Abstract: The demand for orally disintegrating tablets of lamotrigine has been growing during the last decade especially for the geriatric and pediatric patients. Lamotrigine is a recognized drug for epilepsy, so development of an ODT of lamotrigine and to evaluate the effect of various superdisintegrants on its disintegration time and release profile was the prime objective of this research work. Tablets were prepared by direct compression technique using 3 different superdisintegrants. Sodium starch glycolate, Croscarmellose sodium and Crosspovidone XL-10 were used as superdisintegrants in combinations to achieve optimum release profile, disintegration time and hardness. Direct compression process was selected for this formulation of ODT tablets, because porous nature is more in direct compression blend than wet granulation blend, so it will give faster disintegration. Microcrystalline cellulose was used as diluent and mannitol, mint flavor and sodium saccharin were used to enhance the organoleptic properties of tablets. The tablets were evaluated for weight variation, hardness, friability, in-vitro disintegration time and drug release characteristics. Hardness and friability data indicated good mechanical strength around 3 kg/cm 2 for all the batches. The results of in-vitro disintegration time indicated that the tablets dispersed rapidly in mouth within 8 s. Dissolution study revealed release rate of drug from the tablets was comparable with marketed tablet formulation of lamotrigine. It was concluded that superdisintegrants addition technique is a useful method for preparing orally disintegrating tablets by direct compression method.[...] Read More.

Abstract: The evaluation of the crude herbal drug which eventually enters the pharmaceutical market is obviously of considerable importance. This operation involves the identification of the material and determination of its quality, purity and of adulterated nature of the adulterants. The present paper is based on the above objectives which confined to chemotaxonomic authentication of Cyprus rotundus L. (Nagar mootha) and its other similar species. Chemotaxonomic techniques including morphology, organoleptography, palynology, anatomy and phyto -chemical analysis were carried out in order to clarify the pharmaceutically important species of Cyperus that is Cyperus rotundus, Cyperus alopecuroides, Cyperus difformis and Cyperus niveus. It is concluded from this study that the genuine source of herbal drug Nagar Mootha is C. rotundus instead of other species. Such type of studies is the need of herbal industry to ensure validation process which applied in the manufacturing of herbal medicines and phyto- pharmaceuticals. This will provide the credibility in the regulation and grown of pharmaceutically important herbal medicines for the foreseeable.[...] Read More.

Abstract: Supplying emergency contraception pills through community pharmacies without the need for a doctor’s prescription is an important public health role for the pharmacy staff, as a way of reducing unwanted pregnancies and induced abortions. Therefore, we aimed to assess the Turkish pharmacy technicians’ counseling practices and attitudes regarding emergency contraception pills. A survey tool which was structured to question pharmacy technicians’ demography, professional experience, counseling practices and attitudes regarding emergency contraception pills was administered to pharmacy technicians at the end of the “pharmacy technician certification program”. The fully completed questionnaires (n=145) were further analyzed. Mean [SEM] age of the pharmacy technicians was 25.3 [0.4] years and majority (89%) of them were practicing in a community pharmacy. Despite their positive attitude towards the emergency contraception pills, pharmacy technicians were found to provide insufficient emergency contraception pill counseling to clients. We suggest that organization of continuing education programs on “reproductive and sexual health and emergency contraception” for the pharmacy technicians could help increase the quality of emergency contraception pill counseling provided by the pharmacy technicians.[...] Read More.

Abstract: Garcinia kola has been hitherto speculated as effective in the management of sickle cell disease (SCD). Investigations into the antisickling activities of both crude methanol extracts and the aqueous fractions of the leaf, seed and seed pod of G. kola were carried out using p-hydroxybenzoic acid and normal saline as positive and negative controls respectively. At the tested concentrations of 10.0, 1.0 and 0.1 mg/ml, the leaf extracts exhibited greatest antisickling activity whilst the seed pod had the least antisickling activity. However, it was observed that the activity of methanol extract of the seed pod did not differ significantly (p>0.05) from that of the positive control, p-hydroxybenzoic acid. Results for screened phytochemicals of the investigated parts revealed the presence of saponins, tannins, combined and free anthraquinones. The results infer a preliminary confirmation for the effectiveness and use of Garcinia kola in the management of SCD and its implication in drug development.[...] Read More.

Abstract: Circadian rhythms have an influence on human performance. Interleukin-6 is a cytokine which plays a role in muscle energy homeostasis during physical exercise. This study tested the effect of diurnal variation and alpha-lipoic acid, a natural thiol antioxidant, on skeletal muscle contractile properties, interleukin-6 response and oxidative damage. Male subjects (n=26) performed isokinetic exercise in different time-of-day. Next, the subjects were supplemented with alpha-lipoic acid for two weeks and the exercise tests were repeated. Blood samples were analyzed at baseline and immediately after exercise. Leg extensor muscle parameters were compared with time-of-day. Maximal work per single repetition and total work values were higher in the afternoon time, suggesting a time-of-day effect. Serum interleukin-6 levels increased in response to exercise, but were not associated with time-of-day. Alpha-lipoic acid did not have a significant effect on any of the measured parameters. Diurnal variations during exhaustive eccentric exercise seem to reflect muscle contractile work capacity. Exercise increases serum interleukin-6 levels irrespective of diurnal variation.[...] Read More.
Keywords: Diurnal variation, lipoic acid, interleukin-6, muscle performance.

Abstract: The study investigated the effect of Cucurbita pepo seeds on haematological and biochemical parameters on Wistar albino rats. The rats were maintained on diets composed of different concentrations of pulverized seeds of C. pepo. Blood samples and organs investigations were carried out using standard laboratory tests. The result revealed that C. pepo seeds significantly affected these parameters with beneficial effects on the vital organs and blood. The concentrations of the platelets, white blood cells and eosinophil were increased, while it reduced the concentrations of the neutrophils, packed cell volume and lymphocytes. It also significantly increased mean weights of the liver and the kidneys as evidenced by the statistically significant increase in total protein values of these organs. The doses significantly reduced the plasma levels of AST and ALT in these organs (p[...] Read More.

Abstract: Resistin belongs to a family of cysteine- rich secreted polypeptides produced by monocy-tes/macrophages. It is also regarded as a novel adipokine that has been suggested to play a role in the development of insulin resistance and obesity. In humans, inflammatory cells seem to be the major source of resistin. Resistin has been suggested to be an independent risk factor involved in the pathogenesis of numerous disorders. Cardiovascular complications account for significant morbidity and mortality. Moreover, resistin has been demonstrated to play a pivotal role in the pathogenesis of various vascular disorders such as atherosclerosis, hypertension, coronary artery disease and heart failure. Hence, the present review discussed the role of resistin in the pathogenesis of cardiovascular disorders.[...] Read More.
Keywords: Resistin, cardiovascular disorders, adipokine, cysteine, macrophages, monocytes.

Abstract: The aim of this study seeks to investigate the presence of steroids, triterpenes, alkaloids, saponins, tannins, anthraquinones and flavonoids compounds as the possible agent responsible for the medicinal activities of the leaf of the plant Paullinia pinnata and also to carry out phytochemical screening of the dried leaf of the plant, to extract and fractionate the leaf and finally to carry out thin layer chromatography of the different fractions. In the phytochemical investigation of the plant, the powdered leaves was tested positive for steroids, triterpenes, alkaloids, saponins, tannins, anthraquinones and flavonoids. The presence of the constituents was also found to be similar to those reported for most medicinal plants. In East Africa, the leaves are used against snake bites, rabies, mental problems, blindness and eye troubles, together with the roots, against gonorrhoea, paralysis, wounds, threatened abortion, malaria, ancylostomiasis, and to expel placenta. Roots are applied against eczema, as a tonic and as a styptic medicine.[...] Read More.
