The importance of dexamethasone is demonstrated by its wide uses in human and veterinary medical practices [14]. Clinically, dexamethasone is administered to animals for the treatment of disease conditions such canine distemper, meningitis, necrotizing enterocolitis [5-10]. In humans, dexamethasone is most notably, used for the treatment of various complications, such as preterm complications t...

Polyamines (putrescine, spermidine, and spermine) are essential for placental growth and angiogenesis. However, little is known about polyamine synthesis in the porcine placenta during conceptus development. The present study was conducted to test the hypothesis that arginine and proline are the major sources of ornithine for placental polyamine production in pigs. Placentae, amniotic fluid, an...

Influenza virus vaccines containing from 1 to 10 mg. of virus materials per cc. concentrated and purified from infectious allantoic fluids by means of one or two cycles of differential centrifugation and inactivated by different treatments have been prepared and subjected to laboratory tests. Suitable inactivation of the virus preparations with retention of full red cell agglutinating activity ...

A study was conducted to evaluate the influence of maternal cortisol on early conceptus development in pigs (Sus scrofa). The corticosteroid synthesis inhibitor metyrapone was injected daily during days 14-19 of pregnancy, without (n = 6) and with commensurate administration of cortisol (n = 6). Blood samples were taken via an indwelling jugular catheter on days 14 and 18, and conceptuses were ...

knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. the present study aimed to evaluate the best harvesting time of h9n2 avian influenza virus (aiv) vaccine strain inoculated in specific pathogen free (spf) embryonated chicken eggs (ece)s. for this purpose, 10-5 dilution of aiv (a/chicken/iran/99/h9n2) was inoculated into 336, 11-day old ece...

The changes in genital tract morphometry, foetal dimensions, the relative volumes of fluids during gestation was evaluated Red Sokoto (Maradi) does using 28 gravid genitalia. Based on ages fetuses, each genitalia classified into one three phases namely: early, mid and late for a comparison all parameters. While both uterus placenta were significantly enlarged, (P<0.05) at gestation, other mo...

Natrix chromatography membranes combine all the advantages of chromatographic resins (specificity, selectivity, high binding capacities) and conventional membranes (high throughput, ease of operation, scalability) in a single use format. Since Natrix membranes are inherently hydrophilic they are naturally resistant to fouling, and the Crossflow device formats permit simultaneous Clarification a...
