TL;DR: Higher mean corpuscular haemoglobin concentration (MCHC), blood glucose and lactate dehydrogenase (LDH) levels in T5 group revealed that higher concentration of azadirachtin have notable effects on activity of vital tissues function and physiology of the host.
Abstract: Argulosis hampers aquaculture production and alters the host physiology and growth. Azadirachtin is recognized as a potential antiparasitic agent against Argulus sp. The present study aimed to investigate the effect of different concentration of azadirachtin solution on haematological and serum biochemical parameters of Argulus-infested goldfish Carassius auratus. Ninety Argulus-infested goldfish were randomly divided into six equal groups. Fish of group 1-5 were treated with azadirachtin solution through bath of 1, 5, 10, 15 and 20 mg L(-1) as T1, T2, T3, T4 and T5, respectively, and group 6 was exposed to 2% DMSO solution without azadirachtin and considered as negative control T0(-). Along with six treatment groups, a positive control T0(+) of healthy goldfish free from Argulus infestation was also maintained. Parasitic mortality was evaluated after 3 days of consecutive bath treatment. After 7 days of post-treatment, the blood and serum were drawn from each of the treatment groups and haematological and serum biochemical parameters were evaluated. Total leucocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood glucose, total protein (TP), globulin, serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were significantly (p < 0.05) high in negative control group when compared with positive control group. It could be concluded that Argulus infestation altered marked haematological and serum biochemical parameters. However, in treated groups complete elimination of Argulus was found in T4 and T5 groups. Also significant (p < 0.05) reduction in haematological and serum biochemical parameters of all the treatment groups were recorded in comparison with negative control group. In addition, T4 and T5 groups showed significantly (p < 0.05) high superoxide dismutase (SOD), catalase, total erythrocyte count (TEC) and haemoglobin (Hb). However, higher mean corpuscular haemoglobin concentration (MCHC), blood glucose and lactate dehydrogenase (LDH) levels in T5 group revealed that higher concentration of azadirachtin have notable effects on activity of vital tissues function and physiology of the host. Argulus spp. from infested goldfish could be eliminated using bath treatment with solution of azadirachtin having concentration of 15 mg L(-1) and that also shifted haematological and serum biochemical parameters towards homeostasis.

TL;DR: It was concluded that the hepatoprotective effects of the three plant extracts observed in this study might result from their potent antioxidative properties.
Abstract: Introduction Roots of Ixora coccinea (Rubiaceae), and Rhinacanthus nasuta (Acanthaceae) and whole plants of Spilanthes ciliata (Asteraceae) are extensively used by tribal communities in South India to treat liver diseases. However, the veracity of these tribal claims has not been investigated scientifically using the liver toxin, aflatoxin. This study reports on the protective effects of these three herbal ethanolic extracts on the aflatoxin B1 (AFB1)-intoxicated livers of albino male Wistar rats. Methods Biochemical parameters, including serum hepatic enzymes (glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and alkaline phosphatase), were studied. Hepatic tissues were processed for assay of reduced glutathione (GSH) and histological alterations. Results Pre-treatment of the rats with oral administration of the plant ethanolic extracts, Ixora coccinea (IC), Rhinacanthus nasuta (RN), Spilanthes ciliata (SC), prior to AFB1 was found to provide significant protection against toxin-induced liver damage, determined 72 hours after the AFB1 challenge (1.5 mg/kg, intraperitoneally) as evidenced by a significant lowering of the activity of the serum enzymes and enhanced hepatic reduced GSH status. Pathological examination of the liver tissues supported the biochemical findings. The three plant extracts, IC, RN and SC, showed significant antilipid peroxidant effects in vitro. Conclusion It was concluded that the hepatoprotective effects of the three plant extracts observed in this study might result from their potent antioxidative properties.

TL;DR: Aqueous extracts of the seeds of Nigella sativa and mature leaves of Dregea volubilis were administered orally under light ether anaesthesia to male Sprague-Dawley rats for 14 days and key hepatic enzyme concentrations and histopathological changes in the liver at the end of 14 days were compared with a control group which received distilled water under identical conditions for 30 days.

TL;DR: The antioxidant activities of H2 blockers have an analgesic activity and protective effect on CCl4‐induced hepatotoxicity in mice and these effects were greater with ranitidine than with the other compounds.
Abstract: The antioxidant, antinociceptive and hepatoprotective effects of H(2) receptor blockers were examined with different experimental models. Antioxidant activities were determined by employing various in vitro assay systems such as 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical-scavenging activity assays, reducing power determination assays, nitric oxide-scavenging activity assays and hydrogen peroxide-scavenging activity assays. Antinociceptive effects were determined using the hot plate test in mice. The hepatoprotective effects of cimetidine, ranitidine and famotidine against hepatotoxicity induced by carbon tetrachloride (CCl(4) ) were determined by measuring the levels of serum enzymes alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) activities in mice. We found that the IC(50) values of cimetidine, ranitidine and famotidine on DPPH radical-scavenging activity were 671±28, 538±21 and 955±43 μg/mL, respectively. Famotidine showed very strong nitric oxide-scavenging activity. All three compounds showed very weak hydrogen peroxide-scavenging activity. Moreover, the compounds did not exhibit any reducing power activity until concentrations of 1.6 mg/mL. All compounds also showed a dose-dependent and marked analgesic activity in mice relative to controls. Pretreatment of mice with cimetidine, ranitidine or famotidine for three consecutive days reduced CCl(4)-induced hepatotoxicity in mice. Treatment with 200 mg/kg ranitidine reduced AST, AST and ALP serum levels, while 200 and 40 mg/kg of cimetidine and famotidine, respectively, reduced AST and ALP serum levels. H(2) blockers exhibited varying levels of antioxidant activities in various assays. Our results indicate that the antioxidant activities of H(2) blockers have an analgesic activity and protective effect on CCl(4)-induced hepatotoxicity in mice. These effects were greater with ranitidine than with the other compounds.
