Field tests of three synthetic sex pheromone blends (Japanese blend: Z11–18:Ald (55 μg), Z13–18:Ald (500 μg), Z11–18:OH (120 μg) and Z13–18:OH (180 μg), Indian blend: Z11–16:Ac (50 μg) and Z13–18:Ac (500 μg) and Philippine blend: Z11–16:Ac (500 μg) and Z13–18:Ac (10 μg) based on geographic variations in sex pheromones) of the rice leaffolder moth, Cnaphalocrocis medinalis Guenée (Lepidoptera: Crambidae), were conducted at Yogyakarta (Java), and at Sempidi and Penatih (Bali), Indonesia. Only the Japanese blend attracted significant numbers of male C. medinalis, while neither the Indian nor the Philippine blend showed any attractiveness to the males. In the GC–MS analysis of a crude extract from pheromone glands of female C. medinalis collected at Sanur, Bali. Indonesia, Z11–18:Ald, Z13–18:Ald, Z11–18:OH and Z13–18:OH were detected at a ratio of 10:100:26:37, and the total amount was approximately 0.8 ng/female. Neither Z11–16: Ac nor Z13–18:Ac were detected. These results suggest that C. medinalis that respond to the Japanese blend are widely distributed from Eastern Asia through Southeast Asia.

Release Control of Drug-encapsulated Liposomes
Zhongwei Jiang,Guoming Chen,Takaaki Kawazu,Minoru Morita 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
Liposomes as a drug delivery system has been an attracting interest to many researchers. This paper concerns with the study on how to control the release rate of the inner-substances from liposomes by the ultrasonic irradiation. Two kinds of ultrasonic control methods are tested for investigation of the efficiency of the release property of the liposomes. One control method is to increase the input power by fixing its frequency at the probe resonant frequency of 28.18kHz. Another method is to adjust the input frequency around the probe resonant frequency but fixing the input power. In the experiment, instead of the drug, calcein is enclosed into the liposomes and the release effect is evaluated from the fluorescence intensity changes which is measured by a spectrofluorometer. The experiment results showed that the efficient release property can be achieved both by control of the input power and input frequency, but adjusting the input frequency around the probe resonant frequency can get higher efficient release performance than that controlled by the input power.

Purpose: To focus on the effects of the presence of mesiodens on adjacent teeth and to investigate the timing of its safe removal. Materials and Methods: Cone-beam computed tomography examinations, obtained at Okayama University Hospital over a three-year period, were inspected. Data were recorded including the number of mesiodens; associated abnormalities; and the relationship with neighboring structures. Depending on multiple factors, the risk of developing complications due to early extraction of a mesiodens was divided into three categories: high, medium, and low risk. Results: A total of 5,958 cone-beam computed tomography exams were obtained, 460 patients aged 3-85 years were diagnosed with a total of 568 mesiodens, 382 (67.3%) of which were discovered in young patients (age <10 years), and 333 (87.2%) of these were associated with abnormalities. Regarding the risk categories, 11 (1.9%) were considered to be in the high-risk, five (0.9%) in the medium-risk and 552 (97.2%) in the low-risk categories. Moreover, eight out of 11 high-risk mesiodens were extracted and no post-operative complications have been seen. Conclusion: As the results showed that no postoperative complications were seen in all the extracted cases of high- risk mesiodens, this indicates the possibility of safe extraction at an early age which could reduce related future complications.
Tectona grandis Callus Produces Antibacterial Triterpene Acids Not Detected in the Intact Plant
Marwani, Erly,Kobayashi, Akio,Kajiyama, Shin-ichiro,Fukusaki, Eiichiro,Nitoda, Teruhiko,Kanzaki, Hiroshi,Kawazu, Kazuyoshi The Korean Society of Pharmacognosy 1997 Natural Product Sciences Vol.3 No.1
Preliminary antibacterial assay data that the Tectona grandis callus extract showed more antibacterial activity against E. coli and B. subtilis than the leaf extract led the authors to isolate the following antibacterial compounds from the callus. A mixture (3) of $2{\alpha},3{\beta}-dihydroxy-olean-12-en-28-oic$ acid (3a) and $2{\alpha},3{\beta}-dihydroxy-urs-12-en-28-oic$ acid (3b) exhibited the most potent antibacterial activity against both bacteria. The other 3 compounds, in the decreasing order of the activity, were identified as $2{\alpha},3{\beta}-dihydroxy-urs-12-en-28-oic$ acid (2), betulinic acid (1), and $2{\alpha},3{\alpha}$,23-trihydroxy-urs-12-en-28-oic acid (4). The antibacterial compounds (2, 3a, 3b and 4) were not detected or occurring in small quantities in the intact tissue, while they were observed in the callus. Only the less active compound 1 was present more abundantly in intact tissues than the callus.

The ethanol extract from the leaves of Juniperus chinensis was found to be cytcrtoxic towards HeLa cells. Bioassay-guided fractionation of the EtOAc soluble faction directed by the microtitration cytotoxic assay revealed that the cytotoxic comported was deoxypodophyllotoxin. All the tumour cell lines tested (KU8112F-chronic mylogeneous leukemia, TK 10-renal carcinoma, UACC 62-melanoma and (CEM-SS-T-lymphoblastic leukemia) were found to be susceptible to deoxypodaphyllotoxin, however, floe minimum effective concentration (MEC) required to reduce the cell population by 100 percent was different between cell lines.
