Objective: Pegfilgrastim is recently introduced that is long acting G-CSF for prophylaxis of febrile neutropenia. Treatment of non-Hodgikin's lymphoma (NHL) with R-CHOP is classified with relative high risk of febrile neutropenia. The study evaluated the prophylactic effect of pegfilgrastim to reduce the incidence of febrile neutropenia associated with R-CHOP of patient in NHL. And the risk factors associated with the incidence of FN and related events were evaluated. Methods: This retrospective study reviews the Electronic Medical Record of 68 NHL patients who received R-CHOP chemotherapy in single center between September 2013 and August 2014. These patients were classified who receive prophylaxis pegfilgrastim or no prophylaxis. Results: Sixty eight patients received R-CHOP with NHL. In 144 cycles of patients receiving pegfilgrastim, compared with no prophylaxis 178 cycles, had a lower incidence of febrile neutropenia (5.5% vs. 23.6%, p = 0.001), grade 3 or grade 4 neutropenia (14.4% vs. 89.8%, p < 0.001) and neutropenia related events (p < 0.05). The risk of febrile neutropenia after prophylaxis was significantly associated with age ${\geq}65$ (OR: 5.87, 95% CI 1.07-32.27, p = 0.042), $IPI{\geq}3$ (OR: 7.2, 95% CI 1.31-39.6, p = 0.023), S.alb < 3.5 g/dL (OR: 31.01, 95% CI 6.32-152.17, p < 0.0001). In multiple logistic regression analysis, lower baseline serum albumin (OR: 21.1, 95% CI 3.8-116.98, p = 0.001) was significantly associated with occurrence of febrile neutropenia. Conclusion: The study recommends prophylactic pegfilgrastim through risk assessment of febrile neutropenia in patients with non-Hodgikin's lymphoma receiving R-CHOP.

Aspirin is widely used for treatment or prophylaxis of many diseases. Although aspirin is used chronically for preventing cardiovascular diseases especially, liver function is rarely monitored because of unpredictable and uncommon hepatotoxicity induced by aspirin. We evaluated changes in liver function indicators and compared to acetaminophen and NSAIDs. We retrospectively analyzed EMR data (n=28788) of patients who took study drugs and had liver function tests (LFT) during study period from 2009.7.1 to 2010.6.30 at a tertiary hospital and evaluated the above information. Patients not having LFT results at these three standard points of time (baseline, during medication, and after finishing medication) were excluded. During medication, mean changes of Alanine transaminase (ALT), Aspartate transaminase (AST), Total Bilirubin (TB) were increased and that of serum albumin (Alb) was decreased, with the largest effect from aspirin (n=461; 16.8, 14.9, 0.28, -0.24) and the smallest from celecoxib (n=127; 3.4, 5.2, 0.11, -0.16). In addition, aspirin caused more changes of blood liver function indicators in patient group with liver disease (n=128, 27.4, 26.9, 0.53, -0.3) than those in patient group without liver disease (n=357, 12.5, 13.1, 0.23, -0.24). Taking low dose aspirin for prophylaxis purpose with long-term medication may be associated with liver injury. Our study is just a signal regarding the possibility of hepatotoxicity among patients taking low dose aspirin in a hospital setting, and thus it needs to be further investigated.

This experiment was conducted to investigate the effect of fermented spent mushroom substrate (FSMS) on growth performance, blood profile, intestinal microflora and ammonia gas production of feces in broiler chickens. A total of three hundred sixty, 1-day-old male broiler chicks (Ross) were randomly divided into 3 groups with 6 replicates of 20 birds each. The treatments were control (free FSMS), 15% FSMS (basal diet with 15% FSMS) and 30% FSMS (basal diet with 30% FSMS). The final body weight and body weight gains were slightly improved in 30% FSMS than control (P<0.05). Feed intake and feed conversion were significantly improved as compared to those of the control groups. The Leukocytes of blood serum in FSMS groups were significantly decreased as compared to those of control groups. There are no significant differences among the groups in the contents of albumin (ALB), total cholesterol (TCHO), glucose (GLU), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in blood serum. The content of total glucose (TG) in 30% FSMS containing dietary groups was significantly decreased as compared to that of the control groups. The content of HDLC in 30% FSMS containing dietary groups was significantly increased as compared to that of the control group. The number of lactobacillus in the intestinal microflora were significantly increased in chicks fed FSMS groups. The ammonia gas production in FSMS groups was siginificantly decreased as compard to that the control groups. These results indicated that dietary FSMS exerted growth performance for feeding broiler.

This study was carried out to evaluate the effects of Dochetang for the treatment of chronic diarrhea in a 4 months-old-female Korean native calf. The calf was presented to the Wow Animal Clinic, Iksan with the history of chronic diarrhea for several weeks. The feces test did not reveal the presence of the parasites or microbes causing diarrhea in calf. The blood test was also negative to the virus that causes of diarrhea in calf. Adminstration of parenteral antibiotics resulted in improvement of the condition temporarily but diarrhea was recurred again after 2-3 weeks. Then the calf was treated with Dochetang administered orally once a day in an empty stomach for 15 days. Feces was significantly reduced in moisture on 7 days after initial treatment. On 9 days after initial treatment, the calf had normal appetite and defecation in physiological conditions. Blood samples were collected before administration and on 1, 2 and 3 weeks after initial administration of Dochetang for hematology and biochemistry. A significantly differences were observed in the white blood cell (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), albumin (ALB), glutamic pyrubic transaminase (GPT), inorganic phosphorus (IP) and magnesium (Mg), while no significant differences were seen in the red blood cell (RBC), hemoglobin (Hb), hematocrit (HCT), platelet (PLT), glucose (Glu), total protein (T-pro), glutamic oxaloacetic transaminase (GOT), blood urea nitrogen (BUN) and creatine (CRE). This study suggests that Dochetang administration can be a successful alternative therapeutic agent in instead of antibiotics for the treatment of chronic diarrhea in calves.

This study was conducted to investigate the effects of different water temperatures (8, 11, 14 and 17℃) on growth, survival and hematological parameters of juvenile chum salmon(Oncorhynchus keta) for eight weeks. At the end of the experiment, at 14℃, the final body weights of the O. keta group were the highest compared to the other groups. Also, the O. keta showed a higher tendency in the 14℃ group than the 8, 11, and 17℃ groups in terms of growth performances, including specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency (FE), weight gain (WG), and condition factor (CF). The survival rate (SR) was 100% at 8 and 11℃ groups, 96% at 14℃ group and 98% at 17℃ group. In the plasma components, the alanine aminotransferase (ALT) was significantly decreased at 17℃ group, whereas there was no significant change in the albumin (ALB), total protein (TP), sodium (Na⁺), potassium (K⁺) and chloride (Cl^-) levels. Among the whole-body composition of salmon, moisture, crude protein, and ash were not significantly affected by water temperature. However, crude lipid in the 8℃ group was significantly higher than in other water temperature groups. The results of this study demonstrated that the optimal temperature to stable growth performance for juvenile O. keta was 14℃.

Here, we investigated the effects of different nutrient requirements (NR) on blood metabolites, transferable embryo number after multiple superovulations with artificial insemination (AI), body condition score (BCS), and estrus cycle in Hanwoo cow. Nineteen Hanwoo cows were randomly divided into three groups (80%, 100%, and 120% NR, containing 6, 8, and 5 individuals, respectively) and fed based on the NR. In experiment 1, glucose, total cholesterol, triglyceride, blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase (ALT), non-esterified fatty acids (NEFA), albumin (ALB), and total protein (TP) were analyzed. In experiment 2, total number of recovered embryos and transferable embryos was examined after embryo recovery and multiple superovulations with AI. In experiment 3, body weight, BCS, and estrus cycle were examined. In experiment 1, total cholesterol was significantly different among the 80%, 100%, and 120% NR groups (126.5 ± 3.3, 152.6 ± 2.4, and 177.4 ± 1.8 mg/dL, respectively, p < 0.05). The triglyceride and BUN levels in the 120% NR group were significantly higher than those in the 80% and 100% groups (p < 0.05). The NEFA levels were significantly different among the 80%, 100%, and 120% NR groups (440.5 ± 18.2, 318.5 ± 23.1, and 195.1 ± 8.5 ЧEq/L, respectively, p < 0.05). The AST and TP levels in the 80% NR group were significantly lower than those in the 100% and 120% NR groups (p < 0.05). In experiment 2, the 120% NR group showed a higher percentage of transferable embryos than the 80% and 100% groups (p < 0.01). The mean body weight and BCS among the 80%, 100%, and 120% NR groups were significantly different (p < 0.05). The estrus cycle in the 80% NR group was delayed compared with the 100% and 120% NR groups (20.8 ± 0.2 and 21.2 ± 0.5 days, respectively). In conclusion, the blood metabolic tests proved that Hanwoo cows with 120% NR can produce a large number of transferable embryos. Thus, 120% NR is the appropriate feeding level for this type of cows as it results in the production of a large number of transferable embryos by multiple superovulations with AI.

The present study was carried out to investigate the potential adverse effects of 1,3-dichloro-2-propanol on pregnant dams after maternal exposure during the gestational days (GD) 6 through 19 in Sprague-Dawley rats. The tested chemical was administered orally to pregnant rats at dose levels of 0, 10, 30, or 90 mg/kg/day. During the test period, clinical signs, mortality, body weights, food consumption, serum biochemistry, gross findings, organ weights, and Caesarean section findings were examined. In the 90 mg/kg group, decreases in the body weight gain and food consumption, and increases in the weights of liver and adrenal glands were observed. Serum biochemical investigations revealed increases in aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholesterol (CHO), triglyceride (TG), alkaline phosphatase (ALP), and bilirubin (BIL) and decreases in glucose (GLU), albumin (ALB) and total protein (TP). In the 30 mg/kg group, a decrease in the food consumption and an increase in the liver weight were observed. Serum biochemical investigation also showed increases in CHO and TG and a decrease in glucose. Since there were no signs of maternal toxicity in the 10 mg/kg group, it is considered to be the no-observed-adverse-effect level (NOAEL) of 1,3-dichloro-2-propanol. It is concluded that successive oral administration of 1,3-dichloro- 2-propanol to pregnant rats for 14 days may cause significant toxicities in body weight and liver at a dose rate ${\geq}$ 30 mg/kg/day.

This experiment was carried out in order to elucidate the effect of NaCl(0.85%) acclimation on congestion symptoms in central venous sinuses(CVS) of gill filaments and on the alteration of blood constituents in cultured eels for 1, 2, 3, 4, 5, 6 and 7days after handling stress. After giving a handling stress on eels, the frequency of gill congestion was about 90%. It gradually decreased to 40% on the 3rd day, then increased to 60% on the 7th day in NaCl(0.85%) acclimation. The values of haematocrit(Ht), methemoglobin(Met-Hb), glucose (GLU), calcium($Ca^{++}$), lactic dehydrogenase(LDH), glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase(GOT) were lower than those of the control, whereas magnesium($Mg^{++}$) and haemoglobin(Hb) were higher than the control. However total protein(Tp) and albumin (ALB) levels similar to the control. When the fish after giving a handling stress were cultured in NaCl-free water as a control, the frequency of gill congestion and the value of blood components showed a similar pattern to that obtained from the NaCl acclimated experiments. However, in the early period(1-3day) after handling stress, NaCl acclimating slightly helped the natural tendancy of recovery. These results suggest that the frequency of gill congestion is not always reduced over the whole period of NaCl acclimation. However, the acclimation to NaCl solution may be a somewhat useful therapy for the gill congestion in stressed eels.

Endothelial cells are a vital constituent of most mammalian organs and are required to maintain the integrity of these tissues. These cells also play a major role in angiogenesis, inflammatory reactions, and in the regulation of thrombosis. Angiogenesis facilitates pulp formation and produces the vessels which are essential for the maintenance of tooth homeostasis. These vessels can also be used in bone and tissue regeneration, and in surgical procedures to place implants or to remove cancerous tissue. Furthermore, endothelial cell regeneration is the most critical component of the tooth generation process. The aim of the present study was to stimulate endothelial regeneration at a site of acute cyclophosphamide (CP)-induced endothelial injury by treatment with human umbilical cord-derived endothelial/mesenchymal stem cells (hEPCs). We randomly assigned 16 to 20-week-old female NOD/SCID mice into three separate groups, a hEPC ($1{\times}10^5$ cells) transplanted, 300mg/kg CP treated and saline (control) group. The mice were sacrificed on days 5 and 10 and blood was collected via the abdominal aorta for analysis. The alanine transaminase (ALT), aspartate aminotransferase (AST), serum alkaline phosphatase (s-ALP), and albumin (ALB) levels were then evaluated. Tissue sections from the livers and kidneys were stained with hematoxylin and eosin (HE) for microscopic analysis and were subjected to immunohistochemistry to evaluate any changes in the endothelial layer. CP treatment caused a weight reduction after one day. The kidney/body weight ratio increased in the hEPC treated animals compared with the CP only group at 10 days. Moreover, hEPC treatment resulted in reduced s-ALP, AST, ALT levels compared with the CP only group at 10 days. The CP only animals further showed endothelial injuries at five days which were recovered by hEPC treatment at 10 days. The number of CD31-positive cells was increased by hEPC treatment at both 5 and 10 days. In conclusion, the CP-induced disruption of endothelial cells is recovered by hEPC treatment, indicating that hEPC transplantation has potential benefits in the treatment of endothelial damage.

Metabolic profile test is used to evaluate nutritional imbalance and metabolic disease in dairy cows. The reference intervals of metabolic parameters may change according to nation, region, decades, and maintenance system. Despite the need to be periodically updated for the reference intervals of metabolic parameters, it has rarely been investigated in Korea. Therefore, this aim of study was to provide the reference intervals of metabolic parameters using dairy cows surveyed in Korea during recent years. A metabolic profile test was conducted for 2,976 clinically healthy dairy cows in Korea. Blood samples were collected for the analysis of serum metabolites. This study provided reference intervals of thirteen metabolic parameters (${\beta}$-hydroxybutyrate [${\beta}-HB$], non-esterified fatty acids [NEFA], glucose, total cholesterol [T-COL], total protein, albumin, globulin, blood urea nitrogen [BUN], aspartate aminotransferase [AST], gamma-glutamyl transferase [GGT], calcium, phosphorus, and magnesium). BUN and AST values of the current study were higher than those of previous studies. In the present study, the other metabolic parameters showed low or similar value compared to previous results. Moreover, ${\beta}-HB$, NEFA, T-COL, ALB, BUN, AST, and GGT values were affected by lactation period. This study provided information on the reference intervals of metabolites in healthy dairy cows in Korea. The reference intervals from the present study would be useful in managing and diagnosing disease of dairy cows. However, careful attention should be given in interpreting disease condition for metabolites affected by lactation.
