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.

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 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.

The expression of hepatic multidrug resistance-associated protein (Mrp)1, 2, 3, and 6 and organic anion transporting polypeptides (Oatp)1 and 2 were examined in control and 20- to 21-day pregnant rats. Western analysis showed that expression of Oatp2 was decreased 50% in pregnancy, whereas expression of Oatp1 did not change. Expression of Mrp2 protein determined by Western analysis of total liver homogenate decreased to 50% of control levels in pregnant rats, consistent with studies using plasma membranes. Confocal immunohistochemistry showed that Mrp2 expression was confined to the canalicular membrane in both control and pregnant rats and was not detectable in intracellular compartments. In isolated perfused liver, the biliary excretion of 2,4-dintrophenyl-glutathione was significantly decreased in pregnancy, consistent with decreased expression of Mrp2. The expression of the basolateral transporter Mrp1 was not altered in pregnancy, whereas expression of Mrp6 mRNA was decreased by 60%. Expression of Mrp3 was also decreased by 50% in pregnant rat liver, indicating differential regulation of Mrp isoforms in pregnancy. These data also demonstrate that decreased Mrp2 expression is not necessarily accompanied by increased Mrp3 expression.

Preeclampsia/eclampsia (PEE) was the main cause of death in pregnancy. However, until now, this disease has no adequate medical prevention for lack of its basic molecular pathomechanism. In recent years, there are growing number of study has concern trophoblast apoptosis as important trigger. Thropoblast apoptosis has been shown in many report lead to trophoblast failure to invade into endometrial tissue. Invasion failure of trophoblast was characterized with high expression of IL-17 in its tissue. Spirulina arthrospira plant or also called blue-green algae has been consumed since by the Aztec tribe. Several studies have proven that this plant have the immunomodulation properties stimulate various immune functions such as production of cytokines, chemokines and other anti-inflammatory mediators. Its active bioactive Phycocyanin (PC) has been shown have an effect as anti-inflammatory and antioxidant. Previous study has been shown that this substance has beneficial effect in preeclampsia inhibition in rat models via its inflammatory reducing effect However, there are lack of information concerning its role in trophoblast IL-17. Hence, this study is conduct to reveal its role in IL-17 expression in trophoblast in preeclampsia. Methods. This research used animal models with PE/E pregnant rat. PE/E induced by IL-6 intravein at dose 5 ng/100 g/day body weight. Animals divided in 6 groups of treatment with two groups control and four groups of PC treatment in different dose. After decapitated, uterus tissue processed to view its IL-17 expression using immunofluoresnce Result. This study has proven IL-17 reducing effect of PC in preeclampsia model of pregnant rats induced by IL -6. PC has reducing IL-17 expression significantly in trophoblast tissue of pregnant rats models induced by IL-6 at dose of 40 ng/100 kg weight. Conclusion. This study confirm that PC has a protective effect on pregnant rats preeclampsia through its inhibiton of trophoblast IL-17.

Pregnancy is characterized by plasma volume expansion due to Na+ retention, driven by aldosterone. The aldosterone-responsive epithelial Na+ channel is activated in the kidney in pregnancy. In the present study, we investigated the aldosterone-responsive Na+-Cl− cotransporter (NCC) in mid- and late pregnant rats compared with virgin rats. We determined the abundance of total NCC, phosphorylated NCC (pNCC; pT53, pS71 and pS89), phosphorylated STE20/SPS-1-related proline-alanine-rich protein kinase (pSPAK; pS373), and phosphorylated oxidative stress-related kinase (pOSR1; pS325) in the kidney cortex. We also measured mRNA expression of NCC and members of the SPAK/NCC regulatory kinase network, serum and glucocorticoid-regulated kinase (SGK)1, total with no lysine kinase (WNK)1, WNK3, and WNK4. Additionally, we performed immunohistochemistry for NCC kidneys from virgin and pregnant rats. Total NCC, pNCC, and pSPAK/OSR1 abundance were unchanged in midpregnant versus virgin rats. In late pregnant versus virgin rats, total NCC and pNCC were decreased; however, pSPAK/OSR1 was unchanged. We detected no differences in mRNA expression of NCC, SGK1, total WNK1, WNK3, and WNK4. By immunohistochemistry, NCC was mainly localized to the apical region in virgin rats, and density in the apical region was reduced in late pregnancy. Therefore, despite high circulating aldosterone levels in pregnancy, the aldosterone-responsive transporter NCC is not increased in total or activated (phosphorylated) abundance or in apical localization in midpregnant rats, and all are reduced in late pregnancy. This contrasts to the mineralocorticoid-mediated activation of the epithelial Na+ channel, which we have previously reported. Why and how NCC escapes aldosterone activation in pregnancy is not clear but may relate to regional differences in aldosterone sensitivity the increased K+ intake or other undefined mechanisms.

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.

Previous studies have shown that the anti-contractile effect of the perivascular adipose tissue (PVAT) is attenuated in pregnancy. In the present investigation, we have examined the possibility that this loss of anti-contractile effect could be due to changes in calcium mobilization. PVAT exerted anti-contractile effect against 5-hydroxytryptamine (5-HT)-induced contractions of aorta segments from pregnant and non-pregnant rats and this anti-contractile effect was attenuated in segments from pregnant rats. Nifedipine (10–6 mol/L), an inhibitor of L-type dihydropyridine calcium channels, significantly reduced 5-HT-induced contraction of aorta segments from non-pregnant and pregnant rats with and without PVAT. The inhibitory effect of nifedipine against 5-HT-induced contractions was attenuated in PVAT-free aorta segments from pregnant rats. However, while PVAT reduced the effectiveness of nifedipine in aorta segments from non-pregnant rats, it partially restored the inhibitory effect of nifedipine in aorta segments from pregnant rats. Inhibitors of calcium sensitization, Y-27632 (10–6 mol/L) and GF 109203X (10–6 mol/L), significantly reduced 5-HT-induced contractions of PVAT-free aorta segments from non-pregnant and pregnant rats. Both inhibitors, however, were less effective in aorta segments from pregnant rats. The presence of PVAT reduced the effectiveness of Y-27632 and GF 109203X in aorta segments from pregnant and non-pregnant rats. Protein expression of Rho-associated protein kinase (ROCK) I and II was detected in aorta segments and PVAT from pregnant and non-pregnant rats. There was a reduction in the expression of both isoforms in aorta segments but not PVAT from pregnant rats. In addition, there was no significant difference in the expression of ROCK-I and ROCK-II in PVAT from pregnant and non-pregnant rats. We concluded that the loss of anti-contractile effect of PVAT in aorta segments from pregnant rats could be due to increased influx of extracellular calcium through nifedipine-sensitive dihydropyridine channels.

SUMMARY The secretory response of rat islets of Langerhans was examined during pregnancy and compared with insulin release in normal rat islets. The threshold for a secretory response to glucose was lowered for islets from pregnant rats by comparison with non-pregnant controls. In addition, such islets showed a greatly increased sensitivity to glucose concentrations over the range 3·5–20 mmol/1. Significantly lower fasting blood glucose levels were found in pregnant rats in vivo, compared with controls. Insulin secretagogues other than glucose were tested for their effects on islets during pregnancy. Despite the high baseline of insulin secretion in response to glucose in pregnancy, there was an additional increased secretory response to arginine and theophylline. In contrast to their response to glucose, pregnant rat islets did not display an increased sensitivity to leucine. Glucagon, while it increased the insulin response of normal islets, had no significant effect on increasing the insulin response from pregnant rat islets suggesting that adenyl cyclase activity is already highly stimulated in pregnancy. In addition, the insulin, DNA and protein content of islets during pregnancy were increased significantly above normal values. The results suggested that rat islets are not only larger in pregnancy, but that they possess a more sensitive mechanism for detecting and responding to glucose and other secretagogues.

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.
