The use of co-chemotherapy agent was needed since there were some toxicities on the normal tissues caused by the use of doxorubicin. The root of Eurycoma longifolia Jack, a part of plant, has a potential activity as co-chemotherapy. This study aimed to determine the effect of co-chemotherapy of ethyl acetate fraction of E. longifolia Jack roots and doxorubicin against cell proliferation activity by AgNOR method and determine expression of Bax protein of breast tissue in rats induced by DMBA. The rats were divided into five groups: I (baseline), II (DMBA 20 mg/kgBW), III (DMBA, doxorubicin 1.12 mg/kg), IV (DMBA, fraction of 100 mg/kg), and V (DMBA, doxorubicin, fractions). All the rats were sacrificed at week 16. Their breast tissue was evacuated. Cell proliferation and expression was observed using AgNOR method and immunohistochemistry, respectively. Results showed the percentage of p-AgNOR obtained by the healthy group, DMBA group, DMBA+Doxorubicin group, DMBA+ethyl acetate fraction of E. longifolia Jack root group, and DMBA+Doxorubicin+Ethyl acetate fraction of E. longifolia group were 00%, 14.672.11%, 1.831.21%, 6.832.03%, and 4.080.95%, respectively. The percentage of Bax expression obtained by the healthy group, DMBA group, DMBA+Doxorubicin group, DMBA+ethyl acetate fraction of E. longifolia Jack root group, and DMBA+Doxorubicin+Ethyl acetate fraction of E. longifolia group were 68.821.52%, 26.863.25%, 44.492.06%, 80.923.27%, and 78.704.87%, respectively. Based on the results, it was concluded that co-chemotherapy agent of ethyl acetate fraction of E. longifolia Jack roots and Doxorubicin could inhibit proliferation and trigger apoptosis through Bax expression in breast tissue of rats induced by DMBA

The Thrift of Avian Influenza in Indonesia

The circulating H5N1 Highly Pathogenic Avian Influenza in chicken has created devastating problems in Indonesia since 2003. Although human cases of Avian Influenza could be exceptionally reduced, however, it remains unsettled in poultry. Phylogenetic analysis of H5N1 virus (2003–2011) revealed the introduction of a single ancestral of 2.1 HA clade before 2003. The enzootic clade subsequently evolved into fourth order with predominantly 2.1.3.2. Pathological lesions showed cyanotic wattle, torticollis and haemorrhage in chicken feet and multi-internal organs. However, the introduction of vaccination and stringent biosecurity resulted in milder manifestations compared to classical lesions. In 2012, unusual high mortality in duck farms revealed the introduction of exotic clade 2.3.2.1. Despite the inefficient transmission of avian virus to humans and experimental receptor binding of 2.3.2.1 virus that showed avian preference, substitution of N158D and E190D in HA gene indicates possible threat to humans. In the same year, the Government of Indonesia announced the introduction of H9N2. Furthermore, a recent publication (2018) has reported new reassortant between HPAIV H5N1 and LPAIV H3N8 with resulting virulence attenuation in chicken

Karagenin sebagai Model Inflamasi pada Kulit Punggung Mencit: Gambaran Makroskopik dan Histopatologis

This study aims to create a model of dorsal skin inflammation in mice using carrageenan with various concentrations. Forty-five female Swiss mice with the aged of 8 weeks were used in this study. These mice were divided into three groups of 15. Group I, II and III was given subcutaneous injection of 1%, 2% and 4% carrageenan respectively on the dorsum. Carrageenan was dissolved in 0.9% buffer saline with 0.1 mL volume injection. Prior to carrageenan injection, dorsal skin-fold thickness was measured using calipers and then was repeated every hour up to 6 hours. At the end of the sixth hour of measuring skin-fold thickness, animal was sacrificed, the dorsal skin was excised and then was fixed in 10% buffer formalin for histopathological examination. Data from skin-fold thickness measurement was analyzed using Two Ways Anova followed by Tukey HSD test. Results of this study demonstrate that there was a significant difference in skin-fold thickness between treatment groups (p<0.05). Sub cutaneous injection of 1%, 2% and 4% carrageenan resulted in increasing skin-fold thickness approximately 35%, 50% and 61% at the one-hour post carrageenan injection respectively (p<0.05). Skin-fold thickness gradually decreased at the second to the sixth hour after carrageenan injection. Histopathological examination shows mild and moderate dermal inflammation in the group given 1% and 2% carrageenan respectively. Severe dermal and panniculus inflammation was found in the group given 4% carrageenan. To conclude, carrageenan could be used to induce inflammation in back skin of mice
