Up to now, there are no studies that have shown a decrease in morbidity and mortality in the context of sepsis and septic shock, except for antibiotic therapy and the objective-guided resuscitation strategy. The goal was to evaluate the use of thiosulfinate-enriched Allium sativum extract (TASE) as an adjuvant in the management of sepsis. An experimental in vivo study was carried out with male Sprague Dawley® rats. Animals were randomized in three treatment groups: the control group (I), antibiotic (ceftriaxone) treatment group (II) and ceftriaxone plus TASE treatment group (III). All animals were housed and inoculated with 1 × 1010 CFU/15 mL of intraperitoneal Escherichia coli ATCC 25922. Subsequently, they received a daily treatment according to each group for 7 days. Clinical, analytical, microbiological, and histopathological parameters were evaluated. Statistically significant clinical improvement was observed in the ceftriaxone plus TASE vs. ceftriaxone group in weight, ocular secretions, whiskers separation and physical activity level (p ≤ 0.05). When comparing interleukins on the third day of treatment between II and III, we found statistically significant differences in IL-1 levels (p < 0.05). Blood and peritoneal liquid cultures of group I were positive for multisensitive E. coli. Group II and III cultures were negative for E. coli, although an overgrowth of Enterococcus faecalis was found. In conclusion, TASE used as an adjuvant to antibiotic treatment in the management of sepsis could improve response profiles with sepsis attenuation, thus reducing overall mortality after an animal peritonitis model.

Background: Inflammation is a body response caused by injury and infection. Pulpitis is a pulp tissue inflammation which is the continuous process of pulp hyperemia by bacteria invasion. Myrmecodia pendans or Sarang semut is known to contain flavonoid compound which has the anti inflammation effect. The purpose of this study is to investigate the effect of Myrmecodia pendans ethanol extract on the healing process of pulp inflammation.Materials and Methods: This experimental study involved pre- and post-in vivo treatment of 27 Sprague Dawley rats in which the inducted pulpitis model was obtained by injecting 0.01 mL Porphyromonas gingivalis into the dental pulp for 48 hours. Subjects were divided randomly into Group I (negative control), Group II (pulpitis treated by Myrmecodia pendans extract ethanol as treatment group), and Group III (pulpitis treated by Ca(OH)2 as positive control group). Group II and III as pulpitis treatment groups were divided into subgroups based on the induction periods of 48 hours (2 days), 168 hours (7 days), and 366 hours (14 days). All specimens were processed into the slides and evaluated microscopically for the healing process.Results: The result of this study showed significant difference (p<0.05) among groups on day 2, 4 and 7. On day 4, the pulpitis treatment group of Myrmecodia pendans extract showed better healing process than Ca(OH)2. On day 7, the pulpitis treatment group of Ca(OH)2 showed better healing process than Myrmecodia pendans extract. On day 14, both of the pulpitis treatment groups showed normal pulp.Conclusion: Myrmecodia pendans ethanol extract is effective for the healing process of inflamed pulp.Keywords: inflamed pulp, Myrmecodia pendans, sarang semut, Ca(OH)2 , healing process

  The niacin in energy drinks has metabolic product that cause oxidative stress and liver damage, while the liver damage can be prevented by hepatoprotective agents. Scoparone in Artemisia vulgaris L. can act as a hepatoprotector by its antioxidant effect. This study aimed to investigate the effectivity of Artemisia vulgaris L. extract as a hepatoprotector in wistar hepatocytes induced by niacin. This study used 25 male rats which were divided into 5 groups: normal, the negative control, the positive control, the treatment group I, and II. Treatment was conducted for 28 days. The samples were terminated and the hepatocyte were prepared for histological examination. Histological appearance was catagorized as mild, moderate, and severe damage with or without inflamatory cells activity. The data analysis by Kruskal Wallis showed significant difference (p<0,001). Further analysis by Mann Whitney revealed significantly difference (p<0,05) between normal group and all groups, negative control group and positive control group, and positive control group and treatment group I, but not significantly difference between negative control group and treatment group I, negative control group and treatment group II, positive control group and treatment group II, and between treatment groups. The study concluded that the effectivity of Artemisia vulgaris L. extract has not been proven as a hepatoprotector but further study is needed to draw a definite conclusion.   Keywords: energy drink, niacin, Artemisia vulgaris L., hepatoprotector

Background: Periodontitis is an inflammatory disease caused by specific microorganisms that attacks tooth-supporting tissues, P. gingivalis bacteria are mostly found in patients suffering from chronic periodontitis which is usually diagnosed by means of clinical and radiographic examination. The latter play important roles in the management of periodontitis, including: establishing diagnosis, determining treatment plans and evaluating the results of treatment. Unfortunately, the use of X-rays to perform such radiographic examination has negative effects since the body’s various parts, especially the head, are not well protected from the effects of X-ray radiation. Purpose: This research aimed to analyze the effects of dental X-ray exposure on the number of macrophages and lymphocytes in experimental subjects suffering from periodontitis. Methods: 36 rats that had been diagnosed with chronic periodontitis were divided into three groups, namely: a control group, treatment group I (exposed to a 0.16 mSv dose of radiation) and treatment group II (exposed to a 0.32 mSv dose of radiation). These subjects were subsequently sacrificed on the third and fifth days after treatment. Thereafter, histopathological examination was performed to identify any changes in the number of macrophages and lymphocytes. Results: The results of an HSD test confirmed that, on the third day, there were significant differences in the number of lymphocytes between the control group and treatment group I, as well as between the control group and treatment group II. On the fifth day, there were also significant differences in the number of lymphocytes between the control group and treatment group I, as well as between treatment group I and treatment group II. Similarly, there was a significant difference in the number of macrophage cells on the third day between the control group and treatment group I. On the fifth day, there were also significant differences in the number of macrophage cells between the control group and treatment group I, as well as between treatment group I and treatment group II. Conclusion: Dental x-ray exposure at a dose of 0.16 mSv can elevate the number of macrophages and lymphocytes on the third and fifth days. On the other hand, dental x-ray radiation at a dose of 0.32 mSv can reduce the number of macrophages on day 3 as well as the number of lymphocytes on the third and fifth days.

MSG causes many side effects on the body, but MSG has long been used as a food flavor that can bring tastes (umami) and play a role in strengthening the taste. The chemical structure of MSG is no different from Glutamic Acid (glutamate), it is one of the 20 amino acids that make up proteins in the body. So the use of MSG needs to be discontinued to prevent kidney damage due to continued consumption of MSG, two research were conducted to determine the effect of discharging of MSG consumption by being given tomato juice (1) and discharged without treatment (2), the second study was seen from the histology picture of rats wistar mouse.Methods were experimental with post test only control group design. The research (1) used 15 wistar rats divided into three groups: group I without treatment (pellet AD II and drinking water), group II was given MSG for 14 days and group III was given tomato juice and MSG for 14 days. The study (2) used 27 rats divided by 9 groups. The sample is selected by simple random sampling method. The mice were then gradually turned off on the 29th, 43rd and 57th days. There was no significant difference in mean number of normal and damaged proximal tubules in all treatment groups. The renal histologic features in the treatment group I (MSG) and the treatment group II (MSG and tomato juice) showed normal glomeruli, tubular epithelial tubules, and lumen tubular narrowing whereas in mice discharged without treatment there was no apparent difference between the two MSG Giving groups damage to proximal tubules and renal corpusculum and regeneration after 14 days of discontinuation of MSG. Conclusions from these two experiments occurred damage to the renal tubules Keywords: MSG, Kidney, Wistar Rat

The aim of this study was to evaluate the pretreatment hepatoprotective effect of the extract of marine-derived fungusTrichurus spiralisHasselbr (TS) isolated fromHippospongia communissponge on hepatotoxicity. Twenty-eight male Sprague-Dawley rats were divided into four groups (n=7). Group I served as −ve control, group II served as the induced group receiving subcutaneously for seven days 0.25 mg heavy metal mixtures, group III received (i.p.) TS extract of dose 40 mg for seven days, and group IV served as the protected group pretreated with TS extract for seven days as a protection dose, and then treated with the heavy metal-mixture. The main pathological changes within the liver after heavy-metal mixtures administrations marked hepatic damage evidenced by foci of lobular necrosis with neutrophilic infiltration, adjacent to dysplastic hepatocytes. ALT and AST measurements show a significant increase in group II by 46.20% and 45.12%, respectively. Total protein, elevated by about 38.9% in induction group compared to the −ve control group, in contrast to albumin, decreased as a consequence of metal administration with significant elevation on bilirubin level. The results prove that TS extract possesses a hepatoprotective property due to its proven antioxidant and free-radical scavenging properties.

Abstract To study the therapeutic effect of Armillarisin A on patients with ulcerative colitis (UC) and on serum IL-1β and IL-4, sixty patients with UC were randomly divided into three groups: Armillarisin A treatment group (Group I), Armillarisin-combined hormone therapy group (Group II), and hormones treatment as the control group (Group III). Patients in Group I received Armillarisin A 10 mg enema in 100 ml saline. Patients in Group II received Armillarisin A 10 mg and dexamethasone 5 mg enema in 100 ml saline. Patients in Group III received only dexamethasone 5 mg enema in 100 ml saline. The therapeutic efficacy and serum levels of IL-4 and IL-1β were observed. After 4 week treatment, the total effective rates were 90.0 % in Group I and 95.0 % in Group II. Both are higher than it in control group, which was 70.0 %. The serum levels of IL-4 in Groups I and II were significantly higher than it in control group. Compared to IL-4 levels before treatment, the levels of IL-4 after treatment were significantly higher in both Groups I and II. The serum levels of IL-11β were significantly decreased in Groups I and II in comparison to it in control group. Compared to the levels of IL-1β before treatment, the levels of IL-1β were significantly decreased. Armillarisin A shows a significant effect in treating UC. It helps increase IL-4 and lower IL-1β and the mechanism may be related to the body’s immunity regulation.
