Hematological and serum biochemical analyses are routinely used to screen dogs for disease and monitor their clinical progression. These values in dogs may be affected by internal factors, such as breed and age, and external factors like environment, diet, and lifestyle. Apparently, subclinical breed-related variations in hematologic and serum biochemical results have been characterized for Bernese Mountain dogs, Alaskan Malamutes, English Setters, and Golden Retrievers. It is possible that some breed-related differences in clinical pathology analyses may reflect evidence of underlying disease and impact clinical decision plan. In this study, we estimated hematologic and serum biochemical parameters in small breed dogs and compared among four different breed dogs. Blood samples were collected from 38 domestic dogs that were 10 Beagles, 9 Malteses, 10 Poodles, and 9 Miniature Schnauzers. In terms of RBC count, Beagle ($7.2{\pm}0.24{\times}10^3cells/{\mu}L$) showed significantly (P<0.05) higher count than other breeds (Maltese, $6.51{\pm}0.25{\times}10^3cells/{\mu}L$; Poodle, $6.35{\pm}0.24{\times}10^3cells/{\mu}L$; and Miniature Schnauzer, $6.35{\pm}0.25{\times}10^3cells/{\mu}L$). For MCV, Miniature Schnauzer ($67.05{\pm}0.84fl$) results were significantly (P<0.05) higher than Beagle with $64.33{\pm}0.8fl$. For cholesterol value, Beagle ($163.3{\pm}9.15mg/dl$) had significantly (P<0.05) higher values than Miniature Schnauzer with $119.12{\pm}9.64mg/dl$. There was no statistically difference among breeds in terms of enzyme markers of liver diseases. In conclusion, data obtained from this study may be valuable as breed-related variability for interpretation of the results in hematologic and serum biochemical analysis among four small breed dogs.

Inflammaging in male reproductive organs covers a wide variety of problems, including sexual dysfunction and infertility. In this study, the beneficial effects of cordycepin (COR), isolated from potential medicinal fungi Cordyceps militaris, in aging-associated testicular inflammation and serum biochemical changes in naturally aged rats were investigated. Male Sprague Dawley rats were divided into young control (YC), aged control (AC), and COR (5, 10, and 20 mg/kg) treated aged rat groups. Aging-associated serum biochemical changes and inflammatory parameters were analyzed by biochemical assay kits, Western blotting, and real-time RT-PCR. Results showed a significant (p < 0.05) alteration in the total blood cell count, lipid metabolism, and liver functional parameters in AC group when compared with YC group. However, COR-treated aged rats ameliorated the altered biochemical parameters significantly (p < 0.05 and p < 0.01 at 5, 10, and 20 mg/kg, respectively). Furthermore, the increase in the expression of inflammatory mediators (COX-2, interleukin (IL)-6, IL-1β, and tissue necrosis factor-alpha) in aged rat testis was significant (p < 0.05) when compared with YC group. Treatment with COR at 20 mg/kg to aged rats attenuated the increased expression of inflammatory mediators significantly (p < 0.05). Mechanistic studies revealed that the potential attenuating effects exhibited by COR in aged rats was mediated by regulation of NF-κB activation and MAPKs (c-Jun N-terminal kinase, extracellular signal-regulated kinase 1/2, and p38) signaling. In conclusion, COR restored the altered serum biochemical parameters in aged rats and ameliorated the aging-associated testicular inflammation proving the therapeutic benefits of COR targeting inflammaging-associated male sexual dysfunctions.

The present study was carried out to find the possible protective effects of Angelica koreana water extract on biochemical parameters in benzo(a)pyrene (B(a)P)-induced liver injury in rats. B(a)P treatment (0.1 mg/kg, 1.p.) caused a liver damages, which led to biochemical alterations in serum and liver enzyme activities and serum lipid levels. The activities of liver marker enzymes, especially, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were markedly changed in B(a)P treatment. Oral administration of Angelica koreana (50 mg/kg) recovered these biochemical Parameters to near normal levels. Therefore, the present results have revealed that Angelica koreana water extract might have the antihepatotoxic effect and consequently ameliorate liver damage associated with B(a)P in rats.

This study evaluated the hazard caused by $NO_{2}$, an oxidant generated in the process of welding. We com­pared hematological and biochemical parameters in workers who chronically inhale $NO_{2}$ and office workers not exposed to $NO_{2}$. $NO_{2}$ exposure affected the hematological and biochemical parameters. Increasing $NO_{2}$ concen­trationincreased the number of leukocytes, while decreasing the number of erythrocytes. Blood urea nitrogen, cre­atinine, uric acid, and lactate dehydrogenase were increased, while total protein and triglycerides were decreased. The mean concentration of $NO_{x}(NO_{2}^{-}/NO_{3}^{-})$ in the serum of welders and the control group was $35.97{\pm}2.85\;and\;55.40{\pm}5.81\;{\mu}mol/L,$ respectively. The difference was significant (p < 0.05), although $NO_{2}^{-}$ was not detected in the serum.

A blood biochemical analysis was carried out for the serum of wintering sea bream (red sea bream Pagrus major, black sea bream Acanthopagrus schlegeli, rock bream Oplegenathus fasciantuas) with green liver syndrome. GOT and GPT were significantaly elavated in the diseased sea bream. The value of $NH_{3}$ was slightly higher but those of TBIL. TP and UA were lower than the control. But there were no differences in albumin. Ca and glucose between the diseased and the control. These results suggent that a green liver syndrome in the sea bream might be related with nutritional defects and the stress of low water temperature during the winter.

Chlorpyrifos (CPF) is one of the most heavily used organophosphate pesticides and is useful as an insecticide drug. However, CPF also causes toxic effects in nontarget organisms, including humans and animals. Jageum-Jung (JGJ) is a traditional oriental medicine, composed of five specific herbs with antioxidant and hepatoprotective properties, used for detoxification. In the present study, highly concentrated CPF was orally administrated to male Institute of Cancer Research mice to produce acute toxicity, and the protective effects of JGJ administration were investigated through statistical analysis of changes in body and organ weights and serum biochemical parameters. JGJ caused body and organ weights to recover and reduced the levels of serum biochemical parameters indicative of liver damage, such as glutamic oxalate transaminase, glutamic pyruvate transaminase, alkaline phosphatase, lactic dehydrogenase, urea, glucose, total cholesterol, and triglyceride, that had been increased by CPF treatment. Our results demonstrated that JGJ ameliorates the effects of acute chlorpyrifos-induced toxicity. Therefore, JGJ has the potential to be used as a traditional medicine to alleviate insecticide toxicity.

A comprehensive study was undertaken to evaluate the effect of naked neck (Na) gene on immune competence, serum biochemical parameters and carcass quality traits in three genotypes (NaNa, Nana and nana) of the naked neck chicken under a tropical climate (Southern India). Sixty day-old chicks (20 from each genotype) were selected randomly and reared under similar environmental conditions up to eight weeks of age. The cell mediated immune (CMI) response to phytohaemoagglutinin-P (PHA-P) was significantly higher ($p{\lgq}0.01$) in NaNa and Nana genotypes compared to nana birds. The humoral response as measured by antibody titre to sheep red blood cells (SRBC) was also significantly higher in NaNa. The total cholesterol, LDL and VLDL cholesterol levels were significantly ($p{\leq}0.01$) lower whereas HDL cholesterol level was significantly higher in NaNa and Nana compared to nana genotype. The presence of Na allele significantly increased the live weight and dressing yield, and decreased the feather cover and abdominal fat. The naked neck genotypes (NaNa/Nana) performed better than the normal (nana) siblings for almost all the traits studied.

Objective:Nitric oxide(NO) has been known to be associated with tolerance and preference to alcohol. It has also been known to affect various alcohol drinking behavior, alcohol withdrawal symptoms and alcohol- induced brain damage. The purpose of this study was to determine the difference, among alcohol dependence group, alcohol drinking group and abstinence group, in serum concentration of nitrite, a stable metabolite of NO, and it's relationship to clinical and biochemical markers of alcoholism. Methods:Forty subjects diagnosed as alcohol dependence according to DSM-IV diagnostic criteria were evaluated for the clinical characteristics and biochemical markers of alcohol dependence including nitrite with their CIWA-Ar scores checked just after admission. Thirty-nine healthy controls were also evaluated, divided into twenty-three alcohol drinking group and sixteen abstinence group. Clinical characteristics were evaluated by CIWA-Ar, CAGE and AUDIT questionnaires. Aspartate aminotransferase(AST), alanine aminotransferase (ALT), gamma glutamyltransferase(GGT) and mean corpuscular volume(MCV) were used as the biochemical markers of alcohol dependence. Serum nitrite concentrations were measured by Griess reaction. Results:1) The concentrations of nitrite in alcohol dependence patients were not different from those in the control subjects. 2) There were no significant association between the nitrite concentrations and the CIWA-Ar scores in alcohol dependence patients. 3) Nitrites are significantly increased in alcohol dependence group and alcohol drinking group compared with abstinence group. Conclusions:These findings suggest that serum nitrite concentration has no relation with alcohol withdrawal symptoms, but alcohol drinking increases serum nitrite concentration influenced by general condition of the body.

This study was designed to examine the involvement of lead in function of target organ, and the protective effect of selenium in lead-treated guinea pigs for 8 weeks. The effects of exposure to 0.5% lead acetate(lead) and/or 4ppm sodium selenite(selenium) in feed on serveral aspects were evaluated by measuring thyroid stimulating hormone(TSH), triiodothyronine($T_3$), thyroxine($T_4$), serum biochemical activities, organ weights, and serum and organ lead concentrations in growing animals. The many indicators of endocrine function(TSH, $T_3$, and $T_4$ in serum), enzyme and biochemical activities(${\alpha}$-glutamyltranspeptidase, alkaline phosphatase, lactate dehydrogenase, triglyceride, creatinine, $Ca^{2+}$ in serum), and organ weights(kidney, spleen and testis) were correlated with lead exposure or showed significantly different mean values between the exposed and controls. These changes on some aspects were reversed by combination-fed of selenium, but did not statistically significant. The organ(kidney, liver, spleen, testis and brain) and serum lead concentrations of lead-fed group were clearly higher than that of controls. Selenium supplementation resulted in a significant protection against lead accumulation in liver and testis. These results suggest that lead can cause a toxic effect on several organ and that selenium seems to has a protective effect on specific reaction by lead-induced organic function toxicity.

This study was performed to evaluate the effects of available phosphorus (AP) levels with or without supplemental phytase on the performance, egg quality, and serum biochemical parameters of laying hens. A total of 540 laying hens (40-week-old) were housed in cages and assigned to 6 dietary treatments with 5 replicates each, for 20 weeks. The treatments consisted of 0.20%, 0.25%, and 0.30% AP diets with or without phytase supplementation. During the 20-week period, egg production was lowest in hens fed the 0.20% AP diet; however, phytase supplementation in the diet completely corrected the adverse effect (P<0.05). No consistent difference was observed in egg production between hens fed the 0.25% and 0.30% AP diets and those fed the 0.20% and 0.30% AP diets with phytase supplementation. Similarly, egg mass was lowest in the 0.20% AP diet-fed group, and no difference in egg mass was observed in the 0.25% and 0.30% AP diet as well as the phytase-supplemented diet groups; however, egg mass was improved in the phytase-supplemented diet groups(P<0.05). Egg quality traits did not differ with dietary treatments. Serum alkaline phosphatase level showed a linear decrease (P<0.05) in the phytase-treated groups with increasing AP levels; moreover, a numerically linear increase (P<0.05) in serum Ca and P levels was observed in the phytase-treated groups. The results of this study indicate that phytase supplementation in the diet of laying hens could increase egg production and may lead to greater mineral absorption.
