Objective: The objective of our present study was to assess the role of serum amyloid A (SAA) in stages and prognosis of renal cell carcinoma. Material and Methods: It was a hospital based retrospective study carried out in the Department of Medicine and Biochemistry of Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January 2008 and $31^{st}$ December 2011. The variables collected were SAA, CRP. Approval for the study was obtained from the institutional research ethical committee. Quantitative analysis of human SAA and C-reactive protein (CRP) was performed by radial immune diffusion (RID) assay for all cases. Results: Of the 422 total cases of renal cell carcinoma, 218 patients had normal and 204 abnormal SAA. SAA levels were grossly elevated in T3 stage ($122.3{\pm}SD35.7$) when compared to the mean for the T2 stage ($84.2{\pm}SD24.4$) (p value: 0.0001). Similarly, SAA levels were grossly elevated in M1 stage ($190.0{\pm}SD12.7$) when compared to the M0 stage ($160.9{\pm}SD24.8$) (p: 0.0001). There was no significant association with elevated CRP levels ($209.1{\pm}SD22.7$, normal $199.0{\pm}SD19.5$). Conclusion: The validity of SAA in serum as being of independent prognostic significance in RCC was demonstrated with higher levels in advanced stage disease.

The Cholangiocarcinoma is a. The risk of development of cholangiocarcinoma, generally a rare type of a liver tumor, increases during infection of Opisthorchiasis. For this reason the timely detection of Opisthorchiasis is important for Cholangiocarcinoma prevention. There are many studies which concern the detection of pathogenesis of Opisthorchis viverrini infection but a little known about Opisthorchis felineus. In this study we investigate a correlation of the eggs which are found in a faeces and are comparable with a serum Ig G and Ig M antibody level that were detected with ELISA test in a large group of patients. The result is showing positive correlation between evidence of the Opisthorchis felineus eggs that were found in a faeces and antibody Ig G and Ig M level in a serum. Moreover the combination of two methods can improve the Opisthorchiasis diagnostic: the serum antibody and faeces investigation of eggs.

Aims and Background: Human leukocyte antigen-G and interleukin-2 receptor play pivotal roles in the proliferation of lymphocytes, and thus generation of immune responses. Their overexpression has been evidenced in different malignant hematopoietic diseases. This study aimed to validate serum soluble human leukocyte antigen-G (sHLA-G) and serum soluble interleukin-2 receptor (sIL-2R) as an additional tool for the diagnosis and follow up of acute lymphoblastic leukemia (ALL). Subjects and Methods: Both markers were determined by ELISA in the serum of 33 ALL pediatric patients before treatment and after intensification phase of chemotherapy as well as in the serum of 14 healthy donors that were selected as a control group. Results: ALL patients showed abnormal CBC and high serum lactate dehydrogenase, which were improved after chemotherapy. Also, there was a non-significant increase in serum sHLA-G in ALL patients compared with the control group. However, after chemotherapy, sHLA-G was increased significantly compared with before treatment. On the other hand, serum sIL-2R in ALL patients was increased significantly compared with the control group. After chemotherapy, sIL-2R decreased significantly compared with before treatment. Conclusions: From these results it could be suggested that measurement of serum sHLA-G might be helpful in diagnosis of ALL, while sIL-2R might be useful in diagnosis and follow-up of ALL in pediatric patients.

The objective of this study was to determine the safety test for propolis in Beagle based on blood count, serum biochemistry, and electrolyte. Total six beagle dogs were assigned to this experiment. To investigate the safety of propolis in beagle dogs, we performed oral administration of propolis (5%) for 8 weeks. Among six beagles, three beagle dogs were randomly allocated to the control group which were fed only regular fodder, and the other three dogs were assigned as the treatment group which were fed regular fodder and propolis (5%). No clinical signs were observed in neither group throughout the experimental period. During the experimental period, there were no significant change in feed intake, water consumption, and body condition. Also, there were no statistically significant differences in hematological and biochemical analyses between the control group and the treated group. Our safety study showed that oral consumption of propolis did not cause any toxicological effects in beagle dogs.

Background: Vitamin D is known to have diverse effects on various systems in the body. There is evidence to suggest that a link exists between the serum vitamin D status and tuberculosis. The present study was designed to assess the alterations in serum 25-hydroxyvitamin D levels in newly diagnosed sputum acid fast bacilli (AFB) positive pulmonary tuberculosis patients and to study the association, if any, between serum vitamin D levels and different levels of sputum smear positivity. Methods: Serum 25-hydroxyvitamin D levels were estimated in 65 sputum AFB positive pulmonary tuberculosis patients and 65 age and gender-matched healthy controls. Results: The levels of serum 25 hydroxy-vitamin D in tuberculosis patients were not statistically different from the levels of serum 25 hydroxy-vitamin D in healthy controls. However, among patients with pulmonary tuberculosis, there was a significant negative correlation between the levels of serum 25 hydroxy-vitamin D and levels of sputum positivity. Conclusion: Serum vitamin D levels negatively correlates with bacterial load in patients with active pulmonary tuberculosis.

Background: Serum concentration of cystatin C, a marker of glomerular filtration has been associated with cardiovascular disease (CVD). The aim of this study was to evaluate cystatin C as a marker of obese patients without chronic kidney disease (CKD). Materials and Methods: The study population consisted of 36 subjects with metabolic syndrome and 32 subjects free of metabolic syndrome (the control group). HDL-C, LDL-C, blood urea, triglycerides, glucose, HbA1c, serum cystatin C and serum creatinine were measured in both groups. GFR was calculated in both groups using Cockroft-Gault equation. Results: Obese patients showed higher cystatin C levels than normal samples ($1.28{\pm}0.29$, P < 0.05). In the binary logistic regression, obese patients were significantly associated with elevated cystatin C levels. Conclusion: Our results suggest that cystatin C may be a marker for obese patients and may identify a certain degree of renal dysfunction even when serum creatinine does not exceed the normal level. In this study, we demonstrated that serum creatinineand GFR did not differ significantly between the diabetic and the control groups. Serum concentration of cystatin C was significantly higher in the diabetic group compared with the control group. The strengths of this study are the evaluation of reliability and sensivity in comparison with a 'routine test of GFR'. The methodology used allows an appropriate statistical comparison of reliability in contrast to most other previous evaluations of GFR.

Aim: To investigate the effect of hyperglycemia and hyperinsulinemia on prostate cancer risk. Materials and Methods: This hospital based study was carried out using data retrieved from the register maintained in the Department of Biochemistry of a tertiary care hospital of Kathmandu, Nepal between $31^{st}$ December, 2011 and $31^{st}$ October, 2013. The variables collected were age, serum cholesterol, serum calcium, PSA, fasting blood glucose, serum insulin. Analysis was performed by descriptive statistics and testing of hypothesis using Excel 2003, R 2.8.0, Statistical Package for the Social Sciences (SPSS) for Windows Version 16.0 (SPSS Inc; Chicago, IL, USA) and the EPI Info 3.5.1 Windows Version. Results: Of the total 125 subjects enrolled in our present study, 25 cases were of PCa and 100 were healthy controls. The mean value of fasting plasma glucose was 95.5 mg/dl in cases of prostatic carcinoma and the mean value of fasting plasma insulin was $5.78{\mu}U/ml$ (p value: 0.0001*). The fasting insulin levels ${\mu}U/ml$ were categorized into the different ranges starting from ${\leq}2.75$, >2.75 to ${\leq}4.10$, >4.10 to ${\leq}6.10$, > $6.10{\mu}U/ml$. The maximum number of cases of prostatic carcinoma of fasting insulin levels falls in range of > $6.10{\mu}U/ml$. The highest insulin levels (> $6.10{\mu}U/ml$) were seen to be associated with an 2.55 fold risk of prostatic carcinoma when compared with fasting insulin levels of (< $2.75{\mu}U/ml$). Conclusions: Elevated fasting levels of serum insulin appear to be associated with a higher risk of prostate cancer.

Background: Lipemia, a significant source of analytical errors in clinical laboratory settings, should be removed prior to measuring biochemical parameters. We investigated whether lipemia in serum/plasma samples can be removed using a method that is easier and more practicable than ultracentrifugation, the current reference method. Methods: Seven hospital laboratories in Spain participated in this study. We first compared the effectiveness of ultracentrifugation ($108,200{\times}g$) and high-speed centrifugation ($10,000{\times}g$ for 15 minutes) in removing lipemia. Second, we compared high-speed centrifugation with two liquid-liquid extraction methods-LipoClear (StatSpin, Norwood, USA), and 1,1,2-trichlorotrifluoroethane (Merck, Darmstadt, Germany). We assessed 14 biochemical parameters: serum/plasma concentrations of sodium ion, potassium ion, chloride ion, glucose, total protein, albumin, creatinine, urea, alkaline phosphatase, gamma-glutamyl transferase, alanine aminotransferase, aspartate-aminotransferase, calcium, and bilirubin. We analyzed whether the differences between lipemia removal methods exceeded the limit for clinically significant interference (LCSI). Results: When ultracentrifugation and high-speed centrifugation were compared, no parameter had a difference that exceeded the LCSI. When high-speed centrifugation was compared with the two liquid-liquid extraction methods, we found differences exceeding the LCSI in protein, calcium, and aspartate aminotransferase in the comparison with 1,1,2-trichlorotrifluoroethane, and in protein, albumin, and calcium in the comparison with LipoClear. Differences in other parameters did not exceed the LCSI. Conclusions: High-speed centrifugation ($10,000{\times}g$ for 15 minutes) can be used instead of ultracentrifugation to remove lipemia in serum/plasma samples. LipoClear and 1,1,2-trichlorotrifluoroethane are unsuitable as they interfere with the measurement of certain parameters.
