The immunosenescence and lipotoxicity in thyrotoxicosis mice

COVID-19 is a worldwide outbreak now, and it is found to be age-related. Immunosenescence may be a predisposing and severe factor for COVID-19. Besides, many infectious diseases in clinic are age-related, and elderly patients have longer hospitalization and worse prognosis. Therefore, finding suitable aging models is of great significance for fighting aging related diseases and promoting the prognosis of elderly patients. In this study, the relationship between thyrotoxicosis and aging was investigated by routine detection and serum metabonomics in mice. The results of routine blood test and flow cytometry showed significant decrease in neutrophils, lymphocytes, CD4+/CD8+ and CD4+IFN-γ + lymphocytes in thyrotoxicosis mice. Biochemical examination combined with serum metabolomics analysis showed that serious disorder of lipid metabolism may be one of the causes of immunosenescence, including lower cholesterol levels, lower levels of VD and bile acids, high level of glucocorticoids, triglycerides, free fatty acids, Sphingolipids and decrease of Docosanoids, especially DPA. This study proves that thyrotoxicosis mice are an accelerated aging model. In present study, the main performance is immunosenescence, which may be due to lipotoxicity, suggesting that the immunosenescence state can be adjusted by improving lipotoxicity, whether anti thyroxine or not. However, there are other manifestations of thyroid toxicity mouse model simulating aging, such as organ aging, which need to continue to be studied by means of system biology to provide more comprehensive evidence.

Bacterial Shrimp Disease in Iraqi Marine Waters

A sample of 116 shrimps Metapenaeus affinis (H. Milne-Edwards, 1837) were collected from local fish markets in Basrah Province, Southern Iraq. Height, weight, and pathological signs of the shrimps were recorded. Both morphological and biochemical examination by VITEK identification system were undertaken. Pathological infections were seen on the cuticle of abdominal segments in addition to a severe infection in uropod (tail segment), rostrum and pleopods (walking legs). Results of biochemical identification showed the presence of Aeromonas sobria and A. salmonicida from the infected organs and this study is considered as the first record of this bacterial infection in shrimps in Iraq.

A STUDY ON ADENOSINE DEAMINASE AND C-REACTIVE PROTEIN IN CEREBROSPINAL FLUID OF MENINGITIS PATIENTS OF DIFFERENT TYPES.

Introduction: The three commonest types of Meningitis are Bacterial, Viral and Tubercular; they differ in their pathophysiology and management. That is why early differentiation between them is important. Bacterial meningitis have heavy fatality rates whereas Tubercular meningitis inicts severe neurological sequalae. Aims & Objectives: To determine whether ADA and CRP can be used successfully to predict the type of Meningitis affection Methodology: This is a Hospital based cross-sectional observation study which was undertaken in Biochemistry dept. Medical College, Kolkata. Eighty cases of meningitis were taken. ADA and CRP was measured along with Protein, Sugar and Differential staining cell counting. The cases were divided into three groups (Bacterial, Viral, and Tubercular) on the basis of microscopic and Biochemical Examination. Results & Analysis: ANNOVA test was done along with Bon Ferronis Test which revealed that there was signicant difference in mean of ADA & CRP in the three different groups.ROC curve for CRP between Reactive and Non-reactive meningitis revealed that if CRP values are more than 11.0, 95% of the cases were reactive whereas ROC curve for ADA between Tubercular and Non Tubercular forms showed when the concentration was more then 9.0, 95% of the cases were of Tubercular origin. Conclusion: When taken together ADA and CRP successfully predict the type of Meningitis. It is also helpful in diagnosing those cases when the Cell count and type was equivocal.

Evaluation of a Clinically Relevant Drug–Drug Interaction Between Rosuvastatin and Clopidogrel and the Risk of Hepatotoxicity

Purpose: The combination therapy of rosuvastatin (RSV) and the platelet inhibitor clopidogrel (CP) is widely accepted in the management of cardiovascular diseases. The objective of the present study was to identify the mechanism of RSV–CP DDI and evaluate the risk of hepatotoxicity associated with the concomitant use of CP.Methods: We first studied the effect of CP and its major circulating metabolite, carboxylic acid metabolite (CPC), on RSV transport by overexpressing cells and membrane vesicles. Second, we investigated whether a rat model could replicate this DDI and then be used to conduct mechanistic studies and assess the risk of hepatotoxicity. Then, cytotoxicity assay in hepatocytes, biochemical examination, and histopathology were performed to measure the magnitude of liver injury in the presence and absence of DDI.Results: CP inhibited OATP1B1-mediated transport of RSV with an IC50 value of 27.39 μM. CP and CPC inhibited BCRP-mediated RSV transport with IC50 values of <0.001 and 5.96 μM, respectively. The CP cocktail (0.001 μM CP plus 2 μM CPC) significantly inhibited BCRP-mediated transport of RSV by 26.28%. Multiple p.o. doses of CP significantly increased intravenous RSV plasma AUC0-infinity by 76.29% and decreased intravenous RSV CL by 42.62%. Similarly, multiple p.o. doses of CP significantly increased p.o. RSV plasma AUC0-infinity by 87.48% and decreased p.o. RSV CL by 43.27%. CP had no effect on cell viability, while RSV exhibited dose-dependent cytotoxicity after 96 h incubation. Co-incubation of 100 μM CP and RSV for 96 h significantly increased intracellular concentrations and cell-to-medium concentration ratios of RSV and reduced hepatocyte viability. Histological evaluation of liver specimens showed patterns of drug-induced liver injury. Cholestasis was found in rats in the presence of DDI.Conclusion: CP is not a clinically relevant inhibitor for OATP1B1 and OATP1B3. The primary mechanism of RSV–CP DDI can be attributed to the inhibition of intestinal BCRP by CP combined with the inhibition of hepatic BCRP by CPC. The latter is likely to be more clinically relevant and be a contributing factor for increased hepatotoxicity in the presence of DDI.

The toxicity of fumonisin B1on some biochemical and immunological parameters and its detoxification by red cabbage and garlic

The protective effects of red cabbage and garlic extracts against liver, kidney and thyroid gland damage induced by fumonisin B1 (FB1) in male mice were studied. Sixty mice divided in to six groups. Group one are the healthy mice, Group two are mice that received a daily oral dose of only FB-1 (100 µg/kg.b.w) for 1 month, Group three: are mice that received red cabbage extract (500 mg/kg.bw) plus FB1, Group four: are mice that received red cabbage extracts, Group five: are mice that received garlic extract (500mg/kg.bw) plus FB1, group 6:are mice that received only garlic extract. After finishing the experiments, samples of blood were used for biochemical examination. The results indicated that group (2) mice treated with fumonisin B1 had significantly increased levels of immunoglobulins (IgG and IgM), kidney function parameters (urea and creatinine), proteins (albumin and total protein (TP)), and thyroid hormones (T3 and T4), along with significantly decreased level of TSH (p < 0.05). In the LD50 experiment, we are choose concentration (100 µg/kg.b.w) gavage to the mice. Oral administration red cabbage garlic extracts produced significantl reduction the levels serum IgG, IgM, T3, T4, urea, creatinine, TP and albumin and with a significant increase in TSH.

Metabolic Syndrome as a Factor Affecting on Intima-Media Thickness in Patients with Rheumatoid Arthritis

AIM: The aim of the study was to assess the association of the thickness of the intima-media complex with metabolic syndrome (MetS) and the degree of disease activity in patients with rheumatoid arthritis (RA). MATERIALS AND METHODS: The study included 101 patients with RA. All patients underwent a biochemical examination, the presence of MetS was determined, and the carotid thickness of the intima-media was determined. Statistical processing was performed using SPSS for Windows, version 18.0. RESULTS: Among 101 patients with RA, 41 (40.5%) had MetS. The frequency of detecting an increased value of the intima-media complex thickness was significantly higher in the group with MetS (n = 31 [75.6%]) than in the group without MetS (n = 21 [35.0%] p ≤ 0.0001). In the group of patients with MetS, the median carotid intima-media thickness (CIMT) was 1.2 mm, while this indicator in the group without MetS was 0.78 mm (U = 727, p = 0.001). In the regression model, MetS (B = 1.05; p = 0.027) and DAS28-ESR (B = 0.506; p = 0.021) were influenced by CIMT. CONCLUSIONS: The results of our study show the effect of MetS and RA activity on the increase of intima-media thickness.

Haematological findings in 158 cows with acute toxic mastitis with a focus on the leukogram

Background In cows with acute toxic mastitis (ATM), the leukogram aids in the assessment of the severity of disease. The goal of our study was to compare the leukogram of 158 cows with ATM (cases) and 168 clinically healthy cows (controls). We hypothesised that the leukograms of surviving and non-surviving cows differ and that there are variables of the leukogram with sufficient prognostic potential to be used in the decision to treat or not to treat a cow with ATM. The cows were examined clinically and underwent haematological and biochemical examination of blood and bacteriological culture of milk samples. Results All cows with ATM had a poor appetite or anorexia, and 34 cows (21.5%) were recumbent. A single quarter was affected in 119 cows (75.3%), two quarters in 37 cows (23.4%) and three quarters in two cows (1.3%). Bacteriological culture showed Gram-negative pathogens in 100 cows (63.3%), Gram-positive in 15 (9.5%) and yeast in 4 (2.5%). The median total leukocyte count of cases was 4300 cells/µL (interquartile range = 2300–8200/µL), which was significantly lower than 8000 cells/µL (6525–9300/µL) in controls. Except for band neutrophils and metamyelocytes, the counts of all components of the leukogram were lower in cases compared with controls. Significantly more cows with ATM had leukopenia (60.1 vs. 4.1%) or leukocytosis (10.1 vs. 3.0%) than controls. Diseased cows had significantly lower segmented neutrophil counts than controls (860 vs. 2598 cells/µL), and 69.5 and 17.3%, respectively, had counts below the reference interval. Cases had increased band (77.3%) and metamyelocyte (25.0%) counts compared with controls (0.6 and 0%, respectively). In diseased cows, eosinopenia occurred in 66.4% (controls, 1.8%), monocytopenia in 40.6% (4.2%) and lymphopenia in 60.2% (1.8%). Twenty-one diseased cows (16.4%) had a regenerative and 57 (44.5%) had a degenerative left shift. The median neutrophil-to-lymphocyte ratio was 0.97 in diseased cows and 0.63 in controls. Toxic changes in neutrophils including cytoplasmic basophilia and vacuolisation were seen in 101 (91.8%) of 110 blood smears of diseased cows. The leukogram of the surviving and non-surviving cows did not differ significantly, and the hypothesis was rejected. Conclusions ATM results in severe changes in the leukogram particularly leukopenia, lymphopenia, and degenerative left shift. The hypothesis that the leukograms of surviving and non-surviving cows differ was rejected. The leukogram has not sufficient prognostic potential to be used in the decision to treat or not to treat a cow with ATM.
