Delayed arrival of blood samples from the field and a large number of samples delivered often causes delay in sample analysis leading to inaccurate measurements. Therefore, this study aimed to assess whether prolonged storage in refrigerator could influence the stability of cattle blood samples and to establish an optimal time limit for complete blood count (CBC) parameters and blood gas and electrolyte (BGE) parameters analyses. Samples collected from healthy cows were tested immediately for CBC and BGE using automated hematology, blood gas and electrolyte analyzers. Samples were kept in refrigerator at 4℃ and analyzed after 6 h, 12 h, 24 h, 48 h, 72 h, 120 h, and 192 h of storage. Mean differences between observations were assessed at 5% significance level using ANOVA and Duncan's multiple range test. Total CBC parameters and the platelet profile remained stable for 192 h, except for MCHC. Among leukocyte-related counts, NEU and EOS remained stable for 192 hours. WBC and LYM, and MONO values produced inconsistent measurements which recovered its initial measurement after 12 h and 24 h of storage, respectively, then remained stable until 120 h. Among the blood gas indices, PCO2, PO2, tCO2, and BE showed declining and significant changes over time, but pH, tHb, and SO2 remained stable for 192 h. Electrolyte status in the blood showed that ions are unstable and tend to change in as early as 6 h of storage. This study established that cattle blood specimens for CBC analysis can be stored for 120 h at 4℃, but specimens for BGE analyses must be tested within 6 to 24 h.

Background: Extracorporeal life support (ECLS) in patients with hematologic malignancies is considered to have a poor prognosis. However, to date, there is only one case series reported in the literature. In this study, we compared the in-hospital survival of ECLS in patients with and without hematologic malignancies. Methods: We reviewed a total of 66 patients who underwent ECLS for treatment of acute respiratory failure from January 2012 to December 2014. Of these patients, 22 (32%) were diagnosed with hematologic malignancies, and 13 (59%) underwent stem cell transplantation before ECLS. Results: The in-hospital survival rate of patients with hematologic malignancies was 5% (1/22), while that of patients without malignancies was 26% (12/46). The number of platelet transfusions was significantly higher in patients with hematologic malignancies ($9.69{\pm}7.55$ vs. $3.12{\pm}3.42units/day$). Multivariate analysis showed that the presence of hematologic malignancies was a significant negative predictor of survival to discharge (odds ratio, 0.07; 95% confidence interval, 0.01-0.79); p=0.031). Conclusion: ECLS in patients with hematologic malignancies had a lower in-hospital survival rate, compared to patients without hematologic malignancies.

The aim of this study was to estimate the shelf life of butter and cheese products, with shelf life being a guide used to determine the storage period of food before deterioration. Butter and cheese samples stored at $10^{\circ}C$ and $15^{\circ}C$ had a shelf life of 221 d, while those stored at $25^{\circ}C$ and $35^{\circ}C$ had a shelf life of 109 d. Quality changes, including total cell count, coliform counts, Listeria monocytogenes counts, acid value, moisture content, pH, acidity and overall sensory evaluation, were monitored. In order to pass the overall sensory evaluation, a quality score of 5 points on a 9-point scale was required. For other quality criteria, legal quality limits were established based on the "Process Criteria and Ingredient Standard of Livestock Products" by the Animal, Plant and Fisheries Quarantine and Inspection Agency (Republic of Korea). The nonlegal quality limit was estimated by regression analysis between non-quality criteria (y) and overall sensory evaluation (x). The shelf life was estimated based on the number of days that the product passed the quality limit of the quality criteria. The shelf life of samples stored at $10^{\circ}C$, $15^{\circ}C$, $25^{\circ}C$ and $35^{\circ}C$ was 21.94, 17.18, 6.10 and 0.58 mon, respectively, for butter and 10.81, 9.47, 4.64 and 0.20 mon, respectively, for cheese.

The papillary patterned lesion of thyroid may be challenging with many diagnostic pitfalls. Tumor stroma plays an important part in the determination of the tumor phenotype. CD34 is thought to be involved in the modulation of cell adhesion and signal transduction as CD34(+) fibrocytes are potent antigen-presenting cells. Smooth muscle actin (SMA) positivity could be diagnostic for fibroblast activation during tumorigenesis. We aimed to examine the expression of CD34 and alphaSMA in the stroma of papillary thyroid hyperplasia, papillary thyroid carcinoma and papillary tumors of uncertain malignant potential in order to elucidate their possible differential distribution and roles. A total number of 54 cases with papillary thyroid lesions were studied by routine H&E staining, CD34 and ASMA immunostaining. ASMA was not expressed in benign papillary hyperplastic lesions while it was expressed in papillary carcinoma, indicating that tumors have modulated stroma. Although the stroma was not well developed in papillary lesions with equivocal features of uncertain potentiality, CD34 was notable in such cases with higher incidence in malignant cases. So ASMA as well as CD34 could predict neoplastic behavior, pointing to the importance of the stromal role. Differences between groups suggest that the presence of CD34 + stromal cells is an early event in carcinogensis and is associated with neoplasia, however ASMA+ cells are more likely to be associated with malignant behavior and metastatic potential adding additional tools to the light microscopic picture helping in diagnosis of problematic cases with H&E.
Objective: To determine the diagnostic performance of hematuria as a screening test for urinary bladder infiltration in cervical cancer patients with a prospective study design. Materials and Methods: Newly diagnosed cervical cancer patients at Srinagarind hospital from 14 June 2011 to 30 April 2012 were enrolled in this study. We collected midstream urine samples for urinalysis from every patient before routine cystoscopic exam for clinical staging. The presence of 3 or more red blood cells (RBCs) per high power field was defined as positive for hematuria. A two-by-two table was used to determine the diagnostic performance of hematuria to detect urinary bladder mucosal infiltration using cystoscopy and biopsy as the gold standard. Result: A total of 130 were patients included, 54 of which (41.5%) had hematuria. Of these, four patients (3.08%) had pathological report from cystoscopic biopsy confirmed metastatic squamous cell carcinoma. The sensitivity, specificity, PPV, NPV, and accuracy of hematuria as a screening test to detect urinary bladder mucosal infiltration of cervical cancer were 100%, 60.3%, 7.4%, 100%, and 61.5%, respectively. There was no single case of urinary bladder mucosal infiltration in patients initially staged less than stage III. Conclusions: Hematuria can be used as a screening test to detect urinary bladder mucosal infiltration of cervical cancer. This can reduce the number of cervical cancer patients who really need to undergo cystoscopy as a staging procedure to less than half and to less than 20% if stage III or more were included without missing a single case of urinary bladder mucosal infiltration.

Since there is evidence that human papillomavirus (HPV) may play some role in oral carcinogenesis, we investigated the presence of HPV in a group of Pakistani subjects with normal oral cavity using real-time PCR analysis. Two-hundred patients attending the Dental Department, Sandaman Provincial Hospital, Balochistan, Pakistan, were recruited. After interview, oral epithelial cells were collected by scraping and subjected to DNA extraction. The HPV-positive DNA samples were further analyzed using primer sets specific for HPV-16 and -18. It was found that out of 200 DNA samples, 192 were PCR-positive for the ${\beta}$-globin gene and these were subsequently examined for the presence of HPV DNA. Among these, 47 (24.5%) were HPV-positive with the virus copy number ranged between 0.43-32 copies per 1 ${\mu}g$ of total DNA (9-99 copies per PCR reaction). There were 4 and 11 samples containing HPV-16 and -18, respectively. Additionally, one sample harbored both types of HPV. Among the investigated clinical parameters, smoking habit was associated with the presence of HPV (p = 0.001) while others indicated no significant association. The prevalence of HPV in normal oral cavity in our Pakistani subjects appears to be comparable to other studies. However, the association between the presence of HPV and smoking warrants further investigations whether both of these factors can cooperate in inducing oral cancer in this group of patients.
The study was conducted to correlate the periparturient immune status in terms of neutrophil functions and cytokine expression in peripheral blood mononuclear cell culture with impending postpartum reproductive disorders in buffaloes. Forty pregnant buffaloes were observed for occurrence of postpartum reproductive disorders (PRD), i.e., metritis, endometritis and delayed uterine involution etc., during one week prepartum to four weeks postpartum period. A representative number (n = 6) of buffaloes that did not develop any PRD were included in group I (healthy, control), while the animals which experienced PRD were assigned into group II (PRD, n = 8). The blood samples were collected at weekly interval from one week prepartum to four weeks postpartum period considering the day of calving as 'd 0'. Differential leucocytes counts, superoxide and hydrogen peroxide production activity in isolated neutrophils and the mRNA expression profile of cytokines i.e., IL-2, IL-4 and IFN-${\gamma}$ in PBMC culture were studied in all the samples. A higher total leucocytes, neutrophil and band cells count along with impaired neutrophil functions i.e., lowered level of production of superoxide and hydrogen peroxide before parturition and during early postpartum period were observed in buffaloes developing PRD. Further, a lower expression of IL-2, IFN-${\gamma}$ and IL-4 mRNA in PBMC culture was observed at calving in buffaloes that subsequently developed PRD at later postpartum. Thus, suppression in neutrophil function and cytokine expression at prepartum to early postpartum period predisposes the buffaloes to develop postpartum reproductive disorders. Hence, monitoring of neutrophils function and cytokine expression profile would be effective to predict certain reproductive disorders at late pregnancy or immediately after parturition in buffaloes. In future, this may be a novel approach for determining suitable management and therapeutic decisions for prevention of commonly occurring reproductive disorders in farm animals.
Objectives This study was to investigate the effects of Yuhyangjeongtong-san on the carrageenin-induced acute inflammation and adjuvant-induced arthritis in rats. Methods Acute inflammation was induced by injection of 2% carrageenin 0.15 ml into right hind foot of rats. Control group was carrageenin injected and taken distilled water, treated group was carrageenin injected and taken Yuhyangjeongtong-san by orally once. 2 hours after injection, plantar temperature and paw volume were measured. 3 hours after, counts of white blood cell (WBC) were performed. Arthritis was induced by injection of complete freund's adjuvant (CFA) into base of tail. Control group was CFA injected and taken distilled water, treated group was CFA injected and taken Yuhyangjeongtong-san by orally for 10 days. 0,5,10 day, body weight, thickness of ankle joint and paw edema were measured. 10 day, counts of WBC, $interleukin-1{\beta}$ ($IL-1{\beta}$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level were analysed. Histochemical study of NADPH-d and immunohistochemical study of c-fos were performed. Results In the carrageenin-induced acute inflammation, neutrophils of treated group were significantly decreased compared with control group. In the adjuvant-induced arthritis, paw edema, total counts of WBC and TNF-${\alpha}$ level in paw exudates were significantly decreased compared with control group, and the number of c-fos positive neurons of treated group was significantly decreased compared with control group. Conclusions On the basis of these results, we concluded that Yuhyangjeongtong-san have anti-arthritic and anti-inflammatory effects.

The aim of the study was to investigate the inhibitory effects of calcium against intestinal cancer in vitro and in vivo. We first investigated the effects of calcium treatment in HCT116 and HT29 human colon cancer cells. At the concentration range of 0.8-2.4 mM, calcium significantly inhibited cell growth (by 9-29%), attachment (by 12-26%), invasion (by 15-31%), and migration (by 19-61%). An immunofluorescence microscope analysis showed that the treatment with calcium (1.6 mM) for 24 h increased plasma membrane ${\beta}$-catenin but decreased nuclear ${\beta}$-catenin levels in HT29 cells. We then investigated the effect of dietary calcium on intestinal tumorigenesis in $Apc^{Min/+}$ mice. Mice received dietary treatment starting at 6 weeks of age for the consecutive 8 weeks. The basal control diet contained high-fat (20% mixed lipids by weight) and low-calcium (1.4 mg/g diet) to mimic the average Western diet, while the treatment diet contained an enriched level of calcium (5.2 mg calcium/g diet). The dietary calcium treatment decreased the total number of small intestinal tumors (by 31.4%; P < 0.05). The largest decrease was in tumors which were ${\geq}$ 2 mm in diameter, showing a 75.6% inhibition in the small intestinal tumor multiplicity (P < 0.001). Immunohistochemical analysis showed significantly reduced nuclear staining of ${\beta}$-catenin (expressed as nuclear positivity), but increased plasma membrane staining of ${\beta}$-catenin, in the adenomas from the calcium-treated groups in comparison to those from the control group (P < 0.001). These results demonstrate intestinal cancer inhibitory effects of calcium both in human colon cancer cells and $Apc^{Min/+}$ mice. The decreased ${\beta}$-catenin nuclear localization caused by the calcium treatment may contribute to the inhibitory action.
This research was undertaken to determine the effects of the anticancer and immunosuppressive drug cyclophosphamide (CP) on the epididymis of the male rat in terms of ultrastructural alteration and protein analysis by SDS-PAGE at different groups; control group, 1 week group, 3 weeks group, 5 weeks group were treated with saline (control group) or CP at doses of 20mg/Kg/week, 1 time a week, respectively. In the cytoplasm of the principal cells on the epididymis, the mitochondrial outer and inner membranes were significantly swollen or disrupted. The cisterns of rough endoplasmic reticulum (rER) were also swollen, and a number of Golgi vesicles were increased, respectively. It is suggested that treatment with CP alters the specific cell organelles in all segments of the epididymis. CP caused changes in protein concentrations in cauda of epididymis after CP treatment. Total proteins of 30 to 39 species such as lactate dehydrogenase, carnitine acetyltransferase and acid phosphatase were expressed in the cauda fluid. Then the more CP was increased, the more concentration of proteins caused to decrease, synthesize or increase in epididymal cauda. In contrast to the control group, in particular 29KD and the other 10 proteins in the cauda fluid were decreased or disappeared, respectively, whereas 89KD and the other 6 proteins in the cauda, were increased or synthesized, respectively. The other proteins are not showed distinctive difference. Therefore, it is possible that CP at a high dose accumulation alters epididymal function with dose-related increase or decrease in specific activity of marked proteins for all regions of the epididymis (particularly, specific segment of cauda). These alterations could be mediated by direct, toxic effects of the drug on the epithelium or be secondary to changes in the spermatozoa as a result of the CP treatment.
