Hydropericardium syndrome (HPS) has caused significant financial losses to the Iranian poultry industry in the past few years. Thirty-two broiler chickens with gross lesions of HPS were inspected histologically and immunohistochemically. Sampling was performed in Sabzevar, Iran. The dead and sick birds from random farms were subjected to necropsy examinations. Only four broiler chickens had no hydropericardium and the other gross findings were similar for birds. Basophilic and eosinophilic intranuclear inclusions, hemorrhages and necrosis in different organs were the primary characteristic histologic lesions. Lymphoid depletion, goblet cell hyperplasia and necrotizing enteritis were some of the findings reported in previous research. Low macrophage infiltration rate and brain lesions were other discoveries in Hematoxylin and Eosin (H&E) examination. Feulgen reaction and Cluster of Differentiation 68 (CD68) immunohistochemical staining were used for a comprehensive investigation and these techniques revealed improved histopathologic details. Feulgen staining confirmed brain lesions and some other changes in different organs. Eventually, the CD68 method revealed low macrophage presence in most organs. This study suggested that HPS might cause brain damage and the susceptibility of the Arian breed to the adenovirus needs further investigation. [ABSTRACT FROM AUTHOR]

Osteoporosis is characterized by a reduction of bone mass and destruction of bone structures, followed by high bone fragility and susceptibility. This study aims to evaluate the protective effects of pomegranate seed oil (PSO) on experimental osteoporosis in rats. Twenty-four female Wistar rats were divided into four groups: sham-operated (Sham = 6), Sham with PSO treatment (Sham+PSO = 6), ovariectomized (OVX = 6), and ovariectomized with PSO treatment (OVX+PSO = 6). OVX+PSO and Sham+PSO groups received 0.1 ml of pomegranate juice daily, and OVX and Sham groups received the same amount of paraffin oil. After eight weeks, the femur and tibia bones were removed, and the structure and metabolism of samples were assessed by histological examination. The average thickness of femoral neck trabeculae in group OVX was significantly lower than in groups Sham+PSO and Sham (p < 0.05). Regarding the number of trabeculae in the neck of the femur, a significant difference was observed between groups OVX and Sham+PSO (p < 0.05). Furthermore, trabecular separation in group OVX was significantly more than in the other three groups (p < 0.05). The trabecular separation in group OVX+PSO compared to groups Sham+PSO and Sham was significantly higher (p < 0.05). A histopathologic examination of the upper metaphysis of the tibia indicated that the number of bone trabeculae in Sham+PSO was only statistically significant in the OVX group (p = 0.018). It was also found that the average thickness of bone trabeculae in the OVX+PSO and Sham groups was significantly lower than in the Sham+SO group. The results of the present study suggest that pomegranate seed oil, having estrogenic compounds, can prevent osteoporosis in rats caused by ovariectomy. [ABSTRACT FROM AUTHOR]

Background: Aflatoxin B1 (AFB1) is one of the most important mycotoxins that contaminate food worldwide. Long- term consumption of foods contaminated with AFB1 endangers human health. Detoxification of AFB1 from food improves community health. A Specific approach to aflatoxin reduction is the use of probiotics. Kefir drink is a strong probiotic. The purpose of this study was to investigate the protective effect of kefir drink on AFB1-induced hepatic injury in adult male rats Methods: In this experimental study, 24 adult rats weighing between 150 and 200 g were used. The rats were randomly divided into 4 groups: 1) control, 2) AFB1 (50 μg/kg body weight), 3) kefir drink (10 mL/kg body weight), and 4) AFB1 + kefir drink. Aflatoxin and kefir drink received through oral gavage. At the end of the experiment (8 weeks), blood and liver samples were collected for different assays. Liver function tests and histopathological examinations were performed. Data were analyzed using 1-way analysis of variance (ANOVA) and at a significance level of <0.05. Results: Aflatoxin B1 significantly increased serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (T.Bili), as well as decreased total protein (T.P) content, compared to the control group (P < 0.05). Aflatoxin B1 induced histological changes in the liver. The results obtained from the groups treated with kefir drink with and without AFB1 were not significantly different from the control group. Histopathological changes were not found in groups treated with kefir drink with and without AFB1. Conclusion: The consumption of kefir drink reduced AFB1-induced disruptions in rats’ livers.

In this paper, the concept of K-g-frames in Hilbert pro-C*-modules is introduced, and their basic properties are examined. The conditions under which family of operators can form a K-g-frame on Hilbert pro-C*-modules are derived. Moreover g-atomic systems in Hilbert pro-C*-modules are introduced and their properties are examined. [ABSTRACT FROM AUTHOR]

A 15-year-old male terrier dog with symptoms of lethargy and severe abdominal distension was referred to the polyclinic hospital of the Ferdowsi University of Mashhad, Mashhad, Iran. In addition to numbness and abdominal distension, the dog also had anorexia and severe weakness and some skin masses were observed. Due to the enlarged abdomen, splenomegaly was diagnosed in ultrasonography. Fine needle aspiration was performed on the liver and skin mass and then, neoplastic lesions were reported based on cytology. On the necropsy, two masses were found on the liver and shoulder skin. These masses were well-encapsulated, soft and multi-lobulated. Samples taken from the liver and skin were prepared by Hematoxylin and Eosin staining and then, two different immunohistochemical markers were used to confirm the initial diagnosis. Histopathological examination of these two well-encapsulated, soft and multilobulated masses on the liver and skin showed lipid content and liposarcoma was indicated. Immunohistochemical staining using two markers, S100 and MDM2, made a definitive diagnosis and confirmed the diagnosis. [ABSTRACT FROM AUTHOR]

Alopecia areata is a chronic inflammatory disease that characterized by round or oval patches of non-scarring hair loss. From the past, Urginea maritima (white squill) was used for the treatment of hair loss in Iranian traditional medicine. We aimed the comparison of Clobetasol lotion and squill extract efficacy in treatment of alopecia areata in a randomized, double-blind clinical trial. The 42 patients were randomized into two groups. Both groups received topical squill and clobetasol lotion twice daily lotion for 12 weeks. Clinical evaluation included size of patches (using 1×1 cm2 schablone), total number of grown hair and number of terminal hair was performed every 2 weeks. Re-growth of terminal coarse hairs was evaluated using a semi-quantitative regrowth score (RGS) (0: no regrowth, 1: growth of <25%, 2: growth of 25-50%, 3: growth of 51-75%, 4: growth of >75%). There were significant differences between RGS4 in two groups after 2- and 3-month treatment (P<0.05). At the end of follow-up period, the mean hair growth rates increased significantly from 6.5 to 11.3 in squill group (P = 0.031) and it improved significantly from 10.3 to 17.9 in clobetasol group (P = 0.001). There were no significant differences between mean hair growth rates in two groups after 3-month treatment (P = 0.969). The lotion 2% of U. maritima bulbs extract showed good effect in 45% patients with patchy alopecia areata and showed moderate effect on re-growth of terminal hairs. [ABSTRACT FROM AUTHOR]

In this paper we introduce controlled *-g-frame and *-g-multipliers in Hilbert C*-modules and investigate their properties. We demonstrate that any controlled *-g-frame is equivalent to a *-g-frame and define multipliers for (C,C')-controlled *-g-frames. [ABSTRACT FROM AUTHOR]

Background: The therapeutic potential of honey is related to antioxidant activity against reactive oxygen species because it contains compounds such as polyphenols; therefore, we evaluated the potential protective effect of honey on subacute toxicity of ACR by histopathologic study on tissue lesions in rat. Methods: In Ferdowsi University of Mashhad, Mashhad, Iran, 2016, male Wistar rats were divided into 7 groups. To induce toxicity, ACR was injected (50 mg/kg for 11 d) to rats in 5 groups. In treatment groups, rats received three doses of honey 1.25, 2.5, and 5 g/kg in addition to the ACR. The two remaining groups received vitamin E (200 IU/kg) and normal saline as positive and negative control respectively. On the last day, after necropsy, tissue specimens from brain and liver were collected for histopathological studies. Results: Receiving of ACR caused tissue injuries including degeneration, necrosis, hyperemia, hemorrhage and inflammation in liver; ischemic cell change, hyperemia, hemorrhage and edema in brain tissue. Administration of honey considerably reduced tissue damages caused by ACR, particularly with dosage 5 g/kg. Conclusion: The severity of tissue lesions caused by the ACR can be reduced by honey, likely through its antioxidant activity. Increasing concentrations of honey will enhance its effectiveness.
