Tobacco (Nicotiana tabacum L.) is an important cash crop to most farmers in Western and Central Zones of Tanzania [1]. However, the yield adversely affected by low soil fertility [2]. The nutritional requirement for provide potential yield-is high requires huge amount nitrogen (N), phosphorous (P), potassium (K) proper growth development roots [3–7].

This study reports the results of a systematic analysis of the iris vasculature in Macaca mulatta. Through the application of a variety of morphologic procedures it has been demonstrated that in rhesus monkeys, all iridial vessels, regardless of their diameter, have a similar structure. Their walls consist of (1) endothelial cells in a continuous layer resting on a basal lamina, which are provi...

The goal of this work was to increase the amount of acyclovir (ACV) in the basal epidermis, site of Herpes virus simplex infections, using microparticles as carriers. Poly(D,L-lactic-co-glycolic acid) microparticles loaded with ACV were prepared using a solvent evaporation technique. ACV distribution into porcine skin after topical application of microparticles for 6, 24 and 88 h, was determine...
