The aim of the study is to determine the effectiveness of betamethasone in the treatment of local post-tattoo complications, depending on the mode of administration.Materials and methods. The work was carried out on 90 male rats which had been tattooed (n = 30 – a negative control group; n = 30 – a comparison group: a subcutaneous administration of 1 ml of a betamethasone solution; n = 30 – an experimental group: an administration of 1 ml of a betamethasone solution using a tattoo machine), 15 – intact rats. Withdrawal from the experiment took place on the 3rd, 10 th and 21st days. The skin samples were fixed in 10% formalin, followed by histological posting and manufacturing of micropreparations, then staining with hematoxylin and eosin, according to Van Gieson. A morphometric study included determination of the volume fraction (VF) of the epidermis; dermal fibers; pigment; inflammatory cells; macrophages (%), as well as the pigment depth (μm) and the severity of edema.Results. The study found out that in the process of the betamethasone administration using a tattoo machine, the drug was uniformly administrated over the entire area of the tattoo; hereby, the phenomena of edema and inflammatory infiltration were insignificant. The dermal fibers were located in each layer with no signs of edema and with single cells of inflammation, respectively. The data of the histological processing were completely consistent with the results of morphometry: it was found out that in the experimental group, edema significantly decreased, the volume fraction of the pigment and macrophages decreased, and the volume fraction of the dermal fibers increased. The estimation of the inflammatory reaction was carried out according to the morphometric parameters of the volume fraction of inflammatory cells and had significant differences in all the experimental groups, decreasing in the following series: the negative control group> the comparison group> the experimental group> the group of intact animals (p <0.05).Conclusion. Based on the data obtained, the effectiveness of betamethasone in the treatment of local post-tattoo complications has been proved. In this case, the treatment of choice is the administration of this drug not traditionally subcutaneously, but using a tattoo machine that enables the targeted delivery of the substance to the area of the pathological process.Abbreviations: NC – negative control, VF – volume fraction

Exposure to X-rays (ionizing radiation) may cause chromosomal aberrations (CA) in somatic or germinative cells in exposed individuals, and may lead to manifestations of diseases such as cancer. This study was carried out to assess the CA frequency in lymphocytes obtained by means of temporary culture of peripheral blood from dentists in Londrina, Paraná, Brazil, who have worked for more than ten years with X-rays. The results obtained from the experimental group were compared with a matched negative control group, which had never been exposed to X-rays. All individuals, dentists and controls, answered a personal questionnaire, from which a profile of each group was obtained. Slides, prepared after the cultures, were stained with Giemsa, and 100 to 200 metaphase cells were analyzed per individual. CA frequencies and types were registered and statistical tests were not necessary to evaluate the obtained data. The analysis of mitotic index (MI) did not indicate significant differences (p < 0.05) between the group of individuals exposed to X-rays and the control group. The analyzed confounding factors did not influence the results of MI and CA frequencies.

Abstract At any moment, the continuous usage of medications can accompanied by DNA damage and the accumulation of such damages can cause serious consequences. Antidepressants are long-term used drugs and the incidence of their genotoxic impacts cannot be excluded. Therefore, this work was designed to investigate the possible genotoxic effects of the commonly used antidepressants (fluoxetine and amitriptyline) in adult male rats. Detection of DNA damage in individual cells was assessed by comet and micronucleus assays in three different cell populations i.e. liver, testis and bone marrow tissues of 24 swiss albino adult male rats. The animals were randomly allocated into three groups of 8 rats each: Group I - rats orally-administered distilled water via gavage tube for four weeks as a negative control. Group II - rats orally-treated with fluoxetine hydrochloride solution (7.2mg/kg/day) via gavage tube for four weeks. Group III - rats orally-treated with amitriptyline hydrochloride solution (27mg/kg/day) via gavage tube for four weeks. The results showed that both drugs (Group II and Group III) induced the same extent of DNA damage, as evidenced by a significantly higher DNA fragmentation in liver and testis tissues with increased frequencies of micronuclei formation in bone marrow tissues as compared with the negative control (Group I). These findings indicates that both Fluoxetine and Amitriptyline have genotoxic potentials and can induce the same extent of cytogenetic damage in rats. Special precautions and medical supervision should be taken in consideration with their uses.

Diazinon is an insecticide that has a higher toxicity than other insecticides. Normally, insecticides are detoxified by liver, but this process produced free radicals which causes cell damage. Free radicals also increase lipid peroxidation which directly increase malondialdehyde levels. This research was aimed to determine the influence of diazinon toxicity to the liver histopathology and levels of malondialdehyde (MDA) in the serum of rats (Rattus norvegicus). The rats were divided into 4 groups which consist of negative control group and three experimental groups which were given diazinon 20 mg/kgBW (P1), 40 mg/ kgBW (P2), and 60 mg/ kgBW (P3). The rats were given diazinon for 8 weeks orally. The parameters used in this research was liver histopathology with hematoxilin eosin stain and Malondialdehyde levels with Thiobarbituric test. Liver histopathology was analyzed in descriptive qualitative and the level of MDA was analyzed quantitatively using ANOVA and Tukey's exact test with α = 0.05. The result of this research showed the influence of organophosphate (diazinon) on liver histolopathology was shown by inflammatory cells infiltration in hepatic parenchyma, sinusoidal congestion, and cytoplasmic vacuolation of the hepatocytes. Statistical analysis proved that the diazinon was able to increase the level of MDA serum significantly (p<0,05) up to 71% in experimental group P1 (dose 20 mg/kgBW), which the increase level of MDA serum depend on dose of diazinon. This research concluded that diazinon is one of the organophosphate pesticide that toxic based on liver histopathology and MDA serum levels.

Introduction: Some studies indicated that antlions (Myrmeleon sp.) is traditionally used by many people in Indonesia as a diabetes treatmenter. However. reseach has not been done to find the effect of antlion extract in pancreas, an important organ in diabetes mellitus pathophysiology. Objective: To prove the effect of antlion extract towards histopathological feature of pancreas in diabetic mice.Methods: In the post test only control group design, 25 Swiss mice were divided into five groups. Normal group (Nor-G), Negative control group (Neg-G), and the other 3 groups were intraperitoneally injected with Streptozotocine 200 mg/kg to induce diabetic state. In Neg-G had no antlion treatment, whereas in At-14, At-28, and At-56 were treated with antlion extract at the dose of 14, 28, and 56 mg/kg BW respectively for 24 days. Pancreas then collected and prepared to be examined under microscope with 400x magnification. The score of pancreatic islet injury was determined by assessing structural damage and inflammatory cells infiltration. Kruskal-Wallis and Mann-Whitney were adopted as statistical analysis.Results: Mann-Whitney analysis indicated that the score of pancreatic islets injury in At-56 was significant lower compared to that of Neg-G, p<0.05. The score of pancreatic islets injury in At-56 also significant lower compared to that of At-14 and At-28, p<0.05. In contrary, when compared to that of Nor-G, the pancreatic islets injury in At-56 was not signicantly lower, p>0.05.Conclusion: Antlion extract treatment at the dose of 56 mg/kg BW was capable of reducing pancreatic islet injury in diabetic mice induced by streptozotocine.

Abstract Aim evaluate antioxidant and anti-anaemia activity of dichloromethane, hydroethanolic, and alkaloids-free hydroethanolic extracts of beetroot (Beta vulgaris (L.) subsp. vulgaris) on phenylhydrazine-induced rats. Methods Male rats were divided into five groups: normal control group, negative control group, dichloromethane extract group, hydroethanolic extract group, and alkaloids-free hydroethanolic extract group. All groups were induced with phenylhydrazine (30 mg.Kg−1 BW) for three days, except for the normal control group. After induction, each treatment group received each extract (200 mg.Kg−1 BW) for 21 days. The haematology parameters (haemoglobin levels, the number of erythrocytes, and haematocrit levels) were measured using Haematology Analyzer, and the antioxidant activity was measured through MDA level parameters in rats. Data were analysed using one-way ANOVA and then continued with the Tukey test. Results The results showed that the hydroethanolic extract of beetroot increased the percentage of erythrocytes (33.5%), haemoglobin (25%), and haematocrit (24.4%) to the negative control group, which was comparable to the normal control group (p > 0.05). In addition, the best antioxidant activity was shown in the hydroethanolic extract of beetroot, which is comparable to the normal group (p > 0.05). Conclusion The beetroot hydroethanolic crude extract could be potentially produced in a natural pharmaceutical product as a beneficial resource within anti-anaemia and antioxidant activities.

ABSTRACTObjective: The objective of this study is to explore the effects of the 70% ethanolic extract of pearl grass on the immune system of the osteoarthritismodel rat, characterized by the number of leukocytes and lymphocytes, and the histology of the joint. Osteoarthritis is a degenerative diseasecharacterized by chronic inflammation in the joints. Based on the daily practice of herbal medicine in some community in Indonesia, pearl grassusually used for anti-inflammation but not a lot of data to support it.Methods: We used 36 male rats Sprague-Dawley strain divided into 6 groups. Normal group was given 0.5% of CMC, the negative control group was given0.025 ml of sodium iodoacetate in 0.9% saline, the positive groups control group was given a suspension of glucosamine-chondroitin 135 mg/200 g bb,three were given pearls grass extract in various dose 5.625 mg, 11.25 mg, and 22.5 mg, respectively. 28 days after sodium iodoacetate induction, the extractswere given orally once daily for 21 days. Measurement of inflammation of knee joint and the number of leukocytes and lymphocytes were counted on day14th, 28th, and 49th after sodium iodoacetate induction. After treatment, all rats were sacrified and all knee joints were collected to subject for histology.Results: The results showed that the extract of pearl grass in all doses was able to decrease the number of leukocytes and lymphocytes significantlyand prevent proteoglycan degradation. The results showed that the extract of pearl grass with a given dose variations have antiinflammation effectand been able to protect proteoglycan significantly.Conclusion: Doses 3 (22.5 mg/200 g BW) is the best result. These results indicate that pearl grass can be further investigated as a treatment for osteoarthritis.Keyword: Osteoarthritis, Sodium iodoacetate, Pearl grass, Hedyotis corymbosa L.

Membranes that aid the guided bone regeneration (GBR) process have been the subject of studies of compatible biomaterials that contribute to this repair process. The present study compared different membranes used in critical-size defects of rat calvaria by assessing GBR as well as histological, histomorphometric, and immunohistochemical reactions. Forty-eight male albino Wistar rats were randomly allocated into four groups (n = 12 each), namely, C: membrane-free control group (only blood clot, negative control group); BG: porcine collagen membrane group (Bio-Gide®, positive control group); GD: bovine cortical membrane group (first experimental group); and GDF: thicker bovine cortical membrane group (second experimental group). Rats were euthanized at 30 and 60 days postoperatively. Quantitative data from the histometric analysis were submitted to two-way ANOVA and Tukey’s posttest when p<0.05. Histomorphometric results of the thicker bovine cortical membrane at 30 and 60 days were promising, showing improved new bone formation values (p<0.05), and the CD group presented similar results in both analysis periods, being surpassed only by the GDF group (p<0.05). The immunohistochemical results were associated with the histomorphometric data. A less-thick membrane also assisted in GBR. All membranes promoted GBR, especially the positive control and experimental groups.
