Eremothecium ashbyii cultivated on "half cooked" cereal granules of rice, kaoliang, corn, millet, wheat bran, rice bran and bean refuse* is able to produce a considerable amount of riboflavin. It was found that the highest riboflavin production was obtained after 12-14 days' incubation at 28℃. The relative amount of riboflavin in these different granules was discovered in a decreasing order as follows: wheat bran, bean refuse, rice bran, millet, corn, kaoliang and rice. There is no difference in the amount of riboflavin synthesized by using different granular size of the same cereal.All these fermented products may be usect for enrichment of the riboflavin in processed-food and certain pharmaceutical preparations. Fermented wheat bran and bean refuse are considered to be most favourable for this purpose owing to this lower cost, simple operation and higher riboflavin content.*Bean refuse called Tou-Cha in Chinese is a by-product of bean curd.

Objective To investigate the effect of two kinds of drainage operation including incision and drainage of abdominal operation and percutaneous puncture and drainage operation under ultrasound guidance on the short-term curative effect, mortality and complications risk in patients with single giant bacterial liver abscess. Methods Eighty patients with single giant bacterial liver abscess were selected, and all patients were treated with conventional therapy. Among them, 40 patients underwent incision and drainage of abdominal operation (control group), and 40 patients underwent percutaneous puncture and drainage operation under ultrasound guidance (observation group). The short-term curative effect, operation time, time of returning to normal body temperature, time of returning to normal white blood cell, hospitalization time, mortality and incidence of postoperative complication were compared between 2 groups. Results There were no statistical differences in total effective rate and mortality between control group and observation group: 92.5%(37/40) vs. 97.5%(39/40) and 5.0%(2/40) vs. 7.5%(3/40), P>0.05. The operation time, time of returning to normal body temperature, time of returning to normal white blood cell and hospitalization time in observation group were significantly lower than those in control group:(44.52 ± 5.68) min vs. (98.59 ± 12.70) min, (3.25 ± 0.74) d vs. (4.86 ± 1.32) d, (5.20 ± 1.35) d vs. (7.42 ± 1.79) d, (16.94 ± 3.61) d vs. (25.52 ± 5.28) d. The incidence of postoperative complication was significantly lower than that in control group:10.0%(4/40) vs. 27.5%(11/40), and there were statistical differences (P<0.05). Conclusions Two kinds of drainage operation in the treatment in patients with single giant bacterial liver abscess possesses the same clinical efficacy for short-and long-term curative effect; but percutaneous puncture and drainage operation under ultrasound guidance application can efficiently alleviate the clinical symptoms and signs, accelerate the recovery process of disease and be helpful to reduce the risk of postoperative complications.

Objective To study signs of ultrasonography in multiple renal arteritis (MRA) by color Doppler flow imaging(CDFI) and X-ray angiography.Methods 2-D ultrasonography and color Doppler were performed on 23 cases of MRA with 39 diseased blood vessels.The morphology and diameters of stenonsed renal arteries of the kidneys were observed respectively by 2-D ultrasonography and CDFI.CDFI was adopted to observe maximum of velocity(Vmax),minimum of velocity(Vmin),resistance index(RI),acclerate(ACC) and acclerated time(TA) of the renal arteries,and the values were compared with those by X-ray angiography and with those of the normal controls.Results MRA's renal volume and diameter were significantly different from those of controls ( P

0 05). The forelimb functional tests demonstrated that, the number of food pellets eaten by PD rats with the contralateral side of 6 OHDA lesion (17 71?4 82) was significantly reduced compared with the controls (34 43?3 55)( P

Objective To determine whether pupil response to dilute tropicamide could be used as a diagnostic test for Alzheimer's disease (AD). Methods Pupil diameters of both eyes were measured simultaneously by an infra red automatic pupil diameter recorder and analyzer every 0 1 second for 30 minutes after instillation of 0 01% tropicamide to one eye and normal saline to the other. Three groups of patients were studied: 52 patients with AD, 33 with vascular dementia (VD), and 58 elderly controls. The percent change in pupil diameter of the treated eye was examined automatically by the analyzer. After finding the cut off point for differential diagnosis by receiver operator characteristic curve (ROC), its sensitivity, specificity and Kappa coefficient were calculated. Results Mean percent change in diameters of the treated eye showed a trend of fastest maximum dilation in AD group, and was significantly different from other groups at all the measurement time points after 10th minute instillation. The difference was most significant at the 18th minute after instillation, and 15% was used as a cut off point, the sensitivity was 0 81,specificity 0 79 0 82, and Kappa coefficient 0 62 0 67. Conclusions Pupil dilation test could be used as a screening method in the diagnosis of Alzheimer's disease, or as a tool for differential diagnosis between AD and VD.

Seventeen physiological,biochemicaland morphological indexes consistently showed that Astragalus polysaccharide was able to enhance the myocardia contractility,attenuate the area of myocardial infarction, and reduce the degree of myocardial damage of myocardially infarcted dog heart in vivo.The mechanism might be related to the inhibition of Na+-Kr+ATPase activity & the anti-free-radical-damage action.
