Abstract
Eryngium bornmuelleri Nab. (Tusî) is an endemic botanical from the Eastern Anatolia region of Turkey traditionally used for preparation of herbal tea. Within this study, phenolic composition, antioxidant capacities and inhibitory activities towards selected digestive enzymes of E. bornmuelleri leaf were investigated. Sequential extracts, obtained by extraction of plant tissue by ethanol, acetone and water exhibited pronounced antioxidant capacities and in a dose-dependent manner suppressed the metabolic syndrome related enzymes: α-amylase, α-glucosidase and pancreatic lipase. All extracts contained high levels of phenolic compounds. Flavonoid glycosides were the main phytochemicals detected, with rutin as the major compound (70% of total phenolics). Chlorogenic, hydroxybenzoic and caftaric acids as well as traces of caffeic, ferulic and rosmarinic acids were also detected. Correlation analysis indicated that phenolic compounds were the major sources of the enzyme-inhibitory activities. This study suggests that E. bornmuelleri leaf extracts can modulate the metabolism of sugars and fats through inhibition of the relevant digestive enzymes.

Abstract
In this study, previously developed five different state estimation methods are examined and compared for estimation of biomass concentrations at a production scale fed-batch bioprocess. These methods are i. estimation based on kinetic model of overflow metabolism; ii. estimation based on metabolic black-box model; iii. estimation based on observer; iv. estimation based on artificial neural network; v. estimation based on differential evaluation. Biomass concentrations are estimated from available measurements and compared with experimental data obtained from large scale fermentations. The advantages and disadvantages of the presented techniques are discussed with regard to accuracy, reproducibility, number of primary measurements required and adaptation to different working conditions. Among the various techniques, the metabolic black-box method seems to have advantages although the number of measurements required is more than that for the other methods. However, the required extra measurements are based on commonly employed instruments in an industrial environment. This method is used for developing a model based control of fed-batch yeast fermentations.

Abstract
Seeds of Zea mays L. were exposed to aflatoxine B1 (AFB1), aflatoxine G1 (AFG1) and selenium (Se) alone and in combination and allowed to germinate. Phytohormone levels of GA-like substances (GAs), trans-Zeatin (t-Z) and Indole-3-acetic acid (IAA) were determined by High Performance Liquid Chromatography (HPLC) when the roots of the germinating seeds reach 1.5-3.0 cm in length. The levels of endogenous hormones decreased in seeds treated with AFB1 and AFG1 compared to control; however an increase was noted in seeds exposed to AFG1 and Se together. AFB1 and Se treatment caused reduced hormone levels in most of the treatments. When plants were exposed to Se alone, the highest levels of GAs, t-Z and IAA were observed in the application of 800 ppm Se. The highest levels of GAs, t-Z and IAA were observed when seeds were treated with 0.2 ppm AFG1 + 8 ppm Se, 0.2 ppm AFG1 + 8 ppm Se and 0.2 ppm AFG1 + 0.08 ppm Se, respectively, whereas the lowest levels of the hormones were observed in 0.2 ppm AFB1 + 8 ppm Se, 0.2 ppm AFB1 + 0.08 ppm Se and 0.1 ppm AFB1, respectively. In conclusion, the levels of phytohormones were reduced by the treatment of AFB1 and AFG1 alone. However Se removed the negative effect of AFB1 on phytohormones, but not AFB1.

Abstract
The effects of environmental conditions on ammonia removal as struvite (Magnesium ammonium phosphate, MAP) were studied in a laboratory scale batch reactor. MAP precipitation was carried out by adding phosphoric acid and magnesium source either as MgCl, or MgO. The effect of temperature, pH, MgN:P ratios were studied. Temperature did not significantly affect ammonia removal between 25-40 degrees C and over 90% removal was obtained. The effect of pH, however,was significant and highest removal was reached at pH 8.5-9.0. The various stoichiometric ratios of ammonium to Mg and P have been tested and slight excess of Mg and P found to be beneficial for higher recovery of ammonia as struvite. However further increase in Mg and P ratios did not result in further ammonia removal which is also costly for the practical application of the process. When MgO was used as M source,the ammonia recovery was 60-70% whereas the useMgCl2 has increased this figure up to 95%. In addition a two step purification process was developed to recover MAP crystals from impurities of the anaerobic digester. Firstly, precipitates were dissolved in acid and impurities were removed by centrifugation. The clarified supernatant was re-precipitated by adjusting its pH with caustic. It was shown that in the two steps process white MAP crystals could be obtained with over 85% recovery to be used for another applications. The economical analysis of the process has shown that ammonia in the digester effluents can be recovered at the cost of $7.5-8.0 kg(-1) NH4+-N. The rate of reaction is very fast and is completed almost in minutes. This simplifies the process design resulting in a smaller reaction vessel.

Abstract
The objectives of this study were to investigate the effectiveness of oral megadose methylprednisolone (OMMP) therapy in children with chronic immune thrombocytopenic purpura (ITP). Twenty-two patients were given oral methylprednisolone daily for 7 d (30 mg/kg for 3 d and then 20 mg/kg for 4 d). OMMP therapy was repeated once per month if the platelet count was less than 20,000/mm3 at the 30th day of therapy, for up to six courses. The number of platelets of all patients increased gradually during the OMMP therapy, with a peak number at the 7th day, then decreased until the 14th day, and remained relatively stable until 12 months. During the study no patient had a platelet count less than 20,000/mm3 at the 3rd day and 50,000/mm3 at the 7th day. Although the number of platelets was gradually decreased between the 7th and 14th days, it remained above 100,000/mm3 for at least 12 months in the nine patients, and above 20,000/mm3 in the four patients. None of these 13 patients required hospitalization or therapy during the follow-up period. All of the patients tolerated the medication well. None of them reported side-effects that were severe enough to discontinue therapy. We conclude that OMMP therapy is a safe, easy and effective therapy in children with refractory chronic ITP, and it may provide long-term remission in about two thirds of the patients.

Abstract
PURPOSE To investigate the effect of propolis, a natural resin produced by honeybees, in the treatment of alkali-injured rabbit eyes. METHOD A corneal alkali burn was induced by applying filter paper immersed in 1 N NaOH on the central axis of the right corneas of 24 rabbits for 30 s. The animals were divided into three treatment groups: group 1 (control) was given 0.3% tobramycin and phosphate-buffered solution; group 2 was treated with antibiotic coverage and topical 1% ethanolic extract of propolis; group 3 received antibiotic coverage and topical 1% dexamethasone. The dexamethasone-treated group was maintained as the positive control. Drugs were instilled 4 times a day for 7 days. The corneal inflammation was evaluated by calculating the average inflammatory index obtained from clinical observation of the ciliary hyperemia, central and peripheral corneal edema at 24 h, 48 h, on day 5 and day 7, before sacrificing the animals. Then, the corneas underwent routine histological examination. RESULTS The effects of dexamethasone and propolis on healing of injured corneas were similar (p>0.05) and significantly better than controls at 24 h (p<0.01, p< 0.05, respectively), and on day 7 (p<0.05) with respect to the inflammatory index. On histological observation, inflammatory cell infiltration was lower as compared to control in both the dexamethasone and propolis groups (p<0.001) and similar with each other (p>0.05). CONCLUSIONS Our study shows that propolis has an anti-inflammatory effect comparable to dexamethasone in chemical corneal injury.

Abstract
Recently, there have been numerous reports on the use of cyclosporin A (CyA) in children with nephrotic syndrome (NS). In this prospective study, we wanted to evaluate the efficacy of CyA together with prednisone therapy in children with steroid-sensitive frequently relapsing NS. A total of 11 children (7 boys, 4 girls) with steroid-sensitive NS were included in this study. The patients ranged in age from 3.5 to 15 years (average 8.45 +/- 4.26 years). Renal biopsy showed minimal change disease in five, mesangial proliferation in four, focal glomerulosclerosis in one and membranous glomerulonephritis in one. The NS had lasted from 13 to 113 months (average 50.27 +/- 38.60 months). The number of relapses varied from three to 10 episodes with an average of 5.9 +/- 3.3 episodes. Patients received 5 mg/kg CyA daily in two divided doses for five months and prednisone for a total of eight weeks (30 mg/m2 daily for 4 weeks followed by 30 mg/m2 on alternate days for 4 weeks). After the completion of the treatment protocol, no therapy was given unless a relapse was observed. Mean follow-up period was 14.9 +/- 5.99 months with a range from six to 26 months. Before this combined treatment, there was a mean relapse rate of 0.144 +/- 0.05 relapses month with a range from 0.088 to 0.238. After discontinuation of therapy, the relapse rate dropped to a mean of 0.0179 +/- 0.031 with a range of 0 to 0.083. In conclusion, it would appear that a combination of CyA and prednisone is effective, sustaining the remission in steroid-sensitive NS. Corticosteroids in combination with CyA may be a better approach than conventional steroid treatment in such patients.

Abstract
Left ventricular filling patterns were assessed by Doppler echocardiography in 63 beta-thalassemia major patients, aged for to 21 years, with no clinical evidence of congestive heart failure and 63 age- and sex-matched normal controls. The patients with beta-thalassemia major were divided into three age groups, namely four to nine years (6.8 +/- 1.5 years), 10-15 years (12.1 +/- 1.6 years) and older than 15 years (17.3 +/- 1.7 years). They were compared with age- and sex-matched normal controls in respects of Doppler diastolic indices. The ratio between the early and late (atrial) peaks of flow velocity was higher and peak flow velocity in late diastole was significantly lower in patients with beta-thalassemia major as compared to controls in all three age groups (p < .001). As compared with the controls, peak early diastolic flow velocity was also significantly higher in the thalassemics aged 10 to 15 years (92 +/- 16 vs 80 +/- 12 cm/s, P < .01) and in those older than 15 years (95 +/- 16 vs 79 +/- 13 cm/s, p < .001). Restrictive left ventricular diastolic abnormalities were detected in a total of 34 (54%) patients with beta-thalassemia major, whereas left ventricular systolic abnormalities were identified only eight (13%) of them. None of the patients without left ventricular diastolic abnormalities showed left ventricular systolic abnormalities. There was not any significant correlation between the hematologic parameters, such as mean serum ferritin, maximum serum ferritin and the number of blood units transfused, and left ventricular Doppler diastolic indices (p > .05). From the data presented here, we therefore conclude that left ventricular diastolic abnormalities develop in patients with beta-thalassemia major in the early phase of the disease and before the appearance of systolic abnormalities, when clinical symptoms of congestive heart failure are absent.

A comparison of different filters for white cell reduction. Turk J Pediatr 1998; 40:89-95. [PMID: 9673534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/08/2023]
Abstract
Removal of white blood cells (WBCs) from blood components before transfusion by filters with at least 3 log10 depletion may prevent or delay leukocyte-associated transfusion reactions such as HLA alloimmunization, non-hemolytic febrile reactions, transmitted infections (e.g., CMV, HTLV-1), and immunomodulation. The aim of this study was to compare the leukocyte removal efficiency (LRE) of six commercial bedside filters that are said to achieve 3 log10 (Bio R-01), Leucostop 4LT-1, Pall RC 50) and 4 log10 (Bio R-01 Plus, Pall RC 400, Pall RC XL-1) WBC depletion. A total of 430 units of whole blood ranging from 32 to 92 for each filter type were analyzed by an automated counter before and after filtration. Postfiltration blood samples were also evaluated for WBCs by Nageotte chamber. All the filters demonstrated leukocyte removal about 1 log10 less than the manufacturer's claim. The fourth generation filters showed a better performance than the third generation filters. Of them, Pall RC XL-1 showed the best efficacy with 99.93 percent leukocyte removal and a median residual WBCs of 1.6 x 10(6) per unit. These results indicate that the fourth generation filters, which are designed for the filtration of packed red cells, in particular Pall RC XL-1, are also able to reduce WBCs from whole blood below the critical antigenic leukocyte load (5 x 10(6)), and can be efficiently used for polytransfused patients to prevent alloimmunization.

Abstract
A study was undertaken to investigate bone regeneration in guinea pig mandibles implanted with Pyrost in comparison with artificial bone defects as controls. Bone defects were prepared in the angles of mandibles of 30 guinea pigs. The findings demonstrated that this bone substitute material stimulated bone healing, i.e. bone regeneration, in comparison with empty control cavities. Bone regeneration and new bone formation were found to be more extensive in Pyrost-implanted areas than in controls.

Abstract
Dens in dente (dens invaginatus, tooth within a tooth, dilated composite odontome) is an abnormal tooth form which occurs most frequently in the permanent maxillary lateral incisor region. Dens in dente may occur, however, in any tooth in the dental arch, although these other forms are comparatively rare. It may appear within both the coronal part of the tooth and the root, although coronal forms are more common. In this paper, a case of extreme dens in dente with pulpal involvement at an early stage of eruption is presented.

A new surgical approach has been used in a case of genital lymphedema. After resection of the lymphedematous mass, U-shaped flaps were made from the suprapubic region anteriorly and the posterior scrotal skin posteriorly. The denuded penis was transposed to its original place by passing it through a buttonhole incision made on the anterior flap. The testicles were placed and fixed in pouches prepared between the anterior and posterior flaps. The patient had an acceptable postoperative outcome both in testicular function and habitual sexual activities.
