A total of six clinical cases of snake bite were examined clinico-haematologically. The clinical examination revealed the normal rectal temperature but increased respiration as well as heart rates. The hematological values showed decreased Hb and PCV but increase in polymorphonuclear cells. All these snake bite dogs had been successfully treated with slow i.v. administration of antivenin along with corticosteroids i.m., adrenaline (1: 10,000 dilution in i.v. fluid), inj. DNS (5%), i.m. administration of antibiotic(s) and local antiseptic dressing with povidone Iodine after irrigation or washing the affected area(s) with soap water. Out of six dogs, four dogs survived and two died even after treatment.

A dead calf with cranial duplication removed by cesarean section under local infiltration anaesthesia. The cow made uneventful recovery after surgery without complication.

A total of 128 faecal samples of dogs suspected for canine parvovirus infection were examined by Haemagglutination (HA) and Haemagglutination inhibition (HI) tests. The prevalence of canine parvovirus infection was 45.30% (58/128) and the age wise maximum (70.20%) prevalence was found in dogs upto 6 month. The breed wise maximum (56.90%) prevalence was in Non-descript dogs and sex wise prevalence revealed no significant difference in male (45.9%) and female (43.3%).

Effect of strain (Khaki Campbell, Indigenous) and age (224 and 280 days) of ducks on the physical egg quality and presence of off-flavour in eggs was studied. The average of egg weight, yolk index and percent yolk weight for the two ages under study were significantly (P0.05) higher in Indigenous duck eggs whereas the same average value for albumen index, Haugh Unit score and percent albumen were higher in Khaki Campbell eggs. However, shape index, yolk colour score, shell thickness and percent shell weight of eggs were comparable for the two strains. Age of ducks had an insignificant influence on shape index, albumen height, shell thickness and yolk index as evident from the least difference between average values of two strains under study. But, the average values of the two strains under study were significantly affected by age for A.I., H.U. score, % albumen weight, % shell weight and % yolk weight. Presence of off-flavour was more pronounced in Khaki Campbell eggs than that of indigenous eggs.

Rabies virus (RV) is highly neurotropic and migrates to the neuronal soma by retrograde axonal transport from nerve terminals, after which it is taken by anterograde axonal transport to be finally released into the central nervous system (CNS) from which it disseminates, resulting in lethal encephalitis. Dorsal root ganglia (DRG) are crucial in the initial events of the infection by RV since they can act as a gate for the viral entrance into the CNS. In the present study, we examined cell tropism of RV and the roles of neuronal cytoskeletal components in the production of viral nucleoprotein (N protein) using cultured nerve cells and non-neuronal cells from DRG of newborn mice. Our in vitro study demonstrated a low propagation rate of RV in nerve cells, susceptibility of non-neuronal cells to RV, and independence of cytoplasmic synthesis of viral N protein from the neuronal cytoskeleton. The present study also suggests that Schwann cells should be considered as another possible candidate supporting RV propagation.

Test vaccines comprised of inactivated water-in-oil emulsions containing various antigen levels were prepared using a non-pathogenic H5N1 avian influenza (AI) virus, A/duck/Hokkaido/Vac-1/04 (H5N1). The potencies of these test vaccines were evaluated by two experiments. In the first experiment, the triangular relationship among the antigen levels of test vaccines, the hemagglutination inhibition (HI) antibody response, and the protective effect against challenge with a highly pathogenic avian influenza (HPAI) virus, A/chicken/Yamaguchi/7/04 (H5N1), was confirmed. Then lasting immunity of chickens after a single-shot vaccination was confirmed in the second experiment. As a result, complete protection after the challenge was observed in chickens immunized by test vaccines with an antigen level of 160 HA units/dose or higher. Thus, it was ascertained that the minimum antigen level in the AI vaccine was 160 HA units/dose, and the minimum HI antibody titer that could protect chickens from HPAI virus infection-related death was considered to be 1:16. Dose-dependent HI antibody responses were observed in chickens after the vaccination. Thus, 640 HA units/dose were thought to be similar to the optimal antigen level. Alternatively, the HI antibody titers of chickens, injected with the vaccine containing 640 HA units/dose, were maintained at 1:181 or higher for 100 weeks after the single-shot vaccination.

Pleurotus cornucopiae (PC) mushrooms are found in the field and commonly known in Japan as Tamogidake mushrooms. The present study investigated the protective effects of an aqueous extract of PC on carbon tetrachloride (CCl4)-induced hepatotoxicity and the possible mechanism involved in this protection including cytochrome P450 (CYP) 2E1. Wistar rats were pretreated with aqueous extracts of PC (0, 100, 200, and 400 mg/kg) orally for 8 days prior to the intraperitoneal administration of a single dose of CCl4 (0.5 ml/kg) or corn oil. Pretreatment with PC mushroom extract significantly prevented the increased serum enzyme activities of alanine and aspartate aminotransferases in a dose-dependent manner, and suppressed the expression of CYP2E1. PC mushroom extract also protected hepatocytes from the damage effects of CCl4 as remarked by histological and electromicroscopical findings. It was concluded that repeated daily doses of aqueous extracts of PC mushroom reduced the toxic effects exerted by CCl4 on the liver.

To characterize the roles of C-peptide in vascular homeostatic processes, we examined the genes regulated by C-peptide in LEII mouse lung microvascular endothelial cells. Treatment of the cells with C-peptide increased the expression of c-Jun N-terminal kinase 1 (JNK1) mRNA dose-dependently, accompanied by an increase in JNK1 protein content. Prior treatment of the cells with PD98059, an ERK kinase inhibitor or SB203580, a p38MAPK inhibitor, abrogated the C-peptide-elicited JNK1 mRNA expression. These results indicate that C-peptide increases JNK1 protein levels, possibly through ERK- and p38MAPK-dependent activation of JNK gene transcription.

The activity concentrations of sup(40)K, sup(238)U, sup(232)Th and sup(137)Cs were measured using gamma spectrometric method in different food chain samples from Serb Belgrade environment during the periods May-June 2007 and May-June 2008 year. Relatively high activities of sup(40)K and sup(137)Cs were detected in the soil. These results indicate that sup(137)Cs is present in Belgrade environment even 20 years after nuclear accident in Chernobyl. However, in the samples of feedstuffs, animal products and bio indicators (meat of wild animals and fish), activity concentrations of primordial radionuclides and sup(137)Cs were low and below the detection limits. Results of these trials have shown that investigated animal products from the natural environment around Belgrade, are radioactivity safe.

The aim of this study was to improve the clinical evaluation in sea turtles by analyzing the hemogram and serum biochemistry in female loggerhead sea turtles (Caretta caretta), free-ranging (n=22) nesting in the north coast of Bahia and in the animals captivity (n=5) in the visitor center of the Projeto Tamar-ICMBio, in Praia do Forte, Bahia, Brazil. The values obtained were compared between the two groups and it was observed that there was statistically significant difference (p<0,05) for the relative and absolute eosinophil count, relative monocyte count, total serum protein, globulin, glucose, cholesterol and aspartate aminotransferase. The results variation is probably related to the differences in environmental, nutritional and reproductive conditions. | Com o objetivo de se obter dados que auxiliem na rotina clínica de tartarugas marinhas, realizou-se o hemograma e a determinação de alguns parâmetros bioquímicos séricos de fêmeas de tartarugas cabeçudas (Caretta caretta) de vida livre (n = 22), animais que desovam no Litoral Norte da Bahia, e em cativeiro (n = 5), animais mantidos no Centro de Visitantes do Projeto Tamar-ICMBio, na Praia do Forte, Brasil. Os valores obtidos para os dois grupos foram comparados, onde se observou diferença estatística significativa (p<0,05) para as contagens relativas e absolutas de eosinófilos e contagem relativa de monócitos dentre as variáveis do hemograma e, para a proteína total, globulina, glicose, colesterol e aspartato aminotransferase. Possivelmente, diferenças nas condições ambientais, nutricionais e reprodutivas, as quais estes animais foram submetidos, influenciaram nos resultados.
