  • This study hypothesized that dietary feed additive containing probiotics alter either immune-related serum substances or serum metabolites in Hanwoo heifers. A probiotic treatment was given at 0.5% top-dressing of concentrate diet for 6 months. The change of immunological indicators in the blood was analyzed under LPS (Lipopolysaccharide) challenge. One day before administration of LPS, all heifers were fitted with an indwelling jugular vein catheter for serial blood collections. Both a serum tube and an EDTA-coated tube were collected at 30-min intervals from - 2 to 8 hours relative to the LPS challenge at time 0 ($1{\mu}g/kg$ of BW). Serum was used for analyzing albumin (ALB), glucose (GLU), total protein (TP), triglycerides (TG), phosphorus (IP), and non-esterified fatty acids (NEFA). Plasma was used for analyzing white blood cell (WBC), red blood cell (RBC), platelet (PLT) and inflammation-related factors (NE, LY, MO, EO, BA, Hb, HCT, MCV, MCH, MCHC, RDW, MPV). There were significant differences in ALB, GLU, TG, IP, and NEFA concentration with the passage of hours post challenge (p < 0.05). The level of ALB, GLU, TG, and IP showed significant difference (p < 0.05) between treatments. However, none of the data showed interaction between time and treatments (p > 0.05). The level of WBC, EO, LY, and MO were reduced after LPS challenge (p > 0.05). In conclusion, LPS challenge after dietary supplementation of probiotics changed the levels of both serum metabolites and inflammation-related factors. The increase of GLU and TG indicated a probiotics-positive response under LPS challenge (p < 0.05).

  • The liver is one of the most common sites of cancer in the world, hepatocellular carcinoma (HCC) predominating. HCC is the sixth most common cancer and the third leading cause of cancer related death overall. Hepatitis C is a major risk factor and HCV is a rapid spreading virus which has become a problem globally, including in Pakistan. Interferon alpha therapy is used against HCV disease to regulate cell reproduction and to boost the immune system. In minute amounts interferon alpha is produced naturally by the immune system in HCV patients in response to hepatitis C virus and binds to receptors in the target cells and starts transcription of 20-30 genes due to which it develops an antiviral influence. Interferon is also administered artificially to overcome HCV disease and remove the biological effect of the virus from the infected site. The use of interferon or Peg-IFN plus Ribavirin treatment is also associated with adverse effects on body. For the current study, a convenient sample of 156 HCV positive patients of both males and females were taken. To collect blood CP and ALT, a reduction of level data and other important information were collected from the patients at regular intervals. Findings were 11.4 % in the red blood cells (RBC), 9.64 % in the total leukocyte count (WBC), 8.4 % in the hemoglobin levels (HB), 30.3 % in the platelet (Plt) count in both sexes. There was significant reduction in ALT levels due to Pegylated interferon plus ribavirin therapy. Hence strict haemotological monitoring of blood CP and ALT levels is necessary at regular intervals to reduce severe side effects which may lead to morbidity and mortality.

  • Blood tests have been used to develop treatment plans, such as disease diagnosis, treatment effect, and prognosis determination in livestock. The present study examined changes in the blood count, including RBCs, WBCs, and platelets, before and after grazing among the Korean native cattle grazing from spring to autumn. The study compared the blood count of livestock group (A, n=34) that returned from the rangeland to cowshed every evening and livestock group (B, n=21) that were not returned from the rangeland to cowshed every evening during the grazing period. Hematological parameters such as RBC, hemoglobin, hematocrit, MCV, and WBC, neutrophil, eosinophil, monocyte, and lymphocyte were determined using a blood cell analyzer. Livestock group (A) showed significant differences in the values of RBC, MCV, MCHC, WBC, EOS, and LYM. Livestock group (B) showed significant differences in the values of RBC, Hb, HCT, MCV, MCH, PLT, NEU, and BAS. In particular, the RBC count decreased after grazing when compared with that before grazing. Compared with that before grazing, low RBC count was maintained from the first to fifth month of grazing. The WBC count increased from the fourth month of grazing, whereas the EOS count increased from the second month of grazing. These results suggest that the values of RBC and WBC vary before and after grazing, and also with the grazing period. Furthermore, it is necessary to develop a detailed feeding management based on these values of blood analysis for livestock that are raised continuously in the rangeland.

  • Objectives: The purpose of this study was to examine the effects of Ohmae-hwan (OMH) and Mume Fructus (MF) on inflammatory bowel disease (IBD). Methods: Mice were divided into 4 groups: a normal group, control group, MF group, and OMH group. Three groups, excluding the normal group, were fed a 5% solution of dextran sulfate sodium (DSS) in water for 10 days to induce inflammatory bowel disease. From the fourth day of DSS treatment, the control group was given distilled water only, the MF group was given MF powder in distilled water, and the OMH group was given dried OMH extract powder in distilled water for 7 days. Results: For each animal, changes in body weight, colon length, and component levels in blood and colon tissues after each treatment were noted. The weight in the control group and MF group decreased slightly compared with that in the OMH group, and the colon length in the MF group and OMH group was more than that in the control group. TNF-α and WBC were decreased in both the MF group and the OMH group. RBC was increased in the OMH group, like in the normal group, compared with the control group and MF group. Hb and PLT of each group were not significantly different. Regarding changes in the colon tissues, both the MF group and OMH groups recovered similar to the normal group. Conclusions: Thus, treatment with OMH and MF seems to be effective against inflammatory bowel disease, and OMH is likely to increase body weight and induce RBC recovery better than MF.

  • Objectives : To investigate the effect of electro-acupuncture (EA) at GB34 on hepatotoxicity in $CCl_4$-intoxicated rats. Methods : Rats were injected with $CCl_4$ and treated with acupuncture or 2 Hz electro-acupuncture (EA) at left GB34 three times a week for 10 weeks. A non-acupoint in left gluteal area was selected as a sham point. To estimate the effects of EA on hepatotoxicity in rats, body weight, liver weight and liver index were measured, and biochemical assays for serum ALT, AST, ALP and total cholesterol, and hematological analysis for RBC, WBC, PLT, hemoglobin, lymphocytes, neutrophils and monocytes, and histology analysis of liver tissue were performed. Results : 1. Lymphocyte level in blood was significantly decreased by $CCl_4$-intoxication and significantly increased by acupuncture and 2 Hz EA at left GB34. 2. Neutrophill and monocyte level in blood was increased by $CCl_4$-intoxication and significantly reduced by acupuncture and 2 Hz EA at left GB34. 3. Acupuncture and 2 Hz EA at left GB34 significantly reduced serum ALT and AST which were increased by $CCl_4$-intoxication. 4. EA at GB34 significantly reduced serum ALT and AST as compared with EA at sham point in $CCl_4$-intoxicated rat. 5. No significant difference was found between the effects of acupuncture and that of 2 Hz EA on $CCl_4$-induced liver damage in rats. Conclusions : 2 Hz EA at GB34 has hepatoprotective effects on $CCl_4$-induced liver damage in rats and the point-specificity of GB34 may be involved in these effects.
