Aflatoxins cause a variety of disorders in poultry, especially affecting the liver (aflatoxicosis). Contaminated livers may become a health risk to consumers when expended in food markets. The purpose of the present study was to detect the presence of aflatoxins in chicken livers in Lima food markets. Samples were collected in 16 markets located in various socioeconomic sectors of Lima. From every market livers were subclassified as normal and apparently suspicious. Analysis of 32 samples was conducted at the Laboratory of Biochemistry, Nutrition and Animal Feeding, Veterinary Medicine Faculty, San Marcos University. Aflatoxins were determined through the ELISA method approved by the AOAC Research Institute, using the Veratox HS (high sensitivity, 0, 1, 2, 4, and 8 ppb). Liver samples are quite complex so immunoaffinity extraction columns (NEOCOLUMN for aflatoxins, 04/08) were used. The ...

There were threesamples of Desmodium molliculum (H.B.K.) D.C. (Manayupa), which were assessed from Jaen, Cajamarca (sample El), Huanuco (sample E2) and Huancayo, Junin (sample E3), caBed it too "Runa manayupana", which is used Iike diuretic, depurative, antihemorragic, antidisenteric, anti-inflammatory of urines tracts, liver and kidneys.The results of toxic's biotest in Artemia salina Leach showed a good biology activity with values LC50: 100,427 μ,g/mL (sample El), LC50: 101,5567 μ,g/mL, LC50: 122,17 μ,g/mL (sample E2) and LC50: 93,5111 ug/mL (sample E3).About of the phitochemistry study are observed whatthree samples in study, exhibit great quantity of secondary metabolits, are appreciated flavonoids in great quantity.About of the assesses in effect anti-inflarnmatory for peroral administration, the sample E3 showed greather activity than E2 and E1 (% efficience anti-inflammatory =...

In the present investigation was determined the chemicals groups predominant in the extract etanolic of leafes of Eupatoriun gayanum Wedd (asmachilca), it was compounds fenolics and flavonoids in more cuantity. lt proved the relaxing effect of the extract etanolic of leafes of Eupatorium gayanum on aislated organs by means of Hazekamp's et al. method to (200l). The extract etanolic of leafes of asmachilca has been demonstrated the relaxing effect of easing on the smooth muscle endotraqueal, that help to explique the anti-asthmatic effect and that should to the high place contained in flavonoids, equally has been observed relaxing activity on the aorta, duodenum and ileon of rates.

At the present investigation the good conditions for the extraction of anthocyanins from purple corn cobs were investigated, by means of the employment of a complete design at random with factorial arrangement 2A3B4C4D. The factors studied were pH, solvent, time and temperature. The results showed anthocyanins between 8,404 and 47,984 mg/g of cob according to the method of differential pH. Analysis of four factors were presented.

There was studied the specie Tagetes pusilla "anisillo" " saw anise's ", which is a medicine original Asteraceae of use medical of our country, whichgrows abundant in Ayacucho's department, Tambillo's locality, between 2800 to 3000 msnm and which according to the information provided by the etnobotanic, popular medicine, anthropologic information, they indicate its uses as infusions of the air part and its essential oil, for to relieve affections of the digestive tract and for the lactic secretion, besides diuretic. In the present investigation the types detected and identified of secondary metabolits predominant in the extract etanólico of leaves of anisillo, that were fenolics compounds, flavonoids and alkaloids. The antibacterial comparatíve activity decided between the essential oil and the etanólico extract of anisillo, thinking that both showed an antibacterial significant activ...

The genotoxic potential of the aquosus extract lyophilized of fruits solanum sessiliflorum Dunal, by means of methad head anomaly of spermatozoid rnouse was evaluated. A total of 21 albino mice male of the cepa Balb/c-53 were used. Tree group experimentals with 7 animals for group: solanum sessiliflorum Dunal to dose 2000mg/kg, ciclofosfamide to dose 50 mg/kg (positive control) and saline solution 0.9 % (negative control) were established. The aquosus extract and saline solution were administed route oral and ciclofosfamide route intraperitoneal during 5 days consecutives. After 35 days of the first administration, the animals were sacrifices, epididimes extracted and prepared a solution with tripsine, coloured with eosine and procedured to extend in lamina slide (2 lamina for animal) for the later recount. The sperrnatozoids were classified following the eriterion of Wyrobex and Bruee, ...

Se ha realizado la evaluación del potencial genotóxico del extracto acuoso liofilizado de los frutos de Solanum sessiliflorum Dunal, mediante el método de anomalías de la cabeza de espermatozoides del ratón. Se utilizaron un total de 21 ratones albinos machos de la cepa Balb/c-53, distribuidos aleatoriamente en tres grupos experimentales con 7 animales por grupo: Solanum sessiliflorum Dunal a dosis de 2000 mg/Kg p.c, ciclofosfamida a dosis de 50 mg/kg p.c. (control positivo) y sohteión salina al 0.9% (control negativo). Se administró el extracto y la solución salina por vía oral y ciclofosfamida por vía intraperitoneal durante 5 días consecutivos. A los 35 días, después de la primera administración, se sacrificaron los animales, se extrajeron los epidídimos, se preparó una solución con tripsina, se coloreó con eosina y se procedió a la extensión de la muestra en lámi...
