This was conducted to determine the effects of body weight, organ weight, hematological values and biochemical parameters by L-carnitine (Carn) on the orchidectomized (Orch) rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. Orch group received operation and no treatment. Orch+Carn received operation and L-carnitine. The body weights of each group increased, but that of the Orch+Carn group were significantly lower than those in all the other groups. There were significant differences (P<0.05, P<0.001) of body weights between Orch+Carn group and all the other groups. Also, organ weights such as heart, liver, spleen and kidney were measured. The heart weights were significantly lower (P<0.001) in the Orch+Carn group than those in Intact and Sham groups, respectively. The weights of liver and kidney in the Orch+Carn group were significantly differences (P<0.001) in comparison with those in all the other groups. Also, the spleen weights were significantly lower (P<0.05) in the Orch+Carn group than those in Intact and Sham groups, respectively. The hematological values of mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were significantly differences (P<0.05, P<0.01, P<0.001) in comparison with those in all the other groups. On the other hand, the hematological values of white blood cell (WBC), red blood cell (RBC) and mean corpuscular hemoglobin concentration (MCHC) were not significantly different in any other groups. The concentrations of total cholesterol (T-chol), triglyceride (TG) and high density lipoprotein (HDL) decreased significantly (P<0.05) in the Orch+Carn group as compared to those in the Orch group. We conclude that L-carnitine was significantly decreased the body weight in the orchidectomized rats. Our findings suggest that L-carnitine may influence the process of lipid packaging and absorption in the orchidectomized rats.

Although various automated CBC analyzers with different WBC analytical principles were consequently introduced to clinical laboratory, the specific information concerning the suitability or unsuitability of aging samples is scarce. For this reason, we studied the effect of storage duration and temperature on CBC parameter in SE-9000 (SYSMEX Medical Electronics Co., Ltd., Kobe, Japan), automated CBC analyzer. We tested 32 K3-EDTA specimens with SE-9000 during 72 hours. Specimens were kept at room temperature (RT) and refrigerated and were analyzed at 0 hr, 4 hr, 8 hr, 24 hr, 48 hr and 72 hr after the collection of the specimens. The percentage changes from initial value for each parameters were calculated. Among the CBC parameters, hemoglobin, red blood cell count, mean corpuscular hemoglobin and platelets were stable for the study period at both temperatures. The mean corpuscular volume (MCV), hematocrit (Hct) and red cell distribution (RDW) increased and the mean corpuscular hemoglobin concentration (MCHC) decreased over time at room temperature. These parameters were stable when refrigerated. The leukocyte count was stable during 72hr at RT and when refrigerated. At room temperature, the relative percentages of neutrophils tend to increase, whereas those of lymphocyte and monocytes tend to decrease after 48 hours. When refrigerated, those of neutrophils and monocytes tend to increase, whereas those of lymphocytes tend to decreased over time. CBC parameters of refrigerated specimen were reliable for 72 hr for the exception of differential count from 24 hr but many CBC parameters, such as MCV, Hct, MCHC, RDW and differential count of leukocyte of blood stored at room temperature for 24 hr were unreliable.

Background: Capecitabine is an oral fluoropyrimidine derivative which is frequently used alone or in combination regimens for the treatment of metastatic breast cancer. Although overall and progression free survivals have increased in recent years with the use of new generation drugs, predictive factors that would further improve the outcomes are needed. Previous studies have demonstrated the relation between post-treatment increase in mean corpuscular volume (MCV) and predicting therapy response as well as survival. The present study investigated the clinical impact of MCV elevation in metastatic breast cancer patients treated with capecitabine. Materials and Methods: The data of a total of 82 patients from three centers followed between June 2005 and June 2013 were retrospectively analyzed. The demographic data and hormone receptor status of the patients, as well as initial examination before and after treatment and data concerning progression were recorded. MCV ${\geq}100$ fl was considered as macrocytosis. Capecitabine was given at a dose of $2500mg/m^2$ daily for 14 days every three weeks. Pre-treatment and post-treatment MCV and other parameters of complete blood count were recorded. Post-treatment initial evaluation was performed after 2 cycles of therapy. Results: The median age of the patients was 46.5 years (range 26-72 years) and 54% were premenopausal. Performance status was ECOG 0 and 1 in 81 (99%) patients. The median number of cycles for capecitabine therapy was 5 (min-max: 2-18). The median ${\Delta}MCV$ level (post-treatment values at sixth week - baseline) was 6.4. Whilst ${\Delta}MCV$ was ${\geq}6.4$ in 42 patients, it was <6.4 in 40 patients. Clinical benefit (complete response+partial response+stable disease) was observed in 37 (88%) of 42 patients with a median ${\Delta}MCV$ ${\geq}6.4$ and in 30 (75%) of 40 patients with ${\Delta}MCV$ <6.4 with no statistically significant difference (p=0.158). No significant difference was determined between the group with ${\Delta}MCV$ ${\geq}6.4$ and the group with ${\Delta}MCV$ <6.4 in terms of progression-free survival (11 vs 12 months) (p=0.55) and overall survival (20 months vs. 24 months) (p=0.11). Conclusions: The identification of new predictive markers in metastatic breast cancer is very important. In some recent studies, increase in MCV has been suggested as a marker in tumor response. In the present study, however, no significant difference was determined between tumor response and increase in MCV. Further studies including higher numbers of patients are needed to determine whether increase in MCV is a predictive marker or not.

This study was conducted to investigate changes in blood properties of high potassium (HK) phenotype Jindo dogs (15kg$\pm$2kg) after daily oral administration with water celery extracts (10 ml/kg) for 7 days. Blood samples were collected for three days in a row before administration of water celery extracts. After water celery extracts administration, blood samples were collected at 3h, 6h, 9h and then on daily basis until day 10 post administration (PA). At day 15, final sample was collected. Blood samples were analyzed on the basis of red blood cell (RBC), white blood cell (WBC), packed cell volume (PCV), hemoglobin (Hb) concentration, mean corpuscular volume(MCV), mean corpuscular hemoglobin concentration(MCHC), gluthathione concentration(GSH) and met-hemoglobin(Met-Hb) concentration. The significant changes (p<0.01, p<0.05) of RBCs were shown at 3 h to day 5, and days 7 and 9 after administration. PCV values were decreased form 3 h to day 10 after administration. Mean Hb concentration showed significant increase as 3 h to day 3, and day 6 to day 9 after administration. The significant changes (p<0.05) of WBCs were shown at 9 h and day 1 after administration. The increased numbers of MCV were detected at days 6 to 9 after administration (p<0.05, p<0.01). The significant changes of MCHC were shown at 9h and day 1 after administration. The significant increases (p<0.01, p<0.05) of GSH concentration were detected at days 1, 6 and 7 after administration. In Met-Hb concentration, the significant increases (p<0.05) occurred at only 9h and day 7 after administration, The significant increases (p<0.01, p<0.05) of reticulocyte were detected at days 2, 4, 5, 6 and 7. Data from blood samples collected at day 15 after administration showed that all of blood analysis results returned to normal level, compared to controls.

Iron deficiency anemia (IDA) is the world's most common nutritional problem. It is characterized by a low hemoglobin (Hb) level and low iron status. A study was conducted to investigate the incidence of iron deficiency anemia in day scholar girls belonging to different socioeconomic strata at Punjab University, Lahore. Iron status of the subjects was estimated by measuring Hb, hematocrit (Hct), red blood cell (RBC) count, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCR), serum iron, serum ferritin, total protein and albumin. Results indicated that females belonging to low socioeconomic strata had lower values for Hb, Hct, RBC count, total protein and albumin. Serum iron, serum ferritin, MCV and MCH values fell within the normal range for all of the socioeconomic groups. However, serum iron and ferritin varied with socioeconomic status and higher-income groups had significantly higher serum iron and ferritin. It was concluded that anemia may develop due to poor intake and absorption of iron and that those in the low-income bracket are the most affected group.

We have developed the tablet formulation of Triticum aestivum (wheatgrass) and investigated clinically, its effects in patients suffering from b-thalassemia (major) at K. T. Children Hospital, Civil Hospital, Rajkot. The tablets (wheatgrass powder 250 mg.) were given 3 times in a day for 9 months. Blood samples were collected at the start, after 6 months and 9 months and analyzed for various biochemical and hematological parameters. Treatment with wheatgrass formulation for 9 months produced significant decrease in hemoglobin, total RBC, eosinophil and reticulocyte counts. The mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) were significantly increased was significantly increased. The serum ferritin was also significantly decreased. There was no influence on serum magnesium, serum iron and Thiobarbituric acid reacting substances (TBARS). Our data indicate that treatment with wheatgrass on patients with $\beta$-thalassemia (major) may have beneficial effects in the form of a decrease in ineffective erythropoiesis, stimulation of hemoglobin synthesis in RBC, decrease in iron load and decrease in eosinophil count.

Progressing to the iron deficiency anemia was experimentally induced in 4 clinically healthy dogs by repeated phlebotomy to characterize hematologic features, serum iron values, and RBC indices. Abnormal RBC morphologies were also evaluated semiquantitatively on Wright's-stained blood films. Hematologic abnormalities in early stage of anemia included decreased both hematocrit and hemoglobin, and reticulocytosis, with no changes in mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) were represented. In intermediate stage, decreased serum iron concentration with microcytosis and hypochromia were prominent. In late stage, red cell distribution width and Mentzer's index were out of reference ranges in the majority of dogs. In this study microcytic anemia was appeared at the hemoglobin range of 5.1-7.2 g/dl. On most sampling days, platelet counts and white blood cells were within the reference ranges, with some minor variations. Iron deficiency was not necessarily associated with microcytic anemia. Judging from the sequential changes of both MCV and MCHC, 3 patterns of anemia were sequentially observed: initially normocytic normochromic, intermediate normocytic hypochromic or normocytic normochormic, and finally microcytic hypochromic. The most frequent morphologic abnormalities were target cells. Occasional elliptocyte, acanthocyte, stomatocyte, kinzocyte, dacrocyte and schistocyte were also noted on the blood films.

Erythrocyte sedimentation rate (ESR) evaluation is a useful tool for monitoring disease activity in various inflammatory and non-inflammatory conditions. ESR is known to be influenced by a multitude of confounding factors. The present study aimed to assess the possible determinants of the ESR and its relationship with various risk factors involved in ischemic stroke. ESR and other hematological and biochemical parameters were investigated in 163 ischemic stroke patients (107 males and 56 females) selected based on imaging techniques including magnetic resonance imaging (MRI) or computed tomography (CT) scans. Statistical analysis was performed using the SPSS 16.0 software. Linear regression analysis showed a significant inverse relationship of hemoglobin (Hb) and hematocrit or packed cell volume (PCV) (P<0.001 for females; P<0.01 for males) with the ESR. It was observed that the red blood cell (RBC) count was not strongly correlated with the ESR (P<0.05 for both males and females). It was also observed that sex significantly affected the variables determining the ESR levels, whereas age had no effect. Gender differences were also observed with respect to Hb, RBC, PCV, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and ESR. The possible determinants of higher ESR levels in ischemic stroke may be sex, Hb, hematocrit, and RBC count, but the role of other clinical and laboratory parameters cannot be underestimated.

Objectives : Biochemical markers can provide an objective evidence of heavy alcohol drinking. The purpose of this study was to compare and evaluate the usefulness of biological markers detecting alcohol dependence, such as mean corpuscular volume(MCV), gamma-glutamyl transferase(GGT), and carbohydrate-deficient transferrin(CDT) in the patients of an alcohol counseling center. Methods : This study was done with 64 patients with alcohol dependence and 36 healthy subjects. Relative values(%) of CDT were determined in their sera with turbidimetric immunoassay(Bio-Rad %CDT assay, Axis-Shield ASA, Oslo, Norway), and were compared with conventional markers of alcohol consumption, GGT and MCV. Results : Among the patients with alcohol dependence, 78.1% showed abnormal %CDT levels compared with GGT(61.9%) and MCV(20.7%). The areas under the receiver operating characteristic(ROC) curves(95% confidence interval) for %CDT, GGT, and MCV were 0.934(0.866-0.973), 0.871(0.789-0.930), and 0.575 (0.472-0.673), respectively. Conclusion : %CDT seems to be the most reliable biological marker for the detection and monitoring of alcohol consumption in the patients with alcohol dependence of the alcohol counseling center.
