Antioxidant properties, chemical composition and nutritional value of Terfezia boudieri (Chatin) from Turkey.

Our objectives were to investigate the chemical composition, nutritive value and antioxidant activity potentials of Terfezia boudieri Chatin collected from different areas from Southeast of Turkey. The amounts of energy, protein, fat, carbohydrate, crude fibre, moisture and ash were 34.00-65.00 (kcal/100 g), 1.40-2.73, 0.86-1.71, 4.84-11.60, 80.86-90.33 (g/100 g, f.w.) and 1.02-1.98 g/100 g dry mass, respectively. Fatty acids and amino acids analyses revealed that linoleic acid and glutamic acid were, respectively the most abundant. Among the essential amino acids leucine was the highest amount and this was followed by threonine. Magnesium was the most abundant element with a concentration value of 182.30 mg/100 g dry mass. T. boudieri exhibited excellent antioxidant activity when compared with standard compounds. In total antioxidant and chelating effect on ferrous ions activity T. boudieri showed the highest activity against the standards. Additionally, at all studied tests antioxidant activity of the mushroom increased with increasing concentration. The total phenolic content of T. boudieri was found as 8.45 mg/g.

Prevalence of immediate hypersensitivity reactions to cow's milk in infants based on skin prick test and questionnaire.

OBJECTIVE: Cow's milk (CM) hypersensitivity is one of the most frequent hypersensitivities in infants. The objective of our study was to investigate the prevalence of immediate hypersensitivity to CM based on skin prick test results and to evaluate associated allergic conditions ascertained by questionnaire in infants living in Istanbul. METHODS: All infants born between June 2001 and May 2002 were recalled to the hospital according to their dates of birth, and 1015 infants aged between 8-18 months were included in the study. An interview was conducted with each mother and a questionnaire requesting data on cow's milk hypersensitivity and other allergic diseases was completed during this interview. A cow's milk skin prick test (SPT) was applied to all infants. An open CM challenge test was then carried out on infants with a positive SPT to CM. RESULTS: Among the 1015 infants who underwent SPT, six (0.59 %) demonstrated immediate hyper-sensitivity to the CM allergen and three (0.29 %) developed a positive response to the CM challenge test. The results of the questionnaire revealed that 112 (11.0 %) of the infants had family history of allergic diseases, 96 infants (9.5 %) had a positive history of recurrent wheezing, and 166 (16.4 %) had a history of skin rash resembling atopic dermatitis. CONCLUSIONS: Our results suggest that CM hyper-sensitivity, with its low prevalence, might not be a serious health concern in Turkish infants.

Prevalence of egg sensitization in Turkish infants based on skin prick test.

AIM: Egg allergy is one of the most frequent allergies in infants. The aim of this study was to determine the frequency of sensitization to egg in infants based on skin prick test results and to evaluate associated allergic conditions by questionnaire. METHODS: All infants born between June 2001 and May 2002 were recalled to the hospital according to their dates of birth, and 1015 infants aged between 8-18 months were included in the study. An interview was conducted with each mother and a questionnaire requesting data on food allergy and other allergic diseases was completed during this interview. An egg skin prick test (whole egg) was applied to all infants. RESULTS: Positive skin prick test results were recorded in 19 infants (1.87 %). There was no difference between the prick test-positive and -negative groups with respect to any of the demographic characteristics investigated (gender, age, birth weight, egg consumption, age of introduction of egg and other solids, breastfeeding). No significant association was demonstrated between sensitization to egg and family history of allergy. Moreover, there was no association between sensitization to egg and occurrence of atopic dermatitis, recurrent wheezing, gastrointestinal symptoms and doctor diagnosis of asthma. CONCLUSION: The prevalence of egg sensitization based on skin prick test results has been found as 1.87 % among Turkish infants in Istanbul. However, no significant relationship was found between allergic sensitization to egg and occurrence of allergic diseases in this study population.
