Caffeine in coffee is suspected to decrease the bone mineral density and increase the risk factor of osteoporosis, however the contents of coffee is not only caffeine. Considering the great number of people consuming coffee daily, therefore, the study is conducted to investigate the effect of robusta coffee consumption on the femoral bone strength in male wistar rats. Thirty male wistar rats were subjected for the study. They were divided into three groups, i.e control group (K) without robusta coffee consumption, treatment group 1 (P1) with robusta coffee consumption of 0,9 mg/gBW, and treatment group 2 (P2) with robusta coffee consumption of 2,7 mg/gBW. After 21 days, the rats were terminated and the right and the left femurs were collected for force bone test. The force bone test of P1 and P2 group demonstrated weaker bones than K group, and there was no difference effect of P1 group compared to P2 group on the femoral bone strength in male wistar rats. It can be concluded that robusta coffee consumption has negative effect on the bone strenght and hence causing bones more fragile, and there was no difference on effect of 0,9 mg/g BW compared to 2,7 mg/g BW.

This study aims to determine the morphology of Leydig cells in hyperlipidemic wistar rats after having administered with sembung (Blumea balsamifera) extract orally. This study utilised a randomized post-test only control group design. The sample in this study were 16 adult male wistar rats (Rattus novergicus) aged 3-4 months with a body weight of 150-200 grams, which were equally and randomly divided into two groups, namely control group (hyperlipidaemia and sterile aquadest) and treatment group (hyperlipidaemia and sembung leaf extract). Hyperlipidaemia was induced with lard administration for 50 days. Data were analysed statistically using the Independent t-test. The results showed that the number of Leydig cells in the treatment group was higher than the control group with 68.13 ± 1.89 and 55.63 ± 1.92 cells respectively (P <0.05). In addition, the mean Leydig cell core diameter of the control group, 5.00 ± 0.34 µm, was smaller compared to the treatment group which was 5.80 ± 0.20 µm (P <0.05). It can be inferred that sembung leaf extract provides a protective effect against damage to Leydig cells due to hyperlipidaemia.

ABSTRACT Non-alcoholic fatty liver can be triggered by used cooking oil consumption due to the formation of free radicals and the accumulation of fatty acids in the body. Astaxanthin is a powerful antioxidant that may be able to inhibit the pathogenesis of fatty liver. This study aims to determine the effect of astaxanthin in inhibiting fatty liver (steatosis) and levels of Gamma-Glutamyltransferase (GGT) in male Wistar rats given used cooking oil. An experimental study with Post-test Only Control Group Design was conducted on 36 male Wistar rats aged 3.5-4 months with an approximate bodyweight of 200-210 grams divided randomly into 2 groups. The control group was given 0.42 ml of used cooking oil + 0.5 ml of distilled water, and the treatment group was given 0.42 ml of used cooking oil + 0.2 mg of astaxanthin each day for 14 days. On day 15, blood tests and hepatic histopathology were performed to check  GGT serum levels and steatosis. The comparative test was conducted to compare the results of the control and treatment groups. The results showed that the mean steatosis and GGT levels in the treatment group were significantly lower than the control group. It can be concluded that giving astaxanthin can inhibit fatty liver (steatosis) and increase GGT serum levels in male Wistar rats given used cooking oil.   Keywords: Astaxanthin, Fatty liver, Gamma-glutamyltransferase, Used cooking oil

Introduction: Diabetes mellitus is a complex and progressive disease which often lead to several debilitating complications that partly caused by by free radicals which can be overcome with antioxidants. Bay leaves contain essential oils, tannins, flavonoids and terpenoids which have considerable antioxidant properties. Therefore, this study aims to determine the effect combination treatment of vildagliptin and bay leaf (Syzygium polyanthum) extract toward pancreatic beta cells density and glycated albumin levels in diabetic male Wistar rats (Rattus norvegicus). Methods: An experimental posttest only control group study was conducted using 36 albino male rats, aged 2-3 months, weighing 180-200 grams. The rats were divided into 2 groups (n= 18) with control group treated with 1.8mg/200g body weight vildagliptin and 2cc placebo (aquabidest) while the treatment group received 1.8mg/200g BW vildagliptin and 250 mg/200g BW bay leaves extract. All treatment lasted for 21 days. Results: The results showed that pancreatic beta cell counts in the treatment group  was significantly higher than the control group  (109.07 ± 20.47 cells/field of view vs 90.87 ± 13.91 cells/field of view; p<0.01). However, the levels of Glycated albumin between two groups were not significantly different (treatment vs control: 17.33 ± 4.51 vs 20.18 ± 4.57; p=0.068). Conclusion: This study suggested that combination treatment of vildagliptin and bay leaf extract increased pancreatic beta cells but did not reduce glycated albumin levels in diabetic male Wistar rats.

Abstract: Excessive physical activity increases the consumption of oxygen which can result in increased levels of reactive oxygen species (ROS) causing oxidative stress characterized by the elevation of F2-isoprostane as a byproduct of lipid peroxidation. Willow (Justicia gendarussa Burm. f.) has an antioxidant activity that is able to inhibit and break the chain reaction of free radicals and prevent lipid peroxidation. This study was aimed to prove that willow leaf extract could inhibit the elevation of F2-isoprostane levels in male Wistar rats (Rattus norvegicus) urin induced by excessive physical training. This was a true experimental study using 16 male Wistar rats (Rattus norvegicus), aged 2-3 months, weighing 180-200 g as subjects. The control group (P0) was treated with a placebo and excessive physical training, and the treatment group (P1) was treated with the willow leaf extract of 200mg/rat/day and excessive physical training. Before and after 14 days of treatment, the urine samples were collected and their levels of F2-isoprostane 8-isoPGF2α were examined by using enzyme immunoassay kit (EIA). The results showed that the mean level of F2-isoprostane in the control group (P0) before treatment (pretest) was 5.20±0.483 ng / mL while in the treatment group (P1) was 5.46±0.655 ng / mL (P > 0.05). On the other hand, after treatment for 7 days (post-test), the mean level of F2-isoprostane in the control group (P0) was 5.34±0.476 ng/mL and in the treatment group (P1) was 3.61±0.389 ng/mL (P < 0.01). Conclusion: The extract of willow (Justicia gendarussa Burm. f.) leaf could inhibit the elevation of F2-isoprostane levels in male Wistar rats (Rattus norvegicus) urin induced by excessive physical training.Keywords: willow leaf, F2-isoprostane, excessive physical trainingAbstrak: Aktivitas fisik berlebih akan meningkatkan komsumsi oksigen yang dapat mengakibatkan peningkatan kadar reactive oxygen species (ROS) sehingga menyebabkan stres oksidatif yang ditandai dengan meningkatnya F2-isoprostan sebagai salah satu produk peroksidasi lipid.

Abstract Introduction: Coffee consumption has proved to be harmful to osseous tissue integrity, thus, diminishing bone resistance. Considering the great number of individuals consuming coffee daily, therefore, the present study aims to demonstrate the effects of coffee on the femoral morphology and biomechanics resistance in Wistar rats. Methods: Twenty male Wistar rats were chosen for the experiment, divided into two groups (n = 10), as to know, CT (control) group, to which was offered water diet ad libitum; and, CF (coffee) group, to which was offered coffee as liquid diet. After 60 days, the animals had their blood analyzed for serum calcium level, they were euthanized and the right femurs were collected for histological procedure and the left ones were isolated for bone measures and mechanical test. Results: CF group animals do not present malnutrition or dehydration. Femur dimensions, trabecular bone width and cortical width analyses shown to be lower for CF group. Material and structural properties of the femurs of CF group animals demonstrate that this group presents weaker bones than those of CT group. Conclusion: The findings in the present study allow us to confirm that coffee consumption interferes negatively on the material and structural bone properties, diminishes trabecular and cortical bone density, and hence making bones more fragile and likely to fractures. So, due to the great number of individuals consuming coffee daily, it is important to reduce this consume on order to prevent bone trauma.
