We investigated the change of tryptophan-niacin metabolism in rats with puromycin aminonucleoside PAN-induced nephrosis, the mechanisms responsible for their change of urinary excretion of nicotinamide and its metabolites, and the role of the kidney in tryptophan-niacin conversion. PAN-treated rats were intraperitoneally injected once with a 1.0% (w/v) solution of PAN at a dose of 100 mg/kg body weight. The collection of 24-hour urine was conducted 8 days after PAN injection. Daily urinary excretion of nicotinamide and its metabolites, liver and blood NAD, and key enzyme activities of tryptophan-niacin metabolism were determined. In PAN-treated rats, the sum of urinary excretion of nicotinamide and its metabolites was significantly lower compared with controls. The kidneyα-amino-β-carboxymuconate-ε-semialdehyde decarboxylase (ACMSD) activity in the PAN-treated group was significantly decreased by 50%, compared with the control group. Although kidney ACMSD activity was reduced, the conversion of tryptophan to niacin tended to be lower in the PAN-treated rats. A decrease in urinary excretion of niacin and the conversion of tryptophan to niacin in nephrotic rats may contribute to a low level of blood tryptophan. The role of kidney ACMSD activity may be minimal concerning tryptophan-niacin conversion under this experimental condition.

Reactive oxygen species caused by organophosphates may be involved in the toxicity of various pesticides. Therefore, in this study, we aimed to investigate the effects of acute exposure to organophosphate insecticide diazinon (DI) and possible ameliorating role of vitamins E and C, with the following parameters: lipid peroxidation (LPO) and the activity of the glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in rat erythrocytes. The experimental groups were arranged as control group, DI-treated group (DI) and DI + vitamin E + vitamin C—treated group (DI + Vit). DI + Vit groups were treated orally with a single dose of 335 mg/kg DI body weight. Vitamins E and C were injected at doses of 150 mg/kg body weight intramuscular (in) and 200 mg/kg body weight intraperitoneal (ip), respectively, 30 min after the treatment of DI in DI + Vit group. Blood samples were taken 24 h after the DI. The results showed that DI administration caused to increase in LPO and the activities of SOD and GSH-Px enzymes in erythrocytes. Also, the combination of vitamins E and C decreased LPO and the activities of GSH-Px and SOD compared with the DI group. In conclusion, although treating rats with single dose DI increases LPO and antioxidant enzyme activities in erythrocytes, vitamins C and E combination can reduce LPO caused by DI.

1. The nephrotic syndrome was induced in inbred female Wistar rats by the intravenous injection of puromycin aminonucleoside (PA) (5 mg/100 g body weight). 2. One group (n = 12) received superoxide dismutase (SOD) (15 mg/kg body weight), a second group (n = 12) received polyethylene glycol coupled catalase (PEG-catalase) (5000 i.u./kg body weight) and the third (n = 9) saline (150 mmol/l NaCl) via the intraperitoneal route, in addition to the PA. 3. SOD and PEG-catalase reduced the 24 h urine protein on days 8 and 15 compared with unmodified puromycin treated animals and this difference was significant on day 15 for SOD (P < 0.05) and for PEG-catalase (P < 0.01). Glomerular filtration rate, as measured by the creatinine clearance, was lower in the PEG-catalase group but did not differ significantly from the saline treated group. 4. These data suggest that superoxide anion and hydrogen peroxide, or their reaction products, are involved in the glomerular injury of puromycin nephropathy.

Adipogenic Gene

Excess body weight is a major risk factor for type 2 diabetes (T2D) and associated metabolic complications, and weight loss has been shown to improve glycemic control and decrease morbidity and mortality in T2D patients. Weight-loss strategies using dietary interventions produce a significant decrease in diabetes-related metabolic disturbance. We have previously reported that the supplementation of low molecular chitosan oligosaccharide (GO2KA1) significantly inhibited blood glucose levels in both animals and humans. However, the effect of GO2KA1 on obesity still remains unclear. The aim of the study was to evaluate the anti-obesity effect of GO2KA1 on lipid accumulation and adipogenic gene expression using 3T3-L1 adipocytes in vitro and plasma lipid profiles using a Sprague-Dawley (SD) rat model. Murine 3T3-L1 preadipocytes were stimulated to differentiate under the adipogenic stimulation in the presence and absence of varying concentrations of GO2KA1. Adipocyte differentiation was confirmed by Oil Red O staining of lipids and the expression of adipogenic gene expression. Compared to control group, the cells treated with GO2KA1 significantly decreased in intracellular lipid accumulation with concomitant decreases in the expression of key transcription factors, peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT/enhancer-binding protein alpha (CEBP/α). Consistently, the mRNA expression of downstream adipogenic target genes such as fatty acid binding protein 4 (FABP4), fatty acid synthase (FAS), were significantly lower in the GO2KA1-treated group than in the control group. In vivo, male SD rats were fed a high fat diet (HFD) for 6 weeks to induced obesity, followed by oral administration of GO2KA1 at 0.1 g/kg/body weight or vehicle control in HFD. We assessed body weight, food intake, plasma lipids, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) for liver function, and serum level of adiponectin, a marker for obesity-mediated metabolic syndrome. Compared to control group GO2KA1 significantly suppressed body weight gain (185.8 ± 8.8 g vs. 211.6 ± 20.1 g, p < 0.05) with no significant difference in food intake. The serum total cholesterol, triglyceride, and low-density lipoprotein (LDL) levels were significantly lower in the GO2KA1-treated group than in the control group, whereas the high-density lipoprotein (HDL) level was higher in the GO2KA1 group. The GO2KA1-treated group also showed a significant reduction in ALT and AST levels compared to the control. Moreover, serum adiponectin levels were significantly 1.5-folder higher than the control group. These in vivo and in vitro findings suggest that dietary supplementation of GO2KA1 may prevent diet-induced weight gain and the anti-obesity effect is mediated in part by inhibiting adipogenesis and increasing adiponectin level.

<p>ABSTRACT<br />Objective: The goal of the present study was to examine the viability of Morus alba (M. alba) ethanolic extract in repression of obesity-associated<br />hepatic steatosis and related metabolic disorder; dyslipidemia, hyperinsulinemia, and glycemic status.<br />Methods: Adult female albino rats were randomly assigned into four groups, eight rats each as follows: Group (1) control group received standard<br />rodent diet for 24 weeks. The other three groups administered high cholesterol diet for 12 weeks and served as obese group, M. alba-treated group,<br />and simvastatin-treated group.<br />Results: The current results showed an increment in thoracic circumference (TCX) and abdominal circumferences (AC) as well as body mass index<br />(BMI) in obese group. In addition, dyslipidemia, hyperinsulinemia, hyperglycemia, and insulin resistance have been elucidated in obese group.<br />Moreover, hepatic malondialdehyde (MDA), nitric oxide (NO), serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin<br />values were significantly increased in obese groups versus control group. On the other hand, administration of ethanolic extract of Morus alba or<br />simvastatin could significantly lessen BMI and in addition to improve dyslipidemia in obese group. Glucose, insulin levels, and insulin resistance value<br />in serum samples demonstrated a significant reduction in obese group upon treatment with M. alba ethanolic extract or simvastatin. Furthermore,<br />noticeable depletion in hepatic MDA, NO contents, serum ALT, AST activities, and serum bilirubin level was recorded as a result of treatment with<br />either ethanolic extract of M. alba or simvastatin. Histopathological examination of liver tissue showed ballooning degeneration in the hepatocytes<br />(hepatic steatosis) associated with inflammatory cells penetration in portal zone in obese group. Meanwhile, the treatment of obese groups with<br />ethanolic extract of M. alba or simvastatin was found to restore the structural organization of the liver.<br />Conclusion: The present findings provide a novel aspect for understanding of the role of M. alba against obesity-associated liver diseases and related<br />metabolic disorder. The mechanisms underlying these effects seem to depend on the hypolipidemic potential, anti-inflammatory property, and<br />antioxidant activity of its phytochemicals.<br />Keywords: Obesity, Morus alba, Dyslipidemia, Hyperinsulinemia, Hyperglycemia, Hepatic steatosis.</p>

In the porcine coronary artery, regenerated endothelium is dysfunctional as regards the responses to endothelium-dependent agonists. The current study aimed to determine the possible involvement of histamine in such dysfunction. Pigs were treated chronically with pyrilamine (H1 receptor inhibitor, 2 mg·kg−1·day−1) with part of their coronary endothelium and allowed to regenerate for 28 days after balloon denudation. The results showed a reduction in relaxation to bradykinin (Gq protein dependent) only in the pyrilamine-treated group (area under the curve, 269.7 ± 13.4 vs. 142.0 ± 31.0, native endothelium vs. regenerated endothelium) but not in the control group (253.0 ± 22.1 vs. 231.9 ± 29.5, native endothelium vs. regenerated endothelium). The differences in the relaxation to serotonin (Gi protein dependent) between native and regenerated endothelium were not affected by the pyrilamine treatment (control group, 106.3 ± 17.0 vs. 55.61 ± 12.7; and pyrilamine group, 106.0 ± 8.20 vs. 49.30 ± 6.31, native endothelium vs. regenerated endothelium). These findings indicate that during regeneration of the endothelium, the activation of H1 receptors by endogenous histamine may be required to maintain the endothelium-dependent Gq protein-mediated relaxation to bradykinin, suggesting a beneficial role of the monoamine in the process of endothelial regeneration.

The metabolic response to nutrient ingestion and the rate of digestion and absorption of nutrient molecules in bowel physiology plays an important role in the metabolic control of some human chronic non-infectious diseases. This experimentally-controlled designed nutritional study which lasted eight weeks aimed to determine the effects of proportional high-protein/low-carbohydrate (HP/LC) formulated diet on glycemic tolerance, glycemic control, body weight, organ weight and organ morphometry in healthy and diabetic adult male Wistar rats. Twenty-four male Wistar rats purchased from a disease-free stock were randomly categorized into four groups (n = 6, each) after two weeks acclimatization period in raised stainless steel cages with 6 mm2mesh floor and replaceable numbered blotters papers placed under each cage in a well-ventilated animal house. Animal groups include: Healthy control group (HC), Healthy treated group (HT), Diabetic control group (DC) and Diabetic treated group (DT. The animals were fed according to the experimental design with water ad libitumfor eight weeks. Diabetes was inducted with freshly prepared alloxan monohydrate solution (150 mg/kg bw, intraperitoneally). Body weights and fasting blood sugar concentrations were measured twice weekly, while oral glucose tolerance test was conducted on the last day of the eighth-week study and subsequently followed by organs extraction after anesthesia for weight and gross assessment. Proportional high-protein/low-carbohydrate formulated diet caused significant reduction in mean body weight of treated diabetic (DT: 22.6%; P= .001) and healthy (HT: 5.8%; P= .007) rats while the control animals on control diet recorded significant (P< .05) increase in body weight gain (DC: 12.4%; HC: 11.2%). Glycemic tolerance and control improved significantly in diabetic treated rats over that of the healthy treated rats. Gross morphometry of the extracted organs (kidneys, liver, heart, lungs, spleen and testes) revealed sustained normal morphological features without any visible lesion. In conclusion, consumption of proportional high-protein/low-carbohydrate formulated diet enhanced body weight reduction and sustained normal organ morphological features with good glycemic tolerance and control in experimental rats, suggesting its dietary potentiality, safety and suitability to ameliorate obesity-related diabetes.

ABSTRACT The metabolism of thyroxine (T4) was determined in untreated and in insulin-treated diabetic rats. The results were compared with those obtained in a control group. Male Wistar rats weighing approximately 200 g were made diabetic by the intraperitoneal administration of streptozotocin (6.5 mg/100 g body weight) and 17 of those with blood sugar levels above 500 mg/100 ml were studied. In addition, 11 insulin-treated diabetic and 18 control rats were investigated. All the animals were injected intravenously with a tracer dose of [125I]T4 (1 μCi and 0.015 μg). After this blood samples were obtained by cardiac puncture at 16, 24, 40 and 48 h. The 24-h urinary excretion of inorganic 125iodide was also determined. The parameters of T4 metabolism were obtained by the least squares method and by an extrapolation technique. In untreated diabetic rats the fractional T4 turnover was 4.4%h, the distribution space 36.7 ml/100 g body weight, metabolic clearance 1.57 ml/100 g/h and urinary clearance 0.33 ml/100 g/h. The 24-h urinary excretion of 125iodide was 21.3 % of the injected radioactivity. Of these values the distribution space (P < 0.001) and metabolic clearance (P < 0.05) were significantly increased above those in the control animals. In insulin-treated rats all parameters were within normal values. Among these groups the serum T4 concentration was measured in 6 control, 5 untreated diabetic and 6 insulin-treated animals. The untreated diabetic animals had a significantly decreased serum T4 level but this was balanced by an enlarged distribution space so that the final hormone degradation was normal. In addition, the T4 binding activity of serum was assessed by the in vitro red cells uptake of [125I] T4 and by determining the proportion of serum free T4. Both these indices indicated a decrease in serum binding activity in the diabetic animals. The data suggest that the fall in serum T4 levels observed in the untreated diabetic rats was the result of decreased plasma binding of T4 and an increase in distribution space precipitated by lack of insulin.

ABSTRACT We investigated the protective role of ceftriaxone plus sulbactam with VRP1034 (Elores) on hematological, lipid peroxidation, antioxidant enzymatic activities and Cd levels in the blood and tissues of cadmium exposed rats. Twenty-four male rats were divided into three groups of eight rats each. The control group received distilled water whereas group II received CdCl2 (1.5 mg/4 ml/body weight) through gastric gavage for 21 days. Group III received CdCl2 and was treated with ceftriaxone plus sulbactam with VRP1034 for 21 days. The hematological, biochemical, lipid per-oxidation levels and enzymatic parameters were measured in plasma and tissues (brain, liver and kidney) of all groups. The Cd, Zn and Fe levels were measured in blood and tissues of all groups. Our findings showed significantly decreased cadmium (p<0.001), malonaldialdehyde (p<0.001) and myloperoxidase (MPO) levels along with significantly increased hemoglobin (p<0.01), RBC (p<0.05), hematocrit (p<0.05) levels and all antioxidant enzymatic activities (SOD, CAT, GR, GPx) in plasma and tissues of ceftriaxone plus sulbactam with VRP1034 treated group as compared to cadmium exposed group. Delta aminolevulinate dehydratase (δ-ALAD) activity was significantly (p<0.001) increased in the blood of ceftriaxone plus sulbactam with VRP1034 treated group as compared with cadmium exposed group. The levels of hepatic and renal parameters were significantly (p<0.001) decreased in ceftriaxone plus sulbactam with VRP1034 treated group as compared to cadmium exposed group. These findings indicate that ceftriaxone plus sulbactam with VRP1034 acts as a potent free radical scavenger and exhibits metal chelating properties that reduce free radical mediated tissue injury and prevent dysfunction of hepatic and renal organs during metal intoxication.

In vertebrates, the primary cilium is a nearly ubiquitous organelle present in somatic cells, but little is known about its function in the male gonad. We investigated the role of primary cilia in testis cells using in vitro formation of seminiferous tubules and in vitro culture of testicular somatic cells by inhibiting the primary cilium with CiliobrevinD, a cell-permeable, reversible chemical modulator that inhibits the major component of the organelle: ATPase motor cytoplasmic dynein. We analysed in vitro cultures for the presence of primary cilia and the activation of hedgehog signalling through translocation of Gli2 to the nuclei; in vitro tubule formation was evaluated by length and width of tubules formed. Methods: testicular cells were harvested from neonatal pigs by 2-step enzymatic digestion. Cells (50 × 106 mL–1) were plated on 100 mm Petri dishes in 15 mL of DMEM + 5% FBS + 50 U of penicillin and incubated at 37°C in 5% CO2 in air overnight, cells remaining in suspension and those slightly attached were removed and the somatic cells attached were trypsinized to obtain a single cell suspension, and then submitted to two different protocols: in vitro culture (A) or in vitro tubule formation (B), n = 5 replicates each. For A, somatic cells were replated on coverslips in 24-well plates and cultured in serum free media for 48 h, then for the treated group, 10 mM of CiliobrevinD was added for 24 h, attached cells from control and treated groups were fixed in 4% PFA and characterised by immunocytochemistry for ARL13B, Vimentin, and Gli2. For B: 1 × 106 cells were added to 24-well plates coated with 1 : 1 diluted Matrigel, the control group was kept in serum free media and to the treated group was added 20 mM CiliobrevinD at Day 0. Results: A) primary cilia were present in 89.3 ± 2.3% of cells cultured in serum-free media for the control group and Gli2 was located in the nuclei of 90.2 ± 1.2% of cells; in the CiliobrevinD-treated group the percentage of primary cilia decreased (P < 0.05) to 3.1 ± 2.5% and nuclear Gli2 to 3.9 ± 0.7; B) tubules formed in the control group were significantly longer and wider than the ones formed when CiliobrevinD was added (9.91 ± 0.35 v. 5.540 ± 1.08 mm and 339.8 ± 55.78 v. 127.2 ± 11.9 µm, respectively, P < 0.05 by Student's t-test). In conclusion, the inhibition of ATPase motor cytoplasmic dynein perturbs formation of primary cilia in testicular somatic cells, blocks Hedgehog signalling, and impairs in vitro tubule formation. Therefore, primary cilia on testicular somatic cells appear to be essential for testicular morphogenesis.Research was supported by 5 R01 OD016575-13.
