Transplante pancreato-duodenal em ratos com microcirurgia. A téchnica e os resultados após 12 anos de experimentação

In this study we present the technical details, adaptations and modifications of the original procedure of pancreaticoduodenal transplantation in rats described by Lee et al. in 1972. We also present the results and technical failures observed in a follow-up of 12 years. From March, 1982 to December, 1994, we performed in the Laboratory of Surgical Technique and Experimental Surgery of Faculty of Medicine, Botucatu - UNESP, Brazil, 665 duodenopancreatectomies in donor rats and 592 surgeries for revascularization of the pancreatic graft in recipient animals. The observed percentage of technical failures in donor rats was 11% due to bleeding and/or vascular complications, irregular flushing of the graft with saline and respiratory insufficiency. In recipients of grafts, we observed a percentage of technical failures of 22,5% due to porto-caval thrombosis, vascular bleeding, pancreatitis and graft ischemia. In both surgeries, the successful results are directly related to the technical performance of the surgeon and the cares in the postoperative period.

Morphologic characterization and evaluation of the productivity of nine rootstocks of rose bush (rosa spp.)

In Brazil, garden and cut rose bushes are propagated through cuttings or grafting. The rootstocks used in most of the traditional areas of cultivation are not identified, being known just by the vulgar name. There is not any information in the literature on the morphologic characteristics, nor about the productivity of different cultivars on the rootstocks available in Brazil. The objective of this work was to characterize and determine productivity of nine rootstocks (Rosa multiflora 'Paulista'; R. multiflora 'Japones'; R. multiflora 'Iowa'; R. multiflora 'Kopmans'; R. indica 'Mayor'; R. indica x multiflora; R. sp. 'Natual Brier'; R. manetti and R. canina 'Inermis') grafted with 'Versilia' and 'Tineke' scions. Morphologic studies were undertaken to characterize branches of adult plants to determine shape and dimensions of the leaf; number of prickles/15 cm of stem; vigor of the stems; incidence of Diplocarpon rosae (blackspot) and coloration of the leaf. The productivity (number of commercial flowers/plant/month) was evaluated for 6 months (October, 2000 to March, 2001), in the city of Andradas, Minas Gerais State, located at 1251 meters above sea level. Since there was significant difference in just two months for both rootstocks, 'Tineke' and 'Versilia', no rootstocks could be considered inadequate. Nonetheless, in general, the rootstocks that showed a better performance with 'Tineke' were, R. multiflora 'Kopmans' and R. manetti and with 'Versilia', R. multiflora 'Kopmans' and Rosa sp. 'Natual Brier'.

Cryptosporidiosis of the biliary tract mimicking pancreatic cancer in an AIDS patient

Diarrhea caused by Cryptosporidium sp is frequent in patients with AIDS, but involvement of other organs of the digestive tract is uncommon. We report a case of Cryptosporidium-associated obstruction of the biliary tract mimicking cancer of the head of the pancreas in a 43-year-old woman with AIDS.

Resistance of rose rootstocks to Meloidogyne hapla nematode

Roses are widely used in landscaping. One of the most important fitossanitary problems of this ornamental plant in gardens is the fitonematodes, especially Meloidogyne hapla, which is the most important one in colder climate regions. This work had the objective of study the resistance of nine rose rootstocks (Rosa multiflora 'Paulista', R. multiflora 'Japanese', R. multiflora 'Iowa', R. multiflora 'Kopman's', R. indica × multiflora, R. indica 'Mayor', R. sp. 'Natual Brier', R. manetti and R. canina 'Inermis') to Meloidogyne hapla nematode. Ten replications of each rootstock were used. The roots, collected in a commercial area of cut roses, visually had galls there were isolated and identified. The inoculum of M. hapla was previously produced in rose and tomatoes seedlings under greenhouse conditions. The plants were harvested ninety days after inoculation. The roots were washed and the number of eggs and juveniles recuperated in the root system of each plant was estimated by the Final Population (FP), and the Reproductive Factor (RF) was calculated. The rootstocks with RF<1 values were considered resistant, and the ones with RF>1, susceptible. Rosa manetti and Rosa sp. 'Natual Brier' rootstocks showed the lowest values for RF, indicating that, although they are susceptible, they provide the lowest nematode reproduction. Based on the RF values, it was concluded that all the rose rootstocks evaluated were susceptible to M. hapla nematode.
