Abstract Abamectin (avermectin B1, ABM) has been widely used as a biocide in agriculture, veterinary and medicine worldwide. In the current study, we aimed to evaluate the acute toxicity and sub-lethal biochemical responses of ABM on the non-target land snail, Theba pisana. Mortality of snails increased with the dose increase, resulting 48h- LD50 value of 1.048 µg/snail. Sub-lethal effects were studied on the survivors of 20% and 60% LD50 ABM doses and the biochemical parameters were assessed for up to 7 days of exposure. The results showed a decrease in glycogen content and lipids for two sub-lethal doses after all time intervals, whereas increased the level of total proteins after exposure to 60% LD50 ABM. Overall, the tested sub-lethal doses significantly decreased the total energy reserves. ABM-exposure to snails elevated γ-Glutamyl transferase (γ-GT) and Lactate dehydrogenase (LDH) activities at all-time intervals. A significant increase of Glutathione-S-transferase (GST) activity was also recorded in snails exposed to 20% and 60% LD50 after 7 days and all time intervals, respectively. However, ABM inhibited the activity of Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) after 7 days of exposure. Our investigation provides new insights into the disturbances of energy reserves and enzyme activities in T. pisana snails that can be used as useful sentinel organism. Indeed, these tested biochemical parameters of the snails are sensitive and may be used as biomarkers for assessing ABM toxicity.

Toxigenic Strain

Aflatoxin produced by Aspergillus flavus toxigenic strain was selected as a potent and widely distributed hepatotoxin that induces much health and economic hazards in animals and humans. A. flavus was cultivated on rice to produce the aflatoxin used in the present study. It was aimed to study the adverse effects of aflatoxin on some biochemical parameters in serum and liver of ducklings as well as to evaluate the possible protective effects of N.sativa crushed seeds against the adverse effects of this. Total proteins, albumin, globulins, alanine aminotransferase (ALT) (EC 2.6.1.1) and aspartate aminotransferase (AST) (EC 2.6.1.2), cholesterol and triacylglycerols were measured in the serum of the test animal. The levels of hepatic malondialdhyde and glutathione level, glutathione S-transferase (GST) (EC: 2.5.1.18) activity, aflatoxin residues and histopathological changes were also measured. The obtained results suggest that the addition of N. sativa to duckling’s ration has a protective effect against aflatoxicosis. The result concluded that aflatoxin had hepatotoxic effects through decrease of total proteins, albumin, glutathione and glutathione S-transferase. In addition, aflatoxin induced histopathological changes of liver of the test animal and residues of aflatoxin were measured. So, we advice to use N. sativa as a feed additive for controlling aflatoxicosis in poultry farm   DOI: http://dx.doi.org/10.3126/njst.v14i2.10419   Nepal Journal of Science and Technology Vol. 14, No. 2 (2013) 81-90

Black Seed

This feeding trial was conducted to investigate the effects of dietary black seed (Nigella sativa) supplementation on the growth performance, muscles proximate composition, antioxidant and histo-biochemical parameters of rohu (Labeo rohita). Fingerlings (8.503 ± 0.009 g) were fed on 0.0%, 1% and 2.5% black seed supplemented diets for 28 days. Fish sampling was done on the 7th, 14th, 21st and 28th day of experiment. The results of the present study indicated that black seed supplementation significantly increased growth performance and muscles protein contents of rohu over un-supplemented ones. Lipid peroxidation levels significantly decreased in all the studied tissues (liver, gills, kidney and brain) of black seed fed rohu, whereas the antioxidant enzymes (catalase, glutathione-S-transferase, glutathione peroxidase and reduced glutathione) activities were increased in all the studied tissues of black seed supplemented rohu at each sampling day. The hepatic-nephric marker enzymes levels were decreased for black seed fed rohu. The present study showed that tested black seed levels are safe for rohu. Black seed is cheaply available in local markets of Pakistan; therefore, based on the results of the present study, it is suggested that black seed has potential to be used as natural growth promoter and antioxidant in the diet of rohu.

1 Biochemical markers of kidney damage were examined in 16 female workers chronically exposed to tetrachlorethylene (TCE) in five dry-cleaning shops. The results were compared with those obtained in 13 females non-occupationally exposed to organic solvents. 2 The intensity of exposure was monitored by personal environmental monitoring. The time-weighed average exposure to TCE amounted to 157 mg m-3 (range 9-799 mg m-3). A satisfactory agreement was found between the concentration of TCE in ambient air sampled with the charcoal tube method and with a passive dosimeter. 3 The urinary excretion of lysozyme was increased in the exposed group. No difference was found in the urinary excretion of albumin, β2-microglobulin, lactate dehydrogenase, total proteins or glucose. The prevalence of abnormal values of biochemical parameters in the exposed group did not differ from that observed in the control group. No correlation was found between the level of TCE exposure and biochemical parameters. 4 The present study suggests that chronic exposure to TCE does not lead to renal damage.

Reference interval (RIs) were critical to the identification of illness. However, RIs set in one laboratory may not be appropriate for another because of biological, geographical and instrumental factors. Interpretation of clinical data using inappropriate RIs may cause misclassification of results and misdiagnosis that lead to improper treatment. RIs in Taiwan have been mostly referencing from foreign resources, it is desirable to establish one that is closer to the overall conditions in Taiwan (such as breed, climate, diseases, etc.) and to investigate its differences to foreign RIs. The present study used the American Society for Veterinary Clinical Pathology (ASVCP) guidelines to establish in-house RIs for hematological, biochemical and coagulation parameters using dogs in middle Taiwan. The results were also compared to two foreign and one local RIs. The results suggested that the hematological RIs are more comparable to foreign RIs than the biochemical and hemostatic parameters. Differences were found for biochemical parameters including gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), lipase, uric acid, bile acid, bilirubin and magnesium; and coagulation parameters including prothrombin time (PT) and activated partial thromboplastin. In all, 18% (7/40) of the all tested parameters were different from the local RI while 38% (18/48) and 41% (19/46) of the parameters were different from the two foreign RIs. The differences in more than 30% RIs and better similarities to local RIs underscore the importance of having own RIs if possible.

Hypometabolic State

During arousal from estivation oxygen consumption by land snails (Otala lactea) increases severalfold. To determine whether snails prepared for an accompanying rise in the rates of oxyradical generation by altering their antioxidant defense mechanisms, changes in the activities of antioxidant enzymes and lipid peroxidation products were quantified in foot and hepatopancreas of control, 30-day estivating, and aroused snails. Compared with controls, estivating O. lactea showed significant increases in the activities of foot muscle superoxide dismutase (SOD) (increasing by 56-67%), catalase (51-72%), and glutathione S-transferase (79-108%), whereas, in hepatopancreas, SOD (57-78%) and glutathione peroxidase (93-144%) increased. Within 40 min after arousal began, hepatopancreas glutathione peroxidase activity had returned to control values, but SOD showed a further 70% increase in activity but then returned to control levels by 80 min. Estivation had no effect on total glutathione (GSH + 2 GSSG) concentrations in tissues, but GSSG content had increased about twofold in both organs of 30-day dormant snails. Lipid peoxidation (quantified as thiobarbituric acid reactive substances) was significantly enhanced at the onset of arousal from dormancy, indicating that oxidative stress and tissue damage occurred at this time. The data suggest that antioxidant defenses in snail organs are increased while snails are in the hypometabolic state as a preparation for oxidative stress during arousal.

Rudgea viburnoides leaves are widely used in popular Brazilian medicine as a diuretic, antirheumatic, hypotensive and blood depurative tea. The present study was carried out to investigate the effects of this infusion on the liver and on the plasma biochemical parameters of Wistar rats. Two groups received the R. viburnoides leaf infusion at a daily dose of 10 or 20g dry-leaves/L water, during 40 days. The histopathological analysis did not show degenerated areas or infiltration of leucocytes. Hepatic morphometry showed accumulation of fat in the hepatocytes of the treated groups. There was no significant change in the plasma levels of urea, creatinin, uric acid, direct bilirubin, cholesterol, total proteins, albumin, gamma glutamyl tranferase (gamma-GT), alanine transaminase (ALT), aspartate transaminase (AST), chlorine, phosphate and calcium. A significant reduction in the plasma levels of triacylglycerol (TAG) occurred in the group that received the higher dose.

AbstractAt two natural volcanic seeps in Papua New Guinea, the partial pressure of carbon dioxide (pCO2) in the seawater is consistent with projections for 2100. Here, the cover of massive scleractinian corals Porites spp. is twice as high at elevated compared with ambient pCO2, while that of branching corals such as Acropora millepora is greater than twofold reduced. To assess the underlying mechanisms for such community shifts under long-term exposure to elevated pCO2, biochemical parameters related to tissue biomass, energy storage, pigmentation, cell protection, and cell damage were compared between Porites spp. and A. millepora from control (mean pHtotal = 8.1, pCO2 = 323 µatm) and CO2 seep sites (mean pHtotal = 7.8, pCO2 = 803 µatm) each at two reefs. In Porites spp., only one of the biochemical parameters investigated (the ratio of photoprotective to light-harvesting pigments) responded to pCO2, while tissue biomass, total lipids, total proteins, and some pigments differed between the two reefs, possibly reflecting differences in food availability. Furthermore, some fatty acids showed pCO2 –reef interactions. In A. millepora, most pigments investigated were reduced at elevated pCO2, while other parameters (e.g. tissue biomass, total proteins, total lipids, protein carbonyls, some fatty acids and pigments) differed between reefs or showed pCO2–reef interactions. Tissue biomass, total lipids, and cell-protective capacities were distinctly higher in Porites spp. than in A. millepora, indicating higher resistance to environmental stress in massive Porites. However, our data suggest that important biochemical measures remain relatively unaffected in these two coral species in response to elevated pCO2 up to 800 µatm, with most responses being smaller than differences between species and locations, and also when compared with responses to other environmental stressors such as ocean warming.

Changes in physiological and biochemical parameters after administration of medetomidine (MED), midazolam (MID), ketamine (KET) and a 2% of the inhalation anesthetic sevoflurane (SEVO), were investigated in domestic chickens. The anesthetic protocol began with a simultaneous intrapectoral injection (IP) of MED (50 μg/kg) and MID (0.5 mg/kg), followed by IP administration of 25 mg/kg of KET 10 min later. Anesthesia was then maintained for 30 min by 2% SEVO (with a 500 ml/min oxygen flow), using an Ayres T piece device. Heart and respiratory rates, cloacal temperature, reflex response and electrocardiogram (ECG) parameters were recorded at time cero (T0) before anesthesia (BA, baseline values), at time of MED+MID administration (T1), at time of ketamine injection (T2), 30 min after the start of SEVO inhalation (T3) and at recovery. Blood was also drawn at T0 and T3 to assess albumin, creatinine, glucose and liver enzyme concentrations. Cloacal temperature, heart and respiratory rates differed from baseline values at all time intervals during anesthesia (p<0.05). Heart rate decreased following the MED + MID injection (at T1, T2 and T3), and partially recovered by the reanimation period. Reflex response also differed between time 0 and all anesthesia time points (p<0.05). Mean amplitude of the P wave of the ECG was increased during MED + MID (T1) and KET (T2) anesthesia. The mean ST interval showed a large increase at T1, which was maintained throughout anesthesia (p <0.05). Albumin, glucose and the ALT enzyme decreased between T0 and T3. In conclusion, the use of MED+MID+KET and SEVO as an anesthetic combination altered cardiorespiratory and biochemical parameters of chickens, but no life-threatening effects were observed as a result of these changes. Hence, this drug combination can be adequately used as an anesthesia protocol in chickens.
