Experimental transmission of a sarcosporidian from Alpine ibex to domestic sheep and goats.

Sporocysts of Sarcocystis sp. from dogs fed with ibex meat were orally inoculated into kids and lambs. Three kids, given 4 x 10(6) and 4 x 10(4) sporocysts, respectively, died from acute sarcocystosis. Schizonts, though found in all the tissues of these kids, were particularly numerous in the kidneys, brain and spinal cord. Another three kids inoculated with 5 x 10(3) sporocysts and two lambs, inoculated with 1 x 10(6) and 5 x 10(3) sporocysts, respectively, showed no clinical signs and were sacrificed between 111 and 130 days after infection. Mature sarcocysts were found both in the heart and striated muscles of these animals. No parasitic stage was found in two kids and two lambs used as uninoculated controls. Biological differences between Sarcocystis sp. from ibex and the other sarcosporidians with a canine-caprine or canine-ovine cycle are stressed.

Cytochemical assay of glucose-6-phosphate dehydrogenase in koilocytes.

New cervical smears were obtained from 24 patients with a cytologic diagnosis of typical condyloma for a cytochemical assay of glucose-6-phosphate dehydrogenase (G6PDH) activity in the koilocytes that are pathognomonic of this lesion. The smears were air dried and were processed according to Nachlas' modified technique. The controls used were smears from normal cases (which show no G6PDH activity), from dysplasias (which show high levels) and from carcinomas (which show very high G6PDH levels). In the cases of typical condyloma studied, the level of G6PDH was null in 16 (66.7%), very low in 2 (8.3%) and low in 6 (25.0%). If this assay for G6PDH gives the total enzymatic activity of the cell, showing low enzymatic levels in condylomas and high enzymatic levels in dysplasias and carcinomas, an increase in G6PDH activity could indicate the transition of an intraepithelial lesion from condyloma to cervical intraepithelial neoplasia.

[Echotomography-computerized tomography integration in the tissue characterization of renal angiomyolipoma].

A sonographic and a computed tomographic study of 29 patients was performed in order to assess the possibilities of these imaging techniques in tissue characterization of renal angiomyolipoma. From the review of the results the authors, confirming the very high accuracy of the two associated methods for a correct diagnosis, underline the possibility to identify the hamartoma mesenchymal components with the possibility of more prognostic and therapeutic informations.

Auditory evoked potentials (AEPs), early (BAEPs) and long latency components (LLCs) in Parkinson's disease: a 12 month follow-up study.

In 14 untreated informed patients (5 M, 9 F, mean age 62 yrs) with initial idiopathic Parkinson's disease AEPs, early (BAEPs) and long latency components (LLCs) were studied. In 10 subjects experimental session were carried out before treatment (L-Dopa plus Carbidopa, 0.25-0.50 g/die) and at 2, 6 and 12 months intervals. At the same time all patients underwent clinical assessment by Webster Rating Scale evaluation. BAEPs. The IPLs prolonged (greater than 2.5 SD) in 6 patients: in 3 the III-V, in 2 the I-V and in 1 the I-III. The absolute latencies were abnormally prolonged in 11 subjects: V wave in 4, III wave in 3, II wave in 2 and I wave in 3. The absence of one or more components were observed in 12 out of 14 patients, the most frequently absent was the II wave (12 patients). LLCs. The absolute latencies of P1 and N1 waves were prolonged respectively in 4 and in 3 subjects. The P1-N1 IPL was prolonged only in one patient. A follow-up study demonstrated transitory improvement of the AEPs previously observed abnormalities. The improvement was partially in agreement with clinical assessment.
