Objective: The prophylactic and antioxidative role of the dried powdered of Ocimum sanctum (Tulasi) was measured in Hexamita-infected fish Anabas testudineus. Method: Four groups of infected fish were kept in four separate aquariums and the following doses of leaf powder applied (25 mg, 50 mg, and 100 mg/L) for 10 days, and the first group is considered as control and no such treatment is given there. Results: Histopathology showed a remarkable alteration in the structure of liver tissue. Progressive changes observe along with the treatment schedule in hepatic histology and differential count of blood. Results showed that Hexamita infections significantly increased (p<0.05) the oxidative stress in the liver of infected fish. Whereas the treated fish exposed to different doses of powdered leaf of O. sanctum show significantly higher levels of antioxidant enzymes (Catalase, Superoxide dismutase, Glutathione peroxidase) and lower levels of stress marker (Malondialdehyde) than control fish. This treatment caused a rapid skin formation in the scar region. The highest recovery found in 100 mg/L doses of leaf powder, whereas the least recovery found in 25 mg/L group. Conclusion: The findings of the present study may play a key role in aquaculture industry for controlling the death of fish from Hexamita infection.

Novel Virus

: SARS-CoV 2 is a novel virus strain of Coronavirus, reported in China in late December 2019. Its highly contagious nature in humans has prompted WHO to designate the ongoing pandemic as a Public Health Emergency of International Concern. At this moment, there is no specific treatment and the therapeutic strategies to deal with the infection are only supportive, and prevention aimed at reducing community transmission. A permanent solution for the pandemic, which has brought the world economy to the edge of collapse, is the need of the hour. This situation has brought intense research in traditional systems of medicine. Indian Traditional System, Ayurveda has a clear concept of the cause and treatment of pandemics. Through this review, information on the potential antiviral traditional medicines along with their immunomodulatory pathways is discussed. We have covered the seven most important Indian traditional plants with antiviral properties :Withaniasomnifera (L.) Dunal(family: Solanaceae),Tinosporacordifolia(Thunb.)Miers (family:Menispermaceae),Phyllanthusemblica L.(family:Euphorbiaceae),Asparagus racemosus L.(family:Liliaceae), Glycyrrhizaglabra L.(family:Fabaceae), Ocimum sanctum L.(family:Lamiaceae) and Azadirachta indica A.Juss(family:Meliaceae)in this review. An attempt is also made to bring into limelight the importance of dietary polyphenol, Quercetin which is a potential drug candidate in the making against the SARS-CoV2 virus.

Porcine Somatotropin

The effects of porcine growth hormone on growth and salinity tolerance were studied in Atlantic salmon (Salmo salar) parr. Fish were held in freshwater at 11.5 °C during June and July under a photoperiod with light to dark periods opposite to the prevailing natural conditions. Fish treated with 1.0 μg/g body weight of growth hormone preparation on alternate days were significantly longer (P <.05), after 4 weeks, than placebo-injected controls. All hormone-injected fish survived transfer to seawater, 30‰ salinity. But under the same conditions, placebo-injected control fish showed a high mortality rate. Growth-hormone treatment caused a darkening of fin margins and a yellowing of the operculae and fin surfaces. The silvering which normally accompanies smoltification was not observed. The role of growth hormone in eliciting these actions and its possible role in the parr–smolt transformation are discussed.

Preliminary sampling revealed the presence of furunculosis disease in the resident brook trout population of the southern Ontario trout stream used in this study.Two plantings of marked yearling brook trout were made in the study area in 1966; one in the spring, and the other in the fall. The spring planting consisted of 1000 brook trout with a predetermined incidence of furunculosis infection and an equal number of trout with no evidence of infection. The fall planting consisted of 2000 brook trout with a known incidence of furunculosis infection.The stream was electrofished periodically during the 2-year period after the first planting. A total of 445 brook trout (140 of the planted hatchery stock, and 305 resident trout) and 127 fish of associated species were captured and examined for the presence of Aeromonas salmonicida, causative agent of furunculosis.Recovery rates of the "infected" and "noninfected" stocks of brook trout were similar, and there was no evidence of transmission of A. salmonicida from the infected fish to the control fish, nor the resident population of brook trout and other species of fish captured.

Background: Medicinal plants constitute an important source of potential therapeutic agents for diabetes.Objective: In the study, we aimed to investigate the pre-treatment effect or preventive effects of Moringa oleifera (MO) leaves on blood sugar of rats.Materials and method: This experimental study was carried out in the department of Pharmacology and Therapeutics of Sir Salimullah Medical College in collaboration with Bangladesh Council of Scientific and Industrial Research (BCSIR), Dhaka. A total 24 long Evans rats were included in this study and divided in to four groups. Hyperglycemia was induced on rats using alloxan (100 mg/kg body weight, intraperitioneally). Blood sample was collected from tail vein by tail tipping method. Pre-treatment effect or preventive role of Moringa oleifera (drumstick) leaf powder on diabetogenesis produced by Alloxan in rats was tested by giving 50 mg/rat/day Moringa oleifera leaf powder for 14 days orally as pre-treatment along with standard rat feed. Then alloxan was administered intraperitoneally on 15th day of the experiment and 50mg/rat/day Moringa oleifera leaf powder was given for 7 days as post-treatment.Results: No significant effect of MO on blood glucose level was observed on normal rats and non significant hypoglycaemic effect was found in rats that were pretreated with MO.Conclusion: The present study suggests that Moringa oleifera leaf powder did not produce any significant protective effect in diabetogenesis produced by alloxan though it has hypoglycaemic effect.Delta Med Col J.

Abstract Parasites are arguably among the strongest drivers of natural selection, constraining hosts to evolve resistance and tolerance mechanisms. Although, the genetic basis of adaptation to parasite infection has been widely studied, little is known about how epigenetic changes contribute to parasite resistance and eventually, adaptation. Here, we investigated the role of host DNA methylation modifications to respond to parasite infections. In a controlled infection experiment, we used the three-spined stickleback fish, a model species for host–parasite studies, and their nematode parasite Camallanus lacustris. We showed that the levels of DNA methylation are higher in infected fish. Results furthermore suggest correlations between DNA methylation and shifts in key fitness and immune traits between infected and control fish, including respiratory burst and functional trans-generational traits such as the concentration of motile sperm. We revealed that genes associated with metabolic, developmental, and regulatory processes (cell death and apoptosis) were differentially methylated between infected and control fish. Interestingly, genes such as the neuropeptide FF receptor 2 and the integrin alpha 1 as well as molecular pathways including the Th1 and Th2 cell differentiation were hypermethylated in infected fish, suggesting parasite-mediated repression mechanisms of immune responses. Altogether, we demonstrate that parasite infection contributes to genome-wide DNA methylation modifications. Our study brings novel insights into the evolution of vertebrate immunity and suggests that epigenetic mechanisms are complementary to genetic responses against parasite-mediated selection.

AbstractAn in vitro assay was used to examine the effect of Bothriocephalus acheilognathi Yamaguti, 1934 (Cestoda: Pseudophyllidea) on the polarization response of pronephric leucocytes of carp, Cyprinus carpio. Leucocytes, isolated from naive, naturally-infected fish and carp injected intraperitoneally with cestode extracts, were exposed to parasite extracts (protein concentrations 0–10.0 μg ml-1), for up to 24 h in the presence or absence of carp serum. In general, polarization responses of the pronephric leucocytes, primarily neutrophils and eosinophils, increased with incubation time although there was no significant difference in the response induced by the different protein concentrations. Differences in the polarization response were, however, observed in naive, naturally infected and injected fish and the cells responded differently in the presence and absence of carp serum. In the absence of carp serum the polarization response of pronephric leucocytes in vitro was significantly reduced with cells obtained from injected and naturally infected fish compared with those obtained from naive carp. This suppression of leucocyte migration was however reduced by the addition of carp serum to the in vitro system. The role of this interaction between the possible suppression of polarization induced by the parasite and stimulation by serum is discussed.
