Composition chimique et indice de palatabilité des feuilles de Adenodolichos rhomboideus Leucaena leucocephala et Stylosanthes guianensis chez la chèvre locale à Lubumbashi

Cette expérience a été menée pour évaluer la composition chimique et l'appétence de A. rhomboideus, légumineuse moins connues qui peut avoir le potentiel d'être incluse dans l’alimentation des ruminants en saison sèche comme supplément de foin de faible qualité. La palatabilité du fourrage d’Adenodolichos rhomboideus (O. Hoffm) Harms a été testée en comparaison de celui de Leucaena leucocephala et de Stylosanthes guianensis. Un foin de graminées (Imperata cylindrica et Setaria palude-fusca) a été utilisé comme fourrage de référence. Cette étude a été menée selon la méthode dite « cafétéria » dont l’indice de palatabilité a été estimé en fonction de fourrage de foin selon la formule P = (Ti/Di)/ (T1/D1). Ti et Di sont les quantités de foin consommées et distribuées respectivement. T1 et D1 sont les quantités de légumineuses consommées et distribuées. Les teneurs moyennes en protéines brutes ont été de 100, 132 et 270g/kg MS respectivement pour Stylosanthes, Adenodolichos et Leucaena. Suivant l’indice de palatabilité, le fourrage de Leucaena a été le plus consommé. Les indices de palatabilité des fourrages de Stylosanthes et d’Adenodolichos ont été statistiquement semblables (p<0,05).  Adenodolichos rhomboideus présente une faible palatabilité, mais il contient des teneurs en protéines brutes supérieures à la limite  recommandée pour l’entretien des ruminants (80 g/kg MS) et supérieures à celle de S. guianensis.Mots clés : Caprins, appétibilité, légumineuses, saison sèche, Congo (RD), Adenodolichos rhomboideus

Six years survival on imatinib with no disease progression after diagnosis of metastatic duodenal gastrointestinal stromal tumour: a case report

Introduction: A duodenal Gastrointestinal Stromal Tumour (GIST) is a rare finding and until recently advanced disease had a poor prognosis. A PubMed search revealed no reports of more than five years survival of inoperable GIST on chemotherapy with WHO performance status zero. Case Presentation: A 68 year old female was diagnosed with unresectable GIST in the duodenum with metastasis to liver, pancreas and omentum in November 2001. She was commenced on imatinib mesylate (Glivec) chemotherapy. This case report was prepared from the medical records and radiology reports. She had good tolerance with stable disease. After six years her CT scan showed no disease progression and her WHO performance status was zero. Conclusion: This report supports the view that imatinib is a safe and effective drug in controlling disease progression in advanced metastatic GIST and plays an important role in improving the patient's quality of life

Influence de facteurs environnementaux influençant la teneur en urée dans le lait de vache en Wallonie et estimation des rejets azotés

Study on environmental factors influencing the urea content of cow's milk in Wallonia and estimation of nitrogen rejection. In Wallonia (South of Belgium), the urea content of milk produced on farms is assessed by the "Comité du lait". A total of 8,295,337 pieces of data recording the urea content in milk tanks was collected on Walloon farms in 2000 and during the period 2002-2011. These data were analyzed using a linear model. The fixed effects of the agricultural area or vulnerable zone, the month, the year and the interactions between these parameters were included in the model. The levels of fat and protein content in the milk were used as covariates. The average urea content in milk was found to be 255 mg·l-1. Four percent of the observations recorded a urea content of over 350 mg·l-1 and 14% recorded a urea content of over 400 mg·l-1. The models explained 38% and 35% of the variation in milk urea for the agricultural area and the vulnerable area variables, respectively. Within these models, the variables of month, region, year and the month-year interaction were the components that provided the most information. Milk urea content was higher in the summer period – April to October – than during the winter period – November to March – (287 vs 210 mg·l-1). This observation can be explained by the change in the cows' diet. During the summer, most of the cows grazed; ingestion of grass can lead to a nitrogen surplus in the diet. In the so-called "Limoneuse" and "Sablo-limoneuse" agricultural areas, recorded urea content was lower than in "Ardenne" and "Haute-Ardenne" (223 and 220 mg vs 278 and 284 mg·l-1, respectively). This difference can be explained by a greater use of grass in the diet in Ardenne and Haute-Ardenne. In vulnerable areas, urea content was lower (236 vs 273 mg·l-1). Annual nitrogen production calculated using different prediction equations ranged from 82 to 119 kg N per cow depending on the agricultural area

L'effet de l'extrait végétal de Yucca Schidigera sur l'excrétion oocystale chez le poulet de chair

In Algeria, coccidiosis constitutes one of the main constraints which hinder the development of the poultry production and is responsible for major losses to the poultry industry, reducing performance and increasing production costs, especially an increase of mortality and misuse of antibiotics. These molecules have fatal effects on the animal and public health, thus, alternatives were introduced, in particular the extracts of plants. The present study, conducted in October 2013, was carried out in five hundred broiler chicks (Hubbard F15 strain). The chicks were monitored from birth to the 52nd day. These animals, with homogeneous weight of 93 g and mixed sexes, came from the same hatchery and underwent the same environmental conditions. Animals of the first lot, identified as “Control lot” received a food exempt from any additive but antibiotics added to water. The animals of the second lot, identified as “Experimental lot”, received a water exempt from any additive and the same food added with the Yucca Schidigera extract. The objective of this study was the evaluation of the oocystale excretion by Mac Master’s method to estimate the activity of the Yucca Schidigera extract. The results highlighted an increase of oocystale excretion until 82.250 oocysts.g-1 of feces in the control lot and 22.950 oocysts.g-1 of feces in the experimental lot. The average levels of oocysts were significantly lower during three weeks from J14 to J35 in the experimental lot, then remained comparable for the rest of the experiment period (J36 to J51). These results showed that this additive considerably reduced the coccidian eggs elimination and proved its efficiency in the coccidiosis control. Keywords: Yucca Schidigera, Coccidiosis, Broilers, Antibiotics.En Algérie, la coccidiose constitue l’une des principales contraintes qui entrave le développement de la production avicole et cause d’énormes pertes économiques, en l’occurrence l’augmentation du taux de mortalité et l’usage abusif des antibiotiques. Ces derniers ont des effets néfastes sur la santé humaine et animale. Ainsi, des alternatives ont vu le jour, en particulier l’utilisation des extraits de plantes. La présente étude, mise en place en octobre 2013, a été menée dans un élevage comportant cinq cent poussins d’un jour appartenant à la souche de type chair Hubbard F15. Les poussins ont été suivis de leur naissance jusqu’au 52ème jour. Ces animaux, d’un poids homogène de 93 g et de sexes mélangés, provenaient du même couvoir et ont subi les mêmes conditions d’ambiance. Les animaux du premier lot, identifié comme «Lot témoin», recevaient un aliment exempt de tout additif mais une eau additionnée d’antibiotiques. Les animaux du deuxième lot, identifié comme «Lot expérimental», recevaient une eau de boisson exempte de tout additif et un même aliment additionné de l’extrait de Yucca Schidigera. L’objectif de cette étude a été l’évaluation de l’excrétion oocystale, par la méthode de Mac Master, pour déterminer l’activité de l’extrait de Yucca Schidigera. Les résultats ont révélé une augmentation d’excrétion oocystale jusqu’à 82.250 oocystes.g-1 de matières fécales pour le lot témoin et 22.950 oocystes.g-1 de matières fécales pour le lot expérimental. Les nombres moyens d’oocystes ont été significativement plus bas durant 3 semaines allant de J14 à J35 dans le lot expérimental, puis devenaient comparables le reste du temps de J36 à J51. Ces résultats montrent que cet additif a considérablement réduit l’élimination des œufs de coccidies et prouvé son efficacité dans la maîtrise de la coccidiose.

Perivascular epithelioid cell tumor of the retroperitoneum in a young woman resulting in an abdominal chyloma

Perivascular epithelioid cell tumor (PEComa) is an extremely rare neoplasm which appears to have predominancy for young, frequently Asian, women. The neoplasm is composed chiefly of HMB-45-positive epithelioid cells with clear to granular cytoplasm and usually showing a perivascular distribution. These tumors have been reported in various organs under a variety of designations. Malignant PEComas exist but are very rare. The difficulty in determining optimal therapy, owing to the sparse literature available, led us to present this case. We report a retroperitoneal PEComa discovered during emergency surgery for abdominal pain in a 28-year-old Asian woman. The postoperative period was complicated by chylous ascites that was initially controlled by a wait-and-see policy with total parenteral nutrition. However, the chyle production gradually increased to more than 4 l per day. The development of a bacterial peritonitis resulted in cessation of production of abdominal fluid permitting normal nutrition without chylous leakage. Effective treatment for this rare complication of PEComa is not yet known; therefore, we have chosen to engage in long-term clinical follow-up

A rare myoepithelioma of the sinonasal cavity: case report

Myoepithelioma is a rare benign neoplasm. Pure accounting for less than 1% of all salivary gland tumors. Only three cases of sinonasal myoepithelioma have been reported in the literature. Diagnosis of myoepithelioma through light microscopy is possible and immunohistochemistry is done to facilitate the diagnosis. The lesion is so rare that there are no specific indications/guidelines for its treatment. We report to you a rare case of sinonasal myoepithelioma in a 57 year old Asian female
