A Morphometric Study on the Skull of Donkey (Equus asinus) International Journal of Morphology
Zhu,Lei; Shi,XiaoDong; Wang,JunJie; Chen,JianGang.
The present study was carried out on a number of 16 skulls of adult male domestic donkeys. Craniometric measurements for 40 different parts of the skulls were made. All investigated features were expressed as Mean±SD. Cephalic indices and ratios were calculated by using the investigated features. The craniometric measurements and cephalic indices had been compared with those of local horses and ponies. A skull length of 443.07±53.57 mm and a maximum zygomatic width of 169.09±17.64 mm were obtained. The size of donkey skull was between those of local horses and ponies. A skull index of 38.23±0.85, a cranial index of 45.01±2.83 and a facial index of 67.80±3.79 were obtained. Cranial index and skull index were found to be close in value to that of local...

Craniometrical Studies on the Skull of Tibetan Gazelle (Procapra Picticaudata) International Journal of Morphology
Zhu,Lei.
A total of 10 skulls of Tibetan gazelle were utilized in this study. Craniometric measurements for 22 different parts of the skull were made. Skull indices and ratios were calculated. A skull index of 43.22±0.44, a cranial index of 58.37±0.80 and a facial index of 116.37±1.24 were obtained.

Histological Observation of the Stomach of the Yellow-billed Grosbeak International Journal of Morphology
Zhu,Lei; Wang,Jun Jie; Shi,Xiao Dong; Hu,Jiang; Chen,Jian Gang.
The stomachs of the yellow-billed grosbeaks were examined by means of light microscopy. The mucous membrane of the proventriculus presented many folds and sulci. The sulci were lined by simple columnar cells with basal nuclei and clear acidophilic cytoplasm. The proventriculus glands were constituted by many round or elliptical glandular lobules. The sulci and the collecting duct of compound tubular glands showed an intense positive reaction in PAS and AB stain. The gizzard was characterized by an internal abrasion-resistant lining cuticle and a thick muscular layer. The cuticle, gizzard glands and muscular layer in two sides were thicker than those in the cranial and caudal.

Histological Study of the Oesophagus and Stomach in Grey-Backed Shrike (Lanius tephronotus) International Journal of Morphology
Zhu,Lei.
The microstructure of oesophagus and stomach in grey-backed shrike were examined by means of light microscopy. The results showed that the oesophagus glands were mucous glands, the shedding glandular cells and the mucin from the oesophagus glands secreted to the lumen. The number of the glands in the thoracic part was less than that of in the cervical part. The lumens of the glands showed an intense positive periodic acid-Schiff and Alcian blue reaction. There were two types of glands in the lamina propria. The simple tubular glands were located in the superficial lamella of the lamina propria, while compound tubular glands were located in the deep lamella. The epithelium was lined by a layer of cuticle in the intermediate zone between the proventriculus...

Sexual Dimorphism in Histological Structure of Normal Rat Stomach International Journal of Morphology
Zhu,Lei; Wang,Jian Lin.
Fifty male and fifty female Spargue-Dawley rats were randomly chosen and used to study the sexual dimorphisms of stomachic histological structures. The rat stomach consisted of the nonglandular part and the glandular part. The gender differences of the nonglandular part existed in the thicknesses of the stratified squamous epithelium and the longitudinal muscle. These findings revealed that the male rat stomach may storage more foods than the female. The gastric glands occupied all the lamina propria in the glandular part. The thicknesses of the gastric glands of the female and male rat were 525.0 ± 95.9 µm and 472.0 ± 158.7 µm respectively, and the difference was very significant (p<0.01). The gastric glands could be divided to two layers in the HE...
