Oxidative stress and neuroinflammatory process are implicated in pathophysiology of epilepsy as well as epileptogenesis. The α and γ isoform of peroxisome proliferator-activated receptors (PPAR) agonist has been reported to have antioxidant and anti-inflammatory functions. We hypothesized that saroglitazar, a dual PPAR-α and PPAR-γ agonist may ameliorate oxidative stress and neuroinflammatory process in MES induced epileptic rats. A total of 36 rats were randomized to different groups (n=6). Group I served as normal control, while in the remaining groups (group IV, V and VI) animals were pre-treated with saroglitazar for 15 days prior to inducing MES. Group I animals were pre-treated with vehicle and group-III with diazepam (2mg/kg). Epilepsy was induced in rats and time taken for onset of tonic hind limb extension (THLE), duration of THLE, duration of clonic phase and recovery time in seconds were noted. Brain SOD and MDA levels were assessed and immunohistochemical analysis was done to evaluate the expression of inflammatory marker COX-2. Pre-treatment with saroglitazar was effective against tonic clonic seizure in MES treated rats. SOD levels significantly increased and a significant reduction in MDA levels with a remarkable decrease in the uptake of COX-2 antibody were reported. Saroglitazar attenuated MES induced epilepsy and the probable underlying mechanisms are due to the inhibition of oxidative stress and neuroinflammation.
Cyclophosphamide (CP), the most commonly used anti-neoplastic agent causes immunosuppression and toxic effects on various organs that are the limiting factors of cancer treatment. It can be hypothesized that addition of new immunopotentiating agents with detoxification properties would have beneficial role in cancer therapy. Many researchers have proved that, if certain plant products are combined with cancer chemotherapeutic agents, reduce toxicities and improve tumour response. In Ayurveda, Gymnema sylvestre is commonly used for diabetes, obesity and asthma. Also it possesses anti-inflammatory, astringent and digestive properties. Reports on the immunostimulatory activity of Gymnema sylvestre leaves are available from some in vitro and in vivo experiments. With this background the present study was undertaken to evaluate the potential beneficial role of hydro-alcoholic extract of Gymnema sylvestre leaves (GSE) on cyclophosphamide induced immunnosupression in rats. In this experiment, five groups (n=6 in each) of wistar albino rats were randomly divided to receive drugs and vehicle orally for 21 days. Gr I and II received vehicle. Gr III, IV and V were administered with Levamisole 50 mg/kg, GSE 25mg/kg and GSE 50 mg/kg respectively. Except Gr I rats, all rats were injected intraperitoneally with Cyclophosphamide (100mg/kg) on day 9th and 16th of drug treatment. The effects on various organ weights, rise in Haemagglutination titre to Sheep RBC Antigen, delayed type of hypersensitivity (DTH) response to Sheep RBC, percentage of neutrophil adhesion to nylon fibre and phagocytic index from carbon clearance test were evaluated. Humoral and cellular immunity were measured from HA titre and DTH response respectively. It has been observed that, GSE 50 mg/kg significantly increased the antibody titre, percentage neutrophil adhesion and phagocytic index in CP induced immunosuppressed rats. It also restored the CP induced changes in organ weights and the DTH response at 24 and 48 hours of antigen challenge. But these effects were not comparable to that of Levamisole. Our study shows that Gymnema sylvestre reduced the CP induced immunotoxicities and therefore, it could be a safe supplement to cyclophosphamide chemotherapy.
BACKGROUND The Million Death Study Collaborators in the British Medical Journal have estimated that the people living with HIV/AIDS population to be between 1.4-1.6 million. Development of Antiretroviral Therapy (ART) has been one of the dramatic advances in the history of medicine. Among several factors that can affect the ART outcome, adherence to the ART has been cited as a major factor associated with poor outcomes. For ART to have maximum effect greater than 95%, adherence has been suggested. Additionally, non adherence to ART is a major cause of HIV drug resistance. Especially, in the Indian context, adherence to ART is very important due to the sheer number of HIV/AIDS cases, the socioeconomic status, diversity of the population and regions. That is, the socioeconomic challenges faced by patients contribute to nonadherence to ART in India. With this background, this study was done with the primary objective of assessing the level of adherence to the given regimen of ART as per the NACO guidelines and factors influencing adherence. MATERIALS AND METHODS This is a prospective patient record-based study conducted in the Antiretroviral Therapy Centre at MKCG Medical College, Berhampur, from January 2016 to June 2016. Simple random sampling technique was used to select 150 patients' records from the ART Centre of the medical college. The data was collected in a predesigned case record form from the patient card available at antiretroviral therapy centre. The patients were followed up through the patient card for six months from their recruitment. The adherence to treatment was evaluated using the adherence score adopted by NACO where a score of 1, 2 and 3 implied that 95%, 80-95% and <80% of the medication were taken respectively. The adherence score were further analysed with reference to the sociodemographic characteristics and the adverse drug reactions encountered during the therapy. Descriptive statistics was used to analyse and report the data Graph Pad Prism V 2.0 (trial version). RESULTS There was a predominance of male patients over females with the maximum number of cases were in the age group of 35 to 44 years and majority of the subjects are uneducated, married and unemployed. More than 90% patients had an adherence score of 1 (>95% medication taken). Persons with primary education, married individuals and persons without employment had better improvement in adherence score than other groups. Anaemia was the predominant adverse drug reaction encountered. CONCLUSION The findings of this study imply that, to increase the adherence to therapy and reduce dropout the nonadherent groups need to be targeted. This will prevent the development of drug resistance and treatment failure.
