BACKGROUND: The carcinogen dimethylbenzanthracene (DMBA) is immunotoxic. Thymoquinone, meanwhile, is known to have antioxidant and anti-inflammatory effects. AIM: This study aims to determine the effect of thymoquinone and tamoxifen on the CD4CD25Treg count in Sprague-Dawley (SD) rats induced by DMBA. METHODS: The 50 SD rats were divided into five groups. Group I (normal control) was given standard drinking and food. Group II was given thymoquinone, Group III was given tamoxifen, Group IV was given DMBA, and Group V was given solvent control. Thymoquinone, tamoxifen, and solvent control administration started 2 weeks before DMBA administration and continued during DMBA induction. In the 3rd week, except for the normal group, all groups were created to be induced with 10 × 20 mg/kg body weight of DMBA for 5 weeks. In the 21st week, surgery and data collection were performed. The hematology profile and CD4CD25Treg number were carried out employing a flow cytometer. The difference in the average number of CD4CD25Treg and blood cells between groups was analyzed with one-way analysis of variance RESULTS: The results revealed that DMBA induction reduced the number of erythrocytes, HB levels, platelet counts, and leukocyte counts (p < 0.05). The administration of thymoquinone and tamoxifen reduced the hematopoiesis effect of DMBA. The thymoquinone and tamoxifen group had a higher number of CD4CD25Treg and leukocytes than the DMBA group (p < 0.05). CONCLUSION: There was no difference in the average CD4CD25Treg, leukocyte count, lymphocyte count, and monocyte count between the thymoquinone and the tamoxifen groups (p > 0.05).

Abstract Background Development of drug-induced hepatic damage (DIHD) during chemotherapy is the most common reason for interruption in chemotherapy. This study evaluated the hepatoprotective activity of the ethanolic extract of Tamarindus indica stem bark (EETI) against the induced DIHD in Sprague Dawley rats. Methods The rats were divided into five groups (n=5). Group I, group III, group IV, and group V rats received 1 mL 1% carboxymethyl cellulose, EETI 100 mg/kg body weight (b.wt), EETI 200 mg/kg b.wt, and silymarin 100 mg/kg b.wt, respectively, orally once every day for 28 days. After 1 h–group II, group III, group IV, and group V rats were administered with isoniazid (INH) and rifampicin (RIF) 50 mg/kg b.wt each orally once every day for 28 days. Then, 24 h after the last dosing, blood was withdrawn from the rats and analyzed for liver specific enzymes and biochemical markers. They were examined for histopathology. Results Co-administration of INH and RIF in group II significantly increased alanine transaminase, aspartate transaminase, alkaline phosphatase, lactate dehydrogenase, serum bilirubin, and cholesterol levels while reduced the total protein and albumin levels compared to that of group I. EETI in group III and group IV rats significantly restored the liver specific enzymes and biochemical markers altered due to co-administration of INH and RIF to normal in a dose-dependent manner. EETI 200 mg/kg b.wt showed better protection to liver than EETI 100 mg/kg b.wt and was comparable to silymarin 100 mg/kg b.wt. It was well supported with histopathology of liver tissues. Conclusions EETI possesses hepatoprotective activity against DIHD in rats. It may have a substantial impact on developing clinical strategies to treat patients with hepatic damage.

Osteoporosis has become a major public health concern, due to its rising incidence every year. Osteoporosis mostly occurs in women at menopause, especially in Asia. Secang (Caesalpinia sappan L.) heartwood contains brazilin and brazilein which are known to suppress expression of NF-ĸB, an osteoclastogenesis protein playing an important role in osteoporosis.  Thus, the aim of this research is to investigate the inhibition of osteoporosis by ethanolic extract of secang (Caesalpinia sappan L.) (EES) in ovariectomized (OVX) rats. Thirty female Sprague Dawley rats were divided into five groups treated for 20 days:  group I were OVX and treated with 1000 mg/kgBW EES; group II were OVX and treated with 500 mg/kgBW EES; group III were OVX and treated with CMC-Na; group IV were shame OVX baseline; and group V were non-OVX-baseline. Bone density was examined by using X-Ray rontgen and was strengthen by qualitative data of Giemsa staining. Moreover, total number of osteoclasts in bone slide was observed by TRAP expression using double staining immunohistochemistry with hematoxylin eosin (HE) – TRAP. Treatment of 500 mg/kgBW EES in ovariectomized rats showed the highest bone density of 0.60 gr/cm3 and the lowest number of osteoclasts was 4.66 osteoclasts per field of view. These results showed that EES is potent to be developed as an antiosteoporosis agent. Further study on its dose adjustment and molecular mechanism needs to be conducted.Keywords: Caesalpinia sappan L., osteoporosis, RANK, bone density

Ethane in alveolar expirate may have its source in organs other than the lung and be transported to the lung for elimination. We determined ethane production rates in rats (group I) ventilated with hydrocarbon-free air (HFA) before and after exsanguination. To determine whether the lung is the source of increased ethane production during exposure to 100% O2, we measured ethane in the expirate of nine exsanguinated, Sprague-Dawley rats (group II) mechanically ventilated with HFA and then with 100% O2. In all nine animals, ethane elimination rates on 100% O2 increased compared with HFA values. In five of the nine rats, HFA ventilation was reinstated after O2 (group III). In all five, ethane elimination fell with HFA ventilation compared with the value on 100%. Six rats with circulation intact were ventilated with HFA and then 100% O2 (group IV). Ethane production rate for group IV animals breathing HFA was not significantly different from the exsanguinated animals in group II while ventilated with HFA. The mean increase in ethane production for the group II animals was not significantly different from the group IV animals. Lung slices from four other rats (group V) were incubated in saline at 37 degrees C with FeCl2 (10 mg) added to enhance free radical formation. Paired lung samples from the same rat were incubated with either HFA or 100% O2. Headspace gas was analyzed chromatographically for ethane at 120 min. Mean ethane in the O2 samples was higher than for HFA. Rat lung tissue is the main source of increased ethane production during 100% O2 exposure.

Abstract Cholesterol is needed in certain concentration as to avoid health effects. Efforts to handle hypercholesterolemia can be done by utilizing the content of resistant starch in Uter bananas flour. The aim of this study was to prove the hypocholesterolemic effect of Uter Banana flour in hypercholesterolemic Spraque-Dawlwy rats. Therefore, experimental research using animals to determine the hypocholesterolemic effect of Uter banana flour was carried out for 28 days, in Spraque Dawlwy male rats aged 2 months, weighing ± 200 grams. Rats were divided into 5 treatment groups. Group I was normal rats group, group II was hypercholesterol rats without treatment, group III was hypercholesterol rats with pulp fruit flour diet, group IV was hypercholesterol rats with whole fruit flour diet, group V was hypercholesterol rats with peel fruit flour diet. Each diet contained 100 mg / kgBB. Statistical analysis showed that a diet of pulp fruit flour and whole fruit flour can reduce levels of total cholesterol, triglycerides, and LDL significantly (p<0.05). Digesta characteristics differed among the treatment group and the hypercholesterolemia group without treatment (p <0.05). The whole fruit flour has ability to lower cholesterol better than pulp fruit flour, whereas, peel fruit flour has no hypocholesterolemic effects. Keywords: hypercholesterolemia, resistant starch, Uter Banana Flou Abstrak Kolesterol dibutuhkan oleh tubuh dalam jumlah tertentu agar tidak membahayakan kesehatan.

AbstractSprague-Dawley albino male rats (25) were divided into five groups consisting of five rats each. Polymer (polylactic acid) impregnated ALCAP capsules filled with 40 mg DFMO were implanted subcutaneously (SC) or intraperitoneally (IP) in Group I and II rats respectively. Rats in Group III were implanted with empty polymer impregnated ALCAP capsules (ALCAP control). Group IV rats were administered orally 3% DFMO in drinking water. Rats in Group V served as controls. Blood samples were collected every week for nine weeks via the tail artery. The concentration of DFNO in the plasma was determined. Data obtained showed that the levels of DFMO in the serum of rats in groups I, I, and IV were 64.71 ±4.08. 219.18 ± 14.48, 16.71 ± 5.21 ug ml−1, respectively at the end of nine weeks. Body weights of the controls and DFMO treated rats were not significantly different (p<0.05). The diarrhea often noted in rats treated orally with DFHO was not observed in rats implanted with ALCAP or ALCAP capsules filled with DFMO. The results of this study suggest that: (1) polymer impregnated ALCAP ceramic implants can be used to deliver DFMO in vivo in a sustained manner for long durations of time, and (2) a ceramic system can be designed to deliver DFNO and drugs such as DFMO in a sustained manner over long durations of time in humans.

Unilateral ureteral obstruction can occur in all animals and it is located proximal, medial and distal. Obstruction causes abnormalities in ipsilateral ureters in the form of hydrouterers. The aim of this study was to detect hydroureters in post-unilateral medial and distal ureteric rats using a 10 MHz ultrasonography frequency. Thirty-six female Sprague Dawley rats aged 3 months were divided into 3 treatment groups. Each group consisted of 12 individuals. Group I as a control received laparotomy treatment. Group II laparotomy with medial right-hand ureteral ligation and group III with right distal ureteral ligation. Three rats taken randomly from each group at weeks 1, 2, 3 and 4 post-ligation is then performed ultrasonography. The results of ultrasonography were analyzed descriptively, comparatively but ureteral diameter were analyzed using statistical of 3x4 factorial patterns. Ultrasound examination showed that ligation in one ureter caused rat undergoing unilateral ureteral obstruction and hidroureter. The diameter of the ureter with a hydroureter has increased from the 1st to 4th week. The increase occurs because the urine in the lumen cannot be excreted. The contralateral ureter remains normal and cannot be observed. The conclusion of the study is that hydroureter in rats can be detected using the frequency of 10 MHz ultrasonography which is characterized by anekoic tubular formation posterior to the right kidney. The unilateral ureteral obstruction has no effect on the contralateral ureter because it is still able to compensate for the performance of the ipsilateral ureter that has a hydroureter. The difference in the location of ligation and time of examination affect the increase in ipsilateral ureteral diameter.

AbstractObjectives:To determine the effect of royal jelly (RJ) on the oxidant-antioxidant balance in rats with N-methyl-N-nitrosourea (MNU) induced breast cancer and to compare this with the chemotherapeutic agent paclitaxel.Material and methods:Fifty-six female Sprague Dawley rats were divided into five groups. Except control group (n=8, Group I) others received MNU (50 mg/kg, a single dose, i.p.) to develop breast cancer: Group II (n=8) untreated, Group III (n=7) treated with paclitaxel (15 mg/kg/week, 3 times, i.p.), Group IV (n=7) with RJ (by oral gavage, 100 mg/kg/day, for 30 days), and Group V (n=7), with paclitaxel+RJ. At the end of 30 days, histopathological and biochemical parameters were evaluated in breast tissues.Results:Levels of protein carbonyl (PC) and 8-hydroxy-deoxyguanosine (8-OHdG) were higher in Group V than in Group II while malondialdehyde (MDA) levels were lower in groups IV and V compared to Group II (p<0.05). Levels of catalase (CAT) in Group V and glutathione (GSH) in Group III were higher than Group II (p<0.05). Glutathione peroxidase (GPx) and superoxide dismutase (SOD) levels did not significantly different. Decreasing effect of RJ on CA15-3 levels was relevant to histopathological results.Conclusion:Although RJ (with or without paclitaxel) had increasing effect of antioxidant status it was insufficient to reduce oxidative stress in breast cancer.

Objective. To investigate the influence of reproduction of different thickness and palatal rugae materials on complete dentures speech using Computerized Speech Lab (CSL) (spectrogram).Materials and Methods. Three completely edentulous male patients (aged 50–60 years) were selected for reading a paragraph. Twelve upper dentures were constructed, four for each patient. The patients’ speech groups were divided into five groups, Group I: patients without dentures; Group II: patients rehabilitated with conventional acrylic dentures; Group III: patients with conventional acrylic dentures with rugae reproduction; Group IV: patients with dentures with metallic framework of minimal thickness and direct ragged metallic palatal surface at rugae area; Group V: patients with dentures with palatal rugae constructed from resilient acrylic resin material with thickness less than conventional denture. Speech samples were recorded after insertion of each denture for groups using Computerized Speech Lab (CSL) (spectrogram). The sounds selected were lingopalatal /s/z/sh/t/d/ and /l/.Results. Group III produced high mean significant difference with /sh/t/ sound. For Group IV, the difference was noticed with /s/z/sh/t/ and /d/ sounds, while for Group V the difference was shown with /z/l/ sound (P<0.05).Conclusion. It is recommended to reproduce the rugae area in complete denture because the phonetic quality of complete denture with rugae is superior to the conventional denture.
