[Postoperative enteral feeding in digestive anastomosis with proximal oesophageal partner]. / Nutritia enterala postoperatorie în anastomozele digestive ce au ca partener proximal esofagul.

This paper aim is to discuss the advantages of enteral postoperative feeding on patients submitted to surgery finalized through an eso-digestive anastomosis; in these cases enteral feeding is often delayed 5-8 days after the surgery, and in case of an anastomotic dehiscence may be even impossible. Also, the paper promotes duodenostomy as an important enteral feeding way, and discusses the indications and contraindications of different enteral nutrition pathways in such cases. There were studied 230 cases, 149 cases submitted to cancer surgery and 81 cases with benign condition surgery followed by an eso-digestive anastomosis, in which the following enteral nutrition pathways was practiced: nasogastric or naso-esojejunal feeding tube (55 cases); Witzel jejunostomy (28 cases); gastrostomy (79 cases); duodenostomy (68 cases). Postoperative morbidity induced exclusively by the enteral nutrition pathway was encountered in 36% of patients. On patients with an eso-gastric cervical anastomosis or esogastric thoracic anastomosis we used jejunostomy as enteral feeding path and a gastric tube passed by pyloric canal for gastric decompression. In cases of esophageal reconstruction for benign esophageal strictures gastrostomy remains the best feeding method. Duodenostomy was practiced as a feeding pathway in cases of total gastrectomy with esojejunal anastomosis, with closure of the duodenal stump.

Biochemical and cytogenetical study of the mycoplasmal antigen and of the cyclophosphamide action in mammalians, in vivo. The action of some immunomodulatory antioxidants.

It was proved spectrophotometrically that Mycoplasma agalactiae antigen inoculated in vivo in sheep modifies the corresponding erythrocyte lysates reactivity toward methylene blue and neutral red and induces several types of chromosomal rearrangements. The treatment in vivo of sheep with an original preparation obtained from the Phaseolus vulgaris pods restores the erythrocyte lysates reactivity toward the two redox dyes and reduces the chromosomal abnormalities frequency induced by the mycoplasmal antigen. It was also demonstrated by optical and electronical microscopy that the Smise line mouse meiocytes exhibit chromosomal abnormalities induced by the cyclophosphamide treatment in vivo. In the case of concomitant treatment with the cyclophosphamide and C vitamin the same frequency of abnormalities was recorded as in the simple treatment with the drug.

[Purification of closterovirus type III associated with grapevine leafroll disease]. / Purification du clostérovirus du type III associé à l'enroulement de la vigne.

The closterovirus-like particles serotype III, associated with grapevine leafroll disease, were extracted from leaves by PEG precipitation and purified by differential centrifugation. The purification schedule steps were examined by enzyme linked immunosorbent assay (ELISA). The loss of virus during purification and the concentration of the preparations were estimated and the virus particles were visualised by electron microscopy.
