Introduction: The worldwide incidence of breast cancer has increased rapidly in recent years. The scenario of Eastern India is also showing the same trend. It is necessary to study the utility of HER-2/neu as a prognostic factor in breast cancer survival. However, there have not been detailed studies in this respect with the breast cancer patients of Eastern India. Thus this study was conducted. Materials and Methods: In this hospital-based study 86 breast cancer patients attending a breast clinic of a reputed institute of Eastern India and having invasive ductal carcinomas were observed for a period of 5 years after surgery. Associations between 5 years observed survival and status of ER, PR and HER-2/neu of the patients were critically evaluated. Results: There was statistically significant association between survival pattern for 5 years and the HER-2/neu status (p=0.00001). Better survival was observed for the patients with HER-2/neu negative tumors 67(100%) compared to HER-2/neu positive tumors 7(36.8%). Conclusions: There is strong interaction between survival and HER-2/neu expression of breast cancer patients. Thus the patients with HER-2/neu positive tumors need to be treated aggressively.

This study aimed at examining the effects of percutaneous electrical nerve stimulation(PENS) applied to different parts of the streptozotocin(STZ) induced diabetic rats on the change of glucose level and spinal neuron excitability. A total of twenty-eight SD rats, divided into four groups, were used as experiment animal. Experiment group I, the normal control group, was composed of normal rats without diabetes induction. Experiment group was composed II of the rats without any treatment after experimental diabetes induction. Experiment group III was composed of the rats with 2 Hz and $200\;{\mu}s$ of PENS to the acupuncture points related with diabetes for 20 minutes after diabetes induction. Experiment group IV was composed of the rats with 2 Hz and $200\;{\mu}s$ of PENS to the parts unrelated with diabetes for 20 minutes after diabetes induction. The results can be summarized as follow: As for glucose level, the group I showed no change within normal range, and the group III showed significant increase, compared with other groups (p<0.05). As for the change of H latency, M and H amplitude, the group III showed significant differences in decrease of latency and amplitude (p<0.05). As for Hmax/Mmax ratio, the normal and other groups showed no significant differences in decrease of amplitude. It can be concluded from the above results that PENS to the acupuncture points of the STZ-induced diabetic rats was effective for spinal neurone excitability, in particular, for those of the group with PENS to the acupuncture points. This study was conducted in the period of acute diabetes induction, and therefore, further study should be conducted in the period of chronic diabetes to research both acute and chronic diabetes.

Commercial bivalent killed Salmonella vaccine Salenvac-T has been used in several countries in order to prevent salmonellosis with Salmonella enterica serovars Enteritidis (SE) and Typhimurium (ST) in poultry. However, this vaccine has not been used in poultry farms in South Korea. In this study, we evaluated the efficacy of Salenvac-T vaccine to protect against the challenge of virulent SE and ST, and the effect of the vaccine on egg production and mortality in layer hens. The colonization of liver, spleen and cecum with challenged SE and ST was reduced in vaccinated chickens compared with that of unvaccinated control group. The twice vaccination with Salenvac-T induced elevated antibody responses against both SE and ST detected by enzyme-linked immunosorbent assay (ELISA). The higher average hen-day production was observed in the vaccinated layer hens than in the unvaccinated layer hens without significance. The average mortality was lower in the vaccinated layer hens during the experiment period. The antibody responses to both SE and ST were persistently detected in the vaccinated layers. In summary, vaccination with Salenvac-T reduces colonization of internal organs and induces good antibody responses, thereby results in higher performance and lower egg contamination with SE and ST in layer hens.

Recent advancements in basic research on the process of secondary neurulation and increased clinical experience with caudal spinal anomalies with associated abnormalities in the surrounding and distal structures shed light on further understanding of the pathoembryogenesis of the lesions and led to the new classification of these dysraphic entities. We summarized the changing concepts of lesions developed from the disordered secondary neurulation shown during the last decade. In addition, we suggested our new pathoembryogenetic explanations for a few entities based on the literature and the data from our previous animal research. Disordered secondary neurulation at each phase of development may cause corresponding lesions, such as failed junction with the primary neural tube (junctional neural tube defect and segmental spinal dysgenesis), dysgenesis or duplication of the caudal cell mass associated with disturbed activity of caudal mesenchymal tissue (caudal agenesis and caudal duplication syndrome), failed ingression of the primitive streak to the caudal cell mass (myelomeningocele), focal limited dorsal neuro-cutaneous nondisjunction (limited dorsal myeloschisis and congenital dermal sinus), neuro-mesenchymal adhesion (lumbosacral lipomatous malformation), and regression failure spectrum of the medullary cord (thickened filum and filar cyst, low-lying conus, retained medullary cord, terminal myelocele and terminal myelocystocele). It seems that almost every anomalous entity of the primary neural tube may occur in the area of secondary neurulation. Furthermore, the close association with the activity of caudal mesenchymal tissue in secondary neurulation involves a wider range of surrounding structures than in primary neurulation. Although the majority of the data are from animals, not from humans and many theories are still conjectural, these changing concepts of normal and disordered secondary neurulation will provoke further advancements in our management strategies as well as in the pathoembryogenetic understanding of anomalous lesions in this area.

Background: Intraoperative fluids are still poorly studied in veterinary medicine. In humans the dosage is associated with significant differences in postoperative outcomes. Objectives: The aim of this study is to verify the influence of three different fluid therapy rates in dogs undergoing video-assisted ovariohysterectomy. Methods: Twenty-four female dogs were distributed into three groups: G5, G10, and G20. Each group was given 5, 10, and 20 mL·kg^-1·h^-1 of Lactate Ringer, respectively. This study evaluated the following parameters: central venous pressure, arterial blood pressure, heart rate, respiratory rate, temperature, acid-base balance, and serum lactate levels. Additionally, this study evaluated the following urinary variables: urea, creatinine, protein to creatinine ratio, urine output, and urine specific gravity. The dogs were evaluated up to 26 h after the procedure. Results: All animals presented respiratory acidosis during the intraoperative period. The G5 group evidenced intraoperative oliguria (0.80 ± 0.38 mL·kg^-1·h^-1), differing from the G20 group (2.17 ± 0.52 mL·kg^-1·h^-1) (p = 0.001). Serum lactate was different between groups during extubation (p = 0.036), with higher values being recorded in the G5 group (2.19 ± 1.65 mmol/L). Animals from the G20 group presented more severe hypothermia at the end of the procedure (35.93 ± 0.61℃) (p = 0.032). Only the members of the G20 group presented mean potassium values below the reference for the species. Anion gap values were lower in the G20 group when compared to the G5 and G10 groups (p = 0.017). Conclusions: The use of lactated Ringer's solution at the rate of 10 mL·kg^-1·h^-1 seems to be beneficial in the elective laparoscopic procedures over the 5 or 20 mL·kg^-1·h^-1 rates of infusion.

본 연구는 생쥐 미성숙란올 초자화 동결-융해하였올 때, 체외/체내 배발달능을 검토하고자 실시하였다. 생쥐 미성숙란은 동해제인 EFS40(40% ethylene glycol, 18% ficoll, 0.5 M sucrose)으로 초자화동결되었으며, 융해 후 16 시간동안 체외성숙을 유도하여, 제 1 극체가 나타난 성숙된 난자를 1~2$\times$$10^{6}$$m\ell$ 농도의 정자로 체외수정시킨 다음, 난할율 ($\geq$ 2- 세포기)과 체외 / 체내 발달율을 조사하였다. 쥐 미성숙란을 초자화 동결 융해하였던 군 (63.1%)의 체외성숙율은 동해제 노출군 (67.5%)과 대조군(66.3%)에 유사하게 나타났으나, 초자화 동결군의 난할율과 배반포형성율 (64.9, 59.0%)은 동해제노출군 (83.7, 74.7%)과 대조군 (90.7, 83.7%) 에 비해 유의하게 감소하였다 (p＜0.05). 그러나, 초자화 동결 융해하였던 생쥐 미성숙란으로부터 얻어진 배반포기배를 가임신 생쥐에 이식하였을 때, 체내발달율인 전체착상율 (31.3%)과 착상된 배로부터 발달된 산자형성율 (66.7%)은 대조군의 결과 (40.8%, 58.1%)와 각각 비교하였을 때 유의차가 인정되지 않았다. 따라서, 생쥐 미성숙란을 초자화 동결-융해하였을 때, 체외발달율은 유의하게 감소하였지만 생성된 배반포기배로부터의 산자발달율은 대조군과 유사하게 나타나, EFS40을 이용한 초자화 동결 방법은 생쥐 미성숙란 동결에 유용하게 이용될 수 있다는 것을 알 수 있었다.

In order to ensure good animal health and performance, it is essential to produce forages with high feeding value and good hygienic quality. However, huge amounts of forages consumed by ruminants are contaminated with mold prior to harvest or during storage as hay, straw or silage. These mold can grow in forages only when nutrients are available, correct temperature exist, oxygen is present, and unbound water is available. Fungal 'species can be divided into two groups: field fungi and storage fungi. Field fungi invade the forages while the crop is still in the field, require high moisture conditions, and are such as species of Fusarium, Alternaria, Clodosporium, Diplodia, Gibberrella and Helminthosporium. Storage fungi invade forages during storage and need less moisture than field fungi. These such as species of Aspergillus and Penicillium usually do not occur any problem before harvest. Mold growth can spoil the nutritional aspects of the forages and also results in secondary metabolites that are highly toxic to animal, humans and plants. Moldy feeds are less palatable and may reduce dry matter intake. This, in turn, leads to a reduction of nutrition intake, reducing weight gains or milk production. Performance losses of 5 to 10 percent are typical with moldy feeds. Mycotoxins are toxic substances produced by fungi (molds) growing on crops in the field or storages. While greater than 400 mycotoxins have been chemically identified, the biological or veterinary medical impact of only several mycotoxins is known. Mycotoxins have attracted considerable attention as potential causes for poor performance and health disorders in domestic livestock. They can be carcinogenic, hepatotoxic, hematotoxic, immunosuppressive, estrogenic, or mutagenic. So, feeding moldy forages has adverse effects on animal health and milk consumers. Also, this author reported that rice straw hay was contaminated mycotoxigenic fungi such as Penicillium roqueforti and Fusarium culmorum in Korea. Therefore, it is an urgent need to develop an improved post harvest storage method to reduce nutrient loss and mycotoxin contamination of forages, which will have a positive impact on human health.
