ABSTRACT
The human bodies and organs have traditionally been preserved using formalin solution, although it irritates the eyes, nose and throat. Plastination is an unique and expensive method for preserving biological samples that can be used in teaching and research. Therefore, the goal of the current study was to prepare a costeffective solution using thermocol to plastinate the brain specimens as a supplement for teaching and research. Two human brains were used in this pilot research project. According to standard procedures, the brains were first fixed in 10% formaldehyde, sectioned horizontally, sagittally and coronally dehydrated in acetone, and then immersed in the plastination solution at room temperature and pressure. Then the specimens were airdried at room temperature. A team of 62 Anatomists and Pathologists assessed the quality of the specimens using a self-developed grading scale. The grading was provided based on the specimens’ clarity, stability, aesthetic look, colour and smell. Statistical analyses was performed using SPSS software, Kruskal Wallis test showed that the lowest mean score was 4.04 provided for colour and highest mean score was 5 provided for the smell with a statistically significant p<0.001. Thus our plastinated specimens were of good quality, durable and handlefriendly. Our study demonstrated that the cost-effective plastination solution (CEPS) procedure is an inexpensive and efficient way to create plastinated specimens that are appropriate for teaching neuroanatomy.
ABSTRACT
Assessment drives learning, For the past years, we have been using an Traditional oral exam i.e. one examiner or tow examiner taking oral examination of one student, as a part of the examination process for the First MBBS formative and summative assessment. There appears to be tremendous variation on what constitutes the "traditional" oral examination. Studies analyzing characteristics of oral examinations vary most often by format and number of examiners. Considering above pros and cons of traditional oral examination and on the basis of examiners’ feedback, the new format of viva voce examination is started in the form of “Small Group Structured Oral Examination”(SGSOE). In SGSOE Students will be divided in the small group of 10 to 12 students in each group. They have to sit in chronological order in group. Two examiners will be assigned to group . For examination, according to roll no, they have to randomly select a chit from box. Than student has to give answer of main question mention in structured viva card of the topic Than rest of the students one by one, has to give answer of leading question related to that topic. after completion of Group Viva (GV) group of two examiner present at group viva will decides Marks, depending number of topic attend by all the students. Thus, It is one of the new exam systems designed to make an objective, valid and reliable assessment of different components of subject.
ABSTRACT
Vapours of embalming fluid in the dissection room are a perennial cause of irritation to the mucous membranes of the pharynx, upper respiratory tract and eyes. We made an attempt to assess the discomfort level produced by formalin and that produced by the standardized embalming fluid used in our department. A list of twenty symptoms was made and circulated among students attending dissection and students were asked to grade the severity of each symptom experienced on a scale of 1 to 4. Individual scores of each symptom were statistically compared and summated, and the same reflected the general acceptability of the embalming fluid.
