  • Natural glycoproteins can induce apoptosis of tumor cells and exert anti-tumor activity by immunomodulatory functions, cytotoxic and anti-inflammation effects, and inhibition of endothelial growth factor. Given their prospects as novel agents, sources of natural antitumor glycoproteins have attracted attention and new research directions in glycoprotein biology are gradually shifting to the direction of cancer treatment and prevention of neoplastic disease. In this review, we summarize the latest findings with regard to the tumor suppressor signature of glycoproteins and underlying regulatory mechanisms.

  • Luteolin, 3', 4', 5,7-tetrahydroxyflavone, belongs to a group of naturally occurring compounds called flavonoids that are found widely in the plant kingdom. It possesses many beneficial properties including antioxidant, anti-inflammatory, anti-bacterial, anti-diabetic and anti-proliferative actions. Colorectal cancer (CRC) is a leading cause of cancer related deaths worldwide. Many signaling pathways are deregulated during the progression of colon cancer. In this review we aimed to analyze the protection offered by luteolin on colon cancer. During colon cancer genesis, luteolin known to reduce oxidative stress thereby protects the cell to undergo damage in vivo. Wnt/${\beta}$-catenin signaling, deregulated during neoplastic development, is modified by luteolin. Hence, luteolin can be considered as a potential drug to treat CRC.

  • Much has been written about the possibility that the lining of a dentigerous cyst might undergo neoplastic transformation to an ameloblastoma which is defined as mural ameloblastoma. Mural ameloblastomas are estimated to constitute 5% of all ameloblastomas. 85% of the mural ameloblastomas were associated with dentigerous cyst, all of which were observed before the age of 30. The frequency of recurrence after simple enucleation of the cyst containing this lesion is considerably lower than that for ameloblastomas in general that are treated in a similar manner. Therefore, further and more extensive surgery is not required for mural ameloblastoma. We diagnosed a cystic appearance of a 17 year-old female as dentigerous cyst and undergone marsupialization. For 2 years of period, no significant change was observed and therefore enucleation was undergone and diagnosed as ameloblastoma. We report this case with a review of related literatures.

  • A case of mammary gland adenocarcinoma is reported in a 22-year-old female Mandril (Mandrillus sphinix). The veterinarian noted a fast growing mass, which was inflammed and perforated, involving both mammary gland during the last 4 months. Supplement antibiotic and chemotherpay were unsucessful and the monkey was found dead. On necropsy, both right and left mannary gland were replaced by firm, tan, perforating neoplastic mass.

  • Sarcomatoid carcinomas are biphasic tumors which have surface epithelial changes and an underlying spindle-shaped neoplastic proliferation. A 62-year-old male with hoarseness came to our hospital for evaluation. A single smooth polypoid lesion was detected on his right true vocal fold by larnygoscope. The patient was diagnosed with vocal polyp and treated with surgical excision. Pathology report of the excised specimen was compatible with sarcomatoid carcinoma. Therefore, further surgical resection was performed to secure safety margins. We report a case of a sarcomatoid carcinoma patient who was clinically diagnosed as vocal polyp.

  • Metastasis is the primary cause of from breast cancer mortality. Cell migration and invasion play important roles in neoplastic metastasis. Matrix metalloproteinase-9 (MMP-9), which degrades the extracellular matrix (ECM), plays an important role in cancer cell invasion. NF-${\kappa}B$ is transcription factor important in the regulation of MMP-9, as the promoter of MMP-9 gene contains binding sites for NF-${\kappa}B$. Brazilin, an active component of sappan wood (Caesalpinia sappan), decreases TPA-induced MMP-9 expression and invasion in MCF-7 cells. Also, brazilin suppressed NF-${\kappa}B$ activation in TPA-treated MCF-7 cells. Taken together, we demonstrated that the inhibition of TPA-induced MMP-9 expression and cell invasion by brazilin is mediated by the suppression of the NF-${\kappa}B$ pathway in MCF-7 cells. This result suggest brazilin provide a potential therapeutic app roach for the treatment of breast cancer.

  • Pediatric onset Crohn's disease (CD) tends to have complicated behavior (stricture or penetration) than elderly onset CD at diagnosis. Considering the longer duration of the disease in pediatric patients, the accumulative chance of surgical treatment is higher than in adult onset CD patients. Possible operative indications include perianal CD, intestinal stricture or obstruction, abdominal abscess or fistula, intestinal hemorrhage, neoplastic changes and medically untreatable inflammation. Growth retardation is an operative indication only for pediatric patients. Surgery can affect a patient's clinical course, especially for pediatric CD patient who are growing physically and mentally, so the decision should be made by careful consideration of several factors. The complex and diverse clinical conditions hinder development of a systemized treatment algorithm. Therefore, timing of surgery in pediatric CD patients should be determined with individualized approach by an experienced and well organized multidisciplinary inflammatory bowel disease team. Best long-term outcomes will require proactive post-operative monitoring and therapeutic modifications according to the conditions.

  • A ten-year-old dog was presented with pancreatitis and increased hepatic enzymes. On necropsy a large firm mass was observed in the liver extending to the gall bladder. Smaller masses with similar texture were found in multiple organs including lung, stomach, pancreas, lymph nodes, omentum, and mesentery. Neoplastic cells were spindle shaped with prominent osteoid production and occasional trabeculae of woven bone. Tumor cell emboli were observed in the blood vessels and lymphatics of the omentum and stomach. Hepatic osteosarcoma with systemic metastasis is very rare and may serve to broaden the diagnostic spectrum of hepatic and pancreatic diseases in dogs.

  • Tc-99m HMPAO WBC scintigraphy is a highly sensitive and specific method for detection and localization of infection and abscess formation. Nevertheless, WBC accumulation in some neoplastic lesions has been reported. We experienced a case with unusual increased uptake of Tc-99m HMPAO WBC in chondrosarcoma. Although the exact cause ms unclear, the possible mechanism is discussed.

  • The perineum is comprised of diverse anatomic structures with mixed sympathetic and somatic innervation. The coccyx is innervated by the coccygeal nerves and branches of the fifth sacral root. Recently, ganglion impar block has been introduced as an alternative means of managing intractable pain of sympathetic origin, coccygodynia by trauma, tenesmus and perineal hyperhydrosis. We managed a 59-year-old female patient who had suffered from perineal pain by metastasis of cervical cancer. Approach to impar ganglion through the anococcygeal ligament was impossible because her coccyx was hyperflexed anteriorly by old fracture. But we could perform ganglion impar block successfully by approach through the separation of sacrum and coccyx.
