In this study, we investigated the effect of Capsaicin (CAP) on leptin and ghrelin expression in diabetic kidneys by immunohistochemical method. The subjects were separated into 5 groups: control, sham, diabetes, CAP, and D+CAP. Streptozotocin (45 mg/kg, single dose) was administered to each rat in the diabetes and D+CAP groups intraperitoneally. Rats with blood glucose levels of200 mg/dL or higher were considered diabetic. Capsaicin (1 mg/kg) was administered subcutaneously to the rats in the CAP and D+CAP groups every day for 2 weeks. H&E, PAS, and Crossman's Triple staining were performed to examine the histology of the kidney. Leptin and ghrelin in the kidney were examined by immunohistochemical method. Histological examination revealed normal kidney tissue in the control, sham, and CAP groups. The diabetes group showed the glomerulus with scattered and narrowing of the Bowman's capsule. While leptin immunoreactivity was most intense in the diabetes group, it was observed the weakest in the CAP and D+CAP groups. While strong ghrelin immunoreactivity was seen in the control and sham groups, mild immunoreactivity was seen in the CAP group, and weak immunoreactivity was seen in the diabetes and D+CAP groups. In this study, we concluded that the application of CAP could prevent loss of appetite by reducing the leptin expression during diabetes, but could not protect ghrelin from adverse effects of diabetes.

Glucagon-like peptide-1 (GLP-1) is a polypeptide that is mainly produced by intestinal L cells and is encoded by the proglucagon gene. In this study, GLP-1 localisation was investigated in the ileum of healthy and diabetic mice by immunohistochemistry and proglucagon gene expression was assayed by reverse transcription-polymerase chain reaction.

Objectives: Ovarian torsion is an important gynaecological emergency because it causes ischemia in ovary. Our aim is to research the effects of Hypericum perforatum on p53, TNF-α, CAT, SOD, GSH, PTEN and is haPI3K/Akt/mTOR pathway in ovarian of rats with ischemia reperfusion (I/R) injury. Materials and Methods: The study included 56 adult female rats which were allocated to 7 groups; control, ischemia, ischemia 300HP, ischemia 600HP, I/R, I/R 300HP and I/R 600HP. H. perforatum was applied to ischemia 300HP, ischemia 600HP, I/R 300HP and I/R 600HP groups at the dose of 300 mg/kg or 600 mg/kg by oral gavage. Collected ovarian tissues were examined by light microscopy, biochemical and real-time PCR techniques. Results: In histological examination, the least degeneration was seen in 600HP group among other groups, apart from control group. TUNEL results showed that apoptosis level of other groups was lower than that of ischemia and I/R groups. CAT and GSH levels of I/R 600HP group increased. The highest level of PTEN and mTOR was found in the ischemia group. The Akt level was lower in I/R and I/R 300HP groups but its level was close to that of control and I/R 600HP groups. TNF-α and p53 mRNA expressions in I/R group were increased. Conclusions: The result of the study showed that H. perforatum (600 mg/kg) had an effect on tissue degeneration, CAT and GSH levels, and also TNF-α and p53 mRNA expressions levels. We suggest that H. perforatum can be considered as an agent to protect against tissues damage during ischemia reperfusion. [ABSTRACT FROM AUTHOR]

The aim of this study is to examine the goose (Anser anser) cerebellum histometric and histologically. Six female geese (aged between 10-12 months) were used in this study. After fixation in 10% formalin and following routine histologic processes, the cerebellar tissues of geese were embedded in paraffin blocks and the sections were taken from these blocks. The Kluver-Barrera nerve tissue stain technique was applied to the sections. The ocular micrometer was used for histometric measurements of folia length, diameter of purkinje cells and thicknesses of stratum granulosum and stratum moleculare. SPSS 16.0 was used for calculating mean values. It was observed histological that folia and sulci cerebelli were in the outermost layer of the cerebellum. As a result of Kluver-Barrera staining, the nerve cells in all layers appeared purple and myelin fibers appeared blue. It was found that the average length of the folia was 3397.88 ± 931.32 µm, the average thickness of molecular layer was 348.53 ± 72.92 µm, the average thickness of granular layer was 184.83 ± 48.77 µm and the average diameter of Purkinje cells was 24.23 ± 3.96 µm.

Objective(s): The aim of this study was to determine Oxytocin receptor (OTR) gene expression and localization in diabetic and non-diabetic mouse testes by RT-PCR and immunohistochemistry, respectively. Materials and Methods: In this study, 18 male BALB/c mice (8-12 weeks old) were used and divided into three groups: diabetic, sham, and control. Streptozotocin (STZ) was applied to the diabetic group and sodium citrate was administered to the sham group in the same way, however, the control group was left untouched. The testicular tissues were removed on the thirtieth day of testing; the right testis tissues were passed through a routine histologic process and sections were stained with H&E and PAS staining techniques. The avidin-biotin-peroxidase method was applied to determine OTR immunoreactivity, while the left testis tissues were used for RT-PCR. Results: It was found that the body weight had decreased in the diabetic group and the diameter of the seminiferous tubules in the said group was shorter than those of the other groups. There were no obvious differences with regard to the histologic appearance between the groups. The immunohistochemical examination showed that the OTR immunoreactivity was strong in the control and sham groups but weak in the diabetic group, and the immunoreactivity was only seen in the Leydig cells. In addition, the OTR gene expression was lower in the diabetic group than in the other groups. Conclusion: We concluded that diabetes reduces the OTR expression in the testis. It is suggested that OTR protection should be researched in diabetes for healthy reproduction and sexuality. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine the comparative differences of eggshell structure between geese and chickens during embryonic development by SEM. Goose eggs and chicken eggs were used for the study. Eggs of each species were divided into three groups: The eggs within first group were used subsequent to collection, those of second group were collected during the mid-point of incubation and those of third group were collected at the end of the incubation. The eggshells samples with dimensions of 0.5 cm2 were taken from the equatorial region of eggshells. After these samples were passed through routine process, they were examined via SEM for structural changes of eggshells and rate of elements. In the examination, there were not changes of eggshell structure between two species for days of the incubation. Eggshells thickness of each species and the rate of calcium, oxygen, nitrogen and carbon of eggshells were not statistically different among groups. It was concluded that structural changes of eggshell did not have significant effect on low yield for hatching of goose. [ABSTRACT FROM AUTHOR]

The aim of the present study was to determine the histological structure and histochemical properties of the pancreatic ducts in the goose Anser anser. Pancreatic ducts of 6 male and 6 female geese were examined. Crossman's triple stain and Masson's trichrome stain were used for histological examination, and periodic acid-Schiff, alcian blue, periodic acid-Schiff/alcian blue, and aldehyde fuchsin/alcian blue stainings were performed for histochemical examination. Dorsal and ventral pancreatic ducts were found that transfer pancreatic secretion into the duodenum of the goose, and these channels were found to have a histologically similar structure. No differences were detected between male and female geese. Duct wall was observed to consist of mucosa, muscle, and adventitial layers. In addition to dark principal, light and basal cells were observed in a simple columnar epithelium layer lining the duct. Glands, including centroacinar cells, were also detected in all layers of duct. Furthermore, lymphoid follicles were observed in the connective tissue of the mucosa. Sulfated and carboxylated mucosubstance-secreting cells were found in the duct as well as neutral, acidic, and mixed mucosubstance-secreting cells. We conclude that the results of our study may contribute to future studies. [ABSTRACT FROM AUTHOR]
