ABSTRACTSpiral artery apoptosis plays a role in the process of abortion. Low Bcl2 expression found in abortion and in spiral artery. In pregnancy, Toxoplasmosis infection is found to increase apoptosis in spiral arteries. Hyperbaric Oxygen Therapy (HBOT) improves the expression of Bcl-2. This study aims to determine the effects of Hyperbaric Oxygen therapy in enhancing the expressions of Bcl2 in artery spiralis of pregnant rats infected with tachyzoite of Toxoplasma gondii. This is an experiment with a ‘randomized control group of post-test only design’ on 37 Rattus novergicus Sprague Dawley rats. Rats were divided into four groups. The group A is pregnant rats infected with 103 tachyzoites via intraperitoneal injection and received 10 sessions of HBOT 2.4 ATA in 3x30 minutes. Group B is pregnant only and received HBOT. Group C is pregnant and infected with tachyzoite but did not received HBOT. And the last, Group D is pregnant rats with no infection and did not received HBOT. Examinations of Bcl2 expressions were performed on day-5 after HBOT (twice a day). The Bcl2 expression was measured with immunohistochemistry. All data were tested with One-way ANOVA from SPSS 21.  There is an increased expression of Bcl2 spiralis artery in the Group A. There was a significant difference between Group A and Group C with a value of p=0.042. HBOT can increase the expression of Bcl2 from the spiral arteries of rats, in the provision of HBOT 2.4 ATA for 3x30 minutes, 10 times in 5 days.Keywords: Toxoplasma gondii, tachyzoite, Hyperbaric Oxygen Therapy, Bcl2, spiralis arteryCorrespondence to: [email protected]  ABSTRAK Apoptosis arteri spiralis berperan dalam proses aborsi. Ekspresi Bcl2 rendah ditemukan pada aborsi dan di arteri spiral. Pada kehamilan, infeksi Toxoplasmosis ditemukan meningkatkan apoptosis pada arteri spiralis.

Hyperbaric Oxygen Therapy (HBOT) can increase oxygen delivery to tissues and stimulate the formation of H2O2 as a secondary messenger for phosphorylation of nuclear factor kappa beta (NF-kB) which plays an important role in the transcription of the anti apoptotic gene. This study aimed to determine the effects of Hyperbaric Oxygen Therapy (HBOT) in enhancing the expressions of Bcl-2 in the myometrium of pregnant rats infected by Toxoplasma gondii. This study was an experimental study with a randomized control group of post-test only and designed by 37 pregnant Rattus norvegicus Sprague Dawley. Randomly, the rats were divided into four groups. Group A is infected pregnant rats that exposed by 10 sessions of HBOT 2.4 ATA in 3x30 minutes. Group B is non-infected pregnant rats and exposed by 10 sessions of HBOT 2.4 ATA in 3x30 minutes. Group C is infected pregnant rats without any exposure. Group D is non-infected pregnant rats without any exposure. Each infected pregnant rat was given a 103 tachyzoite of T.gondii by intraperitoneal injection. Bcl-2 expressions were measured through immunohistochemistry. All data were analyzed using ANOVA test through SPSS 21 program application. There was a significant difference in Bcl-2 expression between Group A and Group C because p<α (p<0.017). HBOT can increase the expression of Bcl-2 from infected and not infected rat myometrium, in the provision of HBOT 2.4 ATA for 3x30 minutes, twice a day for 5 days.

PURPOSE: To evaluate hyperbaric oxygen therapy (HBO) after esophagojejunal anastomosis in a rat experimental model and the effect of HBO on the healing of esophagojejunal anastomosis in gastrectomized rats. METHODS: Forty adult male Wistar rats, weighing 322 g to 506 g, were divided into two random groups. In group A (control group), 20 rats were subjected to total gastrectomy. In group B, 20 rats were similarly gastrectomized, but also received postoperative HBO treatment for 90 minutes/day for seven days. All rats were sacrificed on the eighth postoperative day and evaluated according to the following study variables: a) presence of anastomotic fistula; b) evaluation of esophagojejunal anastomosis healing by measuring the breaking strength at the suture line as per Hendriks & Mastboom; and c) determining the collagen concentration in the anastomosis, as per Kovács criteria. For the comparative statistical analysis between groups, Student's "t" test was used. A value of p<0.05 was considered significant. RESULTS: There was a 20% mortality rate. There were five deaths in group A and three in group B (p=N.S.). There was only one anastomotic fistula in each group, and neither caused any morbidity or death. Breaking strength measured at the suture line (p=0.528) and collagen concentration determined at the esophagojejunal anastomosis (p=0.89) were not significantly different between Groups A and B. CONCLUSION: Hyperbaric oxygen therapy did not affect the healing process of esophagojejunal anastomosis.

Abstract Objectives This study aimed to examine the impact of hyperbaric oxygen therapy (HBOT) on serum C-reactive protein (CRP) levels, osteoclast numbers, and osteoprotegerin (OPG) expression in periodontitis-induced diabetic rats Materials and Methods This study constituted an in vivo laboratory-based experiment incorporating a posttest only control group design. Thirty male Wistar rats were divided into three groups of research subjects: a healthy group (K0), periodontitis-induced diabetic group (K1), and periodontitis-induced diabetic group treated with HBOT for 7 days (K2). After treatment, the subjects were sacrificed to determine the level of serum CRP by the ELISA method. Immunohistochemical analysis was conducted to check the level of OPG expression, while a histological analysis was undertaken to quantify the number of osteoclasts. Statistical Analysis The data was analyzed using a one-way ANOVA and Least Significant Difference (LSD) test on which a result of p < 0.05 was considered statistically significant. Results HBOT appreciably decreased serum CRP levels, significantly enhancing OPG expression in periodontitis-induced diabetic (p < 0.05) and decreasing the number of osteoclasts in -periodontitis-induced diabetic (p > 0.05). Conclusion HBOT reduced the serum CRP level, increased OPG expression, and decreased osteoclast numbers in periodontitis-induced diabetic rats.

Abstract The aim of the present study was to investigate the effect of hyperbaric oxygen therapy (HBOT) on colon anastomosis after chemoradiotherapy (CRT). Sixty female Wistar-Albino rats were divided into 5 groups and underwent left colon resection and end-to-end anastomosis. CRT simulation was performed on 2 sham groups before the anastomosis, and 1 of these groups was administered additional postoperative HBOT. Two groups were administered CRT before the anastomosis, and 1 of them received additional postoperative HBOT. On postoperative day 5, all groups underwent relaparotomy; burst pressure was measured and samples were obtained for histopathologic and biochemical analysis. There was a significant weight loss in the CRT groups and postoperative HBOT had an improving effect. Significantly decreased burst pressure values increased up to the levels of the controls after HBOT. Hydroxyproline levels were elevated in all groups compared to the control group. Hydroxyproline levels decreased with HBOT after CRT. No significant difference was observed between the groups regarding fibrosis formation at the anastomosis site. However, regression was observed in fibrosis in the group receiving HBOT after CRT. Preoperative CRT affected anastomosis and wound healing unfavorably. These unfavorable effects were alleviated by postoperative HBOT. HBOT improved the mechanical and biochemical parameters of colon anastomosis in rats.

<p><strong><em> </em></strong></p><p><strong><em>Background: </em></strong><em>Oral candidiasis generally caused by Candida albicans with prevalence of 30-50%. C. Albicans proliferation in the oral cavity was canducted by decreasing immune system of the host. Lymphocytes activation in immune system happened when there is a contact between host cell with cell wall of C. albicans as a result of C. albicans antigen. One of therapy to suppress the Candida infection sistemically is by giving hyperbaric oxygen therapy. <strong>Purpose: </strong>To determine the effects of giving hyperbaric oxygen therapy to the amount of lymphocytes in oral candidiasis immunosuppressed models. <strong>Methods:</strong> This research was post test only control group design. We used 12 wistar rats which were divided into 3 groups(n=4/3): K-(normal/ healthy wistar rats), K+(oral candidiasis immunosuppressed wistar rats), P1(oral candidiasis immunosuppressed wistar rats which were given hyperbaric oxygen therapy 5 days). K+ and P1 groups were immunosuppressed by giving dexamethasone 0,5mg/day/rat orally for 14 days, added with tetrasiklin 1 mg/day/rat. On the 3rd day immunosuppression, the rats were inducted with C.albicans smeared in the dorsum linguae once every two days for 12 days. <strong>Results:</strong> The data were analyzed with one way Anova test and showed significant difference among groups (p&lt;0,05). To show the difference between each groups we used LSD test and showed significant difference (p&lt;0,05) between K+ compared with P1, and K+ compared with K-. <strong>Conclusion:</strong> Hyperbaric oxygen therapy gives effect to the amount of lymphocytes in oral candidiasis immunosuppressed models.</em></p><p><em> </em><strong><em>Keywords:</em></strong><em> Oral candidiasis, immunosuppressed, hyperbaric oxygen therapy, lymphocytes</em></p><p> <strong><em>Correspondence</em></strong><strong><em>: </em></strong><em>Agni Febrina Pargaputri</em><em>, Departmen</em><em>t of</em><em> Oral </em><em>Biology </em><em>F</em><em>aculty of</em><em> </em><em>Dentistry</em><em>, Jl.

PURPOSE: To research the hyperbaric oxygen therapy effects on rats' livers and spleens. METHODS: 30 adult male Hotzman rats were used, being randomly distributed, by raffle, into 2 groups of 15 animals each: group 1 - control; group 2 - hyperbaric oxygen therapy. Group-2 animals underwent hyperbaric oxygen therapy for 120 minutes daily, 90 minutes of which were under pressure of 2.5 atmospheres. The first and last 15 minutes were used for gradual compression and decompression, respectively, for 20 days in a row. The livers and spleens of the animals from the two groups were taken out for histologic examination, on the day after the end of hyperbaric oxygen therapy in group 2 animals. Liver and spleen histologic changes of the animals from the two groups were compared by using Fisher exact test. P < 0.05 was regarded as a significant difference. RESULTS: The only change in liver and spleen histology was the significant reduction in hepatic extramedullary erythropoiesis in the animals that underwent hyperbaric oxygen therapy (p < 0.05). CONCLUSION: Hyperbaric oxygen therapy reduces hepatic extramedullary erythropoiesis in rats and doesn't jeopardize the other liver and spleen structures.

PURPOSE: To evaluate the effect of hyperbaric oxygen therapy on the survival and weight of rats submitted to subtotal splenectomy and on the viability and growth of the inferior pole. METHODS: Forty Wistar rats underwent subtotal splenectomy with preservation of the inferior pole and distributed into two groups: Group A (n=20) - not treated with hyperbaric oxygen, Group B (n=20) - treated with hyperbaric oxygen. These groups were divided into two subgroups of 10 animals each, according to the time of euthanasia, 15th and 45th days. The survival and weight of the animals were recorded. The inferior pole was measured, weighed and morphologically analyzed. RESULTS: All animals survived. The weight of the animals increased in all subgroups, but decreased on the 10th day in the subgroups treated with hyperbaric oxygen (p<0.001). The viability of the inferior pole was more evident in animals treated on the 15th day, but did not differ on the 45th day. The growth of the inferior pole has not occurred on the 15th day but on the 45th day after surgery in untreated animals (p<0.01) and treated animals (p<0.05). Vascular and cellular increase in treated animals was significantly higher than in untreated ones. CONCLUSION: Hyperbaric oxygen therapy did not affect the survival of animals but reduced their weight. It improved the viability of the inferior splenic pole, but did not interfere with their growth.
