BACKGROUND: Based on the Biopharmaceutics Classification System (BCS) system, irbesartan is a drug that belongs to the class II BCS group which has limitations in terms of dissolution rates with low bioavailability of 26% -60%. These limitations to bioavailability can be overcome by solid dispersion with hydrophilic matrices such as Poloxamer. Irbesartan is an angiotensin receptor blocker. At present, it is widely used in dealing with hypertension due to endothelial dysfunction. AIM: This study aims to determine endothelial function blood markers can be examined, such as adhesion molecules (ICAM-1) and IL-8 pro-inflammatory cytokines. MATERIAL AND METHODS: Research on the effects of irbesartan-poloxamer-188 solid dispersion on ICAM-1 and IL-8 in hypertensive rats has been carried out. The formation of solid dispersion through dissolution method while induction of hypertension using 2.5% NaCl and prednisone 1.5 mg/Kg BB orally in 3 treatment groups, irbesartan dose was 13.5 mg/kg. The parameters observed were serum ICAM-1 and IL-8 levels. RESULTS: The result showed that the solid dispersion of irbesartan-poloxamer-188 could reduce ICAM-1 and IL-8 levels in hypertensive rats which differed significantly from the positive control group (p < 0.05). CONCLUSION: This study concluded that the solid dispersion of irbesartan-poloxamer-188 effects and decreases ICAM-1 levels in the serum of hypertensive rats. Solid dispersion of irbesartan-poloxamer-188 can influence and reduce IL-8 in the serum of hypertensive rats.

Contaminated water often affects the occurrence of periodontitis in the coastal area. The diabetic hypercholesterolemia-induced periodontitis in Indonesia is very high. The use of coenzyme Q10 to treat this disease has never been investigated yet. Therefore, this study aimedto analyze the effect of coenzyme Q10 on the lipid profile of diabetic hypercholesterolemia-induced periodontitis.Twenty four rats were randomized into 6 groups (G1-G6). The groups (G1-G3) are healthy, negative and positive control group respectively. The treatment groups (G4-G6) are diabetic hypercholesterolemia-induced rats given coenzyme q10 dose of 13,5; 27 and 54 mg/kg respectively. Rats were induced by periodontitis, hypercholesterolemia and diabetes mellitus. Coenzyme Q10 was administered orally using 2 mL gastric tube once a day for 14 days. Lipid profile including triglycerides, HDL, and atherogenic index (IA) was measured enzymatically by the CHOD-PAP method. Data were analyzed by one-way ANOVA test and followed by the Least Significant Difference (LSD) post hoc test.Coenzyme Q10 with a dose of 54 mg/kgis effective in lowering triglyceride, and atherogenic index and increasing HDL level in diabetic hyperlipidemia-induced periodontitis rats model. This research supports the potential effects of coenzyme Q10 supplementation to improve lipid profile in diabetic hypercholesterolemia-induced periodontitis in the coastal area.

Piper sarmentosum is a tropical plant in Southeast Asia known for its traditional use in curing various ailments including hypertension. Previous research works have provided evidence for the herb’s antihypertensive property. However, the exact mechanisms involved are still in question. The present study investigated the effects of Piper sarmentosum leaves aqueous extract (PSAE) treatment on vascular endothelin system in spontaneously hypertensive rats (SHRs). Four groups of SHRs were treated for 28 consecutive days, with negative and positive control groups receiving distilled water and 3 mg/kg perindopril, respectively. Another two groups are the treatment groups, which received PSAE and combination of 1.5 mg/kg perindopril and PSAE. Weekly measurements of blood pressure showed that PSAE significantly reduced the systolic, diastolic, and mean arterial pressures (P<0.05) of the rats. PSAE also increased mesenteric artery nitric oxide (NO) level (P<0.05) and reduced endothelin-1 (ET-1) level (P<0.05) in the treatment groups. Our results demonstrate that oral administration of PSAE reduced blood pressure in SHRs by reducing the ET-1 level while increasing NO production.

Antidiabetic activity of Vernonia amygdalina and its possible synergism with glibenclamide was checked. Forty eight rats were used for the research, for hypoglycermic study of V. amygdalina alone, they were grouped into five of six rats each. Group 1 was the negative control and was administered distilled water orally. Groups 2, 3, and 4 were the treatment groups which received 100, 200 and 300 mg/kg body weight of the V. amygdalina extract respectively orally by intubation. Group 5 was the positive control group which received a known antidiabetic drug, glibenclamide. Diabetes was induced with alloxan. For the synergism study, another 18 rats grouped into 3 of six rats each was used. Both groups of glibenclamide only and glibenclamide plus V. amygdalina extract were dosed for 14 days orally by intubation, thereafter were sacrificed and blood collected from heart for analysis. There were 5 replicates grouped by weight throughout the study and both single and synergistic studies had the same controls. Effect of V. amygdalina extract was checked on blood glucose and its possible synergism with glibenclamide. All results in treatment groups were compared with the normal control at statistical confidence of p<0.05. Result shows that V. amygdalina extract reduced blood glucose level in the test groups as dose of extract increased. Combination of V. amygdalina with glibenclamide demonstrated further deduction in blood glucose levels in the treatment rats groups. Therefore addition of V. amygdalina into glibenclamide increased efficacy in the diabetic rats. The interaction between V. amygdalina and glibenclamide in this work was additive and therefore synergistic.

Background: The god’s crown fruits have properties as antioxidants and anti-inflammatory. Toxic doses of paracetamol can injure the liver through toxic metabolite bonds with cytoplasmic proteins that cause free radicals to form. The aim of this research is to know the effect of the crown of gods extracts on paracetamol hepatotoxicity. Method: A total of 30 of Webster swiss mice with a weight of ± 20 grams, age 3 months were randomly assigned to five groups, negative control, positive control, treatment 1,2 and 3. A 70% ethanol extract of god’s crown fruit given in doses 60mg, 120mg and 240mg per kgBB mice. The extract was administered for 14 days in the treatment groups, then on day 15 paracetamol ware administered in a given dose 300mg/kgBB for 1 day for the positive control group and treatment groups. On day 16, the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were examined from the orbital sinuses and animals terminated liver tissues taken and immediately fixed in 10% buffer formalin for histological examination. Results and Discussion: The 70% ethanol extract of the god’s crown fruits decreased blood serum levels of AST and ALT, and these results were supported by histopathologic scores of the liver in which histopathologic scores were improved with the increasing doses (p < 0.05). The secondary metabolite contents of the god’s crown fruit extract served as an antioxidant and anti-inflammatory, protecting hepatic injury from the toxic metabolite of paracetamol. Conclusion: A 70% ethanol extract of god’s crown fruit (Phaleria macrocarpa) have hepatoprotective properties that effectively prevent hepatic injury due to paracetamol toxic dose.

Background and Purpose: Shigella is a human shigellosis and its lipopolysaccharide is identified by 4TLR. The 4TLR is a family of pseudo-TOLL receptors and many immune routes are triggered by stimulating these receptors. Many studies show increasing of 4TLR expression in Mesenchyme stem cells under the influence of lipopolysaccharide. The main objective of this study was to identify the appropriate lipopolysaccharide of Shigella strains by stimulating the immune system for vaccine studies. Materials and Methods: In this experimental study, the stem cell of human Mesenchymal derived from bone marrow was treated by three dilution of 0.1, 0.01, and 0.001 extract of Shigella strains (Flexneri, Dysentery and Sonnei) containing lipopolysaccharide. Then, the expression of 4TLR at RNA level was evaluated by RT-PCR and Q-PCR techniques. Cells treated with phosphate buffer saline were considered as control group. Findings: The expression of 4TLR was observed in all treatments groups except for treatment groups with relative concentration of 0.001 sonnei and dysentery as well as control group. Changes in 4TLR expression were dose-dependent on all treatment groups. The highest expression was related to the treatment with Shigella Flexneri extract and the smallest was related to Shigella sonnei. The use of pure lipopolysaccharide of Escherichia coli as a positive control showed that the lipopolysaccharide in Shigella extract is responsible for increasing the expression of 4TLR. Conclusion: given the increased expression of 4TLR by Shigella extract, this extract is recommended to increase the efficacy of the vaccine.

Objective: Vasculitis is the basic pathological change of systemic lupus erythematosus (SLE). Radix Paeoniae Rubra (RPR), a traditional Chinese herb with the function of reducing blood stasis, has anti-inflammatory and immunoregulatory properties. This study explored the effects of RPR on the kidneys of lupus-like symptoms of mrl (MRL/lpr) mice from the perspective of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and platelet endothelial cell adhesion molecule-1 (PECAM-1). Methods: Eighteen MRL/lpr lupus model mice were randomly divided into three groups, the model control group, prednisone-treated group, and RPR-treated group, and 6 C57BL/ 6 mice were classified as a control group. After the mice had been treated for 12 weeks, the expression of ICAM-1, VCAM-1 and PECAM-1in the kidney was determined by immunohistochemistry and Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Results: After 12 weeks, there were significant differences in body weight in the model, prednisone and RPR groups compared with the normal group (P <0.05). Pathological observation: Compared with the model group, the proliferation of inflammatory cells infiltrated glomeruli and interstitial cells in prednisone and RPR groups were reduced, and renal pathological damage was reduced. Compared with the model group, urine protein level of prednisone and RPR groups were reduced with no significance (P> 0.05). The mRNA expression levels of ICAM-1 and VCAM-1 were significantly reduced in the prednisone group and RPR group compared with the model group (P <0.05 or P <0.01). Meanwhile, the immunohistochemistry expressions of ICAM-1 and VCAM- 1 expressed in the kidney were significantly reduced in the prednisone group and RPR group (P <0.01 or P <0.05). However, The mRNA expression level and the immunohistochemistry expressions of PECAM-1 expressed in the kidney were reduced in each treatment group (prednisone group and RPR group), but these differences were not significant (P>0.05). Conclusions: ICAM-1, VCAM-1 and PECAM-1 expression in the model group was found to be significantly increased. In addition, RPR could reduce the expression of ICAM-1, VCAM-1 and PECAM-1 in MRL/lpr lupus mice as effectively as prednisone, which may result in the dosage reduction of prednisone, thus decreasing the toxicity and improving the efficacy of prednisone - based treatment of SLE.

Abstract Osteoporosis is a bone disease characterized by decreased quality and strength of bones so that it becomes porous and fracture. Propolis is known to have many pharmacological activity, including an anti-osteoporosis effect. This study aims to determine the effect of propolis administration and the effects of propolis dosage variation in preventing osteoporosis based on the strength value of femur bone impact in female white rats in the form of an ovariectomy postmenopausal model. The rats were divided into 5 groups: positive control group (subjected to ovariectomy), negative control group (not subjected to ovariectomy, and treatment groups that were subjected to ovariectomy and given propolis at a dose of 180 mg/kg BW, dose 360 mg/kg BW and dose 720 mg/kg BW. Propolis was administered orally for 30 days. Bone impact strength testing was undertaken after 30 days using an impact testing machine. Research data were analyzed via one-way ANOVA and continued with the Duncan’s Multiple Range Test. From the test results, we noted that propolis administration had an effect on the value of bone strength, with the dose of 720 mg/kg BW and 360 mg/kg BW having a significant effect, compared with others. With an increase in dose, propolis can provide an increase in the value of bone strength in rat bones.
