XXVI CECIM WILC ORIGINAL RESEARCH Psychoactive Substance Use In The Faculty Of Health In Sur- colombiana University, Period 2014 - 1. Ana María Gómez Aroca, Adriana Zamora Suarez. Scientific Society: Organización Científica de Estudiantes de Medicina de la Universidad Surcolombiana, OCEMSUR. Introduction: The psychoactive substance use represents a problem of high public health impact in universities, especially among stu- dents of health sciences, which reframes the dimension of factors related to consumption, their consequences and the intervention measures towards it. Objective: Determine the prevalence of con- sumption and characterize the related variables towards it. Methods: A descriptive cross-sectional study conducted during the academic year of 2014-1. An adapted survey from WHO was applied to 825 students. 375 of them were discarded due to failures in completing the survey. Results: From total population: 46.33% were men and this group had the highest intake of alcohol (53.59%). Cigarette use was more frequent in women (53.66%). The age of onset ranged from 16- 20 years (52.88%). The most used illegal psychoactive substance was marijuana (14.25%). The main reason for the consumption was fun (36.43%), followed by depression (8.51%), anxiety (7.72%), and aca- demic difficulties (5.54%). Discussion: Psychoactive substance use sets out the challenges in front of low educational achievements, depression, anxiety and substance abuse. Conclusions: Efforts to modify the increasing consumption are unsatisfactory, which neces- sitates the approach of new strategies.

Lately it has increased its resistance, considering the bacte- riophages as therapeutic alternative. Objective: To establish the experimental conditions for the isolation of phage for Salmonella sp. in samples taken from manure G. gallus. Methods: Study type, technological transfer. Manure samples and soil be took from a farm of Calarca. Phage was isolated by two methods, one centrifugation, adding PEG, NaCl and meat extract; other microfiltration (filter 0.45 .mu.m). Later by plaque technique coculture was determined. Re- sults: Salmonella was obtained from a clinical isolate and a donation from Dr Manuel Alfonso Patarroyo (ATCC). Bacteriophages obtained by these two methods were cocultivated with both Salmonella thypi, observing the presence of phage in the plaques. Discussion: With the microfiltration was observed between 4 and 10 pfu and bald small (0.5 to 1 mm), with best results in the clinical isolate. Consistent with the literature, many enterobacteria phages used as hosts gene- rate bald difficult to observe. The Centrifugation method increased the number of plaques (10-15 pfu). Conclusion: The two isolation methods showed results, but was more effective centrifugation. Pha- ges acted against the two strains of Salmonella, however had greater activity against clinical isolate. Keywords: Salmonella, Bacteriophages, Gallus gallus.

Introduction: Heart defects are the most common birth defects in humans. Maternal obesity is associated with abnormalities in cardiac development, but the mechanisms involved are unknown. Matrix metalloproteinase-2 (MMP-2) plays an important role in cardiogene- sis. Objective: To evaluate the expression pattern of MMP-2 during late cardiogenesis in normal-weight and obese rats. Methods: Expe- rimental study. A model of obesity was established in adult female Wistar rats by feeding them a high-calorie diet. Obese rats (OB) and controls (CTROL) were mated with healthy males and were sacrificed on day 16.5 of gestation. Fetal hearts were processed for the de- tection of MMP-2 by immunohistochemistry. To analyze the density and distribution of MMP-2 the integrated optical density (IOD) was evaluated. Results: A significant decrease in the expression pattern of MMP-2 was observed in the ventricles of the OB fetal hearts com- pared with CTROL (IOD OB: 10.45 ± 0.73, CTROL: 13.59 ± 0.72, p<0.05). In contrast, immunostaining of MMP-2 in the atria was similar in both groups (OB: 15.19 ± 2.22, CTROL: 13.66 ± 2.10; NS). The expres- sion of MMP-2 was equivalent in the four heart chambers of CTROL, while in OB the ventricles showed a decreased MMP-2 expression relative to the atria. Conclusion: This study revealed alterations in the expression pattern of MMP-2 associated with obesity, which may be a key factor in the increase in congenital heart defects caused by this disease.

Introduction: The thyroid gland is located in the anterior neck. It's shaped like U or H and of two lobes: left and right, joined by the isthmus. Occasionally there is a pyramid lobe, which is an anato- mical variant. In the adult dimensions are 4 to 6 cm x 2 cm x 2 cm craniocaudal, sagittal and transverse direction respectively. At the level of the isthmus, measuring less than 0.3 cm in anteroposterior sense. However, dimensions outside this range does not necessarily mean a thyroid pathology. Methods: A descriptive cross-sectional study, a sample of 8 complete corpses was performed. After dissec- ting the thyroid glands, their qualitative and quantitative variables were characterized. Descriptive statistics were used to data analy- sis. Results and Discussion: Corpses were recruited, which two had pyramidal lobe with a length of 5.7 ± 0.85. The length of left to right lobe was 6.39 cm ± 1.95 cm. An average of 1.4 cm ± 0.64 cm for the length of the isthmus was recorded upper to higher. Conclusions: Of- ten, the organogenesis of the thyroid gland is altered, which lead to the development of multiple morphological variations of the glands known as Thyroid dysgenesis. Additionally there are changes due to changes in thyroid migration. The normal length of the thyroid gland depends on variables such as age and geographic distribution, hence the importance of knowing their prevalence in our population.
