RESUMEN
Este trabajo documenta el primer registro de anomalías cromáticas en el pecarí de collar (Pecari tajacu) y el tercero en el mapache (Procyon lotor) para México. Los hallazgos se realizaron durante el monitoreo realizado entre el 2009 y el 2021, utilizando cámaras-trampa, principalmente en la ecorregión de la Sierra Madre del Sur del estado de Guerrero, México. Procyon lotor fue registrado entre el 5 de noviembre y el 1 de diciembre de 2019, en vegetación riparia de bosque tropical caducifolio (17°47'35"N, 98°39'59"W, 1134 m de altitud). Mientras que Pecari tajacu se registró el 7 de junio y el 22 de julio del 2021 en una brecha saca cosecha abandonada (17°38'12"N, 100°40'50"W; 1532 m de altitud).
This paper documents the first record of chromatic anomalies in Collared Peccary (Pecari tajacu) and the third in the Raccoon (Procyon lotor) for Mexico. The findings were made during monitoring conducted between 2009 and 2021, using camera traps, primarily in the Sierra Madre del Sur ecoregion of the state of Guerrero, Mexico. Procyon lotor was recorded between November 5th and December 1st, 2019, in riparian vegetation of a deciduous tropical forest (17°47'35"N, 98°39'59"W, 1134 m altitude). Meanwhile, Pecari tajacu was recorded on June 7th and July 22nd, 2021, in an abandoned crop clearing (17°38'12"N, 100°40'50"W; 1532 m altitude).
RESUMEN
Resumen Las coloraciones anormales en aves son raras y poco documentadas. Se han relacionado a problemas congénitos y con factores externos, consideradas como un indicador ambiental que da evidencia y pistas sobre la calidad de las poblaciones a nivel genético. Identificamos un caso de anormalidad pigmentaria en un trogón elegante (Trogon elegans (Gould, 1834)) en el Área Natural Protegida Reserva de la Biosfera El Cielo, México. Determinamos el tipo como dilución pastel, en esta mutación ambas melaninas se ven fuertemente afectadas, donde carecía de melanina, pero mantuvo los carotenoides con el rojo de las plumas ventrales. Discutimos posibles explicaciones para esta coloración anormal y asumimos que fueron alteraciones genéticas o de desarrollo del individuo las que causaron el decolorado del plumaje.
Abstract The bird abnormal colorations are rare and poorly documented. They had been related to congenital problems and external factors, considered as an ambiental indicator that gives evidence and clues about the quality of the populations at a genetic level. We identified a pigmentary abnormalitycase on a Elegant Trogon (Trogon elegans (Gould, 1834)) in the natural protected area "Reserva de la Biosfera El Cielo", Mexico. We determined the type as pastel dilution, on this mutation both melanin are greatly affected, where it lacked melanin, but it kept the carotenoids with the rd color on the ventral feathers. We discuss posible explanations for this abnormal coloration and asume that it was due to genetic or developmental alterations of the individual that caused the bleaching of the plumage.
RESUMEN
As a unique innovative dosage form of China, traditional Chinese medicine injection (TCMI) has the characteristics of high bioavailability and rapid onset, therefore it plays an important role in the treatment of acute and severe diseases. However, more adverse reactions of TCMI have been reported along with its wide application in clinic and the increasing varieties. In the clinical application process, there are obvious color differences between the same kind of injection, which has attracted the attention of researchers whether this phenomenon is related to safety. The safety issue of TCMI has become more and more prominent, which greatly limits the application and development of TCMI. In this article, we summarized the reasons that influenced the chromatic aberration and safety of the TCMI, and analyzed the relationships between them. It is expected to provide some new ideas for exploring the reasons that affect the safety of TCMI and improving TCMI quality by technical improvement. This article provided a reference for rational application of TCMI in clinical practice.
