A single Memory impairment substantially reduces the quality of life in the elderly. It is associated with thealteration of neurotrophic (NT) factors, such as brain-derived neurotrophic factor (BDNF) and glutamatereceptor N-methyl-D-aspartate (NMDA). Exercise is often used to reduce cognitive impairment. Previousstudies show that the benefits of aerobic exercises on such impairments are correlated with increasing BDNFand preventing the production of NMDA. However, some results remain controversial. Thus, the associationbetween exercise and Memory was addressed by examining increases in BDNF and the reduction of NMDAin ageing rats. The study used a randomized, post-test-only controlled group of 30 male one-year-old ageingRattus norvegicus divided into three groups, namely, K0 (control) and K1 and K2 (aerobic swimmingexercise). K1 and K2 animals differed in the frequency of exercise, which is three and four sessions perweek, respectively. Memory was assessed using Y-maze performance. BDNF and NMDA were analyzedusing enzyme-linked immunosorbent assays. A significant improvement in memory function and reductionin the NMDA level were observed in K1 and K2 group rats (p = 0.001; p = 0.041). No significant impact onthe BDNF levels was observed (p = 0.387). Swimming may boost Memory by reducing the NMDA levelbut not by increasing BDNF. Swimming is a promising method for preventing or delaying memory loss indegenerative brain diseases. Further investigation is needed to fully understand underlying mechanisms.

Epidemiology of NSAIDs gastropathy is increasing as increase number of usage. From arthritis to cardiovascular events and cancer prevention, the versatility of NSAIDs is not questioned. However, no dose of NSAIDs is safe. No matter low dose, or single use, NSAIDs will cause gastric damage upto 3-7 days after use. In inflammation and healing process of gastropathy there are various proteins involved, but treatment with COX-2 and SRF are associated with an immediate healing and better quality of gastric mucosa. Cyclea barbata (miers.) has been declared as functional food for preventing and treatment gastropathy yet, its mechanism of actions have not yet clearly discovered. Hence the aim of this study is to analyze the effects of Cyclea barbata (miers.) ethanol extract to COX-2 and SRF in gastric tissue, in time series basis. Laboratory mice was induced with aspirin to produce gastropathy and then treated with Cyclea barbata (miers.) extract for 1, 3, 7, 10 or 14 days. Gastric tissue then harvested and analysed with elisa procedure to determine tissue SRF and COX-2 level. Treatment was proven to increase COX-2 and SRF higher than control group. This concludes one of Cyclea barbata (miers.) mechanism for NSAIDs gastropathy is by increasing tissue COX-2 and SRF.

Budidaya tanaman gaharu (Aquilaria malaccensis Lamrk.) pada lahan perkebunan kelapa sawit merupakan upaya optimalisasi pemanfaatan lahan. Tanaman gaharu adalah jenis tanaman yang menghasilkan produk gaharu, dan jenis ini dikenal dengan nama tanaman karas yang telah dibudidayakan di lahan kebun sawit. Tanaman gaharu pertumbuhannya agak lambat sehingga perlu didukung teknik silvikultur untuk mempercepat pertumbuhannya. Budidaya tanaman gaharu di lahan kelapa sawit dapat ditanam dengan jarak 4 m dari pohon kelapa sawit, dan membutuhkan naungan hingga umur 12 bulan. Teknik silvikultur yang diaplikasikan yaitu arang pelepah kelapa sawit sebanyak 5,0 kg/tanaman, dapat meningkatkan pertumbuhan tinggi 71,0% dan diameter batang 72,2 %. Aplikasi kapur sebanyak 1,0 kg/tanaman dapat meningkatkan pertumbuhan tinggi 42,5 % dan diameter batang 125 %, serta meminimalkan kadar kemasaman tanah dari pH 4,0 meningkat menjadi pH 6,0. Selanjutnya aplikasi 150 g/tanaman pupuk NPK dapat meningkatkan pertumbuhan tinggi 77,6 % dan diameter batang 34,85 %. Diharapkan nilai ekonomi tanaman kehutanan khususnya tanaman penghasil gaharu dapat bersaing dengan komoditi perkebunan, sehingga masyarakat termotivasi membudidayakan tanaman gaharu secara tanaman campuran di lahan kalapa sawit atau di hutan rakyat.

Oxidative stress has been considered as a mechanism involved in the pathogenesis and progression of many diseases such as:hypercholesterolemia and atherosclerosis. The objective of this current study was to know the potential antioxidant role of ethanol andethyl acetate extract of reeds (Imperata cylindrica) by investigation in rats fed with a high-cholesterol diet. Imperata cylindrica is richin antioxidants and has a cholesterol-reducing effect. A group of twenty four male albino Wistar rats was divided into four subgroups: anormal diet group (K0), a high-cholesterol diet group (K1), the same diet with ethanol extract of Imperata cylindrica group (K2), and thesimilar diet with ethyl acetate fraction of Imperata cylindrica group (K3),. After the treatment period, the hepatic antioxidant enzymeactivity (Superoxide dismutase/SOD) was determined. The rats fed on high-cholesterol diet with supplementation exhibited a significantelevation in SOD activity (p<0. 05), 61.6±12.4% inhibition, compared to normal animals 37.44±12.2%. The treated animals withethanol and ethyl acetate extract of Imperata cylindrica showed a significantly reduced the level of SOD activity (p<0.05, 29.90±5.6%as well as a 33.49±7.4% inhibition). The level of SOD activity when restored was closer to that in normal animals, signifying reversalof the oxidative stress. The study results showed that the treatment with Imperata cylindrica positively changed the hepatic antioxidantenzyme activities in high fat-diet rats, and thus had potential hypocholesterolemic and antioxidant effects. Imperata cylindrica couldprotect against oxidative stress linked to atherosclerosis and also decrease the atherogenic index.

Recent studies have shown that Plumbum could disrupt tissue prooxidant/antioxidant balance. The green tea leaves (Camelliasinensis) is an antioxidant scavenger of free radicals and chelator of heavy metals. This study was designed to know and investigate theefficacy of Katekin from green tea leaves malondialdehid (MDA) and superoxide dismutase (SOD) activity in erythrocytes caused by oralPb administration in Wistar rats. Thirty adult male rats were divided into six (6) groups (each groups: 5 rats): K+ group (oral 33.75mg/bw Katekin), K group as a normal control, K- group (oral 15.82 mg/day lead acetate), P1 group (oral 22.5 mg/bw Katekin and 15.82mg/day lead acetate, P2 group (oral 33.75 mg/bw Katekin and 15.82 mg/day lead acetate for), and P3 group (oral 45 mg/bw/Katekinand 15.82 mg/day lead acetate) for 4 weeks. The results showed that Pb exposure induced the raised of MDA levels and decrease SODactivity in erythrocytes of rats. The administration of Katekin from green tea leaves significantly reduced MDA levels and increased SODactivity in Pb exposed erythrocytes of rats. The optimal dose of Katekin from green tea leaves as a scavenger of free radicals and chelatorof heavy metals was 22.5 mg/bw/day (P1). These results indicated that the administration of Katekin from green tea leaves may havean important role in modulating oxidative stress in Pb exposed erythrocytes, but at a higher concentration of Katekin from green tealeaves showed prooxidant activity.
