METHODSThe hemostatic abilities of the two methods were analyzed retrospectively in all six gastric endoscopic submucosal dissection cases. The treated vessel diameter, compressed vessel frequency, and bleeding frequency after cutting the vessels were noted by the recorded videos. The coagulation mechanism of the two power settings was evaluated using the data recording program and histological examination on macro- and microscopic levels in the ex vivo experiments using porcine tissues. RESULTSF1-10 method showed a significantly better hemostatic ability for vessels ≥ 2 mm in diameter and a trend of overall better coagulation effect, evaluated by the bleeding rate after cutting the vessels. F1-10 method could sustain electrical current longer and effectively coagulate the tissue wider and deeper than the S method in the porcine model. CONCLUSIONF1-10 method is suggested to achieve a stronger hemostatic effect than the S method in clinical procedures and ex vivo models.展开更多

Recently, the ICNIRP （International Commission on Non-Ionizing Radiation Protection） has published new exposure guidelines with regard to these fields. The aim of this paper is to demonstrate the calculation of the currents and electric fields induced in the human body by external electric fields at 60 Hz, using numerical human models of anatomically-realistic human bodies, and to compare those results with the basic restrictions proposed by the new guidelines. As a result, in the case that a human is exposed to an electric field of 1 kV/m at 60 Hz the short-circuit current of 18 μA flows though the ankles. Furthermore, the electric field of 40 mV/m in the nervous tissue of the adult model is induced by exposure to external electric fields at the reference level, which is enough smaller than the basic restrictions established in the ICNIRP guidelines for occupational exposure.展开更多

It is a reasonable fact to be understood, that the exposure to such explicit content of obscenity is acceptable in Western culture but somehow or rather, the acceptance of obscenity among the Asian society is still taboo and this has geared parents to pay greater attention to what type of media content should be watched by their children. The researcher believes the audience could also educate themselves by watching such television series since Malaysia is lacking in sexual education. This research consists of qualitative content analysis. The researcher had included the obscene visuals and dialogues in order to justify the existence of such sexual portrayal on the Grey＇s Anatomy TV series. A theory was selected for this study--the application on selected variables from a previous research done by the Henry J. Kaiser Family Foundation （Sex on TV4, 2005）. The researchers had found that such TV content could be a medium to promote safe sex messages since Malaysia lacks in sex education. The implication on theory was to distinguish the obscenity portrayal in TV series in shaping the audiences＇ acceptance.展开更多

Methods： Twenty-four healthy male New Zealand rabbits were randomly divided into a normal group, a model group, an EA group and a medication group, 6 rabbits in each group. Experimental dry eye syndrome models were prepared in rabbits by using 0.1% benzalkonium chloride for eye drops. Tear secretion volume, break-up time of tear film （BUT） and corneal fluorescein staining score were observed before and after the treatment. Periodic acid Schiff （PAS） staining method was used to observe the changes of conjunctival goblet cells in rabbits. After hematoxylin eosin （HE） staining, morphological changes of rabbit cornea, conjunctiva and lacrimal gland tissues were observed under light microscope. Results： Compared with the normal group, tear secretion volume and BUT were significantly reduced （both P^0.01）, while the corneal fluorescein staining score was significantly increased （P〈O.01） in the model group. Compared with the model group, tear secretion volume and BUT were significantly increased, while the corneal fluorescein staining score was significantly decreased in the EA group and the medication group （all P〈0.01）. Compared with the normal group, the number of conjunctival goblet cells in the model group was significantly reduced; compared with the model group, the numbers of conjunctival goblet cells were all relatively higher in the EA group and the medication group. Pathological lesions of cornea, conjunctiva and lacrimal glands all showed improvement by HE staining in the EA group and the medication group after the intervention. Conclusion： EA can improve tear secretion and tear film stability of rabbit dry eye syndrome, and repair the pathologic lesions of conjunctival goblet cells, corneal epithelia, cornea, conjunctiva and lacrimal glands.展开更多
