En el Banco de Germoplasma de cuyes nativos de la EEA Chumbibamba del Instituto Nacional de Innovación Agraria (Perú) se determinó el momento óptimo técnico y económico para la saca única de reproductores. Se utilizaron 320 cuyes criollos y se aplicó la metodología Fisher - Hotelling, se planteó el modelo bioeconómico de saca única de reproductores a precio constante bajo cuatro escenarios de tasas de rentabilidad. Los resultados del modelo biológico señalan que la vida productiva óptima en hembras ocurre a los 414 días de edad y en los machos a 579 días. Los valores óptimos del modelo bioeconómico para los cuyes por escenarios de rentabilidad señalan que a una tasa de descuento del 9% el periodo óptimo de saca sería a 502 días; mientras que a la tasa de descuento del 30% se reduce a 494 días.

<p><span style="font-size: medium;">Os porquinhos da Índia, também conhecidos como cobaias, além de animais de estimação têm grande importância na área de pesquisa científica. Devido ao elevado crescimento populacional, os tutores buscam métodos de esterilização para esses animais. Por este motivo, deve-se buscar um protocolo anestésico adequado. O objetivo desse estudo é avaliar os efeitos tranquilizantes e analgésicos produzidos pela neuroleptoanalgesia (NLA), coma utilização de acepromazina 0,2% na dose de 0,1 mg/kg e Fentanil 0,05% na dose de 0,005 mg/kg, ambos os fármacos foram administrados pela via intramuscular (IM). O protocolo empregado é considerado satisfatório para intervenções pouco invasivas como a Orquiectomia, além de avaliado como seguro para animais hígidos da espécie avaliada.</span></p>

A 2-year-old male guinea pig (Cavia porcellus) presented with a pea-sized swelling on his right labium. The tumour was excised and reconstructive surgery was performed using a single pedicle advancement flap, leaving the bottom of the lip intact on account of it being essential for food apprehension and manipulation. Two parallel skin incisions were made in the rostrocaudal direction for almost half the length of the head and the resulting skin flap was carefully undermined, to avoid damaging the follicles and the muscles of the whiskers. The flap was carefully sutured over the excisional defect and at 1.5 months post-surgery, only a small residual scar remains. The lips are intact, the surgical site is covered with fur and many of the whiskers have regrown. Histopathology showed the excised mass to be a grade 1 soft tissue sarcoma, most likely a malignant peripheral nerve sheath tumour.

Background: Excessive sun exposure results in increased activity of the tyrosinase enzyme and the amount of melanin in the skin which causes hyperpigmentation, a sign of premature aging. The purpose of this study was to prove that Ashitaba (Angelica keiskei) leaves extract cream 8% inhibited the increase of melanin and tyrosinase enzymes as effective as hydroquinone cream 4% in the ultraviolet B-exposed guinea pig (Cavia porcellus) skin. Methods: This study used a randomized post-test only control group design. The subjects were 36 male guinea pigs (Cavia porcellus). Subjects were divided into two groups, the hydroquinone cream 4% group and the Ashitaba leaves extract cream 8% group exposed to UVB light. Skin samples were collected 48 hours after the last exposure to measure the tyrosinase enzyme levels using the ELISA method and the amount of melanin was examined by Masson-Fontana staining. Results: The mean levels of tyrosinase in the hydroquinone cream 4% group was 19.51 ± 5.16 ng/L and the Ashitaba leaves extract cream 8% group was 23.76 ± 3.09 ng/L (p = 0.005). The mean amount of melanin in the  hydroquinone cream 4% group was 2.98 ± 2.27% and the Ashitaba leaves extract cream 8% group was 4.77 ± 3.33% (p = 0.069). Conclusion: The administration of Ashitaba (Angelica keiskei) leaves extract cream 8% inhibited the increase of melanin amount as effective as hydroquinone cream 4% and inhibited the increase of tyrosinase enzymes not as effective as hydroquinone cream 4% in the ultraviolet B-exposed guinea pig (Cavia porcellus) skin.
