Because both bradykinin and tachykinins have a potent inflammatory action, these molecules may be involved in the late allergic response. The role of these molecules in airway microvascular permeability during the late allergic response in sensitized guinea-pigs was investigated. Three weeks after ovalbumin sensitization, the animals were pretreated with bradykinin B2 receptor antagonist HOE 14...

Nerve growth factor (NGF) determines sympathetic innervation of target tissues, and NGF levels are increased in young spontaneously hypertensive rats (SHR). Angiotensin can affect NGF levels, and the persistent reduction in blood pressure after brief angiotensin-converting enzyme inhibition in young SHR may involve long-term changes in NGF and sympathetic innervation. We measured the relative a...

The hoes are widely used in the farms and home gardens in the United States. Many existing hoes are not ergonomically designed because they require a lot of back bending and wrist bending during use. Back bending often causes lower back injuries, and wrist bending often causes carpal tunnel syndrome. It can be very expensive to cure these injuries. The objective of this project is to reduce bac...

The loss of soil particles due to erosion is one the main problems current agriculture. However, tillage may also contribute undesirable transport particles. It note that effects particular working elements used on implements for have not been described in a sufficient way. To determine translocation particles, measurements were done Central Bohemian region. Two basic machines measureme...

The authors have developed a row-crop cultivator equipped with ridge former, which allows performing high-quality operations of row crop cultivation in one pass. inter is carried out cultivator, on each section two formers are mounted so that their flat discs directed towards the plants at an acute angle, and extreme edges wings V-shaped sweeps located lower base soil ridge. When moves, loosen ...
