Abstract

Chronic stress can have an adverse effect on behavior changes and damage to the pyramidal neurons of the brain. Pyramidal neurons of the brain play an important role in awareness, decision making, cognitive function, spatial memory formation and working memory. The effects of chlorogenic acid (CGA) found in arabica coffee can affect the improvement of cognitive function, working memory, and histology of brain pyramidal neurons. The content of chlorogenic acid (CGA) in coffee has active compounds that can maintain the number of brain pyramidal neurons due to stress. The aim of this study was to determine the effect of arabica coffee extract on the average number of brain pyramidal neurons exposed to UCS stress. The research method used was a post-test experimental study with controlled group design. A total of 24 adult zebrafish (3 months old) were divided into 4 groups. Four groups (KN, KP, K25, K50) were acclimatized (1 week) first, for groups K25 and K50 were given arabica coffee extract as much as 25mg / dl and 50 mg / dl for 4 days before inducing unpredictable chronic stress (UCS). The results of the study proved that the extra ethanol group of arabica coffee at a dose of 50 mg / dl could maintain the number of pyramidal neurons in zebrafish treated with modified UCS stress (P <0.05). In conclusion, giving ethanol extract of arabica coffee at a dose of 50 mg / dl has a neuroprotectant effect on zebrafish exposed to UCS stress.

Abstract

Astrocytes of hippocampus contribute in the learning performance. Entrainment of gamma wavescan improve learning performance by improving the neurons to astrocytes communication. Theaim of this study was to evaluate the effect of binaural entrainment of 2000-2040 Hz and 2000-2090 Hz on Glial Fibrillary Acidic Protein (GFAP) expression in astrocytes of the CA1 region ofrat hippocampus during operant learning conditions. Twenty male Wistar rats aged 4-6 weekswith body weight 100-150 g were devided into 4 groups. Group I was given binaural soundsentrainment at 2000-2040 Hz without learning test. Group II was given entrainment as performedin Group I followed by a learning test. Group III was given binaural sounds entrainment at 2000-2090 followed by a learning test. Group IV was not given entrainment nor learning test. Theentrainment was performed for 30 minutes everyday for 12 days and the learning test wasperformed for 10 minutes everyday for 12 days. The GFAP expression was examinedimminohistochemically. Astrocytes processes and astrocytes histoscore were also calculated.The results showed that the number of the GFAP-positive astrocytes in Group I (70.96 ± 4.86),II (69.76±3.07) and III (63.10±5.85) were significantly higher than Control (47.33±1.33)(p<0.05). The number of the processes astrocytes in Group I (47.64 ± 3.87), II (60.66±2.07)and III (54.17±6.38) was significantly higher than Control (30.87±2.69) (p<0.05). Moreover,the number of the processes astrocytes in Group II was significantly higher than Group I (p=0.016).The astrocytes histoscore index in the Group II (115.58±14.13) and III (78.32±22.23) weresignificantly higher than Group I (28.79 ± 9.61) and Control (16.05±1.64) (p<0.05). Inconclusion, the binaural entrainment of 2000-2040 Hz and 2000-2090 Hz increase GFAP expressionof astrocytes in Cornu Ammonus 1 (CA1) region of rat hippocampus during operant learningconditioning.

Abstract

Ketamine and ketamine-xylazine are often used as anesthetic drugs in animal models of ischemia. However, their neuroprotective and neurotoxic effects in ischemic animal models that have undergone tBCCAO are still under debate. The protein p53 is a pro-apoptotic factor involved in the cellular mechanism of ischemia. The interaction between death-associated protein kinase 1 (DAPK 1) and p53 is fundamental in determining whether cells experience necrosis or apoptosis in an ischemic stroke. This study was purposed to identify the presence or absence of differences between the p53 expressions in the brains of tBCCAO-induced ischemic rat models after the administration of ketamine and ketamine-xylazine. It employed a post-test control group design with four groups of adult male Wistar rats as the subject: (1) sham group operated with ketamine, (2) sham group operated with ketamine-xylazine, (3) models of tBCCAO-induced ischemia with ketamine, and (4) models of tBCCAO-induced ischemia with ketamine-xylazine. Ketamine was administered at the dose of 75mg/kg BW, while xylazine was at 8 mg/kg BW. The expression of p53 in rat brains was assessed by semi-quantification, specifically IHC staining with anti-p53 antibodies. P53 expression appeared as brownish stains in the cytoplasm of forebrain pyramidal neurons, and in this study, it was measured using the Allred score. The ANOVA test yielded a p-value of >0.05, implying the absence of difference between the p53 expressions in the brains of tBCCAO-induced ischemic rat models receiving ketamine and ketamine-xylazine.

Abstract

Formaline solvent is widely used in life, example as a preservative cadaver in anatomy laboratory. Forma line solvent can evaporate easily, in the form of gas it should be react with mucous layer quickly, especially at respiratory tract. In human body, it is oxidated become formic acid, especially in the cells of liver and red blood. In many earlier researches, the short-term exposure caused irritation to the local mucous surface of eyes, nose and up respiratory tract. However, the long term exposure caused tumor growth in the rat nose, pulmonary t issue damage and asthma reactions in sensitive individuals. The aim of the study is to measure forma line gas concentration and comparing the result with Thresold Limit Value (TLV) that safety for health. The research is nonexsperimental study with associative analysis. The research objects were practice space, storage cadaver space and lobby of Anatomy Laboratory. The research subjects were divided into 3 phases of measurement, phase I is measurement in the athmosphere (control), phase II is measurement in practice space laboratory during activities and phase Ill is measurement in practice space laboratory with no activities. Formaline gas concentration in practice space Anatomy Laboratory is under the TLV (TLV: 0.3 ppm) with no activities. Duringactivities, it is over the TLV: in preparation space 0,99569 ppm and practise space 0,37804 ppm. Formaline gas concentration in practice space during activities is over the TLV. It is a risk to cause some health disorders, especially to user and staff of the laboratory. It need good planning of practise programs and design of anatomy laboratory based on safety.

Abstract

Background: Brain-derived neurotrophic factor (BDNF) is a neurotrophin secreted by dendrite, which plays a role in differentiation, maturation, neuroplasticity, learning, and memory, which the expression decreases under stress conditions. Propolis contains chrysin which has antioxidant and neuroprotectant effects.Objective: This study aimed to examine the effect of propolis on BDNF expression in the hippocampus of stress-induced rats.Methods: Experimental study using posttest only control group design. The subjects were 25 male Spraque-Dawley rats (Rattus norvegicus), four months old, weighing 200-300 grams. Rats were randomly divided into five groups: group N, did not receive any treatment; group K, received stress treatment; groups P1, P2, and P3, received stress treatment and followed by administered propolis at doses of 100, 150, and 200 mg/kg/day. Social isolation stress was carried out by putting one rat in one cage. Oral propolis administration used oral gavage. In the end, the rats were terminated and brain tissue was collected. Immunohistochemical staining using anti-BDNF antibodies was performed to make histological slides. Observations were made with a light microscope with 1000x magnification in the CA1 area of the hippocampus.Results: There is a significant difference in BDNF expression in the CA1 area of the hippocampus in all groups (p=0.000). The highest BDNF expression was in the P3 group and the lowest in group K.Conclusion: There is an effect of propolis on BDNF expression in the hippocampus of the stress-induced rat. Propolis dose of 100 mg/kgBW/day has increased BDNF expression.
