Abstract

In pulmonary function tests (PFT), the selection of prediction equation for lung diffusing capacity for carbonmonoxide (DLco), remains a problem. If a single equation is selected and used by all laboratories, the variation in percent predicted values would be large enough to cause numerous diagnostic errors. The present study involved 36 healthy adolescents (20 boys and 16 girls aged 13-19 years) with body height (157-170 cm) and body weight (38-63 Kg). Normal values were reported for lung volumes, ventilation and diffusing capacity using spirographic, helium dilution and carbon monoxide single-breath techniques. Values observed in the present study were comparable to Asians studies but lower than those of Westerns. All pulmonary function parameters were significantly higher in boys, mainly due to larger lung volume, in addition to differences in the level of physical activity and social patterns of life. Regardless to sex, indices of lung volume and diffusion increased with age, body height, and surface area, however, best correlation was observed with body height. Gender specific prediction equations were generated for lung diffusing capacity. Lung diffusion corrected for volume (DLco/VA) seemed independent to sex or body size. In conclusion, it is not appropriate to rely on prediction equations derived from western populations who had higher levels of normality for DLco. Furthermore, height was the best single predictor for lung diffusion in adolescence age group.

Abstract

This study was conducted in the Iraqi Ministry of Agriculture, Ruminant Research Station, west of Baghdad. It included447 goats born of both sexes belonging to local, Shami and their crosses. The body dimensions of kids at birth and the dam'sweight and age at birth, as well as the dependence of weaning weight on the birth weight of the kids by the use of simple linearregression equations. The results presented that coefficient of regression of most studied dimensions on the traits of maternalweight at birth and weight of the kid at birth has significant effect, except the regression of the body length at birth on both the maternal weight at birth and the kids weight at birth, which was not significant, The results showed the possibility ofdependence on the studied maternal characteristics and kids birth weight to predict the dimensions of the goat kids body atbirth.

أجريت هذه الدراسة في محطة بحوث المجترات/ وزارة الزراعة العراقية، الواقعة غرب بغداد، وشملت الدراسة على ٤٤٧ من الماعز المولودين ومن كلا الجنسين ماعز محلي وشاميه والتضريب بينها. تم دراسة أبعاد جسم المواليد عند الولادة ومدى اعتمادهم على وزن وعمر الام عند الولادة وكذلك اعتماد الوزن عند الفطام على وزن المواليد عند الولادة باستخدام معادلات الانحدار الخطي البسيط. أظهرت النتائج أن معامل الانحدار لمعظم الأبعاد المدروسة على صفات وزن الأم عند الولادة ووزن المولد عند الولادة له تاثير معنوي، باستثناء انحدار طول الجسم عند الولادة على وزن الأم عند الولادة ووزن المولد عند الولادة والتي لم تكن معنوية. النتائج اشارت الى إمكانية الاعتماد على الصفات الأمية المدروسة ووزن المواليد عند الولادة للتنبؤ بأبعاد جسم المواليد عند الولادة.
