Comparative evaluation of various analgesic drugs in Wistar rats used as a teaching tool to teach animal experiments to post graduate MD Pharmacology students

Background: Postgraduates when join Pharmacology department, they don’t have much idea about guidelines and methods to do animal experiments. This study was designed to sensitize postgraduate students to animal experiments by evaluating the anti-inflammatory effects and the efficacy of diclofenac, tramadol and etoricoxib in reducing paw edema in wistar rats.Methods: The wistar rats of 225-250gram were divided into four groups (n=10 each). In all the groups the paw edema on right paw was created using 0.1ml of 1% formalin subcutaneously. Group 1 rats (control), group 2 were given diclofenac, group 3 were given tramadol and group 4 were given etoricoxib orally. The parameters assessed were water displacement in plethysmography after 2, 4, 24, 48 hours of giving the drug. The circumference of edematous paws after 4 hours, licking of paw was observed over 30minutes of giving the drug and was compared. Pre and post study feedback were obtained from the students by using a preformed questionnaire to assess the knowledge gained by the students.Results: The test showed that all the drugs were effective in reducing inflammation, circumference of edema and the licking duration significantly (p<0.05). The post study answering of questions by postgraduate was 100% in comparison to pre-study answering which was 33%.Conclusions: A short animal study conducted as a teaching tool to postgraduate students was able to teach the guidelines of animal experiments and handling of animals effectively.

Haematological Indices

Solanum gilo (eggplant) is an edible vegetable whose leaf is reported to possess numerous medicinal properties due to its rich constituents. Against this backdrop, there is possibility that its consumption may have effect on haematological indices. Therefore this research sought to assess the effect of Solanum gilo leaf diet on some haemotological indices of albino wistar rats. About twenty four (24) albino wistar rats weighing between 120-150mg were randomly assigned into four groups of six animals each. Each rat was allowed to drinking water ad labitum. Control group received normal rodent chow while group 2 was fed 5% Solanum gilo diet. Group 3 was fed 10% Solanum gilo diet and group 4 received 20% Solanum gilo diet. The different diets were prepared by mixing different proportions of ground S. gilo leaves with rodent chow. Automated blood cell analyzer (Model PCE 210, Japan) was used for analysis of haematological parameters. Preliminary study on its proximate composition, showed the appreciable presence of crude fat, protein, fibre and carbohydrate. Consumption of S. gilo caused significant improvement in some blood parameters; notably packed cell volume (PCV), white blood cell (WBC) and platelet counts. Hence, eggplant is a nutritious vegetable with healing, the therapeutic and immunity properties. If exploited in human diet has the potentials of improving quality of life.

Background: We investigated whether the frequency of lower urinary tract symptoms (LUTS) increased in patients in whom double-J stents were applied. We also evaluated several medical therapy protocols to treat symptoms related with ureteral stents.Materials and Methods: A total of 108 patients, in whom unilateral double-j stent was applied during ureteral stone treatment, were included. Before the double-J stent was applied, all patients completed storage components of the “International Prostate Symptom Score” (IPSSs), quality of life components of the IPSS (IPSS-QOL) and “Overactive Bladder Questionnaire” (OABq) forms and scores were calculated. After the procedure, cases were randomized into 5 groups, an antiinflammatory was given to Group 1, spasmolytic to Group 2, anticholinergic to Group 3 and α-blocker to Group 4. No additional drug was given to Group 5 as this control group. During the fourth week of the procedure, IPSSs, IPSS-QOL and OABq forms were again completed and scores were compared with the previous ones.Results: When all the cases were evaluated, the IPSSs, IPSS-QOLand OABq scores of patients in whom the double-J stent was applied were statistically significantly higher the procedure. Compared to the control group, the cases where the double-J stent was applied showed a higher IPSSs, IPSS-QOL and OABq scores and none of the medical therapies could prevent this increase.Interpretation: The frequency of LUTS increased in cases where the ureteral stent was applied and discomfort continued as long as the stent stayed in the body.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats. A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.
