Bovine pregnancy-associated glycoproteins (boPAG) can be classified into two main subfamilies: the boPAG–1 and the boPAG–2 groups. RIA systems allow quantifying boPAG-1 molecules in pregnant cattle. Concerning boPAG-2, as no radioimmunoassay was developed, its quantification in peripheral blood of pregnant cows remains to be investigated. The present work aimed to develop a new heterologous RIA allowing the measurement of boPAG-2 concentrations in bovine species. A total of 77 Holstein dairy cows were used for this study. They were bled at Days 45, 90, 120, 150, 180, 210 after AI, at parturition and at Day 30 postpartum. Polyclonal antiserum against boPAG-2 (AS438) was raised in New Zealand rabbits. Due to the instability of boPAG-2 molecule, we used boPAG-1 (67 kDa) as standard (dilutions ranging from 100 to 0.8 ng/mL) and for iodination with 125-I isotope. The optimal dilution for primary AS438 was 1:1,1500. Mean concentrations of boPAG-2 increased continuously from Day 45 of pregnancy (0.78 ± 0.07 ng/mL) reaching a peak at Day 210 (32.78 ± 3.02 ng/mL). Thereafter, they decreased until parturition (7.73 ± 0.59). Lower PAG concentrations were observed at Day 30 postpartum (3.62 ± 0.31 ng/mL). In conclusion, boPAG-2 profile differed from boPAG-1. In general, concentrations of boPAG-2 reached lower values, with no dramatic increase being observed at peripartum period. Due to the lower postpartum concentrations, it is expected that this new RIA can be available for pregnancy diagnosis of cows inseminated in early postpartum, minimizing the risk of false positive concentrations due to the previous pregnancy.

A new delivery system for cutaneous administration combining the advantages of cyclodextrin inclusion complexes and those of deformable liposomes was developed, leading to a new concept: drug-incyclodextrin-in-deformable liposomes. Deformable liposomes made of soybean phosphatidylcholine (PC) or dimyristoylphosphatidylcholine (DMPC) and sodium deoxycholate as edge activator were compared to classical non-deformable liposomes. Liposomes were prepared by the film evaporation method. Betamethasone, chosen as the model drug,was encapsulated in the aqueous cavity of liposomes by the use of cyclodextrins. Cyclodextrins allowan increase in the aqueous solubility of betamethasone and thus, the encapsulation efficiency in liposome vesicles. Liposome size, deformability and encapsulation efficiency were calculated. The best results were obtained with deformable liposomes made of PC in comparison with DMPC. The stability of PC vesicles was evaluated by measuring the leakage of encapsulated calcein on the one hand and the leakage of encapsulated betamethasone on the other hand. In vitro diffusion studies were carried out on Franz type diffusion cells through polycarbonate membranes. In comparison with non-deformable liposomes, these new vesicles showed improved encapsulation efficiency, good stability and higher in vitro diffusion percentages of encapsulated drug. They are therefore promising for future use in ex vivo and in vivo experiments. [less ▲]

Miconazole is an antimycotic drug exhibiting a very poor water solubility (B1.03 mg:ml). It has been shown that cyclodextrins (CDs) are able to form inclusion complexes with miconazole and that they are able to increase its aqueous solubility. Miconazole is a weak base whose solubility depends of the pH. The purpose of this study was to investigate the influence of both CDs and different acids on the solubility of miconazole. It was found that a synergistic effect existed between CDs and different acids. The combination of hydroxypropyl-bCD (HP-bCD) (100 mM) or sulfobutylether 7-bCD (SBE7-bCD) (50 mM) and lactic acid (50 mM) allowed to dissolve more than 10 mg of miconazole per ml. NMR studies confirmed the formation of an inclusion complex miconazole–CD in an acidic medium. It was also shown by the NMR studies that the complex formed was a 1:1 complex. These results demonstrate that it is possible to develop a parenteral aqueous solution of miconazole without surfactant. [less ▲]

L'albendazole est une dérivé benzimidazole à large spectre d'activité contre les parasites helminthiques de l'homme et de l'animal. L'albendazole est très faiblement soluble dans l'eau. Il a été démontré que les cyclodextrines sont capables de former des complexes d'inclusion avec l'albendazole et d'en augmenter la solubilité. La solubilité aqueuse de l'albendazole est dépendante du pH. Le but de ce travail est d'étudier l'influence combinée des cyclodextrines et de différents acides sur la solubilité de l'albendazole. Il a été démontré qu'il existe un véritable effet synergique entre les cyclodextrines et les différents acides. L'utilisation combinée d'hydroxypropyl-b-cyclodextrine (200 mM) et d'acide lactique ou acide citrique (50 mM) permet de dissoudre plus de 1 mg/ml d'albendazole. Des études RMN ont démontré l'inclusion de l'albendazole dans la b-cyclodextrine en milieu acide. Ces résultats montrent qu'il est possible de réaliser une solution injectable et une solution orale d'albendazole grâce aux cyclodextrines. [less ▲]

This study describes a glucocapparin determination method. Based on rapeseed determination of glucosinolate (GSL), the equation of the average straight regression line is Y = 100.42X − 0.03 (R2 = 0.9998). Enzymatic hydrolysis of glucocapparin extracted from leaves and fruits of B. senegalensis, analyzed by SPME-GC-MS confirmed the presence of methylisothiocyanate as the main hydrolysis glucocapparin product. Monitoring glucocapparin contents in B. senegalensis leaves and fruits collected in 4 localities in Senegal showed differences between organs according localities and periods of harvest. Glucocapparin content was very high in dry season particularly in January and the lowest rates were recorded during the rainy period between August and November. [less ▲]
