Abstract

The aggregated lymphoid nodules area (ALNA) in abomasum of Bactrian camels is a special immune structure discovered only in Bactrian camels in recent years (2003). The anatomy research found that there was a close relationship between degree of development, anatomical characteristics and age. To further establish the relationship between histological characteristics of this special structure and animal age, 24 Alashan Bactrian camels of the following four age groups were studied: young (1-2 years), pubertal (3-5 years), middle-aged (6-16 years) and old (17-20 years). Mucosal-associated lymphoid tissue (MALT) of ALNA in abomasum was particularly observed and analyzed by histology, histochemistry and statistical methods. The results showed that the average number of lymphoid nodules in reticular mucosal folds region of ALNA in abomasum from young group to old group was in order of 26.8, 32.7, 17.6 and 7.8, and in longitudinal mucosal folds region was 20.1, 26.0, 10.3 and 5.1. The number of lymphoid nodules in the four experimental groups first increased and then decreased with increasing age (P<0.01). In young and pubertal camels lymphoid nodules were distributed evenly on both sides of the axis of mucosal folds and mostly displa...Continue Reading
