Abstract: This study was aimed to prove that administration of 10% redfruit extract cream could prevent the increase of skin melanin in guinea pig exposed to UVB and to compare this effect with 4% hydroquinone cream. This was a true experimental study using post test only control group design. Subjects were devided into three groups; each of 10 guinea pigs. Group 1, the control group, was exposed to UVB and applied with basic cream. Group 2 was exposed to UVB and applied with 4% hydroquinone cream. Group 3 was exposed to UVB and applied with 10% redfruit extract cream. The total dose of UVB was 390 mJ/cm2 given for 2 weeks. The amount of melanin was calculated using the percentage of the pixel area of melanin and was compared with the pixel areas of all epidermal tissues. The results showed that the highest percentage of melanin area was in group 1 (19.78%±3.79%). The percentage of melanin area in group 3 was 1.25%±0.76% meanwhile in group 2 was 0.85%±0.37%. There were signi-ficant differences in melanin percentage between the control group and group 2 as well as group 3 (P <0.05). There was no significant difference in melanin percentage between group 2 and group 3 (P >0.05). Conclusion: The 10% redfruit extract cream could prevent the increase of skin melanin in guinea pig exposed to UVB as effectively as the 4% hydroquinone cream.Keywords: redfruit extract cream, melanin, UVBAbstrak: Penelitian ini bertujuan untuk membuktikan efek pemberian krim ekstrak buah merah 10% dalam mencegah peningkatan jumlah melanin kulit marmut yang dipapar sinar UVB dan perbandingannya dengan krim hidrokuinon 4%.

Abstract: The coffee beans composed of the compound caffeine, palmitic acid, linoleic acid and acid stearic. The content of caffeine in coffee can improve spermatozoa motility that are not motile by inhibiting cyclic nucleotide phosphodiesterase and affects the intracellular levels of cyclic AMP. Spermatozoa quality can be affected by various factors such as stress. In nocturnal animals, dark periode becomes a signal to do activity by suprachiasmatic nucleus. The change in activity of the nocturnal animals from initial condition in the dark then exposed to light can leads to stress. This study was aimed to determine the effect of coffee on the spermatozoa quality of wistar rats which had been exposed to stress. This was an experimental analytical study with a post-test only control group design. The study was conducted for 50 days from September to November 2016. The sample consisted of 9 rats divided into three groups: a control group (P0) is given only exposure to stress in the form of light, the treatment group 1 (P1) is given exposure to stress in the light form and liquid coffee 1 ml / kg and the treatment group 2 (P2) is given exposure to stress in the light form and coffee extracts. The results showed that there were significant differences in the concentration and motility treatment group 1 (P1) to the control group (P0) which is p <0.05 and significant differences in sperm motility treatment group 2 (P2) to the control group (P0) which is p <0.05. Conclusion: Coffee administration could improve the quality of spermatozoa of wistar rats exposed to stress.Keywords: stress, coffee, quality of spermatozoa. Abstrak: Biji kopi tersusun dari senyawa kafein, asam palmatik, asam linoleat dan asam stearik.

The leaf, stem and bark of Eucalyptus citriodora are combined for use in the treatment of malaria in Anyigba, North Central, Nigeria. However, no scientific investigations have been carried out to know the effect of this plant on biochemical parameters of experimental mice. Thus, this study evaluated the biochemical parameters of mice infected with Plasmodium berghei after the administration of ethanolic leaf extract of E citriodora. Twenty-four (24) mice of body weights between 18-25 g were grouped into six groups. Group 1, infected but not treated (negative control), group 2, infected and administered with 0.2 mg/kg of chloroquine (positive control), group 3, not infected, but administered with 0.2 ml of normal saline (normal control), while the remaining three (3) groups were infected and treated with 200, 400 and 800 mg/kg body weight of the extract respectfully. The pack cell volume (PCV) was assessed before and after infection and treatment using standard procedure. The mice were sacrificed on the sixth day and blood samples were collected for biochemical analysis using standard methods. The PCV in mice of all groups decrease significantly (p<0.05), except group 3 (normal control) that increased. The alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin level was higher in negative control (group 1) than in all other groups studied, but it was higher in the group treated with 200 mg/kg bd wt of the extract than in the positive control and the groups treated with 400 and 800 mg/kg body weight of the extract. A similar trend was observed in the levels of cholesterol, triglycerides, high density lipolipid (HDL) and low density lipolipid (LDL). The level of creatinine, blood urea and nitrogen were observed to be low in groups 1 and 2, compared to other groups. This study revealed that E. citriodora ethanolic leaf extract does not exact toxic effect on the internal organs like liver, kidney and heart.

Spinal anesthesia was typically used for elective surgery and was associated with the incidence of hypotension and bradycardia due to sympathetic block. Bezold-Jarisch reflex (BJR) is a reflex that contributes to cause hypotension and bradycardia mediated by serotonin receptors (5-HT3). Ondansetron, a 5-HT3 receptor antagonist, is assumed to inhibit the effect of serotonin and BJR. To assess the effectiveness of ondansetron in preventing hypotension and bradycardia after spinal anesthesia. This study was an experimental study with a "posttest with control group" design conducted at Haji Adam Malik General Hospital and USU Hospital in February 2020 to June 2020. Seventy study subjects who underwent lower abdominal, gynecology, lower extremities under spinal anesthesia were selected by consecutive sampling and were divided into 2 groups. Group 1 received 4 mg ondansetron, while group 2 received 2 cc normal saline, both interventions were given 30 minutes before spinal anesthesia Baseline and minimum mean arterial pressure were higher in the ondansetron group at 97.07 ± 5.09 mmHg and 85.20 ± 6.48 mmHg compared to the control group (p-value <0.05). Hypotension was more common in the control group (51.43%) than in ondansetron group (20%) (p-value <0.05). The mean baseline and minimum heart rate were higher in the ondansetron group at 81,09 ± 9,62 bpm and 79.7 ± 8.75 bpm compared to the control group (p<0.05). The incidence of bradycardia was more common in the control group (17.1%) compared to the ondansetron group (2.9%) (pvalue <0.05). Ondansetron 4 mg, given intravenously, is effective in lowering the incidence of hypotension and bradycardia under spinal anesthesia
