Determination of Staphylococcus aureus on Radiographic Cassettes Used in Chest X-Ray Examination in Selected Hospitals in Cagayan de Oro City

Volt Wilmer Q. Meneses — 2014-01-31

Radiography plays a very important role in medical diagnosis but the equipment and accessories used bear a considerable risk of harboring nosocomial bacteria which may complicate a patientâ€™s original condition. The study aimed to determine the presence or absence of Staphylococcus aureus commonly found on x-ray equipment specifically sizes 14x17â€ or 14x14â€ used for a patient. Swab samples were collected from selected x-ray equipment before and after examination. The swabbing procedure was carried out using sterile Eveponâ„¢ swab sticks. The selected surfaces were first swabbed before being cleaned with chemical disinfectant of appropriate dilution by the hospitals. The second swabs were done after being contacted by patientâ€™s surfaces. A total of 36 radiographic imaging cassettes were then taken to the DOST Region X microbiology laboratory for culturing and enumeration using standard laboratory procedure. The result shows the absence of MRSA (Methicillin-resistant Staphylococcus aureus) in the swabbed radiographic imaging cassettes. Radiologic departments of both hospitals were compliant of implementing the standard protocol of aseptic technique as observed among the swabbed radiographic cassettes

Determination of Staphylococcus aureus on Radiographic Cassettes Used in the Intensive Care Unit on Selected Hospitals

Francis John A. Casabuena — 2014-01-31

Staphylococcus aureus which were found to be a gram positive; facultative anaerobe, is a bacterium that is a member of firmicutes and is frequently found in the human respiratory tract and on the skin although S.aureus is not always capable of causing disease, Staphylococcus aureus can cause infections and example of this infection is the skin infections. The study assessed the determination of Staphylococcus aureus on radiographic cassettes used during x-ray procedure in intensive care unit at selected hospitals in Cagayan de Oro City. The objectives of the study were to determine the presence or absence of Staphylococcus aureus on radiographic cassettes used during radiographic examination in intensive care unit and determine if the selected hospital were practicing the asepsis method in their institution. The researchers used experimental design that focused only on Staphylococcus aureus bacteria on radiographic cassettes employed in the intensive care unit before and after the x-ray was done on selected hospitals in Cagayan de Oro City. The results revealed that no presence of Staphylococcus aureus on the radiographic cassettes used before and after the radiographic procedure in intensive care unit. However, the hospitalâ€™s understudy must not be complacent for there are many patients in health care system that has different kinds of disease and every individual is a host to an enormous number of microbes and there is no exception. Moreover, it is the hospitalâ€™s responsibility to prevent nosocomial infection.

Effect of Pomegranate and Mixed Fruit Juice in Radiation Exposed Female Webster White Mice (Mus musculus) Linn.

Yvonne Karla G. Martinez — 2014-01-31

Too much exposure to x-ray radiation causes side effects that contribute to behavioral change. The researchers conducted a study on pomegranate, grapes, and apples which are fruits high in polyphenols and anti-oxidants. The study is about the effect of pomegranate and mixed fruit juice supplementation for two weeks on female Webster white mice (Mus musculus) Linn prior to irradiation and evaluation. Sixteen mice were divided into four groups (control, supplement with radiation exposure, no supplement with exposure group, and supplement with no exposure group) and all groups were exposed to a specified water maze test after irradiation of radiation groups and eighteen hours after the first water maze test. A histopathological study was then conducted to assess the hepatoprotective effect of the supplement. The results of the water maze test indicate a constant performance in the mice based on the objectives with a faint evidence of memory and spatial learning enhancement. Histopathologies found in the mice were fewer in pomegranate groups which show alleviation of liver condition as compared to no supplementation groups. Researchers recommend assessing the amount and administration of the supplement, controlling the environment and pre-screening to ensure no external factors affect mice behavior and health.

Effects of Food Irradiated with X-rays on White Websterâ€™s Mice (Mus musculus) Linn.

Alfonso L. Ortega III — 2014-01-31

Irradiating food is a common procedure today to preserve its quality and reduce spoilage. The popularity of this method inspired the researchers to conduct an experiment on irradiated food and its effects to human consumption. The researchers have done this experiment to discover its effects on living creatures. The experiment will try to answer the basic question if there is really a negative effect of food irradiation. The experiment involves white mice, pellets as food exposed to radiation with the help of an x-ray machine. The irradiated pellet was feed to a number of white mice for 30 days continuously. The results of experiment have identified some negative effects on white mice with the use of pellets irradiated with high intensity x-rays. The subject white mice suffer from weight loss, decrease on appetite on the last week of the experiment. One of the treated white mice died also on the last week of the experiment. There were inflammatory cells found on the hepatic tissue which indicated as hemorrhage and necrosis. The result will help and contribute on the readers to know more knowledge about food irradiation and its negative effects.

Effects of X-ray Radiation on Physical Appearance and Large Intestines of Swiss Webster Mice (Mus musculus) Linn.

Rochelle B. Acut — 2014-01-31

This study was conducted to identify the effects of X-ray radiation on Swiss Webster mice (Mus musculus). It focused on four major points: (1) Determine the changes in body weight; (2) Determine the presence of hair loss; (3) Determine the presence of erythema; (4) Examine histological changes in the large intestine of Swiss Webster mice (Mus musculus). In answering these four statements, the researchers used the experimental design. The method was further used in determining the effects of x-ray radiation on Swiss Webster mice (Mus musculus). Twenty Swiss Webster Mice of about the same age were used as experimental animals. They were divided equally to comprise four different treatments including one control. Each treatment as well as the control consists of five Swiss Webster Mice that serves as replicates. Based on the results, irradiated Swiss Webster mice experienced weight loss and death after ten days of observation. Irradiated Swiss Webster mice experienced erythema. Irradiated Swiss Webster mice experienced hair loss. Histological examination of the large intestines of treatment 1 and 2 reveals presence of fluid in the lymphatic nodule, showing breakage in serosal wall, presence of hemorrhage in the mucosa, misaligned outer longitudinal muscle layer, inflammatory cells and enlarged inflammatory cells

Histological Assessment of the Effect of Mobile Radiation in White mice (Mus musculus) Linn.

Roel V. Cabactulan — 2014-01-31

Nowadays mobile phone are widely used as communication device especially for those people who have businesses, but most of the users does not have any idea of what are the possible effects of using the mobile phones frequently for the long duration of hours. As a Radiologic Technology students whoâ€™s soon profession deals with radiation specifically to ionizing radiation are trying to prove that radiation exposure could provide diseases to the human beings. Since our chosen profession deals with radiation, using of cellular phones that have a non-ionizing radiation our group had come up into this study as a stepping stone to prove and to give awareness that too much radiation exposure would lead to cell damages. The objectives of the study are to (1) determining the potential effects of the offspring on pregnant white mice when exposed to mobile radiation, (2) differentiate the potential pathological effects like hemorrhages on female white mice especially the cell of the ovaries using different mobile exposure time and to (3) evaluate the damages in the ovaries of female white mice. Because of this desired study, our group had proved through the results of our experiment that it has several effects towards the cells of human beings such as hemorrhages and edematous fluid. These effects are strongly believed the cause of radiation exposure to the mice.

Melatonin protective effects to the small intestines among X-ray irradiated White Mice (Mus musculus) Linn.

Jennie B. Queda — 2014-01-31

This study examines the radioprotective effects of melatonin towards the small intestine among X-ray irradiated white mice. There are 14 white mice exposed to a different number of X-ray exposures that will contribute damage towards their small intestines and subject to blood stool test. 35 X-ray exposures are identified to damage the small intestines of white mice and have a positive blood in the stool as a result of laboratory test. Another 40 subjects are used and divided into four groups that serve as controls and treatment group to identify the effect of 35 X-ray exposures to white mice with and without melatonin. In conclusion, 35 X-ray exposures damaged the small intestines of white mice which indicate a presence of blood in the stool; pre-treatment of melatonin before irradiation through oral administration has no radioprotective effect. This recommends that the efficacy of oral administration of melatonin as a radioprotective agent of small intestine is low and that intraperitoneal administration is still more effective and recommended based on the original study; more subjects and histopathology study must be used to further validate the study; and radiation dose should be determined by using a dosimeter.
