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.

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.

Abstract: The hepatoprotective effect of aqueous extract of Garcinia kola (AEGK) was studied in 60 mice of mixed sexes. The animals were divided into 6 groups of 10 mice each. Group I received normal saline, groups and III got 100 and 200 mg/kg AEGK (orally), respectively. Group IV received 10 mg/kg methamphetamine (MAM) (s.c.) only. Groups V and VI got 100 and 200 mg/kg of AEGK respectively, before 10 mg/kg methamphetamine which was used to induce neurotoxicity. The serum levels of AST, ALT, ALP, total bilirubin and its conjugated metabolite were used to assess liver damage. Fifty percent of the animals in group IV died. 30% died in group V and none in group VI after 10 - 30 min interval of MAM administration. The serum levels of some of the marker enzymes and bilirubin were decreased significantly in groups VI at 200 mg/kg of AEGK (P < 0.05). The Blood glucose level increased transiently in the MAM treated groups. There was a slight rise in serum WBC after an initial fall at 100 mg/kg AEGK. The results suggest a possible hepatoprotective potential of AEGK. This may justify their local use in the management of some hepatic dysfunction and stress-related conditions.[...] Read More.

Abstract: Concomitant production of amylase and protease by Aspergillus awamori nakazawa MTCC 6652 was enhanced in a single fermentation by media engineering and optimization of other important parameters. Wheat bran was considered as a suitable substrate for production of amylase and protease by A. awamori in a single fermentation as none of the additional substrate such as powder of peanut, corn, soybean seeds and sunflower seeds was effective in enhancing the concurrent production of enzymes further. Optimum amylase yield of 4528.4 ± 121U/gds and protease yield of 250.4 ± 10 U/gds was achieved with wheat bran to Czapek-dox ratio of 1:1.5 (w/v), 96 h incubation, 35˚C temperature, pH 5.5 and 85% relative humidity. Media engineered with 1% casein and 1% starch solution increased yield of amylase and protease by 2.07 fold (9386.5 ± 101 U/gds) and 3.73 fold (934.8 ± 67 U/gds), respectively, therefore, considered as the most suitable media for concomitant production of amylase and protease by A. awamori in a single fermentation.[...] Read More.

Abstract: The concern for the development of hyphomycete fungi as suitable biocontrol agents of insect pests leads to the isolation of various insect pathogenic fungi. Amongst them, one of the most studied entomopathogenic fungus is Beauveria bassiana. The conidia of mitosporic fungi adhere to the host cuticle and germinate to produce an infectious propagule, and produce a sequential release of extra cellular enzymes to breach the insect cuticle. Protease is one of the most important and earliest enzymes involved in the host invasion. Extracellular protease production by seventeen B. bassiana isolates was investigated in the present study. High protease activity was observed during four to six days of culture incubation. Induction mechanism of subtillisin type Pr1 and trypsin type Pr2 activity were investigated utilizing different media. Minimal medium supplemented with casein (1%) showed high protease production and minimal medium supplemented with colloidal chitin (2%) was also able to induce Pr1 activity. The pH, ammonia and oxalic acid production in in vitro conditions was also investigated and the alteration in pH for protease production was not significant irrespective of the medium used. The protease activity gel was also studied and a common 66 kDa protease was observed in all the seven isolates studied.[...] Read More.
