The purpose of this study is to investigate the effect ofGinkgo bilobaleaves extract on experimental liver fibrosis induced by thioacetamide (TAA) in male albino mice. The experimental mice were divided into four groups. The mice of the first group were served as control. The experimental animals of the second group were given 150 mg/kg body weight of TAA by intraperitoneal injection, twice weekly, for 9 weeks. The mice of the third group were exposed to TAA and supplemented withG. bilobaleaves extract. The animals of the fourth group were supplemented withG. bilobaleaves extract. The levels of plasma alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, triglycerides, cholesterol, and low-density lipoprotein cholesterol were statistically increased while the levels of plasma total protein, albumin, glucose, and high-density lipoprotein cholesterol were significantly decreased. The levels of liver superoxide dismutase, glutathione, glycogen and total protein were notably declined, whereas the level of total lipid was increased in mice of the second group. Furthermore, microscopic examination of liver sections from mice treated with TAA showed an abnormal morphology characterized by nodular transformations in liver parenchyma which surrounded by fibrous septa. Administration ofG. bilobaleaves extract reduced extent and development of fibrous septa, liver cells change, and biochemical alterations in mice exposed to TAA. This study showed thatG. bilobaleaves extract has a potential activity against TAA-induced liver fibrosis and suggested that the chemical constituents ofG. bilobaare effective in modulation of oxidative stress induced by TAA.

Medication use during pregnancy is challenging due to the occurrence of maternal or fetal toxicities. Atazanavir/ritonavir (ATV/r) has hepatotoxic potential hence; use in pregnant patients living with human immunodeficiency virus may cause maternal hepatotoxicity. This study assessed the liver profile of ATV/r in pregnant albino rats. Thirty pregnant albino rats randomized into groups were orally treated daily with ATV/r (4.28/1.43 mg/kg-34.3/11.4 mg/kg) for 16 days. After treatment, the rats were weighed and sacrificed. Blood samples were collected and examined for serum biochemical parameters. Liver samples were weighed and assessed for biochemical and histological changes. Body and liver weights were normal (p>0.05) in ATV/r-treated pregnant rats when compared to control. Serum total cholesterol, triglyceride, low density lipoprotein cholesterol and blood glucose levels were significantly (p<0.01) elevated whereas high density lipoprotein cholesterol level was significantly (p<0.01) decreased in rats treated with ATV/r (34.3/11.4 mg/kg) when compared to control. Liver and serum aminotransferases, alkaline phosphatase, gamma-glutamyl transferase, lactate dehydrogenase, total bilirubin, and conjugated bilirubin levels were significantly increased in a dose-dependent fashion in rats treated with ATV/r; 8.57/2.86 mg/kg (p<0.05), 17.1/5.72 mg/kg (p<0.01) and 34.3/11.4 mg/kg (p<0.001) when compared to control. Liver superoxide dismutase, catalase, glutathione and glutathione peroxidase levels were significantly decreased whereas malondialdehyde levels were significantly increased in a dose-dependent fashion in rats treated with ATV/r; 8.57/2.86 mg/kg (p<0.05), 17.1/5.72 mg/kg (p<0.01) and 34.3/11.4 mg/kg (p<0.001) when compared to control. Necrotic hepatocytes were observed at higher doses of ATV/r. ATV/r may not be hepatotoxic in pregnant women living with HIV at the clinical dose.

IntroductionLonger duration of lactation is associated with lower cardiometabolic disease risk, but pathogenic pathways involved in the disease progression are unclear, especially among high-risk women. We aimed to examine the associations of lifetime lactation duration with cardiometabolic biomarkers among middle-aged women with a history of gestational diabetes (GDM).Research design and methodsWomen with a history of GDM participating in the Nurses’ Health Study II, a prospective cohort study, were identified and followed through biennial questionnaires beginning in 1991. Lactation history was asked in three follow-up questionnaires to calculate lifetime duration. In 2012–2014, fasting blood samples were collected through the Diabetes & Women’s Health Study to measure inflammatory (C-reactive protein (CRP), interleukin (IL) 6), liver enzyme (alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase), and lipid biomarkers (total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol).ResultsAt follow-up blood collection, women were at median age 58.2 (95% CI 51 to 65) years and 26.3 (95% CI 15.7 to 34.1) years since GDM index pregnancy. After multiple adjustment including prepregnancy body mass index (BMI), longer duration of lactation was significantly associated with lower CRP (least squares (LS) mean 1.90 mg/L (95% CI 1.47 to 2.45) for 0-month lactation, 1.98 mg/L (95% CI 1.68 to 2.32) for up to 12-month lactation, 1.67 mg/L (95% CI 1.42 to 1.97) for 12–24 month lactation, and 1.39 mg/L (95% CI 1.19 to 1.62) for >24-month lactation; p trend=0.003) and IL-6 (1.25 pg/L (95% CI 0.94 to 1.68), 1.19 pg/L (95% CI 0.99 to 1.42), 1.04 pg/L (95% CI 0.87 to 1.25), and 0.93 pg/L (95% CI 0.78 to 1.11); p trend=0.04). Longer duration of lactation was associated with lower risk for chronic inflammation using CRP 3 mg/L cut-off in middle-aged women (OR 0.81 (95% CI 0.69 to 0.940 per 1-year increase) with multiple adjustment.ConclusionsLonger lifetime duration of lactation was associated with favorable inflammatory biomarker concentrations in middle-aged women with a history of GDM. Chronic inflammatory pathways may be responsible for previously reported associations between lactation and long-term risk for cardiometabolic diseases.

The serum protein test includes measurement of the level of total protein(albumin, globulin). Fetuin-A is a blood protein made in liver. It can inhibit insulin receptor, enhance insulin sensitivity and make the individuals more likely to develop type 2 diabetes, then disorder in lipid profile (Total cholesterol(TC), low density lipoprotein cholesterol (LDL-c), high density lipoprotein cholesterol (HDL-c), Triglyceride(TG) and very low density lipoprotein cholesterol (VLDL-c) . To evaluate Fetuin-A, total protein, albumin, globulin, HbAlc and lipid profile in 200 adult and elderly Iraqi patients with type 2 Diabetes Mellitus were taken and compare them with 200 subjects as a healthy control. The laboratory analysis(for patients and control ) were performed to determine these parameters .The results show that FBG. HbA1c, Lipid profile for (patients and control) (except HDL-c) were increase with age with a significant difference (p0.05) between male and female. Serum total protein, globulin, Fetuin-A, increase with age while albumin decrease with age(in patients and control).

The study aimed to determine the biochemical reference ranges for lambs from birth to 1 year of age in the tropics. Data were obtained from experiments performed in several institutions and commercial farms using Santa Inês, Dorper, Lacaune, Morada Nova, Bergamacia and Suffolk lambs reared under different conditions (grazing, feedlot, semi-feedlot) from 2006 to 2017. Serum energy-, protein-, mineral-, and enzyme-related metabolites were evaluated. The metabolic energy profile included data from glucose, cholesterol, triglycerides, fructosamine, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and very-low-density lipoprotein cholesterol; the metabolic protein profile included total protein, uric acid, urea, albumin, and creatinine; the metabolic mineral profile included data on calcium, phosphorus, and magnesium; and the metabolic enzymatic profile included the enzymes aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, and creatine kinase. The reference ranges were estimated using confidence intervals with a 95% confidence level, and percentiles were estimated or bootstrapped nonparametrically when the data were not normally distributed. The serum biochemical reference ranges determined for lambs are strongly divergent from those established by one of the most cited books on the topic, especially considering the high serum urea and cholesterol concentrations and low levels of blood glucose observed. Therefore, the serum biochemical reference ranges for lambs from birth to 1 year of age in the tropics differ from international data, which consider adult sheep in temperate climate zones.

Background: The study sought to determine the correlation between the onset and severity of preeclampsia (PE) and maternal sociodemographic variables: age, parity and body mass index (BMI); medical history: systolic blood pressure (SBP), diastolic blood pressure (DBP), and proteinuria; fasting lipids: total cholesterol (TCHOL), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglycerides (TRIG); liver enzymes: aspartate transaminase (AST), alanine transaminase (ALT) and gamma-glutamyl transferase (GGT), and other variables: serum neutrophil gelatinase associated lipocalin (sNGAL), endothelin-1 (ET-1) and creatinine (CRT). Methods: This was a case–control study from January–June 2018. The study involved 270 pregnant women aged 18–37 years. Half of the study population (n=135) had PE and were categorized into either early-onset PE (EOPE) or late-onset PE (LOPE) and whether the PE was characterized by severe features (PS) or without severe features (PNS). The cases (PE) were matched by maternal and gestational age to 135 women with normotensive and uncomplicated pregnancies. A single venous blood sample was collected after an overnight fast and analysed using ELISA or routine biochemistry technique. Results: Maternal blood lipids (except HDL), liver enzymes (except GGT), CRT, sNGAL, ET-1, proteinuria, and BMI were positively correlated while HDL was negatively correlated with the onset and severity of PE (P<0.050). Conclusion: There are significant correlations between maternal variables and the onset and severity of PE. These findings are useful for the early detection and management of PE, especially in resource-limited settings.

Background: Piroxicam is one of the nonsteroidal anti-inflammatory drugs used as antipyretic, analgesic and anti-inflammatory drug often used for the relief of nonspecific fever condition and in arthritis. This study investigated the protective potential of tannin-rich extract of Chasmanthera dependens (TRECDS) against piroxicam-induced hepatotoxicity in male Wistar rats.Materials and Methods: Thirty two rats were divided into four groups. Group 1 received normal saline and served as the control group, group 2 were given 20 mg/kg piroxicam only, while groups 3 and 4 were given 20 mg/kg piroxicam with the addition of 200 and 400 mg/kg of tannin-rich extract of Chasmanthera dependens, respectively. All rats were treated orally once daily for ten days.Results: Administration of piroxicam caused liver atrophy demonstrated by significant rise in serum alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), glucose-6-phosphate dehydrogenase (G6PDH) levels of albumin (ALB), bilirubin (BIL), total cholesterol (TCHOL), triglyceride (TRIGS) and low-density lipoprotein (LDL). Piroxicam also decreased high-density lipoprotein (HDL) level, enzymatic and nonenzymatic antioxidant levels significantly (p>0.05) with attendant increase in oxidative stress indices in the liver of rats compared with control group. Histological assessment reveled severe damaged to the liver of rats. However, co-administration with TRECDS reversed these observations as evidenced in the histological results.Conclusion: The findings of this study showed that exposure of rats to piroxicam provoked damage to the liver via oxidative damage and TRECDS has the potential of ameliorating the damage.Keywords: hepatotoxicity, piroxicam, Chasmanthera dependens, oxidative stress

ABSTRACTObjective: Obesity, characterized by an increase in excessive fat accumulation, represents a social problem worldwide and has been recognizedas a major underlying factor in the pathogenesis of several diseases. Gamma-glutamyl transferase (GGT) is a cell-surface protein contributing tothe extracellular catabolism of glutathione. Elevated GGT is strongly associated with obesity and excess deposition of fat in the liver, termed nonalcoholicfatty liver disease, which is thought to cause hepatic insulin resistance and contribute to the development of systemic insulin resistanceand hyperinsulinemia. Therefore, we have investigated the serum GGT levels in obese individuals and the correlation of serum GGT with bodymass index (BMI) and waist circumference.Methods: The study was carried out in 100 obese patients and 100 non-obese individuals.Results: Patients with obesity showed a significant increase in GGT levels when compared to the control group. The mean levels of BMI, WC, totalcholesterol, triglycerides, low-density lipoprotein-cholesterol (LDL-c), very LDL-cholesterol, total protein, and aspartate aminotransferase werefound to be significantly elevated in the obese individuals compared to controls. The mean levels of high-density lipoprotein-cholesterol showed asignificant decrease in the obese participants.Conclusion: Elevated liver enzymes, although in normal ranges, especially at upper quartiles as observed in our study, may play a central role inearly diagnosis of fat overflow to the liver. The findings of our study suggest that serum GGT levels may be a simple and reliable marker of visceral fataccumulation.Keywords: Diabetes mellitus, Gamma-glutamyl transferase, Insulin resistance, Metabolic syndrome, Obesity.
