Abstract

Objective:  We aimed to investigate whether cold stress increased plasma and joint IL-1β and whether vitamin C quenched ROS and reduced increased IL-1β. Secondly whether there is any correlation between plasma and joint IL-1βlevel.Material and methods:  Male adjuvant arthritic rats (age=10-12 weeks; n=8/group) were exposed to cold stress (5oC for 15 minutes/day for 7 days) with/without vitamin C (50 mg/day orally) and then kept for 14 days. The control group did not receive either cold exposure or vitamin C. Plasma IL-1βlevel was measured using indirect ELISA and joint IL-1β was measured using imunohistochemistry before treatment, day 0, 7, 14 after treatment.Result:  Cold stress significantly increased plasma IL-1β level directly after cold stress (p=0.025), 14 days after cold stress (p=0.002). Cold stress significantly increased percentage area positive of joint IL-1β day 7 (p=0.001), day 14 (p=0.001). Compared to controls vitamin C significantly reduced plasma and joint IL-1β directly after cold stress, day 7, 14 after cold stress (p< 0.05). No significant correlation between plasma and joint IL-1β in all groups (p>0.05).Conclusion:  Cold stress increased plasma and joint IL-1β and vitamin C reduced increased IL-1β  possibly by reducing ROS production and NF-kB activation.

Abstract

Objective:  So this study is trying to analyze the potency of Javanesse Gending as the therapeutic music. It is a further exploration of the finding state that the Gending Tejanatha has the spectral characteristic similarity with The Magic Flute of Mozart. Material and methods: The study was done by analyze the audio characteristics patterns of five Javanesse Gending (JG) compare with the  five classical music (CM) of Mozart and Beethoven. The audio characteristics were obtained from the sound analyzer program. The results were in form of spectral graphics. The parameters include spectral envelope, sound intensity and frequency.Result:  JG and CM have different pattern for the left and the right audio. This indicate difference stimulus for the neural, that will appear as cross references for primary audiory area. The frequencies of JG is higher than CM. The frequency and envelope indicate the variation of emotion that will be induced. It represent the sound colour (timbre). The JG timbre is determined by the material of the instruments, used to made from copper or iron. This material does infuence the emotional responses, especially to the player (pengrawit). The influence of the timbre, not as intens as the influence of the musical tempo that relate with the rhythm harmony. In the JG, the musical tempo represent the soul of this music. It is very essential. The tempo changes from the  usual pattern will raise the anxiety.Conclusion: It can be concluded that the JG has the same potency as the CM to be used as therapeutic music. The JG has the higher potency to influence emotional state than the CM due to its envelope profile.

Abstract

Objective: To asses visceral fat profile protein between normal and obesity model rat. Material and Methods: Normal and obesity rat model have been treated with polyphenol from rambutan peel extract for 12 weeks. Rat were divided into 2 major group  based on their weight which normal rat and obesity model rat respectively have average weight 180-200 gram and 360-380 gram. This treatment were divided into minor group which are placebo (without treatment),  treatment with ellagic acid and treatment with polyphenol (dosage 15 mg/kg body weight; 30 mg/kg body weight and 60 mg/kg body weight. Rat were sacrificed after 12 weeks treatment to asses visceral fat profile protein and continue with running SDS PAGE12,5 %. Protein molecular weight sample were calculated with regression analysis between marker protein mobility and logarithm from marker. Band protein analysis were analyze qualitative with SDS PAGE meanwhile quantitative analysis with Gel Doc (Bio Rad). Density band protein were analyze were using Quantity One software and confirmed with Western Blotting.Result: Protein profile characteristic normal rat and obesity-model rat were in range between117-20 k Da. The amount of band protein were found in normal rat were less than the amount of protein at obesity-model rat. Conclusion: There were difference molecular weight at protein density 57 k Da for obesity model rat which has been treated with rambutan peel extract.

Abstract

Objective:  This descriptive study aims to describe the cytogenetic profile of students with mental retardation disorders on special school in Banjarmasin conducted since 2012-2013.Material and methods:  Cytogenetic profile described based the existence of free trisomy 21, trisomy 21 with translocation, mosaic trisomy 21 and trisomy 21 partially or in the form of numeric aberration and structure of chromosomal abnormalities such as fragile X, specific deletions of chromosomal segments or the presence of a ring chromosome forms.Result:  The results obtained from the study of 22 students with physical signs of mild to severe syndromic mental retardation. The results of cytogenetic examination showed most of the sample (77.78%) with free trisomy 21 (karyotype 47, XX, + 21 or 47, XX, + 21) or a classic type of Down syndrome, 1 sample with mosaic karyotype: 46, XY (1%) / 47, XY, + 21, 1 sample with structural abnormalities of chromosomes 22 (karyotype: 46, XY, ring 22) and 2 samples with normal karyotype (karyotype: 46, XY or 46, XX).Conclusion:  Cytogenetic profile of students with syndromic mental retardation on special school in Banjarmasin are free trisomy 21, mosaic trisomy 21, structure aberration (ring chromosome 22), and a normal karyotype.

Abstract

Objective: To prove that the lecithin is administered orally has hepatoprotective effect on white male rats given CCl4 intraperitoneally.Material and Methods: 45 male Wistar rats, aged 12 weeks were randomly divided into five groups. Group I, given solvent CMC - Na 0.25% dose of 0.01 ml/g bw, and were given olive oil dose of 1 ml/kg bw, intraperitoneal injection. Group II, given solvent CMC - Na 0.25% dose of 0.01 ml/g bw, and given CCl4 dose of 1 ml/kg bw,dissolved in olive oil by intraperitoneal injection. Group III, IV and V respectively given dose lecithin 90/180/360 mg/ kg bw,dissolved with 0.25% CMC-Na, and  given CCl4 dose of 1 ml/kg bw dissolved in olive oil at a ratio of 1: 1, by intraperitoneal injection. On day 10, 24 hours after administration of CCl4 and olive oil , all the rats dissected, after first anesthetized with ether by inhalation. Then the blood taken from the heart to examine the level of AST and ALT in serum and hepar were taken for  histopathological examination.Results: Giving  lecithin 90/180/360 mg/kg bw were accompanied CCl4 1 ml / kg body weight (group III, IV, and V), shown to reduce levels of SGOT in serum compared with the group that received only CCl4 and giving lecithin 90/180/360 mg/ kg bw with CCl4 1 ml/kg bw  (group III, IV, and V) is proven to reduce ALT levels compared with the group that received only CCl4. On histopathological examination of liver cells proves that lecithin dose 90 / 180/360 mg/kg bw with CCl4 1 ml/kg bw is proven to reduce the amount of cell necrosis than the group that only received CCl4.Conclusion: Lecithin has a protective effect against the liver function.
