Background: Angiotensin II (Ang II) is a product of renin angiotensin aldosterone system. Angiotensin-II regulates vascular tone, stimulates the release of pro-inflammatory cytokines, activates nuclear factor-kappa B, increases oxidant stress and functions as an inflammatory molecule. Lisinopril an angiotensin converting enzyme (ACE) inhibitor act by inhibiting ACE, decreases angiotensinogen II activity. Hence the present was to evaluate the anti-inflammatory activity of lisinopril. Aims and Objectives: To evaluate the anti-inflammatory activity of lisinopril in albino rats. Materials and Methods: Eighteen Wistar albino rats weighing around 150-200 g of either sex were randomly selected from central animal facility and divided into three groups. The control group received normal saline 25 ml/kg, standard group received indomethacin 10 mg/kg and test group received lisinopril (3.6 mg/kg) orally for 6 days. The animals were subjected to carrageenan induced paw oedema and cotton pellet induced granuloma model. Results: Lisinopril significantly decreased the mean paw oedema in carrageenan induced paw oedema when compared to control and in cotton pellet induced granuloma lisinopril decreased the mean granuloma weight when compared to control. Conclusion: Lisinopril showed anti-inflammatory activity when given for 6 consecutive days per orally in albino rats in carrageenan induced paw oedema and cotton pellet induced granuloma model.
To evaluate the effect of telmisartan on blood glucose levels and blood lipid levels in streptozotocin induced diabetic rats. Eighteen Wistar albino rats weighing 150-200gms of either sex were randomly selected from the central animal facility, and divided into 3 groups. Diabetes was induced by injecting Streptozotocin intraperitonelly. The control group received 1% Gum acacia (oral), standard group received 0.5 mg/kg Glibenclamide (oral) and the test group received Telmisartan 7.2mg/kg body weight (oral) from 0-28 days respectively. Body weight of the individual rats were measured on the respective days before blood glucose estimation on 0, 1, 3, 7, 14, 21 & 28th day and fasting blood glucose was estimated by (ACCUCHECK) glucometer. Estimation of fasting lipid profile by lipid screening strips on 1st and 28th day. When compared to control the capillary blood glucose (CBG) levels in the Telmisartan group was less at all the intervals but comparable with that of standard drug Glibenclamide in Streptozotocin induced diabetic rats. Improved lipid profile was seen with the Telmisartan group when compared to control group in Streptozotocin induced diabetic rats. Hypoglycemic activity and improved lipid profile action was seen with Telmisartan group which is comparable to standard drug glibenclamide in streptozotocin induced diabetic albino rats.
The aim was to evaluate the analgesic activity of perindopril in chemical, thermal and mechanical pain on Swiss albino mice. A total of 54 albino mice (Swiss strain) weighing 25-30 g were allocated to each experimental model and in each model there were three groups. The control group received normal saline (25 ml/kg) per orally, standard group received pentazocine (10 mg/kg) intra-peritoneal and test groups received perindopril (1 mg/kg) per orally. Perindopril and normal saline was administered 2 h before, whereas the pentazocine was administered 15 min prior to Eddy's hot plate, writhing and tail clip methods. The decrease in number of writhes, the delay in reaction time in tail clip and Eddy's hot plate method denoted the analgesic activity. Perindopril decreased the number of writhes, delayed the reaction time in tail clip and Eddy's hot plate method considerably when compared with control (normal saline), but less when compared with standard (pentazocine). Perindopril exhibits analgesic activity in thermal, chemical, and mechanical pain models in albino mice.
Background: Angiotensin II (Ang II) is a product of Renin angiotensin aldosterone system (RAAS). Angiotensin‑II regulates vascular tone, stimulates the release of pro‑inflammatory cytokines, activates nuclear factor‑kappa B (NF‑κB), increases oxidant stress and functions as an inflammatory molecule. Ramipril an ACE inhibitor act by inhibiting angiotensin converting enzyme, decreases angiotensinogen II activity. Hence the present was to evaluate the anti-inflammatory activity of Ramipril.Methods: Eighteen Wistar albino rats weighing around 150-200gms of either sex were randomly selected from central animal facility and divided into three groups. The control group received normal saline 25ml/kg, standard group received Indomethacin 10mg/kg and test group received Ramipril (0.9mg/kg) orally for six days. The animals were subjected to carrageenan induced paw oedema and cotton pellet induced granuloma model.Results: Ramipril significantly decreased the mean paw oedema in carrageenan induced paw oedema when compared to control and in cotton pellet induced granuloma Ramipril decreased the mean granuloma weight when compared to control.Conclusions: Ramipril showed anti-inflammatory activity when given for 6 consecutive days per orally in albino rats in carrageenan induced paw oedema and cotton pellet induced granuloma model.
Objective: To evaluate the effect of Edrophonium on blood glucose levels in euglycemic albino rats through OGTT. Materials and Methods:Twelve Swiss albino rats weighing around 150-200 gms of either sex were randomly selected from the central animal facility, JSSMC, Mysore and divided into two groups. The control group received distilled water (25ml/kg body wt.) per orally, test groups received Edrophonium (6.3mg/ kg/day) intravenously for five days. On the fifth day, following overnight fasting, half an hour after drug administration in all the groups of rats Oral Glucose Tolerance Test was performed, by administering oral glucose in dose of 0.6gm/kg body weight. The capillary blood glucose levels were measured at 0, 60 and 150 min, by rat tail snipping method using (ACCUCHEK) glucometer.
