Growth and Blood Parameters of Weaned Crossbred Beef Calves Fed Forage Kale (Brassica oleraceaspp.acephala)

Forty lightweight calves (206.4±3.2 kg) were randomly distributed to four treatments: (Control) low nutritive value pasture and hay plus 1 kg d−1of rolled barley; (Pasture) management intensive pasture; (Haylage) timothy haylage; and (Kale) 50% timothy haylage −50% kale pasture. Blood samples were analysed for thyroid hormones, liver enzymes, glucose, cholesterol, total proteins (TP), albumin, globulins, and urea-N. At the end of the trial, the Pasture group was the heaviest with323.6±4.2 kg BW and 1.54 kg ADG. Final BW and ADG were similar for the Kale and Haylage groups. Blood T3was higher for Kale than for the other groups. The T3/T4ratio was greater for Control at the end of the experiment. There were no treatment differences for T4, aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), glutamate dehydrogenase (GLDH), cholesterol, and glucose. Blood urea-N was lower for Kale and higher for Pasture; however albumin concentrations were greater for Pasture and similar for other treatments. Except for the Control group, calves had a lower concentration of circulating globulins at the end than at the beginning of the experiment. This study showed that Kale could be fed to backgrounding calves without detrimental effects on performance.

The aim of our experiment was to compare the effect of different levels of the addition ofSaccharomyces cerevisiae (S. c.)yeast culture on feed carrier to the current ration MK DOJ Levucell SC 20, Saccharomyces cerevisiae CNCM I-1077 (E 1711) 20.1010CFU on the blood parameters of high-pregnant breeding cows and their calves. The experiment included 42 breeding cows of the Czech Fleckvieh cattle breed and their calves. The breeding cows were divided into two age groups, each of 21 heads. The first group included heifers and the second group consisted of cows on the 2ndand higher lactation. Each age group had 7 control animals (Heifers/Cows – control), 7 animals receiving 50 g of yeast culture on the feed carrier per head and day (Heifers/Cows – 50 g), and 7 animals receiving 150 g of yeast culture on the feed carrier per head and day (Heifers/Cows – 150 g). Blood of the animals was sampled three times during the experiment – two times in the cows and one time in their calves. The first blood sample was taken from the breeding cows before the start of feeding the yeast culture ca. 23 days before the expected parturition (Cow −23). The second blood sample was taken from the breeding cows within 24 hours after birth (Cow +2) and the third blood sample was taken from the calves on the 3rd–4thday after birth (Calf +4). Parameters ascertained in the processed serum were: immunoglobulines G (IgG), crude protein (CP), gamma glutamyl-transferase (GGT), urea, glutamate-pyruvate-transaminase (GPT) and glutamate-oxaloacetate-transaminase (GOT). Results of our experiment, which lasted from 16.3 to 28.6 (105 days) showed IgG in the serum of cows on the 2ndand higher lactation in the control group (3.8 ± 1.48 mg/ml) was statistically significantly lower (P < 0.05) in the blood sample Cow +2 than in the serum of cows in the 2ndand higher lactation fed with the lower concentration ofSaccharomyces cerevisiaeat the same sampling (15.9 ± 11.41 mg/ml). This correlates also with the fact that the content of IgG antibodies in the serum of calves after the cows on the 2ndand higher lactation in the control group (3.9 ± 2.06 mg/ml) was statistically significantly (P < 0.05) lower than that of calves after the cows on the 2ndand higher lactation with the lower concentration ofSaccharomyces cerevisiae(14.6 ± 8.67 mg/ ml).As to the higher addition, no statistically significant difference of the effect on the IgG content was recorded (P < 0.05).

Introduction: The increased prevalence of overweight, obesity, and metabolic syndrome has revealed that liver enzymes have a potential role as determinants of metabolic conditions such as, hyperlipidemia, and Cardiovascular Disease (CVD). Aim: The study aimed to investigate the correlation between liver enzymes with anthropometric indices of obesity and lipid profile in different obese phenotypes at a tertiary care. Materials and Methods: The present observational study was conducted on a total of 180 obese participants of either gender in the age group 18-59 years from December 2018 to May 2019. These were further divided into two phenotypic groups viz., Metabolically Healthy Obese (MHO group; n=90) and Metabolically Unhealthy Obese (MUHO group; n=90) according to NCEP ATP III criteria.Traditional cardiovascular risk factors were evaluated in the study participants through anthropometric viz., Body Mass Index (BMI), Waist Circumference (WC), Hip Circumference (HC), waist–hip ratio (WHR), blood pressure and biochemical investigations i.e., serum glucose, lipid profile and liver enzymes. Data was analysed by using Microsoft excel software. Results: Among 180 obese participants, 76 were males and 104 females with mean age 40.42±10.84 years. In MUHO phenotype, Gamma Glutamyl Transferase (GGT) showed a strong positive correlation with BMI (r=0.413, p=0.00001), lipid parameters viz., LDL-C (r=0.3785, p=0.0001), TC (r=0.2953, p=0.0023), TG (r=0.2623, p=0.006) and negative correlation with HDL-C (-r=0.3167, p=0.001). No significant correlation was found in MHO phenotype between liver enzymes, BMI and lipid profile parameters. Conclusion: The results of this study indicated that GGT shows a strong positive correlation with traditional risk factors in MUHO participants. Thus, raised GGT may be considered as a risk marker of CVD in MUHO phenotype.

Diagnosed Diabetes

Introduction: Liver disease and diabetes often co-occur and have shared risk factors. We undertook this study to investigate which liver enzyme (alanine aminotransferase (ALT), aspartate aminotransferase (AST), or gamma-glutamyl transferase (GGT)) would be most strongly associated with incident diabetes in a large, community-based population. Hypothesis: We hypothesized that ALT, AST, and GGT would be independently associated with diabetes and that ALT would be most strongly associated with diabetes due to its liver specificity. Methods: We conducted a prospective analysis of 9,524 participants in the ARIC Study without diagnosed diabetes or a history of high alcohol consumption (>14 [women] and >21 [men] drinks/week). Enzymes were measured from stored plasma samples. We examined the association of sex-specific quartiles of liver enzymes with incident diagnosed diabetes using Cox proportional hazards models adjusted for demographic, lifestyle, and behavioral risk factors. Restricted cubic spline models were fit to model the continuous associations. Results: Median ALT, AST, and GGT were 13, 18, and 22 U/L, respectively. During a median follow-up of 11 years, there were 1,905 self-reported cases of diabetes. All three liver enzymes were significantly associated with diabetes, even after adjustment for all covariates (HRs (95% CIs): ALT, 1.63 (1.44, 1.85); AST, 1.23 (1.09, 1.40); GGT, 1.99 (1.71, 2.30) comparing Q4 versus Q1). The restricted cubic spline models show similar patterns (Figure). After simultaneously adjustment for the other liver enzymes, only ALT and GGT remained significantly associated with diabetes. In analyses further restricted to participants who reported never consuming alcohol only GGT remained significant. Conclusion: In this community-based population, GGT was more strongly associated with diabetes risk than ALT and AST. Although ALT and AST are considered to be more specific markers of liver disease, higher levels of GGT may be a more important risk factor for diabetes.

Background: Tacrolimus is a calcineurin inhibitor widely used for immunological disorders. However, there is a significant controversy regarding its effect on the liver. The present study was conducted to evaluate the anticancer effects of tacrolimus on an induced murine hepatocellular carcinoma (HCC) model and its possible hepatotoxicity at standard therapeutic doses. Methods: Fifty-four male mice were divided into five groups: a control healthy group, control HCC group, tacrolimus-treated group, doxorubicin (DOXO)-treated group, and combined tacrolimus- and DOXO-treated group. The activity of liver enzymes, including alkaline phosphatase, gamma-glutamyl transferase, lactate dehydrogenase, alanine transaminase, and aspartate transaminase, was determined. Serum vascular endothelial growth factor (VEGF) was measured using an enzyme-linked immunosorbent assay. A quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to measure the expression of proliferating cell nuclear antigen (PCNA), Bax, and p53 mRNA. Immunohistochemical staining for cyclin D1 and VEGF was performed. Results: Mice that received combined treatment with tacrolimus and DOXO exhibited the best improvement in all parameters when compared with the groups that received DOXO or tacrolimus alone (p < 0.001). Conclusion: The combination of DOXO and tacrolimus was more effective in the management of HCC compared with either agent alone. This improvement was detected by the reduction of liver enzymes and the improvement of the histopathological picture. The involved mechanisms included significant apoptosis induction demonstrated by upregulation of bax along with a reduction in angiogenesis demonstrated by downregulation of VEGF. This was accompanied by inhibition of cell cycle progression mediated by upregulated p53 and downregulated PCNA and cyclin D1.

Objective: The current study was designed to estimate the potential protective role of the aqueous extract of rosemary (AER) (Rosmarinus officinalis) against trichloroacetic acid (TCA)-created hepatotoxicity in male albino rats.Methods: Forty male albino rats were separated into four groups of ten: Group I served as control; Group II was given AER (200 mg/kg/day) by gavage; Group III received TCA at the dose 50 mg/kg/day, and Group V was treated with AER (200 mg/kg/day) and received TCA (50 mg/kg/day). The experiment was carried out for 2 months.Results: The toxicity of TCA for rats was revealed by an elevation in liver marker enzymes activities (gamma-glutamyl transferase [GGT], alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and conjugated bilirubin (CB) level, and a decrease in albumin and total protein (TP) levels. The TCA administration also caused a significant increase in the activities of catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and also malondialdehyde (MDA) level in liver tissues. These biochemical effects were accompanied by histological indicators of liver damage. Treatment with ARE recovered the liver damage instigated by TCA, as showed by perfection of liver enzyme markers (GGT, ALT, AST, ALP), CB, TP and albumin; as well as antioxidant parameters (CAT, SOD, GPx) and lipid peroxidation (MDA) and amelioration of histopathology changes in the liver tissues.Conclusion: It could be concluded that AER supplementation for 2 months in TCA-induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.

The Impact

It is common for food to be made more palatable through the use of the flavour enhancer monosodium glutamate, also known as vetsin powder. The purpose of the study described in this paper was to explore how vetsin-induced hepatic toxicity, DNA fragmentation, damage, and oxidative stress modifications could be mitigated with moringa leaf extract (MLE). To that end, 40 male rats were separated into four groups: normal control, positive control or MLE, vetsin, and vetsin combined with MLE. Results indicated that, compared to the control group, the levels of serum alanine aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), liver malondialdehyde (MDA), DNA damage, injury, PCNA, and P53 expressions were significantly enhanced by the administration of vetsin (P<0.05). However, the vetsin group had significantly reduced levels of albumin, globulin, total protein, liver glutathione (GSH), superoxide dismutase enzyme (SOD), catalase, and glutathione S-transferase (GST) enzyme activities (P<0.05) by comparison to control. Meanwhile, modifications in liver functions, oxidative stress, DNA damage, liver injury, and PCNA expression were alleviated when vetsin was administered alongside MLE. The authors conclude that vetsin may have many side effects and that MLE can ameliorate biochemical changes, oxidative stress, hepatic injury, PCNA, and P53 alterations induced by vetsin administration.

BackgroundCharacteristics of laboratory findings of COVID-19 patients are of great significance for diagnosis and treatment. Studies that have analysed the variations in hepatic profile in correlation with the inflammatory markers in SARS-CoV-2 are limited.MethodsWe retrospectively analysed liver function tests and inflammatory markers of 170 admitted patients with conﬁrmed COVID-19 in the tertiary care centre, Post Graduate Institute of Medical Education and Research (PGIMER), India, using Roche Cobas Autoanalyzer.ResultsNumber of patients with normal liver enzyme levels were 63 (41.5%), while with raised levels of any of the liver enzymes were 89 (58.5%), out of which 43 (48.31%) had liver injury which manifested as increased severity in terms of intensive care unit (ICU) requirement (p=0.0005). Significantly raised levels of liver enzymes and liver injury were observed with age (p<0.0001) and in males (p=0.004). Significantly decreased levels of albumin and total proteins and increased levels of total bilirubin (p<0.0001) were seen in patients with abnormal liver enzyme levels and liver injury as compared to patients with normal levels. Significant increase in the levels of alanine transaminase and gamma-glutamyl transferase was seen on the 7th day, CRP and ferritin (p<0.0001) peaks were observed on 2nd and 3rd day respectively. A significant positive correlation was found between the levels of these inflammatory markers and liver function parameters.ConclusionsMore than half of patients admitted to the hospital with SARS-CoV-2 infection had an abnormal liver function which was found to be associated with raised levels of inflammatory markers. Signiﬁcantly higher proportions of patients with abnormal liver function were elderly and males and were at higher risk of progressing to severe disease.

Glutamyl Transferase

Mercury (Hg) is a toxic heavy metal, and the reported effects of exposure on liver function continue to be inconsistent. The objective of our study was to identify correlations between high blood Hg levels and liver enzymes in a pan-India population including adults ≥19 years of age. This retrospective study analyzed the data from 95,398 individuals tested for blood Hg levels and liver enzymes in our national laboratory. Testing for blood Hg was done by inductively coupled plasma-mass spectrometry, while testing for liver enzymes—aspartate aminotransferase (AST/SGOT), alanine aminotransferase (ALT/SGPT), and gamma-glutamyl transferase—was done by automated photometry systems. Data from all the individuals inclusive of 52,497 males and 42,901 females were studied. The frequency of high blood Hg levels (>5 µg/L) was found to be 0.6%, and the difference between males and females was not found to be significant. Further correlation by linear regression analysis found no relationship between high blood Hg levels and liver enzymes among females. However, among males, there was a significant correlation between high blood Hg levels, and increased AST as well as ALT. Our report suggested that for males but not females, Hg exposure may be one of the differentials for elevated liver enzymes.

BACKGROUND: The choledocolithiasis has an incidence of 8-20% in patients with cholecystolithiasis. The preoperative diagnosis guides the interventional treatment on the bile duct AIM: To evaluate the sensitivity and specificity of the laboratory markers and imaging studies for choledocholithiasis preoperatively. METHODS: The study comprised 254 patients divided into two groups: the control group (207 patients), patients without choledocholithiasis intraoperatively and cases group (47 patients), that enrolled the patients with choledocholithiasis intra-operatively. Were evaluated the laboratory markers, image exams and intra-operative diagnostic aspects. RESULTS: The sample was homogeneous for age and gender. It was observed that 47% of the cases the patients did not show comorbidities. Hospitalization showes in cases group acute pancreatitis in12.8%, jaundice in 30%, fever in 30% and pain in the right hypochondrium in 95%. By comparing them, was observed that fever and jaundice were the signs and symptoms with statistical significance. Patients with choledocholithiasis had transaminases, alkaline phosphatase, gamma-glutamyl transferase and higher bilirubin with statistical significance (p<0.001). In regard to imaging studies, ultrasound was fairly accurate for cholelithiasis and choledocholithiasis (p<0.001). CONCLUSION: Changes in canalicular and transaminase enzymes are suggestive for preoperative choledocholithiasis; GGT showed better sensitivity and alkaline phosphatase greater specificity; ultrasonography and nuclear magnetic resonance cholangiopancreatography showed high specificity.

Abstract The purpose of the present study was to analyse the changes in concentrations of total proteins, albumin, globulins and albumin/globulin ratio in dogs with experimentally induced acute inflammation. The study was performed on 9 mongrel dogs (experimental group) and 6 mongrel dogs (control group) at the age of 2 years and body weight 12-15 kg. The acute inflammation was reproduced by inoculation of 2 ml turpentine oil in the lumbar region subcutaneously and in same quantity saline in control dogs. Blood samples were collected into heparinized tubes before inoculation (hour 0) then at hours 6, 24, 48, 72 and on days 7, 14, 21. The statistical analysis of the data was performed using one way analysis of variance (ANOVA). The level of albumin statistically decreased in the experimental dogs from at 72nd h to day 14 while the concentration of globulins increased from the 72nd h to day 21. On days 7 and 14 the albumin/globulin ratio slightly decreased. During the whole post inoculation period the values of total protein have not changed. The dates of the present study confirm that albumin, albumin/globulin ratio and globulins are sensitive factors in inflammatory conditions in dogs.
