  • Objective: To explore the immune reconstitution of $CD4^+T$ cells after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and its relationship with invasive fungal infection (IFI) in patients with hematological malignancies. Materials and Methods: Forty-seven patients with hematological malignancies undergoing Allo-HSCT in Binzhou Medical University Hospital from February, 2010 to October, 2014 were selected. At 1, 2 and 3 months after transplantation, the immune subpopulations and concentration of cytokines were assessed respectively using flow cytometry (FCM) and enzyme linked immunosorbent assay (ELISA). The incidence of IFI after transplantation and its correlation with immune reconstitution of $CD4^+T$ cells were investigated. Results: The number of $CD4^+T$ cells and immune subpopulations increased progressively after transplantation as time went on, but the subpopulation cell count 3 months after transplantation was still significantly lower than in the control group (p<0.01). In comparison to the control group, the levels of interleukin-6 (IL-6) and IL-10 after transplantation rose evidently (p<0.01), while that of transforming growth factor-${beta}$ (TGF-${beta}$) was decreased (p<0.01). There was no statistically significant difference level of interferon-${\gamma}$ (IFN-${\gamma}$) (p>0.05). The incidence of IFI was 19.2% (9/47), and multivariate logistic regression revealed that IFI might be related to Th17 cell count (p<0.05), instead of Th1, Th2 and Treg cell counts as well as IL-6, IL-10, TGF-${beta}$ and IFN-${\gamma}$ levels (p>0.05). Conclusions: After Allo-HSCT, the immune reconstitution of $CD4^+T$ cells is delayed and Th17 cell count decreases obviously, which may be related to occurrence of IFI.

  • Background: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric age group. All patients with RMS regardless of their initial stage or group receive combination chemotherapy as 'standard therapy' consisting of vincristine, actinomycin-D and cyclophosphamide. Actinomycin-D was not readily available in Turkey at one time. Carboplatin was used instead in order to prevent delays in treatment. The aim of this report is to present the results of patients with rhabdomyosarcoma receiving carboplatin or actinomycin-D therapy. Materials and Methods: Twenty four patients with rhabdomyosarcoma treated between December 2000 and June 2011 were included in this retrospective study. The patients were treated according to International Rhabdomyosarcoma Study Group guidelines. Eleven patients were treated with actinomycin-D and 13 with carboplatin ($250mg/m^2/dose$ for 2 days). The two groups were then compared in terms of 2- and 5-year overall survival (OS) and hematological and non-hematological toxicities. Results: Age, sex, stage and the mean duration of follow-up were similar in both groups (p>0.05). Two- and five-year OS levels were 68.2% in the carboplatin group and 78.0% and 40.0%, respectively, in the actinomycin-D group. There was no statistical difference in the number of febrile episodes (p=0.86) and no other hematological and non-hematological adverse effects were recorded in both groups. Conclusions: The findings show that carboplatin can be used as an alternative drug in the primary treatment of rhabdomyosarcoma in the event that actinomycin-D is unavailable or not tolerated.

  • Objective: To investigate the efficacy and safety of voriconazole in treating Chinese patients with hematological malignancies and invasive aspergillosis. Methods: From March 2007 to April 2012, patients with diagnoses confirmed by CT, GM test and/or PCR assays, were recruited into this study. Aspergillosis of all patients were treated with voriconazole 6 mg/kg intravenous infusion (iv) every 12 h for 1 day, followed by 4 mg/kg IV every 12 h for 10-15 days; Then, switch to oral administration that was 200mg every 12h for 4-12 weeks. Efficacy and safety were evaluated according to Practice Guideline of Infectious Diseases Society of America. Results: The overall response rate of 38 patients after voriconazole treatment was 81.6%. The median time to pyretolysis was 4.5 days. Treatment related side effects were mild and found in only 15.8% of cases. No treatment related deaths occurred. Conclusions: Voriconazole can considered to be a safe and effective front-line therapy to treat patients with hematological malignancies and invasive aspergillosis. Alternatively it could be used as a remedial treatment when other antifungal therapies are ineffective.

  • Flatfish Paralichthys olivaceus raised in biofloc system (mean length $27.6{\pm}3.1cm$, mean weight $280.4{\pm}26.5g$) were exposed for to different concentrations of ammonia (0, 8, 16, 32, and $64mg\;{NH_4}^+/L$) for 7 days. Following ammonia exposure, hematological parameters such as hemoglobin and hematocrit were significantly reduced. Plasma components such as magnesium, glucose, aspartate aminotransferase (AST), and alanine aminotransaminase (ALT) were significantly altered by ammonia exposure, whereas there were no significant changes in calcium, cholesterol, or total protein. Antioxidant responses, such as superoxide dismutase (SOD) and catalase (CAT) levels were significantly elevated following ammonia exposure. The results of this study indicate that ammonia exposure induces significant changes in hematological parameters and antioxidant responses in biofloc-reared Paralichthys olivaceus as a toxic response.

  • Transporter associated with antigen presenting (TAP) 1 and TAP2 genes are localized in the major histocompatability complex (MHC) class II region and form a heterodimer playing a key role in endogenous pathways for antigen presentation. Defects of these genes have been reported to be common in different types of cancer. Polymorphisms identified in these loci have also been investigated and reported to be associated with several autoimmune disorders, viral infections and neoplasms. In the present study, for the first time, the allele and genotype frequencies of TAP1-333, TAP2-565, TAP2-651 and TAP2-665 were determined in patients with hematological malignancies (HM) using a PCR-RFLP method and compared with the frequencies in the control group. Our results suggested an association of TAP1-333 polymorphism with multiple myeloma-MM and TAP2-565 polymorphism with chronic lymphoid leukemia-CLL. In addition, it could be concluded that the TAP2-665 GG genotype might be a risk factor for all types of hematological malignancies included in this study.

  • This research analyzed the hematological index and health related habits such as alcohol drinking, smoking and exercise, by classifying 539 middle-aged men (age: 40 - 59) into a normal weight group, an overweight group and an obese group, according to BMI (body mass index). As a result, 33.6% (n = 181) of subjects had a BMI of 23 or less and 30.2% (n = 163) were overweight and 36.2% (n = 195) were obese (BMI > 25). The average systolic/diastolic blood pressures of total subjects were 130.96mmHg and 80.38mmHg, respectively. And the average pressure of normal subjects was 126.85/77.57mmHg, which was significantly lower than in overweight and obese subjects. Diastolic blood pressure shows significant differences among the three groups. The overall average cholesterol level of normal subjects was 193.81mg/dl, which was significantly lower than those in overweight subjects. Those in obese subjects were significantly higher than in overweight subjects. The GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrutic transaminase), ${\gamma}$-GTP (gamma-glutamyl transpeptidase) levels of obese subjects were significantly higher than in the overweight subjects. Frequency of alcohol drinking showed no significant difference among the groups. The smoking ratio in the obese group was higher than in the normal and overweight groups. The ratio of smokers was 53.1 %, and the alcohol drinking ratio was 81.0% of the total subjects. The frequency of drinking showed significant correlations with systolic blood pressure (p < 0.05) and diastolic blood pressures (p < 0.01) and ${\gamma}$-GTP (p < 0.01). The duration of smoking showed a negative correlation (p < 0.01) with diastolic blood pressure, total cholesterol and ${\gamma}$-GTP. On the other hand, exercising frequency showed negative correlations with blood glucose, ${\gamma}$-GTP and GPT(p < 0.01). These hematological indices were correlated with health related habits such as alcohol drinking, smoking and lack of exercise, and to be the cause of chronic diseases. Therefore, proper nutritional education is needed to establish advisable health related habits to maintain proper body weight. (J Community Nutrition 8(2): 63-68, 2006)

  • The purpose of this study was to compare food behaviors, nutrient intake, clinical symptoms, and hematological findings by smoking status. Among the third grade male students from a high school in Jinchun-kun, 31 smokers and 31 nonsmokers participated in this study. A self-administered questionnaire was used to investigate food behaviors and clinical symptoms. Nutrient intake data were collected by 24-hour recall method. Blood sample was drawn from each subject to determine the levels of hemoglobin, protein, triglyceride, cholesterol, etc. The major findings were as follows; First, smokers consumed every food group except fat & oil less frequently than nonsmokers, while they consumed instant food, coffee, alcoholic beverages more frequently than nonsmokers. Dietary habits of smokers such as regularity, balanced diet, skipping meals were worse than those of non-smokers. Second, intakes of energy, fat, carbohydrate, and β-carotene of smokers were lower than those of non-smokers. Third, smokers felt fatigue and other adverse symptoms more often than non-smokers. Fourth, the levels of hemoglobin, albumin and HDL-cholesterol were significantly lower in smokers than non-smokers. Fifth, Smoking history was negatively correlated with food behaviors, energy intake and clinical symptoms. These results suggest that food behaviors, nutrient intakes, hematological findings and clinical symptoms of male high school students were affected by smoking. Therefore, in order to decrease smoking rate of the students, the effect of smoking on nutritional and health status should be informed and nutrition education should be offered to the students.

  • This study aimed to identify the effect of brown rice-vegetable school meals program on the subjective health status, BMI and hematological parameters of high school students. This is a single group pre-post study design that includes 17 high school boys and 18 high school girls. Students were catered for lunch and dinner with brown rice and a vegetarian diet for 12 weeks at the school. The collected data on subjective health status, BMI levels and hematological parameters were measured in pre and post, and changes were compared by paired t-test. Subjective health status of the participants has improved and BMI was reduced. Blood Hct, Hb, Hct, total protein and albumin have also been reduced. Ca and triglyceride levels decreased in females. However, all levels were reduced within the normal range. These results show that brown rice-vegetable intake of high school students reduces weight and helps them prevent from acquiring cardiovascular diseases in adulthood through the reduction of serum triglyceride and in practicing healthy eating habits.

  • We examined the effects of the vibration stress on cortisol secretion and hematological characteristics in soft-shelled turtle, Pelodiscus sinensis. For the stressed group vibration of $45{\sim}78 dB(V)$ from electric vibrator applied for 30 min with 2-h intervals during daytime ($08:00{\sim}18:00$) up to 28 days. Using the blood samples collected from ten turtles held once a week after vibration stress, we measured hematocrit, hemoglobin, red blood cells, cortisol, glucose, lactic acid, osmolality, $Na^+,\;K^+,\;Cl^-$, aspartate aminotransferase (AST), and alanine aminotransferase (ALT). The results have showed that P. sinensis received vibration stress exhibit the 'typical' stress-induced physiological responses (cortisol, glucose, lactic acid, osmolality, ions, hematocrit and hemoglobin) induced by vibration stress. Our data suggested that chronic vibration stress caused substantial stress in the animal, and in particular, the persisting elevated levels of AST and ALT would be highly correlated with the adverse effects of the stress. The high hematological characteristics during entire experimental period showed that the P. sinensis could not adapt to chronic stimuli provoked by vibration stress.

  • Aging triggers cellular and molecular alterations, including genomic instability and organ dysfunction, which increases the risk of disease in mammals. Recently, due to the markedly growing number of aging dogs in the world, as much as 49% in total number of pet dogs, it is necessary to improve and maintain their quality of life by understanding of the biological effects of aging. Therefore, the aim of this study was to determine specific biomarkers in aging dogs as a means of defining a set of hematological/biochemical biomarkers that influence the aging process. Blood samples were collected from younger (1-3 years) and older (7-10 years) dogs of middle/large size. The hematological/biochemistry analysis was performed to evaluate parameters significantly associated with age. Enzyme-linked immunosorbent assay was used to target growth hormone (GH)/insulin growth factor-1 (IGF-1), one of the main regulators of the aging process. Declining levels of total protein and increased levels of glucose in young dogs was observed regardless of their body size. Notably, a significantly high concentration of GH and IGF-1 in the younger dogs compared to the older dogs was found in middle/large-sized dogs. GH and IGF-1 were also found at significantly high levels in large-sized dogs compared to middle-sized dogs, suggesting a similar trend to that of elderly humans. Consequently, glucose, total protein, GH, and IGF-1 were identified as potential biomarkers for regulating the aging process in large/middle-sized dogs. These findings provide an invaluable insight into the mechanism of aging for the field of aging research.
