Six citrate phosphate dextrose (CPD)-saline adenine glucose mannitol (SAG M) quadruple systems were evaluated for the preparation and storage of leukocyte-poor platelet concentrates (PC) from buffy coats. The platelet storage bags examined were manufactured from normal polyvinylchloride (PVC) or special-type plastics. Biotest supplied PVC 76 (n = 14) and PVC 763 (n = 16) NPBI supplied PSV 3277 (n = 15) and DPL-110 (n = 14) and Terumo supplied Teruflex (n = 18) and molded Teruflex (n = 14). The PC were stored for 7 days at 22 degrees C on a horizontally shaking platform. Cell counts, pH, PO2, PCO2, morphology score and swirling patterns were monitored at 5, 72, 120 and 168 h. The plasma volumes averaged 63 ml and ranged from 39 to 81 ml, the overall mean +/- SD platelet concentration was 0.89 +/- 0.33 X 10(9)/ml. None of the PC had a leukoyte count higher than 10 X 10(6) per unit. After storage for 168 h, the pH ranged from 6.56 to 7.40 for all brands. The PO2 remained stable and even rose significantly (p less than 0.05) during storage in the NPBI PSV 3277 and Terumo molded Teruflex bags. The PCO2 decreased equally in all bags. Morphology scores were well maintained in 98% of all PC for up to 120 h, and in 83% at 168 h. A swirling pattern score of 2.5 or greater predicted with a specificity of 100% a good morphology score in the PC.(ABSTRACT TRUNCATED AT 250 WORDS)

The production of thermolabile (LT) enterotoxin was compared in a defined medium reported by Staples et al. (SAG medium) for the production of thermostable (ST) enterotoxin and the Casamino acids-Yeast extract (CAYE) medium. Aliquots were drawn frum cultures of an enterotoxigenic (LT+, ST+) E. coli in both media at different times, growth curves were plotted, and culture filtrates tested for toxin activity. Levels of LT and ST and in the SAG showed that it is as suitable as CAYE for the production of LT. The addition of either glucose (1%) or lincomycin (90 microgram/ml) to SAG medium increased LT levels, but no synergistic effort could be observed if both substances were added concomitantly. Cultures in SAG medium incubated stationarily for 72 h at 37 degrees C yielded more LT than shaking cultures incubated similarly.

Objective: To investigate the effect of acupuncture on Parkinson's disease (PD) patients with tremor and its potential neuromechanism by functional magnetic resonance imaging (fMRI). Methods: Forty-one PD patients with tremor were randomly assigned to true acupuncture group (TAG, n = 14), sham acupuncture group (SAG, n = 14) and waiting group (WG, n = 13). All patients received levodopa for 12 weeks. Patients in TAG were acupunctured on DU20, GB20, and the Chorea-Tremor Controlled Zone, and patients in SAG accepted sham acupuncture, while patients in WG received no acupuncture treatment until 12 weeks after the course was ended. The UPDRS II and III subscales, and fMRI scans of the patients' brains were obtained before and after the treatment course. UPDRS II and III scores were analyzed by SPSS, while the degree centrality (DC), regional homogeneity (ReHo) and amplitude low-frequency fluctuation (ALFF) were determined by REST. Results: Acupuncture improved the UPDRS II and III scores in PD patients with tremor without placebo effect, only in tremor score. Acupuncture had specific effects on the cerebrocerebellar pathways as shown by the decreased DC and ReHo and increased ALFF values, and nonspecific effects on the spinocerebellar pathways as shown by the increased ReHo and ALFF values (P < 0.05, AlphaSim corrected). Increased ReHo values were observed within the thalamus and motor cortex of the PD patients (P < 0.05, AlphaSim corrected). In addition, the default mode network (DMN), visual areas and insula were activated by the acupuncture with increased DC, ReHo and/or ALFF, while the prefrontal cortex (PFC) presented a significant decrease in ReHo and ALFF values after acupuncture (P < 0.05, AlphaSim corrected). Conclusions: The cerebellum, thalamus and motor cortex, which are connected to the cerebello-thalamo-cortical (CTC) circuit, were modulated by the acupuncture stimulation to alleviate the PD tremor. The regulation of neural activity within the cognitive brain regions (the DMN, visual areas, insula and PFC) together with CTC circuit may contributes to enhancing movement and improving patients' daily life activities.
