ABSTRACT
O desenvolvimento de medicamentos tem sofrido grande avanço nos anos recentes. Diversas tecnologias têm surgido, incrementando as chances de obtenção de medicamentos mais adequados às inúmeras patologias que ainda assolam a humanidade. Tanto esses novos produtos quanto modernizações de produtos antigos sofrem, todavia, uma carga regulatória cada vez mais exigente e detalhista. Inúmeras são as normas atualmente em vigor voltadas especificamente para os produtos farmacêuticos. O trabalho do pesquisador focado no desenvolvimento de produtos farmacêuticos muda seu modus operandi, uma vez que a contemplação de tais normas passa a ser uma exigência preponderante e não mais apenas os aspectos estritamente técnicos, como outrora.
Drug product development has seen great advances in recent years. Many new techniques have appeared, increasing the chance of developing more effective medicines against the innumerable diseases that continue to assail humans. However, both these new products and also renewed forms of older products are under a heavy regulatory load, which is becoming more and more stringent and detailed. A great number of regulations specific to drug products are currently in force. Pharmaceutical researchers need to change their modus operandi, no longer taking only technical questions into consideration, but also all the regulatory aspects.

Phalotris matogrossensis (Serpentes, Colubridae) was reported as a new host for Haplometroides intercaecalis (Digenea, Plagiorchiidae). The host snake was obtained from the municipality of Anastácio, state of Mato Grosso do Sul, Brazil. One specimen of H. intercaecalis was recovered from the esophagus of the host and identified by the intercecal position of the vitellaria in the pre-acetabular region. This paper describes the second report of the occurrence of this trematode in fossorial snakes of the genus Phalotris in the state of Mato Grosso do Sul, Brazil.

1. Postsplenectomy complications have stimulated surgeons to opt for partial splenectomy as a more desirable technique for several diseases and in some cases for trauma to the spleen. 2. We studied spleen viability in 15 dogs submitted to subtotal splenectomy while maintaining the upper pole and upper splenogastric vessels. Macro-and microscopic histological studies as well as Tc99m-labeled heat-damaged erythrocyte scintigraphic analysis of splenic blood irrigation were carried out. 3. We conclude that: a) the spleen remnants develop increased cellularity of the splenic cords and lymphoid folliculi; c) the length of the epleen remnants does not change for at least 2 months after surgery
