Background Mammalian bite injuries create a public health problem because of their frequency, potential severity, and increasing number. Some researchers have performed fragmentary analyses of bite wounds caused by certain mammalian species. However, little practical information is available concerning serious mammalian bite wounds that require hospitalization and intensive wound management. Therefore, the purpose of this study was to perform a general review of serious mammalian bite wounds. Methods We performed a retrospective review of the medical charts of 68 patients who were referred to our plastic surgery department for the treatment of bite wounds between January 2003 and October 2012. The cases were analyzed according to the species, patient demographics, environmental factors, injury characteristics, and clinical course. Results Among the 68 cases of mammalian bite injury, 58 (85%) were caused by dogs, 8 by humans, and 2 by cats. Most of those bitten by a human and both of those bitten by cats were male. Only one-third of all the patients were children or adolescents. The most frequent site of injury was the face, with 40 cases, followed by the hand, with 16 cases. Of the 68 patients, 7 were treated with secondary intention healing. Sixty-one patients underwent delayed procedures, including delayed direct closure, skin graft, composite graft, and local flap. Conclusions Based on overall findings from our review of the 68 cases of mammalian bites, we suggest practical guidelines for the management of mammalian bite injuries, which could be useful in the treatment of serious mammalian bite wounds.

Purpose: A cost effective tool for the clinical measurement of trunk reposition sense is clearly needed. This study was to analyze intrarater and interrater Reliability of trunk repositioning error (TRE) test which assesses trunk position sense using a portable digital inclinometer. Methods: Twenty four normal healthy subjects were recruited. TRE was measured using a portable digital inclinometer. A digital inclinometer (Acumar-ACU360; Lafayetter Instrument) with precision to $1^{\circ}$ was placed on skin over the spinous process from first to second thoracic vertebra (T1-T2) and secured with double-sided tape. TRE test during sitting forward and lateral flexion movement was assessed. When they reached a point approximately 50% of full trunk flexion range, the examiner instructed the subjects to stop and told them. This was the target position that they should try to reproduce exactly. Each subject performed six trials. Results: ICC (2,1) for intrarater reliability (with-day and between-day) of TRE test in sagittal and frontal plane of movement was 0.75 and 0.78 (excellent reliability). Interrater reliability was 0.66 in sagittal and 0.64, frontal plane (fair to good reliability). However, there were poor correlations between an average of TRE test in sagittal and frontal plane. Conclusion: TRE test using a portable digital inclinometer demonstrated good to excellent reliability. The device may be a cost effective clinical measurement for trunk reposition sense measurement.

Presently, the world population of the elderly is growing. By improving health hygiene and welfare indicators, mortality and birth rates decrease and life expectancy increases, making the present century the century of elderly. Aging is one of the main risk factors for development of cancer, which itself is the second cause of death in old people. This study was conducted to assess the prevalence of cancer in the elderly covered by the Islamic Republic of Iran Broadcasting (IRIB) insurance program and to obtain suitable programs for cancer screening and early detection, increase patient survival, improve elderly care and to reclaim the cost of treatment in comparison to the national and international statistics. This is a cross-sectional study conducted on all elderly patients diagnosed with malignancy based on their pathology reports. In this study, of the total 75,500 patients covered by IRIB insurance, 17.2% belonged to the elderly group, males accounting for 53.3%. The most common cancers in old men were prostatic cancer (61.3%), colon cancer (10.3%) cancer of the hematologic system, bladder cancer (9.6%), lung cancer (9.1%), thyroid cancer (3.9%) and brain tumors (1.3%). In the elderly women, the most common cancers were breast cancer (80.1%), colon cancer (5.1%), thyroid cancers (4.4%), bladder and hematologic system malignancies (3.6), lung cancer (2.9%) and brain tumors (0.7%). In addition, the prevalence of cancer was almost the same as national and international statistics. With the exception of non-melanoma skin cancer no difference was shown in prevalence of cancer between IRIB elderly patients and the other groups of cancer patients in Iran.

Heart condition should be observed for long periods of time because it does not appear abnormal all the time. However, there are many difficulties checking our health for a long time due to its size, operation of equipment, and cost. To solve these problems, an electrocardiograms(ECG), specially interfacing three gel-less metal electrodes for low cost portable applications, is designed and implemented. Gel-less metal electrodes are used for ECG monitoring system instead of gel-type electrodes that can cause skin rashes and itching problem. The whole ECG system consists of two parts-analog and digital circuits. The analog measurement circuit that has a 18*25mm size is made up of op-amps maintaining a sufficiently high common-mode noise rejection and passive elements of SMD type. Analog heart signal is converted to digital stream suitable for display on a TFT-LCD by an 8-bit microcontroller. The size of the completed ECG system is 25*80*50mm and its weighing is about 150g, which is small enough to be easily used. Therefore, the implemented ECG system can be used as a portable one.

Background: Atopic dermatitis one of the most common chronic skin diseases, is caused by various environmental and genetic factors. Methods: A total of 2609 healthy newborns who were enrolled in the COCOA study (COCOA) from 2008 to 2015 were surveyed for indoor environmental exposure to fungi during gestation and then diagnosed postnatally for atopic dermatitis. The fungi collected during the gestation of 20 normal subjects and 20 infants that developed atopic dermatitis were identified using Illumina's MiSeq platform and analyzed for their diversity and species. Results: A total of 2,609 respondents were surveyed (52.8% male and 47.2% female) Children, 1, 2, and 3 years old diagnosed with atopic dermatitis comprised 15.2%, 15.7%, and 14.1% of the respondents, respectively. The prevalence of exposure to mold during gestation was 1.46 (95% CI, 1.05-2.04) and 1.52 (95% CI, 0.95-2.43), in the first and third years after birth, respectively. One-year-old children with atopic dermatitis and no fungal markers detected in the bathroom environment during gestation accounted for less than 5% (aOR, 1.51; 95%CI, 0.96-2.38) and in the group less than 5 ~ 30% (aOR, 2.21; 95%CI, 1.00-4.89), 3-year-old children had an increased prevalence of atopic dermatitis of more than 30% (aOR, 9.48, 95%CI 1.42-63.13). Conclusions: Exposure to indoor fungi during gestation and infancy is associated with the development of atopic dermatitis in children. The phyla and genera of the fungi in the indoor house dust differed during gestation. This suggests that exposure to indoor fungi during gestation may be associated with the development of atopic dermatitis in children. Future research will be necessary to establish the underlying mechanisms.

This study was constructed the correlations of the embryonic developmental rates and the frequency of chromosome aberration using ear-skin-fibroblast cell in nuclear transfer (NT) derived embryos. Karyoplast-oocyte complexes were fused and activated simultaneously, then cultured for seven days to assess development. The developmental rates of NT and in vitro fertilization (IVF) embryos were 55.4% vs 63.5%, 31.7% vs 33% and 13.4% vs 16.8% in 2 cell, 8 cell and blastocyst, respectively. Firstly, the frequency of chromosome aberrations were evaluated using fluorescent in situ hybridization (FISH) technique with porcine chromosome 1 submetacentric specific probe. Chromosome aberration was detected at day 3 on the embryo culture, the percentages of chromosomal aneuploidy in NT and IVF embryos at 4-cell stage were 40%, 31.3%, respectively. Secondly, embryonic fragmentation was evaluated at 4-cell stage embryo. Frequency of embryonic fragmentations was in 51.3% of NT, 61.3% of IVF, 28.9% of parthenogenetic activation at 4-cell stage. The proportion of fragmentation in NT embryos was higher than activation embryos. This result indicates that chromosomal abnormalities and embryonic fragments are associated with low developmental rate in porcine NT embryo. It is also suggest that abnormal porcine embryos produced by NT related with lower implantation rate, increased abortion rate and production of abnormal fetuses.

Purpose: The purpose of this study was to examine the relationship between pigmental reaction and blood components, such as white blood cell (WBC), lymphocyte, monocyte, red blood cell (RBC), hemoglobin, mean corpuscular index (mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC)), hematocrit, platelet and neutrophil segment, after Cupping Glass Therapy (CGT). Subjects: Twenty-five healthy adults participated in this study; Methods: Subjects had undergone CGT for 5 days and were divided into two groups (dark color (DCG) and light color (LCG)) depending the level of pigmental reaction. Blood was collected from each subject at the beginning of this study and recollected after 5 day s'CGT. Results: The percentage of lymphocytes was higher in LCG than in DCG after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01), The number of RBC was more in DCG than in LCG both before (p<.01) and after CGT (p<.05). The amount of hemoglobin was more in DCG than in LCG both before (p<.01) and after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01). Mean corpuscular index showed that both MCH (p<.05) and MCHC (p<.01) were higher in DCG than in LCG after CGT, but only MCHC before CGT (p<.01). It also showed either decreased MCV (p<.01) or increased MCHC in LCD after CGT (p<.01). Hematocrite was higher in DCG than in LCG both before (p<.01) and after CGT (p<.01). The percentage of neutrophil segments was higher in BCG than In LCG after CGT (p<.01) and was significantly decreased in LCD after CGT (p<.05). However, neither the number of WBC and platelets nor the percentage of monocytes was significantly different between DCG and LCG either before or after CGT. Conclusion: Pigmental reaction was significantly related to the changes of blood conponents after CGT. The results of this study suggest that CGT may have an effect on the components of blood cells.

In order to evaluate the exposure to the radiologic technologists from patients who had been administrated with radiopharmaceuticals, we measured the spatial dose rates at $5{\sim}300\;cm$ from skin surface of patients using an proportional digital surveymeter, 1.5(PET scan) and 4hr(bone scan) after injection. In results, the exposure to the technologists in each procedure was small, compared with the dose limits of the medical workers. However, the dose-response relationships in cancer and hereditary effects, referred to as the stochastic effects, have been assumed linear and no threshold models ; therefore, the exposure should be minimized. For this purpose, the measurements of spatial dose rate distributions were thought to be useful.

Dermal fibroblasts produce the many components of the extracellular matrix (ECM) that are needed to maintain connective tissue integrity and repair tissue injuries. This study investigated the effects of Areca catechu extract (ACE) on dermal fibroblast cell activation. Cultured human dermal fibroblasts were treated with ACE, and then ECM production was determined by ELISA, Western blot and RT-PCR. ACE significantly accelerated the production of type 1 collagen, fibronectin, and transforming growth factor (TGF)-${\beta}1$ by ELISA and type 1 collagen by Western blot assay. ACE also increased the gene expression of COL1A1, TGF-${\beta}1$, keratinocyte growth factor (KGF) and insulin growth factor (IGF)-1. These results suggest that ACE has the potential to stimulate ECM production and that it might be suitable for maintaining skin texture.

The ability of many toxigenic fungi to invade and develop in a wide variety of raw ingredients of human diet renders human exposure to mycotoxing very difficult to avoid. Most of the energy-rich commodities, such as cereal grains, oil seeds, tree nuts, and dehydrated fruits, are susceptible to mycotoxin contamination. Mycotoxins therefare have been recognized as an important class of hazardous substances in the human food chain. Although human exposure to mycotoxins is largely through ingestion, inhalation and skin contact may also be significant under conditions other than consumption of foods. Human ingestion of mycotoxins is due to consumption of contaminated dietary ingredients and the edible tissues and products of domestic animals that have been exposed to mycotoxins in moldy feed. Large scale acute human mycotoxicoses, such as ergotism in France, alimentary toxic aleukia in Russia, yellow rice syndrome in Japan, endemic nephropathy in Balkan countries, and acute aflatoxin poisonings in India and Taiwan, have been well documented, indicating that mycotoxicosis is a global problem. In some incidents, hundreds of victims were killed and many more became seriously ill. The mycotoxins that have been implicated in the etiology of these human diseases include aflatoxins, citreoviridin, cyclopiazonic acid, ergot alkaloids, moniliformin, ochratoxin A, trichothecenes, tenuazonic acid, and zearalenone. Among these, aflatoxins have been also implicated in the etiology of human primary liver cancer in those high-incidence countries in Africa and southeast Asia. It is well recognized that cause-effect relationship between mycotoxins and human diseases is very difficult to establish, especially for the cancer connection. Careful risk assessment must be performed to determine whether a mycotoxin indeed warrants costly regulatory actions.
