Pancytopenia is classified as low blood cell count. Low levels of hemoglobin, red blood cells, white blood cells and platelets are indicative of pancytopenic state. This pancytopenic state can be treatment (drug) or disease induced. Conventional approaches available to treat pancytopenia are usually associated with many undesirable adverse effects, are costly and parenterally administered. Interest in natural products has significantly increased due to their ability to stimulate cellular components of immune system. This study is designed to investigate the hematopoietic i.e. erythropoeitic, leucopoietic and thrombopoeitic potential of water distilled flowers of Rosa damascena Mill.A combinational approach of back propagation neural network (BPNN) and genetic algorithm (GA) was proposed in the present study to optimize the extraction technology of tetramethylpyrazine (TMP) in Ligusticum wallichii Franchat. BMS-354825 solubility dmso Based on the single factor test, the orthogonal experiment design method of four factors and three levels was adopted, and the concentration of TMP was measured by high performance liquid chromatography (HPLC). Subsequently, BPNN model was trained for a predictive computational model of the performance indices via experimental data, and GA was exploited to find the optimization con ditions for extraction technology of TMP. Meanwhile, both the model and algorithm were implemented in R language. Ethanol concentration of 80%, extraction time of 1.5h, extraction temperature of 55℃ and liquid-solid ratio of 81 were derived as optimal conditions with a maximum content of TMP of 2.04 mg/g, which was confirmed with the relative error 2.63% through the validation of the experiments. This mathematical model could be used to analyze and predict the extraction technology of TMP in Ligusticum wallichii Franchat and provide a new reference for screening optimization of Chinese medicine effective parts and components.In the present study we have monitored dose dependent effects of midazolam; a benzodiazepine (CNS depressant). It is the primary drug of choice for procedural sedation, preoperative sedation, and in emergency departments. Repeated administration of this drug is reported to have abuse potential and may cause this by increasing dopaminergic neurotransmission. Since an important role of 5-hydroxy tryptamine (5-HT) is there in the pathophysiology of anxiety and addiction, administration of midazolam may involve altered 5-HT metabolism as well. Present study was designed to monitor dose-dependent effects of midazolam and select the optimum dose for further experiments. Effects of midazolam were monitored on food intake, growth rate, activities in familiar and novel environments, light dark box activity, hot plate test, forced swim test and levels of dopamine, 5-HT and their metabolites. Midazolam was administered orally (0mg/kg, 2.5mg/kg, 5.0mg/kg and 10mg/kg) and behaviors were monitored post single midazolam administrations. Rats were decapitated and whole brain samples were collected and stored at -70°C until neurochemical analysis by HPLC-EC. Findings from the present study could be implicated to increased therapeutic utility of midazolam and related benzodiazepines.Higher sodium ions in saline diluted local anesthetic may reduce the anesthetic action of the drug as injected around the nerves. However, the impact of local anesthetic dilution agents on the quality of peripheral nerve blockades has not yet been widely investigated. This study was aimed at evaluating the impact of lidocaine dilution with normal saline vs dextrose 5% on onset time of supraclavicular approach to brachial plexus block. Sixty American Society of Anesthesiologists class 1or2 patients, scheduled for elective upper extremity surgeries under sono-guided supraclavicular block were randomly assigned to receive lidocaine 2% diluted with either dextrose 5% or normal saline. At the end of lidocaine injection, sensory and motor blocks were evaluated at 5 min intervals for 30 min in the areas innervated by median, radial, ulnar and musculocutaneous nerves. link2 Block onset time and number of patients with complete sensory or motor blockade were similar in both groups. Lidocaine diluted with either normal saline or dextrose 5% produces comparable sensory and motor block onset time and success rate in ultrasound guided supraclavicular block.The objective of the current study was to compare sustained release behavior of natural and synthetic polymers in matrix tablets of lisinopril and hydrochlorothiazide combination. Guar gum was used as a hydrophilic natural polymer while Eudragit L 100-55 was used as synthetic polymer. Tablets were formulated by direct compression method using different ratios and combinations of both polymers. Various physical tests were performed. After that, in vitro drug release patterns were investigated by performing dissolution in pH 6.8 phosphate buffer. Results indicated that tablets with combination of both guar gum and Eudragit L 100-55 (formulation F10) were having the best drug release retarding behavior. All formulations followed zero order kinetics indicating the drug release was independent of the concentration. Higuchi model revealed drug release by diffusion mechanism while Korsmeyer Peppas model suggested that formulations followed the non-fickian release behavior.Genetic variation of two Ziziphus spina-christi L. (Sidr) varieties was determined by Random Amplified Polymorphic DNA (RAPD). The activity of antioxidant enzymes (peroxidase and catalase) was also determined for the two varieties (Balady and Pakistani). Moreover, the antibacterial effects of different concentrations of aqueous and ethanolic extracts of leaves of the two varieties of Ziziphus spina-christi L. were assessed against Gram-positive bacteria (Streptococcus pyogenes and Staphylococcus aureus) and Gram-negative (Klebsiella pneumoniae, Proteus mirablis and Escherichia coli). The similarity of RAPD profiles was found to be 85%. Our results suggest that Ziziphus spina-christi is an effective source of antioxidants and its leaf extract is a potential promising alternative antibacterial agent against different pathogenic bacteria.Present study is aimed to explore the rapid and reliable method of analyzing the composition of concentric layers of stones by fourier transform infrared spectroscopy with Kidney Stone Library Software (KSLS-13). Total of 69 kidney stones recovered from kidney stone patients (33 males and 36 females, mean age ranges of males and females were 10.1 to 37.3 & 15.2 to 54.4 respectively) were analyzed by fourier transform infrared spectroscopy. Composition of central, middle, peripheral layers of each kidney stone and whole stone were analyzed in the research laboratory of Institute of Biochemistry. Spectra of layers of kidney stones were collected and compared with kidney stone library software (KSLS-13). Among 69 kidney stones, 25 (36.2%) were pure stones (23.2% pure Calcium oxalate mono hydrate (COM), 10% pure carbonate apatite (CA), 3% pure magnesium ammonium phosphate (MAP)) and 44 (63.7%) mixed stones. Among 69 kidney stones, most prevalent were pure calcium oxalate stones (23.2%) and calcium oxalate mono hydrate stones mixed with carbonate apatite and ammonium hydrogen urate (AHU) (18.8%). The IR bands were compared with KSLS-13 as well as with standards. Calcium oxalate mono hydrate, carbonate apatite and uric acid were significantly increased in middle layer, but ammonium hydrogen urate and calcium oxalate dihydrate (COD) were increased in periphery. Whereas, reverse was true for magnesium ammonium phosphate in central layer. In conclusion, KSLS-13 by FTIR is found to be the most rapid and reliable method to study composition of concentric layers of kidney stones.Shenlin Fuzheng Capsule (SLFZC) is a herbal preparation used for HIV/AIDS in Guangxi, China. This study was designed to evaluate the influence of SLFZC on the pharmacokinetics of highly active antiretroviral therapy (HAART) drugs, zidovudine (3'-azido-3'-deoythymidine, AZT), 2',3'-dideoxy-3'-thiacytidine (3TC) and efavirenz (EFV). Thirty-six male SD rats were divided into three groups. Group A was given a combination of AZT, 3TC and EFV (AZT/3TC/EFV). Group B rats were given AZT/3TC/EFV simultaneously with SLFZC. Group C rats were given AZT/3TC/EFV 2h prior to SLFZC. Blood samples were collected at fixed time intervals. Plasma concentration of each antiretroviral drug was tested for calculation of pharmacokinetic parameters. There was significant difference among groups with respect to t1/2 for AZT (F=3.371, P0.05). There were no significant differences among groups in terms of Cmax, T max, AUC0-12h and CL for AZT, and t1/2, Cmax, Tmax, AUC0-12h and CL for 3TC and EFV, respectively. The results indicate that SLFZC has little impact on pharmacokinetic properties of AZT, 3TC and EFV.The current research was commenced by reaction of 1,4-benzodioxane-6-amine (1) with 4-nitrobenzenesulfonyl chloride (2) in the presence of aqueous base under dynamic pH control at 9 to yield N-(2,3-dihydro-1,4-benzodioxin-6-yl)-4-nitrobenzenesulfonamide (3) which was further reacted with a series of alkyl/aralkyl halides (4a-i) in polar aprotic solvent using catalytic amount of lithium hydride which acts as base to afford some new N-alkyl/aralkyl-N-(2,3-dihydro-1,4-benzodioxin-6-yl)-4-nitrobenzenesulfonamides (5a-i). The projected structures of all the synthesized derivatives were characterized by contemporary techniques i.e., IR, 1H-NMR and EIMS. The biofilm Inhibitory action of all synthesized molecules was carried out against Escherichia coli and Bacillus subtilis. It was inferred from their results that 5f and 5e exhibited suitable inhibitory action against the biofilms of these bacterial strains. Moreover, their cytotoxicity was also checked and it was concluded that these synthesized molecules displayed docile cytotoxicity.Diosmin is one of the most widely used phlebotonic drugs, but its poor bioavailability has restricted its usage. The aim of this study was to formulate a complex Diosmin with phospholipids (75% in PC, in 12 molar ratios) and to evaluate for solubility, drug content, X-ray diffraction (XRD), differential scanning calorimetry (DSC) and in vitro dissolution study. Further to test the bioavailability of both the complex and Alvenor⌖ in beagle dogs and compare pharmacokinetic parameters. Diosmin herbosome was found to be more soluble than both pure diosmin and Alvenor⌖. The complex contained 71.94% drug content. DSC thermograms and XRD also proved the claim of the complexation. The dissolution profile of diosmin herbosome and Alvenor⌖ in water-ethanol medium showed an increase of the dissolution for diosmin herbosome. link3 Comparison of plasma concentration and main pharmacokinetic parameters of diosmin herbosome treated and Alvenor⌖ treated dogs showed a higher Cmax for the complex with longer elimination half-life. The complexation of diosmin with phospholipids can be potentially used in enhancing the absorption and solubility, consequently increasing the bioavailability of the drug.The current research describes the antimicrobial potential of methanol, n-hexane, n-butanol, ethyl acetate and aqueous extracted samples from the leaves and fruits tissues of Capsicum annuum. Different solvent extracted samples were screened against six pathogenic microorganisms including five bacterial and one fungal specie by disc diffusion susceptibility assay using 1, 2 and 3 mg disc-1 concentrations. When analyzed statistically the data showed that different solvent extracted samples from both leaves and fruits of Capsicum annuum revealed varying degrees of antibacterial and antifungal activities. n-butanol and ethyl acetate extracted fractions from both leaves and fruits showed significant inhibition of growth against all the tested microorganisms at 1, 2 and 3 mg disc-1 concentrations. Escherichia coli were completely resistant to aqueous extracts obtained from the leaves at all the three concentrations. Klebsiella pneumonia was resistant to n-hexane extracted fraction from leaves at 1mg disc-1 concentration, however, was susceptible at 2 and 3 mg disc-1 concentrations.
