Pollen extracts of date palm were used in tissue culture medium for banana as growth substances in comparison with growth regulators. Pollen extracts contain auxin (IBA) and tryptophan (auxin precursor). Water pollen extract (WPE) contains higher concentration of indoles compared with ethanol pollen extract (EPE). Most of treated plants showed highly growth characteristics such as shoot number,...

The importance of Amaranthus retroflexus pollen in causing respiratory allergy has been well ascertained in many countries including Iran with a high positive rate (69%) among Iranian allergic patients. The aim of the present study is to identify the allergenic properties of A. retroflexus pollen. Sixteen patients with allergy to A. retroflexus pollen were selected for the study. The antigenic ...

Corn is a major staple food, along with rice and wheat, in many parts of the world. There are several reports of hypersensitivity to maize pollen. However, cases of occupational allergic rhinitis induced by inhalation of maize pollen are very rare. We herein report the case of a 67-year-old male with occupational rhinitis caused by occupational exposure to maize pollen in a cornfield. He showed...

New approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. In the present study, In vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. The isolated bacteria identified on the basis of their biochemical properties and se...

In this paper we report results of skin prick tests (SPT) using pollen extracts on 200 patients with clinical symptoms of asthma, and results of a parallel study in which pollen was collected and classified over a period of 18 months. The patients were outpatients from the University Hospital in Kuala Lumpur, Malaysia, while the pollen grains were collected with a spore trap placed in the campu...

Phytochemicals produced by plants, including at flowers, function in protection against plant diseases, and have a long history of use against trypanosomatid infection. Floral nectar and pollen, the sole food sources for many species of insect pollinators, contain phytochemicals that have been shown to reduce trypanosomatid infection in bumble and honey bees when fed as isolated compounds. Nect...
