  • The purpose of this study was to investigate the therapeutic effects of DA-9801, an optimized extract of Dioscorea species, on diabetic peripheral neuropathy in a type 2 diabetic animal model. In this study, db/db mice were treated with DA-9801 (30 and 100 mg/kg, daily, p.o.) for 12 weeks. DA-9801 reduced the blood glucose levels and increased the withdrawal latencies in hot plate tests. Moreover, it prevented nerve damage based on increased nerve conduction velocity and ultrastructural changes. Decrease of nerve growth factor (NGF) may have a detrimental effect on diabetic neuropathy. We previously reported NGF regulatory properties of the Dioscorea genus. In this study, DA-9801 induced NGF production in rat primary astrocytes. In addition, it increased NGF levels in the sciatic nerve and the plasma of type 2 diabetic animals. DA-9801 also increased neurite outgrowth and mRNA expression of Tieg1/Klf10, an NGF target gene, in PC12 cells. These results demonstrated the attenuation of diabetic peripheral neuropathy by oral treatment with DA-9801 via NGF regulation. DA-9801 is currently being evaluated in a phase II clinical study.

  • A female French Bulldog was referred to Veterinary Medical Teaching Hospital, Chungbuk National University. In case, alopecia and erythema nodosum were the main complaints in a 16 months old female dog. Ventral alopecia and dorsal erythema nodosum have been presented on skin lesions for 8 months. There were no specific change with CBC and blood chemistry but plasma estrogen concentration was 68 pg/ml and cornified superficial epithelial cells were detected above $90\%$ by cytology examination of vaginal smear preparation. Ovarian cyst was detected by ultrasonography in the left ovary. Cystic diameter was $14.2\times12.0mm$. Therefore, we diagnosed as unilateral multiple follicular cysts. The dog was treated with GnRH $50{\mu}g$ injection by intramuscularly Cyst size was decreased $7.3\times7.2mm$ after 7 days GnRH treatment and disappeared after 14 days GnRH treatment. Also dermatitis by unilateral multiple follicular cysts were recovered after 21 days GnRH treatment.

  • Statins are competitive inhibitors of hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase and used most frequently to reduce plasma cholesterol levels and to decrease cardiovascular events. However, statins also have been reported to have undesirable side effects such as myotoxicity and hepatotoxicity associated with their intrinsic efficacy mechanisms. Clinical studies recurrently reported that statin therapy elevated the level of liver enzymes such as ALT and AST in patients suggesting possible liver toxicity due to statins. This observation has been drawn great attention since statins are the most prescribed drugs and statin-therapy was extended to a larger number of high-risk patients. Here we employed rat primary hepatocytes and microarray technique to understand underlying mechanism responsible for statin-induced liver toxicity on cell level. We isolated genes whose expressions were commonly modulated by statin treatments and examined their biological functions. It is of interest that those genes have function related to response to stress in particular immunity and defense in cells. Our study provided the basic information on cellular mechanism of statin-induced cytotoxicity and may serve for finding indicator genes of statin -induced toxicity in rat primary hepatocytes.

  • In this study, we cloned, sequenced and characterized porcine y+L Amino Acid Transporter-1 (y+LAT1). By screening a translated EST database with the protein sequence of the human $y^{+}$LAT1 and by using rapid amplification of cDNA ends (RACE), the full-length cDNA encoding porcine $y^{+}$LAT1 was isolated from porcine intestine RNA. It was 2,111 bp long, encoding a 511 amino acid trans-membrane glycoprotein composed of 12 transmembrane domains. The predicted amino acid sequence was found to be 91%, 90%, 87% and 87% identical to those of cattle, human, mouse and rat $y^{+}$LAT1 respectively. Real-time RT-PCR results indicated that the small intestine had the highest $y^{+}$LAT1 mRNA abundance and the lung had the lowest $y^{+}$LAT1 mRNA abundance. Baby hamster kidney (BHK) cells transfected with green fluorescent protein (GFP) tagged porcine $y^{+}$LAT1 cDNA indicated that the cellular localization of the gene product in BHK was on the plasma membrane.

  • In this study, we demonstrated selenium (Se) accumulation in Bifidobacterium longum strain (B. longum) and evaluated the effect of Se-enriched B. longum (Se-B. longum) on tumor growth and immune function in tumor-bearing mice. Analysis using high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS) revealed that more than 99% of Se in Se-B. longum was organic, the main component of which was selenomethionine (SeMet). In the in vivo experiments, tumor-bearing mice (n=8) were orally administrated with different doses of Se-B. longum alone or combined with cyclophosphamide (CTX). The results showed that the middle and high dose of Se-B. longum significantly inhibited tumor growth. When Se-B. longum and CTX were combined, the antitumor effect was significantly enhanced and the survival time of tumor-bearing mice (n=12) was prolonged. Furthermore, compared with CTX alone, the combination of Se-B. longum and CTX stimulated the activity of natural killer (NK) cells and T lymphocytes, increasing the levels of interleukin-2 (IL-2) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and the leukocyte count of H22 tumor-bearing mice (n=12).

  • In two separate experiments with crossbred bulls (Sahiwal $\times$ indigenous) the effect of access to a urea-molasses lickblock (MOL-U-MIN) on straw diets was studied. The animals were given either untreated (US) or urea treated (TS) rice straw with or without lickblock supplementation. In experiment 1, individual dry matter intake (DMI) and dry matter digestibility (DMD) were measured, while in experiment 2 in addition to the above rumen (pH, ammonia, minerals) and blood (protein, minerals and haemotological) parameters were also measured. With both experiments urea treatment did not effect DMI, but lickblock supplementation significantly (p < 0.05) increased DMI. The DMD values obtained in both experiments for TS were significantly (p < 0.05) higher than for US, but lickblock supplementation did not effect the DMD of either US or TS fed animals. Both urea treatment (6.97 vs 6.93) and lickblock supplementation (6.98 vs 6.92) significantly (p < 0.001) reduced the rumen pH. Urea treatment and lickblock supplementation increased the rumcn $NH_3-N$ concentration (mg/100 ml) from 8.7 to 11.9 and 9.2 to 11.4, respectively. Both US and TS diets fed with or without lickblock increased the molar ratio of Na : K in saliva. Phosphorus content in blood plasma was significantly (p < 0.01) increased due to lickblock supplementation, whereas the Fc content in blood was significantly increased (p < 0.01) by urea treatment. Haemoglobin content in blood ranged from 11.3 to 11.7 g/dl, and was not influenced by urea treatment or lickblock supplementation. Lickblock significantly reduced the number of red blood cells, but increased the mean corpuscular volume. It is concluded that feeding urea treated straw with proper mineral supplementation could be a more economical alternative to lickblock supplementation.

  • Background: Symptomatic multiple myeloma (MM) is an acquired B-cell malignant proliferation of antibody secreting plasma cells, characterized by end organ damage due to monoclonal immunoglobulin secretion. The aim of this study wa to determine the stage stratification according to an international scoring system in adult Pakistani MM patients at presentation. Materials and Methods: This single centre retrospective study extendedfrom January 2012 to December 2015. Data were retrieved from the departmental maintained records. Results: A total of 39 patients were diagnosed at our center with MM during the period of the study, 25 males and 14 females. Age ranged between 36 and 81 with a mean of $54.5{\pm}14.8$ and a median of 57 years. Common presenting complaints included fatigue (80.9%), backache (79.3%) and bone pain (66.2%). Overall, 9 patients were in ISS stage I (23%), 12 were in stage II (30.7%) and 18 were in stage III (46.1%). Out of the total, 29 (74.3%) had kappa immunoglobulin andthe remaining 10 (25.6%) had lambda type myelomas. IgG myeloma was commonest, seen in 26 (66.6%) followed by IgA in 11 (28.2%) with non secretory myeloma in one (2.5%) and light chain disease also in one patient (2.5%). Conclusions: MM in Pakistani patients is seen in a relatively young population with male predominance. Primarily patients are symptomatic and risk stratification revealed a predominance of advanced stage III disease in our setting.

  • Hand, foot, and mouth disease (HFMD) is an acute, mostly self-limiting infection. Patients usually recover without any sequelae. However, a few cases are life threatening, especially those caused by enterovirus 71 (EV71). A 12-month-old boy was admitted to a primary hospital with high fever and vesicular lesions of the mouth, hands, and feet. After 3 days, he experienced 3 seizure episodes and was referred to our hospital. On admission, he was conscious and his chest radiograph was normal. However, 6 hours later, he suddenly lost consciousness and had developed a massive pulmonary hemorrhage that continued until his death. He experienced several more intermittent seizures, and diffuse infiltration of both lung fields was observed on chest radiography. Intravenous immunoglobulin, dexamethasone, cefotaxime, leukocyte-depleted red blood cells, fresh frozen plasma, inotropics, vitamin K, and endotracheal epinephrine were administered. The patient died 9 hours after intubation, within 3 days from fever onset. EV71 subgenotype C4a was isolated retrospectively from serum and nasopharyngeal swab by real-time reverse transcription-polymerase chain reaction. Here, we report a fatal case of EV71-associated HFMD with sudden-onset massive pulmonary hemorrhage and suspected encephalitis.

  • The performance of naked neck and normal chicken was evaluated with respect to growth, carcass, immune, biochemical and stress parameters under winter and summer seasons to assess the suitability of naked neck birds under high temperatures in the global scenario of climate change. The growth performance was significantly ($p{\leq}0.05$) higher in naked neck chicken in the summer season. The dressing percentage was significantly ($p{\leq}0.05$) higher in naked neck birds in both winter and summer season because of reduced plumage. The thigh, giblet and feather proportion significantly ($p{\leq}0.05$) varied between naked neck and normal chickens in summer season. The humeral immune response to sheep red blood cells (SRBC), Newcastle disease vaccine (NDV) and cutaneous basophil hypersensitivity (CBH) did not show any significant differences among the chicken groups. The protein and cholesterol concentration observed was within the normal ranges. The total cholesterol levels in plasma were significantly ($p{\leq}0.05$) lower in naked neck birds in both the seasons. H:L ratio was significantly ($p{\leq}0.05$) lower in summer season indicating less stress in naked neck chicken. Basophil and eosinophil concentration was significantly ($p{\leq}0.05$) higher in normal chicken in summer. The lipid peroxidation was higher in full feathered birds under summer stress. The enzyme glutathione reductase (GR) levels were significantly higher during the summer and varied significantly ($p{\leq}0.05$) between the normal and naked neck chicken in both seasons. The results indicated that the naked neck birds performed significantly better at high ambient temperatures with respect to growth, carcass and biochemical parameters. It was concluded that the ability of the naked neck chicken to adapt to high temperatures foresees a viable option for the biological mitigation of climate change.

  • As fat consumption has increased in Korea , serum cholesterol concentrations have risen and the prevalence of atherosclerosis increased. The aim of the present study was to investigate the association among apolipoprotein E (Apo E) phenotypes, dietary fat consumption, plasma lipoprotein levels and fatty acid compositions of red blood cells in young healthy women. Seventy-one percent of participants had Apo E3/3, 14.9 percent had ApoE3/2 , 11.8% had Apo E4/3 and 1.2% had Apo E4.2. The subjects daily consumed approximately 1760kcal containing 29 energy % of fat. The ratio of polyunsaturated fat to saturated fat in a diet was 0. 73 . There were no significant differences of nutrient intakes according to Apo E phenotypes. Total cholesterol concentrations of subjects averaged approximately 160mg/dl , but 12 percent of them had over 200mg/dl, which is higher than the range recommended by the National Cholesterol Deucation Program. Notably, most subjects with 210mg/dl had Apo E4 isoforms. Subjects with Apo E4 isoforms had significantly higher total and LDL-cholesterol concentrations than those with Apo E3/2. Also subjects carrying Apo E4 isoforms tended to accumulated more fat in the body. Their BMI , WHR and arm fat area appeared to be how can arm fat area be greater no you mean grater, please check work vsage than subjects with Apo E3 isoforms, but not significantly. Fat intakes slightly influenced serum cholesterol levels. Myristic aicd intakes were positively correlated to serum total and LDL-choelsterol levels. Polyunsaturated fatty acid intakes were negatively correlated to serum total choelsterollevels. The results of 소냐 study suggest that , people with Apo E4 isoforms need to prevent the raising of serum total and LDL -cholesterol concentrations by reducing calorie and fat intakes and by maintaining a normal weight.
