ABSTRACT
Background: The pathophysiology of Type 2 Diabetes Mellitus (T2DM) is characterized by deficient insulin activity arising from decreased insulin secretion secondary to beta cell failure, and/or compromised insulin action in peripheral target tissues (insulin resistance).Methods: The patients attending the medicine outpatient department of tertiary care teaching hospital were enrolled in the study. Patients, who fulfilled the selection criteria, were allocated in two treatment groups. Group A was treated with metformin (Sustained release preparation) 500mg once daily and group B was treated with vildagliptin 50mg once daily. Measurement of body weight, fasting blood glucose (FPG), postprandial blood glucose (PPG), glycated haemoglobin (HbA1c), serum urea, creatinine and urine albumin/creatinine ratio was performed at the initial visit and at the end of 12 weeks of treatment.Results: Out of 84 patients screened, 74 were enrolled for the study. Of the 74 patients, 39(52.7%) were male and 35(47.3%) were female. The patients were divided into two groups (group A and group B) consisting 37 patients in each group. Out of 74 patients, 62 completed the study. Out of 12 patients who did not complete the study, 5 patients were lost during follow-up period and 7 patients discontinued treatment due to AEs. The mean age of the patients was 51 and 49years in the groups A and B respectively. There was no statistical difference in the baseline FPG, PPG, HbA1c, serum urea, serum creatinine, urine ACR and body weight between two groups.Conclusions: The study shows that metformin and vildagliptin have similar effect on glycaemic control, but vildagliptin exerts better Reno protective effect and there were no reports of serious adverse events.
ABSTRACT
Objective To observe the effects of Soyasaponins on inflammatory factors, antioxidant activity and exercise ability in rats with severe heat stroke. Methods Eighty male Sprague-Dawley (SD) rats were randomly divided into normal control group, heat shock model group, saline control group and Soyasaponin group, The rats that died during the experiment or with a low rectal temperature (< 41℃) were excluded, and finally 54 rats were included, 18 rats remaining in each group. The rats in the heat shock model group were placed in the simulated hot climate animal cabin at 30 ℃, and the temperature within 30 minutes was raised to 39 ℃ in the cabin with 65% humidity; in the mean time, the rat models of heat shock were replicated under the following situations: let the rats exercise on a treadmill with running speed set at 15 m/min, slope degree 0°, once running for 8 minutes, interval 2 minutes and the heat shock time was 90 minutes, the rats in the normal control group were fed in an environment with temperature ranging from 23-25 ℃ and relative humidity ranging from 50%-70%. After the establishment of models, the saline control group and Soyasaponin group were given daily saline and Soyasaponin (10 mg/kg) respectively by gavage for 3 consecutive months, while the heat shock model group was not given any treatment. The femoral artery blood was collected 24 hours after the rats left the cabin. The serum levels of interleukins (IL-6, IL-1β), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), malonaldehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) were measured by enzyme-linked immunosorbent (ELISA) and the contents of serum hemoglobin (Hb), serum urea (BUN), lactate dehydrogenase (LDH) and blood lactic acid (Lac) were measured by automatie biochemical analyzer. Results The levels of IL-6, IL-1β, TNF-α, IFN-γ, MDA, Hb, BUN, LDH, Lac in heat shock model group were significantly higher than those of the normal control group [IL-6 (ng/L): 86.17±4.82 vs. 12.60±3.49, IL-1β (ng/L): 83.00±5.98 vs. 15.70±3.64, TNF-α (ng/L): 72.22±6.93 vs. 13.75±2.69, IFN-γ (ng/L): 36.22±3.02 vs. 7.35±1.60, MDA (nmol/mg): 19.78±4.56 vs. 6.40±1.35, Hb (g/L): 136.22±1.93 vs. 126.75±5.84, BUN (mmol/L):21.06±3.44 vs. 5.65±1.35, LDH (μmoL·s-1·L-1): 9.65±0.83 vs. 2.12±0.17, Lac (mmol/L): 552.56±78.33 vs. 1.32±0.18, all P ＜ 0.05], SOD and GSH-Px were significantly lower than those in normal control group [SOD (kU/L):97.89±10.57 vs. 126.65±11.35, GSH-Px (kU/L): 19.22±2.58 vs. 43.45±4.02]; however, the levels of IL-6, IL-1β, TNF-α, IFN-γ, MDA, BUN, LDH and Lac in Soyasaponin group were significantly lower than those in heat shock model group [IL-6 (ng/L): 45.28±3.54 vs. 86.17±4.82, IL-1β (ng/L): 41.61±2.93 vs. 83.00±5.98, TNF-α (ng/L):37.22±2.46 vs. 72.22±6.93, IFN-γ (ng/L): 19.22±2.60 vs. 36.22±3.02, MDA (nmol/mg): 11.28±1.74 vs. 19.78±4.56, BUN (mmol/L): 11.78±2.13 vs. 21.06±3.44, LDH (μmoL·s-1·L-1): 3.70±0.26 vs. 9.65±0.83, Lac (mmol/L): 274.56±59.08 vs. 552.56±78.33, all P < 0.01], SOD, GSH-Px and Hb were significantly higher than those of heat shock model group [SOD (kU/L): 116.11±11.28 vs. 97.89±10.57, GSH-Px (kU/L): 31.17±2.90 vs. 19.22±2.58, Hb (g/L): 141.33±3.79 vs. 136.22±1.93, all P < 0.01]; there were no significant statistical differences in above indexes between heat shock model group and saline control group (all P > 0.05). Conclusion After heat shock and exercise management, the production and release of inflammatory factors are increased, and the level of lipid peroxidation was elevated in rats. The Soyasaponin can improve the ability to withstand heat shock and strong exercise by reducing the production and release of inflammatory factors and lipid peroxidation in the rats with severe heatstroke.
ABSTRACT
Background: Smoking harms nearly every organ of the body and diminishes a person’s overall health. Millions and millions of peoples have health problems due to the habit of smoking. It is now a burden worldwide because smoking addiction of teenagers increasing immensely. Globally, smoking is not only a leading cause of cancer as well as various heart diseases. Smoke contains several carcinogenic pyrolytic products like Polycyclic Aroma0tic Hydrocarbons (PCAH), acrolein etc. are irreversible binds to DNA, causes genetic mutation and cancer. Aim: To evaluate the effect of smoking on Blood biochemistry parameters. Materials and methods: Totally 68 subjects were included in the study. 34 current smokers who came from in and around Chidambaram to the RMMC and Hospital who fulfilled the inclusion criteria were selected as an experimental group. Another 34 non-smokers of the same age group were included separately in this study as a control group. So a total of 68 respondents were contacted for the study. The primary data were collected during the 2016-2017 period of around one year. biochemical parameters such as blood glucose, blood urea, and lipid profile were analyzed using standard methods. Results: While comparing the mean Blood sugar, Serum Cholesterol, Triglycerides, HDL, and LDL values, it was found to be more in smokers compared to that of non-smokers and this was significant at 5% level for Blood sugar and at 1% level for other values like cholesterol, TGL, HDL, and LDL. The mean Blood urea value had no significant association with smoking. Conclusion: Subchronic and acute exposure to tobacco smoke and various tobacco smoke constituents have been shown to elicit a wide variety of cardiovascular effects in animal models. These effects include decreased oxygen-carrying capacity, resulting in ischemia, platelet activation, endothelial damage, altered lipoprotein levels and increased arterial wall thickness which can promote atherosclerosis, and thrombosis. Ischaemia, atherosclerosis, and thrombosis increase the risk of myocardial infarction and other serious cardiovascular effects.

ABSTRACT
The liver and kidney are very important organs of the body that play vital roles of detoxification of compounds and removal of waste products respectively. In this research, some liver and kidney function tests were carried out on albino mice infected with malaria parasite to know the effect of treatment with extract on them. Pulverised dried seeds of Picralima nitida were extracted using ethanol. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities, total bilirubin, total protein, urea and creatinine levels and histopathological studies on liver and kidney tissues were performed. From the results of the experiment, significant (p < 0.05) reductions were observed in serum levels of urea, creatinine of the treated groups compared to the positive control (group infected with malaria parasite and treated with 3% tween 80) on days 3 and 5 post treatment. There was non-significant (p > 0.05) reduction in serum AST and ALT activities of the groups treated with 20, 40 and 80 mg/kg b.w. of the extract on days 3 and 5 post treatment compared to the positive control. Groups treated with 20 and 40 mg/kg b.w. of the extract showed significant (p < 0.05) reduction in bilirubin level on days 3 and 5 post treatment compared to the positive control. All the treated groups showed significant (p < 0.05) elevation in serum total protein on day 3 post treatment while the group treated with 80 mg/kg b.w. of the extract showed significant (p < 0.05) elevation in total protein on day 5 treatment compared to the positive control. Histopathological studies on the hepatic tissues of the treated mice showed lesser inflammatory cells around the portal areas than the untreated. No lesions were noticed in the renal tubules of both the treated and untreated mice. From the results of this experiment, it is now obvious that Picralima nitida seeds possess good hepato-protective properties.
ABSTRACT
Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.
ABSTRACT
Portulaca oleracea L. has been used as a food and medicinal plant for thousands of years in China. Polysaccharides extracted from P. oleracea L. (POP) are its main bioactive compound and have multiple pharmacological activities. However, anti-fatigue effects of POP have not yet been tested. This study was designed to investigate the anti-fatigue effects of POP in mice using the rotarod and forced swimming tests. The mice were randomly divided into four groups, namely normal control group, low-dose POP supplementation group, medium-dose POP supplementation group and high-dose POP supplementation group. The normal control group received distilled water and the supplementation groups received different doses of POP (75, 150 and 300 mg/kg, respectively). The POP or distilled water was administered orally and daily for 30 day. After 30 days, the rotarod and forced swimming tests were performed and then several biochemical parameters related to fatigue were determined. The data showed that POP prolonged the riding times and exhaustive swimming times of mice, decreasing blood lactic acid and serum urea nitrogen levels, as well as increasing the liver and muscle glycogen contents. These results indicated that POP had the anti-fatigue effects.

Background: Hypertensive disorders of human pregnancy, such as preeclampsia, complicate a sizeable percentage of all pregnancies, needing its early indication and warning. Aims & Objective: To measure and compare serum uric acid, serum creatinine and serum urea in pre-eclamptic and normotensive groups. Material and Methods: This is a cross-sectional, hospital based study involving 105 age – matched women of South India (devoid of diabetes, urinary tract infections, renal or liver disorders), all in their third trimester singleton pregnancy, at the Obstetrics and Gynaecology Department of Sri Ramachandra Medical College and Hospital, Chennai, India during the period of December 2008 to July 2009. The data were collected following standard procedures and statistical analysis was done using unpaired t – test. Results: The levels of serum uric acid and serum creatinine, expressed in mg/ dL were significantly elevated in pre-eclamptics respectively (5.29 ± 0.84 and 0.72 ± 0.387) when compared to normotensives (3.86 ± 0.92 and 0.58 ± 0.283). There was a statistically insignificant and small increase in serum urea level in pre-eclamptics (28.07 ± 4.97) compared to normotensives (26.46 ± 3.55). There was a lack of any correlation between the positive differences in the values of each parameter with the extent of corresponding raised blood pressure. Conclusion: The elevated values of uncorrelated serum uric acid, serum creatinine or serum urea thus precludes them to be useful for consideration as consistent predictive indicator(s) for preeclampsia or pregnancy related h
ABSTRACT
Purpose: To evaluate the effect of vitamin B-complex on the nephrotoxicity of gentamicin in an established rat model. Methods: Adult Swiss albino rats weighing 170±20g were divided into 4 groups of 4 rats each. Each group was given one of the following: placebo injection (Control), 80mg/kg of gentamicin sulphate alone or with 1.5ml/kg/3ml/kg body weight of vitamin B-complex (intramuscular) containing 10mg thiamine, 1.5mg riboflavin and 1.0mg pyridoxal-6-phosphate per ml. Results: In the Swiss albino rats, daily intramuscular 80mg/kg gentamicin sulphate significantly (p<0.05) and consistently produced biochemical signs of nephrotoxicity after 5 days. Also, 1.5 ml/kg of B-complex significantly (p<0.05) ameliorated the rate and extent of increase in serum urea and creatine while 3ml/kg of the same drug completely prevented the increase in serum urea and creatine in this model. Conclusion: Vitamin B-complex dose-dependently ameliorated gentamicin-induced nephrotoxicity in adult Swiss albino rats when given intramuscularly. This finding may have important clinical utility

ABSTRACT
The prevalence of low serum urea nitrogen concentrations (<6 mg/dL) in our patient population was 3.8% (452 per 11,911 determinations), representing 372 individual cases. Of these, 323 of the patients' charts were located, reviewed, and classified into disease groups. Malignant tumor was found in 25.1% of the 323 patients, the remaining patients without malignant tumor had various clinical conditions; pregnancy (19.5%), infectious diseases (12.1%), trauma (10.2%), cerebrovascular accident (6.2%), hepatopathy (5.3%), and miscellaneous conditions (21.6%). The prevalence in female and young aged patients under 5 years was considered due to the lower reference range in these groups than in that of female adult groups, and moreover pregnancy in another superimposing factor in the former group. In regards to the causes of this condition, our study corresponded well to the textbook cited etiology of the low serum nitrogen concentration, although malnutrition and hepatopathy were inverted in their incidental order. We postulated, through the present study, that the low serum urea nitrogen concentration is not pathognomonic findings to suggest specific disease or conditions, but rather to reflect patient's general conditions such as hydration, nutrition, or administration of certain drugs.
