BACKGROUND: Ceftazidime was known to cause photosensitization reactions. However, how it plays the role remained unclear. In our study, we aim to investigate the photosensitization effect of ceftazidime in erythrocytes via oxidative stress.METHODS: Samples were divided into six different groups: negative control group, positive control group and four experimental groups with 10%, 20%, 30%, and 40% ceftazidime, respectively. The positive control and experimental groups were exposed to ultraviolet (UV)-light for 2 hours. Superoxide radical, malondialdehyde (MDA), carbonyl compounds (CC) and methemoglobin (Met-Hb) levels were then measured.RESULTS: The results showed a significant increased of superoxide radical, MDA, CC and Met-Hb levels in all experimental groups compared to both negative or positive control groups (p< 0.05).CONCLUSION: In conclusion, our study confirmed the role of ceftazidime as a photosensitizer in erythrocytes via the oxidative stress mechanisms.KEYWORDS: ceftazidime, oxidative stress, photosensitizer, photosensitization.

Traditional alcoholic drinks are made traditionally or conventionally and simply packed. One of the traditional alcoholic drinks in Indonesia and commonly consumed is Tuak (Palm wine). Several indigenous communities in Lombok have fermented drinks popularly known as Tuak or Arak. Palm sap which is the basic ingredient in making palm wine containing alcohol. The most common liver diseases due to alcohol abuse include fatty liver, alcoholic hepatitis and liver cirrhosis. Ethanol metabolism in liver cells can cause an increase in the production of free radicals with various mechanisms so that oxidative stress will damage liver tissue. The supply of pineapple can prevent and repair liver damage due to oxidative stress processes, especially those caused by alcohol. Markers of liver damage are SGOT and SGPT enzymes. This research is a true experiment. The total number of experimental animals used was 21 individuals, negative control rats were only given standard feed, positive control rats were given palm wine without pineapple extract and treatment group were given palm wine and pineapple extract. Palm wine and pineapple were given together with standard feed for 14 days and on day 15th, the blood of the rats was taken to check the levels of SGOT and blood SGPT. The results showed the average SGOT enzyme levels in the negative control group 117.85 U / L, in the positive control group 126.14 U / L, and the treatment group 110.71 U / L. ANOVA test shows SGOT levels of white rats have significant differences in the experiments conducted (p <0.05). Examination of SGPT enzyme levels in the negative control group obtained an average yield of 25.42 U / L, positive control 30.42 U / L, and treatment 29.14 U / L. The ANOVA test results of SGPT levels in white rats show significant differences in the experiments conducted (p <0.05).

Diabetes is a metabolic disease that can affect the male reproductive system. The condition of hyperglycemia will increase the production of ROS, causing oxidative stress. Oxidative stress causes microangiopathy, triggers cell apoptosis, interferes with spermatogenesis, thereby affecting the diameter of the seminiferous tubules. Kebar grass contains of flavonoid and vitamin E which can be used to reduce ROS reactions and inhibit oxidative stress. This research was to prove that kebar grass extract can increase diameter of the seminiferous tubules of diabetic mice. Total of 30 samples were divided into 5 groups: negative control group (K-) was given CMC-Na, positive control group (K+) was given metformin 2mg/kg, groups P1, P2 and P3 received 2mg/kg metformin and kebar grass extract with different dosages (67.5mg/kg, 135mg/kg and 270mg/kg). The treatment lasted for 35 days. On the 36th day the mice were sacrificed and the testes were taken, then histological observations were made with HE staining to measure the diameter of tubules. The result showed that there was a significant difference in the diameter of seminiferous tubules with p value=0,000. Kebar grass extract can increase the diameter of seminiferous tubules of diabetic mice.

This study was conducted to evaluate the effects of In ovo injection of β-Alanine which is a modified form of the alanine amino acid on hatchability, hatching weight, chick quality score and survival in broiler breeder eggs. For this purpose, 120 fertile eggs from Ross 308 breeder (32-week-old) were allocated randomly to four groups with 3 replicates. Except the negative control group eggs (non injected; NC), to the amniotic fluid of the eggs in the other 3 groups were injected with 1 ml solutions 0.9% salt (Positive control, PK), 0.75% (0.75βA) or 1.5% (1.5βA) by using 19 mm and 27 gauge needle. Death rates at the different stages of embryonic development, hatching yield, weights and quality scores of chicks and mortalities were recorded at hatching day. Hatching weight of the chicks in the 0.75βA group was higher than other two control groups. Accessing feed, determined as an indicator of chick quality, was better in the 0.75βA group. Conversely, mobility score of chicks in the NC group was higher than other groups. Hatching yield, chick quality score and mortalities of the first week were not affected from In ovo βA injection. Results of this study demonstrated that In ovo βA injection can be used up to 1.5% without any deteriorations on weight, quality and mortalities of chicks but 0.75% βA injection induced better hatching characteristics.

An experiment was conducted to determine the effects of two different water-soluble carbohydrate extracts (renga renga lily extract and Acacia extract), and two commercially available prebiotic compounds, Fibregum and Raftifeed-IPE, on the performance of broiler chickens subjected to a necrotic enteritis (NE) challenge model. These treatments were compared with negative control and a positive (Zn-bacitracin) control treatments. An overall 8.8% NE-related mortality was recorded, with mean jejunal and ileal lesion scores in dead birds ranging from 3.03 to 3.90 in all challenged groups except the positive control groups. NE-specific deaths or clinical abnormalities were not observed with unchallenged control and positive control groups. At 7 days post-challenge, the concentration of specific IgY antibodies against the α-toxin of Clostridium perfringens in the serum was lower (P < 0.05) in birds fed the positive control and Fibregum-supplemented diets than in the negative control group. However, birds fed Fibregum had increased (P < 0.05) IgM concentration compared with those fed Acacia extract and lily extract. The Fibregum-fed group also had higher (P < 0.05) IgA concentrations in serum than did the positive-control and lily extract-supplemented groups at 14 days but this effect did not persist to 21 days. The results from the present study demonstrated that supplementation with water-soluble carbohydrates from two plant sources was not effective in controlling NE. However, the prebiotic compound Fibregum was found to be having some immunomodulatory effects. Addition of Zn-bacitracin and monensin was highly effective in counteracting the negative effects of the disease challenge.

Aims: Homeopaths diverge on the concept of dose, i.e. the amount of drug that a patient must take to alter his or her state of disease. In order to stimulate reflections on this concept, this study sought to evaluate in vivo the effect of different concentrations of Arsenicum album 6cH prepared according to homeopathic pharmacotechnics. Methods: male Wistar rats were intoxicated with arsenic and then treated with Arsenicum album 6cH and Arsenicum album 6cH diluted at 1%, administered orally. The amount of arsenic retained in the animals’ organism and that eliminated by urine were measured through atomic absorption spectroscopy. Samples of urine were collected before and after intoxication and during treatment. The positive control group (intoxicated animals) and the negative control group (non-intoxicated animals) received only the vehicle used in the preparation of the medicine. Results: Groups treated with Arsenicum album 6cH and Arsenicum album 6cH diluted at 1% eliminated significant amounts of arsenic when compared to the control groups. The group treated with Arsenicum album 6cH eliminated significantly higher amounts of arsenic than the group treated with the diluted medicine at 1%. Conclusion: results suggest that Arsenicum album 6cH should not be diluted as not to compromise its effectiveness in the treatment of rats intoxicated with arsenic.

AbstrakTujuan penelitian ini adalah untuk menentukan efek pemberian minyak buah merah (pandanus conoideus lam) terhadap kadar glukosa darah dan malondialdehid (MDA) serum mencit yang diinduksi dengan aloksan. Induksi aloksan ini menyebabkan hiperglikemia yang dapat mencetuskan stres oksidatif. Minyak buah merah yang mengandung banyak antioksidan dapat mengendalikan stres oksidatif yang akhirnya dapat menurunkan kadar glukosa darah dan MDA serum.Penelitian eksperimental ini menggunakan 15 ekor mencit jantan yang diseleksi secara random. Hewan coba dibagi menjadi 3 kelompok masing-masing terdiri 5 ekor mencit, yaitu; kelompok kontrol negatif yang hanya diberikan makan dan minum, kelompok kontrol positif yang diinduksi aloksan, dan kelompok perlakuan (diberi minyak buah merah oral) yang diinduksi aloksan. Setelah perlakuan hari ke-14, darah mencit diambil untuk diperiksa kadar glukosa darah dan MDA serum.Hasil penelitian menunjukkan rerata kadar glukosa darah kelompok kontrol negatif adalah 141,20 ± 13,10 mg/dl. Rerata kadar glukosa darah kelompok kontrol positif adalah 266,00 ± 111,10 mg/dl. Rerata kadar glukosa darah kelompok perlakuan adalah 194,80 ± 27,00 mg/dl. Rerata kadar MDA serum kelompok kontrol negatif adalah 0,91 ± 0,10 nmol/ml. Rerata kadar MDA serum kelompok kontrol positif adalah 1,49 ± 0,34 nmol/ml. Rerata kadar MDA kelompok perlakuan adalah 0,97 ± 0,14 nmol/ml. Perbedaan bermakna kadar glukosa darah hanya antara kelompok kontrol negatif dengan kelompok perlakuan (p<0.05). Analisis statistik kadar MDA serum menunjukkan terdapat perbedaan bermakna antara kelompok kontrol positif dengan kelompok perlakuan (p< 0,05).Kesimpulan dari penelitian ini ialah minyak buah merah tidak mampu menurunkan kadar glukosa darah pada kelompok perlakuan, tetapi minyak buah merah mampu menurunkan kadar MDA serum pada kelompok perlakuan.Kata kunci: minyak buah merah, glukosa darah, MDA serum, mencit, aloksanARTIKEL PENELITIAN80AbstractThe objective of this studi was to determine the effect of red fruit oil (pandanus conoideus lam) on blood glucose and serum malondialdehyde in alloxan induced diabetic mice. Hyperglycemia in this mice could lead to oxidative stress. Red fruit oil contains high antioxidants that have capability to control oxidative stress, so blood glucose and serum MDA is reduced.This experimental study had been carried out to 15 rats (randomized group design) which divided into three group of five rats each, i.e. negative control, positive control (alloxan induced), and the group was treated by alloxan induced which followed by red fruit oil orally for 14 days. The result was analyzed by using one way Anova with confidence interval 95%.The result show that blood glucose in negative control was 141.20 ± 13.10 mg/dl. Blood glucose in positive control was 266.00 ± 111.10 mg/dl. Blood glucose in the group was treated by alloxan induced which followed by red fruit orally is 194.80 ± 27.00 mg/dl. The MDA level in negative control group is 0.91 ± 0.10 nmol/ml, positive control group is 1.49 ± 0.34 nmol/ml, and the group was treated by alloxan induced which followed by red fruit orally is 0.97 ± 0.14 nmol/ml. Blood glucose was significantly different between negative control and treated group (p<0.05). Serum MDA was significantly different between positive control group and the group was treated by alloxan induced which followed by red fruit orally (p<0.05).The conclusion is red fruit oil cannot reduce blood glucose level in the group was treated by alloxan induced which followed by red fruit orally, but it has capability to quench serum MDA level in this group.Key word: red fruit oil – blood glucose – serum MDA – mice – alloxan

AbstractSchistosomiasis is an acute and chronic disease caused by blood flukes (trematode worms) of the genus Schistosoma. Schistosomiasis is disease that are prevalent in or unique to tropical and subtropical regions. Previous studies have shown that the role of bone marrow mesenchymal stem cells (BMSCs) therapy in improvement of hepatic fibrosis. Therefore, the current study was designed to assess the therapeutic role of BMSCs in murine schistosomiasis mansoni. BMSCs derived male mice were intraperitoneal injected into female mice that received S. mansoni cercariae through subcutaneous route. Mice were divided into four groups: negative control group (noninfected non treated); positive control group (infected non treated); BMSCs treated group; and untreated group. Liver histopathology and immunohistochemically were evaluated. BMSC intraperitoneal injection resulted in a significant reduction in liver collagen, granuloma size, and significant increase in OV-6 expression in the Schistosomiasis treated mice group. There was overall improvement of the pathological changes of the liver. The findings support that BMSCs has a regenerative potential in the histopathology and function of the liver tissue by decreasing liver fibrosis.

The substantial increase in the number of elderly people in our societies represents a challenge for biology and medicine. The societies of the industrialized countries are subject to a progressive aging process that translates into an increase in the cardiovascular risk of the population. In the present work, the activity of catalase and superoxide dismutase was evaluated, as well as markers of oxidative stress (concentration of nitric oxide and total lipoperoxidation in its main components: malondialdehyde and 4-hydroxyalkene) in cardiomyocytes during the aging process in rats treated with resveratrol. Rats were divided into 4 groups according to the following categories: control (without treatment), negative control group (administered with physiological solution with 10% ethanol), positive control group (administered with vitamin E, 2 mg/kg/day), and group administered with resveratrol (10 mg/kg/day); these groups in turn were divided into 2, 4, 6, and 8 months of treatment. The analysis of nitric oxide showed a decreased level in the cardiac tissue in the groups treated with resveratrol; the same occurs when total lipoperoxidation is analyzed. The enzymatic activity studied (catalase and superoxide dismutase) did not present significant changes with respect to the controls. It is concluded that the cardioprotective effect of resveratrol is due to the antioxidant effect and other antiaging effects and not to the activation of the enzymes catalase and superoxide dismutase.

Blood selenium concentrations and liveweight gains were assessed for sheep grazing pastures treated with different selenium supplements over a 2-year period. Three 0.5 hectare irrigated blocks with pasture selenium concentrations of less than 0.04 μg/g DM were identified near Lincoln, Canterbury during 1997. Treatments applied in early November 1997 were: (1) 1 kg/ha of an experimental selenium product (SRSe5, containing 10g selenium); (2) 1 kg/ha of a commercially available slow release selenium product (positive control, containing 10g selenium) and (3) nil selenium treatment (negative control); all treatments used 60 kg urea/ha as the carrier. Treatments were stocked at 30 lambs/ha in November 1997. Liveweight gains and concentrations of blood selenium were monitored fortnightly for the first 4 months of the study and monthly thereafter. Following mating in April 1998, blood selenium concentrations and liveweight gains of spring born progeny were assessed. Ewes grazing the SRSe5 and positive control treatments had significantly greater concentrations of blood selenium than the negative control group and the concentrations for the SRSe5 group were significantly greater than from the positive control. Negative control ewes and their lambs were removed from the study at lambing due to low blood selenium concentrations and concerns regarding their health. Concentrations of blood selenium did not differ significantly between lambs of SRSe5 and positive control ewes born in the second year of the study. Lamb and ewe blood selenium concentrations were highly correlated. Liveweight gains did not differ significantly between SRSe5, positive control or negative control groups for ewes or lambs during either year of the study. This study demonstrated that the application of selenium to pastures is a highly effective longterm strategy by which concentrations of blood selenium may be elevated in sheep under New Zealand pastoral conditions. While liveweights did not differ significantly between treatments during either year of the study, the small numbers of animals used limited the power with which differences could be detected between treatments.
