Semiquinone fraction isolated from Bacillus sp. INM-1 protects hepatic tissues against γ-radiation induced toxicity.

Present study was focused on evaluation of a semiquinone glucoside derivative (SQGD) isolated from radioresistant bacterium Bacillus sp. INM-1 for its ability against γ radiation induced oxidative stress in irradiated mice. Animals were divided into four group, i.e., (i) untreated control mice; (ii) SQGD treated (50 mg/kg b. wt. i.p.) mice; (iii) irradiated (10 Gy) mice; and (iv) irradiated mice which were pre-treated (-2 h) with SQGD (50 mg/kg b. wt. i.p.). Following treatment, liver homogenates of the treated mice were subjected to endogenous antioxidant enzymes estimation. Result indicated that SQGD pre-treatment, significantly (P < 0.05) induced superoxide dismutase (SOD) (19.84 ± 2.18% at 72 h), catalase (CAT) (26.47 ± 3.11% at 12 h), glutathione (33.81 ± 1.99% at 24 h), and glutathione-S-transferase (24.40 ± 2.65% at 6 h) activities in the liver of mice as compared with untreated control. Significant (P < 0.05) induction in SOD (50.04 ± 5.59% at 12 h), CAT (62.22 ± 7.50 at 72 h), glutathione (42.92 ± 2.28% at 24 h), and glutathione-S-transferase (46.65 ± 3.25 at 12 h) was observed in irradiated mice which were pre-treated with SQGD compared with only irradiated mice. Further, significant induction in ABTS(+) radicals (directly proportional to decrease mM Trolox equivalent) was observed in liver homogenate of H2 O2 treated mice which were found to be significantly inhibited in H2 O2 treated mice pre-treated with SQGD. Thus, it can be concluded that SQGD treatment neutralizes oxidative stress caused by irradiation not only by enhancing endogenous antioxidant enzymes but also by improving total antioxidant status of cellular system and thus cumulative effect of the phenomenon may contributes to radioprotection.

Comparative study of analgesia of ketorolac, tramadol, and flupirtine in the management of third molar surgery.

Introduction: The most commonly performed surgical procedure in most oral and maxillofacial surgery practices is the removal of third molars. Postoperative pain is considered a form of acute pain due to surgical trauma with an inflammatory reaction. Materials and Methods: One hundred and fifty patients were included in the study which were divided into GROUP-A, B, and C-50 patients each; those who underwent third molar removal under local anesthesia. Local anesthesia was obtained by inferior alveolar, lingual, long buccal, posterior superior alveolar, and greater palatal nerve block injections after first complain of pain, all patients were prescribed analgesics (Ketorolac-10 mg), (Tramadol-50 mg), (Flupirtine-100 mg), and antibiotics co-amoxiclav-625 mg) T. D. S in all the three groups A, B, C, respectively, for 5 days and the timing noted in the patients assessment sheet. The statistical analysis was done using SPSS Version 15.0 statistical analysis software. Results: The flupirtine group has early onset and also had minimum side effects. All the groups showed similar trend in change in pain score from 3 h. P. O to different time intervals. It was observed the pain score increased significantly till 6 h. Post operative a decreased trend was found at 24 h, 48 h, 78 h, after 6 h. and this change was found to be statistically significant for all three groups. Conclusion: Flupirtine had faster onset and comparable pain management profile as compared to tramadol, it also had minimum side effects, hence the use of flupirtine might be recommended for postoperative pain management in cases undergoing third molar surgery.

Assessment of psychiatric co-morbidities in patient of bronchial asthma attending a tertiary medical centre (Multicentric study).

AIMS AND OBJECTIVES: Asthma is a chronic inflammatory condition, which is associated with increase in airway hyper responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing. Asthma is a very common respiratory illness, in which some of the disease related factors may increases the vulnerability to psychiatric disorders. This study was done to determine the prevalence of psychiatric co-morbidity in patients of bronchial asthma. METHODOLOGY: It is an observational study conducted in 110 follow-up patients of bronchial asthma attending respiratory medicine OPD at tertiary care centre in central India. Psychiatric co-morbidities are assessed by pre-designed short-structured questionnaire using Mini international neuropsychiatric interview. RESULT: Among 110 patients of bronchial asthma 28% had psychiatric co-morbidity mainly depressive episode (59%). A significant association is found between lower socioeconomic status (P = 0.01), duration of of active illness (more than 1 year) (P = 0.001), and age of patient above 60 years (P = 0.001) with psychiatric co-morbidity of asthma patient. CONCLUSION: Our study shows there is increased prevalence of psychiatric co-morbidities in patients of bronchial asthma, higher than the national average. The predominant psychiatric disorder seen is depressive disorder, so treatment of asthma should be a multidisciplinary approach including medical treatment of asthma and psychiatric evaluation to prevent psychiatric co-morbidity or its early management. This will greatly reduce the morbidity, visits to hospital, expenditure on treatment and thereby having better outcomes in our patients of asthma.
