  • A bitch was presented for investigation of the mass in left 5th mammary gland. The partial mastectomy was performed and submitted for the histopathological diagnosis. The mammary mass was firm and white colored. The cut surface was separated with several lobules and developed vessels. The central area of the mass formed the cavity filled with inflammatory exudates. The dominant component of the tumor was the bundles of spindle-shaped cells. Some tumor cells possessed atypical nuclei and were arranged in a solid nest. Cysts were microscopically composed of hemorrhage, necrosis, and exudates, partially surrounded by tumor cells and granulation tissues. Histopathologically, the mammary mass revealed spindle cell carcinoma. The bitch made a complete recovery following the mastectomy. This case was a rare mammary spindle cell carcinoma in a dog.

  • Flurbiprofen, one of potent nonsteroidal antiinflammatory drugs, has several systemic side effects due to dose dumping effect following oral administration of its conventional solid dosage forms. To reduce these side effects and to sustain therapeutic concentration of the drug, matrix tablets of flurbiprofen were prepared and evaluated for sustained release from the tablets. The matrix tablets of flurbiprofen were prepared with Eudragit, Pluronic, (anhydrous) lactose and colloidal silicon dioxide employing two different preparation methods, wet granulation and direct compression. The dissolution rates of the tablets were evaluated using KP 2 method. Formulation factors that affected dissolution rates of flurbiprofen were the type and content of Eudragit, the type and content of Pluronic, and the tablet preparation method. Several formulations of the matrix tablets showed dissolution patterns close to the simulated profile using pharmacokinetic parameters of flurbiprofen.

  • The most common cause of the decannulation difficulty is the trauma. This may be accidental, iatrogenic such as prolonged intubation, high tracheostomy, secondary infection, formation of granulation tissue, improper use of cannula and wide resection of anterior tracheal wall. Another common cause is psychologic dependency. Treatments may be categorized into dilatation with or without injection of steroid, dilatation and prolonged stent, luminal augmentation and resection of the stenosis with primary reanastomosis. Recently authors experienced a case of the decannulation difficulty in a 2 - year - old which was developed after tracheostomy for the removal of bronchial foreign body and was treated with a silicon T -tube stent with good result.

  • Tracheal stenosis is relatively common complication after tracheal intubation or tracheostomy for a long time. We experienced 10 cases of tracheal stenosis with various causes, prolonged intubation or tracheostomy caused the tracheal stenosis in seven, one after advanced cancer of the lung, one after inhalation burn, and the other was palliative management for tracheal stenosis by Gianturco type tracheal stent. We tried to correct this stenosis applying three tracheal stent and one Montgomery T-tube as a palliative approach, but failed in two, one restenosis due to regrowing of granulation tissue with scarring or another metastatic spread of cancer to systemic organs after 3 months of placing the stent. Tracheal circumferential resection and end to end anastomosis were done in seven, and obtained one postoperative complication as subglottic stenosis was followed by Montgomery T-tube and reoperation later. With the brief review of references, we report the cases.

  • A total of 499 stomachs consisted of 393 slaughter and 106 breeding pigs from industrial farm was examined for ulcerative lesions grossly and microscopically. The relationship between the ulcerative lesions and stomach contents was also examined. 1. The majority of stomachs has one or more lesions of ulcerative process, including parakeratosis(64.1%), erosions(10.2%), acute ulcers(2.8%), chronic ulcers(1.4%), and scars(0.8%). 2. The incidence and the degree of the esophagogastric lesions in the breeding pigs were similar to those of the slaughter pigs. But ulcerative lesions of the fundic lesions in the breeding pigs were found to be more remarkable than those of the slaughter pigs. 3. The stomach contents of the pigs having gastric ulcers were mostly fluid in nature, which were dry in the normal stomach. 4. Histologically, muscular hypertrophy, connective tissue hyperplasia and vascularity were shown in the ulcerative lesions of the esophagogastric portion. Thrombosis, necrosis and granulation tissue formation were found frequently.

  • Enhanced biological phosphorus removal (EBPR) behavior and microbial characteristics in the anaerobic-aerobic SBR (PAO SBR) and the anaerobic-anoxic SBR (DPAO SBR) were examined in this research. For 392 days of operation, both SBRs have exhibited a good EBPR (or denitrifying EBPR) performance. $P_{release}/P_{influent}$ ratio was highest in both reactors after the stabilization, while the efficiency of phosphorus removal was decreased since the sludge granulation has been visually observed within the reactor. The comparative analysis of Pyrosequencing-based microbial population between PAO and DPAO sludges showed indirectly that Dechloromonas spp. could utilize $O_2$ and $NO_3{^-}-N$ as an electron acceptor and Accumulibacter phosphatis use only $O_2$ in EBPR system. Also, we concluded that Thauera spp. as a denitrifier contribute significantly to the anoxic phosphorus removal in the DPAO system.

  • Cryptogenic organizing pneumonia (COP) is a type of idiopathic interstitial pneumonia with an acute or subacute clinical course. Bilateral lung consolidations located in the subpleural area and bronchovascular bundle are the most common findings on chest high-resolution computed tomography. The pathologic manifestations include granulation tissue in the alveoli, alveolar ducts, and bronchioles. COP responds fairly well to glucocorticoid monotherapy with rapid clinical improvement, but recurrence is common. However, treatment with combined immunosuppressant agents is not recommended, even if the COP patient does not respond to glucocorticoid monotherapy with expert opinion.

  • The purpose of this study is to investigate the effects of the low power Helium Neon-Infra Red(HeNe-IR) laser and the special electromagnetic therapeutic apparatus stimulation, which is usually designated as TDP by using the initial of Tending Diancibo Pu which is the Chinese inscribed with English, on wound healing in rat. The seventy-five Sprague-Dawley adult female and male rats were assigned to the experimental and control groups. Each rat was anesthetized with pentobarbital sodium, and three full-thickness incisions with 12mm length wert made on the back of the half cf the rats and three deep second degree burns were made on the back of the remainder of the rats. From 34 hours after being injured, the rats of the experimental laser group were irradiated with the 157mW electric power HeNe-IR laser for 2 minutes every day and the rats of the experimental TDP group were stimulated with TDP irradiation with the 4km spot distance for 20 minutes every day during the 17 days. The rats were sacrificed and the wound parts of its were incised on the first day, 4th day, 7th day, 10th day and 17th day respectively after the beginning of wound treatment with laser and TDP irradiation. The incised wound parts were processed appropriately for the light microscopic and electron microscopic examination. The length of incised wound was measured with microcaliper before the wound part was incised. There was a significant decrease in the length of the incised wound of the experimental laser and TDP group, compared with that of control group at 4th day, 7th day and 10th day(p<0.01) after surgery. Through the histological examination of the wound site, the more rapid epithelialization and collagen formation in experimental groups were showed, compared with control group. The histological results were analyzed and summarized as the follows; The epidermis begins to be regenerated and the granulation tissue begins to be changed to the mature pattern in the H-E stained incised skin of the laser and TDP treatment group on the 4th day. The epidermis shows the complete regeneration and the granulation tissue in the dermis in mostly to be matured in the laser and TDP treatment group on the 7th day, compared with control group. The chronic inflammatory cells are oberved and the necrosis of the collagen fibers are partially observed in control group on the 10th day. The dermis of the laser and TOP treatment group reveals relatively compactly arranged collgen bundles with the mature collagen fibers on the 10th day. The epidermis and dennis of the laser and TDP group are repaired normally and the hair follicles are well regenerated on the 17th day. The mild edema and the granulation tissue is observed in the dermis of the control groups and the delayed treatment process is observed on the 17th day. The Most of proliferated collagen fibrils are found to be compact and regular in electron micrograph of burn skin of the laser treatment group on the 10th day hut the interstitial eadema and some inflammatory cells are found in the control group. The above results suggest that through the visual and histological examination the epithelized epithelium and the proliferation of the collagen liters in the dermis occur very effectively with the low power laser treatment and the TDP treatment in the incised wound healing and the burn wound healing.
