Inflammatory pseudotumor (IPT) is a term defining a mass characterized microscopically by a proliferation of bland mesenchymal spindle cells infiltrated by diffuse mixed inflammatory cells with a predominance of plasma cells and lymphocytes. Here, we show the primo vessel-like structure of the primo-vascular system (PVS) in a dog with IPT. A 6-years old male Mongrel dog was diagnosed with an abnormal mass (diameter 5.5 cm, weight 22 g) near left preputial area. The dog was submitted to the surgical detectomy of the mass. During the surgical operation, we observed primo vessel-like material. After fixations, the masses appeared macroscopically as lipoid-like, firm, white to grey masses, measuring $5{\times}8cm$. Histologically, cellular infiltration into the muscular layers was frequently seen. The mesenchymal proliferation remained the main component of the mass and was composed of myofibroblastic-like spindle cells characterized by globular, irregular nuclei containing open chromatin and a prominent nucleolus. On the basis of the histopathologic lesions, the subcutaneous mass was diagnosed as IPT. Also, we detected a primo vessel-like structures in some areas of the IPT tissues. These were observed as novel thread-like structures and bundle of tubular structures. To our knowledge, this report is the first case of primo vessel-like structure in a dog with IPT.

Thromboelastography (TEG) analysis consists of ${\alpha}$, G, K, MA, and R types of values and tests the effectiveness of blood clotting, which can be assessed for platelet function, clotting strength, and fibrinolysis. Canine heartworm diseases caused by Dirofilaria immitis, a vascular nematode, can lead to hyperfibrinolysis and hypercoagulation. In this study, G and MA values showed a statistically significant decrease over time after treatment of heartworm disease. Additionally, the ${\alpha}-value$ showed a high correlation with G, K, MA, and R values. The G value showed a high correlation with K and MA values, while The K value showed a high correlation with MA and R values. This study clearly found a gradual decrease in G and MA values in dogs with heartworm disease over time, both before and after treatment. This suggests that the clot formation time is longer and that the intensity of clot formation is lowered and may improve the risk of thromboembolism in dogs with heartworm disease.

The objective of this study was to evaluate the effect of electric fan installation for milk production improvement of dairy cattle in Thailand. The study was conducted using 2 small-holder dairy farms in Chiang Mai province, during April to August 2004. Electric fans were installed in front of each row of cows. Each of the two rows of cows in the barn was defined as an experimental unit, thus each farm had two experimental units. The fans were operated alternately in 7-day intervals between rows of cows within each farm during the day or between 8.00 am to 8.00 pm. Non-operation periods were used as control. Milk yields were recorded. Data on environmental temperature and humidity were obtained from Chiang Mai Meteorological Center. Result from statistically analysis of milk record suggested an interaction between lactation period and fan installation. Therefore, this interaction term of lactation period and fan installation (PERIOD_FAN) was added as a variable to the regression model. Due to the repeated data collection of milk yield from the same cow (alternate week), milk yield was analyzed by repeated measure analysis (Mixed model). Least square means were calculated for all levels and used to compare between each pair-wise values. The final data were collected from the total of 18 cows with 2,072 data. Overall means and SEM of milk yields and days in milk separated into farm were $14.7{\pm}0.06kg/day$ and $176.3{\pm}2.2days$, and $15.2{\pm}0.22kg/day$ and $202.5{\pm}3.7$ days for farm A and farm B, respectively. For multivariable analysis, only PERIOD_FAN and humidity were significantly associated with milk yield. Only the first period of lactation showed that the amount of milk yields during fan installation was higher than that of non-fan installation (p<0.05). Cows with fan installation produced approximately 1.2 kg/cow more milk than cows without fan installation during this period. In conclusion, the use of electric fan operated during the day time increased milk production of cows during the first period of lactation.

아일랜드 갈웨이주 고르트 근교에서 사육중인 11세, 쇼트혼 종 소가 분만에 도움을 필요로 하였다. 환축은 분만 당일에 기립불능으로 되었다. Lumbo-sacral space, GB3O, GB31, ST40 및 ST41에 덱사메타손 수침을 실시하였다. 또한 간이 뜸처치를 1차 치료 시 실시하였다. 2차 치료 시 환축은 기립이 불가능하였다. 3차 치료 시에는 환축은 자력으로 기립을 시도하였으나 매번 쓰러졌다. 그러나 환축은 분만 후 10일에 약간의 조력으로 기립이 가능하였다. 따라서 본 환축은 덱사메타손 수침 및 간이 뜸 처치의 병용으로 증상이 호전된 기립 불능 우 증례이었다.

Dogs exhibit patterns of health issues that vary by life stage. An understanding of disease incidence with respect to breed and age/life stage could be an important component of canine health management and welfare. This study aimed to describe the age-specific disease incidence of 3 small dog breeds that attended veterinary clinics in the Republic of Korea, based on data from electronic veterinary medical records (EVMRs). A total of 40,785 EVMRs from Maltese (n = 21,355), Miniature Poodle (n = 11,658) and Shih Tzu dogs (n = 7,772) were analyzed. Common health problems in 3 small dog breeds were 'diseases of the skin' and 'diseases of the ear,' respectively. Among dogs aged ≤ 3 years, 'preventive medicine' was the most common cause cited for veterinary clinic visits. Among dogs aged 4 to 8 years, the most frequent health problems were 'diseases of the skin.' Among dogs aged 9 to 13 years, 'heart diseases,' 'kidney diseases,' 'mammary gland tumor,' and 'neoplasia (unspecified)' were considerably more frequent, compared to the rates in dogs ≤3 years. Among dogs aged ≥ 14 years, 'heart diseases' and 'sneezing/cough' were the main health problems. In all breeds, the frequencies of 'diseases of circulatory system,' 'diseases of respiratory system,' 'diseases of the nervous system,' 'endocrine' and 'neoplasia' increased rapidly with aging. This surveillance could inform strategies for disease screening tests and management based on life stage in these dog breeds and enable more effective health management.

Two field studies were conducted to determine the efficacy of difructose anhydride III (DFA III) as a supplement in colostrum replacer (CR) for improving the general health status (judged on the basis of incidence of enteritis, bronchitis, and pneumonia) of group-housed suckling Japanese Black calves. In a preliminary study, CR supplemented with DFA III (6 g) was orally administered within 24 h of calving to eight individually reared calves fed colostrum (DFA III group) (Exp. 1). Subsequently, CR supplemented with DFA III (6 g) was orally administered twice within 2 and 12 h of calving to four calves (DFA III group) that were not fed colostrum (Exp. 2). In both experiments, the health status of the calves was assessed during the preweaning period. In Exp. 2, hematological and blood-chemistry parameters were analyzed 24 h after the second administration of CR and at 1 wk and 1 month after calving. The results were compared between the DFA III and control groups (without DFA III supplementation; Exp. 1: n = 10, Exp. 2: n = 4). In Exp. 1, the number of calves requiring medications for the treatment of enteritis, bronchitis, and pneumonia during the preweaning period was significantly (p<0.05) lower in the DFA III group than in the control group. In Exp. 2, supplementation of DFA III did not influence the gain in body weight of calves during the pre-weaning period. Calves in the DFA III group tended to require medications for a shorter duration than those in the control group (DFA III: 10.3 d/calf, control: 21.3 d/calf; p = 0.07). Significant differences (p<0.05) in the level of mean corpuscular hemoglobin, total protein, total cholesterol, and immunoglobulin (Ig)G were observed between the DFA III and control groups. These differences probably reflect the health and nutritional status of the calves. Additionally, the serum iron and lactoferrin concentrations at 24 h and 1 wk after calving, respectively, differed significantly between the 2 groups. These concentrations might reflect the incidence of infections after calving. The present study revealed that the administration of DFA III as a CR supplement may prevent diseases in group-housed calves during the pre-weaning period.

The in-vitro fertilization in human clinic and animal reproduction is a very important technique but the rate of success is still low. When the in-vitro fertilization and culture of gametes or embryos were done under the condition which Hema hydrogel chamber were implanted into the peritoneal cavity of mouse, the in-vitro fertilization and development of embryos could be significantly improved and the cell-block under in-vitro culture could be overcome. Also, the Rema hydrogel chamber was very useful for the protection of isolated blastomeres. It is concluded that the polymerized Hema (pHema) hydrogel chamber may be effectively used in the fields of embryo transfer and in vitro fertilization.
