The experiment was carried out to investigate postnatal growth and development of crop and proventriculus of digestive tract of broiler. Total 45 (“Cobb-500”) chickens of three age groups like day 1(D1), day14 (D14), day 28 (D28) were used each group containing fifteen chickens. All birds were slaughtered after respective days then crop and proventriculus were collected. Total length, diameter and weight were determined by “slide calipers” and electronic balance. Then the samples were processed and stained with H and E stain for histological study. The length (cm), diameter (cm) and weight (gm) of crop and proventriculus were increased gradually with the age where highest at 28 and lowest at day 1. Number of mucosal folds of crop was highest at 1 and lowest at day 28. The keratinized stratified squamous epithelium of crop was thickest at day 28. Submucosa contains thin loose connective tissue. Tunica muscularis contains thick inner circular and thinner outer longitudinal smooth muscle and externally covered by adventitia. The mucosa of the proventriculus has macroscopic papillae with numerous folds and lined by simple columnar epithelium. Submucosal glands are lined by simple cuboidal to low columnar epithelium. Lamina propria contains loose connective tissue and muscularis contains scattered bundles of smooth muscle. Tunica muscularis consists of smooth muscle and externally covered by serosa.

The histology of the oesophagus and crop was studied in six species of birds: Rock Dove, Collared Dove, Rose-ringed Parakeet, Kestrel, House Sparrow and Linnet. In species, the epithelium of oesophagus and crop was a keratinised stratified squamous. The lamina propria was a loose connective tissue containing glands. Glands were either purely mucous or seromucous (mixed). In the rock dove, rose-ringed parakeet and collared dove, there were no glands either in the cervical part of oesophagus or in the crop. There were differences in the histochemistry of glands’ secretions. The muscularis mucosa was present as a thick layer of smooth muscle fibres. The tunica submucosa was a loose connective tissue containing vessels and nerves. The tunica muscularis consisted of smooth muscle and was surrounded by the tunica adventitia at the cervical part of the oesophagus and crop, and by the tunica serosa at the thoracic part of the oesophagus.

Structure and postnatal development of vagina in 21 ISA brown chickens was studied at three, 23 and 46 weeks of age. At 3 weeks of age the vagina was narrower and thicker then the uterus. The undifferentiated wall of vagina consisted of low primary mucosal folds lined by simple columnar epithelium to a pseudostratified ciliated columnar epithelium and a connective tissue layer underneath. At three weeks of age, scattered smooth muscle fibres were in the subepithelial connective tissue layer. Rapid structural changes occurred at 23 weeks of age in the adult bird, mucosal folds were narrowed and tongue-shaped. Lamina propia was devoid of glands and contained lymphocytes. Tunica muscularis was well developed at 23 and 46 weeks.DOI: http://dx.doi.org/10.3329/bvet.v28i2.10676Bangl. vet. 2011. Vol. 28, No. 2, 75 – 79

Leiomyomata are benign uterine tumors composed of smooth muscle cells and varying amounts of connective tissue. The tumor occurs in approximately 10% of all women with a greater frequency in Negro women. The reasons for growth and development of these tumors are yet unknown. Meyer and DeSnoo suggest that the tumors originate in cell rests or genitoblasts and, under estrogen stimulation, multiply to form the tumor. Witherspoon suggests an ovary-leiomyoma relationship, in which prolonged high estrogen levels are due to cystic change in the ovary secondary to pelvic inflammatory disease. Others have demonstrated development of leiomyomata in animal studies. Anderson proposes that development of the tumor stems from an undetermined connective tissue cell of either the myometrium or its blood vessels.

The objective of this investigation was to study the histological structure of the gall bladder in the common quail (Coturnix coturnix). Samples were obtained from six male and six female healthy adult common quail. Tissue sections were stained with haematoxylin and eosin. Histological results showed that the overall histology of the gall bladder of the common quail is similar to that in the chukar partridge except for the goblet cells. No significant sex-based differences were found. The gall bladder was composed of tunica mucosa, tunica muscularis and tunica serosa or tunica adventitia. The tunica mucosa was mainly lined with simple columnar epithelium which was covered by a continuous striated border of microvilli. Goblet cells were observed among the epithelial cells. The tunica mucosa formed some folds which appeared to be regularly distributed over the whole gall bladder luminal surface and were mostly isometric. Deep invaginations of the surface epithelium were observed to have grown down into the underlying mesenchyme, showing a tubular gland-like appearance. The muscularis mucosa was absent. The thin lamina propria-submucosa contained loose connective tissue which consisted of numerous diffuse lymphatic tissues, but no glands were observed. The tunica muscularis consisted of a thin circular layer of smooth muscle fibres. The loose connective tissue of the tunica serosa or adventitia was made up of adipose tissues and blood vessels. It is concluded that the histological structures of the gall bladder of the common quail are similar to those of the chukar partridge except for the presence of goblet cells among the epithelial cells of the tunica mucosa.

Current work was conducted to investigate the histological architecture of the uterine tube and uterus during the period of late pregnancy in rabbits. Twelve adult local breed rabbits were used. The samples from different parts of the uterine tube were prepared for histological study after staining with H&E, Masson’s trichrome and combine Alcian blue (pH2.5)-PAS. The pre ampulla was a narrow tube and its tunica mucosa had slightly long simple mucosal folds lined by pseudostratified columnar epithelium, the ampulla had a wide lumen and its tunica mucosa displayed several highly tall branched mucosal folds with few short simple folds while the isthmus was the narrowest region and its tunica mucosa displayed few of tall and short simple mucosal folds. The mucosa of three parts of the uterine tube was lined by pseudostratified columnar epithelium which is composed of three types of cells: mucous secretory cells, non-secretory cells and basal cells, the mucous secretory cells were the predominant type and revealed secretory activities. The lamina propria-submucosa of the uterine tube was composed of cellular connective tissue and tunica muscularis. The uterus had a very thick wall with well-recognized endometrium and myometrium, the endometrium was composed of many-branched and simple endometrial folds that were covered by multinucleated syncytial cells and simple cuboidal epithelial cells. Lamina propria was composed of loose connective tissue had scattered groups of well growing simple uterine glands that showed secretory activities. The current result showed that the uterus during the late period of pregnancy was differed from those of non-pregnant rabbits, while the uterine tube at late pregnancy has a structure that appeared prepared for the next physiological period.

Total 40 non-descriptive deshi chickens were reared in scavenging and intensive farming system (20 for each) from day 1 to 180. Gross examinations of different lymphoid organs and tissues were performed at D1, D30, D90 and D180 for both types of chickens. Tissue samples were stained with H andE stain and AmScope image measurement software was used for histomorphometry. Gross and histomorphometrical parameters of thymus, spleen and cecal tonsils gradually increased significantly (P£0.05) with the advancement of ages from D1 to D180 in both scavenging Deshi chickens (SDC) and captive Deshi chickens (CDC). Gross and histomorphometrical parameters of bursa increased up to D90 and thereafter decreased indicating the involution of bursa by D180. The gross and histomorphometrical parameters of bursa, thymus, spleen and cecal tonsils were significantly (P£0.05) higher in all age groups of CDC (except D1 chicks) as compared with SDC, owing to the different patterns of rearing system.

Normal Stage

The brood pouch of seahorses can be divided into four sequential stages based on the characteristics of the altered tissue layers during gestation: the normal stage, the embryo-carrying stage, the embryo-release stage and the repair stage. The brood pouch is composed of a folded inner pseudostratified columnar epithelium and a smooth outer stratified cuboidal epithelium. Three tissue layers between the inner and the outer epithelia are an inner loose connective tissue layer, a middle smooth muscle layer and an outer dense irregular connective tissue layer. In the normal stage, the inner loose connective tissue layer is thick and vascularised with small blood vessels; the muscle layer consists of scattered unorganised muscle fibres. In the embryo-carrying stage, the inner epithelial and inner loose connective tissue layers become distended and highly vascularised with enlarged blood vessels. In the embryo-release stage, the inner loose connective tissue layer is extensively vascularised with very large blood vessels and the smooth muscle fibres invade the outer dense irregular connective tissue layer. Structures altered during gestation gradually resume their normal condition in the repair stage. Extensive vascularisation of the brood pouch during gestation suggests an intricate paternal–embryo relationship implying other significant roles besides protective function of the pouch.

Twenty adult partridges Rhynchotus rufescens were used for morphologic and histological study. The materials destined to the morphologic study were collected and the lengths of the glandular stomach and of the muscular stomach were measured. For the histological study, fragments of the glandular stomach (gastric proventriculus, Ventriculus glandularis) and of the muscular stomach (gastric ventriculus, Ventriculus muscularis) were stained routinely with periodic acid-Schiff (PAS) and Masson’s trichrome stain. Glandular stomach is prolonged, with a fusiform format toward craniocaudalis and for the left. It presents a mean length of 3.20cm in the females and 3.65cm in the males. Gastric proventriculus is composed by several lobes and glands. The mucosa is formed by a simple cubic epithelium, which is much folded. Muscular stomach has the format of a biconvex lens, with 4.30cm and 4.35cm of mean length for the females and male, respectively. The mucosa is formed by folds lined by columnar cells and the mucus that forms the cuticula. There are crypts in the base of the folds. Closely, there is a lamina propria and a thick smooth muscle layer, which is placed according to the format of the organ. A dense portion of connective tissue constitutes the serosa, mixed by some smooth muscle cells.
