Aim: To explore the efficacy potential of ethanolic root extract of Rauwolfia serpentina against Chromium (VI) toxicity in fish, Channa punctatus. Methodology: Acclimatized fish were divided into six groups, each having 15 specimens. Group I served as a control, while Group II and III fish were exposed to ethanolic root extract of Rauwolfia serpentina (3 mg l-1) and Cr (VI) (96 h LC50/10; 7.68 mg l-1), respectively. Groups IV, V and VI fish were exposed to three different concentrations of ethanolic root extract of Rauwolfia serpentina (1, 2 and 3 mg l-1), simultaneously with 7.68 mg l-1 of Cr (VI). The induction of micronuclei, chromosomal aberrations, protein levels and liver enzymes-SGOT, SGPT and ALP- were assessed in fish of all six groups after designated exposure periods. Results: A significant induction (p<0.05) in chromosomal aberrations, micronuclei frequency and activities of liver enzymes (SGOT, SGPT and ALP) coupled with reduced protein level was recorded in Group III as compared to the control. Whereas, a significant (p<0.05) decrease in the frequency of chromosomal aberrations, micronuclei induction and activities of liver enzymes together with an increase in protein level was observed in Group IV, V and VI with respect to control and Group III. Interpretation: Present investigation evince the ameliorative potential of ethanolic root extract of Rauwolfia serpentina against Cr (VI) induced chromosomal aberrations and micronuclei induction, changes in protein levels and biochemical alterations of liver enzymes in Channa punctatus. Thus would help present work helps in saving the aquatic biodiversity and increasing the production of protein rich food fish.

Aim: The present study was designed to evaluate the plausible efficacy of ethanolic extract of Rauwolfia serpentina to mitigate copper induced toxicity by investigating cytogenetic biomarkers, i.e., chromosome aberrations (CA) and micronucleus (MN) formation; assessment of biochemical changes in liver enzymes (SGOT, SGPT and ALP) and estimation of protein levels in a freshwater spotted snakehead fish(Channa punctatus). Methodology: The experiment was carried out in six groups, each having 15 specimens for 24, 48, 72, and 96 hr. Group I served as control. Groups II and III were maintained with 3 mg l-1 of Rauwolfia root extract and 0.4 mg l-1 of Cu2+, respectively. Groups IV, V, and VI were simultaneously co-exposed with 0.4 mg l-1 of Cu2+ and three different concentrations of Rauwolfia root extract 1, 2 and 3 mg l-1, respectively. For the genotoxicity assessment, blood and kidney tissues were used. Hepatic impairments were assessed after each exposure period. Results: A significant increase (p<0.05) in chromosomal aberrations, micronuclei frequency, activity of liver enzymes (SGOT, SGPT and ALP) and a decrease in protein level were recorded in Group III in comparison to the control. Groups co-exposed with Cu2+and Rauwolfia serpentine showed a significant (p<0.05) decrease in cytogenetic biomarkers, activity of liver enzymes and an increase in protein levels, as compared to Group III, with respect to control in a dose dependent manner. Interpretation: Thus, result of the present investigation establish the efficacy of R. serpentina root extract against Cu2+ induced toxicity in spotted snakehead (Channa punctatus).

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Male, albino rats were fed diets containing 5%, 20%, and 40% casein by weight for 7 days at environmental temperatures of 22 °C and 2–3 °C. In one experiment, food was provided ad libitum; in a second experiment, all groups were provided with equal amounts of food. At 22 °C, the activities in liver of alanine-glutamic transaminase, phosphate-activated glutaminase, and arginase increased with increasing dietary protein level. At 2–3 °C, activities of the last two enzymes increased with increasing dietary protein level from 5% to 20% but not from 20% to 40% whereas transaminase activities increased throughout the dietary protein range 5% to 40%. No relationship of glucose-6-phosphatase activity to dietary protein level was evident at either environmental temperature. Cold exposure per se increased the activities of alanine-glutamic transaminase and glucose-6-phosphatase in all dietary protein groups but increased the activities of arginase and phosphate-activated glutaminase only in rats fed the 5% and 20% protein diets. It is postulated that increased activities of these liver enzymes during cold exposure result from augmented catabolism of substrates to meet increased energy requirements. As previously observed with respect to other metabolic alterations, it is apparent that cold exposure modifies the response of liver enzymes to changing dietary protein levels.

The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and sulfasalazine in combination with herbal medicine on dextran sodium sulfate- (DSS-) induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n=9): Group I (normal group), Group II (DSS control group), Group III (DSS + sulfasalazine (30 mg/kg)), Group IV (DSS + sulfasalazine (60 mg/kg)), and Group V (DSS + sulfasalazine (30 mg/kg) + Cinnamomi Cortex and Bupleuri Radix mixture (30 mg/kg) (SCB)). Colonic pathological changes were analyzed using hematoxyline/eosin staining. The antioxidant, inflammatory, and apoptotic protein levels were determined using western blotting. SCB supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SCB treatment significantly reduced the expression of proinflammatory signaling molecules through suppression of both mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways and prevented the apoptosis of the colon. Moreover, SCB administration significantly led to the upregulation of antioxidant enzymes including SOD and catalase. Taken together, SCB treatment might offer a better treatment for human UC than sulfasalazine alone or may be useful as an alternative therapeutic strategy against UC, without any evidence of side effects.

PURPOSE: To analyse if the carbonyl proteins measurement could be validated as a method that allows the identification of an intestinal oxidative stress after ischemia and reperfusion injury. METHODS: Twenty-five male Wistar rats (n =21) weighting 200 to 250g were divided into three groups. Group I - control (n = 10). Group II - sham (n = 5) and Group III (n = 10) subjected to 60 minutes of intestinal ischemia and equal period of reperfusion. For this purpose it was clamped the superior mesenteric artery in its distal third. Histological changes and carbonyl protein levels were determined in the samples of all groups. In group III, samples of both normal and reperfused ileal segment were studied. RESULTS: All the reperfused segments showed mucosal and submucosal swelling and inflammatory infiltrate of the lamina propria. Levels of carbonyl protein rose in group III, including in the non-ischemic segments. The sensitivity and specificity of the carbonyl protein tissue levels were respectively 94% and 88%. CONCLUSION: The carbonyl protein method is a useful biologic marker of oxidative stress after the phenomenon of intestinal ischemia and reperfusion in rats. It was also noteworthy that the effects of oxidative stress could be seen far from the locus of the primary injury.

This study is about to discover the consequences of 4G mobile phone emission on MDA, anti-oxidants, antioxidant marker, and histo-pathological variations in the kidney of rats.144 male rats were separated into four groups. The Group I is considered as the control group, Group II was subjected to mobile radiation 2400 MHz frequency range for 3 hours/day for the period of 6 months, Group III was as same as Group II but treated with 250 mg/kg aqueous extract of Withania somnifera root (Aq-Wsr) orally for 6 months. Group IV was given 250 mg/kg Aq-Wsr alone for 6 months. The animals were euthanized and the kidneys cells have been evaluated for antioxidant and histo-pathological parameters. Results of the study demonstrated that the LPO were significantly raised (p < 0.05) while SOD, CAT, GSH and GPx were significantly lowered (p < 0.05) in the EMR exposed group when compared to the Group I and Group III. In histo-pathological observation, intertubular congestion, haemorrhage, necrotic changes in cortex and medulla, cast formation within the proximal and distal tubules have  elevated significantly inside the EMR group compared to the control group (p <.05). Contrarily, the total number of glomeruli in the cortex of EMR group of subjects decreased compared to the Control group (p< 0.05). The defensive effects of Aq-Wsr were witnessed within the kidney of Group III rats. From the study, it is very significant to raise open awareness of promising harmful consequences of cell phone radiofrequency EMR exposure.

Objective Obesity is a common disorder in our country. Most widely used method to gauge obesity is Body Mass Index (BMI) which is equal to weight in kilogram divided by height in meter square. The objective of our study was to find the levels of liver enzymes ALT, AST & GGT in two groups (overweight individuals and obese individuals). Methods: A total no of 156 individuals were selected for the study and they were categorized into three groups on the basis of BMI- Group I Normal, BMI 18.5 to 24.9 (n=72), Group II Overweight, BMI 25.0 to 29.9 (n=39) and Group III Obese, BMI >30 (n=45). Serum ALT, AST & GGT were estimated by Accurex AC 112 plus semi auto analyser and values were given in U/L. Results: Values of ALT, AST & GGT were with in the normal references range in all the three groups. Conclusion: No significant relation was found between ALT, AST & GGT in normal, overweight and obese individuals.
