BACKGROUND<br />Sleep deprivation is a significant problem among adult men and is considered as a risk factor for several diseases. Paradoxical sleep deprivation (PSD) induces Leydig cell apoptosis through elevation of corticosterone, with testicular malondialdehyde (MDA) and Leydig cell caspase-3 expression as parameters. The aim of this study was to observe testicular MDA level and caspase-3 expression treated with paradoxical sleep deprivation (PSD), immobilization, and footshock stress and to determine the stress model with a significant effect in white male rats (Rattus norvegicus) . <br /><br />METHODS<br />This experimental randomized study of posttest only with control group design was conducted on 24 white male Wistar strain rats, randomly allocated into four treatment groups, i.e. control (K1) without any stress treatment, PSD (KII), immobilization (KIII), and footshock stress (KIV). Treatments were given for 25 days to produce chronic stress. Testicular MDA concentration was examined by the ELISA method while caspase-3 was examined by the TUNEL method.<br /><br />RESULTS<br />Mean testicular MDA concentration with one-way ANOVA test showed differences in means between the groups (p=0.000) and post hoc Tukey-HSD test showed significant results between PSD stress group versus control, immobilization and footshock stress groups. One-way ANOVA test showed a significant difference in caspase-3 expression in at least two treatment groups (p=0.008) and post-hoc Tuckey-LSD test showed significant differences between controls and all stress groups. <br /><br />CONCLUSION<br />Sleep deprivation is a type of stress inducing changes in testicular MDA concentration and caspase-3 expression in male rat testes.

Air fresheners are products that contain chemicals aimed at reducing unpleasant odours in confined spaces. The use of synthetic air fresheners turns out to harm health because some of their leased Volatile Organic Compounds are classified as toxic compounds and are carcinogens. Air freshener enters the body through the inhalation process in the respiratory system. Modern air fresheners are available in liquid (aerosol) and gel forms. Air fresheners contain addictive substances and solvents such as 1,4-dichlorobenzene which can affect pulmonary function. The purpose of this study is to know the effect of exposure to liquid air freshener on the histology of bronchi of mice (Mus musculus). This study used 20 male mice (Mus musculus) consisting of 4 treatments with 5 replications. The research design is true experimental in the form of a post-test only control group with Completely Randomized Design (CRD). The post-test was done by observing the histological picture of the mice's bronchi after exposure to liquid air freshener given 3x/day for a period of P1 = 2 weeks, P2 = 4 weeks and P3 = 6 weeks. Quantitative data on bronchial histology was tested using the One Way ANOVA statistical test followed by the Post Hoc Tukey test. The results of the study found changes in the histology of the bronchi, thickening of the epithelial tissue of mice. Analysis of comparative data between the control and treatment groups statistically obtained p = 0.010 <0.05, meaning that there was a significant effect and change in the bronchial tubes exposed to liquid air freshener. Histologically there were differences in histology between the control and treatment groups. It was concluded that liquid air freshener had a significant effect on the histological picture of the mice's bronchi.

Introduction: Doxorubicin (DOX), a well-known chemotherapeutic drug, has been reported to induce numerous toxic side effects including renal toxicity. This preliminary study was designed to investigate the ameliorative effects of methanolic leaf extract of Clerodendrum volubile (MECV) against DOX-induced nephrotoxicity in rats. Methods: Thirty male rats were divided into five groups; (a) Control group: rats were given 0.9% NaCl as vehicle, (b) DOX group: a single dose of DOX (25 mg/kg; i.p.) was administered and the rats were sacrificed 4 days after DOX injection, (c-e) Methanolic extract of C. volubile (MECV)-treated DOX groups: rats were given MECV (at the doses of 125, 250 and 500 mg/kg/d), respectively for 12 consecutive days, 8 days before and 4 days after the DOX administration. Results: DOX injection caused a significant increase (P<0.05) in serum creatinine and urea levels. The levels of renal antioxidant parameters: glutathione peroxidase, superoxide dismutase (SOD), catalase (CAT) and reduced glutathione were significantly (P<0.05) decreased in DOX-intoxicated rats with concomitant elevation of malondialdehyde level. Pretreatment with MECV restored antioxidant status, attenuated oxidative stress and improved kidney function markers. Pre-treatment with MECVprotected renal tissues against DOX-induced nephrotoxicity. Conclusion: The ameliorative effects of C. volubile leaves on these renal biochemical parameters may be via its antioxidant action and may serve as a novel combination agent with DOX to limit its renal damage.

Abstract: Elastomeric ligature is used to fasten orthodontic wires with brackets and can be stretched 1-3 mm as a simulation of bracket in the oral cavity. Its elastic force could decrease caused by salivary pH and water absorption of the elastomeric ligature. Consuming carbonated drinks causes the oral cavity to become acidic which increases the loss of elastic force in the elastomeric ligature with length of stretch variations. This study was aimed to determine the effect of immersion in carbonated drinks on the elastic force of the elastomeric ligature with length of stretch variations. This was an experimental laboratory study with a post-test only control group design. There were a total of 24 samples of American Orthodontic brand elastomeric ligature with royal blue color divided into six groups, consisting of three control groups immersed in artificial saliva, and three treatment groups immersed in carbonated drinks. Each control group and treatment group were given three variations of stretch length, as follows: 1, 2, and 3 mm. The calculation of the elastic force on the elastomeric ligature was performed by using the Universal Testing Machine. Data were analyzed by using the One Way Anova test and LSD post hoc test (p <0.05). The One Way Anova test showed a significant difference in the 1, 2, and 3 mm length of stretch variations for treatment groups. In conclusion, carbonated drinks affect the elastic force of elastomeric ligature with length of stretch variations.Keywords: elastomeric ligature; carbonated drinks; length of stretch variations Abstrak: Elastomerik ligatur adalah alat yang digunakan untuk mengikatkan kawat ortodonti dengan braket, dapat diregangkan 1-3 mm sebagai simulasi braket dalam rongga mulut.

Background: With regard to tobacco and alcohol addiction, involvement of NMDA receptors and glutamate as neurotransmitter has been highlighted. Few indirect evidences support possible de-addiction potential of zinc being mediated through their interaction with nicotinic and NMDA receptors. The objectives of the present study were planned to analyze the alcohol de-addiction potential of oral zinc sulfate as a monotherapy and as a supplement to topiramate, in male wistar albino rats.Methods: Male wistar albino rats were exposed to ‘two-bottle free choice’ model of voluntary ethanol consumption, wherein each animal had access to water and 10% v/v ethyl alcohol in two separate bottles. Thirty male rats divided into five groups, each containing six rats were treated as control group, receiving 1ml/kg/d distilled water orally; zinc sulfate group receiving 18mg/kg/d of elemental zinc orally; topiramate group receiving topiramate 5mg/kg/d, orally and Topiaramate plus Zinc sulfate group receiving both zinc sulfate (18mg/kg/d) and topiramate (5mg/kg/d) orally for two weeks.Results: There were no significant differences with regard to all the three parameters in two-way ANOVA. However, there were significant differences with regard to amount of alcohol and water consumed but not API, in all the treatment groups in post-hoc test.Conclusions: It is unclear on to the alcohol de-addiction potential of zinc as monotherapy and combination therapy with topiramate.

Abstract Background: Optimizing thrombolytic therapy is vital for improving stroke outcomes. We aimed to develop standardized thrombolysis conditions to evaluate the efficacy of tenecteplase (TNK) compared to the current gold standard rt-PA (alteplase), with and without additional ultrasound treatment. We also wanted to introduce a new analytical approach to quantify fibrin fiber density in transmission electron microscopy (TEM). Methods: In vitro clots that are similar to ex vivo clots concerning their histological condition and their durability were generated from whole blood. For five treatment groups we compared relative clot weight loss (each n=60) and fibrin fiber density in TEM (each n=5). The control group (A) was treated only with plasma. Two groups were designated for each rt-PA (B+C) and TNK (D+E). Groups C and E were additionally treated with ultrasound. Dosages were 50µg/ml for rt-PA and 30µg/ml for TNK. Results were evaluated by using analyses of variance (ANOVA) and post-hoc t-tests. Results: Weight loss was increased significantly for all groups compared to the control group. Both TNK groups showed significantly increased weight loss compared to their counterpart rt-PA group (p≤0.001). For TEM only group D showed significantly decreased fibrin fiber density (p<0.05) compared to both rt-PA groups. Ultrasound did not significantly increase dissolution of clots with either method (best p=0.16). Conclusions: Tenecteplase dissolved clots more effectively than rt-PA with and without ultrasound. A higher sample size could provide more convincing results for TEM.
