ABSTRACT

Objectives: The study aimed to explore the in vivo protective potential of rosuvastatin (ROSS), an oral antihyperlipidemic drug against doxorubicin (DOXO) induced cardio toxicity in rats. Materials and Methods: Cardiac toxicity was induced by DOXO injection (10 mg/kg, i.p.), once on the 20th day of the experiment. Except for the control rats, all were received DOXO and the study was continued for up to 21 days. The influence of ROSS on acute treatment was analyzed by quantification of cardiac marker enzymes such as creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and liver marker enzymes like aspartate aminotransferase (AST), alanine aminotransferase (ALT) along with the measurement of in vivo antioxidants like superoxide dismutase and catalase. To observe histological changes of myocardial tissue hematoxylin and eosin staining were used. Results: Acute administration of DOXO resulted in a marked rise of cardiac marker enzymes that confirms the myocardial damage compared to control animals whereas administration of ROSS (10 mg/kg, p.o.) resulted in the significant reduction of CK-MB, LDH levels (p<0.05) and AST, ALT levels to a remarkable extent. Moreover, ROSS administration significantly increased the activities of various in vivo antioxidant levels. Conclusion: From the results, the acute administration of ROSS showed significant cardioprotective property, which was evidenced by a significant reduction of cardiac and liver marker enzymes along with significant improvement of in vivo antioxidant activities. Furthermore the results were supported with histopathological observations. Hence, it can be concluded that cardioprotective potential of ROSS may be through attenuation of oxidative stress by modulating oxidative damage in rats.

ABSTRACT

PURPOSE: The aim of this study was to compare the clinical efficacy of injection of 2 long-acting amide local anesthetic agents - bupivacaine and ropivacaine with and without 4 mg dexamethasone in patients undergoing third molar extraction. METHODS: A prospective randomized double blind controlled trial was conducted among 68 patients with impacted mandibular third molars. Group A and B were the control groups and received 1.8 mL of 0.5% bupivacaine hydrochloride and 0.75% ropivacaine hydrochloride, respectively. Group A1 and B1 were experimental groups and received modified twin mixes which were 1.8 mL of 0.5% bupivacaine hydrochloride + 1mL/4mg dexamethasone and 0.75% ropivacaine hydrochloride + 1 mL/4mg dexamethasone, respectively. Visual analog pain scale, mouth opening measurement and facial swelling were assessed at the time of injection and postoperative days 1, 3, and 7. RESULTS: The mean visual analogue scale score for pain on local anesthesia injection was found to be less in both experimental groups- Group A1 (2.94) and B1 (2.41) as compared to control groups- Group A (3.59) and B (3.06). The durations of soft tissue anesthesia were higher as compared to their respective controls for both Group A1 and B1. Patients in both control groups A and B had an increased postoperative swelling, pain and trismus. CONCLUSIONS: Intraoperative and postoperative comfort in both the experimental groups were higher than those for control groups, thereby establishing the clinical efficacy of both modified twin mixes for use in surgical extraction of mandibular third molars.

ABSTRACT

The aim of this triple blinded randomized clinical trial was to evaluate the efficacy of tranexamic acid when used in conjunction with hypotensive anaesthesia exclusively for Le Fort I osteotomies. 49 patients undergoing Le Fort I osteotomy for correction of dentofacial deformity were divided into two groups; Group 1 received a placebo of saline 5 ml and Group 2 received 10 mg/kg body weight of tranexamic acid. The operating surgeon, anaesthetist and investigator were blinded. The variables of interest recorded in this study included the change in Hb%, PCV, total blood loss, total operating time and quality of the surgical field using Fromme's Ordinal Scale. Statistically significant differences between the two groups were found between the following variables: post-operative Hb%, drop in Hb%, post-operative PCV, drop in PCV, total surgical blood loss, total operating time and quality of surgical field (P < 0.05). Group 2 patients exhibited a smaller drop in Hb% and PCV, with a lower Fromme's Ordinal Scale value and decreased total blood loss and operating time. In conclusion single preoperative administration of tranexamic acid in the dose of 10 mg/kg, when combined with hypotensive anaesthesia is effective in controlling blood loss with regards to single piece Le Fort I surgery.
