The histological characteristics of the aggregated lymphoid nodules area in abomasum of Bactrian camels (Camelus bactrianus) of different ages.

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).

Age-related changes in the anatomical characteristics of Peyer's patches in small intestine of Bactrian camels (Camelus bactrianus).

The distribution, size, and appearance of Peyer's patches vary according to species. In order to determine the anatomical characteristics of Peyer's patches in small intestine of Bactrian camel, and age-related changes in the number of Peyer's patches, 40 Bactrian camels of the following four age groups were studied: young (0.5-2 years), pubertal (3-5 years), middle-aged (6-16 years), and old (17-20 years).

The anatomical characteristics of the aggregated lymphoid nodule area in the stomach of Bactrian camels (Camelus bactrianus) of different ages.

The aggregated lymphoid nodule area (ALNA) in the third compartment of the stomach of Chinese Alashan Bactrian camels is a recently described species-specific anatomical structure. To further establish the relationship between this structure and animal age, 40 Bactrian camels of the following four age groups were studied: young (0.5-2years); pubertal (3-5years); middle-aged (6-16years), and old (17-20years).
