Objective: The present study aims to evaluate antioxidants and protective role of Cassia tora Linn. against oxidative stress-induced DNA and cell membrane damage. Materials and Methods: The total and profiles of flavonoids were identified and quantified through reversed-phase high-performance liquid chromatography. In vitro antioxidant activity was determined using standard antioxidant assays. The protective role of C. tora extracts against oxidative stress-induced DNA and cell membrane damage was examined by electrophoretic and scanning electron microscopic studies, respectively. Results: The total flavonoid content of CtEA was 106.8 ± 2.8 mg/g d.w.QE, CtME was 72.4 ± 1.12 mg/g d.w.QE, and CtWE was 30.4 ± 0.8 mg/g d.w.QE. The concentration of flavonoids present in CtEA in decreasing order: quercetin >kaempferol >epicatechin; in CtME: quercetin >rutin >kaempferol; whereas, in CtWE: quercetin >rutin >kaempferol. The CtEA inhibited free radical-induced red blood cell hemolysis and cell membrane morphology better than CtME as confirmed by a scanning electron micrograph. CtEA also showed better protection than CtME and CtWE against free radical-induced DNA damage as confirmed by electrophoresis. Conclusion: C. tora contains flavonoids and inhibits oxidative stress and can be used for many health benefits and pharmacotherapy.

Background: Guggulsterone (GS) is a plant steroid and bioactive compound present in gum Guggul of Commiphora wightii. An Indian herbal medicine system “Ayurveda” has a long history of use of gum Guggul and plant extract of C. wightii as medicine for the treatment of various illnesses. Complex nature, low availability, and inconsistency of phytoconstituents make its analysis of difficult tasks. Aims: In this work, six different Guggul-based herbal formulations were examined for estimation of GS and their isomers (E and Z) through high-performance thin-layer chromatography technique. Materials and Methods: For that various concentrations of standard E-GS and Z-GS (50 ng–250 ng/spot) with samples (20 μg/spot) were applied on silica gel coated aluminum plate and developed with the mobile phase of toluene: ethyl acetate: formic acid: methanol (6:2:1:0.5). The scanning was performed at 254 nm wavelength and the absorbance (scan) spectrum of E-GS and Z-GS peak was generated at 200 nm–400 nm wavelength range. Results and Conclusions: Rf value and scan spectrum pattern of the samples reveal that they contain either one form of GS (E-GS, Z-GS) or both. The quantity of E-GS and Z-GS within the samples was ranged from 0.230 ± 0.0040–0.926 ± 0.0168% to 0.537 ± 0.0026–0.723 ± 0.0177%, respectively.

Introduction: The association between secondhand smoke and health outcomes, such as frequent respiratory infections, ischemic heart disease, lung cancer, asthma, and stroke, has long been established. The study aimed to estimate the prevalence of secondhand smoking exposure among higher secondary school students in Ernakulam district, Kerala, Southern India. Materials and Methods: A structured questionnaire was administered to all students from four randomly selected higher secondary schools in Ernakulam district. Descriptive statistics was done using frequencies and percentages. Univariate and multivariate analyses were done for factors associated with household exposure to tobacco smoke generating odds ratios (ORs) and 95% confidence intervals (CIs). Results: A total of 629 students participated in the study. The prevalence of ever smokers was 11.9% and of current smokers was 5.2%. Among the study participants, 23.2% were exposed to secondhand smoking from a family member and 18.8% from friends. Lower educational status of father was associated with the household exposure to secondhand smoke (adjusted OR 4.51 [95% CI 1.66–12.22]). More than half of the study participants (56.3%) reported that they were exposed to cigarette smoke in past 1 week in a public place and 10.2% in closed public places. Nearly one-third of the students reported that they have seen somebody smoking inside school campus in the past 30 days. Conclusion: Exposure to secondhand smoke at home, schools, and public places was higher among the late adolescent higher secondary school students in Ernakulam district. The findings underscore the urgent need for increased efforts to implement the strategies to reduce secondhand smoke exposure among adolescents.

Background: There are limited data available on how the problem of alcohol use is detected in primary care setting in India. Particularly in Odisha, it has not been investigated yet. This study was conducted to determine the prevalence of drinking, drinking patterns, and quitting behavior among the male patients visiting a primary health-care facility in a district of Odisha. Methodology: A cross-sectional study was conducted among patients attending community health center (CHC), Buguda in the state of Odisha, India, from December 1, 2014, to February 31, 2015. Patients above 18 years of age, conscious, and willing to participate in the study were included in the study, while those with cognitive impairment and critically ill were excluded from the study. All eligible consecutive patients attending outpatient department of CHC were invited to participate while they came out after physician's consultation. A pilot study was conducted prior to the study. Informed verbal consent from each patient was obtained before the interview. The study was approved by the Institutional Ethics Committee of Indian Institute of Public Health, Bhubaneswar. Results: A total of 431 patients were interviewed. Our study showed 38% (95% confidence interval [CI]: 33.5%–42.7%) of respondents were alcoholic and of those 60% (95% CI: 51.4%–66.5%) were hazardous drinkers. One in five patients had a history of alcoholics in their family, and a similar proportion of participants were heavy workers. Smokers were eight times (adjusted odds ratio [AOR] =7.56; 4.03–14.52) more likely to be alcoholics as compared to nonsmokers (P < 0.001), whereas the prevalence of alcohol drinking was four times (AOR = 3.94; 2.25–6.92) higher in smokeless tobacco users compared to nonusers. Conclusion: Focusing only on counseling and treatment services will not reduce the piling burden of alcohol use. It is important to target the environment that leads to such habits.

Objective: The present study was aimed to investigate the neuroprotective effects of Decalepis hamiltonii (Dh) aqueous root extract and its compounds against age-related oxidative stress (OS) in the discrete regions of the rat brain. Materials and Methods: Male Wistar albino rats of 4- and 22-month-old were divided into control and six supplemented groups. The supplemented groups were orally administered with ellagic acid (EA), 4-hydroxyisophthalic acid (4-HIA), and Dh extract for 30 days. Results: Age-related decrease in antioxidant enzyme activities was noticed. The hippocampus was found to be more vulnerable to OS as seen by the elevation in the OS markers. Supplementation of the Dh extract, EA, and 4-HIA was found to be effective in up-regulating the antioxidant status. However, the extent of up-regulation was more evident in Dh supplemented animals. Conclusion: Our results suggest that Dh extract and its compounds exhibit neuroprotective effects against age-related OS and can be used as a dietary therapeutic intervention for the treatment of neurological disorders.

Aims: Carvedilol phosphate (CDP) is a nonselective beta-blocker used for the treatment of heart failures and hypertension. In this work, moisture sorption–desorption characteristics and thermodynamic properties of CDP have been investigated. Materials and Methods: The isotherms were determined using dynamic vapor sorption analyzer at different humidity conditions (0%–90% relative humidity) and three pharmaceutically relevant temperatures (20°C, 30°C, and 40°C). The experimental sorption data determined were fitted to various models, namely, Brunauer–Emmett–Teller; Guggenheim-Anderson-De Boer (GAB); Peleg; and modified GAB. Isosteric heats of sorption were evaluated through the direct use of sorption isotherms by means of the Clausius-Clapeyron equation. Statistical Analysis Used: The sorption model parameters were determined from the experimental sorption data using nonlinear regression analysis, and mean relative percentage deviation (P), correlation (Correl), root mean square error, and model efficiency were considered as the criteria to select the best fit model. Results: The sorption–desorption isotherms have sigmoidal shape – confirming to Type II isotherms. Based on the statistical data analysis, modified GAB model was found to be more adequate to explain sorption characteristics of CDP. It is noted that the rate of adsorption and desorption is specific to the temperature at which it was being studied. It is observed that isosteric heat of sorption decreased with increasing equilibrium moisture content. Conclusions: The calculation of the thermodynamic properties was further used to draw an understanding of the properties of water and energy requirements associated with the sorption behavior. The sorption–desorption data and the set of equations are useful in the simulation of processing, handling, and storage of CDP and further behavior during manufacture and storage of CDP formulations.

Introduction: The aim of this study was to investigate the influence of the milling process on the solubility of efavirenz. Materials and Methods: Milling process was done using Nanomilling for 30, 60, and 180 min. Intact and milled efavirenz were characterized by powder X-ray diffraction, scanning electron microscopy (SEM), spectroscopy infrared (IR), differential scanning calorimetry (DSC), and solubility test. Results: The X-ray diffractogram showed a decline on peak intensity of milled efavirenz compared to intact efavirenz. The SEM graph depicted the change from crystalline to amorphous habit after milling process. The IR spectrum showed there was no difference between intact and milled efavirenz. Thermal analysis which performed by DSC showed a reduction on endothermic peak after milling process which related to decreasing of crystallinity. Solubility test of intact and milled efavirenz was conducted in distilled water free CO₂with 0.25% sodium lauryl sulfate media and measured using high-performance liquid chromatography method with acetonitrile: distilled water (80:20) as mobile phases. The solubility was significantly increased (P < 0.05) after milling processes, which the intact efavirenz was 27.12 ± 2.05, while the milled efavirenz for 30, 60, and 180 min were 75.53 ± 1.59, 82.34 ± 1.23, and 104.75 ± 0.96 μg/mL, respectively. Conclusions: Based on the results, the solubility of efavirenz improved after milling process.
