Abstract
BACKGROUND Bone tumors are responsible for considerable morbidity and mortality at an early age. Malignant bone tumors are quite aggressive in nature. Thus, an accurate and timely diagnosis is essential for bone tumors. Neutrophil gelatinase associated lipocalin (NGAL) and vitamin D have been found to be associated with cancer and may have potential to act as biomarkers for bone tumors also. METHODS Serum levels of NGAL and 25-OH vitamin D were estimated in 14 patients with benign and 14 with malignant bone tumors and compared with 14 apparently healthy controls. The data collected was compared among different groups using appropriate statistical analysis. NGAL was estimated by enzyme linked immunosorbent as-say (ELISA) and 25-OH vitamin D by radioimmunoassay (RIA) in the serum samples. RESULTS Serum NGAL levels were found to be increased significantly and 25-OH vitamin D levels decreased significantly in patients with malignant bone tumors as compared to healthy controls (p < 0.001) while this difference was not statistically significant in patients with benign bone tumors (p = 0.05). The difference in serum levels of NGAL and 25-OH vitamin D in patients with malignant bone tumors was found to be statistically significant as compared to patients with benign bone tumors (p < 0.05). The correlation was not statistically significant between the levels of 25-OH vitamin D and NGAL in group I (r = 0.067, p = 0.819), group II (r = 0.204, p = 0.483), and group III (r = -0.086, p = 0.772). CONCLUSIONS Serum NGAL and 25-OH vitamin D may be used as important serological biomarkers in patients with bone tumors along with other standard investigative modalities.

Abstract
INTRODUCTION Neutrophil gelatinase-associated lipocalin (NGAL) has been reported to be unregulated in many cancers and to suppress tumor suppressor genes like p53 leading to cell proliferation. Studies to report its relationship with carcinoma cervix (Ca Cx) are still scant. MATERIALS AND METHODS Serum NGAL levels were analyzed in 30 patients of histopathologically proven locally advanced Ca Cx at the time of diagnosis and 3 weeks after standard chemoradiation by enzyme-linked immunosorbent assay. These patients underwent either brachytherapy or supplementary external beam radiotherapy (EBRT) depending on the response of treatment. The results were analyzed statistically by applying Student's paired t-test. RESULTS No statistically significant difference (P > 0.05) was observed in patients of Ca Cx before and after treatment or when compared stage wise, histopathological grade wise, or response wise. But the levels were found to increase when duration of treatment was ≥8 weeks (P = 0.040) and to decrease significantly when duration of treatment was <8 weeks (P = 0.0052). The NGAL levels also increased significantly after treatment in patients who received EBRT and supplementary radiotherapy (P = 0.019) while the pre- and post-treatment difference in NGAL levels was not statistically significant in patients who received EBRT + intracavitary brachytherapy (P > 0.05). CONCLUSION As the duration as well as modality of treatment is quite important in Ca Cx, shorter duration associated with better results and lower NGAL levels, NGAL might prove to be a useful biomarker although further studies are needed to support the claim.

Abstract
BACKGROUND Menopause and hypothyroidism, both individually, affect the reproductive hormone profile as well as body metabolism which is reflected in the form of a deranged biochemical profile. It will be interesting to observe the effects on both these profiles, when menopause is associated with hypothyroidism. METHODS This study was conducted on 30 postmenopausal women with newly diagnosed primary hypothyroidism and 30 euthyroid menopausal females as controls. Serum samples of all the subjects were analyzed for complete thyroid profile including total T3 (TT3), total T4 (TT4), free T3 (FT3), free T4 (FT4), thyroid stimulating hormone (TSH), estradiol, progesterone, fasting glucose, renal function tests, liver function tests, and lipid profile. Data of both the groups was compared using Student's t-test. RESULTS There was no statistically significant difference observed between the fasting glucose levels and renal and liver function tests in both the groups (p > 0.05). Serum triglycerides, total cholesterol, low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) were found to be significantly increased (p < 0.05) while high density lipoprotein cholesterol (HDL-C), estradiol, and progesterone were found to be significantly decreased (p < 0.05) in menopausal hypothyroid women as compared to their euthyroid counterparts. CONCLUSIONS Thus, an association of both menopause and hypothyroidism may lead to accentuation of effect of each on biochemical and reproductive hormone profile.

Abstract
BACKGROUND Mortality due to lung cancer is one of the growing concerns worldwide. Accurate and timely diagnosis is the key to treatment of this disease. Neutrophil gelatinase associated lipocalin (NGAL) and vitamin D have been found to be associated with cancer and may have potential to act as biomarkers for lung cancer. METHODS Serum levels of NGAL and 25 hydroxy vitamin D (25OH vitamin D) were estimated in 25 patients with lung cancer before (Group I) and 4 weeks after standard treatment (Group II) by chemoradiation. The levels were also analyzed in 25 apparently healthy controls and data was compared among different groups using appropriate statistical analysis. NGAL was estimated by enzyme linked immunosorbent assay (ELISA) and 25OH vitamin D by radioimmunoassay (RIA) in the serum samples. RESULTS Serum NGAL levels were found to be increased significantly in patients before treatment as compared to healthy controls (p < 0.001) while the levels decreased significantly after treatment (p < 0.01). The levels of vitamin D were found to be decreased in lung cancer patients as compared to healthy controls (p < 0.05) while after treatment the levels of vitamin D were found to be significantly increased (p < 0.001). The correlation was not statistically significant between the levels of vitamin D and NGAL in Group I (r = 0.12, p = 0.57), Group IIa (r = 0.037, p = 0.86), and Group IIb (r = 0.091, p = 0.66). CONCLUSIONS Serum NGAL and vitamin D bear the potential to act as biomarkers in patients with lung cancer.

Abstract
INTRODUCTION Vitamin D has been shown to play a vital role in bone mineral homeostasis by stimulating the intestinal absorption of calcium and phosphate. The critical role of Vitamin D in bone metabolism triggered the need to evaluate the effect of Vitamin D deficiency and hence replacement of the same on osseointegration of dental implants. This prospective study evaluated the crestal bone level in patients having low level of Vitamin D treated with dental implant with or without Vitamin D3 supplements. MATERIALS AND METHODS A prospective clinical study was conducted on 32 patients based on the inclusion and exclusion criteria. Patients were divided into two groups on the basis of Vitamin D level < 30 ng/ml (Group I: patients receiving Vitamin D3 supplements, i.e., cholecalciferol 1 g sachet 60,000 IU/month) or <30 ng/ml (Group II: not receiving Vitamin D3 supplements). The crestal bone level measurements were made with the help of Digimizer Image Analysis, MedCalc software. RESULTS All implants showed clinically acceptable crestal bone level at interval of 1 week (baseline), 3 months, and 6 months. There was a statistically nonsignificant difference seen for the values between the groups (P > 0.05) for all other values at various time intervals. However, there was a statistically significant/highly significant difference seen for the values between the groups (P < 0.01, 0.05) for 3 months distal with higher values for Group I as compared to Group II. CONCLUSION From the study, it can be concluded that cholecalciferol has systemic effects on accelerating bone formation around titanium implant.

Abstract
Background:Ischemia Modified Albumin (IMA) is considered as an early marker of ischemia. Its levels may be altered in any clinical condition where an ischemic event is involved. Skeletal muscle ischemia is associated with severe exercise but may also occur in moderate form of exercise.Objective:The levels of IMA were estimated before and after thirty minutes of moderate exercise in students undergoing athletic training.Methods:The present study was conducted on 120 young adult students undergoing athletic training program in the physical education department. All the subjects were healthy with normal body mass index and blood pressure. Their serum samples were collected before and after running for half an hour on the racing track and were analyzed for IMA colorimetrically and the data was subjected to appropriate statistical analysis.Results:The levels of IMA were found to be statistically significantly higher after exercise as compared to those before exercise (p = 0.005). The ratio of IMA to albumin (IMAR) was also found to be significantly higher after exercise as compared to that before exercise (p=0.000).Conclusion:It may be concluded that the skeletal muscle ischemia induced by moderate aerobic exercise is associated with an increased conversion of albumin to IMA.

Abstract
AIM To study sigma metrics and quality goal index ratio (QGI).
METHODS The retrospective study was conducted at the Clinical Biochemistry Laboratory, PGIMS, Rohtak, which recently became a National Accreditation Board for Testing and Calibration of Laboratories accredited lab as per the International Organization for Standardization 15189:2012 and provides service to a > 1700-bed tertiary care hospital. Data of 16 analytes was extracted over a period of one year from January 2017 to December 2017 for calculation of precision, accuracy, sigma metrics, total error, and QGI.
RESULTS The average coefficient of variation ranged from 2.12% (albumin) to 5.42% (creatinine) for level 2 internal quality control and 2% (albumin) to 3.62% (high density lipoprotein-cholesterol) for level 3 internal quality control. Average coefficient of variation of all the parameters was below 5%, reflecting very good precision. The sigma metrics for level 2 indicated that 11 (68.5%) of the 16 parameters fall short of meeting Six Sigma quality performance. Of these, five failed to meet minimum sigma quality performance with metrics less than 3, and another six just met minimal acceptable performance with sigma metrics between 3 and 6. For level 3, the data collected indicated eight (50%) of the parameters did not achieve Six Sigma quality performance, out of which three had metrics less than 3, and five had metrics between 3 and 6. QGI ratio indicated that the main problem was inaccuracy in the case of total cholesterol, aspartate transaminase, and alanine transaminase (QGI > 1.2), imprecision in the case of urea (QGI < 0.8), and both imprecision and inaccuracy for glucose.
CONCLUSION On the basis of sigma metrics and QGI, it may be concluded that the Clinical Biochemistry Laboratory, PGIMS, Rohtak was able to achieve satisfactory results with world class performance for many analytes one year preceding the accreditation by the National Accreditation Board for Testing and Calibration of Laboratories. Aspartate transaminase and alanine transaminase required strict external quality assurance scheme monitoring and modification in quality control procedure as their QGI ratio showed inaccuracy.

Abstract
AIM To study the levels of neutrophil gelatinase associated lipocalin (NGAL) in head and neck squamous cell carcinoma (HNSCC).
METHODS This was a non randomized case control study conducted at Department of Biochemistry, in collaboration with Regional Cancer Center over a period of one year. The study population included 50 adult newly diagnosed HNSCC patients reporting in outpatient department at Regional Cancer Center and compared with 50 healthy controls. NGAL was estimated by ELISA technique. Student t test and χ2 test were applied for comparison of means of study groups. Correlations between groups were analyzed using Pearson correlation coefficient (r) formula.
RESULTS Patients with HNSCC exhibited significantly increased levels of NGAL (P < 0.05) as compared to healthy controls (978.88 ± 261.39 ng/mL vs 34.83 ± 7.59 ng/mL). Out of 50, 26 patients (52%) were in stage IV, 21 (42%) in stage III, 1 (2%) patient in stage II and 2 (4%) patients were in stage I. Metastasis was absent in 98% patients and mean NGAL levels were highest in these patients but P value was not significant. Mean NGAL levels were highest in stage IV [1041.54 ± 222.15 ng/mL (stage IV) vs 1040 ± 0.00 ng/mL (stage I); 900 ± 0.00 ng/mL (stage II) and 1031.90 ± 202.55 ng/mL (stage III)] and χ2 test was highly significant (P < 0.001). Thirty-six patients (72%) were having moderately differentiated HNSCC and mean NGAL levels were maximum in patients with well differentiated HNSCC (1164 ± 315.64 ng/mL vs 1013.33 ± 161.19 ng/mL in moderately differentiated and 890 ± 11.55 ng/mL in poorly differentiated) and the results were also highly significant (P < 0.001, χ2 test).
CONCLUSION The present work demonstrates a potential role of NGAL as cancer biomarker and its use in monitoring the HNSCC progression.

Abstract
Squamous cell cancer is the most common type of malignancy arising from the epithelial cells of the head and neck region. Head and neck squamous cell carcinoma (HNSCC) is one of the predominant causes of cancer related casualties worldwide. Overall prognosis in this disease has improved to some extent with the advancements in therapeutic modalities but detection of primary tumor at its initial stage and prevention of relapse are the major targets to be achieved for further improvement in terms of survival rate of patients. Latest achievements in basic research regarding molecular characterization of the disease has helped in better perception of the molecular mechanisms involved in HNSCC progression and also in recognizing and targeting various molecular biomarkers associated with HNSCC. In the present article, we review the information regarding latest and potential biomarkers for the early detection of HNSCC. A detailed molecular characterization, ultimately, is likely to improve the development of new therapeutic strategies, potentially relevant to diagnosis and prognosis of head and neck cancers. The need for more accurate and timely disease prediction has generated enormous research interests in this field.

Abstract
OBJECTIVE Pre-eclampsia is associated with ischemia and increased oxidative stress, which may lead to modification of plasma albumin to ischemia modified albumin (IMA). METHODS IMA levels were estimated in cord blood of 30 newborns born to pre-eclamptic mothers and compared with 30 normal newborns. IMA was estimated colorimetrically and the results were compared statistically. RESULTS The levels of IMA were found to be significantly higher (p < 0.001) in newborns born to pre-eclamptic mothers (0.835 ± 0.02 ABSU) as compared to those born to normal mothers (0.325 ± 0.01 ABSU). CONCLUSION IMA may act as a marker of ischemia and oxidative stress in newborns delivered to pre-eclamptic mothers.

Abstract
Multiple animal studies, few clinical case reports and one study have observed decreased testosterone production and gynaecomastia as adverse effect of imatinib therapy. We have prospectively studied testosterone, LH and FSH levels at baseline and at 6 months of imatinib treatment in 34 newly diagnosed male BCR-ABL positive CML patients. While none of the patients had gynaecomastia at 6 months, the proportion of patients with low testosterone level increased significantly from 11.8% at baseline to 58.8% (p < 0.001) and those with high LH and FSH increased significantly from 26.4% and 23.5% to 82.4% and 76.4%, respectively (p < 0.001 and p < 0.001). Serum testosterone levels decreased significantly (p = 0.002) and serum LH and FSH levels increased significantly at 6 months of imatinib therapy (p = 0.001 and p = 0.003) in comparison to baseline levels. The findings document the effect of imatinib on testosterone levels in adult CML patients much before than reported earlier.

Abstract
BACKGROUND Chronic myelogenous leukemia (CML), a myeoloproliferative disorder, is characterized by the presence of the fusion gene BCR-ABL in hematopoietic cells. Leptin, considered a link between cancer and obesity, has been reported to be actively involved in hemopoiesis and pathophysiology of CML. There are few and conflicting reports about the status of serum leptin levels and recently alteration in leptin has been reported due to imatinib mesylate. METHODS Leptin and CRP were estimated in 30 (male: 20; female: 10) newly diagnosed and confirmed MBCR- ABL p210 positive CML patients before and after 3 months of therapy by commercial enzyme linked immunosorbent assays. Leptin levels were compared with 30 (male: 20; female: 10) age matched healthy controls accounting for the differences due BMI and gender. RESULTS Leptin/BMI ratio was significantly raised in both male and female chronic phase patients as compared to controls (p < 0.001, p = 0.048) and accelerated phase patients as compared to controls (males, p < 0.001; females, p < 0.001). The normal gender difference and dependence on BMI was lost in patients. In patients, who failed to achieve hematological baseline, leptin/BMI was higher only in male patients (p = 0.012). Leptin/BMI also correlat- ed with TLC and blast percentage (TLC, R2 = 0.412, p = 0.001; Blast %, R2 = 0.408, p < 0.001). There was no correlation between leptin and CRP levels. Levels decreased significantly after complete hematological remission in both males and females (p = 0.001, p = 0.028). Levels after 3 months of imatinib therapy were significantly higher than controls in all patients not in remission (males, p < 0.001; females, p = 0.018) but only in male patients in re- mission (p = 0.002). CONCLUSIONS Leptin levels were increased in CML patients. The findings suggest a possible role of leptin in patho- genesis of CML or disease progression independent of inflammatory state or reactionary rise. Imatinib itself may increase leptin levels, and, as leptin plays an active role in the pathophysiology of CML, this conflicting scenario needs further investigation. Alterations in leptin need to be investigated cautiously accounting for confounding and differences due to BMI and gender.

Abstract
BACKGROUND Thyroid disorders especially hypothyroidism is associated with increased generation of oxidants. Nitric oxide and ischemia modified albumin are considered markers for oxidative stress. In addition, nitric oxide is involved in regulation of thyroid function and coagulation profile alteration in thyroid disorders may produce ischemia like conditions. METHODS Nitric oxide and ischemia modified albumin were estimated in fifty patients of newly diagnosed hypothyroidism using standard photocolorimetric techniques. Results were compared with fifty healthy euthyroid controls and subjected to appropriate statistical analysis. RESULTS Nitric oxide and ischemia modified albumin were found to be significantly raised (p < 0.05) in hypothyroid patients as compared to controls. A positive, but statistically insignificant correlation was observed between nitric oxide and ischemia modified albumin. CONCLUSIONS Estmation of nitric oxide and ischemia modified albumin in hypothyroidism may help to throw light on its pathogenesis and assessing the severity of the disease, though further research is needed to establish their role as biomarkers in hypothyroidism.

Abstract
Nitric oxide (NO) is involved in different stages of malignancies. Increased levels of NO have been reported in different leukemias. Imatinib is the preferred drug for the treatment of chronic myeloid leukemia (CML). Turmeric powder contains curcumin which has anti-leukemic property and also decreases NO synthesis. This study was conducted on fifty patients of CML divided into two groups, group A receiving imatinib alone and group B receiving turmeric powder along with imatinib for six weeks. Nitric oxide levels were estimated in these patients before and after receiving therapy and were analyzed statistically. Nitric oxide levels were found to be significantly decreased in both the groups, but more significantly in group B after receiving the respective treatments. Thus, curcumin acts as an adjuvant to imatinib in decreasing the NO levels and may help in the treatment of CML patients.

Abstract
BACKGROUND Placenta accreta is a rare obstetrical condition that mainly occurs in the third trimester leading to life-threatening complications. Hereby, a case of uterine rupture due to placenta accreta occuring in the second trimester is presented. CASE PRESENTATION A forty-year old patient who conceived after in vitro fertilization treatment (oocyte donation and embryo transfer) presented in emergency department in the nineteen weeks of gestation with acute abdominal pain, heamoperitoneum and fetal death. Emergency laprotomy showed uterine rupture along with placenta accreta for which the patient underwent subtotal hysterectomy. CONCLUSION Although, an uncommon occurrence, physicians in assisted reproductive techniques (ART) clinics should consider placenta accreta in gravid patients who present with acute abdominal pain and shock, considering the fact that they usually have associated high risk factors for abnormal placentation.

Abstract
OBJECTIVES The mainstay of the treatment of head and neck squamous cell carcinoma (HNSCC) is radiotherapy, which acts by producing free radicals. Therefore, this study was planned to observe the effect of radiotherapy on oxidative stress in patients of HNSCC. METHODS This study was conducted on 50 histopathologically proven cases of HNSCC. The levels of nitric oxide, glutathione-S-transferase, and vitamin C were estimated colorimetrically before and after treatment in patients and in 30 age- and sex-matched healthy controls. The results were compared statistically. RESULTS The levels of nitric oxide and glutathione-S-transferase were significantly higher in patents as compared to controls and increased significantly after treatment. Vitamin C levels were significantly lower in patients as compared to controls and decreased significantly after treatment. CONCLUSIONS HNSCC leads to increased oxidative stress and treatment in the form of radiotherapy itself produces an accentuation of this stress.

Abstract
CONTEXT Ocimum sanctum has been reported to have a variety of medicinal properties. OBJECTIVE The present study was planned to evaluate the effect of O. sanctum on plasma homocysteine levels and lipid profile in healthy rabbits. MATERIAL AND METHODS Forty rabbits were divided into two groups (20 each). Group I rabbits received normal diet and group II rabbits received fresh leaves of O. sanctum (2 g/day) for 8 weeks along with normal diet. Fasting plasma samples were estimated for homocysteine and lipid profile. The results were analysed statistically. RESULTS The levels of homocysteine, total cholesterol, triglycerides, low density lipoprotein cholesterol, very low density lipoprotein cholesterol were found to be decreased and high density lipoprotein cholesterol levels increased significantly on supplementation with O. sanctum (p < 0.001). DISCUSSION AND CONCLUSION Thus, O. sanctum can prove to be a significant cardioprotective substance and an important adjuvant in the treatment of hyperhomocysteinemia and dyslipidemia.

Abstract
BACKGROUND Carcinomas are considered to be associated with increased cellular proliferation under antigenic stimulation and inflammation. Therefore, the markers of increased cellular turnover such as adenosine deaminase and uric acid were estimated quantitatively along with markers of inflammation such as C-reactive protein in squamous cell carcinoma of head and neck region. METHODS The levels of adenosine deaminase, uric acid, and C-reactive protein were estimated in 50 patients of squamous cell carcinoma of head and neck region before starting any treatment and compared with their corresponding levels in 30 healthy age and gender matched controls. The patients were divided into four groups depending on their staging and their results were compared statistically and the coefficient of correlation was calculated using Pearson's formula. RESULTS The levels of adenosine deaminase, uric acid, and C-reactive protein were found to be significantly higher in patients of head and neck cancers as compared to the levels in controls (p < 0.001). The levels were also observed to rise with staging. A positive correlation was observed between adenosine deaminase and uric acid (r = 0.743, p < 0.001), adenosine deaminase and C-reactive protein (r = 0.648, p < 0.001) and also between C-reactive protein and uric acid (r = 0.712, p < 0.001). CONCLUSIONS Thus, estimation of adenosine deaminase, uric acid, and C-reactive protein can help in making the diagnosis and assessing the severity of disease in patients of head and neck carcinoma.

Abstract
BACKGROUND High levels of glycated hemoglobin (HbA(1c)) have been associated with Coronary Vascular Diseases (CVD) in diabetic patients. Recent studies have reported no association between elevated glycated hemoglobin (HbA(1c)) and incident cardiovascular disease (CVD) among women without diabetes. There are many controversial studies on topics such as "Glycated hemoglobin levels (HbA(1c)) have been associated with cardiovascular diseases (CVD) in the non-diabetic patients". Therefore, we planned this study. METHODS The present study was conducted on 50 age matched controls and 50 clinically diagnosed non-diabetic CVD patients of either gender. The study included 50 patients with myocardial infarction (MI) admitted to the ICCU ward of J.L.N. Medical College and Hospital, Ajmer (Rajasthan). The following information was recorded from admission sheets of non-diabetic CVD patients of either gender: history of diabetes, hypertension, and cigarette smoking; demographic indices; coronary heart disease and diabetes mellitus treatment; serum cholesterol; serum triglycerides (TG); high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C); fasting and non-fasting blood glucose levels and Glycated haemoglobin levels (HbA(1c)). Glycosylated hemoglobin (HbA(1c)) was measured by latex agglutination inhibition assay. RESULTS AND CONCLUSIONS The HbA(1c) levels in healthy controls (n = 50) and non-diabetic CVD subjects (n = 50) observed were 4.32 +/- 0.34% and 5.80 +/- 0.20%, respectively. HbA(1c) levels in these subjects were significantly higher than controls (p < 0.001). The HbA(1c) levels in non-diabetic CVD patients are higher in comparison to controls.

Abstract
Fresh leaves of Ocimum Sanctum (OS) were used to study its effect on male reproductive function (sperm count and reproductive hormones) in male albino rabbits. Animals in the test group received supplementation of 2 g of fresh leaves of OS per rabbit for 30 days, while the control group was maintained on normal diet for the same duration. Sperm count and hormonal estimation [testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH)] were done in serum samples of both groups and compared. A significant decrease was noted in the sperm count in test group rabbits. Serum testosterone levels showed marked increase while FSH and LH levels were significantly reduced in OS-treated rabbits. The results suggest the potential use of OS as an effective male contraceptive agent.

Abstract
Wheat grass is used as a general health tonic and is reported to be effective against several medical disorders, although detailed literature is not available. Besides drug therapy, a number of medicinal plants are effective in treating hyperlipidemia. This study examined the effects of wheat grass on high-fat diet-induced hyperlipidemia in rabbits. Thirty rabbits were divided into 3 groups of 10 rabbits each, group I receiving a control diet, group II a high-fat diet and group III a high-fat diet together with wheat grass over a period of 10 weeks. Fasting serum samples from the animals were analyzed for total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), malondialdehyde (MDA), reduced glutathione (GSH) and vitamin C, and the results were compared. The high-fat diet resulted in hyperlipidemia and an increase in oxidative stress, indicated by a significant rise in MDA levels, whereas antioxidant levels of GSH and vitamin C were significantly reduced. Wheat grass supplementation with a high-fat diet resulted in improved lipid levels (decreased total cholesterol and increased HDL-C) together with significantly reduced MDA levels and increased GSH and vitamin C levels. These results indicate the beneficial role of wheat grass in ameliorating hyperlipidemia and the associated oxidative stress.

Abstract
Ischemia modified albumin (IMA) is a proven cardiac marker but its role in type 2 diabetes mellitus without vascular complications has not been reported yet. Therefore, IMA was estimated in 60 newly diagnosed patients of type 2 diabetes mellitus and 30 healthy controls along with HbA1c and other investigations (to rule out vascular complications). There was no significant change in IMA levels in type 2 diabetic patients as compared to controls. No correlation could be found between IMA levels and HbA1c. We conclude that IMA levels are not affected in type 2 diabetes mellitus before the onset of vascular complications.

Abstract
Phototherapy has been related to increased oxidative stress and lipid peroxidation. In the present study, thirty full term jaundiced neonates with appropriate weight were analyzed before and after completion of phototherapy for malondialdehyde (MDA), reduced glutathione (GSH), total thiols, vitamin C and superoxide dismutase (SOD) levels in hemolysate and albumin levels in plasma. These parameters were analyzed in cord blood samples of 20 healthy neonates as control. It was observed that levels of MDA were elevated significantly (p<0.001) in patients as compared to controls and that the levels increased significantly after phototherapy (p<0.001). Levels of SOD were also found to be increased significantly as compared to controls and the levels rose after phototherapy (p<0.001). On the other hand, the levels of non-enzymatic antioxidants such as GSH, total thiols and vitamin C were significantly low (p<0.001) as compared to controls and the levels decreased significantly after phototherapy (p<0.001). The plasma albumin levels also were found to be decreased significantly after phototherapy (p<0.01). Therefore, phototherapy increases oxidative stress and should be used with care.
