fully known. Therefore, the present study was conducted to evaluate the composition of the egg parts, absorption of nutrients, and development of embryos from different genotypes. A total of 354 fresh hatching eggs were obtained from one hybrid (Lohman White, LW) and two pure breeds (Denizli and Gerze). Hatching eggs from each genotype were examined on the day of setting for egg analysis and then at the beginning of the embryonic d 19 (E19) and embryonic d 21 (E21) for egg, embryo, jejunum, and tibia analysis. On d 21 of incubation, the healthy chicks were removed and weighed. Egg weight, shell thickness, percentages of albumen, and some parameters of albumen composition (dry matter, water, ash, protein, energy, Na, Ca, K, and Mg) were higher in fresh eggs obtained from LW hens. Furthermore, the relative yolk sac and embryo weight, some yolk parameters (dry matter, water, protein, fat, and energy) and some shell parameters (dry matter, ash, Na, Ca, and K) were also higher in eggs obtained from LW hens during incubation. However, tibia deformation and villus width were lower in LW embryos than the other genotypes. Relative chick weights were 68.9, 72.0, and 68.0% in LW, Denizli, and Gerze genotypes, respectively. During incubation, differences in all examined parameters were significant except thickness and weight of shell, tibia deformation, and crypt depth. Yolk sac weight, some yolk composition parameters, K level in the shell, Cu level in the tibia, and villus height were also affected by genotype and period interaction. Based on these results, LW was found advantageous in terms of egg composition, however, regarding villus development and tibia deformation in embryos during incubation, pure breeds showed better results.

Granular cell tumor of the penis shaft: case report and literature review.

INTRODUCTION: Granular cell tumors (GCT) are uncommon soft tissue neoplasms of presumed neural origin that rarely involve the male external genitalia. Penile lesions are distinctly uncommon with less than 20 cases reported till now. OBJECTIVE: In the present paper we describe the clinicopathological and immunohistochemical findings in a case of GCT of the penis shaft in a 31-years-old man. RESULTS AND CONCLUSIONS: On physical examination the patient was found to have a small ovoid mass, 20 x 10 mm in diameter, at the left postero-lateral area of the penis' base. The mass was firm on palpation with no fixation on the neighboring tissues. The lesion was completely excised under loco-regional anesthesia. The surgical specimen was an ovoid, gray-white, elastic mass, of 10 x 5 mm. Microscopically, the tumor was moderately cellular and was composed of polygonal-shaped cells with abundant granular eosinophilic cytoplasm. Tumor cells were disposed in nests, cords, and trabeculae and showed perineural invasion. The tumor presented bland cytological features with only focal slight nucleo-megaly. Mitotic activity was undetectable. The tumor cells showed diffuse immunohistochemical expression for S100 protein. At 6 month after surgery the patient was free of persistent/recurrent disease or metastatic spread of the tumor. We discuss the clinical, histo-immunohistochemical and therapeutical features of this unusual penile tumor, the single one encountered in the Department of Pathology from Timisoara County Hospital and, to our knowledge, the only one reported in the Romanian medical literature.

[An unusual splenic tumor. Littoral cell angioma]. / O tumora splenica neobisnuita. Angiomul cu celule litorale.

Littoral cell angioma is a rare splenic tumor which develops from specialised endothelial cells of the splenic red pulp. Numerous papers published since 1991 when the tumor was firstly described till now were focused on the radiologic characteristics of the lesion. This paper presents the clinical, imaging and morpho-immunohistochemical features of a littoral cell angioma diagnosed in a 51 year - old woman, to our knowledge, the first documented case in the Romanian medical literature. The lesion might be suspected on the basis of the clinical and imaging signs, but the diagnosis of certitude is provided by the gross and microscopic examination supplemented with immunohistochemical methods.

[Pediatric psychiatry: evolution and developments]. / La psychiatrie infanto-juvénile evolution et développements.

Since 1986, the field of the child and adolescent clinics in the University Children Hospital Queen Fabiola is much developed. It is divided in five areas: the ambulatory sector, the medical psycho-psychiatry field, the day unit, the psychiatric hospitalisation and the ward. The population consists in babies (not yet born and born), children, adolescents. The clinical approach is multi and transdisciplinary including the child, his family and his life systems, caring staff included. Clinical research is centered on four axes: medical psychology, prevention, therapy and child psychiatry, somatic aspects included.

Histologic criteria for the diagnosis of gastric low-grade malt lymphoma.

Low-grade B cell lymphoma of the stomach have the features of mucosa-associated lymphoid tissue (MALT) and is characterised by lymphoid hyperplasia and infiltrations of lymphocytes into glandular epithelium or lymphoepithelial lesions. It may be difficult to distinguish low-grade lymphomas from benign inflammatory lymphoid infiltrates. Nine primary gastric lymphomas and 20 benign lymphoid hyperplasia were investigated for the type of tumour cells, lymphoepithelial lesions. Dutcher bodies, cytologic atypia, the density of lymphoid infiltrates, invasion of the muscularis mucosae, germinal centers, reactive epithelial atypia and acute inflammation. Our results suggest that B cells proliferation, lymphoepithelial lesions, cytologic atypia and Dutcher bodies are very important for the diagnosis of low-grade MALT lymphoma. None of these was seen in inflammatory infiltrates. The presence of germinal centers, acute inflammation and reactive epithelial atypia does not exclude a diagnosis of low-grade gastric lymphoma.

Intestinal metaplasia and dysplastic modifications in H. pylori gastritis.

Certain studies regarding modifications of gastric mucosa in the presence of infections produced by H. pylori add a new element in the pathology of gastric lesions with a high malignancy potential. From the certain premalignant lesions, a special place is occupied by intestinal metaplasia and by gastric dysplasia, because of their high frequency. This study is based upon the interpretation of 130 gastric biopsies in which the identification of H. pylori was pursued (by HE staining, Giemsa), o intestinal metaplasia and their types (by PAS-Blue Alcian ph 2.5 staining and High Iron Diamine-Blue Alcian ph 2.5) and the presence of neoplastic lesions. Particular aspects of our study are given by the association of H. pylori infection with certain types of intestinal metaplasia, with moderate or severe dysplastic lesions and with gastric carcinomas (especially the "intestinal" type).
