Purpose: To examine the use of intravenous dantrolene in hospitalized patients. Materials and Methods: Medical Records of patients treated with intravenous dantrolene between 2007 and 2012 at 6 teaching hospitals were reviewed. Temperature, muscle rigidity, creatine kinase levels, and mortality were assessed in association with dantrolene use. Results: Twenty-five patients received intravenous dantrolene, 9 patients with neuroleptic malignant syndrome (NMS), 8 with hyperthermia due to sepsis, 4 with NMS and sepsis, 2 for malignant hyperthermia (MH), and 2 with hypermetabolic syndrome associated with juvenile diabetic ketoacidosis. Dantrolene was administered as a bolus of 1 - 3 mg/kg. Core temperature decreased after dantrolene administration in all groups but significant only for MH, NMS cases (Pre 102.3 ± 0.9°F vs. Post 99.5 ± 0.9°F;p Conclusion: Dantrolene was associated with reductions in temperature and rigidity in hyperthermia of diverse origins in patients admitted to Intensive care settings.

The present study was undertaken to evaluate in-vitro antioxidant and anthelmintic activity of ethanolic and aqueous extract from whole plant Sida cordifolia Linn (Malvaceae). The antioxidant activities are evaluated by various antioxidant assays like α, α-Diphenyl-β-picrylhydrazyl (DPPH) free radical scavenging, total reducing power, nitric oxide scavenging and hydrogen peroxide scavenging. The various antioxidant activities were compared to standard antioxidants such as ascorbic acid. The antioxidant activity of ethanolic extract is almost quantitatively equivalent to that of the standards used, ascorbic acid. The further anthelmintic activity of whole plant is investigated through using Indian earthworm (Pheretima posthuma) showed that it is one of the most important local medicinal plants both for ritual and ethnomedical practices. Various concentrations of ethanol and aqueous extract (10, 20, 30, 40 mg/ml) of whole plant of Sida cordifolia Linn were tested in the bioassay, which involve determination of time of paralysis of the worms. Albendazole was included as reference standard. The most activity was observed with aqueous extract as compared to standard drug. The results from the above studies indicate that plant Sida cordifolia Linn. possesses potent antioxidant and anthelmintic activity.

A procedure to make optical quality thin films of ZnxCd(1-x) Te by use of thermal evaporation of the ternary compound has been investigated. Structural and optical properties of ZnxCd(1-x)Te solid solution with x = 0.1 to 0.5 were synthesized, from the resulting ZnTe and CdTe composition used in preparation of thin films. Structural investigation indicates they have polycrystalline structure. Composition was confirmed from EDAX while SEM picture shows homogeneity in films. Plots of (αhν)2 versus (hν) yield straight line indicating direct transition occurs with optical band gap energies in the range 1.7 - 2.3 eV. It is also found with increase Zn content the band gap of the films increases. Refractive indices and extinction coefficients have been evaluated in the spectral range (200 - 2500 nm).

Sol gel spin coating method has been successfully employed for the deposition of nanocrystalline nickel oxide (NiO) thin films. The films were annealed at 400°C - 700°C for 1 h in an air and changes in the structural, morphological, electrical and optical properties were studied. The structural properties of nickel oxide films were studied by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD analysis shows that all the films are crystallized in the cubic phase and present a random orientation. Surface morphology of the nickel oxide film consists of nanocrystalline grains with uniform coverage of the substrate surface with randomly oriented morphology. The electrical conductivity showed the semiconducting nature with room temperature electrical conductivity increased from 10-4 to 10-2(Ωcm)-1 after annealing. The decrease in the band gap energy from 3.86 to 3.47 eV was observed after annealing NiO films from 400oC - 700oC. These mean that the optical quality of NiO films is improved by annealing.

Nanocrystalline copper oxide (CuO) thin films were deposited onto glass substrates by a spin coating technique using an aqueous solution of copper acetate. These films were characterized for their structural, mor-phological, optoelectronic properties by means of X-ray diffraction (XRD) scanning electron microscopy (SEM), UVspectroscopy and four probe method. The CuO films are oriented along (1 1 1) plane with the monoclinic crystal structure. These films were utilized in H2S sensors. The dependence of the H2S response on the operating temperature, H2S concentration of CuO film (annealed at 700。C) was investigated. The CuO film showed selectivity for H2S. The maximum H2S response of 25.2 % for the CuO film at gas concentra-tion of 100 ppm at operating temperature 200oC was achieved.

Spine surgery is one of the fastest growing branches of orthopedic surgery. Patients often present with a relatively high acuity and, depending on surgical approach, morbidity and mortality can be comparatively high. Among the most prevalent and most frequently fatalitybound perioperative complications are those affecting the pulmonary system; evidence of clinical or subclinical lung injury triggered by spine surgical procedures is emerging. Increasing burden of comorbidity among the patient population further increases the likelihood of adverse outcome. This review is intended to give an overview over some of the most important causes of pulmonary complications after spine surgery, their pathophysiology and possible ways to reduce harm associated with those conditions. We discuss factors surrounding surgical trauma, timing of surgery, bone marrow and debris embolization, transfusion associated lung injury, and ventilator associated lung injury.

Nanocrystalline titanium oxide thin films have been deposited by spin coating technique and then have been analyzed to test their application in NH3 gas-sensing technology. In particular, spectrophotometric and con-ductivity measurements have been performed in order to determine the optical and electrical properties of titanium oxide thin films. The structure and the morphology of such material have been investigated by X ray diffraction, Scanning microscopy, high resolution electron microscopy and selected area electron diffrac-tion. The X-ray diffraction measurements confirmed that the films grown by this technique have good crys-talline tetragonal mixed anatase and rutile phase structure The HRTEM image of TiO2 thin film showed grains of about 50-60 nm in size with aggregation of 10-15 nm crystallites. Selected area electron diffraction pattern shows that the TiO2 films exhibited tetragonal structure. The surface morphology (SEM) of the TiO2 film showed that the nanoparticles are fine The optical band gap of TiO2 film is 3.26 eV. Gas sensing proper-ties showed that TiO2 films were sensitive as well as fast in responding to NH3. A high sensitivity for ammo-nia indicates that the TiO2 films are selective for this gas.
