    Notes: Summary A case of fourth ventricle cysticercosis treated with praziquantel is presented. The disappearance of the lesion six months after the treatment was demonstrated by CT scan. A review of the literature indicates that this is a very exceptional result, because with recently intraventricular cysticercosis was considered to be non-responsive to praziquantel treatment, making surgery necessary.

    Notes: The role of CD4+ T lymphocytes in the resistance of BALB/c mice to Trypanosoma cruzi was examined by in vivo depletion using monoclonal anti-CD4 antibodies (MoAbs)〈. When the administration of MoAbs was initiated 2 days before, or 5 to 12 days after the infeetion (dpi) with 50 bloodstream-from trypomastigotes of the Tulahun strain, mice showed an enhanced susceptibility to the parasite. Speeific IgM. but not IgM responses, were inhibited in anti-CD4-treated and infected miceHowever, when anti-CD4 treatment of mice was delayed until the 8th week of infection. neither a reactivation of the infection as determined by mortality or parasitaemia. nor a modulation of the titre of anti- T. cruzi IgG antibodies was detected. Furthermore, mice chronically infeeted with T. cruzi and deprived of CD4 or T cells resisted the challenge with 50,000 trypomastigotes (approximately 1000 LD50)Secondary antibody responses against parasite antigens were inhibited after in vitro depletion of CD4+ cells in chronically infected mice before boosting with T. cruzi antigens. However, recipients of CD4 or T-cell-depleled spleen cells from mice chronieally infected with T. cruzi were protected when challenged with the parasiteThe possibility that the parasite control is maintained by long-lived B cells capable of rapid differentiation into IgG-secreting plasma cells in the absence of T helper cells is discussed considering the present data

    Notes: Abstract Solitary hamartomatous duodenal polyps are a clinical entity considered until now to express an incomplete or initial form of Peutz-Jeghers syndrome (PJ syndrome). Following our experience of 1 case, we analyzed the clinical characteristics of the 12 previously reported cases of solitary hamartomatous duodenal polyps. In none of these cases did we find any documentation of mucocutaneous pigmentation, a family or personal history of intestinal polyps, or local neoplasic degeneration of the disease, and all cases presented during the fifth or sixth decade of life. Thus, we conclude that solitary hamartomatous duodenal polyps constitute a different entity to PJ syndrome, the most appropriate elective treatment for which is endoscopic electrosurgical polypectomy.

    Notes: Abstract Fourier transform algorithms are described using tensor (Kronecker) products and an associated class of permutations. Algebraic properties of tensor products and the related permutations are used to derive variants of the Cooley-Tukey fast Fourier transform algorithm. These algorithms can be implemented by translating tensor products and permutations to programming constructs. An implementation can be matched to a specific computer architecture by selecting the appropriate variant. This methodology is carried out for the Cray X-MP and the AT&T DSP32.

    Notes: Abstract The efficiency of different nitrogenous fertilizers under forced leaching conditions was determined in pot experiments using ryegrass as an indicator plant in a sandy loam soil. Treatments were: ON (unfertilized), AN (ammonium nitrate), U (urea), DAP (diammonium phosphate), T (Triabon), FK (Floranid Komplett) and CDU (crotonylidendiurea). N source effects on N uptake, and N leached (as % of N applied) were evaluated. Results show that the fertilizers which behaved best with regard to N uptake were FK followed by Triabon and AN. The most soluble fertilizers, AN and urea, gave the highest N leaching losses. Significant correlations between EUF-NI (rapidly soluble fraction) and leaching, as well as between EUF-N (I + II) and N uptake by the plant (where EUF-N II relates to the slowly soluble fraction) were obtained.

    Notes: Abstract A rapid and sensitive method has been developed for the determination of lead in water samples by flame atomic absorption spectrometry using on-line preconcentration on a microcolumn packed with silica gel treated with a mixture of Aliquat 336 and nitroso-R-salt. The lead is retained at pH 5.5. The preconcentrated lead is directly eluted from the column to the nebulizer-burner system using 150 μL of 0.1 mol/L hydrochloric acid. The optimum preconcentration conditions are given and the retention efficiency achieved is higher than 80%. The enrichment factor is 37 and 100 for sample volumes of 5 and 30 mL, respectively. The limits of detection are 10.0, 6.0 and 4.0 ng/mL when 5, 10 and 30 mL of water is preconcentrated.
