Introduction: Carpanenamase-producing Enterobacteriaceae (CPE) has emerged as a threat to hospitalized patients. Phenotypic test such as Modified hodge test was less sensitive and specific especially to detect blaNDM-1 which is the most predominant genotype in this region. Nucleic acid amplification technology offers improved specificity and sensitivity. Failed amplification due to the presence of inhibitors is a limitation. In this study, we tried to use previous method described by Villumseen et al with some modification using another DNA extraction kit. Methods: Ten mls of sterile whole blood taken from nearly expired blood bag from blood bank was spiked with 200 µl of 0.5mcFarland bacterial suspension from thirty-six confirmed isolates of blaNDM-1 carbapenamase-producing Klebsiella pneumoniae in an aerobic Bactec Plus and incubated until the growth was detected. The blood specimen was subjected to DNA extraction method using Macherey-Nachel, Nucleospin® Blood QuickPure followed with multiplex PCR. Results: Out of the 36 isolates, 12 isolates revealed blaNDM-1 , 9 isolates revealed blaNDM-1 and blaOXA-48, 7 isolates revealed blaNDM-1, blaVIM and blaKPC genotypes that were amplified at cycle threshold of less than 30. Another 8 isolates could not pick up any genotypes possibly due to pipetting error as all the internal control were amplified. Eight true negative gram negative isolates underwent same procedure and none amplified at a cycle threshold less than 30. Conclusion: This modified method was proved to give a high yield of CPE genotypes with the cycle threshold was set at less than or equal to 30 and able to overcome the presence of PCR inhibitors.

Kunitz-type serine protease inhibitors are a class of ubiquitous protease inhibitors, which play important roles in various life activities. The structures of such inhibitors are generally stable, and are usually characterized by the presence of one or several Kunitz domains in tandem, which are able to bind to serine proteases in a manner similar to substrate binding, thereby inhibiting enzyme activity. In terms of function, Kunitz-type serine protease inhibitors are involved in processes such as blood coagulation and fibrinolysis, tumor immunity, inflammation regulation, and resistance to bacterial and fungal infections. This article summarizes the advances of Kunitz-type serine protease inhibitors and provides new ideas for the development of novel Kunitz-type serine protease inhibitors.

Protease is responsible for many physiological functions and can act as growth factor for both malignant and normal cells in the processes of the cell division and DNA biosynthesis. There was clear relation between metastatic tumors and protease. The protease inhibitors found in the natural environment or synthesized but both have not been used in the treatment of human cancer. Currently, the protease inhibitors are studying thoroughly on their mechanism, action and application in the anti-cancer.

Each PDE have isogenies (PDE 4A, PDE 4B, PDE 4C, and PDE 4D), which had different level in tissues. A cell can contain one or more DPE type. When agent (or drug) specifically and inhibited isoenzym, it will have specific effect on proteinkinase. The PDE4 and PDE3/4 compound inhibitive drugs have effects at the same time to relax trachea and anti-inflammatory. Viagra is PDE5 selective inhibitor, more important than PDE 2-3-4 with 1000 times, PDE 1 with 80 times, PDE 6 and PDE 7 with 10 times. This agent have many in vessels and cavernosum corpus. It plays role of break dow GMPv, but it depends on NO.

A retrospective study on 181 intrauterine insemination (IUI) cases using Aromatase (Al) in superovulation protocols treated in Tu Du hospital from August to December 2003. Daily doses of Anastrozole and Letrozole were 2mg and 2,5mg, respectively. All were used single or combined with FSH for superovulation. Results: Clinical pregnancy rates of cycles using Anastrozole, Letrozole, Anastrozole+FSH, and Letrozole+FSH were 18,8%, 22,8%, 26% and 29,3% respectively. Clinical pregnancy rates were not significantly different among cycles using Anastrozole and Letrozole. Stimulation duration were longer in cycles with Anastrozole than those with Letrozole. No adverse effect was recorded during the stimulation duration
