Abstract

A simple technique of microgel electrophoresis of single cells (DNA Comet Assay) was used to detect DNA comets in irradiated quail meat samples. Obtained DNA comets were evaluated by both photomicrographic and image analysis.Quail meat samples were exposed to radiation doses of 0.52, 1.05, 1.45, 2.00, 2.92 and 4.00 kGy in gamma cell (Gammacell 60 Co, dose rate 1.31 kGy/h) covering the permissible limits for enzymatic decay and stored at 2 o C. The cells isolated from muscle (chest, thorax) in cold PBS were analysed using the DNA comet assay on 1, 2, 3, 4, 7, 8 and 11 day post irradiation. The cells were lysed between 2, 5 and 9 min in 2.5% SDS and electrophroesis was carried out at a voltage of 2 V/cm for 2 min. After propidium iodide staining, the slides were evaluated through a fluorescent microscope. In all irradiated samples, fragmented DNA stretched towards the anode and damaged cells appeared as a comet. All measurement data were analyzed using BS 200 ProP with software image analysis (BS 200 ProP, BAB Imaging System, Ankara, Turkey). The density of DNA in the tails increased with increasing radiation dose. However, in non-irradiated samples, the large molecules of DNA remained relatively intact and there was only minor or no migration of DNA; the cells were round or had very short tails only. The values of tail DNA %, tail length and tail moment were significantly different and identical between 0.9 and 4.0 kGy dose exposure, and also among storage times on day 1, 4 and 8. In conclusion, DNA Comet Assay EN 13784 standard method may be used for not only screening method for detection of irradiated quail meat depending on storage time and condition but also for the quantification of applied dose if it is combined with image analysis.Image analysis may provide a powerful tool for the evaluation of head and tail of comet intensity related with applied doses.

ÖZET: İlaçlama ünitelerinin uygulama performanslarını belirlemek için çeşitli kalitatif ve kantitatif yöntemler geliştirilmiştir. Uygulamalarda hata varyansını azaltmak için çok sayıda örneğin analizi yapıldığından, ölçüm yöntemlerinin pratik, kolay ve ekonomik olması arzu edilir. Kalitatif yöntemlerde ölçümler, görüntü işleme programlarıyla yapılmaktadır (Bs200Pro, BAB Ltd. Şti., TR). Bu yöntemde örnekleme materyali olarak suya duyarlı, yağa duyarlı kartlar ve kromekote kartları kullanılmakta ve neme duyarlı olduklarından uygun olmayan şartlarda renk değiştirerek görüntü işleme kaliteleri bozulmaktadır. Kantitatif yöntemlerde ise filtre kağıdı, petri kabı ve bitki yaprağı gibi örnekleme materyalleri kullanılmakta ve uygulamalarda püskürtme sıvısına pestisit yerine gıda boyası karıştırılmaktadır. Bu yöntemde yüzeyden yıkanan maddenin bozulmadan tamamen çözücüye karışması, kullanılan örnekleme materyalinin özelliğine bağlıdır. Ayrıca uygulamadan sonra yüzeyde tutunan madde, açık havada solar radyasyona maruz kaldığından bozulabilmekte ve çözeltinin konsantrasyonu değişebilmektedir. Bu çalışmada kalitatif ve kantitatif analiz yöntemlerinde görüntü işleme kalitesini, renk maddelerinin bozulmasını ve renk maddelerinin geri kazanımını etkileyen faktörler literatür bilgileri ışığında derlenmiştir.

INVESTIGATION OF QUALITATIVE AND QUANTITATIVE ANALYSIS METHODS IN EVALUATING
SPRAY APPLICATION PERFORMANCE

ABSTRACT: Various qualitative and quantitative methods were developed for the determination of spray application performance. These methods are desired to be practical, easy and economic because of analyzing lots of samples to decrease error variance. The measurements in quantitative methods were made with image processing software. Water-sensitive, oil-sensitive and kromekote cards are used as sampling materials and their image processing quality is spoiled by changing color at the unsuitable conditions because of their sensitivity to humidity. Sampling materials such a filter paper, petri dishes and plant leaf are used in quantitative methods and food dye is mixed to spray liquid instead of pesticide in the spray application. At this method, the mixing of dye completely washed from surface without degradation, depends on the properties of the used sampling material. On the other hand, dye deposited on the surface after the application may be degraded due to its explosion to solar radiation at the open atmosphere and this can change the concentration of solution. In this study, the factors affecting the recovery of color dyes, degradation of dye materials and image processing quality in qualitative and quantitative methods were reviewed regarding up to date literatures.

Abstract:
We tested the hypothesis that 5 cm H2O of positive end-expiratory pressure (PEEP) reduces the incidence of pneumocephalus in patients who undergo spinal intradural tumor surgery. Fifty-three ASA I to III patients who underwent thoracolumbar intradural tumor surgery between the years 2003 and 2006 were included in this study. All patients received propofol, fentanyl, and cisatracurium for induction of the anesthesia. Maintenance was provided by propofol infusion and, oxygen (50%) and air (50%). Group I (n=28) did not receive PEEP whereas group II (n=25) received PEEP as 5 cm H2O. Cranial computerized tomography was taken at 8 hours after the surgery and cases were evaluated for pneumocephalus using BAB Bs200ProP Image System software. Pneumocephalus areas between 0.03 and 4.24 cm2 were observed in 9 patients, 8 in group I and 1 patient in group II at the 8th postoperative hour, at various localizations. There were no neurologic findings in other patients except for 2 patients in group I who presented with headache and mental status change. Although the cerebrospinal fluid leakage is minimal, N2O is not used and the patients are well hydrated, pneumocephalus with neurologic deficits may occur in patients undergoing microsurgical spinal intradural tumor surgery in prone position. In our study, we showed that using 5 cm H2O PEEP perioperatively reduced the risk of pneumocephalus. However, more cases must be studied to support this hypothesis.

Abstract
Abstract: We aimed to evaluate the structural and functional changes in the thymus and kidneys of rat pups whose mothers were given cyclosporine A (CsA) during lactational period. Six adult nursing Wistar rats and their 30 pups were studied. Rat pups were divided into four groups as follows: 21-day treated group and 21-day placebo group, each including 10 breastfeeding pups sacrificed on the 21st day, whose mothers were given CsA or placebo, respectively (infancy groups) and, 60-day treated group and 60-day placebo group, each including five breastfeeding pups sacrificed on the 60th day, whose mothers were given CsA or placebo, respectively (puberty groups). While CsA levels of mother rats were very high, CsA levels of 21-day treated group pups were zero. There were no renal histomorphometric differences between study and control pups in both age groups. Renal function parameters showed significant differences between study and control pups in the infancy group: the 21-day treated group pups had significantly lower urine volume, proteinuria, FENa and urinary NAG/creatinine ratio. GFR was also lower in the 21-day treated group, but the difference was not significant, and serum creatinine levels were also not different. Renal function differences were not present among the pubertal pups. Thymic corticomedullary ratio of the 21-day treated group was significantly higher than the 21-day placebo group, while there was no difference between the 60-day treated group and 60-day placebo group. There were no significant changes in the number and distribution of CD3+, CD4+, and CD8+ thymocytes between study and control pups in both age groups. In conclusion, breastfeeding by CsA-treated mother rats induced structural alterations in the thymus and functional changes in the kidneys of the rat pups during infancy. Disturbances in the kidneys and thymus mostly improved after CsA exposure was over

In this study, the genotoxicity of the artificial sweeteners acesulfame potassium, aspartame, saccharin,
and sorbitol, which are used in food industry and by patients with diabetes, was investigated in human
peripheral lymphocyte cells using the single-cell gel electrophoresis (comet) technique. Human
lymphocyte cells were treated with the substances for three hour at each of the three dosages (1.25, 2.5,
and 5 ppm). The chemical additives were studied, and the related DNA damages in the study group were
compared to the control group for each of the treatment dosages. The DNA breakages observed in the
comet assay were assessed in terms of tail moment and tail DNA percent using the comet parameters.
The statistical and photographic analyses were performed using SPSS 15 and BAB BS 200 Pro
software, respectively. Based on the results for the short-term in vitro treatments, the 4 different food
flavorings were found to have genotoxic effects.
