Abstract: The aim of this study was to determine the distribution of clinical microorganisms isolated from spontaneous bacterial peritonitis patients. Ascitic fluid was collected from these patients and cultured for pathogens. The patients were placed into three groups, Group A (01/1996 to 12/2000), B (01/2001 to 12/2005) and C (01/2006 to 06/2010) and the clinical data were compared among these groups. There was a significant difference in the ratio of pathogens (Gram- positive bacteria/ isolated pathogens, Gram-negative bacteria/ isolated pathogens) between groups A and C (P < 0.001). Spontaneous bacterial peritonitis patients with Gram-positive bacteria used significantly more antibiotics within 30 days compared to those with Gram-negative bacteria (P < 0.001) . In recent years, the types of isolated pathogens have significantly changed in Northern China. Such changes have also been observed in other countries and have been attributed to long-term antibiotic therapy and invasive procedures. Changes in the epidemiology of pathogens that cause spontaneous bacterial peritonitis must be monitored for optimal treatment.[...] Read More.

Abstract: In order to detect Hepatitis C virus NS3 antigen (HCAg-NS3) in human serum, we developed a magnetic microparticle (MMP) based immunoassay by using biotin-streptavidin amplification, MMP in combination with immunoassay. Results showed that the HCV NS3 monoclonal antibody had a high immobility rate (87.1%) on the surface of MMPs; the assay procedure required smaller volumes of reagents (only 20 l of immune magnetic bead); the detection could be completed within 30 min; this method could detect 10 pg/ml HCAg-NS3 (sensitivity: 5.2 pg/ml) and had favorable stability; the mean coefficient of variances (CVs) of intra-assay and inter-assay were 5.35 and 7.15%, respectively. The results of this method were also related to those in HCV RNA detection with a linear correlation coefficient of 0.570 (P < 0.01). These findings demonstrate this assay which has high specificity, sensitivity, precision and stability may be promising in clinical application.[...] Read More.

Abstract: The principle purpose of this study was to investigate the immunomodulatory ability of three microbial strains isolated from Bama County centenarians in activating macrophages, and to characterize the effective component of these strains. A murine macrophage cell line, RAW264.7, was cultured in presence of intact bacterial cells, bacterial cell wall (CW) or cell free extract (CFE) . NO, IL-6, TNF-production and phagocytic activity of co-cultured macrophages were tested. Bifidobacterium adolescentis BBMN23, Bifidobacterium longum BBMN68 and Lactobacillus saliva Ren were demonstrated to enhance the activities of macrophages by increasing the phagocytic activity and NO, IL-6, TNF- production. The immunomodulatory activities of these microbial strains are mainly due to the CW fraction, although their CFE were also effective. The results of this study indicated that specific substrains of bifidobacterium and lactobacillus from guts of healthy centenarians (Bama County, China) may be of immunomodulatory value, and thus may have the potential to be used as probiotics.[...] Read More.
Keywords: Bifidobacterium, lactobacillus; RAW 264.7 cells, immunomodulatory activities, bacterial fractions.

Abstract: Prostate specific antigen (PSA) is a glycoprotein produced as a marker by prostate gland for prostate cancer, benign prostate hyperplasia and prostatitis. Study objective is to evaluate f/t PSA ratio to distinguish the Benign Prostate Hyperplasia (BPH) and prostate cancer patients in and around SRM University. To define the age specific reference ranges of PSA in control and test group at Chennai, India. Healthy men aged 40 - 75 years in and around SRM Medical College and Research Centre, Chennai, India were selected and grouped as control. Blood samples were collected from patients who attended Cancer Hospital, Adiyar underwent rectal examination revealed prostate enlargement. Results of our study showed that they were diagnosed as BPH and as Cancer, using PSA determination. The free to total PSA ratio were decreased significantly in cancer patients than BPH. PSA was increased linearly with age and observations were associated with the claims of National Academy of Clinical Biochemistry guideline reported that the clinical decisions limits should be decreased for younger patients (age below 50) and should be increased for older patients (age above 50). PSA should be used more appropriately to distinguish (BPH) and prostate cancer and to detect cancer prostate at an early stage. The age specific reference ranges and different forms of PSA have the potential to make serum PSA, a more discriminating tumor marker for detecting cancer prostate significantly in men.[...] Read More.

Abstract: The effect of feeding egusi melon oil as a supplement to a cholesterol-based diet on serum lecithin: cholesterol acyltransferase activity of rats was evaluated. The rats were divided into two groups designated: control and test respectively. Rats in the test group were fed 5% cholesterol diet supplemented with 5% egusi melon oil while the control rats received 5% cholesterol diet without egusi melon oil. After 6 weeks of diet feeding, the enzyme activity was decreased significantly (p < 0.05) in the egusi melon oil- fed rats compared with the control. The test group also showed relative significant decreases in the serum levels cholesteryl ester and lysolecithin (p < 0.05) and increase levels of lecithin (p < 0.05). Significant decreases (p < 0.05) were also observed in serum total and free cholesterol in the egusi melon oil treated group compared to the control group. The implications of these results are discussed with respect to hypercholesterolemia.[...] Read More.

Abstract: The effect of soaking and boiling, and autoclaving on nutritional factors (proximate and mineral) and anti-nutritional qualities of the legume, Mucuna flagellipes were studied. Batches of seeds were soaked for 6, 12, 18 and 24 h in distilled water at room temperature, then boiled in water for 30, 45, 60 or 90 min respectively. Another batch of M. flagellipes was autoclaved for different duration of 30, 45, 90 and 120 min respectively. Results showed that soaking followed by boiling produced products with lower crude fibre content (10% for soaking for 24 h followed by boiling for 90 min). However it increased the carbohydrates. Autoclaving resulted in products with lower mineral contents (1042.5 mg/100 g phosphorous for autoclaving for 120 min.[...] Read More.

Abstract: The leaves of HIBISCUS ROSA-SINENSIS Linn. (Family Malvaceae) have been used in ethnomedicine for the treatment of various human diseases such as aphrodisiac, hypertension, wound healing, diabetes mellitus and cancer. In this present study, the effect of 200 mg/kg of the aqueous leaf extract on the renal function of hypertensive rats was investigated. The administration of H. leaves extract shows a significant (p < 0.05) increase in the Na+ level of normotensive rats, thus it may interfere with the normal function of the kidney and hence produce increased salt retention. These results had shown that although H. ROSA-SINENSIS leave extract reduced blood pressure; the integrity of the kidney may be compromised when this plant is used for the treatment of hypertension.[...] Read More.

Abstract: Two sensitive cultivars were examined, VITTORIA and ITALIA, grafted on a tolerant rootstock (140 Ruggeri). Two levels of iron chlorosis in scions were selected, initial and evident, and compared to the healthy rootstock (control). The fractions of extracellular and cytoplasmatic cations, chloroplastic mobile, loosely linked, strongly linked and residual cations as well as the active fraction were extracted from the fresh matter. In the chlorotic the plant inability to use Fe2+ uptaken by the rootstock was highlighted, with a different response from VITTORIA and ITALIA, as evidenced by the decrease in the available fraction of Fe2+, particularly in the case of evident chlorosis. The increase in leaf content of the active forms of K+ and Ca2+ resulted directly correlated to the intensity of iron deficiency, since they bring about a higher pH and a destabilization of membranes, respectively, both hindering iron utilization. The modified response in terms of reduced photosynthetic activity in chlorotic scions was evidenced through the decrease in the active form of Mg2+ and consequently in chlorophyll content.[...] Read More.
Keywords: Fe and nutrition unbalance, active Fe fraction, iron chlorosis.

Abstract: This research was carried out to assess the effect of hypertension on haemorrheologic and fibrinolytic activities in fifty (50) diabetics resident in Calabar municipality and the values obtained were compared with those of fifty (50) age and sex-matched non diabetics in the same locality. Relative plasma viscosity plasma fibrinogen concentration, euglobulin lysis time and fasting blood sugar were determined using standard methods. The relative plasma viscosity, plasma fibrinogen concentration, euglobulin lysis time and the fasting blood sugar values were significantly higher in diabetics (P < 0.05) when compared with the controls. Correlation between RPV and duration of diabetes was positive and significant (r = 0.323, p < 0.05). Also, correlation between fasting blood sugar and plasma fibrinogen concentration was positive and significant (r = 0.635, p < 0.05).There was no significant increase in RPV, PFC and ELT of type I diabetes when compared with type II diabetes (P > 0.05). The RPV and ELT of diabetics with hypertension was increased, but showed no significant difference (P > 0.05) with that of those who had no hypertension. However, the PFC of diabetics with hypertension was significantly increased (P < 0.05) when compared with that of the control group. The diabetics who were on oral hypoglycaemic agents and insulin showed no significant difference (P > 0.05) in RPV, PFC and ELT when compared with those who were on combination therapy of oral hypoglycaemic agents (glanil, glucophage), but there was significant increase when RPV, PFC and ELT values were compared with the controls (P < 0.05). This work shows that defective rheology and poor fibrin clearing may be the contributory factor to vascular and thrombotic complications seen in diabetics.[...] Read More.

Abstract: Lecithin: cholesterol acyltransferase (LCAT) is a glycoprotein enzyme involves in the esterification of plasma cholesterol to form cholesteryl ester and is important in the maturation of high density lipoprotein. Lipid metabolism in sickle cell anaemia patients may be affected. The objective of this study was to determine the activities of serum lecithin: cholesterol acyltransferase, lipoprotein lipase, lipids and lipoprotein levels in sickle cell anaemia patients in a steady state. The study population consisted of 144 confirmed sickle cell disease patients; 68 males aged 22.2 ± 3.8 years and 76 females aged 21.0 ± 3.0 years. Fifty age matched males; 25 sickle cell trait (HbAS), 25 normal haemoglobin (HbAA) and fifty females; 25 HbAS and 25 HbAA were used as controls. Statistically significant decrease in LCAT and LPL activities (p < 0.001) were observed in sickle cell anaemia patients compared with HbAS and HbAA controls in both sexes. Decrease levels of cholesterol (p < 0.001) and HDL cholesterol (p < 0.001) were also observed in sickle cell anaemia patients. The activities of lecithin: cholesterol acyltransferase and lipoprotein lipase were lower in subjects with sickle cell anaemia than sickle cell trait and normal haemoglobin. This may contribute to the changes observed in lipid metabolism in sickle cell anaemia. The exact cause is not known but appears to be multifactorial.[...] Read More.
