Students' Perception of Online Platform Based Tutorial in Physiology Curriculum

Tutorial is one of the effective ways of interactive small group teaching activity sessions. The tutorial is a short series of classes that is ideally conducted in the small group. The use of media in the form of online platforms in tutorials could be very useful. Aims of the study to evaluate the response and perception of students about the small group learning activities like Online platform tutorials in the medical undergraduate Physiology curriculum. This was the cross-sectional study done in the Physiology Department, AIIMS, Bhopal, India from 2022 to 2023 which involved first-year MBBS students (n=39). Five online platforms-based tutorials were taken whereby five topics- one for each system were discussed. In this form of tutorial, 20 to 25 minutes were focussed on discussion, followed by assessment by multiple choice questions through an online platform. Perceptions of students were assessed through a predesigned validated questionnaire, which involved open-ended and close-ended questions. Likert scale questionnaires were also used. The chi-square test and odds ratio was used to see the difference between categorical variable (yes vs. no). The mean and Median score of the Likert scale was reported. The major issue faced was the failure to promote writing skills followed by connectivity problems. Seventy-eight percent (78.0%) of participants liked this form of tutorial, and 94.0% of participants advocated using it in the future. Online platform-based tutorials motivated 84.0% of students to learn topics in a better way. However, 41.0% feared that it does not involve communication and 92.0% opined that writing skill is not promoted. Online platform-based tutorials should be used in the Physiology curriculum. However, infrastructure in the form of prior training and internet connection must be provided. Conventional forms of tutorial should also be used to promote communication and writing skills.

Histomorphometric demonstration of the effect of chronic use of nonsteroidal anti-inflammatory drugs-ibuprofen on mucosa of small intestine

The purpose of this study was to ascertain change in structure of mucosa of small intestine, if any, in small intestine of Swiss albino mice as an effect of chronic use of nonsteroidal anti-inflammatory drugs–Ibuprofen. Longitudinal study conducted on 46 adult Swiss albino mice, 23 as experimental and 23 as control. Ibuprofen was given at a dose of 40 µg/g body weight per day for 6 weeks by intragastric route in experimental group of mice while control group of mice received same volume of distilled water. Mice of both the groups were sacrificed and desired segments of small intestines were dissected out and tissues were subjected to histological processing. Histomorphometry was performed and relevant photomicrographs were obtained. Student's unpaired t test by GraphPad Prism 6 software. Height of villi was not significantly altered but there was significant reduction of the number of goblet and non-goblet cells (enterocytes and other columnar cells) in mucosal lining of the small intestine of experimental group of mice. Percent distribution of the goblet and non-goblet cells was not altered in villi of two groups. Chronic exposure of Ibuprofen in therapeutic dosage caused reduction of the functional cell mass in lining epithelium of villi of middle segment of small intestine. However, there was no evidence of ulcerative or hemorrhagic lesion.
