A 12-year-old female Cocker Spaniel (7.5 kg of body weight) was presented for resection of a mammary gland tumor. During surgery, the heart rate was remarkably decreased due to a second-degree type I atrioventricular block. Atropine (0.05 mg/kg) was administered to increase the heart rate. Although the heart rate was elevated, atrial bigeminy occurred and persisted until the dog fully recovered from general anesthesia. These results highlight the possibility of atrial bigeminy caused by atropine administration during anesthesia.

The receptor activator of NF-${\kappa}B$ ligand (RANKL), a member of the tumor necrosis factor ligand family, has extensive functions beyond osteoclast development. RANKL is expressed in many immune cells such as osteoblasts, osteocytes, marrow stromal cells, activated T cells, synovial cells, keratinocytes, and mammary gland epithelial cells as well as in various tissues. The ligation of RANK by RANKL promotes dendritic cells (DCs) survival through prosurvival signals and the up-regulation of the anti-apoptotic proteins Bcl-2 and Bcl-$x_L$ and plays a crucial role in DCs-mediated Th1 differentiation. Therefore, RANKL plays an important role in the regulation of DCs/T cells-mediated specific immunity. This review will briefly inform our current understanding of the role of RANKL signaling in T cells-DCs communication in the immune system.

A 9-years old spayed female Maltese was referred for the treatment of mass on the right 1^st mammary gland and acute weight bearing lameness of right hindlimb. It was diagnosed as malignant mammary tumor and cranial cruciate ligament rupture of right stifle joint. Right upper regional mastectomy followed by cranial closing wedge osteotomy (CCWO) of the right tibia were planned for the present problems. Preanesthetic work-up did not show any remarkable abnormalities. Forty-five minutes after induction of anesthesia dobutamine was administered at a rate of 5 ㎍/kg/min by constant rate infusion due to gradual decrease of blood pressure below MAP 60 mmHg during surgical procedure. Despite of the increase of dobutamine infusion rate up to 20 ㎍/kg/min, blood pressure didn't recover. At the end of regional mastectomy generalized skin redness and eyelid edema were identified. Anesthesia was stopped and CCWO procedure was cancelled. To recover from the anaphylactic reactions dexamethasone and diphenhydramine were administered. After about one hour, the patient completely recovered from hypotension and anaphylactic reactions. After 4 weeks, intradermal skin test (IDST) was performed for all the drugs used during anesthesia. Only dobutamine showed positive reaction in IDST. Therefore, dobutamine was considered as the causative agent of anaphylaxis in this patient during the anesthesia. In case of perioperative anaphylactic reaction, postoperative investigation should be performed to identify causative agent and to provide safe recommendations for future anesthetic procedure.

Caveolin-1 of the caveolin family of proteins regulates mammary gland development and has been shown to play a contradictory role in breast tumor progression. A specific anti-Caveolin-1 antibody will be useful for functional study of Caveolin-1 in different tissues. In this study, we generated a rabbit polyclonal antibody that specifically recognizes the N-terminal amino acids 50-65 of Caveolin-1. This polyclonal antibody specifically reacted with Caveolin-1 extracted from cells of different species, including human epithelial A431 cells, goat primary mammary epithelial cells and mice fibroblast NIH 3T3 cells, by Western blotting. Endogenous Caveolin-1 protein expressing in cells and normal human tissues was detected by this polyclonal antibody using immunocytofluorescent and immunohistochemical staining, respectively. Furthermore, an apparent decrease in Caveolin-1 expression in tumorous breast and colon tissues was detected by this polyclonal antibody. In conclusion, we have identified amino acids 50-65 of Caveolin-1, which contains an epitope that is specific to Caveolin-1 and is conserved in the human, goat and mouse. In future, this anti-Caveolin-1 antibody can be used to examine the progression of breast and colon cancers and to study functions of Caveolin-1 in human, goat and mouse cells.

Taxol (paclitaxel) is a powerful anti-cancer drug widely used against several types of malignant tumors. Because Taxol may exert several side effects, a variety of formulations have been developed. One of these features liposomes, regarded as one of the most promising drug carriers, biocompatible and best able to reduce drug toxicity without changing efficacy against tumor cells. Eruca sativa seed extract (SE) is considered a promising natural product from cruciferous vegetables against breast cancer, increasing chemotherapeutic and eliminating harmful side effects. The effects of Taxol-encapsulated liposomes (T) alone and in combination between Eruca sativa seed extract on nuclear factor kappa B (NF-${\kappa}B$), cyclooxygenase-2 (COX-2) and B-cell lymphoma-2 (Bcl-2) gene expression levels were investigated in rat mammary gland carcinogenesis induced by 7,12 dimethylbenz(${\alpha}$) anthracene (DMBA) using qRT-PCR. The results showed that DMBA increased NF-${\kappa}B$, COX-2 and Bcl-2 gene expression levels and lipid peroxidation (LP), while decreasing glutathione-S-transferase (GST) and superoxide dismutase (SOD) activities and total antioxidant concentration (TAC) compared to the control group. T and T-SE treatment reduced NF-${\kappa}B$, COX-2 and Bcl-2 gene expression levels and LP. Hence, T and T-SE treatment appeared to reduce inflammation and cell proliferation, while increasing apoptosis, GST and SOD activities and TAC.

Purpose: Since skin sparing mastectomy removes the mammary gland and the nipple-areolar complex preserving all mammary skin, it makes the widespread use of implants in immediate reconstruction. This article reports our experience in immediate breast reconstruction after skin sparing mastectomy by using the silicone implants in patients especially who have small to moderate sized and minimal ptotic breast. Methods: From September of 2007 to July of 2009, we performed breast reconstruction for 44 breasts of 40 women with silicone implant after mastectomy. Tumors were divided into 5 malignant types (21 IDC, 18 DCIS, 2 ILC, 2 phylloides tumor, 1 mucinous carcinoma). The implant is placed in a submuscular pocket or in a submuscularsubfascial pocket depending upon the condition of the muscles and skin flaps after mastectomy. Results: The mean age was 47 years and the average follow-up period was 11 months. Cosmetic outcome was assessed by evaluation of photographs and assessment of breast volume and shape, breast symmetry, and overall outcome. About 80% of each of these parameters was scored as good or excellent. Breast complication was developed in a total of 6 cases including 2 capsular contracture, 2 partial skin necrosis due to blue dye injection and 2 implant infection. Conclusion: The use of definitive implants in a skin sparing mastectomy is a one-stage immediate breast reconstruction with low morbidity and acceptable result. This method is considered reliable with favorable aesthetic result.

Most tumors are believed to overexpress several receptors, and small peptides targeting these receptors were developed for diagnosis and tumor therapy during past decade. Here we report that fibroadenoma can be visualized by bladder cancer specific peptide. A 9-mer bladder cancer specific peptide, which was discovered from the phage display method, was synthesized by peptide synthesizer, and additional tyrosine was conjugated at the N-terminal for radioiodination (Y-BP). Y-BP was radiolabeled with $^{131/124}I$ using Iodogen tube. The rat treated with N-butyl-N-(4-hydroxybutyl)nitrosamine for 8 weeks was allowed to grow until large size tumor was developed under axilla. The tumor model was microPET imaged sequentially using [$^{18}F$]FDG and radioiodinated $^{124}I-Y-BP$. The tumor was excised and examined by immunostaining studies. Radioiodinated $^{124}I-Y-BP$ was purified using fast protein liquid chromatography (FPLC) in > 90% radiochemical purity. The whole tumor was well visualized by [$^{18}F$]FDG with several intense focal uptake within tumor. The tumor was also clearly seen with $^{124}I-Y-BP$ at 4 h post-injection, and to our surprise the tumor uptake of $^{124}I-Y-BP$ lasted up to three days. The tumor was diagnosed histologically as a fibroadenoma derived from mammary gland. In conclusion, the bladder cancer specific peptide showed the good potential as a new radiotracer for the detection of breast fibroadenoma.
