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.

Microscopic features of the adult rabbit uterine tube during estrous cycle were studied. Twenty rabbit uterine tube were used. Rabbits were collected from local market. Sections from uterine tube infundibulum, ampulla and isthmus were prepared for histological study. Lengths and widths of various parts were obtained from the right tube. Ampulla formed the longest part, isthmus was narrowest segment and connected to the uterus. The infundibulum was with fimbrae. Epithelial liming was with few types of cells, and were; ciliated; non-ciliated secretory (peg cells) and basal cells were also demonstrated. The type of epithelial cells was pseudostratified epithelium. In the ampullary mucosa, large number of primary branches at the follicular phase was observed. Ciliation was more at the follicular phase than luteal phase. While secretory cells  during follicular was less than that at luteal phase   http://dx.doi.org/10.25130/tjps.24.2019.062

The morphology of the esophageal mucosa in long-eared owl (Asio otus) and Eurasian jay (Garrulus glandarius) has been studied. Samples with exception of the region of the esophageal tonsil were obtained from 3 adult birds of each species. They were studied by light microscopy using classical methods of morphological research. The tissue samples were fixed in 10% neutral buffered formalin and embedded in paraffin block and finally the section were cut at 5–10 µm thickness using sliding microtome and stained with hematoxylin and eosin, according to Van Gizon and Weigert and impregnated with silver nitrate according to Kelemen. The esophageal mucosa consisted of four layers: epithelium, lamina propria, muscularis mucosae, and submucosa. The epithelium was stratified squamous and better developed in the cranial part of the esophagus. The lamina propria was represented by a loose connective tissue with small amount of elastic fibers. In the long-eared owl tightly located numerous small secretory sections of the esophagus glands organised in 1–3, and in branches of large folds up to 6 layers, were found. Their short excretory ducts opened to the surface of the mucosa. The muscularis mucosae was represented by a smooth muscle tissue with bundles of cells directed longitudinally and in some areas appeared to be absent. The submucosa was well developed, and as well as lamina propria was formed by a loose connective tissue with a large number of elastic fibers. In the submucosa of the Eurasian jay secretory departments of large, not tightly located, esophageal mucous glands were found. The esophageal mucosa of this birds formed well-developed folds, which were composed of  all its layers. Their number in the long-eared owl was 20–25 and in the Eurasian jay – 5–9. The shape of folds on the transverse section is not the same: in the long-eared owl it was finger-shaped and leaf-shaped, but in the Eurasian jay it was wedge-shaped. Some large folds in the long-eared owl branched into the secondary mucosal folds. The height of folds in cranial part of the esophagus was larger than in caudal part. In both parts of the esophagus of long-eared owl  the height of the large and middle folds was larger than that in the Eurasian jay. The height of small folds in the Eurasian jay was greater than that in the long-eared owl. In both parts of the esophagus of this birds, the fold’s width at the base exceeded its width at the top. In the Eurasian jay the width of base and top of large, medium and small folds was larger than that in the long-eared owl. The esophageal mucosa was poor on immune formations. They were represented by single accumulations of diffuse lymphoid tissue, and in the Eurasian jay – even by secondary lymphoid nodules.

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

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.

1. The relative volumes of the testes and their components of 31 cockerels, 2-200 days old, were calculated and compared with the size of their increasing head appendages (Text-figs. 1a-d, 2); in addition, the effect of gestyl-administration on testes of cockerels of this age was investigated. 2. Several types of interstitial testis-cells could be distinguished morphologically and physiologically (Text-figs. 3-6 and Pl. 1); these cell-types were studied with different techniques and counted separately. 3. The main types of the interstitial cells are: (a) Lipoid cells, totally packed with lipoid globules. These cells, which are considered by many authors as fully developed Leydig cells, are not directly connected with the production of the male sex hormone; perhaps they have a secondary function in this respect, as cholesterolderivatives are stored in these cells (Pl. 1, Text-fig. 3a). (b) Secretory cells, characterized by the absence of lipoid vacuoles and the presence of numerous granular and filamentous mitochondria. These secretory cells, which produce the male sex hormone, can be divided into secretory cells A (Text-fig. 6a) without, and secretory cells B with, one large vacuole (Text-figs. 6b, 6c, 6d). 4. A considerable and partly intercellular storage of lipoids may take place at any age in the intertubular connective tissue (Text-figs. 3-4 and Pl. 1). 5. The number of the lipoid cells depends on the nutritive conditions of the animal and the development of its testes (Text-fig. 7). 6. In older cockerels most of the glandular cells lose their secretory function and pass over into lipoid storing cells. 7. Therefore we agree with Benoit, when he denies the occurrence of a ‘secretion de luxe’, but we cannot accept the presence of a ‘parenchyme de luxe’ in the testes of older cockerels.

Follicular Activity

SUMMARY A histological study was made of ovaries obtained from patients in the latter half of pregnancy; the duration of pregnancy ranged from 26 to 40 weeks. During the first 7 weeks of this period there was little evidence of follicular activity. From 33 weeks to term new Graafian follicles, rarely exceeding 4 mm in diameter, appeared in progressively increasing numbers. This may be a critical stage in follicular development when the follicle must either go on to complete maturity or suffer atresia. Luteinization of the granulosa layer occasionally occurred in these follicles but it was not accompanied by proliferation of granulosa cells; the surrounding thecal cells frequently showed no sign of luteinization and were sometimes atrophic. The factors responsible for granulosa luteinization seem not to be the same as those necessary for theca luteinization, nor are they identical with the mechanisms responsible for luteal proliferation.

The material of the authors consists of 5 cases of gonorrhea that died from accidental causes, 1 case of amputation and 3 cases. extirpation of the paraurethral course. Conclusions: the gonorrhea process is played out in the epithelium and connective tissue of the genitourinary tract and has an exudative-proliferative character. The inflammatory infiltrate consists of lymphoid cells, plasma cells, leukocytes, and eosinophils. The squamous epithelium is not an obstacle to the penetration of infection this is clearly seen when studying the process in the paraurethral passages. The penetrated deep into the gonococcus are phagocytosed by lecocytes in the surface layers of the submucosa. Metaplasia of columnar epithelium in squamous and transitional, can be in any part of the genitourinary tract and can be detected before the onset of gonorrhea. Litreitis is not necessary for gonorrhea. Prostatitis can be without vesiculitis.
