Abstract Background: Hyperuricemia is the most important risk factor for gout, hypertension, coronary artery disease and other cardiovascular diseases. The incidence of hyperuricemia gradually increased in recent years and it is very necessary to explore the medications of the prevention and treatment of hyperuricemia using hyperuricemia animal models. Objective: The objective of present study is to explore the optimal dose of yeast extract and oteracil potassium in the establishment of hyperuricemia rat model. Method: Sixty-four male rats were randomly divided into 8 experimental groups. Rats were treated with yeast extract by intraperitoneal injection or yeast extract by intraperitoneal injection combined with various doses of oteracil potassium by intragastric feeding or intraperitoneal injection for 28 days. The serum uric acid, urea nitrogen and creatinine levels of different groups were measured at 0th day, 7th day, 14th day, 21th day and 28th day. Results: The serum levels of uric acid in the groups of intraperitoneal injection with yeast extract alone, yeast extract by intraperitoneal injection combined with 50-200 mg/kg oteracil potassium by intragastric feeding and yeast extract by intraperitoneal injection combined with 50-100 mg/kg oteracil potassium by intraperitoneal injection were higher than that in the control group. But we found no significant effect on rat kidney, heart or artery in the above groups. In the group of yeast extract by intraperitoneal injection combined with 200 mg/kg oteracil potassium by intraperitoneal injection, we observed the significantly high level of serum uric acid and morphological and pathological changes in rat kidney, heart and artery. Conclusion: In the present study, we found that continuously treated with yeast extract combined with oteracil potassium is an effective method to establish rat hyperuricemia model. Intraperitoneal injection of yeast extract combined with 200 mg/kg oteracil potassium is an optimal dosage for the construction of a persistent and stable hyperuricemia animal model.

Prediabetes is a glucose homeostasis condition characterized by decreased absorption to glucose or reduced fasting glucose. Both of these are reversible stages of intermediate hyperglycaemia providing an increased type II DM risk. Pre-diabetes can therefore be viewed as a significant reversible stage which could lead to type II DM, and early detection of prediabetes may contribute to type II DM prevention. Prediabetes patients are at high risk for potential type II diabetes, and 70 percent of them appear to develop Type II diabetes within 10 years. The present study includes total 200 subjects that include 100 Prediabetic patients, 50 T2DM patients and 50 healthy individual. Blood samples were collected from the subjects were obtained for FBS, PPBS, Uric acid and Creatinine estimation, from OPD and General Medicine Wards. Present study showed low levels of Serum Uric Acid in prediabetic and T2DM patients were decreased as compared to control group, while the level of creatinine in prediabetic and diabetic were elevated as compared to control group, were not statically significant. Serum Uric Acid was high in control group and low in prediabetic and diabetic patients. Serum creatinine was declined in control group and increased in prediabetic and diabetic patients with increasing Fasting blood glucose level.

To evaluate the antifertility effect of crude mixture of A. precatorius seeds at the dose level of 50 mg/kg body weight in adult male rats, after oral administration to male rats for 40 days, the rats were sacrificed and hormonal profiles, serum biochemistry, sperm count and histological changes were recorded. A sharp decrease in the serum levels of testosterone (0.70 ± 0.17 ng/ml), FSH (0.70 ± 0.22 lU/L), and LH (0.87 ± 0.35 IU/L) was detected compared to control (FSH, LH and testosterone levels 0.93 ± 0.15 ng/ml, 0.76 ± 0.28 IU/L, 1.44 ± .011 IU/L, respectively). A significant reduction of epididymal sperm count (2.34 million/mL) was noted in treated rats as compared to control group (7.87 million/mL). Histology of testes showed marked atrophy of the testes, which was characterized by disruption of the seminiferous epithelium and atrophy of the Leydig cells. Crude mixture of A. precatorius seed has a negative impact on male reproductive functions. It might be suggested that crude mixture of A. precatorius seeds might have antifertility property for male rats.   Keywords: Abrus precatorius; antifertility; male rat; testosterone.

BACKGROUND:Type 2 Diabetes Mellitus is a major non-communicable disease resulting from insulin resistance and is associated with cardiovascular,neurological and renal complications.Recent studies show association of hyperuricemia and Diabetes Mellitus.Uric acid increases oxidative stress that leads to vascular dysfunction and high intra glomerular pressure leading to renal complications.High serum creatinine is an indicator of renal compromise. OBJECTIVES: To evaluate serum uric acid and serum creatinine levels in type 2 diabetes mellitus patients and to find association between them. METHODOLOGY: The study was conducted in Osmania general hospital. Fifty cases of established Type 2 Diabetes Mellitus formed the study group and 50 normal healthy individuals formed the control group. Serum uric acid, Fasting Blood Glucose (FBS) and serum creatinine were estimated by colorimetric enzymatic methods on Beckman coulter AU5800.Mean values were compared in cases and controls using student t- test.Study group was further studied under 2 subgroups with serum Uric acid < 7 mg/dl and ≥7 mg/dl.In these 2 subgroups the association of Serum uric acid with FBS and creatinine was analysed statistically. RESULTS: Serum uric acid were found high in cases(7.63+/- 3.36)as compared to controls(4.48+/- 1.09) p value < 0.001.Serum creatinine were also high in cases(1.59+/- 1.39 )as compared to controls ( 0.87+/- 0.29) p value <0.005.Study subgroup with serum uric acid ≥7 mg/dl was associated with high creatinine and high fasting blood sugar levels when compared to subgroup with serum uric acid <7 mg/dl. CONCLUSION: Our study showed increased serum uric acid and serum creatinine levels in cases when compared to controls.There was significant association between high serum uric acid and high creatinine levels in cases.Therefore,it is important to measure serum uric acid and serum creatinine levels in diabetics for early detection of renal pathology.

Objectives: Psoriasis is a systemic chronic inflammatory autoimmune disease. Psoriasis can lead to multiple complications and co-morbidities. It has also been observed that raised serum uric acid levels predispose to gouty arthritis and also thought to be a risk factor for cardiovascular mortality and morbidity. The basic aim of this study was to ascertain level of serum uric acid in patients with chronic plaque psoriasis and control cases which might be a useful tool for assessing the extent and severity of chronic plaque psoriasis. Study Design: Case control study. Setting: At Outpatient’s Department (OPD) of Department of Dermatology, PNS Shifa, Karachi. Period: From January 2013 to December 2016. Material & Methods: One hundred and ninety four (194) patients were taken in this study and 97 patients were biopsy proven cases of psoriasis and 97 other participants included as control cases reporting to OPD with other complaint like acne, hair fall and fungal infections. After written and informed consent, 5ml of venous blood was drawn in sterile syringe and using gel sample tube to see the serum uric acid levels. On the basis of laboratory reports the elevated serum uric acid level in psoriatic versus normal controls was recorded on a pre-designed proforma. Results: There were 54.6% (106/194) male and 45.4% (88/194) female. Elevated serum uric level was 4.5 times (Approximate of 4.46) more common in cases than control group (OR: 4.46 95%CI: 1.83 to 10.91). Conclusion: Raised levels of serum Uric acid have been seen frequently in psoriatic patients. Early treatment for higher levels of serum uric acid might play a critical role in the better treatment of psoriatic patients. These results revealed that serum uric acid concentration (SUAC) of psoriasis may play a vital role in assessing the complex multifactorial etiology of the psoriasis, severity and other possible metabolic factors.

Background: Elevated levels of serum uric acid are associated with increased cardiovascular morbidity and mortality. However, this association with cardiovascular diseases is still unclear, and perhaps controversial. The objective of study was to assess the serum uric acid level in patients with Acute Myocardial Infarction (AMI).Methods: Sixty patients with AMI were studied in Department of Medicine/ Department of Cardiology, J.A. Group of Hospitals between 2016 -2018.Details of age, sex, smoking, alcohol consumption and history of ischemic heart disease (IHD) was obtained and recorded. Serum uric acid level was estimated and compared with control group (healthy subjects).Results: Serum uric acid level was significantly higher among AMI patients (6.43±2.60) as compared to control group (4.05±0.95) (p<0.001). Majority (46.7%) of the AMI patients had uric acid level of >7.1 followed by 20% patients who had uric acid level between 4.5-5.9 (p<0.001). Uric acid level was comparable between smoker and non-smokers (p=0.803), alcoholic and non-alcoholic (p=0.086), hypertensive and non-hypertensive (p=0.668), patients with and without diabetes (p=0.278) and patients with a history of IHD and without history of IHD (p=0.403).Conclusions: Serum uric acid may be useful for prognostication among those with pre-existing AMI.

Uric acid, an antioxidant, is reduced in multiple sclerosis (MS). Patients with gout have a reduced incidence of MS. O ptic neuritis (O N), often the first manifestation of MS, is not known to be associated with reduced uric acid. Patients with recent onset of O N were investigated to determine whether uric acid levels were reduced at presentatio n. Twenty-o ne patients with O N were included, 17 females and 4 males. The mean (SD) serum uric acid in the O N female group was 184.4 (±55.1) mmol/L (range, 116- 309 mmol/L), whilst in the control group it was 235.2 (±50.2) mmol/L (range, 172- 381 mmol/L). The difference was statistically significant (x2 = 8.93, P = 0.003). In the small male cohort, mean (SD) serum uric acid was 305 (±52.1) mmol/L, whilst in the control group it was 328 (±80.4) mmol/L. These differences were not statistically significant. Reduced antioxidant reserve is possibly an early patho genic mechanism in inflammatory demyelination, and raises the possibility that low uric acid levels could be an indicator of disease activity. Since optic neuropathies of other causes were not investigated, future research needs to determine whether low uric acid represents a unique feature of optic neuritis or is seen in other optic neuropathies.

Abstract Background Obesity is associated with insulin resistance, type2 diabetes, dyslipidemia and cardiovascular diseases. Apelin and chemerin are identified as adipokines and adipose tissue markers. Several adipose-derived peptides are known to influence food intake, including apelin, whose expression is regulated by insulin and chemerin. Oxidative stress thought to be involved in the development of complications associated with obesity. Objective To study the nature of correlation between serum and liver levels of apelin, chemerin and oxidative parameters in obese rats with and without antioxidant. Aiming to clarify the pathophysiology of obesity. Material and Methods Thirty adult male albino rats, divided into three equal groups. Group I (control), group II (obese) and group III (obese and Lepidium sativum (LS) as an antioxidants). At the end of the experiment, blood samples were collected for estimation of the serum levels of chemerin, apelin, fasting glucose, insulin, insulin resistance (IR), lipid profile, reduced glutathione (GSH) and malondialdehyde (MDA). In addition to tissue homogenous extracts of liver were taken for the levels of MDA, CAT, chemerin and apelin. Results After eight weeks, high fat diet group showed a significant increase in serum levels of apelin, chemerin, fasting glucose, insulin, IR, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) & MDA and a significant decrease in high-density lipoprotein cholesterol (HDL-C) & GSH. HFD also caused a significant increase in tissue levels of MDA, CAT & chemerin and a significant decrease in apelin, compared to control group. While addition of LS to HFD caused a significant decrease in serum levels of apelin, chemerin, fasting glucose, insulin, IR, TC, TG, LDL-C & MDA and a significant increase in HDL-C & GSH. LS also caused a significant decrease in tissue levels of MDA, chemerin & insignificant decrease in CAT and a significant increase in apelin, compared to HFD group. Conclusion This study showed a significant positive correlation between liver & serum chemerin and between liver and serum MDA. On the other hand, it showed a significant negative correlation between liver and serum apelin and liver CAT and serum GSH

Objective: To investigate the roles of serum uric acid (UA), bilirubin (BIL), albumin (ALB), and creatinine (CRE) as major intravascular antioxidants, in benign paroxysmal positional vertigo (BPPV).Methods: The serum levels of UA, BIL, ALB, and CRE were retrospectively analyzed in 70 patients with new-onset idiopathic BPPV and 140 age- and sex-matched healthy controls (HCs).Results: Serum UA, BIL, ALB, and CRE levels were significantly lower in the BPPV group than the HC group. Furthermore, serum levels of BIL and ALB were significantly lower in the BPPV group when compared by sex. Multiple stepwise logistic regression revealed that a reduction in serum ALB was independently related to BPPV (odds ratio = 0.688; 95% confidence interval = 0.607– 0.780). Receiver operating characteristic analyses revealed a cut-off value of 45.15 g/L for ALB with a sensitivity of 74.29% (62.97– 83.07%) and specificity of 73.57% (65.71– 80.18%).Conclusions: Serum levels of UA, BIL, ALB, and CRE were lower in BPPV patients, indicating a lower antioxidant status. Furthermore, a reduction in serum ALB was independently associated with BPPV. These results provide insights into the possible roles of oxidative stress in the pathogenesis of BPPV.
