allergy in human. A Burkard spore trap was set for seven days sampling in lebak Bulus, district in south Jakarta, while a passive
collectors with adhesive object glass were placed in Darmaga Bogor, Pasar minggu and Jagakarsa in south Jakarta. Using light
and scanning electron microscopes (sEm), pollens that were trapped and identified were acacia (Acacia auriculiformis), cogon
grass (Imperata cylindrica), coconut (Cocos nucifera), palm trees (Elaeis guineensis), maize (Zea mays), rice (Oryza sativa), and
pine (Pinus merkusii). molecular weight of protein profiles from those pollen extract using sodium dodecyl sulfate-polyacrylamide
gel electrophoresis analysis (sDs-PAgE) were dominated by 10-70 kD bands. Allergenicity in human to those pollen commercial
grasses mix extract was also included in the test to people with and without history of allergy, 69 people each, using the skin prick
test method. the seven pollen of plants trapped in indonesia are allergenic. Human sensitivity to Cogon grass and acacia pollen
are more severe than to the rest of other pollen, however, the sensitivity was most found to commercial allergens of grasses mix.
People with respiratory allergy was more sensitive than people without history of allergy. meanwhile, human sensitivity to acacia
was the same in those two groups of people. Pollen of Cogon grass and acacia are potential allergens to be used for skin prick test
in indonesia. Acacia trees are not recommended to be utilized as a shading tree since their pollen showed sensitivity reaction in
human.
Keywords: pollen, allergen, sensitivity, skin prick test.

Background: there are geographical variations with respect to allergens presence, and therefore identification of relevant allergens
in each environment is important that may have diagnostic and therapeutic implications.
method: A review of allergy skin prick tests during (April 2008 – march 2010) is performed at sultan Qaboos University Hospital,
muscat - Oman. A new panel of inhalant allergen extracts was introduced in April 2008. Pediatric and adult patients with a
diagnosis of Asthma or Allergic rhinitis (Ar) are referred by physicians for allergy skin tests. the skin prick tests were performed
according to standard method. the data were collected and analyzed using sPss. the frequencies of positive allergens sensitization
were calculated.
results: there were a total of 561 patients with asthma and allergic rhinitis. the number of patients with asthma was 103
(44.7% males and 55.3 % females). in these patients, the most common allergen sensitization is Dermatophagoides pteronyssinus
(44.7%), followed by Dermatophagoides farinae (40.8%), Cat fur (21.4%), Dog Hair (18.4%), russian thistle (14.6%), Bermuda
grass (13.6%), mosquite (11.7%), Feather mix (7.8%), 5 grasses mix (5.8%), Aspergillus mix (5.8%), Chenopodiaceous (5.8%),
Penicillium mix (4.9%), Compositae (4.9%), Date Palm (4.3%), Wheat pollen (3.9%), Cladosprium mix (3.9%), Cattle Hair & Epithelia
(1.7%). the number of patients with allergic rhinitis was 458 patients (53.9% males and 46.1 % females). in these patients, the
most common allergen sensitization is Dermatophagoides pteronyssinus (33.8%), followed by Dermatophagoides farinae (30.1%),
russian thistle (24.7%), Chenopodiaceous (16.6%), Dog Hair (14.6%), Cat fur (12.9%), mosquite (12.9%), Bermuda grass (12.4%),
Date Palm (9.8%), Compositae (7.6%), 5 grasses mix (5.5%), Feather mix (5%), Wheat pollen (4.4%), Cattle Hair & Epithelia (4.3%),
Aspergillus mix (3.3%), Cladosprium mix (2.6%), Penicillium mix (2.4%).
Conclusion: the above data identified House dust mite as the commonest allergen sensitization (which is consistent with published
data from other countries), other significant allergens are identified including date palm pollens. this will help physicians to manage
allergic asthma and Ar patients. Ultimately pollen count may be necessary to identify other significant environmental allergens in
Oman.

Background skin prick test (sPt) is a fast, safe, and efficient method to diagnose igE-mediated allergy that provides optimal
information as long as it performed and interpreted correctly. it is important that the allergens tested for should be adjusted to
the patient’s clinical condition and residential. the aim of this study is to report the result of sPt in children residing in a rural
community in Bandung, West Java, indonesia.
methods this study was a part of a nested case control study entitled, “rsV and recurrent wheezing in indonesia: 7-9 years
follow-up study with lung function studies.” this study was conducted in Department of Child Health, Hasan sadikin Hospital from
