This research was conducted to evaluate the quality of meat products at restaurants of Tabriz. For this, a total of 33 samples of ground meat mixes used for Kebab making were obtained. The samples were subjected to chemical and histological assays. Chemical analyzing was performed by means of collagen and hydroxyproline amino acid indices using colorimetric method. Moreover, histological evaluation was conducted by hematoxylin and eosin staining. Results showed that mean values of hydroxyproline and collagen were 0.0384±0.0268 and mean was 0.2993±0.0209, respectively. Besides, the presence of unauthorized bone, cartilage and lung tissues were found in 12.1 %, 18.2 % and 9.1 %, respectively. Comparison of the histological and chemical outcomes revealed that a direct difference between amount of meat and hydroxyproline ranges. Moreover, the amount of hydroxyproline was different among various tissues (i.e., hydroxyproline content was in high level in fraud samples). It was concluded that handmade meat products prepared in Tabriz were not free of inadvertent/intentional fraud; therefore organized control is essential. Manuscript profile -

The aim of this study, the investigation of the esophageal histological wall construction in camel during gestation period and after that in comparative with the esophageal histological development in other the domestic animals. For histogenesis study of esophagus in one-humped camel, 20 fetuses, around 86 days to 13 months, were chosen. Then, after the age calculating, the fetuses were stored in 10% buffer formalin and provided sections with 5 µ thickness of all the esophagus portions (cervical, thoracic and abdominal) and were stained by hematoxylin & eosin and periodic acid Schiff methods. According to the observed histological changes; developmental periods of the esophagus were divided into the three stages: the first stage (5-13 cm, 86- 110 days of pregnancy), the second stage (13-16 cm, 110-119 days of pregnancy) and the third stage (35-40 cm, 175-190 days of pregnancy). At 110 days of pregnancy, the epithelium was changed to the stratified squamous epithelium. At 119 days of pregnancy, the formation of primary stages glands tubes and neural ganglions in the esophagus were observed. At 175 days of pregnancy, in abdominal part of esophagus, thin and dispersed muscularis mucosa was observed in the connective tissue under the epithelium. The study observations revealed that the histological esophagus wall evolution, according to the gestation period in one-humped camel are less precocious than the domestic ruminants.

The traditional methods for asexual propagation of the plant faced important problems. Therefore, the seed tubers can be replaced by micro tubers produced by tissue culture. The aim of this study is search about effect of different concentrations of CaCL2 and MgSO4 in media culture In vitro in histological - cellular variations of the microtubers. In this study solid and liquid MS media were used to prepare sterilized seedlings and micro tuberization.The concentrations of 0, 1/2, 1, 3/2 and 2 times more than standard concentrations of the mentioned compounds in MS medium were used in separate induction media . Induction was done in the alternating photoperiod. In order to the developmental and anatomical studies cross sections of microtubers was prepared and studied by light microscopy.The number of cell rows, the dimensions of the cells and the starch content of the parenchymal tissues of microtuber were analyzed. the results showed significant variations in histological features of the microtubers developed in media containing different concentrations of macronutrients. CaCL2 with concentrations of 0.5 to 1 time more than standard concentration in MS medium yielded maximum number of cell rows and maximum starch granules content. However, the presence of a minimum amount of magnesium is essential for the formation of the micro tubers. But there is no statistically significant effect on cellular changes of microtubers and starch content. Manuscript profile -

Then, 24 samples specimens were preserved at 10% formalin solution and transferred to the laboratory for histological studies. Studies have shown that in one group of samples (Green Toad, Pseudepidalea (Bufo) viridis) there were toxin-producing glands. In this group, the 3-layer epithelium and below it the chromatophores were quite visible. Beneath them were large glands that produce toxins, followed by connective tissue and then striped muscles. In a group of amphibians (Marsh frog, Pelophylax (Rana) ridibunda) collected, a 4-layer epithelium was observed that divided itself into two subgroups: some with mucosal secretory glands and some without mucosal glands, but in the latter two groups, chromatophores, connective tissue, striped muscles and cartilage were seen. Another group of amphibians found that the epithelium was three-layered but had no venom-producing glands or no mucosal glands, but two features were seen in histological observations, such as some with cartilage and some without cartilage. The results of histological studies showed that in addition to morphological, morphological and genetic studies, histological studies can be used to identify of Anura. These differences indicate the possibility of polymorphism in the Marsh frog species. Manuscript profile -

Intestinal structures in these fishes are different from diet of carnivorous. Recognition histology of the intestine in this fish can help to feed and nutritional requirement for the development of upbringing of this fish.In this study, 10 Shirbot with average weight 354.25±60.52 g and mean length of 36.25±4.16cm was chosen and after the easy drawing, the intestine are removed and the section of paraffin embedding and stained by routine histological was done about it. With Dino lite lenses and Dino capture software various parts was measured and then data were analyzedwith SPSS software and with p Manuscript profile
