Objective To evaluate the development of recurrent caries after exposure to fluoride dentifrices with different concentrations. Material and method: 48 samples of bovine incisors (4x4mm2) were exposed to pH cycling for 7 days before the preparation of the cavities (2mm deep). The samples were restored with a microhybrid resin composite. Then, the samples were exposed to thermal cycling (350 cycles) and they were randomly allocated into 4 treatment groups (n = 12): Group A - non-fluoridated dentifrice (negative control); Group B - 500 ppm dentifrice; Group C - 750 ppm dentifrice; group D - 1100 ppm dentifrice (positive control). The samples were treated with solutions of each dentifrice (9.6 ml water/1.6 g dentifrice) for 60 seconds and then were immersed in demineralizing (3 h) and remineralizing (2 h) solutions 3 times a day. Next, the samples were immersed in a remineralizing solution for 18 hours. Then, the blocks were sectioned for examination of the length of the outer caries lesion, using polarized light microscopy. The ANOVA parametric test complemented by the Tukey test with a confidence level of 95%, were used in the statistical analysis. Result: A smaller lesion length was observed in the group treated with the fluoride concentration of 1100 ppm F, but there were no differences between toothpastes with fluoride concentrations of 500 and 750 ppm F. Conclusion: The use of fluoride dentifrices (1100 ppm) reduces the development of caries adjacent to dental restorations.

A total of 75 day old broiler chicks were divided into three equal groups. Group A served as negative control. Group B (positive control) and C (treatment group) were intoxicated with oral administration of CCl4 @ 1 ml/kg body weight after every 3rd day during 15-28 days of age. Group C was given AV/LCP/18 @ 0.10 ml / chick / day in drinking water during 29th-42nd day of age. At the end of experiment, significantly (P is less than 0.01) higher mean body weight and lower FCR was observed in treatment group C as compared to positive control group B. Similarly, significantly (P is less than 0.05) decreased levels of SGOT, SGPT, cholesterol, triglycerides, creatinine and higher mean values of serum protein profile along with mild degenerative changes in liver and kidney of broilers in group C were observed as compared to group B indicating therapeutic efficacy of AV/LCP/18 in ameliorating the toxic effects or FLKS induced by CCl4 in commercial broilers

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.

Background: Foodborne diseases are caused by acquired pathogenic bacteria such as Salmonella enteritidis. It causes an intestinal imbalance and the microbial toxins found in the gastrointestinal tract induce symptoms such as diarrhea. Coffee contains active ingredients such as antioxidants and is used as an anti-inflammatory agent by reducing pro-inflammatory cytokine levels in the body. Aim: The purpose of this study was to determine the interaction between Lampung’s robusta coffee and tissue damage in chickens infected by S. enteritidis. Methods: This study used first-day-old Isa brown layer chickens (n = 60), which were divided into five treatment groups. The negative control group consisted of healthy and normal chickens, whereas the positive control group consisted of chickens infected with S. enteritidis bacteria at a concentration of 108 CFU/ml. Groups T1, T2, and T3 were given coffee extract with doses of 500 mg/kg BW (low dose), 1,000 mg/kg BW (moderate dose), and 1,500 mg/kg BW (high dose), respectively, and then infected with S. enteritidis bacteria at a concentration of 108 CFU/ml. The coffee extract and bacteria were given orally via a feeding tube at a volume of 0.5 ml per chick. The extract was given for 14 days (from day 3 to day 16), and the bacteria were given on days 16 and 17. On day 18, the chickens were necropsied. The malondialdehyde (MDA) level was analyzed using one-way analysis of variance test with the GLM procedure (<0.05), while the tissue histopath was analyzed using a descriptive qualitative study to examine the ileal damage Results: The results showed that the MDA levels (nmol/l) decreased in treatment groups T1, T2, and T3 compared to the positive control. On the contrary, we found improvements in the ileum histopathology of group T1 and T2 in the form of normal and regular intestinal epithelium arrangement of the ileum, long intestinal villi, and decreased total leukocytes. Conclusion: Green coffee robusta has the potential to increase antioxidants and reduce inflammation in the small intestine of chickens infected with S. enteritidis.

Gandarusa (J. gendarussa Burm. f.) is an etnomedicine which is used as a male contraceptive alternative, known to inhibit the enzymefunction of spermatozoa hyaluronidase during fertilization. One of the ideal contraceptive conditions is the safetyness (among others nonmutagenic), requiring a long research during the verification process. The early research is the gene expression of hyaluronidase mice(M.musculus L.) testis given water fraction of the gandarusa with PCR analysis. The total RNA was isolated from the normal mice testis(as the negative control or no treatment group) and the mice testis from the treatment groups. The treatment groups consisted of group Iand II treated with water fraction of the gandarusa 15 mg/20 gr BW and 7.5 mg/20 gr BW, subsequently, the positive control group wasalso given hesperidins 1 mg/20 gr BW once a day per oral during the 1.5 times of spermatogenesis cycle (for 55 days). The results of thestudy showed that (1) the cDNA fragment confirmed as the gene of hyaluronidase mice testis (with 710 bp length of nucleotide) passedthrough RT-PCR at the total RNA negative control group, sequenced, isolated and alignment in the NCBI gene bank. (2) the same cDNAfragment gene of hyaluronidase mice testis (from the negative control group) did not transcript in the treatment I and positive controlgroups (where there is no band), but this gene will be transcripted in the treatment II group (where the band is emerged).

Abstract The efficacy of intramuscular administration of Homidium chloride (Novidium®) and Isometamidium chloride (Sécuridium®) in Nigerian donkeys (Equus asinus) experimentally infected with T. b. brucei (Federe isolate) was investigated. Changes in haematological and serum biochemical indices were evaluated using clinical haematology and biochemistry methods. Red blood cell (RBC) count for the negative control group was significantly higher than for the positive control, Novidium® and Sécuridium®-treatment groups. Haemoglobin (Hb) concentration significantly reduced in the infected untreated group compared with other groups. Packed cell volume (PCV) was significantly different between negative and positive controls, and also between the infected untreated and treatment groups. There was significant reduction in platelet counts post-infection and post-treatment. Mean corpuscular volume (MCV) increased significantly in the treatment groups while mean corpuscular haemoglobin concentration (MCHC) significantly reduced only in the Sécuridium®-treatment group. Lymphocyte count for infected untreated was non-significantly higher than for the uninfected controls, but treatment with both trypanocides recorded further increases, which were higher compared with that of the uninfected group. Post infection and treatment, aspartate aminotransferase (AST) levels increased significantly. There were non-significant differences in electrolyte ion concentrations across the groups except for chloride ion which recorded a significant reduction in the Novidium®-treatment group. This experiment revealed that Nigerian donkeys infected with T. brucei brucei (Federe isolate) developed symptoms of trypanosomosis; anaemia, lymphocytosis and thrombocytopenia. Treatment with the trypanocides ameliorated effects of the infection, and results suggest that immunosuppression may not be a substantial clinical manifestation of T. brucei brucei (Federe isolate) trypanosomosis in Nigerian donkeys.
