  • We investigated possible effect of different concentration of sugar solution and addition of antiseptic in the solution on oviposition and colony development of Bombus ignitus and B. terrestris. The rates of oviposition, colony foundation and progeny-queen production of B. ignitus were 1.2-3.0 fold higher in the 40$\%$ sugar solution than those of the 50$\%$ sugar solution. The rates of oviposition, colony foundation and progeny­queen production were 1.1-2.6 fold higher in the 40$\%$ sugar solution added in 0.3$\%$ sorbic acid as antiseptic than those of the 40$\%$ sugar solution. Further, the death rate within one month was 1.7 fold lower in the 40$\%$ sugar solution added in 0.3$\%$ sorbic acid than that of 40$\%$ sugar solution alone. In the comparison of the colony development tested using imported sugar solution, the Beehappy???, the 40$\%$ sugar solution added to antiseptic and the 40$\%$ sugar solution with­out antiseptic, the 40$\%$ sugar solution added to antiseptic was about equal to the Beehappy??? in colony development of B. terrestris. Further, the number of adults produced was 1.2-3.0 fold higher in the 40$\%$ sugar solution added to antiseptic than that of the Bee­happy???. Therefore the 40$\%$ sugar solution was more effective than the 50$\%$ sugar solution, and the 40$\%$ sugar solution added to antiseptic was the most effective in colony development and mass rearing of bumblebee.

  • In silk reeling process the carry-over cocoons must be submerged in the reeling baths filled with reeling water and left until reopening the operation. Under the detention the carry-over cocoons are apt to decay without any antiseptic treatment. Thus an useful antiseptic for the cocoons is urgently needed, and various antseptic agents have been tested for their applicability to the process. However, such an useful agent has not been developed yet. Formalin has been the only chemical used for antisepticizing carry-over cocoons, although it has many defects as the antiseptic for the cocoons. In these circumstances, recently we newly prepared an antiseptic useful for preventing the carryover cocoons from decaying. We named the new antiseptic preparation "Swi-Se-Yo." The Korean term "Swi-Se-Yo" literally means "please take a rest". Through a series of experiments with Swi-Se-Yo we obtained the following results: 1) Swi-Se-Yo, in 0.05% aqueous solution, exerted a good antiseptic effect on the boiled Cocoons submerged in the reeling baths and the effect lasted for 45 hours. The duration of the effect is about two times longer than that of Formalin. 2) The percentage of cocoon reel ability of the carry-over cocoons treated with Swi-Se-Yo was 6% higher than that of Formalin and was equal to that of flowing cold water. 3) The percentage of raw silk yield of the carry-over cocoons treated with Swi-Se-Yo was almost equal to that of Formalin and to that of flowing cold water. 4) The quality of raw silk of the carry-over cocoons treated with Swi-Se-Yo is the same as that of flowing cold water. Besides the above favourable results, Swi-Se-Yo has many advantages as an antiseptic. Chemically it is very stable. Its antimicrobial action is very strong and the spectrum is very broad. It can be available in water-soluble powder and in small bulk. And it is not harmful to human and domestic animals. Considering these profitable properties of Swi-Se-Yo, it will have a good reputation as a carry-over cocoon antiseptic. (The chemical composition and manufacturing method of Swi-Se-Yo will be published in the near future.)

  • This study was conducted to develop a reclaimer of the vehicle disinfector to be used at livestock fm. The reclaimer was mainly consisted of ball-valves, geared motors and one-chip processor, and the purpose of the system was to prevent liquid freezing as well as decrease environmental pollution of antiseptic solution. The properly spraying pressure of the vehicle disinfector was found over 1.96 MPa at 1m of the spraying range. While certain amount of the antiseptic solution remained in the injection-pipes, the spray starting time was found not making any significant effect on the remained amount of the antiseptic solution. The amounts of the antiseptic solution remained in the injection-pipes were 50 ml and 270 ml in average, respectively with and without the use of the reclaimer. The reclaimer was the most effective when the connection of the injection-pipe and sprayer line was located below the side-injection-pipe and then connected to the injection-pipe located at the bottom of vehicles.

  • The propose of this study was to evaluate the effect of the variuos antiseptic solutions and distilled water on physical properties of endodontic gutta-percha cone. The antiseptic solutions were 70% isoprophyl alcohol, 5% NaOCl and 2.5% NaOCl, as control gutta-percha cones, did not stored antiseptic solution was used. Observation periods were 1, 5, 10, 20, and 30 days. In each group,. the 15 gutta-percha cones used. A tensile strength and elongation rate measurements were performed with Instron (Instron 4501), cross - head speed was set 10 inch / min. The data were statistically analyzed and the results were as followed. 1. The tensile strength of the gutta-percha cones, stored in distilled water, were slightly decreased (p<0.05). Elongation rate was not significantly different 2. The tensile strength of the gutta-percha cones, stored in 70% isopropyl alcohol, were increased (p<0.01) except 1 day group. 3. The tensile strength of the gutta-percha cone, stored in 2.5% NaOCl, were decreased (p<.0.05). Elongation rate significantly decreased (p<0.01). 4. The tensile strength of the gutta-percha cone, stored in 5% NaOCl, were decreased (p<0.05). Elongation rate significantly decreased (p<0.01). These results showed that the changes of physical properties (tensile strength and elongation rate) in gutta-percha cone were developed after a day' when gutta-percha cone were stored at 70% isopropyl alcohol, 2.5% or 5% NaOCl. So, It was concluded that gutta-percha cone must have been used at least within one day, when they were stored at the above antiseptics. I thought that the study of substantial effects on endodontic treatment due to changes of physical properties in gutta-percha cone will be needed.

  • This experiment was carried out to determine non-destructively the hydrogen peroxide concentration of 3% antiseptic hydrogen peroxide solutions by portable near-infrared (NIR) system. Hydrogen peroxide standards were prepared ranging from 0 to 25.6 w/w% and the NIR spectra of hydrogen peroxide standard solutions were collected by using a quartz cell in 1 mm pathlength. We found the variation of absorbance band due to OH vibration of hydrogen peroxide depending on the concentration around 1400 nm in the second derivatives spectra. Partial least square regression (PLSR) and multilinear regression (MLR) were explored to develop a calibration model over the spectral range 1100-1720 nm. The model using PLSR was better than that using MLR. The calibration showed good results with a standard error of prediction (SEP) of 0.16%. In order to validate the developed calibration model, routine analyses were performed using commercial antiseptic hydrogen peroxide solutions. The hydrogen peroxide values from the NIR calibration model were compared with the values from a redox titration method. The NIR routine analyses results showed good correlation with those of the redox titration method. This study showed that the rapid and non-destructive determination of hydrogen peroxide in the antiseptic solution was successfully performed by portable NIR system without very harmful solvents.

  • This study was conducted to evaluate the effects of adding gradually increasing concentrations of turmeric extract (0, 0.1, 0.2, and 0.4%) to smoked duck meat on its chromaticity, antibiosis, and antiseptic degree against food poisoning bacteria, number of bacteria, lipid rancidity, sensory evaluation, and preference. The brightness, red color intensity and yellow color intensity changed significantly when 0.2% turmeric extract was added and the sodium nitrate concentration was reduced. Additionally, no antibiosis or antiseptic activities against food poisoning bacteria were observed in any turmeric treated samples, whereas the number of bacteria was increased in control samples compared to turmeric treated samples after 10 days of preservation. The TBARS value decreased during storage when turmeric extract concentration increased, resulting in positive sensory evaluation of its color, succulence, taste and hardness. In the preference test, the surface and meat color increased as the concentration of turmeric extracts increased. Hardness was highest at 0.2%, whereas taste was highest between 0.2 and 0.4%. The overall preference test was highest for the 0.2% extract samples. Overall, the results indicated that addition of 0.2% turmeric to smoked duck meat will lead to better nutrition, function, and overall preference.
