Seronegative Polyarticular Juvenile Idiopathic Arthritis: A Case Report.

Juvenile idiopathic arthritis (JIA) is a chronic rheumatologic childhood disorder of unknown etiology usually presenting with peripheral arthritis. Usually involving the small joints symmetrically, polyarticular JIA is characterized by involvement of 5 or more peripheral joints and is further categorized depending on RA Factor positivity. We aim to report a case of seronegative polyarticular JIA to increase awareness regarding this disease. A 15-year-old boy presented with 3-month history of bilateral symmetrical joint pains, swelling and morning stiffness lasting 3-4 hours. For his ankle and knee pain, he had consulted a local doctor who suspected Rheumatic Fever and started penicillin and analgesics resulting in minimal improvement. He was a student but was unable to attend school in last 2 months due to this illness and had become bed-bound for last 2 weeks. On examination, there was swelling and tenderness of ankles, knees, elbows, wrists, metacarpophalangeal and proximal interphalangeal joints bilaterally. On investigation, ESR, CRP and serum ferritin were raised with normal complete blood count, urinalysis, liver and renal function tests, ASO test, blood and urine cultures, TSH, serum CPK and serum aldolase. Echocardiography did not reveal any abnormalities. His ANA, RA factor and Anti-CCP antibodies were negative. He was diagnosed with Seronegative Polyarticular Juvenile Idiopathic Arthritis and started on oral prednisolone and methotrexate. Currently the patient is asymptomatic on methotrexate 20mg/week. Our patient with symmetrical polyarthritis had negative ANA, RA Factor and Anti-CCP antibodies leading to a diagnosis of seronegative polyarticular JIA. Early screening and prompt management of JIA is required to improve prognosis and reduce risk of disability. The differential diagnosis of childhood joint pains is wide and variable including diseases of autoimmune, cardiac and haematological systems. For diagnosis of JIA, arthritis persisting for more than 6 weeks with onset of symptoms prior to 16 years of age is required with exclusion of secondary causes of joint inflammation. Keywords: Juvenile Idiopathic Arthritis, ANA, RA Factor, Anti-CCP antibodies, Methotrexate.

Typical and Atypical Manifestation of Scrub Typhus in Children

Introduction: Scrub typhus is grossly under-diagnosed or lately diagnosed in India because of its non-specific clinical presentation, a limited awareness about the disease, a low index of suspicion among clinicians, and a lack of diagnostic facilities. Absence of typical features may create diagnostic dilema among physicians thereby delaying the diagnosis which may lead to complications & high mortality. Material and method: A hospital based Cross sectional study which was conducted in the Department of Paediatrics, PRM Medical College, Baripada, Odisha from July 2021 to December 2021. Children from 1 month to 14 years of age presenting with fever in whom rickettsia infection is suspected included. All children who are found to be Elisa or IgM positive for scrub typhus even if admitted for other disease included. All fever cases with rash /oedema/ pallor/icterus/lymphadenopathy/hepatosplenomegaly and or any other systemic features with or without eschar was included. Results: The laboratory parameters of the cases are shown in Table 4. The total leukocyte count was elevated in 30.6% of the cases. An elevated serum creatinine level or a change in the serum creatinine level greater than 0.3 mg/dl, which is a diagnostic of AKI, was observed in 20% of cases. Hyponatremia was found in 6.9% of the cases. The serum CPK level (total and MB fraction) was elevated in 8.9% of cases. Conclusion: Pediatric scrub typhus is a common infection and should be suspected in cases with fever for more than 5 days and non-specific signs and symptoms. Early detection and timely management lead to a higher recovery rate. Hypotension, hypoxia, azotemia, altered sensorium, and bleeding manifestations on admission were associated with unfavorable outcomes.

Clinical and biochemical features of hypokalemic paralysis: a study from rural Eastern India

BackgroundHypokalemic paralysis is characterized by episodic attacks of flaccid muscle weakness of variable duration and severity associated with hypokalemia. Overall, there is a scarcity of data regarding hypokalemic paralysis from Indian subcontinent particularly from rural areas.MethodsA total of 50 consecutive patients of hypokalemic paralysis who were admitted in our hospital were recruited in this study.ResultsFifty patients of hypokalemic paralysis were admitted to our department over a period of 4 years. Forty-two (84%) patients presented with classic acute onset quadriparesis, while eight patients had atypical presentation. Five patients had paraparesis, two had hemiparesis and one patient presented with isolated neck muscle weakness without any limb weakness. Thirty-two patients had primary hypokalemic periodic paralysis (HoPP) and 18 had secondary hypokalemic paralysis. There was no significant difference in severity of weakness (p = 0.53), number of episodes of weakness (p = 0.66) and serum CPK levels (p = 0.36) between primary and secondary hypokalemic paralysis. Secondary cases required significantly prolonged time for recovery as well as higher potassium supplements as compared to the primary HoPP. The severity of weakness of proximal muscles measured in MRC grading showed a significant correlation with serum potassium levels (p = 0.010), but did not show any correlation with CPK Levels (p = 0.86).ConclusionHypokalemic paralysis is an important cause of acute flaccid paralysis in the Emergency Room that often improves dramatically with potassium supplements. While secondary cases often require treatment of underlying etiology, primary hypokalemic paralysis often requires chronic treatment with acetazolamide and/or potassium-sparing diuretics.

Comparison of Clinical Outcomes and Muscle Invasiveness between Unilateral Biportal Endoscopic Discectomy and Percutaneous Endoscopic Interlaminar Discectomy for Lumbar Disc Herniation at L5/S1 Level

Both unilateral biportal endoscopic discectomy (UBED) and percutaneous endoscopic interlaminar discectomy (PEID) could achieve favorable outcomes for lumbar disc herniation (LDH). There are limited studies comparing the two different methods of endoscopic discectomy. The objective was to comprehensively compare the clinical outcome and muscle invasiveness of UBED and PEID for the treatment of LDH at L5/S1 level with at least 1-year follow-up. The retrospective cohort study enrolled 106 LDH patients of L5/S1 level from January 2018 to December 2020. There were 51 patients who underwent UBED (22 males and 29 females, 43.8 ± 14.2 years old) and 55 patients underwent PEID (28 males and 27 females, 42.3 ± 13.8 years old). Clinical outcomes and surgical invasiveness were compared between the two groups for at least 1 year follow-up. Clinical outcomes included visual analogue scale (VAS) scores, Oswestry Disability Index (ODI), complications, recurrence of LDH, intraoperative anesthesia time, operative time, number of intraoperative fluoroscopies, and postoperative length of stay. Surgical invasiveness was evaluated with serum CPK level and change rate of lean multifidus cross-sectional area (LMCSA). Independent-sample t test and paired sample t test were used to compare continuous data. Chi-square test and Fisher's precision probability tests were used to analyze the categorical data. Both groups achieved favorable clinical outcomes at the last follow-up, including VAS and ODI (all Ps <0.05). The intraoperative anesthesia time for UBED was longer, but with no difference of operative time. As for intraoperative fluoroscopy times (2.5 vs 2.4), postoperative length of stay (2.1 vs 2.0 days), postoperative complications (5.9% vs 3.6%), there were also no significant difference. The serum CPK level and change rate of LMCSA for UBED was higher than PEID at postoperative 1st day. At the last follow-up, there was no significant difference in the change rate of LMCSA between the two groups (P=0.096). Both UBED and PEID could achieve favorable clinical outcomes for the treatment of L5/S1 LDH. Despite UBED is more invasive, the radiological manifestation of paraspinal muscle invasiveness was equal at last follow-up with at least 1 year. UBED is a safe and innovative alternative choice for treatment of LDH at L5/S1 level.

Assessment of Serum cholinesterase and Serum Creatinine Phosphokinase Levels in Organophosphorus Poisoning Patients at a Tertiary Care Centre of Northern India

Introduction: Poisoning with Organophosphorus compounds is an important global health problem, possibly the most common acute poisoning in developing countries. This study was done to correlate the severity of acute organophosphorus poisoning with serum cholinesterase and serum creatine phosphokinase level.Materials and Methods: A Prospective observational clinical study was done on 42 patients suspected of Organophosphorus poisoning of age &gt;15 years admitted to the emergency unit at a tertiary healthcare center in northern India. Serum cholinesterase levels and serum Creatinine phosphokinase levels were estimated at the time of admission in all patients and the severity of Organophosphorus poisoning was assessed according to Peradeniya Organophosphorous Poisoning (POP) Scale.Results: In this study, among 42 patients of acute organophosphorus poisoning 32(76.2%)were males and 10(23.8%) were females. Our study authors observed a significant correlation between the severity of poisoning categorized by the POP scale and the serum cholinesterase and Serum CPK level at the time of the patients’ initial presentation. Also found that there was a significant correlation between serum cholinesterase and serum CPK with the outcome of the patients.Conclusion: In our study severity as well as outcomes of OP poisoning was directly correlated with serum cholinesterase level and serum Creatinine phosphokinase.

Chemotherapy induced juvenile dermatomyositis: a novel presentation- a case report

BackgroundIdiopathic connective tissue disease juvenile dermatomyositis (JDM) is characterised by inflammatory myositis and distinctive skin abnormalities. Only a few cases of Dermatomyositis (DM) owing to chemotherapy used to treat cancer have been reported, despite the fact that the link between DM and cancer in adults is widely known. We describe the case of a female, age 14, who experienced DM as a side effect of chemotherapy following enucleation for retinoblastoma. We also discussed our patient's likely pathophysiology of JDM after treatment.Case presentationA 14-year-old female came to our facility complaining of trouble walking and bluish-black discoloration on her neck, elbows, forehead, and knees that had been present for eight months. The patient had undergone enucleation of the left eye due to retinoblastoma, followed by 40 cycles of radiation therapy and 13 cycles of chemotherapy with Cyclophosphamide, Etoposide, Carboplatin, Vincristine, and Dactinomycin. Her serum LDH and CPK levels were high, and she tested positive for ANA. The muscle biopsy was consistent with the changes of DM. When electromyography was performed, it revealed tiny, fibrillating, polyphasic motor unit potentials and sharp, positive waves that were suggestive with DM. A diagnosis of JDM was made after taking into account the symptoms, biochemical data, muscle biopsy, and electromyography results. The patient's symptoms started to get better once methotrexate and oral corticosteroids were started.ConclusionThis case report emphasises the value of ongoing observation after cancer chemotherapy because specific cutaneous and muscle symptoms may lead paediatricians to consider the possibility of chemotherapy-induced JDM, which is uncommon in young patients.

Protective Effects of Sauropus Androgynus Leaf Extract against Isoproterenol Induced Cardiotoxicity.

The identification of cardioprotective effects of the ethanolic extract of Sauropus androgynus (EESA) leaves was performed using in vitro and in vivo models. The cell culture studies were performed using cardio myoblast cells (H9C2) and in vivo cardioprotective effects of EESA was assessed in albino wistar rats employing isoproterenol (ISO) as cardiotoxic agent. The animals were divided into six treatment groups and myocardial infraction was induced at 14th day followed by the treatment with therapeutic doses of EESA (100, 200 and 400mg/kg) for next two days. Various biochemical and histopathological parameters were evaluated in animals kept under control and treatment groups. The in vitro cell line studies revealed a positive impact on H9C2 cells. The ethanolic extract of Sauropus androgynus depicted low toxicity on cardiomyoblast cells and significant proliferation was observed after treatment. The results from animal studies have shown 1.7 times reduction in serum LDH (151.9 ± 1.302) and CPK (237.6 ± 5.781) levels with EESA treated groups compared to toxic control. EESA also significantly increased the antioxidant enzyme levels, which are responsible for cardioprotective effects in animals. This research study reveals that EESA possess antioxidant activity and also provides a protective role against myocardial infarction induced by ISO. We conclude that EESA could be a potential candidate to prevent and treat cardiotoxic consequences of high catecholamine levels.

The Effect of Vitamin B17 on Cardiomyopathy against Ehrlich Tumor Development in Female Mice

The transplantable tumor model of Ehrlich ascites tumor (EAC), which is a cancer simulation, is frequently used to study the antineoplastic effects of amygdalin (VB17). This study aims to find out how cardiac toxicity and oxidative stress triggered by EAC could be countered with VB17 in female mice. Twenty-five female mice were included and divided into 5 groups namely, the control group (Gp1), EAC (Gp2), VB17 control group (Gp3), EAC+VB17 (Gp4), EAC+VB17+SOR IP (Gp5). All groups underwent cardiac marker assessment in addition to oxidative stress marker MDA determination and the evaluation of the anti-oxidative stress marker of SOD. By comparison with the naive control group, the EAC positive control group had a significantly higher level of Troponin, serum lactate dehydrogenase (LDH), CK-MB, CPK, and MDA content. On the other hand, the EAC group had significantly lower levels of cardiac SOD than the control group. Furthermore, better improvement in cardiac toxicity and oxidative stress was displayed by the cotreated (VB17+SOR) group 5 than by the (EAC + VB17) group 4. This led to the conclusion that VB17 conferred cardiac protective and antioxidant effects against EAC. This finding necessitates further research into the benefits of VB17 as adjuvant agents in the prevention and treatment of cardiac toxicity.

Studies of High Molybdenum-Induced Copper Deprivation in P. przewalskii on the Qinghai Lake Pasture in China

The Przewalski’s Gazelles (P. przewalskii) are affected by disorders that are characterized by deprived appetites, pica, emaciation and dyskinesia. The purpose of this study was to investigate the possibility of high molybdenum (Mo) in forage leading to copper (Cu) deprivation. The mineral contents in forage, soil, and samples of hair and blood from affected ranges were compared to healthy pasture. Blood parameters were also determined. Our results showed that the mean content of Mo in forage and soil in studied pasture was 5.17 and 4.17 μg/g, respectively. The Cu to Mo ratio in forage from affected and healthy areas was 1.26 and 5.89 μg/g, respectively. The Cu concentrations in hair and blood from gazelles in affected pasture were extremely lower (p &lt; 0.01) than those in unaffected animals. The Mo contents in hair were higher (p &lt; 0.01) than those in unaffected gazelles. The levels of Hb, RBC, PCV, MCV, and MCH in unaffected gazelles were significantly lower (p &lt; 0.01) than those in unaffected gazelles. The levels of TP, ALB and GLB in blood were significantly lower (p &lt; 0.01) than those in unaffected gazelles, while the levels of AST, LDH, CPK and ALP in serum were significantly higher (p &lt; 0.01) than those in unaffected gazelles. The activities in serum T-AOC, SOD, GSH-Px, and CAT in affected gazelles were extremely lower (p &lt; 0.01) than those in unaffected gazelles, while MDA was significantly higher (p &lt; 0.01) than that in unaffected gazelles. Supplementation in copper sulphate (CuSO4) has prevented and cured this disorder. In summary, high molybdenum in feed and soil may lead to secondary Cu deficiency in gazelles, which can be alleviated by supplement of copper sulfate.

Effects of Clinical Symptoms and Laboratory Values of COVID- 19 Patients' Tests at the Time of Hospitalization on Their Clinical Outcomes

Introduction: At the end of 2019, a new coronavirus caused pneumonia in Wuhan, China. Several studies have described the clinical features and immune manifestations in COVID-19 patients with moderate to severe symptoms, while their clinical relevance is less clear. This study investigates the effects of clinical symptoms and laboratory values of COVID-19 patients' tests at the time of hospitalization on their clinical outcomes. Methodology: This descriptive cross-sectional study was performed on COVID-19 patients hospitalized in Arak hospitals from April 2020 to March 2020. Medical records of all the hospitalized patients were retrieved. Trained personnel extracted general information (age and gender) and clinical profiles (the complete blood count and other required tests). Findings: Analyzing the laboratory indices of the blood count and LDH and CPK levels revealed a positive relationship between the patients' serum CPK levels, and the mortality rate (P = 0.001) and length of hospitalization (P = 0.015). Conclusion: The patients' serum LDH levels and fever were also associated with the mortality rate, and the need for mechanical ventilation, respectively. We hope this information helps physicians treat COVID-19 patients. Keywords: COVID-19, clinical symptoms, laboratory tests

Cellular Senescence and Vitamin D Deficiency Play a Role in the Pathogenesis of Obesity-Associated Subclinical Atherosclerosis: Study of the Potential Protective Role of Vitamin D Supplementation.

The exact link between obesity, vitamin D deficiency, and their relation to cellular senescence in the pathogenesis of subclinical atherosclerosis is still under debate. Therefore, the current study aims to verify the possible role of vitamin D deficiency and cellular senescence in the pathogenesis of obesity-related subclinical atherosclerosis. Moreover, it aims to investigate the possible protective role of vitamin D supplementation. Fifty-seven male albino rats were enrolled in the study and classified into four groups: negative (10) and positive control groups (10), an obese model group (24), and a vitamin-D-supplemented obese group (13). Aortic tissue samples and fasting blood samples were collected. The following biochemical investigations were performed: serum cholesterol, triglycerides, HDL-C, LDL-C, ALT, AST, CPK, CK-MB, and hs-cTnt. HOMA-IR was calculated. Moreover, serum SMP-30, 25 (OH)Vitamin D3, and eNOS were determined by the ELISA technique. Aortic gene expression of eNOS, SMP-30, and P53 was estimated by real-time qRT-PCR. Serum 25(OH) D3 and SMP-30 were lower in the obese group. In addition, the obese group showed higher serum lipid profile, HOMA-IR, eNOS, ALT, AST, CPK, CK-MB, and hs-cTnt than the control groups, while decreased levels were found in the vitamin-D-treated obese group. Gene expression of eNOS and SMP-30 were in accordance with their serum levels. A positive correlation was found between vitamin D level and SMP-30. In conclusion, obesity is associated with vitamin D deficiency and enhanced cellular senescence. They could play a role in the pathogenesis of obesity-associated subclinical atherosclerosis and endothelial dysfunction. Vitamin D supplements could play a protective role against such obesity-related comorbidity.

Rituximab for Inflammatory Myopathies in a Colombian Cohort.

Rituximab (RTX) is a treatment for refractory inflammatory myopathies, such as dermatomyositis (DM) and polymyositis (PM). This study describes the characteristics of patients receiving RTX for myositis in our institution to evaluate its efficacy. We collected demographic data from all patients diagnosed with DM or PM who received RTX between 2011 and 2018. Clinical and serological variables (including creatine phosphokinase [CPK] levels) were analyzed. Remission of disease was defined as no evidence of disease activity (active myositis) for longer than a 6-month continuous period while undergoing myositis therapy or no medication. Eighteen patients who had received first-line immunosuppressants were included. Fifteen (83%) had DM, 2 (11%) had PM, 1 had juvenile dermatomyositis, and 14 (77%) were women. All patients received glucocorticoids. Three patients (16.6%) were treated with RTX as monotherapy, and 15 (83.3%) were treated with RTX combined with other immunosuppressants. On average, there were 2 RTX treatment cycles. Improved muscular weakness was found in 13 cases (72%), and improved serum CPK levels were found in 15 cases (83%). Twelve patients (66%) achieved remission. Most patients experienced an objective improvement, as reflected in their serum CPK values and degree of muscular weakness. This suggests that RTX could be helpful in treating refractory myositis.

Tourniquet Use in Arthroscopic ACL Reconstruction: A Blinded Randomized Trial.

Despite knowing, that tourniquet induces ischemia and soft tissue damage surgeons still use it. The purpose of this study is to compare post operative pain and quadriceps function in patients undergoing arthroscopy assisted ACL reconstruction with tourniquet and without tourniquet. A blinded randomized prospective trial conducted at Orthopaedic department of a tertiary institute in India from Feb 2019 to June 2019. 45 patients undergoing Arthroscopic ACL reconstruction aged between 18 and 60years were recruited in the study according to selection criteria. Patients were distributed in 2 groups randomly, namely, tourniquet and non-tourniquet. Preoperatively serum CPK measurement and thigh girth measurement was done. Following standard arthroscopic procedure VAS score monitoring for pain was done for 5days. Serum CPK levels were performed on postoperative day 1. Thigh girth was measured on postoperative day 21. Pain was significantly high in patients in whom tourniquet was used. VAS scores were significantly high in tourniquet group. Tourniquet group patients required more amount of additional analgesics in postoperative period (p < 0.001). Serum CPK levels were comparable preoperatively while significantly high postoperatively in tourniquet group (p < 0.001). Difference in mean of thigh girth was significant between the groups (p < 0.001) and there is difficulty experienced by patients in performing straight leg raise test after tourniquet use (p = 0.002). Tourniquet use is associated with increased pain, analgesic requirement, damage to muscles and compromises muscle function in early postoperative period. This can not only lead to increased patient discomfort but also difficult initial rehabilitation. Arthroscopic procedures can be uneventfully performed without the use of a tourniquet, and alternative methods should be looked upon and emphasized.

Study of serum creatinine phosphokinase and serum lactate dehydrgenase as prognostic markers in organophosphorus poisoning

Background: Organophosphorus (OP) compounds are insecticides which are widely used in agriculture. Acute organophosphorus poisoning is an important cause of morbidity and mortality in developing countries like India. In a limited resourced country like India, we need cheap and easily measurable biomarkers for predicting prognosis.Objective was to estimate creatinine phosphokinase and serum lactate dehydrgenase as prognostic markers in acute organophosphorus poisoning.Methods: Total 94 cases of OP poisoning admitted to KIMS Hospital, Hubbali between January 1st 2017 to December 31th 2017 were studied. Detailed history, clinical examination and lab investigations like pseudo cholinesterase, serum LDH and serum CPK were carried out. Peradeniya OP poisoning scale was applied to all study subjects and the severity of OP poisoning was graded as mild, moderate, severe. Data obtained was analysed by different statistical methods.Results: OP poisoning is more common in adults of age group between 20 - 30 years, Incidence is was more in male patients, Mortality rate is 12.8%. Mean values of serum LDH, serum CPK were negatively correlated with pseudcholinesterase levels and it was statistically significant. Correlation between the severity of OP poisoning (based on Peradenyia score) and biochemical parameters like serum CPK, serum LDH, was statistically significant.Conclusions: The correlation between the severity of OP poisoning and biochemical parameters was statistically significant and they are usefull in predicting development of respiratory failure.

Directionally Opposite Effects Of Cyclosporine And Sirolimus On Endotoxic Nephrotoxicity In Rats

Immunosuppressant therapies have been shown to protect against inflammation, cardiovascular anomalies, and enhanced mortality during endotoxemia. The current study investigated whether end organ damage caused by endotoxemia is distinctly affected by calcineurin‐dependent (cyclosporine) and independent (sirolimus) immunosuppressants in rats. Biochemical, molecular, and histopathological studies were undertaken to determine the influence of simultaneous exposure to either immunosuppressant on renal and cardiac damage induced by endotoxemia. Serum biomarkers of kidney (urea, creatinine), but not heart (CPK), functions were significantly elevated in rats after 6 hr of treatment with lipopolysaccharide (LPS, 3 mg/kg i.p.). Moreover, LPS caused (i) vacuolation and degeneration of renal tubules, and (ii) significant increases in the width of proximal and distal tubules as appeared from morphometric analysis. Whereas these biochemical and histopathological influences of LPS were intensified upon concurrent exposure to cyclosporine (10 mg/kg i.p.), they were virtually eliminated after co‐treatment with sirolimus (1 mg/kg i.p.). Western expression studies demonstrated that increases in renal protein expressions of toll‐like receptor 4, monocyte chemoattractant protein‐1, and NADPH oxidase 2 were all potentiated and inhibited by cyclosporine and sirolimus, respectively. Unlike kidney data, the assessment of serum CPK or heart morphology revealed no evidence of cardiac abnormalities in rats treated with individual or combined LPS/immunosuppressant regimens. Together, the data underscore the capability of sirolimus, but not cyclosporine, to offset inflammatory and kidney damage in endotoxic states.

Effects of Nano-Copper Poisoning on Immune and Antioxidant Function in the Wumeng Semi-Fine Wool Sheep.

The Wumeng semi-fine wool sheep is vital to the production system of the Wumeng mountainous area in Southwest China. To study the effect of nano-copper poisoning in the Wumeng semi-fine wool sheep, nano-copper poisoning model was established in sheep. We determined blood physiological and biochemical parameters, immune indexes, and antioxidant indicators. The results showed that Hb, RBC, and PCV levels in blood from the nano-copper group were markedly lower (P < 0.01) than those in the control group. Serum LDH, AST, ALT, CPK, and Cp from the nano-copper group were significantly higher (P < 0.01) than those in control animals. Serum SOD, GSH-Px, CAT, and T-AOC from the nano-copper group were significantly lower (P < 0.01) than those in control sheep, and MDA content in serum from the nano-copper group were markedly higher (P < 0.01) than those in control sheep. The levels of IL-2, IL-6, IL-1β, IgA, IgM, and IgG from the nano-copper group were significantly lower (P < 0.01) than those in the control group. It was concluded that nano-copper poisoning could not only affect the immune function of Wumeng semi-fine wool sheep but also reduce the antioxidant capacity.

Evaluation of Glucosamine Effect Against Heart and Brain Damage Induced by Y-radiation or Aluminium Chloride in Female Rats

Abstract Glucosamine is known as anti-inflammatory, antioxidant and as neuroprotective as well as using to treat many of diseases. This work aimed to investigate the remedial effect of glucosamine (20mg/kg b.wt) against the damage induced by a single dose of γ-radiation (8Gy) or aluminium chloride (AlCl3) (100mg/kg b.wt) in the heart and brain tissues of female rats. Serum aspartate aminotransferase (AST), cholesterol, triglycerides (TGs), LDH and creatine kinase (CPK) were measured. Moreover, gene expression of amyloid protein precursor (APP) and seladin-1 were estimated in the brain tissue. Also, acetylcholinesterase activity (AChE) and p-tau protein expression were estimated in brain homogenate. Metallothioneine (MT) was estimated in the heart and brain tissues. Heart and brain histopathological examination was performed. Irradiation significantly decreased serum AST, CPK and LDH, as well as MT levels in heart and brain tissues. Also, gene expression of seladin-1 decreased. On the other hand, irradiation significantly increased serum TGs level and brain AchE activity, tau protein, and β-amyloid percursor (APP). AlCl3 administration (21 days) induced disturbance in most of the estimated parameters, especially AST, TGs, and MT. Glucosamine treatment with irradiation or AlCl3 improved most of the measured parameters. In addition, histopathological examination confirmed the biochemical results. In conclusion: Glucosamine could be used to improve the heart and brain damages induced by γ-radiation exposure or AlCl3.

366 Efficacy of mycotoxin deactivators on health and growth of newly weaned pigs under chronic dietary challenges of deoxynivalenol

Abstract The efficacy of mycotoxin deactivators on health and growth performance of newly weaned pigs (27 d-old) fed diets naturally contaminated with deoxynivalenol was investigated. Sixty pigs were housed individually and assigned to 5 treatments for 34 d subdivided into 3 phases: NC (no added deoxynivalenol); PC (deoxynivalenol at 2 mg/kg); CYC (PC + clay/yeast culture based product, 0.2%); CYE (PC + clay/yeast cell wall/plant extracts/antioxidants based product, 0.2%); and CYB (PC + clay/inactivated yeast/botanicals/antioxidants based product, 0.2%). Blood was taken at d 14 and 34. Intestinal mucosa was taken at d 34. Data were analyzed using Proc Mixed of SAS with pre-planned contrasts. Deoxynivalenol reduced (P &amp;lt; 0.05) ADG in P3. Pigs fed CYC had greater (P &amp;lt; 0.05) ADG during overall period, ADFI during P3, and gain/feed during P2 than PC. At d 14, deoxynivalenol reduced (P &amp;lt; 0.05) BUN/creatinine and tended to reduce (P = 0.088) BUN. Pigs fed CYB tended to have greater (P = 0.059) AST than PC. At d 34, pigs fed CYC (P = 0.083) and CYB (P = 0.068) tended to have lower serum CPK than PC. Pigs fed CYE had lower (P &amp;lt; 0.05) BUN/creatinine than PC. Deoxynivalenol tended to increase (P = 0.068) malondialdehydes and decrease (P = 0.072) glutathione in jejunal mucosa. Pigs fed CYE and CYB had lower (P &amp;lt; 0.05) malondialdehydes, whereas pigs fed CYB had greater (P &amp;lt; 0.05) glutathione and tended to have lower (P = 0.079) jejunal IgA than PC. Pigs fed CYC (P = 0.066) and CYE (P = 0.099) tended to have lower jejunal IL8 than PC. In conclusion, deoxynivalenol compromised growth performance and intestinal health. The mycotoxin deactivators could enhance intestinal health of pigs fed diets with deoxynivalenol without affecting liver function.
