  • A convenient spectrophotometric method was examined for the determination of amantadine sulfate (AMTS) which has no UV-VIS chromopohores. AMTS was ion-paired quantitatively with methyl orange (MO) at $70^{\circ}C$ for 30 min. The ion-paired complex was extracted with dichloromethane and the absorbance was measured at 421.5 nm. A linear relationship was observed in the range of $2.5{\times}10^{-7}\;M$ to $3.75{\times}10^{-6}\;M$ and the correlation coefficient was 0.999 (n=3). This assay method was applied to the quantification of AMTS in commercial tablet form with good recovery and high precision.

  • Nitrocellulose [NC]-Poly(vinylamine) [PVAm] blended membranes with the change of amino group contents were prepared. The sorption and permeation of a mono-sulfonic acid dye, Orange II, in the membranes were investigated by the steady-state permeation method at $50^{\circ}C$ and pH 2.2. The results were discussed in the framework of dual sorption and diffusion theory. It was found that thesorption isotherms comprise a partition and two Langmuir type adsorption having similar binding constants. One of the latter sorption modes is due to unknown adsorption sites in NC and the other is due to the amino groups in PVAm. Apparent diffusion coefficients for collective P and L dye species, $D_P\; and D_L$, were obtained. Interpretation of $D_P$ values leads to two modes of partitions; one is such that dye is immobilized in NC and the other is the dissolution of the dye into the internal water phase.

  • SS cream and its revised formula, CJ-4001 is topical Chinese herbal drugs for premature ejaculation. To evaluate the genotoxic potentials of these drugs, micronucleus test using Acridine orange (AO) staining method was performed. Acridine orange (AO) staining is adopted in OECD guideline 474 and widely used in micronucleus test. In dose range finding study, no mouse was dead at 2000 mg/kg using single treatment subcutaneously. Therefore, 3 dose levels were chosen at 500, 1000, 2000 mg/kg. (omitted)

  • Sensitive and safe method for visualization of DNA in agarose gels using visible dye is described. To improve the sensitivity, we studied a counterion-dye staining method using methyl orange as a counterion-dye which contributes to reduce excessive background staining by indoine blue. Dye concentrations, PH of staining solution, mixing molar ratio of two dyes, and staining times were optimized for the counterion-dye staining. By the staining with a mixed solution of 0.005% indoine blue and 0.00165% methyl orange in 10% ethanol 0.2M sodium acetate, 8 ng of the 3 kb DNA in an agarose gel was detected within 1hr. (omitted)

  • The purpose of this study was to determine the optimum amount of four ingredients (spirulina, sugar, lemon and orange) for the preparation of spirulina madeleine using response surface methodology. Spirulina was added at a level of 3.5-6.0 g, sugar powder, at 40-60 g, while lemon and orange peel were included at a level of 0-8 g. The optimum mixing rates of spirulina powder, sugar powder, lemon and orange were 3.5, 40, 0, and 8 g for overall quality and 3.52, 54.42, 0, and 8 g for maximum score of overall organoleptic quality, respectively.

  • Mixed matrix membranes (MMMs) can be a promising alternative for the solution of dye removal from coloured effluents. Polymeric membranes are widely used due to their good film-forming ability, flexibility, separation properties, and cost. However, they have low mechanical, chemical, and thermal resistances. Moreover, the fouling of polymeric membranes is high because of their hydrophobic nature. Hence, there is an increasing interest in organic-inorganic hybrid membranes as a new-generation membrane material. It has been shown that carbon nanotubes have the potential to increase the material properties of polymers with their low density, high strength, hardness, and exceptional aspect ratio. In this work, carbon nanotubes blended MMMs were prepared and methyl orange removal efficiency of them was investigated. Compared to the bare membranes, MMMs showed not only increased hydrophilicity, water content, and pure water flux but also increased methyl orange rejection and flux recovery

  • The protective effects of BNs-3 and BNs-7, extracts of citrous orange peel, on the obesity induced by ad libitum feeding a cholesterol-containing diet to rats were investigated. The animals were fed on the diet including cholesterol (0.5%) with or without the citrous orange peel extracts BNs-3 (5%) and/or BNs-7 (0.1%) for 8 weeks. The ad libitum feeding a diet containing cholesterol to rats from 6 weeks of age increased the body weight gain compared with that of rats fed on a normal diet. Such an increase in body weights was markedly attenuated by the addition of BNs-3 or BNs-7 to the diet. Especially, a combinational feeding on BNs-3 and BNs-7 significantly reduced the body weight gain below that of normal diet-fed animals. Interestingly, the weights of abdominal adipose tis-sues surrounding epididymides were greatly reduced by the citrous orange peel extracts, in parallel with the decrease in body weights. In addition, blood concentrations of lipids including cholesterol were also lowered by the combinational treatment with BNs-3 and BNs-7. Taken together, it is suggested that the obesity and overweight produced by unrestricted overfeeding on diet with cholesterol may be partially due to the accumulation of abdominal adipose tissues, around the epididymides in rats, and that citrous orange peel extracts might exert antiobese activities by reducing the adipose tis-sues as well as blood lipid concentrations.

  • Beverages based on fruit juices are among the most popular commercially available drinks. There is an ever-increasing demand for these juices in the market. Orange juice is one of the most common as well as most favorite flavor. The fruit processing industries have a tremendous responsibility of quality control. For quality evaluation estimation of various components of the juice is necessary. Sucrose, glucose, fructose, citric acid and malic acid are the prime components of orange juice. Little information is available on analysis of orange juice. However, conventional and general wet chemistry procedures are currently being used which are no longer desired by the industry owing to the time involved, labor input and harmful chemicals required for each analysis. Need to replace these techniques with new, highly specific and automated sophisticated techniques viz. HPLC and spectroscopy has been realized since long time. Potential of Near Infrared Spectroscopy in quantitative analysis of different components of food samples has also been well established. A rapid, non-destructive and accurate technique based on Near Infrared Spectroscopy for determination of sugars and organic acids in orange juice will be highly useful. The current study is an investigation into the potential of Near Infrared Diffuse Reflectance Spectroscopy for rapid quantitative analysis of sucrose, glucose, fructose citric acid and malic acid in orange juice. All the Near Infrared measurements were peformed on a dispersive NIR spectrophotometer (ELICO 153) in diffuse reflectance mode. The spectral region from 1100 to 2500nm has been explored. The calibration has been performed on synthetic samples that are mixtures of sucrose, glucose, fructose, citric acid and malic acid in different concentration ranges typically encountered real orange juice. These synthetic samples are therefore considered to be representatives of natural juices. All the Near Infrared spectra of synthetic samples were subjected to mathematical analysis using Partial Least Square (PLS) algorithm. After the validation, calibration was applied to commercially available real samples and freshly squeezed natural juice samples. The actual concentrations were compared with those predicted from calibration curve. A good correlation is obtained between actual and predicted values as indicated by correlation coefficient ($R^2$) value, which is close to unity, showing the feasibility of the technique.

  • 썩덩나무노린재는 두과작물에서 과실에 이르기까지 다양한 작물을 가해하는 대표적인 다식성 노린재의 일종이다. 과실이 썩덩나무노린재의 발육에 필요한 영양원인지 불필요한 영양원인지 아직도 분명하지 않다. 그리하여 사과와 오렌지의 단독먹이 및 콩-땅콩과의 먹이조합에 따른 썩덩나무노린재의 발육, 사망률 및 증식률을 평가하였다. 썩덩나무노린재 약충은 사과단독먹이에서만 높은 사망률로 성충으로 발육하지 못하였다. 물만 제공한 것은 3령으로 발육하지 못하였고, 사과단독먹이에서 4령으로 발육하지 못하였다. 하지만 오렌지단독먹이에서 14%가 성충으로 우화하였으나, 약충의 발육기간이 약 74일로 가장 길었다. 콩-땅콩과 조합한 먹이에서 노린재의 사망률은 38~44%를 나타내었다. 총 산란수는 169~190개 였으며, 부화률은 81~83%이었다. 따라서 사과는 썩덩나무노린재의 발육에 불완전한 먹이 이었으나, 오렌지는 발육이 지연되기는 하였으나 이루지는 것으로 평가되었다.
