Abstract  The potential of seaweed as a functional food ingredient has not been explored. Several studies, the compotition of seaweed can prevent stress in animals such as sedative mechanisms. The sedative effect was decreased of blood pressure. Pregnancy can be a stressor in animals and cause anemia physiologically. This study aims to determine the effect of seaweed extract on the profile hemoglobin and erythrocytes of pregnant mice. In this study used 10 pregnant rats divided into 2 groups, group 1 (control) and group II (treatment with 450 mg/BW extract Sargassum sp). Calculation of erythrocytes, hemoglobin, and thrombocyte measurements were carried out in day 0, 7, and 14. The results showed that there was an increased thrombocyte count in the treatment group even though in both groups there was a decreased the number of erythrocytes and hemoglobin. The results of statistical analysis showed a significant difference (p <0.05) of thrombocyte counts between the control and treatment groups. Based on the results of the study it was found that administration of Sargassum sp. during pregnancy can prevent thrombocytopenia in pregnant rat.  Keywords: Sargassum sp; Pregnant rat; Thrombocytopenia; Erythrocytes; Hemoglobin   Abstrak  Potensi rumput laut sebagai bahan pangan fungsional belum banyak digali. Beberapa penelitian telah menyebutkan kandungan rumput laut dapat mencegah stress pada hewan seperti mekanisme sedativa. Efek sedativa yang sering muncul adalah penurunan tekanan darah. Kebuntingan dapat merupakan stressor pada hewan dan secara fisiologi akan menyebabkan anemia. Penelitian ini bertujuan untuk mengetahui efek pemberian ekstrak rumput laut pada gambaran hematologi tikus bunting. Penelitian ini menggunakan 10 ekor tikus bunting yang dibagi menjadi 2 kelompok yaitu kelompok 1 (kontrol) dan kelompok II (perlakuan ektrak rumput laut Sargassum sp 450 mg/kg BB). Pengambilan sampel dilakukan pada hari ke 0 (sebelum kebuntingan), hari ke 7 dan hari ke 14 (akhir kebuntingan). Pengukuran hematologi sampel meliputi perhitungan eritrosit, pengukuran hemoglobin serta trombosit. Hasil penelitian menunjukkan bahwa terjadi peningkatan jumlah trombosit pada kelompok perlakuan meskipun pada kedua kelompok terjadi penurunan jumlah eritrosit dan hemoglobin. Hasil analisis statistik ada perbedaan yang signifikan (P<0,05) jumlah trombosit antara kelompok kontrol dengan perlakuan. Berdasarkan hasil penelitian didapatkan bahwa pemberian ekstrak Sargassum sp selama kebuntingan dapat mencegah terjadinya trombositopenia pada tikus bunting.  Kata kunci: Sargassum sp; Tikus bunting; Trombositopenia; Eritrosit; Hemoglobin

Objectives: Drugs can cause undesired effects on the fetus during pregnancy, especially embryonic/organogenesis which could lead to defects in the fetus because some types of drugs can penetrate the placenta and will undergo biotransformation into a highly reactive compound that has the potential to become a teratogenic compound. The aim of this research was to examine the teratogenic effect of bintangur leaves (Calophyllum soulattri Burm. F) ethanol extract to Sprague Dawley strain white rats. Methods: The white rats are divided into four treatment groups: Control group was given carboxymethyl cellulose Na 1%, comparison group was given trimethoprim 360 mg/kg BW, C. soulattri leaves ethanol extract (CLE) 100 mg/kg BW, and CLE 500 mg/kg BW. The treatment was administrated since organogenesis period. Cesarian section was performed to pregnant rat at the 20th day to separate the fetuses. Observation covered body weight of pregnant rats, fetal biometric, morphological malformation, and skeletal formation. Results: CLE 100 mg/kg BW and 500 mg/kg BW did not cause any change in the number of a living fetus, body weight, and length of fetuses like the comparison group. Both doses of CLE shown have a normal skeletal formation. Resorption was found in the comparison group and CLE 100 mg/kg BW with the percentage was 65.21% and 6.67%. It was found that there is no significant difference (p<0.05) between both doses of CLE compared to control group. Conclusion: From the results, it is concluded that CLE did not have the teratogenic effect.

The study was conducted to investigate the effects of caffeine treatment during organogenesis period to the fetal birth weight, using rat (Rattus norvegicus) as the animal model. Thirty-six primipararat obtained from Unit Pengembangan Hewan Percobaan, Gadjah Mada University (UPHP-GMU), 3 month old, 165-200 g body weight, were divided into 6 groups, consisted of 6 rats each. Six of the ratshave been selected based on the estrous cycles, and only rat with regular estrous were use for theexperiment. The rat then were mated, and during day 6-14 of the pregnancies were treated orally withcaffeine diluted in aquadest in dosage: placebo (1 cc aquadest) for group I (control), and 5.4, 10.8, 16.2,21.6, and 27 g/200 g body weight/day for treatment groups II-VI respectively. The pregnant rat bodyweights were determined at day 6 of pregnancies for calculating the caffeine treatment dosages. At day 20thof the pregnancies all of the pregnant rats were caesarotomized, and all of the fetuses were removed and weighed. The results showed that all of the treatment groups have significantly lower birth weightcompare to the groups control group. More over, fetal obtained from the treatment groups also showedserious subcutaneous hemorrhagic.Keywords: organogenesis, Rattus norvegicus, birth weight

The C14 content was determined of the livers, spleens, skeletal muscle, blood, feces, and urine of both pregnant and nonpregnant female rats and of the placentas, fetal livers, fetuses, and amnionic fluids of pregnant rats following the intravenous administration of 5 mg./kg. of either vitamin K1-C14 or vitamin K3-C14. The C14 concentrations of the livers of the rats given vitamin Kt were about 24 times larger than those of animals that had received vitamin K3-C14. A fivefold difference in the same direction exists between the concentrations in the spleens of the two groups. The C14 levels for skeletal muscle, blood, placenta, fetal liver, and fetal tissue were of similar magnitude regardless of whether vitamin Kt or vitamin K3 was administered. Isotope dilution tests revealed that following intravenous administration of vitamin K1-C14 the amount of radioactivity present as unchanged vitamin Kt-C14 was 12% for fetal tissue, 59% for placenta, and 120% for the maternal liver. The dry weights of the livers of pregnant rats were larger than those of nonpregnant rats and the increase was proportional to the live weight of the pregnant rat. No significant difference could be demonstrated in the percentage of the injected dose of vitamin K1 deposited in the livers of pregnant or nonpregnant rats. The same was true for vitamin K3-C14. The results of this experiment indicate that vitamin K3-C14 is not concentrated in the liver of the rat whereas vitamin K1-C14 is. Furthermore, it would appear that both vitamin K1 and vitamin K3 can pass the placental barrier of the rat.

Background: Most pregnant women living in high malaria endemic regions of Nigeria use herbal remedies for the management of malaria-in-pregnancy, rather than the commonly prescribed drugs. Remedies common to this area involve a suspension of A. indica (AI) leaves and in some cases, a suspension containing a mixture of AI and D.edulis (PS). Aim: This study examined the therapeutic efficacies of AI, PS, or a combination of AI and PS in a pregnant rat model for exoerythrocytic stages of Plasmodium falciparum parasite. Method: A predetermined sample size of 30 dams was used (for a power level and confidence interval of 95%), and divided equally into six groups made up of non-malarous dams, untreated malarous dams, and malarous dams either treated exclusively with 1 mL of 3000 mg/kg b.w AI, 1000 mg/kg b.w PS, AI + PS (50% v/v), or 25 mg/kg b.w CQ. Result: No maternal mortality was recorded. AI significantly improved maternal weight gain from 32.4 to 82.2 g and placental weight from 0.44 to 0.53 g. In the curative test, AI and AI + PS significantly reduced the average percentage parasitemia (APP) in the pregnant rats from >80% to <20%. No significant difference in the APP was found between the pregnant rats treated with any of CQ or AI during the suppressive test. Results for the prophylactic test of the study groups showed that the APP was significantly reduced from 24.69% to 3.90% when treated with AI and 3.67% when combined with PS. AI + PS reduced diastolic blood pressure from 89.0 to 81.0 mm/Hg and compared with that of the non malarous dams. AI or AI + PS significantly increased the platelet counts (103 µL) from 214.1 to 364.5 and 351.2, respectively. AI and AI + PS improved birth weight from 2.5 to 3.9 g and crown rump length from 2.6 to 4.1 cm. For biomarkers of preeclampsia, combining AI and PS led to the reversal of the altered levels of creatine kinase, lactate dehydrogenase, cardiac troponin, soluble Fms-Like Tyrosine Kinase-1, and placental growth factor. Conclusions: This study validates the use of A. indica for the treatment of gestational malaria due to its antiplasmodial and related therapeutic effects and in combination with pear seeds for the management of malaria-in-pregnancy-induced preeclampsia.

Abstract B cell precursor acute lymphoblastic leukemia (BCP-ALL) is one of the most common malignancies in children. In the period 1991-2013, the Dutch Childhood Oncology Group (DCOG) has completed three treatment trials for childhood ALL: ALL8, 9 and 10, each protocol with stratifications into risk-groups (details: www.skion.nl). Although the cure rates increased in these subsequent trials, relapses still occurred in a significant number of children. Since consecutive upfront treatment protocols usually change at multiple levels, genomic alterations that are associated with relapse may also be variable, which could provide insight into the biology underlying therapy failure and relapse. In this study, we characterized the genetic architecture of relapsed BCP-ALL patients within the context of these three Dutch upfront protocols. We identified 3 patient groups based on upfront treatment as follows: Group-1: patients treated upfront with high-amounts of corticosteroids (CS) and relatively mild additional chemotherapy (ALL9 NHR/HR); Group-2: patients treated with high-amounts of CS and intensive additional chemotherapy (ALL10 MR); Group-3: patients treated with low-amounts of CS and moderately-intensive additional chemotherapy (ALL8 SR/MR, ALL10 SR). The number of high-risk patients that relapsed after ALL8 HR and ALL10 HR chemotherapy courses was too low to be included for analysis. We determined, at relapse, the presence of copy number alterations and sequence mutations in 21 recurrently affected genes involved in B-cell development, cell cycle regulation and RAS signaling, in 123 patients that relapsed after treatment in group-1 (n=56), group-2 (n=20) and group-3 (n=47). The number of CREBBP mutations in patients that relapsed after treatment according to group-1 (ALL9) was significantly lower compared to the other two groups, whereas B-cell development alterations were most common in patients that relapsed after treatment according to group-1, mainly due to a higher number of IKZF1 alterations (Figure 1). The high number of relapsed patients with leukemic clones carrying IKZF1 alterations in patients treated with high-amounts of CS and relatively mild additional chemotherapy is in line with our recent finding that IKZF1 is a key determinant of GC-induced apoptosis in normal and leukemic B-cells, and that loss of IKZF1 function confers resistance to dexamethasone, the major treatment component in group-1 (Marke et al., submitted). Additionally, in the group-2 patients treated with high-amounts of CS and highly intensive additional chemotherapy, a lower percentage IKZF1-deleted clones was detected at relapse, indicating that more GC-resistant, IKZF1-deleted clones are killed by the intense chemotherapy given in addition to CS in group-2 patients. Similarly, in the group-3 patients relapsing after treatment with lower amounts of CS and moderately-intensive additional chemotherapy, the percentage of surviving IKZF1-deleted clones was lower than in patients treated with high-amounts of CS. Taken together, our data indicate that the genetic architecture of relapsed BCP-ALL patients depends on the upfront treatment and, in addition, that the poor-prognostic feature of IKZF1-deletions may be more prominent in upfront treatment with high-amounts of CS and relatively mild additional chemotherapy.

ABSTRACTObjectives: To assess the incidence of postoperative pain after single- and multi-visit endodontic treatment of teeth with vital and non-vital pulp.Methods: In total, 306 patients with teeth requiring endodontic treatment were identified and were included in this study. Two experienced clinicians treated the patients, who were randomly assigned to two groups. While the teeth of patients in group 1 were obturated, group 2 were temporarily sealed and obturated after one week. Three days after the root canal instrumentation of each tooth, the patients were asked whether they experienced any postoperative pain and to rate the level of discomfort as no, mild, moderate, or severe pain. Data were analyzed statistically using the chisquare test.Results: No significant difference in postoperative pain was found between vital and non-vital teeth (P>.01). Mild, moderate, and severe pain occurred in 31.4, 13.7, and 4.6% of vital teeth, respectively. Postoperative pain occurred in 107 (69.9%) and 106 (69.3%) teeth in the single- and multi-visit treatment groups, respectively. There was no significant difference in postoperative pain between the two groups (P>.01).Conclusions: The prevalence of postoperative pain did not differ between vital and non-vital teeth. The majority of patients in either groups reported no or only mild pain. (Eur J Dent 2009;3:273-279)

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.

ABSTRACT Relative levels of rat ovarian α inhibin (αI) and βA inhibin (βAI) mRNAs were measured during pregnancy by dot-blot hybridization of ovarian poly(A+) RNA. Follicular patterns of αI and βAI expression in contralateral ovaries from the same rats were also studied by hybridization histochemistry. Oligodeoxynucleotide probes specific for porcine αI and βAI were synthesized, 32P end-labelled and used as hybridization probes on dot-blots of ovarian RNA and frozen sections of ovarian tissue from pregnant rats. During pregnancy, levels of αI and βAI mRNAs remained fairly constant from day 7 after mating until parturition and then fell within 16 h post partum. In all ovaries observed, expression of inhibin genes was located in granulosa cells of healthy antral follicles. In general, the strongest signals for αI and βAI mRNAs were obtained in large follicles, with weaker signals in smaller follicles. Follicular patterns of αI and βAI expression during pregnancy were often dissimilar when βI and βAI were compared over a range of follicles. Considerable βI mRNA was detectable in some follicles in which βAI was reduced or undetectable, despite strong signals for both αI and βAI in an adjacent follicle. Essentially, αI mRNA levels were relatively consistent between groups of follicles, whereas βAI levels varied considerably. βAI mRNA was never observed in a follicle in the absence of αI mRNA, indicating that activin production in any follicle occurs in the presence of αI mRNA. Similar patterns of expression were observed in ovaries from pregnant mice. We have shown that expression of αI and βAI inhibin genes is not regulated uniformly within follicles of pregnant rat and mouse ovaries.
