Sejak kelahirannya vespa mengeluarkan beberpa model, salah satunya vespa yang saya punya yaiutu Vespa PS, yang menjadi legenda di dunia. Mengusung desain kontak membuat vespa PS menjadi tren baru pencipta vespa, khususya kawula pemuda. Piaggio pertama kali memproduksi Vespa PS tahun 1980 dengan varian 125cc, bermesin 2 tak transmisi manual. Pada tahun 1981 Piaggio kembali meluncurkan PX series dengan kapasitas mesin 150 cc dengan memakai kode produksi P 150 X dan kemduian dilanjutkan pada tahun 1981 dengan kode P 80 X.Mendapat respon positif, Piaggio mengembangkan PX series dengan meluncurkan P200E pada tahun 1981. Sukses dengan sistem pengapian elektronik yang diterapkan pada Vespa PX yang menggunakan serie ‘E’, pada tahun 1982 Piaggio mengusung jenis Vespa PX Arcobaleno dengan Series Lusso yang pemasarannya di luar negara Italia.
though certainly not the most elegant styling, the P-series Vespas are probably the sturdiest models. In the mid-70s the basic Vespa design had been refined almost as far as it was able to go. However, changing consumer tastes, and new technologies, coupled with tightened regulations meant that Piaggio realised that it was time to totally re-design the Vespa chassis. It was such a large break from the previous style and design philosophy that many hard-core scooterists did not consider the P-series to be true Vespas, even well into the 90's. It is a debate that still continues, though the influx of new automatic scooters has tempered it and helped propel the P-series into the ranks of the classics.
AbstractThis study was carried out to determine the role of reactive nitrogen intermediates in Trypanosoma cruzi infection. In vitro, splenocytes obtained during the acute phase of infection produced elevated amounts of nitric oxide (NO) that were correlated with the resistance or susceptibility of the animals. In vivo, the levels of NO2- plus NO3- in plasma during the later phase of infection were higher in C57BL/6 mice than in BALBL/c mice. The treatment of infected C57BL/6 mice with inhibitors of NO synthase increased parasitemia and mortality. Finally, we found that the NO donor drug S-nitroso-acetyl-penicillamine is able to kill trypomastigotes in vitro in the absence of any other cells, suggesting a direct NO-mediated killing of T. cruzi.
