Pregnancy can cause immune system changes. It is characterized by a decrease in the activity of immunocompetent cells. The use of antibiotics was intended to combat pathogenic microorganisms, but antibiotics have negative effects on pregnant women. The use of antibiotics can be replaced with extracts of Elephantopus scaber and Sauropus androgynus because both plants have chemical compounds that act as immunomodulators. This study was aimed to determine the activity of lymphocytes B220+, TER119+, and GR-1+ on bone marrow pregnant mice given the combination of extracts of Elephantopus scaber and Sauropus androgynus after infected with Salmonella typhimurium. This research uses seven treatment groups name: (K-) 0.05% NaCMC without bacterial infection; (K+) 0.05% NaCMC infected by bacteria; (P1) E. scaber 200 mg.kg-1BW infected by bacteria; (P2) E. scaber 150 mg.kg-1BW and S. androgynus 37.5 mg.kg-1BW infected by bacteria; (P3) E. scaber 100 mg.kg-1BW and S. androgynus 75 mg.kg-1BW infected by bacteria; (P4) E. scaber 50 mg.kg-1BW and S. androgynus 112.5 mg.kg-1BW infected by bacteria; and (P5) S. androgynus 150 mg.kg-1BW infected bacteria. The initial dose of E. scaber and S. androgynus was 50 mg.kg-1. Each treatment has three repetitions, surgery performed on day 12th and 18th. Lymphocyte cells isolated from bone marrow, the obtained results were analyzed by flowcytometry and statistical analysis using SPSS 16.0 one-way ANOVA, Tukey test and path. Based on the results from ANOVA tables, the formulations on mice that can restore their normal conditions with B220+ cells is E. scaber 150 mg.kg-1BW and S. androgynus 37.5 mg.kg-1BW, TER119+ cells is S. androgynus 150 mg.kg-1BW, while the GR-1+ cells affected by the surgery. Those three dose formulations can be used to obtain the optimum value which can increase the number of lymphocytes and not harmful to the developing fetus.

In addition to a wide range of adverse effects on human health, toxic metals such as cadmium (Cd) can promote kidney damage. In this study, we proposed the toxicological properties of these metals which are partly related to lipid peroxidation and chlorinative stress. Thus our study aimed to measure the lipid peroxidation and chlorinative stress in kidney of rats exposed to Cd. The study was performed on 32 male rats (Rattus novergicus) weighing 300±10 grams with normal activity. Rats were acclimatized for a week before the treatment. The animals were divided into two major groups with one group for control (K0) and the other groups were exposed to 3 mg/L CdSO4 through the drinking water. The animals in each groups were divided again into two small groups with different time of exposure. The time of exposure are subacute (six weeks) and subchronic (eight weeks). After the exposure the kidney from all treated animals showed the significant increase of MDA and AOPP levels. In conclusion, subacute and subchronic exposure of Cd caused the kidney damage through lipid peroxidation and chlorinative stress, as shown by increasing of MDA and AOPP levels. Keywords: AOPP, Cadmium, Chlorinative Stress, Lipid Peroxidation, MDA

The effect of gibberellin at multiplication stage on somatic embryo growth and maturation and plantlet regeneration of tangerine (Citrus reticulata Blanco.) var. Batu 55 was assessed. Somatic embryo at globular phase was cultured on MT media + 30 gL-1 sucrose and various concentrations of gibberellin (0, 2, 4, 6, and 8 ppm). The somatic embryo was maturated on MT media + 500 ppm malt extract + 73 mM sorbitol + 73 mM galactose. Cotyledonary somatic embryo was regenerated into plantlet on MT media + 500 ppm malt extract + 30 gL-1 sucrose + 2 ppm GA3. The results showed that the addition of gibberellin in somatic embryo multiplication stage increased somatic embryo growth and maturation and plantlet regeneration of tangerine. Optimum concentration of gibberellin needed for somatic embryo growth was 4 ppm which yielded two-fold fresh weight compared to control. The percentage of maturation was very low below 5%. The addition of gibberellin in media at embryo multiplication stage slightly increased the percentage of maturation about 1-2%. Thirty percent of cotyledonary embryo was able to regenerate into plantlet. The addition of gibberellin in media at embryo multiplication stage increased the regeneration percentage, even the addition of 8 ppm gibberelline yielded regeneration percentage up to 70%.Keywords: gibberellin, growth, maturation, plantlet regeneration, somatic embryo

Diabetes mellitus is a disease in which the body loses its ability to provide tight regulation and maintain a dynamic interaction between the tissue sensitivity and insulin secretion by β cells. The impact of this dysfunctional mechanism is uncontrolled blood glucose levels that lead to hyperglycemia condition. Highly reactive free radicals have a strong involvement in the pathogenesis of diabetes mellitus, where one of its forming process may be triggered by hyperglycemia condition. Patients with diabetes mellitus itself vulnerable to endothelial dysfunction, which is caused by a decrease in circulating endothelial progenitor cells, and also a decrease in chemokines which play a role in affecting the activities of these cells. Hyperglycemia condition and free radical activity is a major cause of these endothelial progenitor cells dysfunction.The purpose of this study was to determine the role of VipAlbumin®, a supplement derived from Channa striatus albumin extracts in inhibiting the action of free radicals that are formed due to hyperglycemia condition, which can affect the increase in endothelial progenitor cells relative amount. This study used BALB/C mice that induced to undergo diabetes mellitus through streptozotocin injection intraperitoneally at 5-day old. Mice who have reached 4 week old and positive to diabetes mellitus (blood glucose levels > 200 mg.dl-1) will be administered with VipAlbumin® orally for 14 days. VipAlbumin® dosage was divided into 4 groups: positive control (without VipAlbumin®); 1st dose (0.01664 mg.gr-1 BW); 2nd dose (0.416 mg.gr-1 BW); 3rd dose (10.4 mg.gr-1 BW). The last step was flow cytometric analysis to determine the development of endothelial progenitor cells relative amount, which isolated from bone marrow. The variables measured in this study were the relative amount of CD34+ and SDF-1. Based to flow cytometric analysis, mice with VipAlbumin® administration did not show any significant improvement in CD34 relative amount when compared to the positive control. Relative amount of Chemokine SDF-1 itself, although only occur at the 3rd dose of VipAlbumin® treatment, has increased and significantly different from the positive control.

Diabetes mellitus is one of the common metabolic disorders with increasing prevalence during recent years with hyperglycemia as its characteristic. DM has been shown to be a state of free radicals over production resulted from hyperglycemia that can activate cellular signaling pathways transcription of factor NF-κB which stimulates the production of several inflammatory mediators andl lead to chronic inflammation. Chronic inflammation is implicated in β-cell damage and function and promotes apoptosis. EMSA Eritin is a polyherbal consisting of soy bean extracts, coconut water extract and red rice extract that assumed to be antidiabetic and anti-inflammatory. This study will assess the effectiveness of EMSA Eritin against inflammation in diabetes mellitus by measuring levels of NF-κB produced by immunocompetent cells in DM mice model. Streptozotocin 100 mg.kg-1 BW is used to induce diabetes mellitus in mice. Oral administration of EMSA Eritin was given for 14 days with dose of 0.3125 mg.g-1 BW, 3.125 mg.g-1 BW and 31.25 mg.g-1 BW. Data were analyzed using One-way ANOVA (p<0.05) and Duncan test using SPSS 16.0 for Windows. The results showed that EMSA Eritin can be used as an alternative therapy for the treatment of DM. The level of NF-κB in diabetic mice significantly decreased when the mice received EMSA Eritin. Keywords: Diabetes Mellitus, EMSA Eritin, NF-κB, ROS
