Is combined therapy more effective than growth hormone or hyperbaric oxygen alone in the healing of left ischemic and non-ischemic colonic anastomoses?

OBJECTIVE: Our aim was to investigate the effects of growth hormone (GH), hyperbaric oxygen and combined therapy on normal and ischemic colonic anastomoses in rats. METHODS: Eighty male Wistar rats were divided into eight groups (n = 10). In the first four groups, non-ischemic colonic anastomosis was performed, whereas in the remaining four groups, ischemic colonic anastomosis was performed. In groups 5, 6, 7, and 8, colonic ischemia was established by ligating 2 cm of the mesocolon on either side of the anastomosis. The control groups (1 and 5) received no treatment. Hyperbaric oxygen therapy was initiated immediately after surgery and continued for 4 days in groups 3 and 4. Groups 2 and 6 received recombinant human growth hormone, whereas groups 4 and 8 received GH and hyperbaric oxygen treatment. Relaparotomy was performed on postoperative day 4, and a perianastomotic colon segment 2 cm in length was excised for the detection of biochemical and mechanical parameters of anastomotic healing and histopathological evaluation. RESULTS: Combined treatment with hyperbaric oxygen and GH increased the mean bursting pressure values in all of the groups, and a statistically significant increase was noted in the ischemic groups compared to the controls (

Registration of a Laser Beam Scattered from an Aerosol Located in the Probe Beam Aperture

An experimental setup has been developed that allows recording the flux of probing radiation scattered from dispersed particles in the 0° direction. To suppress the beam passing through the swarm of dispersed particles a reference beam was used. The reference beam was formed from the probe beam and aligned in the registration plane with the beam passing through the swarm of particles. The Michelson interferometer was tested in an experimental setup to determine the sizes of dust particles of heterogeneous systems. It was shown that by placing a heterogeneous system in one of the arms of the interferometer, it was possible to register the scattered radiation at the angle 0°. This facilitates calculation of the sizes of particles with the same accuracy over the entire size range. To verify the method the iron powder particles sized 50-63 [mu]m were used

Pendrin expression in nodular and non-nodular thyroid tissues

Introduction: Different mechanisms for the expression of pendrin which is an apical iodide transporter have been reported in nodular thyroid tissues compared to normal thyroid. The aim of the present study was to determine the alterations of pendrin expression in nodular and surrounding non-nodular thyroid tissues and clarify the role of pendrin in the functional behaviour of nodular lesions. Material and methods: Twenty-six nodular and paired non-nodular normal thyroid tissues were collected at the same centre. Patients were divided into two groups based on the function of the dominant thyroid nodule; hot nodules (n = 18) and cold nodules (n = 8). mRNA levels of pendrin were evaluated by quantitative RT-PCR. Pendrin protein expression was determined by immunohistochemical analysis. Results of dominant nodules were compared to non-nodular thyroid tissue of the same patient. Results: No statistically significant difference was found with respect to qualitative and quantitative measurements of pendrin expression between hot and cold nodules. However, percent immunohistochemical staining of pendrin was significantly higher in both hot and cold nodules compared to non-nodular thyroid tissue of the same patients. RT-PCR revealed comparable mRNA levels of pendrin gene between hot nodules and corresponding normal thyroid tissues. However, in cold nodules, significantly decreased mRNA levels of pendrin were observed compared to normal thyroid tissue. mRNA levels of pendrin showed significant positive correlation with TSH in corresponding non-nodular thyroid tissues. Conclusions: The present study demonstrates that expression of pendrin could not be influenced by TSH in thyroid nodules and expression level of pendrin seems not to have an effect on nodule function.

Celem badania było ustalenie zmian w ekspresji pendryny w guzkowej tkance tarczycowej i otaczającej ją pozaguzkowej tkance tarczycowej, aby wyjaśnić rolę pendryny w zachowaniu czynnościowym zmian guzkowych. Materiał i metody: W tym samym ośrodku pobrano 26 wycinków guzkowej tkanki tarczycowej i sparowanych wycinków pozaguzkowej prawidłowej tkanki tarczycowej. Pacjentów podzielono na dwie grupy w zależności od statusu czynnościowego guzka dominującego: grupę z guzkami gorącymi (n = 18) i grupę z guzkami zimnymi (n = 8). Poziom mRNA i pendryny oznaczono ilościowo metodą RT-PCR. Ekspresję białka pendryny oznaczono metodą immunohistochemiczną. Wyniki dla guzków dominujących porównano z wynikami dla tkanki pozaguzkowej u tego samego pacjenta. Wyniki: Nie stwierdzono statystycznie znamiennych różnic pomiędzy guzkami gorącymi i zimnymi, jeżeli chodzi o wyniki oznaczenia ilościowego i jakościowego ekspresji pendryny. Procentowe barwienie immunohistochemiczne w kierunku pendryny było natomiast znamiennie większe zarówno w przypadku guzków gorących, jak i zimnych w porównaniu z tkanką pozaguzkową u tych samych pacjentów. RT-PCR wykazało porównywalne poziomy mRNA genu kodującego pendrynę w guzkach gorących i prawidłowej tkance tarczycowej u tych samych pacjentów. Z kolei w przypadku guzków zimnych stwierdzono znamiennie niższe poziomy pendryny w porównaniu z prawidłową tkanką tarczycową. Stwierdzono też korelację dodatnią poziomu mRNA pendryny i poziomu TSH w korespondujących tkankach pozaguzkowych. Wnioski: W przeprowadzonym badaniu wykazano, że na ekspresję pendryny nie może mieć wpływu TSH w guzkach tarczycy oraz że poziom ekspresji pendryny nie wydaje się wpływać na czynność guzków.

Proceedings of the West African Hybrid Sorghum and Pearl Millet Seed Workshop

Sorghum and pearl millet are the most important cereal crops in West Africa where they provide 70% of total cereal production that provide the major complements in the diets of people in the region. Research progress in the improvement of sorghum and millet is, therefore, of vital importance to the well being of people in West Africa. The Hybrid Sorghum and Pearl Millet Seed Workshop in West Africa is the culmination of the research and development effort by the Institut National de Recherches Agronomiques du Niger (INRAN) , the International Sorghum and Millet Collaborative Research Support Program (INTSORMIL), and the International Crop Research Institute for the Semi-arid Tropics (lCRISAT) during the last 10 years. The workshop served as a forum for documenting experience gained in the development, release, and diffusion of NAD-l as the first commercial sorghum hybrid in Niger. It marked a significant milestone in the history of agriculture for Niger and possibly for West Africa. The workshop brought together sorghum scientists from throughout Africa, the United States, India, and Europe. Mr. B.R. Barwale, the 1998 recipient of the World Food Prize who is credited for laying the foundation of the seed industry in India also attended the meeting and shared his experience with a paper entitled Hybrid Seed Experiences in Developing Countries
